Boarfish

Boarfish is a fish having a projecting hog-like snout.

(SS-327: dp. 1524; l. 311'9"; b. 27'3"; dr. 16'10"; s.
20.3 k.; cpl. 66; a. 1 5", 10 21" TT.; cl. Balao)

Boarfish (SS-327) was launched 21 May 1944 by Elec-
tric Boat Co., Groton, Conn.; sponsored by Miss Barbara
Walsh, daughter of Senator Walsh of New Jersey; and
commissioned 23 September 1944, Commander R. L. Gross
in command.

Boarfish arrived at Pearl Harbor 2 December 1944. Be-
tween 24 December 1944 and 10 August 1945 she made
four war patrols in the South China Sea, Java Sea, and
Gulf of Siam. She is credited with sinking one freighter
of 6968 tons and combining with units of the 14th Air
Force to sink another of 6890 tons.

She operated out of Guam (31 August-17 November
1945) on training exercises and then returned to San
Diego, arriving early in February 1946. She remained on
the west coast until 1 October 1946 when she began a cruise
to Midway Island; Marcus Island; Okinawa; Tsingtao,
China; and Guam which lasted until November. Except
for a voyage to Pearl Harbor in February 1947 and one to
Alaska and Canada during July-November 1947, Boarfish
remained in the San Diego area until 15 November 1947.
She then went to Mare Island Naval Shipyard for overhaul
preparatory to transfer to Turkey. She departed Mare
Island 21 February 1948 and sailed, via the Panama Canal
and New London, Conn., to Izmir, Turkey, where she was
turned over to the Turkish Navy 23 May 1948.

Boarfish received one battle star for her service in
World War II.

A. PROLOGUE.

U.S.S. BOARFISH (SS327)

BOARFISH was launched at the south yard of the Electric Boat Company
on 21 May 1944, and commissioned 23 September 1944 at the Submarine Base,
New London, Conn. During the usual thirty day training period conducted
tests, trials, and training, including three days outside the Sound with a
destroyer escort. Fired three exercise torpedoes. Arrived Panama Bay area
for four day's training on 7 November 1944, where nineteen exercise torpedoes
were fired. Made transit to Pearl in company with THREADFIN and DEVILFISH
departing Panama on 15 November 1944, and arriving Pearl on 2 December 1944.
Received voyage repairs, alterations, and training, latter consisting of
convoy exercises north of Oahu, special exercises, and the firing of four
exercise torpedoes. Depermed, and ready for sea 24 December 1944. BOARFISH
equipped with: slip-rings on QB sound head, counter-weighted pull arrange-
ment on QC-JK head (the cable arrangement made these inoperative due to new
type drift stops on sound heads); noise-level monitoring system off the JP
amplifier; cavitation indicator; No. 1 periscope target bearing transmitter
using the keyway system of Underwater Sound Laboratory at New London; DE type
SJT (persistent screen); arma course clock; coco cola
ice cream machine; sound movie projector; two automatic record players; one
transcription player; and two entertainment radio receivers. No ST radar
nor hydraulic periscope hoists.

24 Dec. 1944
1330 (VW) Underway from Submarine Base, Pearl Harbor, T.H., in accordance
     with Commander Task Force Seventeen Operation Order No. 423-44.
     Ordered to proceed independently to SAIPAN , thence to South
     China Sea to report to and patrol for Commander Task Force Seventy
     One. Eight officers and 76 enlisted men on board. Sixteen Mark
     18-1 torpedoes forward; six Mark 14-3A's and three Mark 27's aft.
     Five inch gun mounted aft, one 40 MM gun on forward raised deck.

25 Dec. 1944
     Christmas fair and warm. Exercised the transcription player with
     Christmas music from records kindly delivered by Captain Hull a moment before
     sailing.

26 Dec. 1944
0100 (X) SJ interference, no doubt from three friendlies due to pass about
     60 miles north of us, eastbound. Could not raise them by keying
     the SJ.

4 Jan. 1945
0540 (K) Fell in with escort, PC 1126.
1043 (K) Passed through net, and half hour later moored along port side
     U.S.S. Fulton in TANAPAG harbor, Saipan (berth N-12). The many
     friendly plane contacts enroute are not recorded.

5 Jan. 1945
1700 (K) Underway for patrol after receiving fuel, water, provisions, free
     laundry, free beer and free haircuts from U.S.S. Fulton, besides
     a number of small voyage repair items. Routing as follows: due
     west to Luzon, then north and northwest towards southern Formosa,
     then west-southwest towards HAINAN, then south to area B-9, to
     shift to operational control of Commander Task Force 71 on 13
     January at area B-9.
2315 (K) Released escort, PC 1126.

7 Jan. 1945
0314 (K) Contacted PADDLE on SJ, exchanged recognition signals and calls
     on SJ key. He was probably 18 miles to the south. It will be best
     to keep to the right in this lane.
0844 (K) Lookout sighted plane at 10 miles; probably friendly, but dove. We
     were using our SD-5 on microsecond keying between one and two
     minutes. ABK turned on. We did not challenge him with the BN. No
     XCV signals.
     No mention is made of several SD contacts made which showed proper
     IFF and no action was taken.
2022 (I) Exchanged recognition signals and calls with LAPON east-bound to
     the south of us, over SJ key.

8 Jan. 1945
0959 (I) Dove for friendly plane that closed from 20 miles to 8 miles.
(A/C #2) Due to Japanese ability to trigger off the ABK and to even show
IFF, we dive on all contacts inside 8 miles. We are now 300 miles
east of Manila. Turned off ABK, continued microsecond keying of
SD-5, and one minute searching out of five minutes on the SJ.
1032 (I) Surfaced. More SD contacts this morning, but none closed too much
and all showed IFF.

9 Jan. 1945
0925 (I) Dove for SD contact at 10 miles, closing to 8 miles. No time to
(A/C #3) try BN.
1656 (H) Dove for sight contact at 5 miles, closing. Looked like a PBY.
(A/C #4)
1728 (H) Surfaced.
2251 (H) Dove for SD contact 8 miles, closed to 6 miles. Dark night.
(A/C #5) Probably friendly. The SJ is kept silent four minutes out of every
five, the SD keyed 1/10 second every one to 2 minutes. They are
no doubt using excellent radar planes, and our XCV is not working,
as we have not picked up anything on it since SAIPAN. Ground
readings on antennae are very low (2000 ohms). Even though big
things are going on along the west coast of Luzon, we are surprised
to find such air activity on this side. However, we are 200 miles
east of Manila and do not have knowledge of the progress of the
January 8th project. Turned ABK back on for all SD contacts.
2310 (H) Surfaced.

10 Jan. 1945
0500 (H) About 30 miles off east coast of Luzon, turned north to parallel.
0717 (H) Dived for SD contact 13 miles, closed to 8. Did not show IFF
(A/C #6) reply to our BN.
0738 (H) Surfaced.
0828 (H) A friendly plane, showing IFF, came in and out on SD from 16 miles
to nine miles, and finally called us on VHF "hello sub. Sub from
plane. How do you hear me. Over." By the time we were ready to
reply he had opened out and was lost on SD. Would have liked to
inquire how things were going on the other side of Luzon. Our
density of air patrol looks good.
0944 (H) Broke down aircraft contact report. (NR 540) regarding a submarine
diving, which plotted out to be BOARFISH yesterday morning (A/C #3).
The plane's reported position was six miles different from where we
had ourselves plotted.
1336 (H) Dived on sight contact of unidentified plane, 5 miles.
(A/C #7)
1435 (H) Surfaced.
2300 (H) Picked up various islands of the BABUYAN group on the SD radar
north of LUZON, altered course to the northwest. Proceeded through
the islands using SJ and SD radars. No moon.

11 Jan. 1945

0500 (H) BABUYAN Island abeam to port six miles. Some indication of
radar; but XCV not working well.
0643 (H) SD contact at 8 miles, dived. B.BUYAN and B.TAN Islands clearly
(A/C #8) in view. Had planned to be a little further ahead at dawn, but
head seas slowed us up last night.
0905 (H) Surfaced. Batan Island 20 miles to the northeast.
1136 (H) Sight contact on biplane float-type plane at 10 miles. SD picked
(A/C #10) him up a few moments later. He did not close, but disappeared
into the northwest. Tried BN on him, no reply. Expect he was a
Jap. Momentary pip on SJ on correct relative bearing at 25,000
yards. SJ is performing much better now that we've got the lower
assembly alignment on BATAN Island at 25 miles.
1411 (H) Lookout sighted "a stick floating up in the water" on the starboard
bow 500 yards. OOD swung ship right to ram, but couldn't turn
sharp enough, so swung hard left, put on four engines. When the
Commanding Officer reached the bridge, there was about 8 foot of
thin black periscope dead astern at 1000 yards in clear view of
OOD, C.O., and lookouts. We opened at high speed, fish-tailing
moderately. Later, when lookout was questioned, he said it looked
too thin for a real periscope and that he had seen a rusty, ball-
shaped object at the bottom end, a bit below the surface of the
water. He was quite sure of this, so sent in dispatch report of
possibility of dangerous decoy periscopes existing. We felt this
transmission was warranted in view of the many surface ships operat-
ing in these waters and the general propensity to ram an unfriendly
periscope. BOARFISH serial two. Position 20-42 N, 121-44 E (LUZON
Straits). Needless to say, altered our own doctrine accordingly.
Our XCV not a U.S. scope, or facsimile thereof, as it had no taper.
1930 (H) Indication of radar on southern tip of Formosa, 150 mgs. Our
XCV antenna still grounded out, so hooked up VHF antenna to the
APR receiver. This is working well. Altered course to the west-
southwest towards HAINAN. From now on the XCV radar search gear
will be called the APR, as it is now the same as a regular APR
since the antenna array is disconnected. See discussion on RADAR.

12 Jan. 1945

Surface cruising, passing 120 miles to seaward of Hongkong.

13 Jan. 1945

0601 (H) SJ radar contact port bow, 7700 yards. Turned away to track, but
lost it. Various courses, searching. Still dark.
0602 (H) Plane on SD at 36 miles, faded out.
0655 (H) Getting lighter, sighted friendly submarine at 8500 yards. Ident-
ification very easy with our unique shears. Closed and spoke SEA
ROBIN by searchlight. He gave us information on convoy reported to
be 30 miles bearing 220, course 220, speed not given. Took over
contact from him and he left for his plane guard station to the
north. The reason we had lost contact with him earlier was that he
dived shortly after our initial contact. There was no SJ inter-
ference. Expect he was using his ST. Position 19-35 N, 111-59 E.

13 Jan. 1945 (continued)

0802 (H) SD contact 20 miles closed to 10 miles. Dived. Set up search
(A/C #10) plan using 10 knots for convoy speed. Got torpedoes on charge
and secured.
0953 (H) Surfaced. Started chase at 18 knots.
1136 (H) SD contact 19 miles, closed to 8, dived. Don't believe they are
(A/C #11) homing on microsecond keying of SD. Could be radar-equipped
planes, possibly friendly, but IFF shows no response. Rather than
blaming the SD, we feel it is doing a swell job. There is, certainly
no follow-up if planes are hunting us. See Remarks.
1219 (H) Surfaced. Resumed chase.
1615 (H) Sighted a floating mine with horns. Fired 3 pans of 20 MM
at 400 yards. Observed three or four hits. It neither exploded
nor sank. Assumed it inert and proceeded chasing convoy. Expenditur
of more ammunition not believed sound with the patrol not yet started
Position 18-08 N, 111-05 E.
2000 (H) Passed over control to CTF 71, set watch on VIXO.
2007 (H) APR contact, 192 mgs, 1000 p.r.f., 5 microsecond pulse width.
Probably an sound on southern end of HAINAN. Held this off and on for
several hours. Land on SJ at 42,000 yards. Also on SD.
2200 (H) Gave up chase of convoy, having thoroughly swept the area between
the coast of HAINAN and longitude 111-30 E. The lack of speed
information made contact very doubtful. Altered course to the
south, proceeding to area C-2 in compliance with dispatch orders
and welcome just received from CTF 71. Kept an overlap watch on
NPM schedule overnight. This made a very busy radio room, as we
were also guarding VHF (loud speaker), Radio Chunking at set hours,
wolf-pack frequency, and China plane reconnaissance on 8000 band
when possible.

14 Jan. 1945

0700 (H) Entered assigned area C-2 from the north.
0947 (H) SD contact 6 miles, dived. Poor visibility, solid overcast. Peris-
(A/C #12) cope patrol on SAIGON-HAINAN route. Seas quite rough from the north-
east, visibility poor. Fleet air strike called for today on
HAINAN. Mention made of an air-surface zone for today only, which
we don't have.
1847 (H) Surfaced. Patrolled six miles off the coast of INDO-CHINA in the
southern part of C-2 in heavy seas and a 30 knot wind.

15 Jan. 1945

2045 (H) Submerged patrolling in 40 fathoms of water five miles off shore.
Received message regarding two groups of downed aviators about
30 miles to the south, close to the shore. Reversed course to the
south and closed points at 3 engine speed. Seas quite rough with
a 30 knot wind from the north. A 1.8 knot set to the southward,
parallel to the beach, would place these rafts many miles south of
their reported position. The information was two days old.

16 Jan. 1945

0027 (H) Abandoned search, as we have passed by both reported positions
and visibility is only 500 yards between rain squalls. Hope
that just by chance we would see a Very's flare or hear some-
thing on 500 kcs. from their Mae West (if they have one - they
were VT carrier crews). Heard later that ROCK found one aviator
and that no others were missing. Will be interested to know
how anybody did in this weather. Reversed course to the north,
returning into our area.
0635 (H) Dived for submerged patrol 5 miles off beach.
0720 (H) Weather somewhat worse. High seas from the north, wind about 35
knots. First look after sunrise showed a fair-sized tanker beached
starboard side to. Seemed to have a broken back, seas beating over
it. stack - high. Position 14-18 N, 109-09 E. MMF tanker of
about 6500 tons. No signs of life or salvage. Proceeded north
submerged. Sea too heavy today, ran at 100 feet, wasted day.
1900 (H) Surfaced in heavy seas, having moved nowhere all day. Tanker still
visible. It looks like a two knot current to the south, with the
wind from the north. This agrees with published data.

17 Jan. 1945

0005 (H) Sighted a good-sized oil fire, set well back from the shore, that
burned for nearly two hours. Approximate position guessed to be
15-00 N, 108-50 E. We are patrolling the straight section of shore
between NUOC Island and CAP BATANGAN in 30 fathoms of water, four
to six miles off ashore, both day and night.
0650 (H) Dived.
1905 (H) Surfaced. Various irregular lights sighted along the beach.

18 Jan. 1945

0646 (H) Dived.
1903 (H) Surfaced. Saw many bancas, canoes, etc., hauled up on the beach
today, nothing afloat. Took over southern half of our area (14 N
to 15-15 N), KRAKEN in northern half. Patrolled mostly off CAP
SAHOI (14-40 N) five miles off the shore.

19 Jan. 1945

0644 (H) Dived. Worked down towards NUOC Island and saw our tanker still
beached.
1903 (H) Surfaced.
2024 (H) Set out to the southeast on two engines to get ahead of a plane
report of 1 AK and 4 escorts off HAINAN this morning, coming south.
Assumed their track would be towards Singapore.
2130 (H) Sent out our intention on wolf-pack frequency for benefit of ROCK
and KRAKEN. No receipts.
2330 (H) On their assumed track, two hours ahead.

20 Jan. 1945

0400 (H) Turned back to the coast, having overlapped enemy about five hours.
Can get back in time to guard the coast if they stopped by
TOURINE instead of coming south. Plane contacts are rather un-
satisfactory as theirs is presumably a short observation during which
the enemy may be on a leg 50 degrees or more from their base course,
and their speed is merely an estimate of their wake, no doubt
difficult to judge in heavy seas.
0647 (H) Dived four miles from NUI ONCAN Islands (13-55 N) two hours ahead
of assumed convoy. Ran north all day and didn't move 5 miles.
Current at least 2.0 knots to the south. Routined torpedoes having
not let up a bit, still 25 knots from the north-northeast, some-
what more.
1903 (H) No contact, surfaced. Have not seen even a sampan yet. Admiral
Halsey's Third Fleet seems to have cleared the waters thoroughly.
2300 (H) Spent some time tracking what turned out to be side lobes on land.

21 Jan. 1945

0210 (H) SJ contact on port bow 7600 yards, turned away. Developed into two
(S/C #1) pips tracking south at 15 knots, close to shore.
0237 (H) Battle stations torpedo. The night was dark, overcast, occasional
faint stars breaking through, half-moon already set, occasional light
rain squalls resembling drizzle, seas calm to moderate from the
north, four to six foot swells.
0303 (H) Six pips distinguished on PPI scope, five in sight at 3500 yards on
the bridge. Nearest one looks like a DE. Tracking very well at 15
knots, with only two course changes, 150 and 170.
0311 (H) Fired six bow tubes, Mark 18's, set at four feet, at closely grouped
multiple targets, two at center, two at left ship, two at right ship,
Angle on the bow looked like about 30 or 40 port, TDC using 60 as
a result of tracking. Track angle 80 port. Could possibly be a
zig toward us at just before firing time. Span of all five ships about
four degrees. Range 1600 yards. Turned away and opened out.
Position 13-52 N, 109-24 E.
0317 (H) One explosion, no hits observed. Target group now spread out but
still on steady course and speed. Sent out contact report on wolf-
pack net to VIXO.
0322 (H) Range 7000 yards, turned south to parallel and work ahead. Even
with this short head start, their 15 knots makes it a long chase.
We lose sight of them at about 4000 yards. Believed we missed be-
cause a zig towards. Convoys are pretty scarce now, and determined
to work this one over proper.
0504 (H) Sent out second contact report to VIXO and on wolf-pack frequency.
Have no confidence in wolf-pack frequency as no one answers or
receipts.
1520 (H) In good position at 3000 yards, 120 port track on what still looks
like a DD or DE. Studied him over carefully this time. The DE was
nearly dead ahead, and a little to the left at about 3500 yards
were the dark shapes of the others, details not distinguishable.

21 Jan. 1945 (continued)

0521 (H) Near DE flashed a challenge at us with a white light, so fired
          3 bow tubes at him, MK 18's set on six feet, at 3000 yards range,
          125 port track, small gyros, then swung bridge TBT to the left and
          fired three more of the same at the indistinguishable ships. These
          last three were not carefully aimed at a single vessel, but spread
          at a group of two or three ships, one in the middle and one at
          each limit of shape. Used six feet because of the moderate swell,
          although firing across the swell. Turned away and opened out. No
          explosions heard, no course or speed change. Strangely enough, there had
          been no change in target who challenged us. Position 13-19 N, 109-26 E.

0532 (H) Range 5800 yards, turned to parallel and work ahead. At this
          point should have realized that ships were small, and we should
          have pulled well ahead for a daylight look. However, we wanted too
          much to have BOARFISH score on the enemy, and if these got by no
          other opportunity might arise. Got a target length of 2 degrees at
          3000 yards which gives 300 feet, which convinced me they were suit-
          able targets. Believe now this was a poor estimation of field
          intercept by the Commanding Officer.

0605 (H) In good position for a stern shot, but nearest ship turned towards,
          and we turned also to parallel. He then turned away and we had to
          close so it called for the bow tubes again.

0612 (H) Fired four bow tubes, Mark 18's set on six feet (still felt that
          the good depth and steering performance at six feet a better risk
          than the sometimes erratic runs noted in patrol reports on zero
          settings - and any 300 foot ship should draw better
          than six feet), two at right hand target, 80 port track, and two at
          left hand target, 84 port track, range to both about 3000 yards.
          Gyros were favorable and fire control had been checked between
          attacks. Targets quite clearly seen this time - single mast abaft
          the bridge, single low funnel, angle on the bow called 90 port, 60
          from the TDC, so used 70 port. Both targets looked the same.
          However, this description would also fit a PC type. No explosions.
          A light rain started, dawn breaking all around. Position 13-09 N,
          109-25 E. Opened out to 10,000 yards and made full power to work
          ahead again. Lost considerable ground getting outside his daylight
          visibility range (12,000 yards). Occasional rain patches (not real
          squalls) helping a lot.

0719 (H) Sighted two of them dead ahead 8000 yards in a rain cloud. Turned
          out to seaward again.

0740 (H) Heard one explosion. Possibly ROCK getting in an attack. Position
          13-03 N, 109-38 E, but drift of 1.5 to 2.0 knots to the southward
          makes position doubtful. Sent out a third contact message, no
          answers on wolf-pack, so sending it to VIXO. This was re-run on the
          schedule 22 minutes later.

0830 (H) Visibility lifting all around. Shore line easily visible at 12
          miles. Although we are still 5 miles behind them, we will not
          be able to work ahead this close to the coast in good visibility
          before they will reach CAMRANH BAY at 1100, so closed coast in a
          rain cloud.

0903 (H) Dived on a line between two promontories just south of CAPE
          VARELLA, in good position to intercept coastwise traffic and to
          see our targets of last night if ROCK succeeded in slowing them
          down. Being in someone else's area and in a likely position,
          sent out the challenge on the sound gear every two hours. Heard
          what sounded like single pings about every hour, but no other
          contacts.
1912 (H) Surfaced about 8 miles off shore, half moon at the zenith, weather
          clear and calm; Sent out our serial one regarding torpedo expenditure
          etc., and headed north to our area 120 miles away. Allowed myself
          to feel milk. The ship fired her first war shots in an excell-
          ent manner. I am convinced our control was precise and exact, and
          that if those ships had been of legitimate size, we would have had a
          field day. Besides, we still had six Mark 14's aft.

                                                22 Jan. 1945

0655 (H) In our area, dived for the day. Sighted our friend the beached
          tanker still in position.
1100 (H) Heavy smoke on beach, looks like a big fire. Position 14-10 N, 108-
          52 N, later identified as a burning beached tanker, not the same
          as the previous tanker seen.
1225 (H) Sighted one BETTY following coast going south. He circled scene of
(A/C #13) fire and continued on south.
1640 (H) Sighted 2 NATES, zero angle on the bow, 4 miles, approaching periscope
(A/C #14) depth to 120 feet.
1700 (H) Periscope depth, all clear.

                                                23 Jan. 1945

0100 (H) Plans for rendezvous with CHERR fell through due to radio dropping
          one dot and sending a U instead of an F, thus causing a fifty nine
          mile error in the meeting point. Fortunately there was nothing ur-
          gent to discuss.
0235 (H) Converted No. 4 FBT to MBT. Required 40 minutes. Our vent screens
          are merely large expanded-metal bulkheads in the superstructure which
          allow men to work unhindered in a six or eight foot square.
0641 (H) Dived five miles off coast near CAP SAHOI, closed shore for sub-
          merged patrol. Weather now very fine. Many sailing bancas all around
          from patrolling at discretion north of latitude 15 N.
0945 (H) Sighted two RUFES flying low along the coast.
(A/C #15)
1121 (H) RUFES following, probably same two seen at 0945.
(A/C #16)
1925 (H) Surfaced. Patrolled north of CAP SAHOI five miles off shore, avoided
          many fishing sampans and bancas.
2001 (H) APR contact 192 mgs., p.r.f. 800, pulse width 10 microseconds;
          sweeping slowly about every 2 minutes. Probably CAP BATANGAN.

0628 (H) Dived 5 miles off CAP NUOK, closed to four miles.
1101 (H) Sighted a PBM with a DAVE escort flying low along the shore.
(A/C #17)
1924 (H) Surfaced, patrolled five to eight miles off shore. Weather fine,
moon four days from full.

25 Jan. 1945

0639 (H) Dived five miles off coast near CAP SAHOI.
1205 (H) Sighted two DAVE's flying south along coast.
(A/C #18)
1924 (H) Surfaced. Patrolled close to shore between CAP NUOK, avoiding
many sailing vessels. These appear at about 4000 to 9000 yards
on the radar, but always develope into sailing vessels when closed.
Lookouts generally see them first these bright moonlight nights
even when overcast. Calls for a lot of section tracking drill.

