HISTORY OF USS GUAVINA (SS 362)

During her six war patrols the submarine USS GUAVINA is officially
credited with sinking more than 32,000 tons of shipping which the Japanese
needed desperately to supply their war effort. In addition, the ship rescued
seventeen flyers who had been forced down in enemy waters.

Built by the Manitowoc Shipbuilding Company at Manitowoc, Wisconsin,
the submarine was named a fish found in the freshwater streams of the West
Indies and the Atlantic shores of Mexico and Central America. The ship's
keel was laid on 3 March 1943 and her launching took place on 29 August
1943. Miss Marie Moen, a Manitowoc resident, acted as sponsor.

USS GUAVINA was first placed in commission on 23 December 1943. Com-
mander Carl Tiedeman was the ship's first commanding officer.

After training exercises and trials on Lake Michigan, the submarine be-
gan her journey down the Mississippi on 16 January 1944. From New Orleans
she sailed to Pearl Harbor via the Panama Canal, making port on 12 March.
Her first war patrol began on 6 April 1944 when Commander Tiedeman conned her
out of the harbor and set her course for the Bonin Islands.

Refueling at Johnston Island, she was in position for her first attack
on 19 April, when she got off a snap shot at a small trawler. Heavy seas
caused the missle to run under the target and prevented any gun action.

Three days later the submarine came to battle surface to engage two
small trawlers. One of the vessels made good his escape, but the second was
sinking as GUAVINA left the area.

On the 25th, a large merchantman accompanied by one escort came into
view, and GUAVINA began a submerged approach. After reaching a position
only 580 yards away, she fired four stern torpedoes and swung for a bow shot
as the target changed course, thus avoiding the first torpedo spread. Three
of the bow torpedoes found their mark and GUAVINA went deep to avoid a
haphazard depth charging.

A convoy report from USS SAWFISH sent the sub out to intercept, and shortly
before sunrise five ships appeared. A zigzag threw the sub out of position
and so she surfaced to begin running around the convoy.

Diving, she waited for over an hour until the ships came into position.
Firing three torpedoes at the center freighter, the skipper heard three
tremendous explosions with the target engulfed in thick black smoke as he
swung for a shot at another cargo ship. Two explosions were then heard,
followed by a tremendous blast which shook the sub as she went deep to escape
depth charges.

Leaving her patrol area, GUAVINA proceeded to Wake Island, where she was
to perform lifeguard duty during carrier air strikes there. The planes
worked Wake over thoroughly on 24 May, as the submarine cruised leisurely five

— page 4 —

miles off shore, watching the show. No pilots were shot down in her vicinity,
and she arrived in Majuro on the 28th.

After a refit the submarine departed on 20 June 1944 for her second
patrol, to be conducted in the Palau and Yap areas.

Her first ship contact came on 3 July when a merchant ship, boxed in by
four escorts, appeared. Since she could not get into a good firing position
during daylight, she trailed the convoy until sunset and then ran ahead. At
0348 she fired four torpedoes, scoring three hits. As she lay deep for the
inevitable depth charging, the target could be heard breaking up as if he
were sinking right alongside.

A float plane caught her at periscope depth three hours later and
dropped eight bombs, but could not score. Taking up her lifeguard station,
GUAVINA waited for nine days before receiving word of a downed plane.

Proceeding to the scene of the crash, the submarine searched for 20
hours before finding the first three survivors. Another was located five
miles away. Lookouts spotted another bomber crashing on the 19th, and after
an all-night search eight men were taken aboard. The search for the remainder
continued until nightfall on the 21st, when she left for Seeadler Harbor,
Manus.

After disembarking her survivors and refueling, the submarine continued
to Brisbane, Australia for a refit, staying in port there until 16 August
1944, when she departed for her third patrol.

Two small coastal freighters evidently mistook GUAVINA's intentions
when she surfaced near them on the 31st. They immediately changed course
toward her, followed by natives who put out from the shore in small boats.
When the range closed to 3700 yards, the sub's gun crew disillusioned them
with a few well-placed shots. All the boats turned tail for the beach, but
both the freighters were sunk.

Sent to look for aviators reported shot down in the mouth of Davao Gulf
with no success, the sub rendezvoused with USS BASHAW to receive patrol
orders early in the month. On 12 September she sighted a small boat manned
by friendly Filipinos and let them pass.

One of the most thorough attacks on record followed when, on the 15th,
the smoke of a ship on the horizon attracted her attention. After waiting
in vain for the ship to come through Sarangani Strait, GUAVINA went in after
him, bucking a strong current as she went through the strait on the surface.
At 15,000 yards she dived to approach the transport, which was anchored in
a cove, evidently hiding from American planes.

After working her way in to 2000 yards, the submarine fired four
torpedoes, two of which struck the target aft, setting off a blast which
engulfed the entire after part of the ship, sending huge flames and black
clouds of smoke towering into the air. Working around to the ship's port
bow, she fired three more, one of which blew the target's bow off. Successive
torpedoes demolished the bridge, amidships and stern.

-3- USS GUAVINA (SS 362)

Surfacing 300 yards from the wreckage, GUAVINA cleared the area at
full speed, leaving what wreckage there was above water a jumbled, twisted
mass. Half an hour later a huge internal explosion lifted the remains into
the air, and they fell during in three separate masses of useless junk.

After a fruitless attack on a small trawler, the submarine refueled at
Seeadler and arrived in Brisbane on 28 September, where she remained for a
month before sailing for her fourth patrol.

Rendezvousing with BREAM to secure a spare radar part, GUAVINA continued
toward her area off Indo China. While in transit through Mindoro Strait on
the 15th she sighted a ship which had been set afire by carrier planes
during the day and added two torpedoes to sink her.

On the 22nd she sighted a Japanese merchant ship anchored in what seemed
to be a perfectly safe place -- inside the reef of Tizard's bank. Not to be
cheated of a good target, GUAVINA's skipper worked her around until he found
a spot where the reef was more than three feet deep and fired two torpedoes
from 3400 yards, causing two big explosions. Surfacing, she maneuvered for
a bow shot, but found it unnecessary when the target sank.

No one passed the word, evidently, because when the submarine inspected
the position again the following morning a large cargo ship was anchored in
much the same position. One long shot over the reef missed, and she
maneuvered around the island to a low spot and fired again. The heavy swell
caused the torpedo to broach, but a second ran true and hit the target squarely
between the stack and after mast. When the smoke had cleared away, the tar-
get had rolled over on its starboard side, sinking stern first. Only a small
bit of the bow, held up by the reef, was left above water.

Proceeding to Indo China, the ship carried out her next attack on 28
November when she fired three bow torpedoes at a cargo ship with only one
escort. A plane forced her to dive as she fired, and dropped an aerial
depth charge which made the ship "rattle like an old tin can." Two timed
hits were heard, followed by a big explosion as GUAVINA hit bottom.

Four tankers, prime targets for submarine warfare, crossed her sights
on 1 December, but the six destroyers escorting them kept her from pressing
an attack. After a week and a half of stormy weather, the subs threw an
offensive line from Camranh Bay in Indo China to the Dangerous Grounds off
Palawan.

The move paid off in a rich sighting three days later when a task force
of two battleships and two destroyers was sighted, but their plane coverage
prevented an attack.

After making a torpedo attack in stormy seas against a destroyer escort
without results, the submarine left for Fremantle. During her transit of
Lombok Strait the Japanese opened fire with a shore battery. Since the strong
rip tide prevented her diving, GUAVINA continued to run on the surface,
depending on radical maneuvers to throw the enemy gunners off. Soon the shells
were safely put astern and the sub arrived in port two days after Christmas.

Lieutenant Commander R. H. Lockwood assumed command of the submarine
during her refit, and on 23 January 1945, took her out in a coordinated search
and attack group with PAMPANITO, BECUNA and BLENNY.

GUAVINA first sighted a small convoy during the early morning of 7 Feb-
ruary, and moved to intercept a convoy of two ships with two escorts. Since
the bright moonlight would immediately spoil any attempt at a surface attack,
she submerged and waited until a course change gave her an overlapping target.

Firing six torpedoes, she made two hits on an oiler and one on a freighter
before having to dive to avoid a escort. Hitting the bottom near the stern
of the sunken tanker, she rested there for an hour and a half, listening
to the escorts in their vain search.

Teaming with PAMPANITO, she worked over a convoy the same evening. With
PAMPANITO on the enemy's starboard quarter, GUAVINA tried two approaches
without success and finally retired, firing four signal rockets to draw off
the escort. Taking advantage of his absence, PAMPANITO torpedoed her target
in the stern. The ship later blew up and sank.

Two tankers were seen on 20 February hugging the coast of Cape
Padaran and, after a long wait, the submarine blasted the leading ship with
three hits. Seeking the bottom again, she lay for seven hours as the Jap-
anese cris-crossed the area, dropping 98 depth charges.