26 Jan. 1945

0017 (H) Possible distant explosion.
0639 (H) Dived 4 miles off CAP SAHOI, patrolled submerged 4 miles off
shore. 30 fathoms of water. Current still 1.0 to 1.5 south.
1520 (H) Sighted plane similar to our PBM, following shoreline at about 800
(A/C #19) feet altitude, going north.
1530 (H) Sighted two barges or sea trucks apparently 500 yards off the
beach, going north.
1600 (H) First of three junks, Hongkong style, passed close aboard headed
south. Appeared deeply laden. Charr now patrolling south of us,
so prepared a message for her regarding the sea trucks as good gun
targets, which was never sent.
1638 (H) QB picked up echo ranging in the south, set course to the northwest,
to close beach further. Visibility good, sea flat.
1654 (H) Screws on JP. Must have been 15,000 yards away although nothing in
sight against shore-line.
1741 (H) Screws on QB now.
1747 (H) Sighted convoy of one AO and two DE's coming north very close to
(S/C #2) shore. Hard to see against land at 55 feet depth. We are now
10,000 yards off the shore, 6000 yards off their assumed track,
closing easily at 2/3 speed.
1803 (H) Battle stations. Oiler about 6000 tons, engines aft. Escorts new
type of DE shown as UN-1 on page 141 of ONI 222-J. Clean and neat
looking. Looked like we'll get in nicely just about sunset. Range
now about 8000 yards, 60 starboard angle on the bow. Tracking at
8½ knots.
1827 (H) 80 starboard, range 5000 yards.
1838 (H) 90 starboard, range 4000 yards, beginning to open. They must have
been not more than 1000 yards off the beach in 10 fathoms of water.
The sun now set. Opened out to east to surface and chase. Might
have gotten in if we had run at high speed submerged. Considered
firing anyway with our Mark 14's aft, but glad we didn't as they
tracked later at 10.5 knots, and the wakes could have been avoided
at long range in the flat sea before sunset.

Position 14-53 N off CAP MIA, Charr patrolling south of us
unfortunately.
1918 (H) Surfaced and picked target up on radar at 23,000 yards. It will be
a difficult chase if he is headed for TOURANE and hugs the coast.
2021 (H) Radar interference, 10 cm., on SJ screen but not on APR.
2035 (H) Drawing ahead slowly, about 14,000 yards off their track. Enemy
tracking at 10.5 knots. Chase occasionally loses some ground to
avoid junks and bancas.
2140 (H) Target group has rounded CAP BATINGAN. Their having the inside track
makes our route considerably longer. Now inside KULAO RAI Island
in good view at 12,000 yards on the port beam, KULAO RAI Island
about a similar distance to starboard. Radar interference persists
but does not steady down on us.
2143 (H) Seaward escort closed to 9000 yards suddenly. Seemed to have a
small starboard angle, and closing rapidly. Attempted to open to
the north, but range closed slowly to 7500 yards.
2155 (H) Passed two floating mines close aboard. Angle on bow of escort zero,
range 7400 yards closing slowly. Bright full moon, visibility
excellent. VOLTA bank to the north, KULAO RAI Island to the east,
so turned to the southeast at best speed to lose the escort.
2158 (H) Range to escort 7150 yards. Planned to dive at 6900 yards. Range
now began to open. We were logging 20.2 knots. Believe escort's
top speed was 15 knots. Escort in plain view, showing a small star-
board angle. Believe he did not have us on his radar, but could
possibly have seen us. Unfortunately the geography did not give us
full freedom of choice as to courses.
2230 (H) Lost sight of escort. Check now showed that we could not catch
tanker before it reached TOURANE.
2242 (H) Gave up chase and sent contact report to China planes.
2303 (H) Sighted another floating mine.

27 Jan. 1945

0347 (H) Made rendezvous with CHARR to pass miscellaneous information.
Decided for both of us to patrol close to the coast as it seems
traffic really does "hug" the coast. In maneuvering alongside to
speak CHARR, we touched forward, placing a dent in his port bow
superstructure and denting our bow slightly. No damage to either
ship. Gave CHARR all north of 14-30, we taking from 14-00 to 14-30.
0450 (H) Sighted the glow of burning tanker on the beach. This ship has been
burning ever since we first saw it on 22 January. It makes a
good navigational mark, being located at 14-11 North.
0644 (H) Dived near CAP NUOK patrolling 4 miles off shore. Got a good look
at shore in vicinity of CAP NUOK and counted a total of four ships
beached here as follows:
1. The large tanker first sighted on Jan. 16 at Lat.
14-18 N. Very large, possibly 12,000 tons.
2. A MFM, in the rocks off NUOK at Lat. 14-15. Medium
size, stern under, about right angles to the beach.
3. An unidentified one just north of the rocks at NUOK,
showing only two masts, at Lat. 14-14.

4. The burning tanker, stern under, bow high and burning
brightly at Lat. 14-11. Size undetermined, foremast
had heavy cross-trees, bridge out of water, stack and
stern out of sight. Took pictures at 5000 yards.
1043 (H) Sighted one MAVIS cruising aimlessly over shoreline.
(A/C #20)
1205 (H) Three barges or sea trucks coasting about 100 yards off shore,
headed south.
1418 (H) Sighted flying boat similar to our PBM flying along the coast.
(A/C #21) He headed for our periscope as in an attack, Went
to 100 feet, nothing dropped. Seas unfavorable for him to stay
at 2 miles.
1809 (H) Sighted one DAVE flying south.
(A/C #22)
1912 (H) Surfaced.
Figured out tonight that those planes that looked like
PBM's were PBM's, and they were searching for downed aviators. We
had this information in a dispatch, but did not connect the two.
These search planes must be out of MINDORO, a long reach for them.
Told CHARR to watch for the aviators in her sector, we to watch
in ours. The possible territory described in the
dispatch consists of 80 miles of coast, as the plane was downed in
land. Our highest respect to the patrol plane pilots flying at
800 feet over enemy territory, contact with enemy planes more
maneuverable and speedy being certain.
2351 (H) Passed a floating mine close aboard, easily visible in the full
moon. Also many SJ contacts on sailing and fishing vessels.

28 Jan. 1945

0708 (H) Dived in squally weather four miles off CAP NUOC. Visibility var-
iable, current 2.0 knots to the south. Got set up aft for four
Mark 14's in the tubes, and two in the racks, instead of 3 and 3
as before.
1917 (H) Surfaced.

29 Jan. 1945

0642 (H) Dived between NUOK and BUFFALO Island. Good patrolling weather.
0913 (H) Sighted one DAVE flying north along coast.
(A/C #23)
1115 (H) Sighted a PBM flying north along the coast.
(A/C #24)
1200 (H) Figured length of beached tanker at 14-18 north to be 500 feet by
horizontal periscope angle.
1238 (H) Sighted a large seaplane, possibly a PBM heading for periscope.
(A/C #25)
1352 (H) Sighted LILLY or NELL flying north along coast.

1916 (H) Surfaced. Patrolled five to eight miles off NUOK. Used burning
       tanker on beach as a good land mark.
2315 (H) Heard from PBM plane that CHARR she picked up one survivor and had made arrange-
       ments to return each night for 3 nights to pick up remaining ten
       survivors from PBM plane No. 206. Position of rescue on shore at
       Lat. 14-37 N.

. 30 Jan. 1945

0631 (H) Dived between NUOC and BUFFALO Island.
1220 (H) Sighted the usual morning PBM patrol plane, heading north.
       (A/C #27)
1434 (H) Sighted RUFE flying south to seaward of us.
       (A/C #28)
1451 (H) Sighted another RUFE to seaward.
       (A/C #29)
1512 (H) Screws on JP to the northeast.
1516 (H) Smoke and pinging to the northeast.
1525 (H) Identified target group as 2 CL's of the KATORI class screened by
       (S/C #3) four DD's or DE's. Angle on the bow was 50 starboard at 15,000
       yards.
1620 (H) Watched them go by 10,000 yards to seaward of us at 20 knots. One
       or two plane escorts seen. We were patrolling close to shore
       near BUFFALO Island.
1713 (H) One of the escort planes still in sight, appears to be circling
       a position 10 miles south of us. Could be PARGO spotted.
1759 (H) Sent out contact report on SD antenna on wolf-pack and ship-shore
       frequencies. No receipts or replies.
1822 (H) Plane no longer in sight, 15 minutes till sunset.
1921 (H) Surfaced. Sent out contact report on both wolf-pack and ship-shore
       frequencies again. Charr unfortunately to the north on her rescue
       job.
2025 (H) Pinging on QB gear. Indications of radar at 120 mgs. on APR.
2031 (H) Nothing in sight, but pinging from two sets of gear. Battle
       (S/C #4) Stations. SJ contact to the southwest at 12,000 yards.
2037 (H) Moonrise, occasional clouds, flat calm sea, clear visibility. Two
       or 3 targets on radar, closest at 8000 yards.
2045 (H) Target group tracks close to the beach at 10 knots. Decided to
       lie close to BUFFALO Island, a good-sized group of rocks 100 feet
       high, using it as a screen against sighting and radar contact. They
       should pass about 3000 yards away. Closed BUFFALO Island to 900
       yards dead slow from the south, keeping in line between the island
       and the target group now in sight. 10 cm. interference on our SJ scope
2125 (H) OOD reported some concern over near escort now at 6600 yards small
       angle on the bow, but we felt sure we were not seen nor distinguish-
       able from the rocks on any radar they might have.

30 Jan. 1945 (continued)

2126 (H) Gunfire from nearest escort. Shooting AA in our general
           direction but not too close. Black puffs clearly seen at 3000
           ft altitude, some port, some starboard. Cleared out at full speed
           inshore of the island. Range opened nicely. Escort seen to circle
           to seaward of the island. We believe they did not have us on
           radar, but may have had us on radar search gear. Escorts track at
           14 knots maximum, main targets (two) not yet seen clearly against
           land background.
2150 (H) One escort on our starboard quarter, and one on our port quarter.
           Range steady at 5000 yards. Target group seems to be stopped close
           to shore.
2154 (H) More gunfire. Range opening slowly and no sign of good shooting,
           so continued on surface. Our course is northerly, favorable to head
           them off again.
2202 (H) Gunfire has stopped. About 10 rounds were fired by both escorts
           combined. Slowed to 15 knots.
2214 (H) Range now 9000 yards to near escort, more gunfire, still AA bursts.
           Shooting, although in our general direction, is random. Opened out
           again to the north. Decided he was homing on our SJ. Secured it
           except for quick looks every 3 minutes. Their power was not of
           the fleshless kind. It made a large orange burst. However, the
           AA bursts were flashless. Last shrapnel was heard to whistle. Sent
           out contact report on wolf-pack frequency.
2328 (H) Tracking from ahead at 12,000 yards on their starboard bow, when
           escort suddenly appeared at 8400 yards closing. Made full power, but
           range closed to 7300 yards. As we were well ahead, decided to
           draw no more gunfire.
2342 (H) Dived to look him over. Opened track 45 degrees. He closed to about
           2000 yards, circled our diving swirl, dropped one depth charge, and
           made off to the west to rejoin his convoy. He appeared to be a
           single stack clean-lined ship, with gun mounts forward and aft.
           Not a CHIDORI nor a DE-UNT, and not a PC. Possibly a DD or a CM. Had
           a good look at him in the moonlight as he circled the diving point.
           Pinging continuously on long scale. We are six miles off TAMQUAN
           in 30 fathoms of water ( 14-31 N, 109-12 E).

31 Jan. 1945

0032 (H) Surfaced. Targets due west of us, practically on the beach at
           11,000 to 14,000 yards. Radar has great difficulty distinguishing
           targets from gently-shelving shore lines. Found the steerable sweep
           feature very good for this on the PPI. Used SJ sparingly. There
           has been no more radar interference on the SJ scope, and none on the
           very unreliable search equipment.
0242 (H) Now well ahead and undetected seven miles off shore. Closed the
           beach. Battle stations again.
0247 (H) Picked up escort due south, 8000 yards. Another one southwest.
           Apparently we are not getting far enough ahead. However, we lost
           target at 10,000 yards. Decided to open well out to the north,
           choose our spot, dive, and wait for them.

0400 (H) In good position just north of Cape MIA in 30 fathoms of water,
about three miles off shore, dived. Contact on JP and QB sound
gear. A flat, bright moon, occasional clouds, excellent
visibility through the 1.99 periscope.
0420 (H) Targets in sight showing zero angle. All three escorts to seaward
of the two targets. Estimated range 5000 yards.
0440 (H) Both targets showing small port angles, escorts still on the far
side to seaward.
0446 (H) Fired two Mark 14's at leading ship, 107 port track, depth set 6 feet
run 1500 yards, target speed 10.5 knots, gyros 175.
0447 (H) Fired two Mark 14's at trailing ship, 80 port track, depth set 6
feet, torpedo run 1700 yards, same target speed, same range, gyros
201.
0448 (H) One hit exactly in the middle of the first target.
0449 (H) One hit exactly in the middle of the second target. First target
was a MM with no funnel noticed, full field at time of firing giving
about 450 feet length for range computed from torpedo run. Second
target was a MMF of about the same size although no measurement
was taken of it.
0452 (H) First target stopped dead in the water, began to settle on an even
keel, no fire or smoke. The second target made heavy black smoke
from her stack and turned hard away, seeming to still have motive
power. Sound was busy on the escorts and we have no sound
on the target's screws. Escorts well to seaward. Reloaded
of our last two torpedoes aft. Estimate both ships to
be 6500 tons, and second target possibly a type 45 MKKMF, a new class
shown in ONI Weekly, Vol. III, No. 47, Nov. 22, 1944.
0458 (H) Escorts in sight, closing, angle on the bow zero. Stopped reload.
0500 (H) Took a quick last look. First target very low in the water with no
awash, stopped, settling on an even keel, second target still
showing heavy black smoke from the stack, heading for the shore.
All three escorts in sight showing small angles. Went deep, to 120
feet.
0505 (H) First of twenty two depth charges, all seemed medium close to close.
No damage except tripped out IC power which was immediately re-
gained, and set off the bridge diving alarm, which seemed to sound
a long time after the circuit was opened. DCDI gave good indica-
tions; and all of the lights lighted at different times making the
escape course uncertain. However managed to work to seaward with
one escort on each beam and one astern. Do not believe they ever
got a return echo for their pinging.
0734 (H) Planed up to 63 feet. One of last night's escorts 9000 yards west
of us, toward the shore and the scene of attack. Decided to lay low
today and see what developed tonight.
0820 (H) A second DD or DE seen at 10,000 yards, patrolling close to shore.
1514 (H) Sighted a NELL to the north circling.
[HANDWRITTEN: (A/C #30)]
1543 (H) Several sharp distant explosions, believed to be air bombs.
1601 (H) One explosion.
1647 (H) One explosion.

1718 (H) Thirteen distant explosions, depth charges. Bluish smoke seen
in direction of our attack last night and in direction of pinging.
1743 (H) Twelve depth charges, distant.
1744 (H) Two float-type planes over coast flying south. About 50 more depth
charges heard in the next hour.
1840 (H) Sunset. DE's not in sight, but pinging heard and bluish smoke in
sight near shore. We are about 8 miles from scene of attack. A
total of some 80 depth charge explosions heard this afternoon.
1923 (H) Surfaced. Closed coast to investigate.
2050 (H) Heavy oil slick 14-53 N, 109-01 E, probably from sunken first tar-
get, about ½ mile wide, limits of length never seen.
2120 (H) SJ contact 283 (T) 6000 yards. Tracked contact and picked up echo
ranging. Finally sighted DE, plotted him patrolling at 12 knots
parallel to shore. Had two pips on radar on the beach at 11,000
and 14,000 yards that might be our ships, plotted stopped. Sent
information to China group and to CTF 71.
2205 (H) Moonrise. Opened out slightly to await results of CHARR's attempt
at rescue. No radar interference, no offensive action by DE. Lay
to at 16,000 yards from the beach off the scene of attack. Continued
to plot one DE patrolling about 3 miles off the beach and parallel
to it. Estimated the situation as follows: One or both of our
targets inshore, disabled but of some value still, screened by one
DE. Believe there was another DE to the south. Two Mark 14's re-
maining aft. Little chance of salvage getting far by morning. Charr
still occupied with rendezvous with aviators. Decided to await
daylight again maintaining a radar watch on the shore. Pinging
still heard from DE in the sound gear most of the night, but ship
not on the radar screen. Weather clear, glassy calm, speed of
patrolling DE 12 to 14 knots.

1 Feb. 1945

0030 (H) Heard from CHARR she made rendezvous and no additional survivors
were present. This was third and last night.
0637 (H) Dived to observe. If situation unchanged tonight, decided to plan
a diversionary attack on DE's and have CHARR go in to
targets, if possible.
0650 (H) The same two DE's in sight at about 7,000 yards, patrolling at
12 or 13 knots (160-180 rpms). Several sailing vessels sighted.
We hope that today the China planes will either attack or give us
some information.
0840 (H) Sighted a DAVE over the coast, flying north. Sighted another half-
(A/C #31) hour later flying south, believed to be the same plane.
1833 (H) Loud rapid banging noise on hull. Could be distant aircraft bombs.
Hoped this was an attack by the China planes. Noise continued irr-
egularly for five minutes.
1917 (H) Large fire on beach in direction of our targets.
1919 (H) Surfaced. Closed shore. Fire identified as a ship burning. Masts
could be seen. Set a watch on the life guard frequency and on 500
kcs. Looks like China planes had done a job. No signs of escorts.

2011 (H) SJ out of commission. It has been performing poorly lately.
(DE's at 6000 yards).
2205 (H) Moonrise, closed towards fire for a look.
2230 (H) SJ back in commission. Weather glassy calm still, but clear.
2300 (H) In 18 fathoms about 3 miles off ship, no escorts left, but cannot
discriminate between the ship and the land on the radar. The
ship was burning hard aft and was an engines aft ship. Smoke was
black, but not sure whether it was a tanker or a cargo vessel.
Believe from strength of fire and black smoke that it was an oil
fire. Opened out from beach, consider her destruction complete. No
signs of life or activity. Estimate that our No. one target sank,
and No. two beached himself and was set on fire by an air attack or
by internal explosions this evening at dusk. It did not appear
likely that the other ship got underway with one escort, leaving
two to guard the beached ship, particularly as No. one target
seemed the hardest hit, being stopped and very low in the water
when last seen.

The source of the explosions this afternoon at sunset is unknown.
I believe if the China planes had acted on our information they wou
let us know. Nothing was received from them. Another
possibility is internal explosions in the ship from unknown causes.
However, there was no sign of fire during our watch until at dusk
today. We hope that CTF 71 has further information from China or
Mindoro planes to corroborate our assumption of two ships destroyed

2 Feb. 1945

0200 (H) Sent information to CHARR, and gave her a patrol station to the
south. Kept cut in on burning ship all night at about six miles
off shore. Told CHARR we would probably rendezvous tonight to
get her on one survivor preparatory to leaving area.
0643 (H) Dived in the middle of eighteen sails.
0753 (H) Counted 43 sailing vessels, some junks, some sampans.
0857 (H) Rain. Took a sounding - 30 fathoms corrected.
0915 (H) One junk getting close.
0921 (H) Planed down to 90 feet to pass clear of junk in case he had lines
out. Touched bottom at 87 feet, damaged JK*QC sound head, pit log
okay. The sounding at 0857 had no doubt been in error. This
proves again that soundings, as well as ping ranges, are worse than
useless unless taken with skill.
0928 (H) Another sounding gave 8 fathoms at 60 feet (18 fathoms corrected).
1000 (H) Got a good look at our burning ship, target No. 2 at 6000 yards:
stack well forward on poop, several ventilators aft of the stack,
heavy cross-tree on the main mast, bridge between fore and mainmast,
raked bow, cruiser stern, medium stack. Measured up by horizontal
angles at about 450 feet long. Fire concentrated amidships and aft;
other details especially forward obscured by dense black smoke.

1039 (H) 88 sails in sight, many of which are junks, southbound. Question
           arises as to whether these junks are legitimate gun targets. No
           set formation, no escort, apparently defenseless. They are Chinese
           junks, southbound, no doubt run by Chinese. However, they may be
           aiding the Japs. This is a debatable question. We elect to
           consider their destruction not commensurate with the suffering that
           would be caused to a friendly people.
1901 (H) Surfaced. Arranged for rendezvous with CHARR.
2100 (H) Received dispatch to proceed to PERTH via KARIMATA and LOMBOK.

3 Feb. 1945

0015 (H) Rubber boat from CHARR brought over HAMILTON, C.L. AFM2c, survivor
           from PBM plane No. 206, and executive officer of CHARR for confer-
           ence.
0100 (H) Boat returned to CHARR, set a southeast course at three engine speed
           enroute KARIMATA Straits, passing along boundary between "C" and "B"
           areas well clear of land.
0600 (H) Departed area "C", having spent 20 days therein.
1625 (H) Maneuvered on the surface to avoid a periscope reported by a lookout.
           Not verified.

4 Feb. 1945

0645 (H) Sighted first of about eight oil drums widely separated, apparently
           empty.
1114 (H) Sighted a plane nine miles away headed for us, dived. Two-engined
(A/C #32) plane flying west.
1151 (H) Surfaced.
2331 (H) Commenced converting No. 3 and No. 5 F.B.T. to main ballast tanks.
           Sea flat calm, held 16 knots while converting. Required one hour.

5 Feb. 1945

0550 (H) Exchanged challenges and calls with BASHAW on SJ key, after much
           SD and SJ interference, and saturation signal on APR having SD
           characteristics. Position 03-00 N, 107-00 E.
1612 (H) Periscope sighted, turned away. Shaped like our barrel with taper,
           showing some stainless steel section of barrel. Range 1500 yards.
           After showing our stern, flashed the recognition signal at it.
           Position 00-51 N, 106-02 E. With many changes made in area assign-
           ment, not sure which boat is in this area, but we are sure one of
           TF 71 boats is assigned. Could have been KRAKEN.
1900 (H) Got indications of SD radar on the APR gear, also SJ interference
           on the SJ scope. This continued intermittently for several days.
           There are five or six south-bound boats and two north-bound boats
           near here.
1915 (H) Davey Jones presented his subpoenas to the pollywogs.
2034 (H) Exchanged challenges and calls with FLASHER (north-bound) on SJ key.

0612 (H) With SERUTU Island bearing 110 T, 6 miles, dived to transit KARI-
     MATA Strait.
1400 (H) King Neptune came on board with party, a relatively simple task in
     78 feet of water.
1713 (H) Royal Party left the ship.
1931 (H) Surfaced.

7 Feb. 1945

0000 (H) Heavy rain and electric storm seemed to affect both the APR and the
     SJ radar. Stopped for 20 minutes until radar screen cleared up.
     Visibility zero.
0640 (H) A U.S. submarine sighted by high periscope astern when day broke,
     about 14,000 yards. Had 10 cm. radar interference on SJ and indic-
     ations of SD on the APR. Possibly BESUGO or HARDHEAD. No luck in
     challenging. Several palm trees and other debris seen to-day, indic-
     ating a possible storm somewhere. Drew away from the submarine this
     forenoon at 16.5 knots.
2000 (H) Received message stating it was preferable to pass to the north of
     KANGEAN Islands in reply to query.

8 Feb. 1945

0100 (H) Passed 15 miles to the south of Great MASALEMBA.
0640 (H) Lookout sighted plane at 8 miles closing. Dived.
0713 (H) Surfaced. Maneuvered around two sailing vessels today.
1817 (H) Sighted high peaks of LOMBOK to the south at 60 miles. Also had land
     on SD at 63 miles. We were all ready to put on four engines for the
     passage when we received notice of a plane contact on a carrier
     group in MAKASSAR Straits heading southwest into the Java Sea.
     Took up a patrol station five miles south of SEPANJANG Island in the
     KANGEAN Islands. Arrived on north corner of MADURA sound. Arrived
     there at his 25 knot position. Notified CTF 71 and all on wolf-pack
     frequency of our intentions. We were only 30 miles from that posit-
     ion and it was a logical route for the carrier to take if he were
     to go to SURABAJA via MADURA sound.
2000 (H) Patrolling on station off SEPANJANG Island.
2250 (H) SJ interference. Exchanged major war vessel challenge on SJ key,
     but could not clear exchange of calls. 9 Feb. 1945
0552 (H) Dived for submerged patrol six miles south of SEPANJANG. Latest the
     carrier should pass is about 1300 at 12 knots.
1915 (H) Surfaced. No contact. Set course for LOMBOK Straits.
2000 (H) APR contact 174 mgs., and 150 mgs., weak.
2017 (H) SD contact sounded like a submarine BK, code being correct.
2025 (H) SJ interference.
2052 (H) Exchanged proper recognition signals on the SJ key with a submarine,
     but his call letters after challenge were unreadable. Probably KRAKE
     ahead of us.
2055 (H) APR signal at 178 mgs very loud. We are approaching northern ent-
     rance to LOMBOK, land about 15 miles away.
2100 (H) SD contact at 12 miles, this side of land.
2104 (H) Watched keying SD close in to 5 miles and dived. Keying SD for 1/10 of a
(A/C#34) second about every minute, but irregularly.