Staying on patrol and plane guard duty until 3 March, the submarine
proceeded to Subic Bay, Luzon for her refit, arriving on the 5th.

On 21 March, after a refit alongside USS GRIFFIN, GUAVINA left for her
sixth war patrol, assigned an area in the South China Sea. On the 29th, after
a strike over Indo China, a crippled bomber was ditched alongside the sub
and five flyers were rescued.

GUAVINA left her area on 21 April, bound for San Francisco via Saipan
and Pearl Harbor. She arrived on 17 May and proceeded on to the Bethlehem Steel
Shipyard for an overhaul. She left San Francisco on 6 August and was en-
route to Pearl Harbor when the war ended. Departing on 6 September 1945,
she proceeded to Mare Island, California, where she was put out of commission
in reserve in January 1947.

The submarine was reactivated in April 1949 and converted to a submarine
oiler. As of August 1943 she is active, designated (AGSS 362).

B. NARRATIVE.

April 6, 1944
2030 (Z)-Underway from Submarine Base, Pearl Harbor, in
accordance with ComSubPac. Operation Order #121-44
dated 5 April 1944. Contacted escort P.C. 582 and proceeded via
prescribed routing to Johnston Island, training dives enroute.
Escort departed at dark on first day.

April 8, 1944
2330 (Z)-Arrived Johnston Island, received 14758 gallons fuel
oil, 668 gallons lube oil and departed three hours later. Proceed-
ing via prescribed routing to patrol area. Training dives and
drills enroute.

April 14, 1944
0525(Z)-In Latitude 25-58(N) Longitude 164-25(E) Sighted (Ship
contact #1), through high periscope, the shears of one
of our S/M bearing 190(T) distance 15 miles. Change of true bear-
ing indicated easterly course and drawing away. Was sure it was
one of our S/M returning from patrol so did not investigate further
and continued on to area.

April 17,1944
2320 (Z)-In Latitude 29-00(N) Longitude 147-50(E) made plane
contact #1. The plane came in to 20 miles on S.D.
Radar Screen and then went out. Never sighted lost contact nine
minutes later.

April 18, 1944
0930 (I)-Entered "WAITING AREA" (Latitude 29-30(N) Longitude
142-30(E)
0955 (I)-Dived.
1821 (I)-Surfaced.

April 19, 1944
0440 (I)-Dived.
0509 (I)-Sunrise. Wind and seas increased during morning so
that it was very difficult to maintain depth control.
1245 (I)-Surfaced, seas rough, wind force 7, sky completely
overcast, continued patrolling on surface. No fix
for 30 hours and navigation position a little doubtful so cruised
on various courses looking for "SOFU GAN" island for "land fall."
1700 (I)-With ship rolling and pitching a great deal S.D.
Radar showed "solid" contact at certain periods of
roll. Judged this to be the island we were looking for, at a
range of about 23 miles.

B. NARRATIVE (continued)

1808 (I)-Sunset.
1840 (I)-S.J. Radar contact bearing 335(T) range 17 miles.
1928 (I)-Sighted steady light bearing 345(T).
1930 (I)-Navigators evening stars indicated we were well to
north of area. Land we are heading for is TORI
SHIMA Island.

Several days previously Magnitron Tube in S.J. radar had been
renewed and its tuning was not exactly correct so we were closing
island to effect tuning. Echos on "P.P.I." screen very poor.
Nite dark and squally and visibility poor.

1938 (I)-Sighted ship (Ship contact #2) bearing 315(T).
Began swinging ship right for a stern shot. My
first impression was a big ship, range about 2000 yards but as we
were turning I realized it was a smaller ship at closer range.
Passed a beam about 700 yards. Continued swinging for stern shot.

1941 (I)-Fired three stern torpedoes, range 1500 yards angle
on bow 90 P. estimated speed 8 kts., ordered torped-
oes set at 6 feet.
S.J. radar ship to obtain range of target after first torpedo fired.
My estimate 1500 yards. Radar range 1500 so continued shooting as
I believed it a target worth 3 torpedoes. Target did not appear
to see us as he did not seem to maneuver. While waiting for "ex-
plosions" made close observation of target and then realized it
was a much smaller job than I first thought. It appeared to be a
trawler type, estimated length 200 feet, estimated tonnage 1000
tons.

1942 (I)-No explosions. Seas breaking over bridge. Consid-
ered a gun action was out of the question, so put
on all engines and headed south to get back in own area. Found
out later that torpedoes "went out" set at 10 feet instead of 6
feet as I had ordered. Believe the target was on patrol in the
area.

Sum total of action, three torpedoes wasted on a "Spit Kit".

2150 (I)-Back in own area.
2240 (I)-"S.J." radar contact bearing 242(T) 12,000 yards
This contact proved to be "SOTU CAN" Island so
tuned S.J. radar which proved to be badly out of adjustment.

April 20, 1944
0422 (I)-Dived.
0511 (I)-Sunrise.
1808 (I)-Sunset.
1824 (I)-Surfaced.

B. NARRATIVE (continued)

April 21, 1944
0000 (I) -Entered Area 14 Queen (Latitude 29-00(N) Longitude
          140-05(E)) starting the rotating patrol in accord-
          ance with "DUNKERS DERBY" rotation schedule riding "CAVALCADE".

0435 (I) -Dived.
0506 (I) -Sunrise.
1807 (I) -Sunset.
1822 (I) -Surfaced.

April 22, 1944
0330 (I) -Made S.J. radar contact (Ship contact #3) with two
          targets bearing 260(T) range 3200 yards. Turned
          away to start tracking and steered various courses to maneuver
          ahead. "Pip" was small and would fade out at 5000 yards so con-
          cluded targets were small. Tracking indicated course 155(T) speed
          12 kts. With thoughts of "wasted Torpedoes" on a Spit Kit" still
          in mind I did not want to waste any torpedoes on these as I was
          fairly sure they were small ships. At 5000 yards headed in but
          could not pick up ship until about 2000 yards, with binnoculars.
          Had decided on an early dawn gun action and had gun crews at stations.
          Targets in column about 3000 yards apart. Picked up leading target
          on port bow so turned to port bringing guns to bear. These were
          two "Spit Kits", Trawlers with a deck load of lumber and cargo.
          Estimated 150 feet long and displacement 475 tons. It was a dark
          morning and gun pointers could not see target in gun sight. Sea
          calm with long swells. Occasionally one broke over deck washing
          men about but this interfered little with gun action. Closed into
          1000 yards, then 750 yards before targets were sighted by gun crew.
          Opened fire to starboard Latitude 27-37(W) Longitude 141-46(E)
          with 4 inch, 20 M.M. and 50 cal. Target was very low in water and
          a difficult thing to sight on. At begining of shooting second
          target "turned tail" to northwest. Maneuvered at various speeds
          up to full, with range varying between 350 yards and 1800 yards,
          around target to keep guns bearing and avoid his attempt to ram me.
          The target did not return fire. In general the action was somewhat
          disappointing because even though it was point blank range the
          majority of 4" shell would hit in swells either in front or behind
          target. Fired 60 rounds 4" H.C., 10 rounds 4" common, 1080 rounds
          20 M.M. 700 rounds 50 Cal. Observed five 4" hits and ten probable
          hits in target's bridge and hull. The small arms were on target
          about 3/4 of the time. Still he would not sink although he began
          to stream oil and settle. He seemed to continue in a southerly
          direction.

0501 (I) -Sunrise.
0505 (I) -I decided to cease fire and clear area as I did not
          know the action of the other "Spit Kit" and thought
          he might have sent out a radio warning so cleared area to northwest.
          Put First Lieutenant on high periscope watch.

B. NARRATIVE. (Continued)

0515 (I)-As we cleared area the First Lieutenant was able to
observe target give a large puff of smoke, list to
starboard, completely settle and sink from sight. The second
target was then observed through the high periscope and appeared
to be approaching the area of our "expended Spit Kit".
The situation was clearly "Not too well in hand" but I had only
30 rounds of 4" common ammunition left and based on my previous
score I did not think the odds were worth the action and remember-
ing torpedoes I had wasted on the nite of April 19 I felt this
second target was not a torpedo "set up" so continued to clear
area.

Net result of action:
Sunk one (1) fishing trawler (475 tons).

0601 (I)-Dived. S.D. radar had been knocked out of tune and
as it was spotty clouds did not want to wait around
for any possible planes.
1807 (I)-Sunset.
1822 (I)-Surfaced.

April 23, 1944
0433 (I)-Sighted object bearing 075(T) which appeared to be
large ship. Dived to make approach as it looked
well inside horizon. As daylight approached, made out object to
be "SOFT CAN Island" which put us way north of area. This "upset"
our current prediction but at least provided us with a good, much
needed fix, so turned south to return to my area.