2131 (H) Surfaced, all clear. APR contact at 175 mgs., still there, but weak.
2137 (H) More SJ interference from ahead, probably our friendly submarine.
2230 (H) Lost APR contact.
2235 (H) SJ interference from eastern point of BALI. Could be a bad bearing.
           Looked the same as before.
2246 (H) SJ contact at 8550 yards dead ahead, plotted as probable small patrol
           boat. Worked around him to the west. Passed him 5000 yards abeam.
           Looked on an easterly course at 4 knots.
2332 (H) APR contact at 175 mgs again. Land now at 7 miles on SD. APR
           contact soon faded out.
2354 (H) Picked up a second patrol boat on SJ at 5000 yards. This one very
           small, tracking on a parallel (southerly) course at 4 knots. Altered
           course to the westward, passing him at 4000 yards abeam. Neither
           patrol boat had signs of radar.

19 Feb. 1945

0007 (H) Plane back in again at 178 mgs weak. It was then noticed that he
           showed two separate pulses, one within and shorter than the other,
           on the SPA. He is also keying his radar. It appears that he swung
           his plane till he gets equal pip height, then heads in. This
           helped to warn us, as when the pulses seemed to blend on the SPA,
           his signal became much louder.
0019 (H) APR getting weaker.
0035 (H) Land now at 6 miles on SD, 178 mgs APR contact getting stronger,
           pulses blending in, apparently plane is on us.
0049 (H) Saturated pulse on SPA, louder than our own SD in the phones.
0054 (H) Plane pip on SD inside of land at 4 miles. Closed to 3½ miles,
           dived. We are right in the narrowest part of the south pass between
           LOMBOK and NUSA BESAR. Went to 150 feet, nothing dropped.
0134 (H) Surfaced, all clear. No moon, bright starry night.
0135 (H) Plane still on the APR, weak.
0145 (H) Pit shows we made good 11.0 miles in 57 minutes. As most of it was
           at 150 feet, believe current at that depth and at that time to have
           been close to 7 knots in a southerly direction. Pit log distance
           during that interval was 5.7 miles.
0148 (H) 178 mgs getting louder, land at 7 miles on the SD.
0149 (H) SJ contact astern at 9700 yards, SD plane contact inside of land
           at 5 miles.
0150 (H) With SJ contact at 6400 yards no doubt a plane, and plane on SD at
           3½ miles, dived once more. This time his APR signal was weaker.
           Either he turned his power down to simulate distance, or our VHF
           antenna has a blind spot aft. As we were clear of the straits and
           could expect a favorable current, remained submerged this time all
           day, checking our distance good to seaward by fathometer.

           This plane radar does not check with known Jap characteristics as
           given to us by ComSubPac. It was 178 mgs., 250 p.r.f., 3 micro-
           second pulse width, and resembles our ASB used by our PBY's, except
           the p.r.f. is different.

May be new type. We believe it would have been useless to secure
our SD or our SJ, or both. The SJ was used one minute out of every
five. When both his pips blended into one and his signal got
louder, there was not much doubt that he was on us and coming in.
We will be interested to know if other boats have been forced down
similarly in LOMBOK. We knew night planes could be expected, but
did not know their effectiveness. On the other hand, it is a
source of amazement that we can get through at all.
1910 (H) Surfaced and set course for Fremantle at 3
engine speed in fair weather and calm seas.

14 Feb. 1945

1630 (H) Dived and went to deep submergence for test.
1825 (H) Surfaced.

C. WEATHER.

Pearl - Saipan: Excellent, except for occasional strong northeast mon-
Saipan - Area: Excellent.
In area: First few days were very stormy with the strong northeast mon-
soons apparently well established. This soon deteriorated how-
ever, and remainder of time in area the winds were very light
to zero from the north, east, and west, with flat-calm seas.
Injection about 72 degrees (F), boat very comfortable.
Area to Malay Barrier: Still flat calm seas prevailed, glassy at times.
Barrier to Fremantle: Gentle swells, less than 10 knot winds, variable.

D. TIDES AND CURRENTS.

Average and in accordance with published data. A strong regular set
to the south was found along the INDO-CHINA coast varying from 1.5 knots to
2.0 knots. Running northwest submerged five miles off the coast, we often
made good only five or six miles all day.

At 150 feet running south in southern LOMBOK passage, found 6 to 7
knot current setting southerly. No other unusual currents.

E. NAVIGATIONAL AIDS.

None lighted along INDO-CHINA coast, and none in LOMBOK straits. Other
contacted were by day.

Type Attack - Night surface attack using bridge TBT bearings and radar ranges.
Six Mk. 18-1 torpedoes were fired across a force 3 sea, range 1600 yards,
torpedo run 1500 yards, depth set 4 feet. For 45 minutes TDC and
convoy on steady course 170 T, speed 15. Ten minutes before firing, TDC and
DPT picked up a zig to 150 T. Just prior to firing, target zigged
an arbitrary 30 degree zig was cranked into TDC for a 77-30 port track. From
bridge angle on bow looked 30 port for a course of 090 T, 45 port track. Fire
was directed at overlapping targets, two being fired at the middle
ship and two at after (right) ship. All targets were bunched
within those limits, covering a total of about 8 degrees. It is considered
that at least two hits should have been obtained. Post-firing analysis indic-
ates targets were small, and torpedoes probably underran target. Targets
visible at 4000 yards from bridge, no moon, overcast.

Fire Control and Torpedo Data

Type attack - Second night surface attack on same convoy, using bridge TBT
bearings and radar ranges in which six Mark 18-1 torpedoes were fired. Cross
force 3 sec. in a 3000 yards, torpedo run 3500 yards for a 130-1
track, depth set 6 feet. TDC and DRT solutions checked for more than an hour.
When nearest ship flashed a challenge, fired three at him, then fired other
three at overlapping targets to the left of original target.

Just prior to firing, correct solution light on TDC went out be-
cause torpedo run exceeded 230 seconds. Range was reduced to 2500 yards, the
light came on, and firing commenced. No appreciable error was introduced,
all gyros being close to zero. The range at which correct solution
would re-light was obtained from a table, posted at TDC, whose arguments are
angle on bow and target speed.

Targets were visible from bridge at 4500 yards. Sky overcast,
no rain. Post-firing analysis indicates torpedoes underran targets.

Third night surface attack on same convoy, escorts, unidentified ships.
TBT bearings and radar ranges. Four Mk. 18-1 torpedoes were fired at
3 sec. torpedo run 2600 yards, track 82-84 port, depth set at 6 feet. TDC
solutions checked. Targets still looked like DD's or OJ's, since
abaft bridge with low stack. Angle on bow from TDC and TBT was 60,
so used 70 port. Fired two at left hand target and two
at right hand targets. Targets overlapping. Post-firing analysis indicates
torpedoes underran targets. Field width of two degrees was obtained on right
hand target at 3000 yards when angle on the bow was 80 port. This
300 feet supported the assumption of targets being DD's or OJ's, but
was probably in error. Continued attacks on the assumption that first attack
missed due to course error (was probably a short) and second attack missed due
to being challenged by escort.

TORPEDO ATTACK REPORT FORM

U.S.S. BOARFISH (SS327) TORPEDO ATTACK NO. 4 PATROL NO. 1

Time 0446 (H) Date 31 Jan. 1945 Lat. 14-55 N Long. 109-01 E
     2046 (Z)30th.

                       Target Data - Damage Inflicted

Description - Two 6500 ton (EU) engines aft tankers or freighters approx-
imately 450 feet long escorted by three DE type radar and probably radar
search equipped escorts. Ships and escorts sighted from bridge and
through periscope.

Target No. 1.
Ship probably sunk - One 6500 ton (EU) engines aft tanker or freighter. No
stack was observed through periscope at night. Target covered 6 degrees with
angle on bow 90 port for a length of 450 feet at 1500 yards timed torpedo run.

Damage determined by - One torpedo heard and observed by periscope to hit
amidships. When last seen 11 minutes after hit, ship was dead in water,
settling fast on an even keel, decks almost awash. The following night a
heavy, thick oil slick half a mile wide was observed two miles south of the
estimated position of our attack. Slick had a definite and continuous under-
water source at approximately 14-53N, 109-01E. From its source slick flowed
southerly with the usual southerly current along coast. Slick had a strong
diesel odor. No oil was observed between the beached target and source of
slick. It is considered that source probably was our target.

Target No. 2.
Ship Beached and Destroyed - One 6500 ton (EU) tanker or freighter, possibly
type 45 MKKNF, a new class cargo ship shown in ONI Weekly, Vol. III, No. 47,
Nov. 22, 1944, while burning on beach 36 hours after attack following
description obtained from beach trawling. A tanker having raked bow; cruiser or counter stern, poop ext-
aft with medium stack forward on poop, three or four ventilators aft of
stack; bridge about in middle between fore and mainmast; heavy cross tree on
mainmast. Length - approximately 450 feet by horizontal angle.

Destruction determined by - One torpedo heard and observed through periscope
to hit amidships. When target was last observed prior to evasion 11 minutes
after hit, it was headed towards the beach 3 miles away. At 1833 February
1st, 36 hours after attack, several distant explosions thought to be aircraft
bombs or internal explosions were heard. On surfacing half an hour later ship
was observed burning fiercely amidships and aft, flames being higher than mast,
burning fiercely amidships and aft, flames being higher than mast, smoke
obscuring details in the area. The next day we left the area with the fire show-
ing no signs of abating, after getting a good look.
     During the 36 hour interval from the time of the hit until target
was observed burning, the position was closely screened by two escorts of
the DE type. A pip seen on radar screen may have been target, but it was
difficult to discriminate between it and land. After the ship began to burn,
the escorts departed.

Fire Control and Torpedo Data

Type Attack - Conditions: Torpedoes forward expended. Tubes aft contained
four Mark 14-3A's with two more 14's in racks. Moon 3 days past full, slight
overcast, visibility 10,000 yards. Sea flat calm with gentle swells from
north.

Attack - Night submerged approach with convoy on course north hugging coast
and escorts to seaward on convoy's starboard bow, beam and stern. Submerged
ahead on track. Kept stern pointed towards targets and swung ship slowly
left toward shore.

With a range of 1500 yards, depth set 6 feet, fired two torpedoes
apiece at each of two 6500 ton (EU) enginos aft ships, gyros 175 degrees for
100 port track on first (left hand) ship, and gyros 200 degrees for an 80
degree port track on second (right hand) ship. Each ship received one hit
amidships observed through the periscope, and time at 65 seconds and 95
seconds after first torpedo was fired.

When contact was first made targets tracked at 9½ knots, and later
when alerted at 11 knots. TDC used 10½ knots to obtain hits at either speed.
Torpedoes were spread by periscope 1/6th length inside stem and stern. Post
firing analysis indicates a 9½ knot target speed. The third torpedo hit the
left hand ship at 56 seconds run, and the fourth torpedo hit the right hand
ship at 65 seconds torpedo run.

When last seen target No. 1 (left hand ship) was dead in water and
settling fast on an even keel, decks almost awash. Target No. 2 was heading
for the beach 3 miles away.

I. MINES.

Sighted a floating mine at 19-08N, 111-09E. Hit it with 20 MM fire
but it did not sink or explode. Considered it inert. Sighted a possible
decoy periscope with a mine attached to it at 20-42N, 121-44E. Handled it
as a submarine periscope and ran away, but later the lookout said he saw a
round rusty object at the bottom end of the periscope floating slightly
below the surface of the water. When this information was gleaned from the
lookout, we were far gone from the spot.

Sighted two more floating mines off INDO-CHINA coast at 2155 (H) 26
Jan., at position 15-10N, 109-05E. In process of evading an escort, so did
not fire on them.

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS.

No A/S measures encountered in first convoy. Don't believe they ever
knew they were fired upon. No pinging heard.

All other ship contacts were pinging on long scale, 14 kcs, 17 kcs,
and 18 kcs. The two cruisers had air cover.

The three escorts accompanying the two ships we hit were extremely
alert, indicating radar or radar search equipment. Guns were fired when we
felt we could not be seen. Use of AA projectiles is believed to be a new
wrinkle. Accuracy was poor. Some radar interference was seen on the SJ
scope but it never steadied on.

After the attack they were caught on the seaward side of us but soon
closed over and dropped 22 charges fairly close. They wasted none on
"embarrassing" drops. It is not believed that they ever had echo range
contact. There was a positive gradient of 2 degrees at 100 feet, depth of
water 180 feet, depth of evasion 155 feet. The evasion courses were in-
fluenced by the fact that deeper water lay to the east. However we tried
to keep them on the quarter. Eventual disposition seemed to be with one on
each beam and one astern with us heading seaward.

Turn counts of 160 and 180 were gotten on the escorts of DE type
tracking at 12 to 14 knots.

K. MAJOR DEFECTS AND DAMAGE.

Disabled QC-JK sound head by touching bottom at 87 feet avoiding a
junk.
Put a small dent in the stem by touching CHARR forward while man-
euvering to speak him in the open sea at night. Weather calm, clear, bright
moonlight. No damage to either vessel.

K. MAJOR DEFECTS AND DAMAGE - (continued)

Crystallization of two piston pins, one in each of the forward
engines, caused the pin to crack and break one inch from its middle. The
rough break gauged out metal from the piston pin bushing and connecting
rod piston pin bushing, thus depositing brass in the crankcase. This
evidence of brass located during routine crankcase inspections enabled
us to locate the trouble before extensive damage to the engine could be
done. The first casualty was found after arrival in Saipan; the second,
five days after departure from area. A new piston assembly required seven
hours for installation and no further trouble was experienced.

L. RADIO

NPM was copied with some trouble, jamming being noted, mostly on the
three lower frequencies. NPM faded on all frequencies from 0400 K to 0600 K
daily. The most effective jamming was encountered on 6045 and 4515 kcs. This
consisted of CW signals and broadcast programs which were very strong along
the eastern coast of Luzon. U.S. voice was also heard on 4515 in this area.
One ComSubPac serial was missed.

Jamming on VIXO was not so effective as on NPM but some jamming was heard
on 9250 and 4370 kcs. These two frequencies, however, gave the best reception
and were the main ones used in the area. The sked was copied through these
interferences, with no trouble as the jamming signals were CW and could be
effectively detuned. No serials were missed after the shift to VIXO. At one
time it was thought we had missed one serial until it was found to be a message
with the serial number in the setup immediately following the words "others
stop decoding". It is believed that some system of serials which would number
only messages of importance to all hands would be an aid in giving boats a
check that they have all the important information. At present, a boat patroll-
ing might worry over a missed serial which merely told a boat south of the
Barrier that his message wouldn't break. Conversely, a boat might not
become too alarmed over missing a serial which contained a recognition change.

Frequent attempts at jamming with CW were detected on NKN (Chunking), but
with the exception of one or two skeds the jamming was unsuccessful due to NKN's
signal strength doubling that of the enemy.

Occasional unsuccessful attempts at jamming were detected on the Wolf Pack
frequencies. CW was used exclusively. Communications with the Charr were sat-
isfactory while we were working with her, but we had no confidence that the
contact reports we sent to all hands on these frequencies were received by any-
one as no receipts were heard. The Wopaco code leaves much to be desired and is
not reliable. The two-character group construction is a notable weakness as
this requires the use of all possible combinations, so that a garble may go by
undetected. The time saved by use of two character groups is negligible and it
is felt that the aircraft or a similar code would prove more satisfactory. The
omission of many common terms such as beach, coast, shore, or a similar phrase
makes much spelling necessary with resultant loss of security.

Communications on ship-to-shore to VIXO were very satisfactory and no
trouble was encountered in clearing messages. In one case our message was out
on the sked twenty minutes after the first keying of our transmitter. Radio
Coonawara (VHM) was most helpful in relaying traffic to CTF 71 at times when
VIXO could not be heard. Jamming was present on the ship-to-shore frequencies
but was ineffective in blocking traffic to VIXO. Our worst trouble was clearing
a message to NPM, the keying of our transmitter
seemingly being the signal for numerous Japs to begin a random pounding away
on their keys. Over three hours were required to clear a hundred group message.

No casualties were experienced with the communications equipment. The
addition of the RBS receiver was very helpful, enabling us to copy NKN without
unguarding the Wolf Pack frequency. The RBS gave excellent results in copying
CW though it was somewhat inferior to the RAL for copying through jamming.

M. RADAR.
(1) SJ-1
SJ performance as a whole was good, though not consistent. Continuous
checking and adjustment was necessary to keep it operating properly. Casualt-
ies were minor, though numerous, total loss of time due to casualties amounting
to 17 hours, 24 minutes.

SJ operation was varied with visibility and area. Enroute to area it
was manned continuously day and night. In area it was manned at night, a
keying procedure first being used, transmitting for two minutes out of every
five and using the A scope as a 10 cm. search receiver the remainder of the
period. Later when no evidence was found of any RCM by the Japs or homing on
our radar, a continuous transmitting plan was used, searching on all PPI
scales. The steerable sweep was found very useful for searching the area
along the beach while 10-14,000 yards off-shore, to increase separation of
targets from land. This also proved helpful in tracking a convoy in obtaining
target separation at the usual tracking range of around 10,000 yards. The
20,000 yard sweep continued to be our basic one as it seems to be the happy
medium of large presentation and good coverage.

The high voltage keying on the transmitter proved useful at times,
but only occasionally were we able to pick up the transmissions of other
boats with the earphones installed and some difficulty was encountered in
reading signals from the A-scope. Signals were exchanged with other boats
at estimated ranges of up to 20 miles.

Contacts:
Furthest contact was island of LOMBOK at 130,000 yards.
AO at 23,000 yards.
Submarines from 7000 to 12,000 yards.
DE from 7000 to 15,000 yards.
DD from 9000 to 15,000 yards.
Small fishing boats 4000 to 6000 yards.
Small patrol boats 6000 to 8000 yards.
Planes 7000 to 18,000 yards; one contact at 25,000 yards.
Birds out to 5500 yards.

Casualties:
1. Most persistent trouble was a jumping of the range step at
10,000, 20,000, and 30,000 yards. This occurred only after the equipment
had been in use three or four hours and stopped when the equipment cooled
down again. All efforts to locate the cause were fruitless. After about two
weeks the condition disappeared.
2. The inductor LL.1 in plate circuit of bias generator, a tender
spare, was found open, but luckily this occurred prior to our arrival at
Saipan where it was renewed.
3. Magnetron was replaced twice, once because of low output, once
due to slightly lowered output and spurious modes of oscillation.
4. TR tube replaced twice.
5. Loss of intensity control of PPI twice due to fuse, F1 being
blown.

M. RADAR (continued)

(2) SD-5

The performance of the SD-5 was generally excellent, and reliable.
The set was operated continuously, night and day, while on the surface. Total
loss of time due to casualties was 12 hours, 10 minutes. The micro-second
manual keying feature, incorporated in the SD-5 was used to prevent homing
on the signal. The transmitter was keyed for a period never longer than ½
second, the keying interval was varied from ½ to 2 minutes depending on
circumstances. We had no indications of any plane homing on the SD using
this system of keying. There were, moreover, numerous SD contacts which we
watched go by, apparently unaware of our presence.

The persistent scope of this model proved an important feature. It
makes the short keying interval possible by giving positive indications of
targets even though keying for less than ½ second.

Contacts:

The great majority of plane contacts while on the surface were first
picked up by SD. Ranges obtained on the SD were generally excellent. Plane
contacts were made as distant as 42 miles. LOMBOK Island was picked up at
68 miles, lower land at 30 to 35 miles.

Casualties:

1. The major casualty, which accounted for the greater part of the
time lost, was the resistor network, R 914, 916, 920, 967, burning out. V 911
was also out. Cause for this is unknown.

2. The only other casualty of importance was both 2X2's in R.I. and
R 941, 946 in CRT high voltage supply network out.

(3) XCV

This equipment, essentially APR-1 gear with the addition of a
directional antenna system, a wave trap for positive frequency measurement,
an REB panoramic scope, and a high frequency receiver with a range of 1000-
3000 mc. was installed in New London, Conn. Good results were obtained on
DF'ing radar signals until a few days out of Saipan when the strain of frequent
dives proved too much for the antenna assembly which grounded out. When the
highest resistance reading got down to 10,000 ohms, we decided the gear was
useless in this condition, so by means of a jury-rigged T-connector, we
the equipment consisted of APR gear plus the wave-trap and REB. Good results were obtained in the low
frequency ranges and on the passage through LOMBOK were able to keep tabs on
the movements of the patrol planes looking for us when land 5 miles away made
the SD ineffective for all except very near us for targets. On this occasion
by watching the lobing effect on the SPA we were able to tell when he headed
in our direction before his signal strength changed much.

-43-

— page 49 —
M. RADAR (continued)

The high frequency receiver also did a turnabout on reaching the
area and was unable to pick up anything but our own SJ. This antenna, however,
had good waterproof connections, maintaining an infinite resistance to ground - possibly
an open circuit, but we had no way of checking this.

We decided to train the radio operators as the regular watch-standers on
this gear shortly after leaving Pan ama and gave them a course of instruction
under the close supervision of the RT. Thus by the time of leaving Pearl we
had eight watch standers who had no trouble distinguishing a radar signal from
the various SJ, SD, TBL, fan, ice cream machine and other spurious noise
indications which show up on the scope. In this connection the REB was useful
in that these "noise" signals always showed a broad band of frequencies on
the panoramic scope.

The wave trap is a very desirable feature as towards the end of the
patrol, the dial calibrations on the tuning heads were off as much as 20 mc.

(4) Radar Counter Measures.

With the exception of one possible case of DF'ing of our SJ no
enemy counter measures were encountered. During the approach on the convoy
30 Jan. AA shells were fired in our general direction at ranges which made
sighting improbable. The inaccuracy of the fire suggests that rough bearings
obtained by DF might have been used. Later in the attack we were more cautious
in the use of the SJ and were not fired on again. The SJ picked up interference
from the bearings of the escorts several times but this never steadied on us.
We believe that these escorts had 10 cm. radar as the XCV had no contacts at
the time of this SJ interference, making it unlikely that the SJ was picking up
harmonics of a lower frequency. This interference had a markedly different
appearance on the A-scope from that caused by SJ, the pips moving rapidly across
the scope, always from left to right, the pips themselves being broader and
closer spaced.

N. SOUND.

Sound conditions off the INDO-CHINA coast were good for listening.
No ping ranges were attempted. All gear performed satisfactorily and the JP
was outstanding in making initial contacts at long ranges. JP picked up
the screws of a light cruiser at an estimated range of 20,000 yards, 10
minutes before the top of its mast was sighted by periscope. On another
occasion the JP picked up pinging over an hour before convoy sighted, JP had
screws at 15,000 and QB picked up the screws at a range in excess of 10,000
yards.

Casualties were few and luckily the major one occured after our
last attack was completed. The JK-QC sound head shaft was bent and some of
the JK crystals shattered while operating in shallow water in order to observe
damage done to an enemy ship. The only other troubles encountered were a
grounded lead in the plug on the QB lead-in from the sound head which caused
a buzzing noise in the amplifier, and the slipping of the JP azimuth circle.

Both the slip rings on the QB and the counter-weighted cable-control
system for the JK-QC, installed at Pearl Harbor, were very satisfactory and
eliminated the old trouble of fouled leads. The slip rings especially proved
valuable in allowing continuous train of the QB. The QB was used when listen-
ing on the surface due to its simplicity of operation as lookouts were then
manning the sound gear. The JK was used for submerged listening to equalize
the load on all parts of the equipment. The frequency-search plan as recommend-
ed in the Sound Operator's Handbook was used continuously and is believed an
excellent one for picking up pinging.

V. REMARKS.

(a) Mark 18-1 torpedoes: Sixteen Mark 18-1's were fired for
no hits. Post firing analysis indicates torpedoes underran targets despite
four and six foot depth settings. Speed reduction for shallow settings as
directed by ComSubPac Conf. dispatch 091013 of November 1944 was used.

Torpedo #56082 developed a dead cell. Cell showed gravity below
1.100 and no voltage. Cell was clean and inspection did not indicate cause
of failure. Connector bars were cut using the engineer's small power ston-
ing machine and the cell jumped out of the circuit. On firing torpedo made
a normal run.

The charging panel located in after room was installed forward to
permit charging six torpedoes at once. Using three charging panels, the
weekly charge was given all 16 torpedoes on the same day, the torpedoes and
tubes also being routined. An average of 4½ hours was required to charge
each group of six.

Routining all torpedoes the same day offers the following
advantages:
1) The state of charge and battery temperatures of all torpedoes
is approximately the same resulting in similar performance.
2) Lookouts in forward room cannot sleep for one 12 hour
period each week; otherwise they are not disturbed.

(b) In accordance with ComSubPac verbal instructions, a special
report on Mark 27's is being submitted to him via the chain of command.

(c) A special report on the XCV radar search gear is likewise
being forwarded to ComSubPac via the chain of command. In brief, the XCV
is lacking in pressure-proofness, corrosion resistance, and physical
ruggedness. This applies to the antenna array only, as the search receiver
is the standard APR receiver and very good. It is, however, an aircraft
unit, using 28 volt DC power supply, and not tailored for submarine use.
Although it is a fine idea to know the general direction of a radar signal,
the tactical situation will probably clearly indicate the direction in the
case of surface vessels, and in the case of a plane it is not so important.
I feel that search gear that will effectively cover all frequencies auto-
matically, simply and thoroughly, is more valuable than having the
directional feature on a limited band. We had evidence of enemy 10 cm.
radar on the night of 30 January, but as our high band antenna was not work-
ing, we were unable to analyze it.

(d) The SD-5 radar is excellent. We are inclined to the opinion
that if planes are up there we want to know that fact. We had no evidence
that split-second radar keying attracted any planes. We do have evidence that
closing planes were present, allowing us to dive before being attacked or
even detected.

V. REMARKS (continued).

(e) The statement of Hamilton, C.L., ARM2c, survivor picked up
by CHARR from ditched PBM 206 is forwarded as enclosure C to this report
to Commander Submarines, Southwest Pacific only, for his disposition. He
was a cheerful and welcome shipmate, but still prefers aviation to submarin-
ing.

(f) A word of appreciation is due the tireless efforts of the NDRC
engineers under Mr. Fred Arndt at Pearl Harbor in designing and installing
the slip-ring assembly on the QB sound head; an ingenious pulley and counter-
weighted spring arrangement on the QC-JK sound head cables; and on the nice
fitting of the No. one periscope TBT which was used a great deal and which
we have come to like very much. It repeats true and relative bearings at
plot, and conning tower, and relative bearing at the TDC. When the lubbers
line is accurately grooved and the assembly well adjusted, we feel the
system is absolutely reliable. However, the least bit of carelessness in
assembly and adjustment will bring continual grief.

(g) I feel it pertinent to remark, upon bringing a newly built ship
out to join a seasoned fleet, that the construction, design, and workman-
ship of the Boarfish has been beyond reproach in all respects, and the
methods of procurement and the training of officers and enlisted men has
been reliable and sound. It is hoped that the Boarfish organization will
be disturbed as little as possible by transfers.

FIRST ENDORSEMENT to
USS BOARFISH (SS327) -
Report of First War
Patrol.

From: The Commander Submarine Squadron EIGHTEEN.
To: The Commander in Chief, UNITED STATES FLEET.
Via: (1) The Commander Submarines, SEVENTH FLEET.
     (2) The Commander SEVENTH FLEET.

Subject: U.S.S. BOARFISH (SS327) - Report of First War Patrol.

1. The first patrol of the BOARFISH, the sixth for Commander
R.L. Gross as such, conducted in the SOUTH CHINA SEA area, was of 52
duration, twenty days of which were spent in the assigned area. Patrol was
terminated due to virtual expenditure of torpedoes.

2. Four contacts were made worthy of torpedo attack. Two of these
were developed into attacks, two could not be closed.

3. Attack No. 1. On 21 January a night surface attack was made
on a convoy of five or six small ships. Six Mk. 18's were fired on an 80°
track, 1500 yard torpedo run, small gyros, depth set four feet at three over-
lapping targets. No hits resulted, probably due to a last minute zig of the
targets.

Attack No. 2. This was a night surface attack and followed
attack number one on the same convoy. Six Mk. 18 torpedoes were fired on
about 120° track, torpedo run 3500 yards, gyros small, depth set six feet
at two overlapping targets for no hits. Solution was checked accurately
for more than an hour. Torpedoes probably underran targets or dispersion of
Mk. 18's at 3500 yards range was too great to hit the small targets. Firing
was hurried due to a near escort challenging.

Attack No. 3. This was a night surface attack and the third
attack on the same convoy. Four Mk. 18 torpedoes were fired on an 80° track,
2600 yards torpedo run, gyro on 17° R, depth set six feet, at two overlap-
ping targets for no hits. Torpedoes probably underran targets. It is regretted
that such aggressiveness and dogged determination displayed on these attacks
was not rewarded with some damage to the enemy.

Torpedo Attack No. 4. On 30-31 January a night periscope
attack was made on two escorted 6500 ton AK's (EU) or AO's. Two Mk. 14-3
torpedoes were fired at each ship. Torpedo run on first AK was 1500 yards,
gyros were small, track 100° and depth set six feet; on second AK torpedo
run was 1700 yards, gyro 20° L, track 80°, and depth six feet. One hit was

obtained in each AM. When last seen the first target was settling with
decks awash. The second target was headed toward the beach. The BOARFISH
was forced to take evasive action in 100 feet of water and was depth charged
with only minor damage. This attack was completed after being driven off by
radar equipped escorts, subjected to shrapnel fire and forced to dive. This
chasing escort. This did not deter the BOARFISH from making an intelligent
estimate of the situation which was rewarded by a successful attack after
another end around. After the above attack the BOARFISH tried unsuccessfully
to close the beached ship to insure destruction. Thirty-six hours later the
ship was noted to be burning furiously and the attack was abandoned as destruc-
tion was assured.

4. This patrol was characterized by excellent and thorough area
coverage and was extremely aggressive. In addition the BOARFISH returned an
aviator previously rescued by the CHARR.

5. The BOARFISH presented a neat and clean appearance upon return
from patrol and a high state of morale is reflected in the attitude of officers
and crew. The Squadron Commander welcomes the BOARFISH to this area and
heartily congratulates the officers and crew upon the completion of their
first patrol and for the damage inflicted upon the enemy.

From: The Commander Submarines, SEVENTH FLEET.
To: The Commander in Chief, UNITED STATES FLEET.
Via: The Commander, SEVENTH FLEET.

Subject: U.S.S. BOARFISH (SS327) - Report of First War
Patrol - Comment on.

1. The First War Patrol of the BOARFISH, under the com-
mand of Commander R. L. GROSS, U.S.N., was conducted in the SOUTH
CHINA SEA off the coast of INDO-CHINA.

2. On 21 January, at 0311(H) BOARFISH made a night sur-
face radar attack on a group of six ships, three of which were es-
corts. Six torpedoes were divided amongst three ships from a fav-
orable position, range 1,600 yards, but no hits resulted. At
0521 the same group was again attacked, and six torpedoes were
fired regardless of the fact that one escort was already challeng-
ing BOARFISH with a white light. No hits. With unshaken deter-
mination BOARFISH attacked this group again with four torpedoes
at 0612. Again, no hits. The Commanding Officer is of the opin-
ion that torpedoes ran under the targets.

3. On 31 January, following a long and very skillful
night chase, during which BOARFISH was driven off by enemy gun-
fire after being detected by his SJ interference, he very cleverly
took station well ahead of the convoy and dived to periscope depth
in order to pre-warn enemy analysis of radar. At 0446 four tor-
pedoes were fired at two targets; one hit sank the first, and one
hit damaged the second to such an extent that it had to be beached;
where the Fourteenth Air Force planes completed its destruction.

4. The award of the Submarine Combat Insignia is author-
ized for this Patrol.

5. The Force Commander congratulates the Commanding Of-
ficer, Officers and Crew of the BOARFISH upon their determined
conduct of this patrol during which the following damage was in-
flicted upon the enemy:

A. PROLOGUE.

Arrived FREMANTLE, W.A., upon completion of first war patrol
on 15 February 1945. Received normal refit by Submarine Repair Unit
and ComSubDiv 301 relief crew in EURAYLE. Major work accomplished
consisted of: overhaul of main engines and auxiliary; redesign
and leak-proofing of XCV radar search antennas; installation
of Mark 4 (ST) periscope without electronics; installation
of small DRT in conning tower (time did not permit hooking this up
electrically); and reducing propeller and shaft noises by changing
propellers and re-wooding. The ship was in good shape, and credit is
due Commander Jack Martin and CSD-301 relief crew for the clean and
shipshape condition they maintained during refit.

Lieutenant J.R. COPELAND, USNR, executive officer, detached with
regrets. Commander H.M. LINDSAY, Jr., USN, reported on board as PCO,
and Lt.(jg) W.H. RATHGEBER, USNR, reported on board as electronics
officer.

Five days training, including one day of special exercises, one
day of torpedo firing and one day and night of convoy exercises.
Captain Jesse L. HULL, training officer. Did not require degaussing.
Ready for sea 11 March 1945.

         gallons of fuel oil from her. Oil barge still on the beach from
         storm last month.
1530 (H) Underway from alongside COUCAL for LOMBOK Strait.

1820 (H) Sighted U.S. Submarine, exchanged challenges and calls with PINTADO,
         southbound, on SJ key.

                                        17 March 1945

0926 (H) Sighted peaks of LOMBOK and BALI over 100 miles away.
1100 (H) Dived to transit LOMBOK at midnight.
1902 (H) Surfaced.
2200 (H) In south approach to LOMBOK, very faint 201 mgc XCV contact, too
         weak to analyze.
2320 (H) Two small patrol boats on SJ radar at 4000 yards and in sight at
         3800 yards, running slow speed northerly. Changed course to the
         right to leave them on our port beam at 3800 yards. No action
         taken. These were the only sign of enemy activity. As the moon
         was down, did not use the SD radar, but depended on the XCV
         radar receiver to warn of planes. Used SJ once every five
         minutes.

                                        18 March 1945

0625 (H) Sunrise. Dived to approach and transit southern passes of
         KINGELAN Islands. Several sails sighted this day.
1913 (H) Surfaced with KINGELAN Island in the northeast 14 miles, entered
         JAVA Sea, took westerly course 30 miles north of MADURA Island
         at moderate speed to patrol one day submerged off SURABAYA.
         View of a reported contact and the area was known to be vacant.

                                        19 March 1945

0500 (H) Searchlight elevated high from direction of SURABAYA.
0540 (H) SJ radar contact at 9000 yards. Just getting light in the east.
(S/C #1) Tracked at slow speed, southerly course. Position 6-25S, 112-59E.
0602 (H) Range 8000 yards, getting too light, dove.
0630 (H) Contact appeared to be a patrol boat, somewhat similar to AM-1
         class of about 800 tons, not pinging. We drew away from him.

B. NARRATIVE (continued)

19 March 1945 (continued)

0712 (H) Pinging heard very faintly the south in the direction of
           SURABAYA. We are about 10 miles north of suspected mine fields.
           If they go to MAKASSAR, we are in good position.
0752 (H) Float-type plane (RUFE) circling to the south in the direction
(A/C #1) of pinging.
0900 (H) Pinging, plane, and patrol boat out of sight. Believe a sortie
           was made from SURABAYA but that they hugged the coast, and that
           the patrol boat had nothing to do with it.
1913 (H) Surfaced. Sighted searchlight again, still directed upward and
           sweeping. Proceeded at moderate speed westerly, looking for patrol
           boat seen this morning and heading for Cape MANDALIKA as a
           likely spot to intercept a reported contact. Several small sails
           sighted and avoided.
2335 (H) Sighted BAWEAN Island to the north about 30 miles away.

20 March 1945

0218 (H) In position approximately due east of Cape MANDALIKA, patrolled
           on station. About 8 miles from coast of JAVA.
0610 (H) Dived for the day. Sighted several small sailing vessels.
1918 (H) Surfaced. Proceeded west still looking for something, about 10
           miles north of JAVA coast.
2307 (H) Very faint XCV contact over wide band. Could be thunderstorm we
           are passing through.

21 March 1945

0018 (H) Sighted correctly lighted hospital ship to the north, on an
(S/C #2) easterly course at 13 knots. He was passing between the KARIMOEN
           Islands and JAVA probably out of BATAVIA for SURABAYA. Position
           06-20S, 110-30E.
0300 (H) Have overlapped reported contact about 3 hours and entering HMS
           TELAMACHUS' area, abandoned search, set course to the north for
           KARIMATA.
0335 (H) XCV contact at 2085 megacycles, sweeping part of the time, some-
           time steady on us. Possibly British submarine radar. Not listed.
1021 (H) Sighted low-flying float plane crossing astern at about 12 miles.
(A/C #2) Not on SD radar. C.O. on the bridge held up the normal dive to
           observe. Plane crossed our 17 knot wake but continued his east-
           ward course until out of sight at about 20 miles.
1301 (H) Dived to approach southern entrance to KARIMATA undetected. ROCK
           was hit by a dud torpedo near here two days ago.
1935 (H) Surfaced. Half moon at zenith, flat sea, entered KARIMATA Straits.
           Several occasions of a pip on PPI plotted stopped at 1000 to
           3000 yards. Could be anything. Avoided each one.

22 March 1945

0130 (H) Moonset.
0153 (H) Picked up KARIMATA Island on schedule at 85,000 yards.
0607 (H) With ROETOE 15 miles to the northeast, dived for the day
           primarily to avoid enemy submarines.
1943 (H) Surface running. More phantom pips all night. Sea glassy smooth. Set
           course north to pass between TAMBELAN Islands and BORNEO, heading
           for reported contact between South NATUNA and Great NATUNA.

23 March 1945

           Surface running. Checked out some of these phantom pips as birds.
           Others could not be identified. Sighted several sailing vessels.
1347 (H) Sighted smoke which developed to be one small engines-aft coastal
(S/C #3) AK with four escorts, half way between South NATUNA and Great
           NATUNA, headed northwest. We are in TUDOR'S area. Pulled ahead
           trying to track, but even with hull fully visible through high
           periscope could not get him on the radar.
1449 (H) With an angle on bow close to zero and range estimated 15,000 yards,
           dived for attack. Position 03-30N, 108-15E.
1536 (H) Target at 8000 yards seems to be a decrepit looking coastal AK
           with a slight port list. Stack nearly as high as mainmast, riding
           very light. About twelve feet of red-lead and rust showing between
           load water line and the water level. Number 67 on his port bridge
           panel. One PC escort ahead, angle on bow zero, pinging, turned
           out to avoid. He passed down the port side at 1500 yards. Range
           to target now 3800 yards, angle on bow 20 port. Just starting
           to turn in again when we noticed port beam escort showing zero
           angle on the bow, range about 2500 yards, relative bearing 270.
           Sound reported then that he was on short scale pinging. This
           escort was similar to our converted yacht type - two masts of
           equal height, low freeboard, one squat funnel with white bands
           painted on it. Another escort was seen following astern and one
           on the other (starboard) flank, both of the converted yacht type.
           Tubes were flooded, depth set 4 feet, but decided against firing
           at the target at that range (about 3000 yards). He looked too
           small and high out of water to be a good shot, and the whole
           setup did not look good. Why four escorts for an unloaded tramp?
           Speed of target checking at 8 knots. Rigged for depth charge and
           escort at 2000 yards on our port beam, angle on the bow zero,
           Speed at 2/3 speed to avoid. 270 feet of water available.
1603 (H) Passing 130 feet received first of fifteen close depth charges,
           the first of which pushed us up to 90 feet. Leveled off at 250
           feet and took a retiring course at 2/3 speed. No other offensive
           action was taken by the escorts. Believe he had sound contact but
           was primarily interested in reaching port. He might have been un-
           sure of his contact, but his charges were close.

                                                                Caused us the following damage: opened fuel oil vents in after

                                                                pump flow meter off the bracket; flooded out bridge diving alarm
                                                                and telephone call buzzer; broke off both port XCV low-band dipole
                                                                insulators, dropping one dipole on deck; loosened all deck hatches
                                                                one-half to one turn; set up a click and crunching noise in
                                                                port reduction gear; flooded out both sound training motors later
                                                                due to leak at tank top flange; and jarred loose cork and chipping

                                                                all spilled; azimuth scale of JP shaft knocked loose.
1753 (H) Periscope depth, all clear, pinging faintly audible to the north-
                                                                west. Believe they went into Great NATOLNA, where they would
                                                                arrive about 1900.
1943 (H) Surfaced. Cleared area, proceeding north to our area. We hope
                                                                TUDOR will have better luck if and when they leave port. Started
                                                                repair work.

                                                                24 March 1945

0041 (H) Both air conditioning plant back in service. A difficult up-
                                                                side-down silver solder job neatly accomplished on each. Running
                                                                on the starboard shaft only while the port reduction gears are
                                                                inspected.
0326 (H) Moonset. Inspected topside. XCV low and medium bands read 12,000
                                                                ohms to ground. Disconnected and placed out of commission for
                                                                remedial of patrol. Hooked up standard APR antenna to receiver.
                                                                From now on it will be called APR. This was very disappointing
                                                                as the same thing happened on the last run, and we thought that
                                                                this time with many design changes, it would hold up. It must
                                                                be stated, however, that those depth charges were closer than
                                                                average. The search for a rugged directional antenna must continue.
0641 (H) Dived about 30 miles north of Great NATOLNA for the day. Made
                                                                level tests on port shaft after inspection of gear showed
                                                                no unusual tooth condition; pulled both sound training motors
                                                                installed lathe motor at QB position. Port shaft much noisier than
                                                                when we left Perth this time, but not much noisier than when we
                                                                arrived Pearl or Perth. Decided it was safe to continue patrol.
                                                                The subject of decibels is a complicated one, and we found
                                                                comparisons to previous data difficult.
1929 (H) Surfaced, continued on northerly course for patrol area C-2. Seas
                                                                building up.

                                                                25 March 1945

0858 (H) Sighted U.S. Submarine at 10,000 yards. Exchanged challenges
                                                                and calls with HAWKBILL, south-bound.
2140 (H) After considerable SJ interference, exchanged challenges and
                                                                calls with PAMP.NITO, bound for PEARL.

B. NARRATIVE (continued)

25 March 1945 (continued)

2200 (H) QC-JK training motor re-installed and working, using QB armature for
          it. Continuing attempts to repair QB motor, as the armature is
          not just right for the job, it having four poles instead of six.

26 March 1945

1254 (H) SD contact at 12 miles, lost it at 14 miles. Slowed to one engine
(A/C #3) due to heavy head seas.

27 March 1945

Enroute area on northerly course, one-engine speed, head seas.

28 March 1945

0200 (H) Entered area C-2, unable to raise GURNARD and HAMMERHEAD.
0758 (H) Sent message to CTF 71 about being unable to raise above
0806 (H) Dived for submerged patrol on 100 fathom curve until other boats
          are located.
0840 (H) QB sound head, after much testing, finally reads zero through the
          head, out of commission for rest of patrol. JK-QC and JP
          are all right.
1932 (H) Surfaced.
2039 (H) Cloudless sky, full moon, SD contact at 10 miles, closed to 4 miles,
(A/C #4) dived. No APR contact. Our gear is very unreliable since the depth
          charging.
2100 (H) Surfaced.
2117 (H) SD contact 14 miles, opened and lost at 16 miles. Closed beach,
          searching for reported convoy. No contact with our other two boats.
          Probably same plane.
2225 (H) SD contact 9500 yards, started tracking. Battle stations. Four or
(S/C #4) five pips on PPI, closest one now seen at 4800 yards. Full speed to
          open out. Position 14-18N, 109-20E.
2250 (H) Two green Very stars. Escort chasing us now just visible. Full moon,
          calm seas. He is making 16 knots.
2252 (H) Angle on the bow 30 port, range 4200 yards steady, dead astern. Escort
          firing his gun.
2253 (H) Fired 3 Mark 14 torpedoes aft, small left gyros, torpedo run 3200
(Attack #1) yards, depth set 4 feet. (Target looked like a PC of the CHIDORI class)
          overheard but could not slow down to fire. Speed at firing was 18
          knots.
2255 (H) No hits; gun firing getting close. One ricocheted overhead, one landed
          50 yards on port beam. (Target looked like a PC of the CHIDORI class)
          Started reload. 250 feet of water. Escort came over pinging.
2256 (H) Dived.
          Observed at periscope depth through the Mark 4 night periscope.

28 March 1945 (continued)

2313 (H) With range full field, probably 900 yards, angle on the bow 90 star-
          board, he slowed to listen. Looked like a PG or DE. Didn't hear
          180. Only one torpedo relo ded, reload stop ed for 'silent running.
          Didn't a re risk a single shot. JK head on him, JP reported another
          one ahead. Other escort seen closing, also a PG or DE. Both worked
          back and forth, pinging and listening, speeding up and slowing down.
          It was great comfort to be able to see the large angles on the bow when
          the range was close. If they had got on us, however, it would have been
          uncomfortable. Now boxed between the two, all of us going the same way,
          them astern at 1500 yards, so we turned completely around, and rapidly left
          their return. They dropped no charges.
2351 (H) Secured from battle stations.

29 March 1945

0009 (H) Surfaced. Began chase at 3-engine speed, charging. Estimated convoy
          speed as 10 knots. They are well ahead. Still cannot reach our other
          two boats. As we were in the south end of the area, they could be in
          good position. Sent contact to VIXO.
0042 (H) SD contact at 2 miles, quickly corrected to 12 miles, which was land.
0223 (H) Heard about 11 distant explosions.
0301 (H) Interference on SJ scope; tried challenge, no luck.
0333 (H) Put fourth engine on propulsion. 10 cm. interference very strong, no
          reply to challenge. Too bad our PR is not working.
0412 (H) Picked up target at 12,000 yards, bearing of target and no doubt
          agree. Seen through glasses, identified as escort. He was forcing
          on us with his radar, not his PR, and gradually forcing us to seaward.
          Convoy not on screen, but assumed to be almost abeam now on an MNW course.
          We are forced to a NE course by this escort. Continued making what we
          can to the northward.
0529 (H) Escort at 10,000 yards abeam, both of us well to seaward, getting light
          in the east, abandoned chase. They should reach TOURNI this morning.
0609 (H) Dived for the day, escort in sight at 12,000 yards to shoreward.
0616 (H) Heard an explosion, possibly a torpedo hit.
0627 (H) Heard total of 31 depth charges the next hour.
1004 (H) Heard 88 distant explosions, up to 1130, thought to be aircraft bombs.
          air strike due this morning. Set watch on aircraft voice (4475) and
          Gibson Girl (500), listened on SD antenna for 25 minutes of each hour.
1555 (H) Sighted U.S. submarine nine miles away.
1635 (H) Surfaced to talk to him.
1706 (H) Spent an hour talking with H.M.S.D via hand signal light. Found
          out that a dispatch on 2 March had directed use of alternate wolf pack
          frequencies. He had been using primary and had heard primary a week
          ago to the south. Dispatch not located on board. Very relieved to
          find H.M.S.D. Tested alternate frequencies. Tested VHF, found un-
          usable at 300 yards.

assigned patrol stations. Delighted to hear he sank a DD this
morning, maybe the one that had pushed us to seaward on our end-
around. Parted company with HAMMERHEAD, took up patrol station
off Cape S.HOI.
1940 (H) Sighted two red lights to the north, eventually identified as a
(S/C #5) hospital ship, tracked at 15 to 17 knots, on southerly course.
Position 14-57N, 109-40E. Some 10 cm interference from his
direction, but could have been GURNARD, whom we had contacted on
wolf pack frequency.
2000 (H) Hospital ship slowed down.
2030 (H) Plotted H stopped. We began to circle him at about 10,000 yards.
Still occasional SJ interference. Identified as passenger-freighter
looking ship of about 10,000 tons. Green band not
illuminated, but red cross very bright on funnel and red cross on
foremast. Running lights were correct. No other ships sighted,
no pinging. Closed to 8000 yards for better look. Full moon, no
clouds, calm sea.
2200 (H) He finally resumed his 15 knots to the south, steady course. We
searched hard for reasons to believe him violating HAGUE rules,
but could not pin any down. Only a boarding party could do it,
and although we all have toyed pleasantly with the idea, it appears
too impractical from a submarine. Our communications between each
other are difficult enough. It could run into a twelve hour job
telling a Jap in international code to send over a boat. Hostages
would probably be in order. We resumed patrol.