0503 (I)-Sunrise.
1807 (I)-Sunset.
1818 (I)-Surfaced and headed on course 270(T) to make a
sweep of the western part of my area.

April 24, 1944
0438 (I)-Dived.
0511 (I)-Sunrise.
0517 (I)-Surfaced. Plan to conduct patrol on surface today
to see if I can "drum up" some business while cover-
ing western part of my area, using S.D. Radar and
High periscope watch.
0615 (I)-Periscope observer sighted (ship contact #4) shears
and conning tower of a submarine, bearing 300(T)
range 15,000 yards (Latitude 28-51(N) Longitude 138-22(E)) on
easterly course. Was positive it was one of our own subs. Believe
it was HADDOCK.
0616 (I)-Dived and changed course to lead in for better look.
He did not come into view so assume he turned away.
0705 (I)-Surfaced. Sub not in sight. Continued surface patrol
1813 (I)-Sunset.

0611 (I)-Dived began submerged approach. Subsequent data
indicated base course 340(T) speed 13 kts. Seas
rough. Able to see target about half the time when running at
55 feet. Target zigging between 070(T) and 330(T). Going in for
bow tube attack. Target then zigged toward giving me a 5 degree
port angle on bow at 3000 yards. Then went across his track for
a stern shot. While crossing picked up his escort on his starboard
bow. Sound then began to pick up this ship. Crossed track.
Observed escort angle on bow 180 range 1800 yards and at

07-17-40 (I)-Began swinging left for a possible bow shot in
case stern torpedoes did not hit.
No explosions.

07-20-00 (I)-Had changed course 70 degrees left. Target range
1520 yards, angle on bow 90° starboard target had
zigged to 070(T).

07-22-40 (I)-Heard tremendous explosion (Torpedo).
07-22-50 (I)-Heard tremendous explosion (Torpedo).
07-22-55 (I)-Heard more tremendous low rumbling explosion (Ship
explosions).
07-23-00 (I)-Heard tremendous explosion (Torpedo).
Sound operator followed torpedoes directly into
targets screws and screws definitely stopped after explosions.
They were NOT heard again. The escort screws were followed and
plainly heard by the other operator through out this action and
subsequent depth charging.

07-23-10 (I)-Could not see target as we were now at 70 feet
(Found out afterwards one poppet valve stuck open
and we took on about 5000 pounds of water forward).
Not knowing what the escort was up to and not able to get up to
see target at

07-23-15 (I)-went to deep submergence and rigged for silent run-
ning. Low muffled explosions and noises could be
heard in the sound gear and through out the ship. They were not
depth charge explosions. Sound operator searched for and did not
hear screws of target. However the escort could be heard very
plainly. I am sure target sank.

07-25-00 (I)-Hap hazzard depth charging began with single charges
at infrequent intervals. Escort never picking us up.
We made a large circle apparently looking for us.

08-36-00 (I)-Depth charge #15.
08-36-30 (I)-Depth charge, a distant pattern of 4 (#16 to 19 inc)
08-37-00 (I)-Depth charge, another pattern of 4 (#20 to 23 inc)
Escort then faded out to the northwest.

1342 (I)-Heard last of 8 distant explosions.
1344 (I)-Surfaced to continue search to northwest and also
hope to intercept south bound convoy of 5 ships
reported by SAWFISH.
1808 (I)-Sunset.

We were apparently near the center of a Low Pressure area with seas
changing continuously and wind shifting around 90 degrees in short
intervals. Usually weather, visibility varying from 500 yards to
10,000 yards.

2326 (I)-S.J. Radar contact (Ship contact #5) Began tracking
to gain position ahead for dawn attack. Base course

0412 (I)-Dived.
0454 (I)-Sighted smoke of our convoy dead ahead.
0459 (I)-Sunrise.
Apparently target changed base course at sunrise to 125(T) as
we were unable to gain position for attack while running at
full speed on normal approach course for one (1) hour. Completely
disgusted with the turn of events but determined the convoy was

B. NARRATIVE (Continued)

not going to get away from me I decided to go after him and at

0638 (I)-Surfaced for "end around" run, tops of convoy were
          plainly in sight from my high lookout platform so
          I hauled out at full speed to a point when the "smokes" were
          inview through my periscope and used this as a guide for the "end
          run".
0831 (I)-Ahead of convoy. Base course now 140(T).
0832 (I)-Dived. (See sketch page for composition and maneuvers
          of convoy and GUAVINA).
0858 (I)-"Smokers" coming over horizon bearing 320(T). The
          formation developed to be three medium cargo ships
          one small freighter, trawler or escort and three other small escorts. The three large ships were in line of bearing. The small
          ship astern of the right hand freighter. Two escorts on bow of
          right hand freighter and one escort astern of left hand freighter.
          Maneuvered to gain position in center front of formation.
          I had only one torpedo aft so my "pre-firing plan" was as follows:
          I might arrive at such a position that I would be able to give
          each big ship two bow torpedoes (we had the speed of 7.5 kts.
          down cold) otherwise three torpedoes each at the two best targets.

0958 (I)-The zig before attack put us dead ahead of the left
          hand ship, range 3000 yards, thus the middle and
          right hand ships were my targets which meant three torpedoes each
          and a possible "set up" for a stern shot (one torpedo) at the
          left hand freighter.

09-58-38 to
09-58-57 (I)-Fired three torpedoes at middle freighter range
          1000 yards, track 50 port, gyro 0° (1 divergent
          spread)with continous periscope check bearing.

09-59-10 to
09-59-30 (I)-Heard 3 tremendous explosions, target engulfed in
          black smoke.

09-59-51 to
10-00-13 (I)-Fired three torpedoes at right hand freighter range
          1400 yards, track 65 port, gyro left 15° (2 divergent spread) with continous periscope check
          bearing.
10-00-15 (I)-Swept horizon for smoking target but could only see
          small amount of smoke. Continued to sweep to right
          and saw left hand ship swing to his right. Thus I could not
          possibly swing fast enough for the stern tube to bear on this
          target, although I had given orders to rudder to begin swing.
          Then swept back to second target and smoke of first target had
          almost cleared. No sign of first target as she had sunk. Saw
          second target. Then began looking for escorts.

B. NARRATIVE (Continued)

10-00-40 (I)-Heard two explosions followed by one tremendous
explosion which violently shock the submarine.
This was NOT a depth charge explosion.
10-02-00 (I)-We then began to dip the periscope and as I could
not see I gave orders to go deep and run silent,
as I still thought I could not bring the stern to bear on the
remaining ship.

1005 (I)-Depth charging began, never too close. Two escorts
milling around apparently looking for us. Could
hear continuous sounds of ship breaking up during this period.
Sound heard screws of one heavy and two light ships going off to
southwest plus screws of the two closer escorts still apparently
looking for us. Thus I was sure two targets had sunk. During
this period communication officer decoded a message from ComSubPac.
about "silent running, cavitation below 250' etc", so put on 80
RPMs and cleared area to northeastward.

1037 (I)-Last of thirteen depth charges. I was clearing the
area to the northeast and the escorts appeared to
go off to the southwest.

1045 (I)-Sound heard nothing.
1109 (I)-Distant explosion.
1115 (I)-Distant explosion.
1117 (I)-Distant explosion.
1230 (I)-At periscope depth, all clear.
1300 (I)-Sighted patrol boat ahead 1000 yards dead in
water. Looked like he was "playing possum".
Went deep again.
1430 (I)-At periscope depth. All clear.
1807 (I)-Sunset.
1830 (I)-Surfaced. I believed the remains of convoy could
easily make port (CHICHI SHIMA RETTO) before I
could again overtake them so did not pursue. Continu-
ed to patrol assigned area.

0505 (I)-Surfaced. Decided on surface patrol today.

1146 (I)-Lookout sighted (Ship contact #7) submarine bearing
030(T) distance 15 miles. Identified as one of ours
and closed him as he was closing us.
1215 (I)-In Latitude 29-16(N) Longitude 142-41(E) close
aboard DRUM. Exchanged "dope" via megaphone.

I decided to scout to the northeast as DRUM was
going back to his area and scout to the West. Took some pictures
of him as he departed.

1808 (I)-Sunset.
1830 (I)-No contact.

May 2, 1944
0408 (I)-Dived.
0449 (I)-Sunrise.
0510 (I)-Surfaced to continue a surface patrol. The entire
day was a continous rainy squally day with visibility
ranging from 200 yards to 15,000 yards.
1803 (I)-Sunset.
1915 (I)-Made S.J. Radar contact on CHICHI JIMA Island bearing
305(T) distance 34,000 yards. Had been able to
catch a few stars at twilight through rifts in clouds so were
once more sure of our position after 36 hours of doubt.