30 March 1945
0054 (H) SD contact 6 miles, closed to 4 miles, dived. Still full moon
(A/C #5) overhead, no clouds, calm sea.
0127 (H) Surfaced. This plane may have been brought out by the hospital
ship. We must have been in clear view of the ship. Perhaps they
were hoping we would close them. Such an A/S trap could easily
be devised by the Jap mind.
0620 (H) Dived for inshore patrol. Tried working GURNARD and HAMMERHEAD at
50 feet with the SD antenna. No luck. However, we could hear the
pack to the north, presumably on the surface. We three are listen-
ing on the even hour for 10 minutes when we are submerged.
1444 (H) Sighted plane heading north. Possibly a B-25, PB2Y, PB4Y, or EMILY,
(A/C #6) about 8 miles.
1938 (H) Surfaced. Night patrol 10 miles off shore, near Cape S.HOI. Several
sails sighted, considerable SJ interference. We use a 5 minute
sweep interval on the SJ, the other 4 minutes being used as a
search receiver only.

31 March 1945
0619 (H) Dived for submerged patrol 5 miles off Cape S.HOI. Many sails in
sight all day.

31 March 1945 (continued)

1938 (H) Surfaced.
2255 (H) COD and 2 lookouts sighted a periscope on starboard bow in the bright
moonlight. Maneuvered to avoid and reported it on wolf pack circuit.
Position 14-45N, 109-19E(off Cape SAHOI).
2300 (H) Shifted clocks to 2400 (I). Opened out from coast while moon was
bright, also to observe an AH due to pass tomorrow morning.

1 April 1945

1000 (I) Sighted smoke on the horizon to the north. Tracked.
(S/C #6)
1007 (I) Small port angle, range 15,000 yards. Dived.
1026 (I) Ship identified as correctly marked AH, the TAKASIGO MARU. Position
14-47N, 110-04E, 62 miles off the coast.
2010 (I) Surfaced.

2 April 1945

0624 (I) SD contact at 9 miles, closed to 4 miles, dived. Ten miles off shore,
(A/C #7) closed for day's patrol. Several sails, all small.
2038 (I) Surfaced. Avoided many small SJ contacts both birds and native craft,
all inside of 3000 yards. Patrolled 10 miles off shore till moon
became very bright, then opened coast, to return at diving time.

3 April 1945

0610 (I) Lookout sighted periscope on port bow. Not confirmed, but avoided.
Bright waning moon 5 hours high. Position 14-45N, 109-12E. Did not
report this one.
0636 (I) Dived for the day. Many fishing boats and floating fish markers
(sticks with a flag on them).
2032 (I) Surfaced.

4 April 1945

0210 (I) Ran full power for one hour to test port reduction gear which has
remained at high noise level since the depth charging on 23 March.
Satisfactory but noisy.
0550 (I) Dived for the day. Patrolled 5 miles off S.HOI.
2022 (I) Surfaced. HAMMERHEAD departed area. Gave GURNARD more scope to the
south and we took up patrol station off NUOC.

5 April 1945

0618 (I) Dived for the day.
1302 (I) Heard nine distant explosions. Depth charges or aircraft bombs.

6 April 1945
0657 (I) Dived for the day.
0921 (I) Sighted wreck of a ship, aground at 14-10N, 109-12E. Closed beach
           to 2 miles for close reconnaissance, but currents and small boats
           interfered too much, so opened out to five miles again.
2023 (I) Surfaced. SJ contact 16,000 yards shoreward, plotted stopped 2000
           yards off shore. Could be land, a wreck, or a decoy. We did not
           close.

7 April 1945
0615 (I) Dived for the day off NUOC.
2036 (I) Surfaced.

8 April 1945
0658 (I) Dived for the day off NUOC.
1418 (I) Sighted small launch through periscope, north-bound.
(A/C #8)
2027 (I) Surfaced. Experienced peculiar temperature variations during the day;
           as much as 7 degree change from 1600 to 1700. Seas have been dead
           calm for many days. We are 5 miles off shore.

9 April 1945
0128 (I) Rendezvous with HARDHEAD (CTF 71) and sent boat over with mail.
           Received mail for us, GURNARD and FLOUNDER and radar parts.
           Borrowed four movies.
0219 (I) With the boat half-way back, SD contact at 9 miles, closed to 3 miles,
(A/C #9) then we did HARDHEAD, leaving boat between us. Executive Officer
           said it was a pretty lonely feeling.
0234 (I) Surfaced, recovered boat. Plane was seen flying high overhead, north-
           bound. Probably a transport.
0350 (I) Fell in with GURNARD, sent over mail and radar parts via boat. Also
           FLOUNDER mail, as GURNARD was working to the north.
0612 (I) Dived for the day. Patrolled 5 miles off NUOC.
2029 (I) Surfaced. Proceeded north to point off TIN QUAN. Conducted special
           exercises.

10 April 1945
0347 (I) Special exercises completed.
0650 (I) Dived for the day off Cape SAHOI.
2024 (I) Surfaced.

11 April 1945
0652 (I) Dived for the day 5 miles off Cape SAHOI. Closed to two miles for
           close look. Nothing but more sailing vessels, all small.
1145 (I) Sighted B-25 north-bound. B-25 shipping sweep due this noon. Set
(A/C #10) watch on 4475 kcs and listened occasionally on SD antenna at 50 feet.
2025 (I) Surfaced. Continued listening watch on lifeguard and also on 500 kc
           all night. No signals and no reports of planes in trouble.

12 April 1945

0655 (I) Dived for the day off CAPE SAHOI, CULIAO to the south of NUOC.
1516 (I) Sighted plane through periscope, not identified, single engine, high
(A/C #11) wing, flying south along shore.
2026 (I) Surfaced.

13 April 1945

0002 (I) SD contact 8 miles, closed to 4 miles, dived.
(A/C #12) Dark moonless night, no APR contact.
0012 (I) Surfaced.
0554 (I) Dived for the day off S.HOI. Have seen nothing except fishing boats
day or night. Moon is right for night surface attacks. Much
activity in JAVA Sea but none at all in South China Sea. Possibly a
result of our landing the other day on OKINAWA, but it would seem
that the Japs would be in a hurry to move shipping north before
OKINAWA becomes a BLUE base.
1200 (I) Gave first cholera shot to all hands, and started ATABRINE pills.
2027 (I) Surfaced. Entire ship's company profoundly shocked to hear news
broadcast of President Roosevelt's sudden death.

14 April 1945

0930 (I) Sighted three H.P.S at four miles towards the shore flying southwest.
(A/C #13)
1446 (I) Heard 10 distant depth charges. Nothing but land in sight at about
eight miles.
2040 (I) Surfaced. Closed coast just north of TOURANE. New moon one hour high
in the west. Sea flat calm, slight surface haze, bright starlight
night.
2228 (I) Commenced special exercises.

15 April 1945

0050 (I) Lookout reported torpedo wake stretching from both quarters astern.
We were making 10 knots on one engine, having just speeded up and
turned 70 degrees left to place a 1700 yard SJ contact on the star-
board beam. Night was too dark to see details through the Mark 4
periscope. Believe wake seen was our own after the turn. In fifteen
fathoms five miles off TOURANE.
0655 (I) Dived for the day, patrolling wide of CULAO CHAM south of TOURANE and
investigating the small island HON ONG which appeared to be deserted.
2037 (I) Surfaced. Returned north of TOURANE.

2038 (I) Surfaced.
2227 (I) APR contact very weak, 95 megacycles, 500 p.r.f. Possibly C.O.
         B.T.N.G.N forty miles away. Our APR seems to be improving for no
         good reason.

18 April 1945

0000 (I) APR contact 197 megacycles, 1000 p.r.f. very weak. Disappeared
         shortly.
0650 (I) Dived for the day off shore just north of TOURANE. Avoided many
         fishing boats.
2040 (I) Surfaced. Night patrol 10 to 15 miles off shore. Many SJ contacts
         at 1200 to 5000 yards, believed to be sailing vessels and fishing
         boats, all lot stopped or slow speed.

19 April 1945

0352 (I) Commenced conversion of No. 3, 4, and 5 fuel ballast tanks. Took
         one hour.
0602 (I) Dived. Opening coast preparatory to departure this evening.
1227 (I) Surfaced.
1320 (I) Sighted plane astern at 8 miles, closing. Dived.
(A/C #15)
1400 (I) Deep dive for test.
1630 (I) Surfaced.
2000 (I) Departed area in accordance with Opord.

C. WEATHER.
FREMANTLE TO AREA: - Gentle variable winds, never over 12 knots, clear skies,
IN AREA: - Except for two days, the weather was annoyingly perfect. Glassy
seas, zero wind, cloudless skies became monotonous. They also
brought the hundreds of "ghost" pips on the radar. Each
had to be treated as a mine or periscope however.
AREA TO SUBIC: - Fifteen knot winds from the southeast, clear and warmer.

D. TIDES AND CURRENTS.

Very heavy tide rips with a .6 knot southerly current was encountered in
LOMBOK Straits about 2300 17 March.

Currents along the INDO-CHINA shore were variable, indicating the turn of
the monsoon. However, no winds were experienced and the general drift was
.5 to 1.0 knots to the southeast.

E. NAVIGATION AIDS.

No navigation lights were burning, although several were passed close
enough to have been seen, even if burning dimly.

Peaks, tangents, and islands cut in well by periscope and radar.

LORAN was carried, and poor fixes obtained off the north Australian
stations, probably due to their unfavorable angle. We hope that Philippine
loran charts will soon be available for the South China Sea area.

TACTICS: - Night surface attack using radar ranges and TBT bearings, full moon, light overcast, visibility 8000 yards. Shot three torpedoes from stern tubes at 4000 yard range, depth set 4 feet, torpedo run 3200 yards, 50 port track, letting natural dispersion take care of spread. DRT and TDC solutions checked well to speed and course. Bridge estimate of angle on bow confirmed course. Firing his guns was done from surface to force target to come at us and abandon chase so that we could continue end-round on convoy. There were no hits and his gunfire became splashes 100 yards astern, so we dived and lost out on convoy.

I. MINES.
No mines sighted, and no sweeping or laying operations seen.

J. ANTI-SUBMARINE AND EVASION TACTICS.
During the approach on the single small maru with four escorts on the
afternoon of 23 March, one escort picked us up with his echo ranging
at over 2000 yards. Water was slightly ruffled, occasional white caps. He delivered
thirteen charges, but never regained contact. We evaded at
250 feet of water, with a four degree negative gradient at 150 feet.

During the approach on the convoy the night of March 28, one escort picked
us up on his 10 cm. radar, closed to 400 yards before we completed our turn and
had four engines on. He fired about eight slow rounds of 3 or 4 inch, each
closer than the last. When we fired three torpedoes at him he did not swerve
nor stop firing so we dove. He came as close as 900 yards, pinging and listen-
ing while we were at periscope depth watching him. He had the appearance of a
PG. He was aided by a second PG and neither of them picked us up at 900 to 1500
yards, either pinging or listening. Evaded at periscope depth, B/T not working
well but possibly a 2 degree negative gradient at 50 feet in 280 feet of water.

Badly equipped planes were scarce and not bothersome.

One firm contact was made of a periscope on a moonlight night
(31 March). Believed his mission was A/S. Position 14-45N, 109-19E, about 12
miles off Indo-China Coast.

K. MAJOR DEFECTS
A. ENGINEERING COMPLAINTS.
1. Reduction Gears.
After being depth charged on 23 March the ship's noises were monitored
by the NLI and the port and starboard reduction gears were found to be excessiv-
ly noisy.
The reduction gears were opened and the bull gear and pinion gears
were given a visual inspection while being jacked over by the jacking gear
and no signs of wear or other defects could be noticed.
The reduction gears were then sounded by stethoscope and both gears
were found to be a knock in them. The knock was clocked and found to occur
with every revolution of the shaft. The knock sounded loudest at the outboard
pinions, but the source or the cause could not be definitely established.
The reduction gear oil strainers were cleaned and no foreign matter
could be found that would indicate that the gear teeth were not satisfactory.
A one hour full power run was conducted and no temperature rise was
found to be excessive on either the port or starboard gear. However the knock
in both sets of reduction gears persists and while it shows no signs of in-
developing into more serious trouble it is believed that something is
radically wrong and should be corrected this refit to silence
the ship.

K. MAJOR DEFECTS (continued)

... Machinery Derangements (Electrical)

March 20th. - Renewed the connecting rod bearings on #5, 7, 8, 14 in
16 units and #8 main bearing on #2 main engine. These bearings were found
to be badly pitted. The first was pulled because of high heat, and the others
were found while looking at the rest of them.

April 13th. - The overload relay contact for the forward main battery
contactor holding coil burned out. Repairs were made with replacement spare
parts.

April 14th. - The reverse current relay for #2 main generator was
burned out when it failed to function properly on reverse current from the main
battery. Repairs were made with replacement by spare parts.

April 14th. - Zero ground on the D.C. supply to the Radar IFF gear
occurred while charging batteries on the finishing rate and the charge had to
be secured until the ground was cleared.

April 15th. - Battery water test prior to watering the main battery
showed the water to be milky colored and to contain fine particles of some
foreign matter. An investigation led to the discovery that the Ion exchangers
were not functioning properly. The Duolite (C-2) had broken down and was
being carried away by the flow of water through the exchangers. The Ion ex-
changers were by-passed and not used for the remainder of the patrol. The Ion
exchangers on this vessel are installed upside down.

During the forth coming refit it is expected that the exchangers will
be reinstalled right side up and new Duolite (C-3) will be used.

C. TORPEDOES.

A vacuum leak-meter test put on the twenty-two Mark 14-3 torpedoes,
uncovered three torpedoes with leaky exhaust valves and no tackiwax. Had this
test not been made at least three torpedoes would have leaked during the period
when the bow tubes were flooded for 1 1/2 hours. It is recommended that shop
routines include the leak-meter test.

The midship section nut for the vent lead was less than hand tight
on one torpedo and #66471 had a bad leak in the pre-heater connection at the
brazing. The leakage from this latter torpedo increased
from 100# per day to 1,000# per day by the end of the run. It was decided
not to attempt shipboard repair. We planned to give the torpedo a quick air
charge before firing. Neither of these torpedoes was expended.

K. MAJOR DEFECTS (continued)

Air Compressors: - Trouble was experienced in No. 1 air compressor due
to excessive head pressures in the third stage cylinder. Taking leads it was
discovered that the clearance was .051", where .063" is the recommended
clearance. Lack of proper clearance caused carbonation in the 3rd. st ge. These
particles were carried into the 4th stage around the valves, often preventing
proper seating. To remedy the situation both heads were removed and
cleaned out. A gasket of .011" was added under the 3rd stage head increasing
the head pressure of that stage by 40 lbs.

Conning Tower Hatch: - The conning tower hatch leaked during the initial
stages of the dive. It is believed that this was due to a low spot on the
hatch gasket which should be checked carefully on refit.

L. RADIO

Reception of VILC was generally good. A log of radio receiving
conditions is forwarded in accordance with CFF 71 despatch 020916 of March 1945. Inter-
ference was generally near VILC frequencies, especially 12630 and 9250 kcs. The latter, however, gave
the best reception and is the most used frequency. The 4370 frequency was
useless as the signal-to-interference ratio was usually about 1-5. Interference
was greatest on the 1200 Z schedule.

Reception of WN was fair. Interference was heavier than on the previous
patrol. Interference was of the same nature as that on the VILC schedule.
Following is a list of the date-time groups of messages received from ComNav
Group Chin addresses to subs 7th. Fleet and N. Ad: March: 221455, 230530,
241634, 260910, 280530, 291707, 290845, 290959, 300920; April: 010934, 011654,
021558, 031350, 091727, 101715, 130920, 141729, 151325, 171555.

The present schedule of Wolf Pack frequencies, with a new plan each month
is a great improvement over the old frequency plan. CFF was used for commun-
ication with other boats. No interference was encountered on these frequencies.

Four messages were transmitted to VILC on ship-shore frequencies with less
than usual interference. On 19 April four stations, including VILC, answered
the initial call-up on 8470 kcs; and the message was cleared to VILC with no
interference.

No instances of jamming were noted, and such interference as was present
could usually be easily detuned.

The only material casualty to radio equipment was the blower motor of the
TBL transmitter which on 15 April began smoking heavily. This was found to be
due to the inboard brush being worn almost to the holder, and an extremely
dirty commutator. The outboard brush was in good condition. This motor was
to have been overhauled during the previous refit, but it is believed that
only the outboard brush was worked on. On 20 April an L 203 line filter on AC
input to power pack for RL-8 burned out putting one RL out of commission.

-20-

— page 86 —
L. RADIO (continued)

The Loran gear had only limited use during this patrol due to the fact
that the Darwin stations were the only ones for which we had charts or
tables. Fixes were not obtained south of the Barrier and in the eastern
Sea which were, generally, within 30 miles of star fixes. The errors observed
were largely latitude errors due to the sharp angle of intersection of the
lines of position of two stations to the east of us. The new Uluong and
Ulithi stations were picked up in the South China Sea areas with good signal
strength. When these stations go into full operation, fixes should
be obtainable in the South China Sea areas.

M. RADAR

SJ-1. SJ performance was very good, the difficulty of two range stops
encountered on the first patrol, having been definitely eliminated during the
last refit. The performance of the range unit, a weak point in the SJ-1 radar
in the past, was improved tremendously. This is believed to be due to the
separation of six inches between the range unit and power training control
unit, also made due to the last refit. It is concluded that the intense heat
from the control unit had been affecting circuit constants in the range unit,
thereby making proper adjustment impossible.

Spasmodic interference was encountered after two weeks on patrol in the
form of high noise level. It is believed that the modulation network, which
was found to be leaking oil after 300 hours operation, was mainly responsible
for the above interference, as the interference has not recurred since re-
placing the network. All other failures were due to bad tubes and blown
fuses. Out of a total of 458 operating hours, all but 2 hours were spent
in continuous usage. This exceptional performance record is believed due
to the thoroughness of a weekly maintenance. While in the patrol area, a
keying procedure of one minute in five was used, using the "A" scope as a
10 cm search receiver for the remaining four minutes. Distinction between friendly
and Japanese 10 cm radar was unsuccessful.

Sensitivity: Furthest contact on land - 120,000 yards.
Submarines, from 8000 to 9000 yards.
SC's from 4000 to 6000 yards.
PG's from 9000 to 12,000 yards.
Small fishing boat, 5000 to 6000 yards.
Birds out to 5000 yards.
Hospital ship - 25,000 yards.

SD-5 again proved its standing as a most reliable submarine
radar unit. It was used throughout the run and gave excellent performance.
Split second keying was used and to the best of our knowledge, there was no
DFing by enemy detectors.

Planes were detected up to ranges of 32 miles, however
initial contacts were at 15 miles or less, thereby suggesting that patrols
are being conducted at low altitudes. LOMBOK Island was picked up at 78 miles,
lower land at 30 to 35 miles.

-21-

— page 87 —
M. R.D.R (continued)

The BN functioned throughout the patrol with no loss of operating
time.
The BK failed once and the spare unit was immediately put into
service within five minutes of the reported failure. Examination of the
inoperative unit disclosed two type 7193 tubes to be defective. They were
replaced and unit returned to normal operation.

XCV. An extensive overhaul of the low and intermediate band antennas
was accomplished during refit and a standard APR search antenna was to
be used in case of failure of any of the tuned antennas. A change of design
in the mounting of the low-band antennas resulted in a water-tight antenna
circuit, even though two stubs were broken off during depth charging. The
intermediate band antennas however, grounded out as in the first patrol,
indicating that a different method of mounting should be employed.

The high frequency receiver proved to be a "dud" as we were unable
to pick up anything but our own SJ, even though we had 10 cm interference on
the J "K" scope in our own transmitter was secured. The furthest our SJ
band was an SD signal at an estimated range of 38 miles. During the entire
patrol there was a notable absence of radar signals. How-
ever, none was not heard at 3 miles. Performance obviously was
erratic and unreliable.

Radar Countermeasures. With the exception of one possible case of
DFing of our SJ, no enemy counter-measures were encountered. During the
approach on the convoy 28 March, the PPI of the SJ plainly showed two
escorts breaking away at a range of 4000 yards and heading straight towards
us, suggesting that we had been detected by radar with fairly good
accuracy. (10 cm. radar interference had been noted on the bearing of the
convoy). After closing to 5000 yards we were fired upon by what appeared
to be 3" shells, forcing us to dive, further suggesting good range accuracy.

N. SONAR.

Sound listening conditions on the whole were good, but as luck would
have it, poor during our approach on 23 March. Pinging was not picked
up until we were in to 3500 yards and screws were picked up shortly thereafter,
however after once getting tuned to the proper frequencies, we were
able to pick up pinging at 8-10,000 yards during evasive maneuvers at
150 feet.

All casualties were caused by depth charging, the most serious of which
was the flooding out of the QB head. Many leaks occurred about the base of
the guide frame and on top of the JK so chest also. Both train
motors were flooded out as a result of this leakage but one motor was washed
off with fresh water and baked dry and returned to service on the JK-QC. The
other motor was mounted on the QB side and worked for a few hours until
the head itself failed, for which nothing could be done.

0. DENSITY LAYERS.

B/T acted irregularly after depth charging, giving a looped
card on change of depth. Temperature always checked closely with engine-
room thermometers, however.

It is safe to say, that the waters five to ten miles off the INDO-
CHIN. coast were stagnant and stratified. There was always a sharp negative
gradient at periscope depth, due no doubt to the absolute calms that pre-
vailed days on end.

P. HEALTH, FOOD, AND HABITABILITY.

A gunner's mate striker not only succeeded in running a .30 caliber
ramrod through a machine gun silencer, but continued to pierce the palm
of his left hand between the third and fourth fingers. He was given treatment
and sterile dressing as applied by our competent "Doc" let the hand heal
with no ill effects.

All hands were administered the cholera vaccine a week prior to
entry into port. No pathological complications were experienced although
sore arms and headaches were a prompt yet short reaction.

The food with its superb and unique preparation is a noted feature.
Even the extra supply of lamb which we carried aboard was made very palatable.
Our cooks and baker made meals a pleasure. Ice cream was a frequent dessert.

The health of the crew is excellent and no transfers are anticipated
due to medical reasons.

Q. PERSONNEL

Performance of personnel was one hundred percent excellent.

V. REMARKS.
There was no opportunity to conduct any coordinated attacks. For patrol purposes, the area was divided between the boats available.

It is certain that no shipping passed close to shore after the contact on our first day in the area. The landing on OKINAWA may have influenced traffic to hole up, but it is not clear why they should wait until OKINAWA is a U.S. Operating Base.

FIRST ENDORSEMENT to:
USS BOARFISH Report
of Second War Patrol.

From: Commander Submarine Squadron TWENTY-SIX.
To : Commander-in-Chief, United States Fleet.
Via : (1) Commander Submarines, SEVENTH Fleet.
(2) Commander SEVENTH Fleet.

Subject: USS BOARFISH (SS327) - Report of Second War Patrol.

1. The second war patrol of USS BOARFISH was conducted
enroute to and in the SOUTH CHINA SEA off the East Coast of FRENCH
INDO CHINA. Thirty-five days were spent north of the MALAY BAR-
RIER, the last two of which were enroute to SUBIC; twenty-nine
days were spent submerged. Submerged patrols off the INDO CHINA
coast were conducted generally five to ten miles off the coast
while night surface patrols were usually conducted at distances
of ten miles or greater.

2. Two special (hazardous) reconnaissance missions
were completed during one of which damage was inflicted on the
enemy. These missions are covered by separate report.

3. The patrol was characterized by few enemy contacts.
Three properly marked hospital ships were sighted; prompt
appearance of an enemy plane after one of these sightings indi-
cates that the hospital ship possibly reported BOARFISH's presence.
A single AM patroling off SURABAYA was avoided. One definite
unidentified periscope was sighted. Two convoys were contacted,
attacks on both of which were frustrated by alert escorts.

CONTACT NO. 1: While proceeding north, on the surface, in the
vicinity of GREAT NATUNA ISLAND, one estimated 1500 ton AK with
four converted yacht type escorts was sighted. A submerged appro-
ach was commenced 15,000 yards ahead of the convoy but BOARFISH
was detected by escorts, broke off the approach and took evasive
action. Fifteen depth charges were dropped during the subsequent
attack which inflicted considerable minor damage and permanently
disabled the QB sound head and XCV on low and medium bands.

TORPEDO ATTACK NO. 1: While patrolling on the surface off QUIN
HON, FRENCH INDO CHINA, radar contact was made with a northbound
convoy of four or five pips, the nearest of which was 4800 yards.
Echo ranging had been heard about twenty minutes previously in
that direction. At a range of about 4500 yards BOARFISH was de-
tected by an escort, later identified as a PG of the HASHIDATE
class, who commenced pursuit and opened fire with one gun. At a
range of 4000 yards three steam torpedoes were fired from the
stern tubes with the angle on the bow estimated as 30° [HANDWRITTEN: 01212] The

escort did not realize he had been fired at and, with the splashes
getting close, BOARFISH dived and evaded at periscope depth. A
second PG or DE joined the hunt and although they approached at
one time to 900 yards echo ranging and listening at slow speeds
BOARFISH was not detected. The position of the escort on being
sighted through the periscope indicated that either the angle on
the bow had been much sharper or courses had been changed. BOAR-
FISH surfaced an hour later, stood north and again contacted the
escort visually and by radar. The escort effectively prevented
her gaining position ahead of the convoy.

4. On return from patrol the health and morale of
the officers and crew was excellent; state of cleanliness of the ship
was excellent. Sound test did not indicate an unacceptable noise
level in the reduction gears and it is believed that the noise
level will be further reduced by realignment of the attached lub
oil pumps. The QB sound head will be replaced and a normal
refit given by ASWESRON and Submarine Division 261 relief crew.

5. The squadron commander welcomes the officers and
crew to this area and regrets their lack of opportunity to in-
flict damage on the enemy.

(A) Prologue.
Moored alongside U.S.S. ANTHEDON in SUBIC BAY, PHILIPPINE Islands under-
going routine refit by Relief Crew #2 of Submarine Division 261, with CSD 261
as Administrative Division Commander. On 6 May 1945 refit was completed and
officers and crew returned aboard from rest camp. Commander R. L. Gross, USN,
was relieved as Commanding Officer by Lieutenant Commander E. C. Blonts, USN.
Lieutenant A.F. Rawson, USN was detached for duty with Submarine Division
261 and Lieutenant J.B. Copeland, USNR reported aboard as Executive Officer.
A total of 18 enlisted personnel were transferred to Submarine Division 261 and
20 were received.

No alterations were accomplished. Ship was not dry docked. Not wiped or
depermed. Sound test on 7 May 1945 was found satisfactory in all respects.

Completed 5 days training and 3 day loading period on 15 May 1945. During
the training period many helpful suggestions were given the new Commanding
Officer both by Captain J. H. Willingham, Jr., USN, Commander Submarine Div-
ision 262, and Commander R. L. Gross, USN, Commander Submarine Division 261.

        until,

2200 I When having reached release point parted company with escort.

        During the period 16-20 May made daily trim and training dives and
        conducted fire control drills.

17 May
1445 I Aircraft Contact #1, Lat 14-09 N, Long 116-05 E made sight contact
        on large bomber at range of 18 miles. Showed IFF and did not close.
        Least range 18 miles.

        tions. Lat 9-13 N, Long 110-20 E. Could possibly have been
        BLACKFIN.

1357 I Aircraft Contact #3, Lat 4-45 N, Long 109-03 E. Made sight contact
        on plane coming out of the overcast with a zero angle on the bow
        at estimated range of 5 miles. Not identified as one of ours, so
        submerged.

1458 I Surfaced.

20 May
2107 I Made radar contact on GREAT NATUNA ISLAND. Had planned to be well
        into the Soebi Kechil Strait between GREAT NATUNA and SOEBI KECHIL, but from
        the time we left Subic Bay until off GREAT NATUNA, we had been
        bucking moderate head seas so that running on three engines had
        averaged only 12 knots.

0638 I In the morning twilight and 20 miles east of GREAT NATUNA, a string
        of bright lights on the island were turned on, probably landing
        lights for the airstrip. With the possibility of a plane coming
        out to look us over, submerged for a day's patrol just to the east
        of the Strait between GREAT NATUNA and SOEBI KECHIL.

2052 I Surfaced. No contacts.

U.S.S. BOARFISH (SS327) - Report of Third War Patrol.

2215 I Began picking up small contacts on the SJ radar. Since nothing
        could be seen in the bright moonlight, it is believed these were
        secondary echoes from the surrounding islands. There was no
        indication of the reported radar station at SOEBI KETJIL on the
        KCV radar detector.

21 May
0104 I Received Serial Peter changing our patrol area to Easy 8, to work
        under the BLUEBACK.

0654 I Submerged for day's patrol east of TAMBELAN ISLANDS on traffic
        route between SINGAPORE and west coast of BORNEO.

2048 I Surfaced. Nothing sighted during the day. Began running full
        speed on three engines and then four engines, after completion of
        battery charge, in order to utilize the few hours of darkness to
        get as far as possible into KARIMATA STRAIT before dawn.

2314 I Crossed Equator in Longitude 108-10 E.

22 May
0324 I Received Serial William reassigning us to area Easy 9 to work with
        BLENNY and CHUB.

0620 I Began transit of KARIMATA STRAIT.

0652 I Submerged.

2047 I Surfaced with SJ radar out of commission, a fine time for this to
        happen.

2307 I SJ radar back in commission. Picked up SJ interference bearing
        273° T. Established communication with BLENNY, who told us he
        would be in area E-9 on the 25th and also that the CHUB had been
        calling us asking for our position. Not desiring to transmit in
        KARIMATA STRAIT, did not answer.

23 May
0245 I Completed transit of KARIMATA STRAIT.

0552 I Sent message to CHUB giving our position.

0640 I Entered assigned patrol area.

0726 I Submerged for day's patrol on possible traffic route from CAPE
        SELATAN to KARIMATA STRAIT.

2034 I Surfaced and headed for possible traffic route between CAPE
        MALAYOER and BAWEAN.

24 May
0045 I Received message from CHUB giving his position and requesting ours.

U.S.S. SCARFISH (SS327) - Report of Third War Patrol.

0123 I Sent message to CHUB giving position, course and speed and requesting
        instructions.

0149 I Received message from CHUB assigning coordinates for the area and
        ordering rendezvous for tonight.

0659 I Submerged for day's patrol.

1254 I Ship contact #1, Lat 4-38 S, Long 112-11 E. Sound picked up distant
        pinging bearing 050° T. Changed course to head for it.

1310 I Sighted masts and smoke on the horizon. Went to battle stations.

1334 I Now had two sets of masts in sight, which at

1342 I Could be determined as one merchantman and one escort.

1346 I Three ships and the escort present. In the haze it really looked
        as if we had something. With convoy showing zero angle on the bow
        decided to wait for them to come to me. Convoy tracked at 5 knots,
        zig zagging 15° each side of base course 200° T.

1420 I At estimated range of 4200 yards, target still showing a zero angle
        on the bow, began to pull off track to port for stern tube shot. At
        this time, from bows on, first ship looked like a fair sized ship.
        The other two ships were obscured by the first. The escort had
        conveniently pulled over to the starboard bow of the convoy.

1432 I Convoy zigged to his right and I got my first good look at the target.
        Extreme disappointment for my convoy became three small river or
        ferry boats with a PC-13 type escort. When the angle on the bow
        had been zero, I should have had some idea that the ships were small
        because of the way they were rolling in the 5 foot swells.

1448 I The first river boat passed the firing bearing with an angle on the
        bow of 80° port and range of 1400 yards. These boats were, judged
        in comparison with the escort 140 feet long of possible draft 3 feet.
        Estimated displacement 80 tons. All three were identical in appear-
        ance. They had about three feet freeboard, a fairly high bow, open
        bridge mounted on the upper deck. From the bow aft, the main deck
        was open from side to side. The upper deck was the same size and
        open as well. The boiler was in plain sight on the main deck (A
        sketch of this boat is attached to this patrol report) No cargo or
        troops could be seen.

1452 I The range to the escort was now 4000 yards, out of torpedo reach.
        I don't believe the torpedoes would have run shallow enough in these
        swells to hit him. Broke off attack.

1459 I The escort had now gone back to the port quarter of the convoy and
        pinged directly on us eight times. Evidently the captain did not
        believe his sound operator for he went back to his ugly ducklings.

2022 I Surfaced and headed for CHUB's estimated position for rendezvous.
        Sent contact report of convoy to CHUB and BLUEBACK on wolfpack
        frequency.

2205 I Picked up SJ interference, identified as CHUB, and at

2245 I Rendezvoused with CHUB, who passed over instructions for patrolling
        the area by line throwing gun. Tested VHF communications which
        were effective to the amazing range of 1 mile.

25 May
0048 I Parted company with CHUB, headed for patrol station for the day.
        CHUB patrolling 25 miles to the northwest.

0653 I Submerged for day's patrol on traffic route between CAPE MALATOJOER,
        BAWEAN and SOERABAJA.

2018 I Surfaced.

26 May
0042 I After having picked up SJ interference at 0017 I, exchanged calls
        with CREAKER.

0651 I Submerged for day's patrol on same traffic route as yesterday.

0805 I OOD sighted tops of a ship bearing 135° T. Went to battle stations
        and began approach.

0812 I Identified target as British submarine and broke off approach.

2017 I Surfaced. Having had no ship or plane contacts with exception of
        Allied submarine, decided to patrol on the surface tomorrow.

27 May
0045 I Picked up SJ interference. Headed toward.

0110 I Exchanged calls with BLENNY and at

0115 I Established VHF communication with BLENNY. Passed over information
        on the area, our contact of the 25th, location of CHUB, and plans
        for the next day. But at

0130 I Received Serial George ordering us to leave area Easy Nine and pat-
        rol in area Easy Two west and northwest of the THOUSAND ISLAND Group.
        Parted company with the BLENNY and set course for new area.

0649 I Ship Contact #2, Lat 5-04 S, Long 117-35 E, made SJ contact at
        range 6000 yards on small ship or sailing vessel. He was down moon
        and couldn't see him.

0656 I Submerged for trim dive, to routine torpedoes and keep an eye on
        this contact.

U.S.S. "BOARFISH" (SS327) - Report of Third War Patrol.

0839 I Surfaced with contact, now identified as two masted junk type sailing
        vessel of about 30 tons. Manned 20 mm and 40 mm guns and closed to
        investigate. Upon closing saw that ship was flying the Japanese
        flag. Circled at safe distance looking for Japs or evidence of
        concealed guns and taking pictures.

0920 I Put boarding party aboard ship now identified as UNKO MARU Number
        177. Found no Japanese or arms. Cargo consisted of rattan and
        tanning resin. Removed Japanese flag and ships papers. Since the
        ship was a sailing vessel manned by natives from Borneo and cargo
        was not contraband of war, allowed it to proceed.

0952 I Pulled clear of ship and proceeded toward assigned area.

1222 I Aircraft contact #4, Lat 5-05 S, Long 110-02 E. Sighted BETTY
        type bomber bearing 220° T at range 3 miles. With plane closing
        fast, submerged.

1410 I Surfaced.

1509 I Aircraft contact #5, Lat 5-07 S, Long 109-48 E. Sighted ZERO
        bearing 340° T, range 8-10 miles on easterly course apparently
        searching.

1512 I Plane turned toward and headed in. Submerged. It appears that
        they have us pretty well vectored in. These plane contacts had so
        slowed us down that the area could not be reached at dawn as I had
        planned and to run on the surface now would cause us to pass
        through the THOUSAND ISLANDS during daylight. Decided to remain
        submerged during daylight and to pass through THOUSAND ISLANDS
        submerged tomorrow.

2030 I Surfaced.

28 May
0714 I Submerged for day's patrol north of THOUSAND ISLAND Group.

1506 I Sighted small sea truck towing 3 small junks passing between the
        islands to the south.

2108 I Surfaced and began east west patrol in area between SUMATRA and
        THOUSAND ISLANDS.

2307 I Made radar and sight contact on small patrol craft on course 190°
        T, speed 6 knots. Evaded.

29 May
0030 I Made sight contact on second patrol vessel bearing 180° T, range
        8000 yards on an easterly course, speed 10 knots. Opened to the
        north.

- 6 -

— page 102 —
U.S.S. BOARFISH (SS327) - Report of Third War Patrol.

0221 I Made radar and sight contact on third patrol boat, similar to SC
          type who persistently tried to close. He challenged us four times
          sending 1 and 2 letter signals each time, as follows "LD", "W", "T"
          and "C". Cleared area to westward.

0422 I Made sight contact on fourth patrol boat bearing 010° T, range
          7500 yards. Evaded.

          I believe these four contacts were all different ships and that
          the Japs keep this area well patrolled.

0716 I Submerged for day's patrol off SAINT NICHOLAS POINT.

1257 I Aircraft Contact #6. Sighted fighter type plane through periscope
          at range of about 2 miles. He flew off to the south and was not
          seen again.

1405 I Sighted three ships and 2 escorts coming across from the SUMATRA
          shore headed for BATAVIA. This convoy consisted of one large stack
          aft ship, evidently a tanker, followed by a SUGAR BAKER and a small,
          appearing FOX TARE DOG of about 1000 tons. The escorts
          were converted trawlers and were not echo ranging.

1413 I Went to battle stations and commenced approach on the SUGAR ABLE.
          Decided to fire four torpedoes forward at the leading ship, then
          two at the SUGAR BAKER if opportunity permitted. Set all torpedoes
          on 4 feet.

1440 I I was now dead ahead of the port escort at a range of 1500 yards
          and he had a 5° starboard angle on the bow so decided to shoot.

1442 I With a torpedo run of 2350 yards, track angle of 77° port and
          average gyro of 10° starboard commenced firing four torpedoes
          forward. Temporarily lost depth control.

1443-43I One torpedo explosion in the direction of the target. This would
          correspond to number three torpedo with a run of 2225 yards. I
          believe this ship was damaged.

1444-30I Back at periscope depth and screws of escort sounding very loud,
          took a look at the escort. He had a zero angle on the bow, coming
          in fast and close aboard, did not look at the target but went deep
          immediately. The chart showed 240 feet at this spot so went to
          215 feet.

1445 I As we were passing 100 feet, first depth charge followed by two
          more fairly close below and astern. These depth charges must have
          jarred the azimuth ring on the JP loose for there was now a wide
          divergence between JP and QB bearings on the escort. That the
          azimuth ring was loose was soon determined and an attempt was being
          made to align it with the QB head, using the JK head for searching
          for the other escort.

DENTIAL
1449 I The escort went over us but did not drop. (See separate Top Secret
        report).

1452 I Still trying to line up the JP head went aground in 216 feet of
        water, wiping off both sound heads and making much noise.

1456 I String of 8 depth charges, close astern and above.

1459 I Backed off the submerged hill, evidently hitting port propellor on
        the bottom at this time for there was a heavy bump astern. Eased
        up to 180 feet and tried to fish tail away from escort. JP head
        was still not lined up properly but clamped the azimuth ring where
        he was. Every time the escort headed away went to 70 rpm and he
        was right back in again. With the escort hanging on like a leech,
        decided to head away from the coast and, if he was still there at
        dark, try to out run him on the surface.

1600 I Changed course to 030° T, true bearing of the escort slowly drawing
        aft.

1719 I Escort dropped three more depth charges farther away. Evidently he
        had a false contact.

1754 I On the way up for a look, two more depth charges quite a ways off.
        Decided to stay down a while longer.

1850 I At periscope depth.

1908 I Lost sight of escort headed for BATAVIA.

2048 I Surfaced and proceeded on courses to get northeast of THOUSAND
        ISLANDS to send message telling of damage to target and BOARFISH.
        I did this to prevent DF'ing in specified patrol area and to give
        idea that submarine was clearing area. Found that any speed over
        14.5 knots caused excessive vibration in port shaft. Lined up JP
        as best we could from topside.

30 May
0025 I After picking up SJ radar interference, exchanged calls with BLUEBACK,
        headed into area. Came close aboard and passed over information on
        convoy, patrol boats and own material damage.

0123 I Parted company with BLUEBACK.

0435 I Cleared BOARFISH First to CTF 71 and at

0440 I Changed course to head back into assigned area.

0712 I Aircraft Contact #7. SD radar made contact on plane, not in sight
        from bridge, closing. Being in 13 fathoms of water, submerged.

- 8 -

— page 104 —
U.S.S. BOARFISH (SS327) - Report of Third War Patrol.

Being northeast of the THOUSAND ISLANDS decided to patrol that
area for the day and see if anything went down the eastern side.

2052 I Surfaced, having made no contacts during the day.

2230 I Headed back in to patrol area.

2236 I Received Serial Roger instructing BOARFISH to go to FREMANTLE for
        repairs.

31 May
0706 I Submerged.

2034 I Surfaced, being clear of SINGAPORE-SURABAJA bomber range by morning
        decided to run tomorrow on surface.

1 June
1355 I Aircraft Contact #8, Lat 5-21 S, Long 113-16 E, sighted fighter
        type plane bearing 060° T, range 7 miles.

1357 I Plane changed course to show us a zero angle on the bow and started
        in. Submerged. Decided that he would go home about 1830, so would
        surface at 1900 and move on.

1856 I Surfaced.

1859 I Aircraft Contact #9. Sighted fighter type plane bearing 116° T,
        range approximately 6 miles, headed for us again. Submerged. He
        out waited us that time.

2045 I Surfaced. We had now lost so much time that a transit of LOMBOK
        on the second of June was impossible. The best we could manage
        was to run submerged tomorrow and be at the entrance to the Strait
        at twilight the morning of the third.

2 June
0005 I Picked up SJ radar interference on same true bearing as GREAT
        MASALEMBO ISLAND. However as we passed the island, the bearing
        moved off. This may have been one of our submarines but at no
        time did he steady on us or attempt to challenge.

0530 I Lost contact on radar interference.

0644 I Submerged.

2038 I Surfaced and headed for LOMBOK at our maximum speed of 14.5 knots.

3 June
0118 I Picked up SJ interference bearing 180° T and tracked it until 0320
        I. This must have been one of our boats just through LOMBOK headed
        up through the KANGEAN's.

- 9 -

— page 105 —
U.S.S. BOARFISH (SS327) - Report of Third War Patrol.

0448 I XCV had indication of Jap air search radar at 165 mcs, believed
        to be located on BALI as listed in effective publications. This
        interference continued until we submerged.

0550 I Picked up weak radar interference on the XCV at 520 mcs, estimated
        to be airborne.

0553 I Aircraft Contact #10. Twenty miles north of LOMBOK STRAIT, SJ
        radar had a contact bearing 234 T at 6,000 yards. This rapidly
        changed to 259 T and closed to 4,000 yards, submerged.

0950 I Began transit of LOMBOK STRAIT.

1446 I JP picked up screws bearing 109 T.

1453 I A small, brown colored vessel was seen through the periscope bearing
        109 T at an estimated range of 10,000 yards. This was the least
        range and the vessel was soon out of sight, probably headed into
        AMPENAN. I can't be certain that this was a patrol boat.

1800 I Completed transit of LOMBOK STRAIT, having experienced an average
        set of 2.0 knots.

2042 I Surfaced twenty miles south of LOMBOK and set course in the joint
        zone for FREMANTLE.

3-6 June Enroute FREMANTLE.

7 June
0810 I Made deep dive for tightness.

1330 I One of the air flasks in a Mark Eighteen torpedo in the after
        torpedo room carried away, damaging the afterbody but causing no
        damage to ship or personnel. This casualty is discussed under
        section V.

8 June
0130 I Sighted ROTTNEST ISLAND Light.

0930 I Arrived FREMANTLE.

(C) Weather.

     From Subic to the area and in the Java Sea the weather was typical May
weather - frequent clouds drifting by with water pouring out of them. No
storms. Indian Ocean clear with a wind from the southeast of 10 to 15 knots.

(D) Tide and Current.

     A northerly set in the South China Sea and a westerly set in the Java
Sea, about .5 knots. In the northern approaches to Sunda Strait, the set
was to the south - into the strait, at .5 to 2 knots. The strong current
was experienced at night under a full moon. Current in Lombok was to the
south averaging two knots while running submerged and going from sixty-five
to one hundred feet every half hour.

(E) Navigational Aids.

     No navigational lights or buoys were sighted. Loran was carried but
was of no use since we were out of range of known stations the entire patrol
except for the first day out of Subic and while in the Indian Ocean. Some
stations, probably in China, appeared while passing through the South China
Sea, but we carried no charts or tables for them.

(H) Attack Data.

U.S.S. BOARFISH Torpedo Attack No. 1 Patrol No. 3

Time: 1442 (I) Date: 29 May 1945. Lat. 5-48S Long. 105-58E

DESCRIPTION: - Three ships and two escorts with plane cover were sighted
  through periscope during daytime submerged patrol. Ships were
  in column with one escort patrolling each side. Leading ship
  was large SUGAR ABLE, length 450-500 feet by periscope formula,
  tonnage unknown. This ship was similar in appearance to a Whaler
  but had only 1 stack (sketch attached). The second ship was
  a SUGAR BAKER and the third was a FOX TARE DOG of about 1000 tons
  of ancient vintage. Escorts were converted trawlers. Visibility
  20 miles. Sea force 3 from east.

SHIP'S DAMAGED: - SUGAR ABLE.

D.M.GE DETER- One timed hit 1 minute 43 seconds after first torpedo fired.
MINED BY:

TARGET DRAFT: - Unknown COURSE - 100 SPEED - 8 knots. RANGE - 2600 yds.

OWN SHIP DATA

Speed - 3 knots. Course - 191 Depth - 65 feet Angle - 1/2°down.

FIRE CONTROL AND TORPEDO DATA

Type Attack: - Day submerged periscope attack.

  Convoy was zigging between 080 T and 120 T. Firing position was
  reached 1500 yards ahead of port beam escort. With convoy on
  course 100 T and due to zig away in 3 minutes, fired 4 torpedoes
  set at 4 feet and on an 78 port track, spreading 150% of target
  length along target track. One hit heard (but not observed due to
  loss of depth control) 103 seconds after first torpedo was fired.
  Action by escort prevented observation of results or attack on
  other two ships.

(I) Mines.

No mines were seen. No evidence of mine laying or mine sweeping was
observed.

(J) Anti-Submarine and Evasion Tactics.

The convoy encountered on the 25th of May, had a PC-13 type escort equipped
with echo ranging and listening equipment. He used a combination of listening
and echo ranging at variable intervals. When echo ranging and he had us within
30 degrees of his bow, he hit us frequently. However, he never seemed quite
certain we were there. His escort plan was to slowly circle the convoy, ping-
ing and listening. Pulled clear at periscope depth.

The convoy encountered on the 29th had air cover as well as two converted
trawler type escorts. There was no evidence that either escort had echo-rang-
ing equipment. During the early stages of his counter attack, while we were
attempting to fish-tail away, he stayed with us too efficiently. However, when
we began to pull clear to the northeast on a steady course at slow speed, he
lost us. I believe that he was searching in the vicinity of the mud stirred up
by our bottoming and eventually made a false contact which threw him off the
scent as evidenced by the distance of his last five depth charges. Evasion
depth was the deepest available (too deep at one time) which meant from 150
to 180 feet in this area.

(K) Major Defects and Damage.

As has been the case during the two previous patrols of this vessel, the
upper conning tower hatch began leaking two days after departure on patrol.
From the time this hatch goes under water until 42 feet keel depth, the hatch
leaks although it is closed as tightly as possible. Efforts have been made on
this patrol and previous patrols to stop this leak by shimming the various dogs
of the hatch and around the periphery of the hatch. This method, as was the
replacement of the gasket by the tender, is effective for a few days and then
the leakage begins again.

On 29 May, while evading depth charges, the ship struck bottom, while the
sound heads were rigged out. Both sound heads were rubbed off. Shortly there-
after the port propeller hit a rock or ledge on the bottom and bent one or more
blades of the propeller.

Running submerged at speed of 70 rpm gave a noise level three times above
that previously recorded and well over the acceptable sound level of best Naval
practice. This was determined by monitoring the noise level of the propeller
on the MIM.

The bent propeller caused excessive vibration at a speed of 14.5 knots or
over necessitating a speed of less. Below 14.5 knots vibration was noticeable
but not excessive.

U.S.S. BOARFISH (SS327) - Report of Third War Patrol.

(L) Radio.

     The NPT 1 schedule was copied, for the first time, during the entire patrol.
Reception was generally good, and no trouble was experienced in copying the
schedule, with the exception of two occassions when severe atmospheric inter-
ference caused some difficulty. No serials were missed.