May 3, 1944
0433' (I)-Dived. Intend to spend the day submerged going in
close to CHICHI SHIMA RETTO and look them over
through the periscope.
0451 (I)-Sunrise. The day is overcast but no rain so should
be good for looking over islands. Took some pictures
of radio towers and possible radar screens, on
CHICHI SHIMA Island.

May 4, 1944
0411 (I)-Dived.
0448 (I)-Sunrise.
0655 (I)-Sighted (Ship contact #8) smoke of three ships
proceeding down west side of island chain of CHICHI
SHIMA (We were on east side) Attempted to gain position for
attack but was loosing game with current in an around islands.
Being on eastern side of chain of islands we could not get in a
position to attack.

0730 (I)-Sighted (Plane contact #3) Float type By-plane. He
appeared to be screening the convoy so I gave up
idea to surface for a run in. Never saw ships but could definitely
see plumes of smoke from at least three ship's. The convoy came
from the northward and I believe that at

1000 (I)-They entered CHICHI SHIMA harbor. If that convoy
was going farther south at a laterdate I believe my
position to intercept him is south of HAHA SHIMA so continued
south during day to observe smoke of ship's going south. No
further smoke sighted after time ship's appeared to enter harbor.

1300 (I)-Float Plane seen for last time over island.
1804 (I)-Sunset.
1838 (I)-Surfaced and headed away from islands to send contact
report to ComSubPac.
1853 (I)-Sighted (Ship contact #9) lights of a ship bearing
090(T). First two white lights and as we closed
two red lights. The red lights then definitely took the shape of
red crosses as we drew closer. Continued on our way not closing
hospital ship any more. She appeared to be on a northwesterly
course, passing well clear to eastward of CHICHI SHIMA Island.

2100 to
2145 (I)-Getting message cleared to ComSubPac. of our "day"
contact, hospital ship and our results to date".
2145 (I)-Took course to southwest for a position of possible
contact with convoy in case it moves south. This
is a bright moon light night, no wind and unlimited visibility.
The first day with good weather since being on station.

May 5, 1944
0419 (I)-Dived.
0452 (I)-Sunrise.
0452 (I)-Surfaced. Will surface patrol today to southward
of HAHA SHIMA Island waiting for the convoy. This
is an exceptional day for visibility. The high periscope should
pick them up MILES away.

1400 (I)-Periscope observer sighted (Ship contact #10)
     small trawler bearing 298(T) distance 18,000 yards
on course heading from HAHA SHIMA toward KITA IWO SHIMA. Not a
torpedo target. Let him go by and turned away to remain undetected.
Continued surface patrolling.

     Will run submerged patrol today in close to these
     Islands.
0449 (I)-Sunrise.
0722 (I)-Sighted (Ship contact #11) small trawler. He was on
     a northwesterly course. Sea was glassy calm. He
was definitely not a torpedo target so went down to get clear of
his fishing spot. At one time he seemed to be following us but
then on further thought I believe he was just fishing and was
around looking at his nets. Got clear of his area to the south
and resumed submerged patrol.

2000 (I)-Departed Patrol Area, "14 Afirm" at latitude 26-14(N)
longitude 143-30(E). Set course enroute for
"Special Mission" via prescribed routing. Have on hand 38,000
gallons fuel oil so am proceeding to station for "Spedial Mission"
on one main engine for fuel economy. Will be on station in ample
time with enough fuel for any necessary running.

May 21, 1944
1827(L)-Sunset. Arrived in circle of 60 miles radius of
  Wake Island for "Special Mission". This mission is
  to act as "Life Guard" Ship for an Air strike on
  Wake Island.

May 22, 1944
0440(L)-On "Dawn Position" (Bearing 225(T) distance 30 miles
  from Wake Island.
0926(L)-S.D. Radar (Aircraft contact #15) at 18 miles, "Coming
  in." Not able to sight plane and as "air strike at
  Wake" was NOT in progress, dived.
1001(L)-Surfaced. All clear.
1203(L)-S.D. Radar (Aircraft contact #16) at 10 miles "Coming
  in." Plane not sighted but as bridge was being
  cleared for dive, one lookout caught glimpse of plane and stated
  that it was a big plane with twin tail.
1240(L)-Surfaced (Lat.18-15(N) Long.166-04(E). Sighted B-24
  bearing 010(T) distance 12 miles. Exchanged recog-
  nition signals. He then turned away toward Wake
  Island.

May 23, 1944
  No Remarks.

May 24, 1944
0515(L)-Sighted many friendly planes (Hell Cats and Hell
  Divers) going in direction of Wake Island for First
  Attack.
0518(L)-Sunrise. Closing in toward Wake Island from my
  position on 30 mile circle.
0649(L)-Two (2) Fighters (F6F) reported overhead as air
  escorts. Throughout the day always two (2) and a
  majority of the time four (4) fighter were maintaining a very
  efficient air cover over the GUAVINA. While cruising around on
  the surface, in the very sight of Wake Island, it was a good
  feeling to have the fighters up there to take care of any possible
  Jay plane activity.
0702(L)-Second wave of many friendly planes sighted and
  proceeded to Wake for Second Attack.
0947(L)-Third wave of many friendly planes sighted and pro-
  ceeded to Wake for Third Attack.
0955(L)-My position now is five (5) miles, bearing 225(T)
  from Wake Island. Island is very clear from the
  bridge and an excellent view through periscope. Cruised back and
  forth along island throughout the remainder of the day for a
  "ring side" view of the various attacks. All planes could be seen
  plainly throughout their "dives" and "pull out" and it was always
  a relief to see each one "pull clear."

-16-

— page 24 —
B. NARRATIVE (Continued)

1153(L)-Sighted a B-24 over Wake Island. Air escort also
sighted and did a good job of "running him clear" of
us.
1235(L)-Fourth wave of many friendly planes sighted and pro-
ceeding to Wake for Fourth Attack.
1443(L)-Fifth wave (two(?)) separate flights of many planes
each) sighted and proceeded to Wake for Fifth Attack.
For this attack we were now 9,000 yards off Wake Island and had
an excellent view of the attack. Throughout the day we obtained
"motion pictures" of the attacks, which pictures would have been
much better had we a telescopic lens on the camera.

Throughout the day we had not seen a plane crash and as our air
cover did not "Zoom us" to point out any I concluded there were
no losses. Also I had not received any "S.O.S." call over the
"VOX CALL".

May 26, 1944
1825(L)-Sunset. Departed area. Proceeding in accordance
with instructions to MAJURO via prescribed routing.

Sent message to ComTask Group 17.6 information ComSubPac. regarding
rendezvous with MAJURO escort.

Receiver conformation from ComSubPac. and Notification that
HASTINGS (DE 19) would be escort.

May 27, 1944
1340(L)-Sighted HASTINGS (DE 1019) in Lat. 10-12(N) Long.
170-38(E) bearing 210°(T) distance 15 miles. Man-
euvered to receive mailing tube then set course to proceed in
company with him to MAJURO.

May 28, 1944
0500(L)-Arrived off MAJURO.
0603(L)-Moored alongside SPERRY.

C. WEATHER.
Weather encountered agreed with Available information namely:
easterly winds with occasional calms, visibility good to very
good, infrequent gales with shifting winds.

D. TIDAL INFORMATION.
In the vicinity of the BONIN Islands, the currents out side
of the hundred (100) fathom curve were found to vary but were
of little consequence.

E. NAVIGATIONAL AIDS.
The island of "SOFU GAN" (Lots Wife) Latitude 29-49(N)
Longitude 140-21(E) is very conspicuous during day light and
at night and is a good land mark for a "Land Fall" for sub-
marines passing this area. I believe that Japanese shipping
might n ow be using it for a "Land Fall" for their north and
south traffic. The island was also used to great advantage
in tuning the S.J. Radar.

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS.

During the attack on April 25, 1944, the escort vessel, which
appeared to be a small version of one of our D.E. escorts, was
never able to locate me. I had gone to deep submergence and
headed into the wake of the sinking target. I kept my propeller
turns fairly constant at a slow speed which gave the least shaft
noise (between 65 & 75 RPMs) and of course ran silent. I had to
keep the rudder amidships as it did a lot of growling in hand
power. During the noise of the depth charges I would use the
rudder as desired.
During the attack on April 26, 1944 two small escorts were on
my trail but neither appeared to find me. Again I went deep and
headed for the wake of my sinking target with fairly constant
propeller turns. The escorts seem to stay about more, then in
order to prevent being the rudder I steered the ship, after a
fashion, by varying the speeds of the propellers and was able to
maneuver the ship clear of the escorts.
On both days my deep submergence was well below 300 feet. The
depth charges seemed to be small ones and NOT set deep.