     The shift to NPT 1 was an improvement over the VLØ reception during the
previous patrol, fewer periods of fading being noted and a generally stronger
signal. 9250 and 12630 kcs. were used exclusively. The usual CW and broad-
cast stations near all frequencies were present.

     Interference encountered on the Wolf Pack circuits was negligible and
communications with other boats was generally excellent and reliable. The only
use of VHF was with other boats close aboard, this marking the first occassion
we have raised anyone on VHF outside of an exercise area. Performance was
satisfactory up to 1 mile range.

     Two transmissions were made on the ship-shore frequencies without undue
difficulty. Both were relayed by VLXO to NPT 1, VLXO giving its usual excell-
ent service to boat traffic. The first transmission, on 4235 kcs, was accomp-
anied by the expected interference of CW signals and what sounded like a
squealer very near the frequency. The second transmission, on 12,705 kcs, was
notable in that no interference of any kind was encountered.

     There were no materiel casualties.

(M) RADAR.

     SJ-1: SJ performance was very good. Casualties were minor and total
loss to time due to casualties amounted to two hours and fifteen minutes for
this patrol.

     SJ operation was varied with the visibility and area. The SJ
was manned at night, a keying procedure being used, transmitting one minute
out of every five, and using the "A" scope as a 10 cm search receiver for the
remainder of the period. The twenty thousand yard PPI sweep continues to be
our basic sweep. It gives good coverage and large presentation of targets.

     The high voltage keying proved very useful. We were able to
exchange challenges and messages at ranges up to thirty miles with the CHUB,
BLENNY, BLU BACK, and CROAKER.

     Contacts: Longest range contact - Island of Lombok - 220,000 yards.
                Submarines - 11,000 to 16,000 yards.
                DE's (US) - 14,000 to 20,000 yards.
                SC's and PC's - 8000 to 14,000 yards.
                Sailing Vessels - 6000 to 8000 yards.
                Planes - 6000 yards.

U.S.S. BOAFISH (SS327) - Report of Third War Patrol.

(M) Radar (continued)

Casualties

were confined to tube failures which seemed to be
exceptionally high this patrol. This is believed due to lack of proper tube
tests during last refit, or possibly an influx of inferior tubes.

SD-5: - The performance of the SD-5 was generally good, but not as reliable
as the first two runs. The set was operated almost continuously in the area,
night and day, while on the surface. The split-second manually keying feature
incorporated in the SD-5 was used to prevent homing on the signal. The trans-
mitter was keyed for a period never longer than ½ second., the keying interval
varied from ½ to 2 minutes. We had no indication of any plane homing on the SD
using this system.

XCV: - In spite of losing the two grounded stubs of the low band antennas during
a quick dive, two days out of Subic, the XCV functioned normally throughout the
patrol. There was a noticeable absence of radar signals from aircraft sighted
from the bridge or detected on the SD. Only in one instance, while approaching
Lombok, did a search of known aircraft frequencies result in interception of a
signal. (520 mcs, 475 PRF). Landbased radar signals were detected at ranges
of 75 miles. It is believed that the use of a coaxial lead from the high band
antenna (1000 to 3000 mcs) limits the proper functioning of the 5AX unit, be-
cause of the attenuation of the incoming signals. The shielding of all antenna
cables with Belden Braid during the last refit proved very successful in
eliminating ship's machinery interference experienced in the past patrols.

(N) Sound.

Sound conditions in the Java Sea were better than average. All gear per-
formed normally, QB picking up pinging at an estimated range of 25,000 yards
for the first contact of the patrol. QB and JP picked up screws on the same
contact at 12,000 and 15,000 yards respectively.

On another occasion, JP picked up screws and was able to get a turn count
at 10,000 yards.

Casualties resulting from our first attack unfortunately were heavy. Both
QB and JK heads were wiped off and depth charging caused the JP azimuth plate
to jump out of alignment, resulting in poor bearing accuracy.

Because of simplicity of operation of the QB equipped with slip rings, all
lookouts were quickly and easily trained to stand sound watches. The frequency -
search plan as recommended in the Sound Operator's Handbook was used continuou-
sly and proved its value by resulting in the first contact.

(P) HEALTH, FOOD, AND HABITABILITY.

Health of the crew was excellent. One veneral case was reported by the
man concerned and treated on board.

Habitability was good. The installation of the authorized booster blower
in the ventilation supply would be a big help and is desired as soon as
possible.

During the second week on patrol, the mixing motor on the ice cream
machine burned out. We had no replacement nor the means to rewind the
armature. As a result, we lost a pleasing variant of the routine menu. It
is recommended that aspare motor for the machine be supplied to all submarines.

After eight months in commission this ship was finally able to procure
its allowance of ten movies. Needless to say, they were good morale boosters.

We were more unfortunate in the matter of Armed Forces Radio transcription.
No exchange library was available in Subic, so we listened to the same records
for another patrol.

Through wearing out and loss the ship's library has shrunken to a pitiful
condition. None of the monthly shipments of books have reached this ship
since commissioning and there was no activity in or around SUBIC able or
willing to supply us with any books. The same condition exists in regard to
magazines. We departed on patrol with no new reading material whatsoever.

The food was adequate and well prepared. Departing from an advanced base
precluded procurement of any of the more fancy items which provide variety.
The only item we were unable to procure in sufficient quantity was eggs. We
had two cases when we departed. They didn't last long. All in all, we ate
good staple food, prepared in as many different waysas possible, and were
well satisfied.

(V) REMARKS.

(a) No mine sweeping activity encountered.

(b) The convoy encountered on 25 May indicates that traffic from
southern BORNEO to SURABAYA passes near BAWEAN ISLAND.

The convoy attack on 29 May was traveling close to the coast
SUMATRA and appeared headed close in for the coast of JAVA.

(c) The U.S.S. ANTHEDON gave us the best Mk. 14's I have seen. We
had no difficulties with them.

Six Mk. 18's were carried aft. The burner circuit on torpedo
#54599 grounded out, because a sharp edged metal clip holding
the hydrogen burner cable cut into this cable. The clip is
located on #3 after body strengthening ring. Similar clips
are used throughout the torpedo to string electric cables. It
is recommended that fibre clips be used to replace those now
used.

On June 7, the bottom blew out of the top air bottle in Mk.
18-1 torpedo, serial #56007, afterbody serial #2771. The
explosion damaged machinery in vicinity of air bottles and
deformed but did not rupture the afterbody shell. The torpedo
was charged to 3,000 psi May 25th, and gauged at 2950 psi on
June 2nd, but not charged. It was not moved in its rack or
worked on after June 2 prior to the explosion. It is believed
that the casualty was due to faulty material.

This vessel is completely equipped to carry Mk. 18's; and, if
possible, I would like a full load of electrics next run.

of Third War Patrol.

From: The Commander Submarine Squadron THIRTY.
To : The Commander-in-Chief, United States Fleet.
Via : (1) Commander Submarines, SEVENTH FLEET.
(2) Commander SEVENTH FLEET.

Subject: U.S.S. BOARFISH (SS327) - Report of Third War Patrol.

1. The third war patrol of the BOARFISH, the first for the
commanding officer as such, conducted in the Java Sea Area, was of twenty-
three days duration, twelve of which were spent in the assigned areas.
Patrol was terminated due to damage incurred from bottoming.

2. This patrol was characterized by several air contacts, a
convoy contacted which contained river boats too small for torpedo fire,
a junk which was boarded and a convoy consisting of one large tanker, one
medium and one small AK escorted by two converted trawlers. This last
contact was developed into a torpedo attack.

3. TORPEDO ATTACK NO. 1. 29 May 1945. This was a day peri-
scope attack on a three ship convoy with two escorts. Four Mk. 14 torpedoes
were fired on a 78° track, small gyros, torpedo run 2300 yards, depth set
four feet. One timed hit was heard but the nearness of the escort forced
early evasive action and damage to the target was not observed. While
evading the BOARFISH bottomed in 216 feet of water and wiped off the sound
heads. On getting off the bottom the port propeller was also damaged. The
BOARFISH was depth charged closely after this attack but no damage resulted
from the depth charging.

5. The BOARFISH returned from patrol clean and shipshape and in
good material condition, except for the damage due to bottoming. It is ex-
pected that the refit will be accomplished in the normal period.

6. The commanding officer, officers and crew are congratulated
upon the completion of their third patrol and for the damage inflicted upon
the enemy.

Subject: U.S.S. BOARFISH (SS327) - Report of Third War
Patrol - Comment on.

1. The Third War Patrol of the BOARFISH, under the
command of Lieutenant Commander E.C. BLONTS, U.S.N., was con-
ducted in the JAVA SEA. The patrol was of only twenty three days
duration, having been terminated early as a result of damage re-
ceived in bottoming on 29 May.

2. At 1405 on 29 May BOARFISH commenced an attack
on a convoy consisting of one large tanker and two considerably
smaller ships. At 1442 a favorable firing position was achieved
and four torpedoes were fired from the bow tubes at the tanker.
The intention to fire two additional torpedoes from this nest at
one of the minor ships of the convoy was frustrated by temporary
loss of depth control. One torpedo explosion from the direction
of the target corresponded to number three torpedo, but the tar-
get could not be observed because of the necessity of instituting
evasion tactics. Although the chart indicated forty fathoms in
this area, the BOARFISH grounded in 216 feet of water and sus-
tained sufficient damage to necessitate termination of patrol on
30 May.

3. The award of the Submarine Combat Insignia is
not authorized for this patrol.

4. The Force Commander congratulates the Commanding
Officer, Officers and Crew of the BOARFISH on their completion
of this first patrol in command for Lieutenant Commander BLONTS.
The following damage was inflicted on the enemy:

PATROL REPORT U.S.S. SCARFISH - 4TH PATROL

A. PROLOGUE
Moored alongside U.S.S. CLYTIE in Fremantle Harbor,
Western Australia, undergoing refit by Relief Crew #1 of Subm-
arine Division 301, with C.S.D. 301 as Administrative Division
Commander. On 23 June, 1945, refit was completed and officers
and crew returned aboard. Lieutenant (jg) O.B. NELSON, U.S.
Navy, was detached and Lieutenant L.A. FRANZ, U.S. Navy, and
Ensign R.H. WATSON, Jr., U.S. Navy, reported aboard for duty.
A total of 14 enlisted personnel were received and 19 were
transferred to Submarine Division 301.

The following alterations were completed:

(a) Strengthen outer hull in vicinity of #2 and #3 auxiliary
and safety tank; (b) Removed reducing valves and associated equ-
ipment to torpedo air impulse flasks; (c) Installed stop valves
in hydraulic lines to #5 FBT main vent operating cylinder to
allow use of #3 as a MBT prior to using fuel in #5 FBT; (d)
Installed ST periscope radar; and (e) Installed additional 40mm
gun on after cigarette deck. Ship was dry docked during refit
period for bottom preservation, renewal of sound head and re-
placement of propellers. Ship was depermed on 28 June. The
ship was given underway sound test on 2 July showing a high
noise level on both shafts. Ship was again dry docked on 3
July and port propeller replaced.

Completed seven day training period and 3 day loading
period on 4 July, 1945. Training was handicapped by the
stormy weather during all but two days of the period. However,
it was considered that the crew was sufficiently trained by 4
July. Captain Jesse L. HULL, U.S. Navy, Commander Submarine
Division 301, gave this vessel much help during the refit and
training period. Readiness for sea was set as 5 July, 1945.

5 July
1510 H Underway in company with USS BLENNY enroute to training
        area to conduct night exercises with assigned training
        vessels.
2228 H Completed training exercises, departed company of training
        vessels and set course in joint zone for patrol in accord-
        ance with Commander Task Group 71.1 Operation Order Number
        88-45. BOARFISH Task Unit Designation 71.1.4 with orders
        to patrol area E-8.

6 July
0200 H Set all clocks ahead to minus nine zone time.

8 July
0130 I During period of transit to the BARRIER, conducted daily
        training dives, fire control problems and adjusted and
        fired all guns.

1230 I SJ radar went out of commission. This was the beginning
        of radar troubles which continued throughout the patrol.
1858 I SJ radar back in commission.
1955 I Sighted what appeared to be two merchantmen bearing 067°(T),
        range 9 miles, coming out of the horizon haze. Latitude
        18°- 58' S - Longitude 115°- 17' E. Changed course to
        the Westward to avoid being sighted and to clear the
        area. Just as darkness set in, with the range opening nicely,
        range began to close rapidly. From a range of 26,000 yards
        it fell to 18,000 yards, so at
2013 I Fired proper identification flare. Contact changed course
        to West and range began to open steadily. I believe that
        we were not sighted prior to darkness, that the contact
        picked us up when he manned his radar and that he was an
        escort vessel for merchant traffic from DARWIN headed West,
        since at one time he tracked at 25 knots. Sent no contact
        report since identification flare worked and we were cross-
        ing convoy lane from DARWIN to the West at time of contact.

9 July
1430 I SJ radar out of commission again.
1600 I SJ radar back in commission.
2015 I SJ radar out of commission.

10 July
0015 I SJ radar back in commission.
1346 I Having planned to transit LOMBOK STRAIT tonight and having
    arrived at point FLAG, submerged to await darkness.
2050 I Surfaced and set course for LOMBOK STRAIT.
2225 I "XCV" contact on 190 mcs, 980 prf, believed one of the air
    search stations on BALI.
2238 I Number 4 main engine out of commission with two broken
    cylinder head studs and at
2301 I Number 2 main engine went out of commission with a bro-
    ken cylinder head stud. Decided to remain sout of the
    BARRIER until I had at least three engines. SD radar was
    discovered to be out of commission.
2302 I "XCV" contact on 153 mcs, 500 prf, definitely established
    as air search on BALI. Neither of these "XCV" contacts
    remain on for any length of time.

    It was on this day I discovered that we had a case of
    mumps aboard. This case had originally been diagnosed
    as parotiditis but when orchitis complications set in,
    the original diagnosis went by the board. Upon invest-
    igation I found that there were 27 men and 2 officers
    susceptible on the 28th of July. Because of wrong dia-
    gnosis in the first place, it was useless to isolate
    the case for all of the above men were exposed. How-
    ever, if all of them contracted mumps, I would still
    have two full sections to work the ship.

11 July
0300 I Number 2 main engine was put back in commission. It was
    now too late to begin transit of LOMBOK and still make it
    before daylight so decided to spend this day south of the
    BARRIER to repair #4 main engine and SD radar.
0730 I Submerged.
1600 I Number 4 main engine back in commission. By the time we
    had checked all cylinders, found four broken studs.
2018 I Surfaced. SD radar still out of commission.
2032 I "XCV" contact at 180 mcs and lost it 2 minutes later.

12 July
0255 I Began transit of LOMBOK STRAIT.
    Picked up Jap air search radar on BALI which continued
    intermittantly during the passage of the strait.
0333 I Picked up 10 cm radar interference which appeared to be
    located on the southwest corner of LOMBOK. This radar
    steadied on us during a good part of the passage. My
    experts claimed that this interference was not one of
    ours.
0417 I Picked up SJ radar interference bearing 230°(T).
0441 I Completed transit of LOMBOK STRAIT and set course for
    KANGEAN ISLAND. I plan to patrol submerged south of

12 July
0441 I (Continued)
        KANGEAN today in order to check the other engines and att-
        empt further repairs to SD radar.
0640 I Submerged.
1139 I Sighted U.S. submarine, which appeared to be the BLENNY, on
        a north-westerly course.
2039 I Surfaced and headed up to pass between the reef west of KAN-
        GEAN. I plan to patrol northwest of KANGEAN tomorrow on
        traffic lane from SURABAYA to KANGEAN.
2333 I Sent my posit to the BLENNY and requested instructions, also
        telling him that my SD was out of commission. No reply from
        BLENNY.
2345 I Completed first passage through the reef.

13 July
        During the night picked up various SJ contacts from 2,800 to
        3,400 yards, all determined to be second return echoes.
0642 I Submerged for day's patrol.
2035 Surfaced with SD still out of commission.
2039 I "XCV" contact at 140 mcs, 1300 prf, 7.5 microseconds. Source
        undetermined.
2216 I Again sent posit to BLENNY and requested instructions.
2333 I Received message from BLENNY telling me to rendezvous.

14 July
0002 I Told BLENNY I would arrive at rendezvous at 0130 I.
0144 I Began to talk with BLENNY on VHF.
        Discovered his troubles with main motors and told him that I
        had seen nothing to date. We decided to remain near each
        other until LOGGERHEAD passed through and procure information
        on the area from him before making plans. I also learned
        that it was his SJ interference I saw near LOMBOK on transit
        of the strait.
0512 I Made radar contact on LOGGERHEAD. Remained in vicinity until
        he had rendezvoused with BLENNY and then closed BLENNY. Rec-
        eived orders to patrol between KANGEAN ISLANDS and BALI and
        west to MEINDERT'S REEF. Began transit for second time
        between the reef following behind the LOGGERHEAD.
1100 I Began surface patrol on traffic land between MEINDERT'S
        REEF and KANGEAN.
1130 I SJ radar out of commission.
1440 I Aircraft contact #1, Lat 7-38 S Long 114-54 E, bearing 231°
        (T), range 10 miles headed north. Plane identified as fighter
        type. Plane turned toward and headed in so at
1441 I Submerged.
2122 I Surfaced. Began patrol of same traffic lane during moonlight
        and headed toward coast of BALI at moonset for patrol along
        coast.
2252 I "XCV" contact at 110 mcs. Source undetermined.

15 July
0230 I SJ radar back in commission.
0605 I Received message from the BLENNY which was not decoded
        until after
0628 I When we submerged for the day's patrol. The message
        from the BLENNY ordered us to patrol station 10 miles
        south of a point 140°(T), 40 miles from GREAT MASEL-
        EMBO. Decided to complete torpedo routine and then
        head for new station.
1014 I Surfaced on four main engines headed for passage of
        the reef again.
1320 I Completed passage of reef.
1400 I SJ radar out of commission.
1540 I Air craft contact #2, Lat 6-17 S Long 114-50 E.
        Sight contact on "PETE" bearing 260°(T), distance 10
        miles. When he turned and started in at
1541 I Submerged. Bow planesman froze on his planes and the
        BOARFISH made a 30° dive. The Commanding Officer
        served as a buffer for the SJ receiver which broke its
        moorings and headed bottomward. Results; heavy scratches.
        Finally stopped by the old rule of "back and blow".
        Being at that time two miles south of assigned station
        decided to remain submerged until dark, taking observat-
        ions at 57 feet.
2040 I Surfaced and began north-south patrol on assigned station
        with SJ radar back in commission.
2130 I SJ radar interference which when challenged was identi-
        fied as BECUNA. The BECUNA was patrolling on station
        the BLENNY was to have had since she had gone westward
        earlier in the day after another contact.
2337 I Received message from the BECUNA that she had radar
        contact on a target course 090°(T), speed 19. His
        position placed us 25 miles south of him.
2345 I Increased speed and came to course 070°(T) to attem-
        pt to close. This is a long bet. With target bear-
        ing 205°(T) and making 19 knots my only hope is to
        catch the target if the BECUNA drives him
        south.

16 July
0008 I BECUNA sent message asking where we were. I think our
        reply reassured him.
0033 I BLENNY sent course, speed and position of his contact
        which was too far for me to follow. My best bet is to
        follow BECUNA contact.
0134 I BAYA reported that he had contact on the target.
0201 I BECUNA reported that he had attacked and 10 minutes
        later reported no hits.
0250 I Regained SJ radar interference with the BECUNA.
0309 I Saw a heavy flame-laden explosion over the horizon
        bearing 020°(T). It looks as if someone got him.

16 July (Continued)
0350 I BAYA reported that his attack had been completed and that
    he had sunk a torpedo boat. The chase was over. Being
    now almost north of SEKALA decided to go east of it to my
    patrol area, so at
0545 I Came to south and headed back.
0740 I Aircraft contact #3, Lat 6-29 S Long 116-23 E. SJ Si ht
    contact on "PETE" type float plane bearing 210°(T), range
    3 miles. Submerged. SD still out of commission.
1011 I Having given Pete time to complete his patrol,
1428 I Aircraft contact #4, Lat 7-21 S Long 116-03 E. SJ Si ht
    contact on "PETE" type float plane, bearing 325°(T), range
    10 miles. Submerged.
2030 I Surfaced and headed for MEINDERT'S REEF.
2345 I Sighted object on horizon, SJ unable to pick up contact,
    and began to close. Turned out to be a fishing boat.
    On visual contact he was over 10 miles away. Visibility
    on these nights exceptional. After looking over headed
    south for BALI coast.

17 July
0325 I Made SD contact on BALI at 14 miles. For the first time
    in the area the SD is working. By tuning and changing
    frequency we finally got a land echo at 72 miles.
0628 I Submerged for day's patrol. Began patrol of north coast
    of BALI, five to six thousand yards off the coast.
2044 I Surfaced. Contact: One fisherman fishing.
2350 I Received message from BLENNY ordering us to patrol 6 miles
    north of MEINDERT'S REEF and to patrol vicinity of 7-30 S
    and 115 E at night.

18 July
0740 I Sighted MEINDERT'S REEF and began patrol on assigned sta-
    tion.
0849 I Aircraft contact #5, Lat 7-23 S Lon 114-36 E. SD radar
    on unseen plane at 6 miles. Closed to 4 miles. Submerged.
0852 I One bomb; not close. Decided to patrol my station sub-
    merged for remainder of day.
2029 I Surfaced and moved out to patrol assigned night station.

19 July
0145 I Exchanged calls by SJ radar with BESUGO, after having his
    interference most of the evening. Told him that I would
    patrol east of TG. BUNGKUALAN for the day and he said he
    would be west of this point.
0210 I Headed for BALI coast.
0546 I SJ radar made contact at 6,700 yards, bearing 205°(T).
    The range closed very rapidly to 4,800 yards and bearing
    changed 30° in one minute. OOD, thinking this a plane
    contact, submerged. It was later discovered that the sec-
    ond true bearing was read in error. Levelled off at 150
    feet, sound picked up li_ht, very fast screws on original

19 July
0546 I (Continued) bearing of contact. These screws passed
        overhead almost immediately and one minute later were
        lost. On coming to periscope depth, target could not
        be located in the twilight. It is possible that this
        was a motor torpedo boat, because of the high speed,
        very fast propeller beat and short initial range on
        contact. Continued on submerged patrol off the coa-
        st of BALI from 2,000 to 6,000 yards off shore.
2038 I Surfaced. Decided that I would patrol traffic lane
        between MEINDERT'S REEF and KANGEAN tonight and
        spend tomorrow patrolling south of MEINDERT'S REEF.
2044 I "XCV" contact at 160 mcs, 500 prf, 7½ microseconds
        which was probably air search on BALI.

20 July
0620 I Submerged for day's patrol south of MEINDERT'S REEF,
        making observations at 57 feet.
0939 I Aircraft contact #6, Lat 7-40 S Long 114-40 E. Sigh-
        ted single engine fighter type plane, bearing 194°(T),
        distance 5 miles. This fellow evidently making an A/S
        sweep along the coast of JAVA and BALI.
2028 I Surfaced. No contacts during the day. Began transit
        past the reef once more to patrol on the surface on
        possible traffic lane between GREAT MASELEMBO and
        SURABAYA tomorrow. I have been sighted five times by
        planes and believe that they may be holding up traffic
        on that account.

21 July
0231 I Completed transit of passage through the reef.
1156 I Sighted two masted sailboat through the high peris-
        cope, bearing 071°(T) and changed course to close.
1407 I Had sailboat alongside. No cargo unless the popul-
        ation of 17 men, women and children are considered
        cargo. Distributed largesse and continued patrol.

22 July
        Shifted to surface patrol along traffic lane between
        south coast of BORNEO and SURABAYA via BAWEAN ISLAND.
0506 I Submerged to flush out #4 MBT.
0559 I Surfaced and continued surface patrol.
0903 I Sighted another sailboat on horizon bearing 080°(T) and changed
        course to investigate.
0954 I Had sailboat alongside. No cargo. This encounter was
        very interesting. As soon as I had closed sufficiently
        for the crew to identify the ensign they hung a big rag,
        supposedly white, on the rudder post. They all ducked
        into the deck cover and soon emerged arrayed in brightly
        colored shirts where before a ragged pair of trousers
        had been sufficient. Then being properly attired they

22 July (Continued) all manned the rail and came to a snappy
0954 I salute until we were alongside. On finding the boat
empty, except for their fishing gear, gave them each a
pack of cigarettes. Nothing would do but that we should
be given a cocoanut in return. It was a friendly gesture
indeed. Continued patrol.
1624 I Aircraft contact #7, Lat 5°-00 S Long 112°-26 E. Made
sight contact on "PETE" type float plane, bearing 110°(T),
range about 7 miles, headed in. Submerged.
2043 I Surfaced patrolling on same routes as before.
2258 I Believing CHUB to be in the area by this time, sent my
position and requested instructions.
2328 I Received message from CHUB ordering rendezvous.