K. MAJOR DEFECTS AND DAMAGE.

Defect #1. I believe a comment on "shaft noise" is in order
at this point. An unsatisfactory acceptance trial item for the
GUDINA was "shaft noise" at slow speed. A brief history is as
follows: An experimental combination wood and babbit stern tube
bearing was originally installed which gave a high pitch hum and
low pitch growl at slow speeds (around 40 to 70 RPMs). This was
removed by the building contractor (Manitowoc Shipbuilding Co.)
and a standard wood stern tube bearing installed. The high pitch
hum was eliminated but the low pitch growl remained but to a lesser
degree. The ship left Manitowoc and proceeded to Panama via
New Orleans, La. In New Orleans a new port propeller was install-
ed to replace one bent in the ice at Manitowoc. While in New
Orleans a fuel barge was set up on my starboard propeller giving
it a bad nick. This propeller was repaired before leaving New
Orleans, La. The low pitch growl was gradually working its way
out and sound tests at Panama still indicated a pronounced noise.
During voyage from Panama to Pearl Harbor I was conscious of
a ship vibration which I believe was caused by unbalanced
propeller.
Upon arrival Pearl another sound test still indicated shaft
noise at low speed but to a lesser degree than in Panama. Two
new balanced (Static and dynamic) propellers were installed and
two weeks of operations around Pearl Harbor followed. With the
balanced propellers the ship vibrations were definitely eliminated,
the difference being very pronounced because of the lack of vi-
bration.
Prior departure on this patrol another sound test at Pearl
Harbor indicated the shaft noise was about gone with slow speed
steady running, but still existed to a small degree when
propellers come to stop.
Thus in conclusion I say that the unsatisfactory shaft noise
is about completely eliminated and by a common sense operation
of propeller speed I can run almost silent for "silent running".

Defect #2. During "silent running" in "hand steering" the
rudder operates with a tremendous growl. The noise can be heard
through out the ship whenever the rudder is moved. I have no
theory to advance at this writing but a thorough investigation
will be made during the coming refit. We might find it is only
a greasing problem.

L. RADIO

In the vicinity of the BONIN Islands radio reception could
be classed as normal with the usual bad effects at dawn (Between
1900 zebra and 2100 zebra). "Ship to Shore" transmission was
accomplished more efficiently via Australian Stations than via
Radio Honolulu. On our first transmission in the area Radio
Honolulu (N.P.M.) directed us to send "VS" after the "call up"
where upon the Australian Station (VHC) came right in with the
appropriate "QRV" signal, telling us he would receive and relay
the message. Our second message was promptly received by the
Australian Station (VHC) for relay.
A casual observation would indicate that the Australian
Stations are a little more "on the ball".

M. RADAR.

Maximum S.D. Radar ranges were forty-five (45) miles for land
targets and twenty eight (28) miles for aircraft. Intermittent
radar interference was encountered up to two hundred (200) miles
from CHICHI SHIMA Island (BONIN Group) with strongest indications
at seventy (70) miles and weaker indications when closer to the
islands. This probably indicates a high power land based air-
craft search radar. On one day a close reconnaissance was made
of CHICHI SHIMA Island and towers were observed on hill tops
which could have been Radar Towers. Photos were taken of these
towers.

On the day we contacted the USS SKATE we began having inter-
ference on the S.D. Radar which interference pattern indicated
another S.D. Radar in operation. This put us on the alert that
another one of our submarines could possibly be in our vicinity.
About one (1) hour later we contacted the SKATE.

S.J. Radar conditions were average. The Magnetron Tube had to
be renewed before arriving in area and some difficulty was ex-
perienced in tuning the equipment. Contacting the island of
"SOFU GAN" greatly aided this tuning. A check tuning was also
made on day we contacted SKATE. An "echo box" would be invalu-
able for such work.

N. SOUND GEAR AND SOUND CONDITIONS.

Sound conditions are classed from poor to fair with maximum
listening ranges of 6000 yards off CHICHI SHIMA Island (BONIN
Group). Resorts encountered appeared not to use "pinging" and
based on the fact that we apparently were not located on either
attack, their listening equipment is none to efficient.

O. DENSITY LAYERS.

No density layers were encountered off the northern end of
the BONIN Islands. On a line between HAHA SHIMA AND KITA IWO
SHIMA we encountered a sharp negative gradient varying between
2° to 8° from the surface to one hundred sixty (160) feet, then
isothermal down to three hundred (300) feet. Bathythermograph
cards are forwarded under seperate cover.

P. FOOD, HEALTH AND HABITABILITY.

FOOD: Fooding is classed as very good. A fair supply of
frozen foods were obtained prior departure on patrol which were
excellent. The more the variety and the greater the supply of
this type food the better. We improvised a "SPUD" locker in
our "CREWS MESS" hatch for extra stowage and we carried enough
potatoes to last the whole patrol.

HEALTH: The health of all hands was very good. Daylight
surface patrolling gave us all a lot of sunshine, vitamine pills
were issued throughout patrol and all hands were able to get
enough good rest between watches. A few "cut fingers" on the
mess cooks were our greatest injuries.

HABITABILITY: was excellent, we were, of course, in moderate
climate weather the whole patrol plus the fact that the Air
Conditioning functioned well which made the living conditions
very good.

Q. PERSONNEL.

Personnel performance was very good. After the Gun Action
early in the patrol (April 22, 1944) the whole crew seemed to
settle down to the business of doing his job to "fight this war".
I feel I have a well trained, keen working organization with every-
one doing his job. Their reaction under depth charge attack was
very good.
Throughout the patrol the officers have worked hard at gett-
ing unqualified men qualified and with good results.
I carried nine (9) officers (including C.O.) on this patrol
and found it very good in that it gave us an extra junior watch
officer, another "decoder" and gave all the unqualified officers
more chance to "learn the boat". I believe I could carry one
more unqualified officer with no strain.

(3) The Commander-in-Chief, U. S. Pacific Fleet.

Subject: U.S.S. GUAVINA - Report of War Patrol No. One.

1. The First War Patrol for the GUAVINA extended
from 6 April to 28 May 1944, with about 27 days spent in the
BONIN area and 4 days on lifeguard at WAKE.

2. Area coverage was good; about 40% of the daylight
patrol was spent on the surface; enemy air activity was lighter
than expected.

3. Attacks:
No. 1 (19 April). This was a snap night surface
attack in the initial encounter of this new submarine. Three
torpedoes missed due to (a) target being of trawler size much
smaller than estimated on initial sighting three minutes before
firing, and (b) torpedoes set too deep.
No. 2 (25 April). Large single AK with one escort.
Four stern tubes missed the freighter at close range in a day
periscope attack. Misses were due to a poor setup - a combina-
tion of large gyro and track angles, inaccurate range and 2-knot
speed error. The Commanding Officer then swung for a bow shot
and fired 4 tubes on about 145° tracks which made 3 hits. This
shot was made possible by a 'zig toward' after firing the stern
tubes. Recorded fire control data for this hurried bow tube
salvo was scanty and courses and track angle cannot be made to
check. It is believed that the evidence justifies crediting this
ship as sunk.
No. 3 (26 April). A skillful day periscope mul-
tiple attack on the two largest freighters in a seven ship convoy
(including 3 or 4 escorts). Six bow tubes were equally divided
between the two targets. Three hits definitely sank the first
(largest) ship. Two hits and heavy explosions indicate that the
second ship also sank. Depth charging was never close.

A. PROLOGUE.
The CUAVINA finished her first War Patrol on May 28, 1944
when she arrived at Majuro Atoll, Marshall Islands. Refit was
conducted alongside the SPERRY under ComSubRon. 101. On May
29, 1944 the ship was docked in ARD 13. This was primarily a
practice docking to give experience to the ARD 13. No extensive
docking repairs were required by CUAVINA and she was undocked same
day. The rudder bearing was given an extensive greasing which
has eliminated the noisy performance of the rudder during silent
running which was reported in the first patrol report. During
refit, #1 main engine was overhauled and main bearings in all
main engines were inspected and renewed as necessary. The rest
of the refit consisted of normal tender refit work. On 14, 16 and
17 June 1944 Sea trials and training runs were conducted. Six Zed,
five radar, one radar tracking and three Battle Surface runs were
made. No torpedoes were fired.

P. PREVIEW TO NARRATIVE.

June 27 to July 8 on patrol in the areas to the West and
North of PALAU.
On July 3, 1944, spotted convoy of one merchantman with
foru escorts enroute PALAU. Before dawn on July 4, 1944 sank
the merchantman with three (3) hits out of spread of four (4)
steam torpedoes fired. The A.K. was similiar to ADEN MARU class
(GROSS TONS 5824 T). Received 18 close, accurate, but to shallow
depth charges. Received no damage.
No other enemy ship contacts.
July 9 to July 21, 1944. Had additional duties as "Life Guard"
ship in area "YAP ULITTI", with instructions to guard two approp-
riate aircraft frequencies from 1030(I) to 1200(I) daily and remain
on surface if possible during air strikes.
July 11 rescued four(4) "aviators" from liberator which crash-
ed July 10. No more survivors from this crash.
July 19-20, rescued eight (8) "Aviators" from liberators which
crashed July 19. No more survivors from this crash.
Aviators were returned to Army Thirteenth Air Force Headquarters
at SEVADLER, MANUS ISLAND. A separate report, giving details of
rescue, has been forwarded to ComSubPac.

June 25, 1944 Enroute Area.
1035(K) In Lat 05-27(N) Long 145-45(E), sighted (Aircraft
Contact #2) at range of 20 miles. It was a PRY
and about 1 degree off horizon and never picked up on S.D.
Radar. We circled around to the north and then went off
to the southeast never coming in closer than 20 miles. Con-
tinued on surface to area.

June 26, 1944 Enroute Area.
0855(I) In Lat 06-12(N) Long 140-19(E), S.D. Radar Contact
(Aircraft Contact #3). This developed into three
(3) prominent "Pips" between 24 and 32 miles. Closed
into range of 16 miles then opened out again. Planes never
sighted. Judging from size of "Pip" believe it was a flight
of our planes enroute to bomb YAP or vicinity. Continued
on surface to area.

0840(I) Aircraft Contact #8. This plane was a "RUFE".
Throughout the day this plane or his relief appeared
to be station patrolling in the area in which we were sub-
merged. I believe that he never sighted us, but nevertheless
his persistence in the area kept us submerged.
1630(I) This was the last time the "RUFE" was sighted
through the periscope.

1841(I) Surfaced. Continued on to our proper area for
rotation in the "Speedway". Fortunately there was no one
scheduled to be in the two areas I had to pass through in
order to get to my own area.
2140(I) Aircraft Contact #9. This plane was never sighted.
Its range decreased to about 20 miles at minimum
and then faded out again at about 30 miles. Believe it to
be a Jap plane either entering or leaving PALAU. Interference
on S.D. screen made me believe he carried RADAR.

1310(I) A large gust of smoke was sighted in the direction
           of the northern part of the island. Part of this
           appeared to be smoke similiar to that I had seen when "Life
           Guardine" aake Island on First Patrol. Part of the smoke
           could have been a ship inside the reef. Its persistence
           and bearing did not change so finally concluded
           it could have been some of our planes on bombing PALAU and
           subsequent activity of enemy planes indicated there
           probably up and out doing their best. Rain and clouds over
           the island during the day some what obscured my view but
           towards the later afternoon atmosphere became clear so that
           the islands could be seen plainly.

           seemed to be flying around us during evening and
           would make frequent "SORTIES" over and around us. Believe
           this is what lookout saw. The dive had been "night"

1324(I) Sighted mast of merchant ship. Maneuvered for an
          attack position. At first observation, angle on
          bow was 60°port, range 20,000 yards on course 060°(T)
          which developed to be his extreme left hand zig. The
          formation turned out to be a merchant man with four escorts,
          (two CHIDORI and two AM-13 class), two escorts were screen-
          ing on either bow well ahead and two escorts were patrolling
          one on each quarter well out and astern with a float type
          zero hovering over formation.
1516(I) With running at fast speeds on normal approach
          courses for about 1 hour and 42 minutes I was un-
          able to get into attack position, the closest range being
          5000 yards on the port quarter of the port stern escort.
          The base course proved to be 100°(T), speed 9½ knots.
          Decided to trail behind submerged until sunset in prepara-
          tion for a night "end around."
1833(I) Sunset. Surfaced. Smoke of convoy plainly in sight.
          His base course was heading him for PALAU with
          about 140 miles to run at 9½ knots. Began "end around" port
          side of convoy, with moon 90° full and sea glassy calm.
1910(I) Cleared "Contact Message" to ComSubPac. on sub
          frequency. It was not quite dark so purposely held
          off sending "Contact" on "Area" frequency first. Within
          5 minutes of my transmission, a rebroadcast was "on the air"
          from F.P.M., so did not transmit on "Area Frequency".

2228(I) Sighted two "Spitkits" sharp on port bow so
        maneuvered to avoid possible detection. They
        might have been pickets or just fishing but did not stop
        to investigate as there was "bigger game" in sight.

July 4, 1944
0015(I) Began receiving interference similar to our S.J.
        Radar.
0040(I) In convoy estimated 0200 Position. Sighted Sub-
        marine, (Ship Contact #3), about 2000 yards.
        Believed this to be FINBACK, put him astern and headed
        further east along convoy's track.
0240(I) In position ahead of convoy as checked by the
        "escorts pinging".
0245(I) Sighted smoke of convoy with Radar range 24,000.
        The moon was behind convoy with about one (1)
        hour before setting.
0254(I) Confident I had convoy course and speed and not
        wanting to be sighted in the moonlight night dived
        ahead of convoy.

03-48-30 to
03-48-54(I) Fired four bow (Mk.XIV) torpedoes. At the merchant-
        man who was still "Foxed in" by his four escorts.
03-49-54(I) Heard first torpedo explode and heavy screws stopp-
        ed. This was followed by two more torpedo hits
        and a tremendous explosion almost simultaneous with third
        torpedo hit. The after starboard escort was giving me a
        zero angle on bow and was too close for me to shoot at him
        so went deep into wake of my target.
0354(I) First of 18 close, accurate but too shallow depth
        charges. During depth charging the target could
        be heard breaking up as if he were right alongside. There
        was no doubt in my mind that the target had received 3 hits
        and sunk.
0400(I) Last of the 18 charges. I had gone to 300 feet
        and went ahead 90 RPM and began clearing area to
        the westward of TAIAN. The four escorts "milled around",
        in vicinity of attack, pinging vigorously but never making
        contact with me.
0442(I) Sound heard one distant explosion.
0545(I) Sunrise.
0600(I) With pinging well astern began coming to periscope
        depth.
0638(I) Sighted a "MAVIS", (Aircraft Contact #19), at 15
        miles in direction of attack.
0639(I) Sighted a "RUFE", (Aircraft Contact #20), Close
        aboard.
0640(I) First of 8 aireal bombs. Not too close. Started
        deep.

0643(I) Last of 8 bombs. None close. Pinging from
         direction of PALAU gradually "died out" through
         out morning as I continued westward. Continued normal
         submerged periscope patrol remainder of the day. Throughout
         forenoon we could hear the distant pinging of the escorts
         who were apparently looking for us.
1830(I) Sunset.
1851(I) Surfaced. All clear.
2210(I) S.J. Radar began receiving strong interference
         which resembled our own S.J. type. As we were
         still in the area (10 FAKER) assigned to FINBACK. I believed
         it a strong possibility that we could be near him. It was
         a rainy squally night and the interference appeared to come
         from the direction of a particularly large rain squal.
         Certain it must be one of our subs and not wishing to en-
         counter him in a rain squal, I did not attempt to investigate.
         Continued on to my own area.

July 5, 1944 In patrol area 10 BAKER.
0531(I) Dived.
0600(I) Sunrise.
0650(I) Began hearing distant "pinging". Change of true
         bearing indicated it to be to eastward of us in
         direction of PALAU and appeared to be searching. Guess we
         made them mad yesterday and they are determined to "hunt
         out" the American submarines.
0715(I) No more "pinging".
1330(I) Began hearing very characteristic propeller noises
         which could have been fish as nothing was visable
         through periscope. However there is a strong possibility
         it could have been another submarine. Continued in direct-
         ion away from "screws" which soon faded out. One thing is
         certain there is a definate increase of anti-submarine
         activity in the area.
1838(I) Sunset.
1850(I) Surfaced.

1020(I) Aircraft Contact #26, with S.D. at 35 miles.
1111(I) Aircraft Contact #27, with S.D. at 16 miles. This
Contact showed up at that range and had not been
"tracked in" with the other "Pips". It was a smaller "Pip"
indicating a small plane. The sky was cloudy and the plane
was not sighted. It came in rapidly to 14 miles and believing
it could be a Jap fighter did not care to let it get closer.
1112(I) Dived.
1157(I) Surfaced.
1208(I) Received message over "Life Guard" frequency that
plane was down, bearing 285° distance 70 to 80

full speed toward this point. Several repeat messages en-
route verified the location.
1337(I) Aircraft Contact #28, S.D. Radar at 14 miles.
1338(I) Sighted airplane which was a JAP FIGHTER. He was
dead ahead (In other words in the direction of our
"downed aviators"). He appeared to be returning toward YAP,
and at 12 miles turned toward us and began closing range
rapidly.
1338(I) Dived.
1416(I) Surfaced. Continued at full speed to point of

0430(I) Received message from ComSubPac. that position of
"Downed Aviators" was given as Lat. 8-40(N) Long.
138-56(E). This position is 18 miles bearing 312 from
position I originally received and was included in
area we were searching.