23 July
0146 I Rendezvoused with CHUB and received instructions via line
throwing gun. At the rendezvous were the CHUB, BOARFISH
and a single masted small, prau. He was not concerned in
the least by our being there.
0245 I Completed rendezvous with CHUB and set course for tomor-
row's patrol between BAWEAN and SURABAYA.
0750 I Submerged for day's patrol.
2044 I Surfaced. Planned to go back to surface patrol north of
BAWEAN ISLAND tomorrow and if nothing shows up to patrol
down toward SEMARANG.

24 July
1620 I Sighted possible torpedo wake passing astern. Lat 5-02 S
Long 112-30 E. Maneuvered to put probable submarine
astern and cleared immediate vicinity.
1832 I Sighted sailboat on horizon bearing 160°(T). Closed to
investigate. No cargo.
2100 I Set course for KANGEAN ISLAND, with intention of patrolling
northwest of that island tomorrow.

25 July
0026 I Received serial 43 ordering lifeguard duty for the BOAR-
FISH on 29th, 30th, and 31st. off SINGAPORE.
0620 I Received serial 47 which gave a change to the reference
point for one of my plane-life guard days.
0630 I Informed CHUB that I was patrolling northwest of KANGEAN
ISLAND today.
0651 I CHUB sent message that he would be southwest of KANGEAN.
0958 I Submerged for day's patrol.
2047 I Surfaced. No contacts during day. Allowing six hours
submergence for plane contacts and part of a day in
KARIMATA STRAIT submerged, I must leave this vicinity

26 July
0441 I Sent BOARFISH first acknowledging orders for life-guard
          duty.
1645 I Received serial 54 giving BUMPER information of life-
          guard stations and for me to note the change in the
          set up.

27 July
0717 I Began transit of KARIMATA STRAIT.
0840 I Was six hours ahead of schedule and not wanting to pass
          KARIMATA in daylight, submerged in strait until dark-
          ness.
0111 I Surfaced.

28 July
0028 I Received serial 62 with the information that the strike
          on the 30th had been cancelled.
0119 I Completed transit of KARIMATA STRAIT.
1224 I Crossed equator at longitude 106°-48' E.
2229 I Told LIZZFISH that I was relieving him and received
          message that he was departing area.

29 July
0600 I Arrived on station for life-guard duty.
0720 I Received serial 69 saying that there would be another
          Liberator in the strike today.
0925 I Submerged for trim dive.
1015 I Surfaced and began patrol at assigned reference point.
1630 I Having had no business for today, headed up to look over
          the ANAMBAS ISLANDS until dark and then head for assing-
          ed rendezvous position with the BUMPER.

30 July
0127 I Rendezvoused with BUMPER and received mail. The BUMPER
          had no instructions as regards new area assignment so at
0245 I Upon completion of rendezvous set course for area D-1.
0427 I Sent BOARFISH second reporting that I had been relieved
          by the BUMPER and that I was now an area orphan. Req-
          uested permission to join the BLENNY pack off PULO
          TENGGOL.
1000 I Received serial 78 telling us to join BLENNY pack until
          6 August and then head for SUBIC.
1335 I Received message from BRILL asking that I rendezvous with
          him. Headed for his position.
1804 I BRILL came alongside and transferred his two Indonesian
          volunteers to the BOARFISH.
1812 I BRILL underway from alongside and stood to the southward.

30 July
2200 I Sent a message to the BLENNY telling him that I was re-
     porting to him for instructions and that I had passengers
     aboard from the BRILL.
2330 I Received orders from BLENNY to patrol in vicinity of
     REDANG ISLAND.
     Decided to cover northern and eastern approaches to these
     islands submerged tomorrow.

     On this day the second case of mumps appeared. We have
     been lucky that there has been only this one. However,
     on arriving in port this will make us quarantinable.

31 July
0836 I Submerged for day's patrol.
2132 I Surfaced. No contacts during day. Headed in toward
     MALAY coast for inshore patrol. This was never accomp-
     lished because BLENNY told me to investigate REDANG ISLAND
     for possible shipping.

1 August
     Having completed a sweep of the northern island and find-
     ing the northern harbor on REDANG empty, set course for
     southern harbor when at
0445 I Made sight contact on unidentified object which challenged
     us with a blinker tube. This was BLENNY who we knew had
     just completed a sweep of the southern section. Exchanged infor-
     mation via VHF on the islands and results to date. Headed
     back for my patrol station, outer and northern approaches
     to REDANG, after receiving instructions from BLENNY.
0759 I Submerged for day's patrol.
2150 I Surfaced and headed in once more for inshore patrol along
     MALAY coast, when at
2248 I Received message from BLENNY to proceed to south of PULO
     TENGGOL and assist in search for COD's boarding party.
     Set course accordingly.

2 August
0015 I BLENNY told me to cancel his last orders and proceed to
     rendezvous with COBIA for transfer of passenger and
     ammunition.
0030 I Set course for rendezvous point.
0445 I Exchanged calls by SJ radar with COBIA, and at
0532 I COBIA came alongside to starboard and began transfer of
     Lieutenant Francis DRAKE, RANVR, 120 rounds of 5" ammu-
     nition and 208 rounds of 40mm ammunition for the BLENNY.
0615 I COBIA underway from alongside and stood to the southward.
     The only casualty of this exchange was a dislocated finger
     suffered by the Executive Officer as he was assisting in
     the handling of ammunition.
0630 I Told BLENNY that I had Lieutenant DRAKE and Ammunition
     aboard.

0725 I BLENNY sent instructions to join the COD search group
south of PULO TENGGOL. Set course accordingly.
0930 I Received orders from BLENNY to search north of PULO
TENGGOL. Began box search north and northeast of
PULO TENGGOL.

3 August
0002 I Received orders from BLENNY to rendezvous with him
east of PULO TENGGOL.
0131 I Received serial 5 telling BOARFISH to work under BLENNY
in search of COD boarding party.
0340 I Made contact with BLENNY and COD. It was decided to
transfer passenger and ammunition via breeches buoy so
BLENNY closed to pass over his gear. After having gear
aboard, COD closed and breeches buoy gear was rigged.
However, constant binding of the block was slowing down
operations and I accordingly asked the COD to come
alongside.
0555 I COD alongside to port. Completed transfer of Lieutenant
DRAKE and 48 rounds of 40mm ammunition.
0601 I COD underway from alongside.
0622 I Began rigging of breeches buoy to BLENNY. As soon as
gear was rigged, commenced passage of ammunition.
0815 I Aircraft contact #8. Lat 5-30 N Long 103-42 E. while
still passing ammunition, made sight contact on un-
identified aircraft, bearing 085°(T), range 15 miles.
Continued passing ammunition. This plane was headed
north and agonizingly slowly he passed out of sight.
The man in the shears, standing by to butcher knife the
hawser, was fairly crying to perform.
0850 I Transfer of ammunition completed, BLENNY stood to south
and BOARFISH to search north and east of PULO TENGGOL.
1321 I Received orders from BLENNY to discontinue search and
carry out previous instructions. He had recovered COD
boarding party.
It had been decided that I could spend two nights and
a day south of REDANG ISLANDS but that someone should
guard the off shore area on the chance that something
came through.
1325 I Decided to go in and have a look at the area north of
REDANG ISLAND and then head south. Set course accord-
ingly.
1810 I Sighted a junk on the horizon which at
1850 I Boarded and investigated. No cargo. The master of
this craft was a Chinaman, as were all of the crew. He
spoke excellent English and was only too happy to see
us leave him with his junk still in one piece. He did
not volunteer to accompany us. Set course at twilight
for inshore patrol south of REDANG ISLAND.

0216 I Received contact report from BLENNY that he had target
      giving position, course and speed. Set course to arrive
      at target's 0300 I position.
0242 I SJ radar contact bearing 230°(T), range 5,000 yards. Man
      gun stations. When radar operator changed pulse rate
      found my target was second return echo. Secured from

0250 I BLENNY sent message that his attack was completed and
      that he was making an end around on target. Began end
      around on BLENNY.
0522 I BLENNY reported target was alerted, shooting his gun and
      that BLENNY was breaking off attack. Set course for
      patrol station 6,000 yards off beach between PULO TENGGOL

      tact with same target and then, if it is too small for
      torpedoes to "Battle Stations Gun" and attempt to sink
      it.
0724 I Submerged for day's patrol.
2150 I Surfaced. During day we have had a beautiful view of
      MALAY coast but no shipping.
      Patrolled during the night close into shore off MALAY

C. WEATHER

     The weather was as expected for this time of year. In the
JAVA SEA the wind was predominately from the south east. Three
days during two weeks were so overcast that no star sights or
sun lines could be taken. Near PULO TENGGOL we encountered the
usual rain squalls, but no overcast except on 6 August. The
wind in this area was from south west as shown on Hydrographic
Publications. SOUTH CHINA SEA area was generally overcast
probably caused by the typhoon to the north.

D. TIDAL INFORMATION

     No tidal effect was noticed at any time. In the JAVA SEA
the set was easterly at .5 to 1.0 kt. as shown on current tab-
les. In KARMATA STRAIT and SOUTH CHINA SEA the set was north-
erly at about 1 kt. No current existed when close to shore
north of PULO TENGGOL but 30 miles off shore there was a north-
erly set of about 1 kt.

E. NAVIGATIONAL AIDS

     None were seen to be in operation. The light house at
MEINDERT'S REEF was picked up by SJ at 15,000 yards, but it
was not lighted.

F. SHIP CONTACTS

     No ship contacts were made except on native sailing craft.
The contact on 8 July is not listed since it was friendly
shipping.

H. ATTACK DATA
No attacks were made.

I. MINES
No mines or mine sweeping activity were encountered.

J. ANTI SUBMARINE MEASURES AND EVASIVE TACTICS
It is evident that the Japs are flying two patrols daily
in the eastern JAVA SEA. I believe this patrol confines its
activity almost entirely to the area enclosed by BALI and
KANGEAN ISLAND as far east at 116°E. Only one bomb was drop-
ped on us and the pilot's aim was poor.
After being driven down in the morning on 5 August, there
was a plane search of the area again that afternoon. The
next day a search of 3 fighters was used. It seems that the
increased submarine activity near PULO TENGGOL has caused
the Japs to start an A/S air search in this area. Another
possibility is that a spotter is located on PRINTIAN
ISLAND and that he called out the dogs when I began surface
patrol in that area. A careful search of these islands pre-
viously had indicated no human inhabitants.

K. MAJOR DEFECTS AND DAMAGE
(a) On 10-11 July four cylinder head studs on #4 main
engine and one on #2 main engine broke. It is believed that
this was caused by excessive tension on the cylinder head
studs. Tensions on cylinder head studs were not taken before
leaving port, therefore this casualty may be attributed solely
to operating personnel. Steps have been taken to prevent a
repetition of this casualty.
(b) Despite continued efforts to stop the conning tower hatch
from leaking, the leakage is becoming worse. It is believed
that the only solution is an entirely new hatch and facing
down of the knife edge if necessary.
(c) The bow planes have developed an excessive rumble in
both power and hand operation which definitely decreases the
possibilities of evasion by silent running.

L. RADIO
Reception of NVB was generally good to excellent and no
serials were missed. Reception was best in the JAVA SEA area
where an S-5 signal was usually obtained and the Jap broad-
cast stations which provide most of the interference were
comparatively weak. In the SOUTH CHINA SEA the miscellaneous
stations near NVB frequencies came in stronger, but NVB was
still S-5. The VIXØ rebroadcast was picked up with no trouble
in the JAVA SEA area. 925Ø kcs was the most used frequency
with good reception except for short periods around 2ØØØ GCT.

- 17 -

— page 143 —
CONFIDENTIAL
L. RADIO (Continued)

Atmospheric interference on 4370 kcs were usually too high
for copying. 12630 kcs was used during the daytime occasion-
ally with good results.
Communications on the Wopaco frequencies were 'generally'
reliable with only minor interference. C.W. was used exclus-
ively.
VHF communications with other submarines was effective at
2 miles range. No opportunity was presented for communication
with aircraft.
On both ship-shore transmissions VIX0 answered the initial
call-up which was made to NPTl, and the messages were cleared
to VIX0 with no difficulty.
There were no materiel failures.

M. RADAR SJ-1

1. Performance

The SJ-1 radar was modified during refit to include
IFF challenge and response, but there was no occasion to
utilize this feature during this patrol. After repairing
a series of major casualties, which ultimately resulted
in a complete refit overhaul, this equipment gave excell-
ent results the remainder of the patrol. The following
maximum ranges were recorded:-
Range Target Night or Day
240,000 yds. Bali (10,000') Night
14,000 yds. Submarine Night
6,700 yds. MTB(Possible) Night

SJ radar communication was used on all exchanges of rec-
ognition signals and call signs with other U.S. submarines.

2. Operational Casualties:

The SJ radar functioned normally (ringtime 5,500 to
5,900 yards) for 32 hours operation time after departure
from Fremantle. At this time, the main power fuses had
to be replaced. At the end of 40 hours operation the SJ
failed completely with the following symptoms: Loss of
various plate and screen voltages, loss of sweep, loss of
crystal current. The following repairs were necessary to
restore equipment to normal operation:-
A. Transmitter-Receiver Unit: Replace R-36, C-21, R-47,
one 705A, one 807, one 6V6, one 6SN7, one 5D21.
B. "A" Regulated Rectifier: Tubes replaced; 5V4G(2),
6Y6G(4); 6SQ7(2); and two VR tubes.
C. Range Unit: Replaced regulator lamp, Lp-4.
D. PPI Unit: Replaced CRT 5FP7.
E. Main Control Unit: Replaced 500v DC meter for regulate.
rectifiers; fuses.

CONFIDENTIA
M. RAD at SJ-1

2. Operational Casualties: (Continued)

It was now noticed that when the SD-5 was keyed the
sweep on the "A" scope would shorten in length and lose
brilliancy. Both ends of sweep would move in towards
the center.

Six days later, after 120 hours of operation, all
sweeps failed. Cause was traced to a bad IF strip in
the range indicator unit. Eight plates and screen res-
istors were replaced as well as V3 and V4.

Lobe separation failed after 126 hours operation and
was remedied by replacing V2.

After 140 hours operation, a 115v ground was reported,
and traced to terminal #19 in the Conning tower box. The
surrounding insulation was badly charred; the leads (six
in all knew!) were fused together, and the holding screw
was finger tight. It is believed that the majority of the
above stated failures were due to this glaring example of
poor wiring, causing surges of voltage throughout the
equipment. Circuit tracing indicated that this wiring
had been done during the installation of the ST Radar
during the last refit. Two spare terminals, connected
by a jumper wire were used to remedy this condition.

During the next 10 hours operation it was noticed
that when shifting from ST operation to SJ, the later
unit would drift in IF frequency for 15 to 20 minutes,
requiring retuning two or three times before a stable
condition was reached. Both 717A tubes and the BO
tube were replaced before normal operation was restored.

Other minor casualties were as follows:

1. TR cavity arcing, badly due to improper tightening
of cavity. TR tube replaced, cavity adjusted properly.
2. Loss of high voltage gaseous 836 rectifier tube
replaced.
3. "B" rectifier maximum voltage output 260v. Replaced
VE tube and two 6SQ7's. Voltage output now 290v, un-
able to get required 300v.
4. Loss of sweeps traced to low amplitude synchronizing
pulse. Replaced V3 (on time multivibrator). Sweeps
restored.

SD PERFORMANCE REPORT

The SD-5 radar was used throughout the patrol, utilizing
its keying feature while in the patrol area, however, only one
plane contact was made. Operational failures were a constant
headache.

The first indication of poor performance was noted in fail-
ure to pick up LOMBOK when within 50 miles. In previous pat-
rols, this unit gave ranges on LOMBOK up to 80 miles.

The entire gear was overhauled, tubes checked, and restored
to operation, but sensitivity was still low. After two days
of checking; replacing tubes; and measuring circuit valves, a
peak pip was finally obtained on BALI. This was the first in-
dication of land we had picked up since leaving Fremantle.
Receiver tuning was again adjusted until land echoes were ob-
tainable at 72 miles. Two days later, we again failed to pick
up land echoes. A very faint arcing was heard in the receiver
unit and was finally traced to a "rosin-solder" joint from the
input jack to the tank input of the first R.F. section. After
resoldering this connection, the SD-5 was returned to normal
operation. This connection, on previous checks, had shown con-
tinuity, but evidently offered high impedance to R.F. and was
not allowing the return signal to pass.

On three occasions, "grass" failed to appear on the sweep.
The first time due to dirty contacts on the keying switch, in
the remaining cases, due to bad IF tubes. Replacement of the
third IF tube in the receiver removed spurious oscillations
that were drifting across the scope on another occasion.

Two sweep failures were traced to faulty 2x2 tubes in the
CRT power supply.

IFF equipment was used in conjunction with the SD while on
life guard station but no contacts were made to check performance.

On two separate nights, a light bluish RF spark about 2½
inches long was seen emanating from the tip port antenna whip,
when the SD was keyed. This was attributed to humid atmospheric
conditions in the area.

ST RADAR PERFORMANCE

The ST radar was installed during refit at Fremantle, but
due to lack of contacts, no statement can be made about its
performance under approach conditions. By comparison, on land
contacts, recorded ranges were about 1/2 those obtainable with

- 20 -

M. RADAR ST PERFORMANCE (Continued)

the SJ-1. However, we obtained one range of 32,000 yards on
land on the surface. No operational casualties were exper-
ienced. It is felt that poor wiring technique during instal-
lation caused a greater part of the serious casualties in the
SJ-1 unit. In addition to the casualties caused, wiring was
shifted throughout the unit and no endeavor made to properly
tagged leads or junction. A new wiring diagram was not fur-
nished by the refit activity with the result that the ship
had to draw its own.

APR - 5AX EQUIPMENT

Interception of enemy radar transmission was frequent
in the EAST JAVA SEA area, most contacts being identified
as land-based radar. Two or three contacts made were
thought to be Jap aircraft or Jap ship-borne radar, but
the signals were, at best, very weak, and eventually faded
out. The 5-AS unit (1,000 - 3030 mcs) failed to intercept
any signal, in spite of frequent SJ interference on our SJ
A-scope. It is believed that the coax antenna lead to this
unit attenuates incoming signals and that a wave guide is
necessary to insure proper operation.

IFF EQUIPMENT

Both the BN and ABK units functioned normally when used,
but no U.S. aircraft contacts were made to definitely prove
their proper operation. One test was run with the U.S.S.
COBIA while at close range, but only an erratic, sketchy
return pulse was visible on the SD. The IFF switching relay
for BN use with the SJ is poor in operation and tends to
stick open. Cleaning and tension adjustment have failed to
eliminate this trouble.

N. SOUND GEAR AND SOUND OPERATIONS

1. Performance:
All sound gear functioned normally with no material
failures. Lack of targets preclude maximum ranges. Surf
noises were picked up at 12-14 miles in the JAVA SEA and the
GULF OF SIAM. The usual fish and shrimp noises were picked
up in both areas.

2. Operational Casualties:
Loss of main power on the JP on one occasion, resulted
in the loss of several minutes operating time, as it was nec-
essary to send a man into the forward battery well to replace
a blown fuse. A fuse rack adjacent to the JP gear should be
installed to remedy this situation.

SOUND GEAR AND SOUND OPERATIONS (Continued)

2. Operational Casualties: (Continued)
     The JK-QC projector shaft causes considerable vib-
ration and howling while being trained due to packing bind.
This also results in excess leakage around the shafting, at
depths of 100 feet or more.

O. DENSITY LAYERS

     The only density layer encountered occured at Lat 6°-
10.9' S Lon. 102°-35.8' E, on 31 July, 1945. This negative
layer was located between keel depths of 70 feet and 75 feet.
Throughout all other dives in the JAVA SEA and GULF OF SIAM
no gradients were found. Bathythemograph cards are being
forwarded to V.C.N.O.

P. HEALTH, FOOD and HABITABILITY

(a) Health:

     Two cases of mumps developed. On 10 July the first
case appeared. This was originally diagnosed as mastoiditis
because the swelling was in that area. When orchitis devel-
oped there was no question as to the nature of the contagion.
There were 27 men and 2 officers exposed. On 30 July the
second case of mumps appeared. None of the other exposed
personnel contracted the disease.

     Two cases of catarrhal fever developed.

     On 2 August the Executive Officer dislocated his finger
while handling ammunition.

     On 7 August, while shifting torpedoes in the forward
torpedo room, a torpedoman's mate caught his ear between two
skids. A large section of the earlobe was almost torn away.
The segment was sutured on in hopes that it could be saved.
Final diagnosis will have to be made on entry into port.

     The loss of services of the above mentioned personnel
put a strain on our organization. Carrying only 74 men leaves
no spares in case of sickness or disability.

(b) Food - The food was good and adequately prepared.

(c) Habitability - Living conditions were excellent
throughout the patrol. The acquisition of some late issue
movies was very welcome. Playing the same Armed Forces trans-
criptions for three patrols is becoming tiresome. It is
hoped that we can get some new records before going on the
next patrol.

V. REMARKS

     (a) No minesweeping activity was noted.
     (b) With the exception of native sailboats no enemy traffic
         was encountered.
     (c) No trouble was had in routining Mk. 14 or Mk. 18 torp-
         edoes.
     (d) It is believed that the ballasting of this vessel be
         investigated. Upon departure from the area, there was
         5,000 pounds or less in each of the variable tanks.
         To keep this much water in these tanks it was necessary
         to run with two fresh water tanks empty. If the patrol
         had lasted longer it would have been necessary to use
         safety tank as a trim tank.
         Seventeen thousand pounds of topside ballast were
         removed before this patrol began. When the second 5"
         gun is installed this ballasting situation will be
         aggravated.
         Upon departing from the GULF OF SIAM the trim
         condition improved with denser water so that at the
         end of the patrol there is an average of 12,000
         pounds in each trim tank.

FIPST ENDORSEMENT to
U.S.S. BOARFISH (SS327)
Report of Fourth War Patrol.

From: Commander Submarine Squadron Twenty-two.
To : Commander in Chief, United States Fleet.
Via : (1) Commander Submarines, SEVENTH FLEET.
(2) Commander, SEVENTH FLEET.

Subject: U.S.S. BOARFISH (SS327) - Report of Fourth War Patrol.

1. The BOARFISH, under the command of Lieut. Comdr. E. C. Blonts,
departed FREMANTLE, Western Australia, 5 July 1945, on her Fourth War Patrol.
From 12 July to 28 July, the BOARFISH patrolled in the JAVA SEA off the north
coast of BALI and JAVA in a coordinated patrol directed by the Commander
Officer of the BLENNY. No enemy contacts were made, except planes, one of
which dropped a depth bomb on 8 July, no damage. BOARFISH performed life guard
duty for Allied Air Force strike over SINGAPORE on 29th. Remainder of the
patrol was spent in assigned areas off the MALAY COAST with no contacts.
Conducted a search for stranded COD boarding party which was rescued by the
BLENNY on 3 August. Departed area 6 August, arriving SUBIC BAY, P.I., 10
August 1945, completing a patrol of thirty-five days of which twenty-seven
days were spent in patrol areas.

2. Difficulties with SD and SJ radar, together with increased enemy
plane activity, undoubtedly handicapped the BOARFISH in effective area coverage.

3. The threatened epidemic of mumps due to the large number of ex-
posed men necessitated a quarantine of officers and crew during the first ten
days of the rest period.

4. The BOARFISH will be given a normal refit by the Relief Crew of
Division TWO HUNDRED TWENTY-TWO and U.S.S. HOWARD W. GILMORE. Docking will be
accomplished if dock is available to remedy high cavitation noise level of port
propeller.

5. The Commander Submarine Squadron TWENTY-TWO welcomes the officers
and crew of the BOARFISH on the completion of this war patrol and regrets no
opportunities were afforded to inflict damage on the enemy.