0531(I) Sunrise.
0630(I) In position sent out by ComSubPac. NO AVIATORS.
           Continued systematic search of area.
0911(I) Aircraft Contact #29, sighted two Liberators at
           18 miles angle elevation 1 degree. They closed in
           on us to about 4 miles, then went out. They are searching
           area for the "Downed Aviators".
1005(I) Aircraft Contact #30, sighted a "RUFF" at 18 miles.
           He did not sight us.
1054(I) Aircraft Contact #31, S.D. Radar at 45 miles. These
           are our liberators on daily bombing mission of YAP.
1214(I) Last "Tip" disappeared from Radar Screen. Liberators
           headed south for base. During day investigated every
           piece of floating object sighted during systematic search of
           area. The day was clear and water very calm so that sighting
           objects in the water at 4 and 5 miles was not difficult. It
           seems incredible the number of logs and oil drums floating
           about. At one time recovered a "life ring" which had apparent-
           ly been floating for days and it had no markings. At another
           time sighted and hauled aboard a small native dugout canoe
           with no evidence of life.
1314(I) Sighted "another floating" object. As we closed
           this another black shiney object appeared. Closed
           this and took on board the tire and attached landing gear for
           a large plane. We were in area where plane crashed. Other
           yellow objects began to show up around us. Then on the horizon
           a possible raft, yes it was a raft. Men were waving their
           arms.
1420(I) In Lat. 8-43(N) Long. 138-39(E), took on board three
           men from rubber boat. Flooded down so we could
           "easy" them aboard as they were injured. This group informed
           me there was one more survivor from the B-24, and that he had
           drifted westward. He was about 5 miles west of first group.
           This was the Co-Pilot and he was not injured. He scrambled
           aboard with ease. My Pharmacist's Mate supervised getting
           the injured below and began treatment. The Co-Pilot assured
           me these were the only survivors.
           I continued to scour the area and take on board all
           the floating gear in the area as I wanted to leave no "marker
           buoys". This proved to be all the "emergency equipment"
           such as "jungle kit", sun distiller, medical kit, empty oxygen
           bottles and identification kit. There was also a floating
           rubber covered gasoline tank. It was full of gasoline. We
           chopped holes in this and let it sink. By sunset we had
           removed all the floating evidence from the water.
           By this time my Pharmacist's Mate reported he had
           the situation well in hand, he had dressed all the wounds,
           administered a little brandy and had in general gotten the
           four pretty well settled down. He stated the injuries were
           minor and that he could handle the job.

1023(I) Aircraft Contact #35, S.D. Radar at 55 miles. These
are our Liberators coming in over YAP.
1156(I) Observed a tremendous water spout and smoke in
direction of returning planes from bombing mission,
well over horizon. Believing it to be one of our planes
crashed began heading for it. Later observed a Liberator
circling the position where we had seen smoke.
1220(I) Received message that one of our planes was down,
and that 9 parachutes were observed to open of men
who bailed out. Position given was within 15 miles of where
we were heading. We closed the area and began a systematic
search for the downed aviators. As it later developed the
PILOT was the only one who was able to get near one of the
many rubber life rafts which were found in the area. This
day was choppy and windy so that it was extremely difficult
to "SPOT" the men floating in the water in their life jackets
as just there heads would be out of water. However the seas
were becoming more calm so that our "SPOTTING" became better
and better.
1449(I) First survivor (PILOT) aboard. He had a rubber raft.
1510(I) Second survivor (BOMBARDIER) aboard.
1515(I) Third survivor (GUNNER) aboard.
1809(I) Sunset.
1823(I) Fourth survivor (GUNNER) aboard.
1827(I) Fifth survivor (ENGINEER) aboard.
1950(I) Sixth survivor (NAVIGATOR) aboard. It was now pitch
dark and we could hear him shouting. Trained search
light in direction of noise and found him about 100 yards off
the port beam. He stated he was very tired and could not swim
further. If I maneuvered I might loose him in the seas. The
Torpedo Officer, Lieutenant J. P. Neenan, USN (A strong swimmer)
volunteered to go out after him, so with a line around himself,
Lieut. Neenan swam out to the man and brought him back to the
ship. The man was so weak he had to be hauled on board.
2000(I) Received message from ComSubPac. to discontinue Life
Guard duty and began normal Rotation in Speedway.

and would continue job until further orders.
During night continued a slow cruising throughout area,
using megaphone to call out to see if we could get and response.

0500(I) Received message from ComSubPac. to continue search
one or more daylight periods as I saw necessary.
0530(I) Seventh Survivor (Asst. RADIO OPERATOR) aboard. As
we were passing this man abeam he used his packet of
"Green Sea Dye" which gave a good marker that the lookout
spotted.

We was well out from the ship and if the man had not used the
dive we would have passed beyond him that sweep.
1052(I) Aircraft Contact #36, sighted 2 Liberators at 9 miles,
looks like they are searching too.
1715(I) Ninth survivor (RADIO OPERATOR) aboard.
1735(I) Took on board a floating opened parachute. This was
near to the 8th survivor. This parachute had a small
Pilot chute and the 8th survivor assures us that when he bailed
out his pilot chute pulled off his main chute during descent.
Recover no man around in water.
1809(I) Sunset.
2000(I) Sent message to ComSubPac that one of men from the
rescue on 14 July was developing complications in
a leg wound which needed Surgeons care and we could handle
danger for 6 days.

July 21, 1944
In Patrol Area 10 EASY, Looking for downed aviators.
There were two more (Total 10) in the plane crew.
0400(I) Received message from ComSubPac to spend one more
daylight period in search, then proceed to STEADLER.
Sunrise.
0535(I) Recovered an Aviators Life Jacket. All the men we
0640(I) brought on board were still wearing theirs when
rescued. We were in the immediate vicinity of where we had
rescued the 7th survivor and the parachute the night before.
This jacket had black burn smudges on it, neither CO2 charges
had been fired, although one CO2 holder appeared to be partially
torn loose as if some one had attempted to pull the cord but had
pulled sideways instead. The gunners had been fighting fire
in the turret before bailing out. One gunner was still missing.
On the other hand the pilot informed me all planes were suppos-
ed to carry one extra jacket so that there is a 50-50 chance
there is one extra life jacket.
1037(I) Aircraft Contact #37, S.D. Radar at 55 miles. Our
Liberators going in for bombing mission of YAP.
Continued search throughout day for missing Co-Pilot and Gunner.
The sea was very calm and visibility was excellent so that
if the men had been there we would have seen them. During
the entire rescue period we found much evidence of the plane
crash which we removed. We took on board a total of seven (7)
rubber life rafts. The one the pilot had was partially inflated
and fairly serviceable. One near the plane slick was fully in-
flated but bottom split. One more, nowhere near any survivors,
was partially inflated. Having no sea anchor it had been
blown by the wind away from wreck. Four (4) were not inflated,
either "blown out" or broken and just awash, not near any
survivors.

TORPEDO ATTACK REPORT FORM.

USS GUAVINA(SS362) Torpedo Attack No. 1. Patrol No. TWO.
Time: 03-48-30(I) July 4, 1944 Lat. 07-33-30 N. Long. 133-45 E.

TARGET DATA = DAMAGE INFLICTED.
Discription: One (1) A.K. and four (4) destroyers (2-CHIDORI -
  - AM-13) in convoy covered by float zero. Convoy con-
  - tact at 1318(I) on July 3, 1944 in Lat. 8-04 N. Long.
  - 131-37 E. and viewed at closest range of 5,000 yds.
  - While patrolling on surface we obtained on S.D.Radar
  - contact of the air screen at 16 miles. After diving
  - obtained sound contact on escort pinging which
  - affected the complete contact.
  - After dark made end around run and made contact
  - again with this convoy and at 03-48-30(I) to
  - 03-48-54(I) fired four (4) Mark XIV torpedoes at the
  - A.K.
  - This A.K., as viewed on afternoon of July 3, was
  - "ESTIMATED CERTAIN(TC)" to be similiar to the ADEN
  - Maru Class as shown in ONI 208J revised, on page
  - 189 (GROSS 5824-901)

Damage: A.K. listed above - SUNK.
  - Heard three (3) torpedo hits, screws stopped and
  - were never heard again, a tremendous explosion
  - immediately following third hit and subsequently
  - loud characteristic breaking up noises was heard
  - through out the submarine, these noises being so
  - pronounced that there is no doubt in my mind that
  - target sunk.

Target Draft: 27 Feet Course: 140° Speed: 10 Range 2030yds.at fir/ing

OUR OWN SHIP DATA.

Speed: 2.5 kts. Course: 025°(T) Depth: 63 ft.Angle:0° at firing.

FIRE CONTROL AND TORPEDO DATA.

This attack followed a night end around run. The
moon was about 90% full and had about an hour before
setting. I had thought the moon would aid in seeing
target but shortly before firing the sky clouded
over so that the night visibility through the peris-
cope was only fair. I was able to obtain a position
ahead of convoy away from moon. The A.K. smoked
a great deal which made possible getting bearings at
ranges outside 10,000 yards. I was heading toward
convoy, one

small destroyer on either bow of A.K., angle on
bow of A.K. 10° starboard. Shortly before firing
the convoy zigged to its left giving me a view of
angle on bow of about 45 starboard. I then came
right and fired when having a zero gyro angle with
a track angle of 65 starboard, using a divergent
spread of (4R 1R 1L 4L), with a continuous periscope
check bearings during firing. The first torpedo
missed ahead and the last three hit. By plot #4
torpedo would have missed astern but after the target
was hit by #2 and #3 torpedoes, I believe she was
slowed enough for #4 torpedo to hit astern.

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS.

The contact on July 3rd was a merchantman escorted by four
(4) escorts. The escorts were doing the usual "pinging" and in
the locality to the west of PALAU this "pinging" could be heard
for at least 20 miles. The convoy also had a single float "zero"
covering. This plane had been detected by S.D. Radar and caused
us to dive, whereupon soon thereafter sound heard the "pinging".
There followed a night end around run and having gotten in posit-
ion ahead of convoy it was the long distance "pinging" which first
assured us we were in good position ahead for attack. The four
(4) escorts (Two(2) Chidori and two(2) AM-13 Class) formed a
square around the target boxing him in very well. After the tor-
pedo attack one rear escort was able to drop 18 close, accurate
depth charges. I had started deep and was below 250 feet when
the first depth charge went off. The charges all went off direct-
ly overhead. I had fired with bow tubes, zero gyro, so I con-
tinued course directly into wake of target as I went deep, using
90 RPM below 250 feet with good results. We had gotten close to
the target and we could plainly hear it breaking up. It seemed
as if it were falling all around us. This breaking up could be
heard, plainly, through the hull. The remainder of that day and
the day following the "area of my attack" seemed alive with "ping-
ing" ships apparently out looking for SURVIVORS. The following
day my operation order cleared me from that area.

K. MAJOR DEFECTS AND DAMAGE.

The noisy rudder which was reported as "A Defect" in first
patrol report, was thoroughly inspected and greased during the
last refit. It operation now is entirely satisfactory.

The S.J. Radar failed completely about the middle of this
patrol. A complete check will be made and cause remedied during
refit.

I. RADIO.

In the P/L/A/U area, radio reception was good between the
hours of 2000 to 1400 CCT. During the remaining hours reception
dropped to strength two, making reception possible but extremely
difficult. Ship to shore transmission on the 4235 Kc. series
with radio Honolulu was possible only up to 2300, zone (-9). After
this hour it was impossible to hear Honolulu, and all ship to shore
traffic was cleared through AUSTRALIAN stations with good results.
There was only a slightly noticeable increase in the reception of
Haiku Fox on 17,370 Kc. During daylight hours far better results
were obtained using 14,300 Kc.

Due to instances having been reported of enemy radio stations
answering ships on the "ship to shore" frequency, it is suggested
that shore stations authenticate their initial transmission to a
ship calling on the "ship to shore" frequency when telling him to
"go ahead". With this authentication, the ship will know that the
station answering his call is friendly and will know whether to
continue with the broadcast.

M. RADAR.

On July 4 at 2210 a type of Radar interference was noted on
the S.J. Radar. This band was about 10 degrees wide and excellent
bearings could be taken on the source. The appearance was "rail-
line" on the A scope and "speckled" on the P.P.I. I believed
this to be another American Submarine(The FINBACK).

The performance of the S.J.-1 Radar was limited due to a
series of major breakdowns. The performance of the S.D.-4 Radar
was excellent. Formations of heavy bombers were picked up at
ranges from 55 to 70 miles. Single plane contacts were picked up
from 15 to 32 miles. Aircraft radar interference was noted
approximately 15 minutes before friendly bombers and patrol planes
were contacted.

M. RADAR (Continued).

During this patrol run the following types of interference
on the S.D. Radar were encountered:

TYPE ONE.

Pulses of closely spaced railings rise from the sweep. These
look somewhat like patches of grass but seem to be rounded on top
indicating possible modulation. The amplitude varies but is all
visible on the screen. In most cases it sweeps across the screen
from right to left in about three second sweeps. This type of
interference was very common around the Jap held islands of PALAU
and YAP. Presumed to be Japanese Land Based Radar.

TYPE TWO.

Very closely spaced railings appear suddenly and extend from
the sweep over the top of the scope. These railings do not move
across the sweep but remain relatively steady until they disappear
suddenly. This interference comes and goes at irregular intervals.
Most of the interference of this type occurred at or near the time
that Liberator Bombers were near us enroute to or returning from
a bombing raid.

TYPE THREE.

The sweep becomes very distorted. The sweep appears in
various shapes, many of which resemble sine waves. Most of this
type of distortion occurred when some nearby plane was using
voice modulation on radio transmission. This fact was checked
with received voice messages in the radio room.

TYPE FOUR.

A single railing rises from the sweep and moves across the
screen usually from right to left. This is sometimes seen when
our own S.J. Radar is operating. When this type of interference
is seen and our S.J. is not operating it is probably due to an
S.J. set on some other American Submarine.

N. SOUND GEAR AND CONDITIONS.

    Sound conditions ranged from fair to good. Pinging of
    escorts was heard at approximately twenty miles. Screws of
    escorts could be heard at 9,000 yards. No ping ranges were taken.

O. DENSITY LAYERS.

    On July 4th a layer was noted at Lat. 7-47 N. Long. 133-18 E.
    There was a slight negative gradient from the surface down to 240
    feet. At 240' the negative gradient increased sharply. To avoid
    detection this layer was used. Running below it at standard speed
    the submarine was never detected by the four searching escorts.
    On all other occasions in the PALAU area an isothermal layer was
    noted between the surface and 100 feet.

P. HEALTH, FOOD, AND HABITABILITY.

    The first two patrols of the GU VINA have been in areas
    with relatively good weather and a major portion of the patrolling
    time was spent on the surface so that the crew has been able to
    be in the sunlight a great deal. This, together with a well
    organized Commissary Department that is able to prepare well
    balanced meals, in adequate quantity, has kept the crew in good
    health. The air conditioning continues to function properly and
    the habitability is entirely satisfactory.

Q. PERSONNEL.

    During the torpedo attack on July 4 and the subsequent
    rescue of twelve (12) "Army Aviators", on July 14, 19 and 20,
    the courage and enthusiasm of the officers and crew was of the
    highest order.

FIRST ENDORSEMENT to
CO GUAVINA ltr. SS362
A16, Ser. 017 of
July 31, 1944.

From: The Commander Submarine Division 182.
To: The Commander-in-Chief, U.S. Fleet.
Via: The Commander Task Force SEVENTY-TWO.

Subject: U.S.S. GUAVINA (SS362) Second War Patrol - Comments
         on.

1. During the second patrol of the GUAVINA, twelve days
were spent in the PALAU area during which an enemy merchantman
protected by four escorts was successfully attacked, three hits
being obtained out of a four torpedo salvo. This proved to be the
only contact of the patrol. Thirteen days were spent on lifeguard
duty off YAP during which period twelve U.S. Army aviators were
rescued.

2. The one attack occurred in the early morning of 4 July
1944. This was conducted by periscope in bright moonlight follow-
ing a well executed end-around run. Torpedo run was 2030 yards,
62° starboard track, small gyro angles, spread used insured 200%
coverage of target length. Slowing down of target from first tor-
pedo hits probably accounts for fourth torpedo hitting. This attack
resulted in a counter attack by escorts in which 13 depth charges
were dropped and light aerial bombs by plane after GUAVINA had
returned to periscope depth. Eight bombs were dropped but no damage
was sustained.

3. The rescue of the twelve Army aviators off YAP is most
gratifying and reflects much credit of the good judgment of the
Commanding Officer, U.S.S. GUAVINA. The patrol was terminated early
due to injuries sustained by one of the survivors which required
surgical attention. The pharmacist's mate is congratulated on a
job well done.

4. A total of 42 plane contacts were made, of which 19
were identified as friendly.

5. The excellent results of the SD radar are heartening.
This radar has been fitted with an amplifier unit which is apparent-
ly the answer to a long-felt need.

Report of Second War Patrol.

From: The Commander Task Force SEVENTY-TWO.
To : The Commander-in-Chief, UNITED STATES FLEET.
Via : The Commander SEVENTH FLEET.

Subject: U.S.S. GUAVINA (SS362) - Report of Second
War Patrol, Comments on.

1. The remarks of Commander Submarine Division
ONE HUNDRED SEVENTY TWO are most complete and are concurred
in.

2. On this patrol, spent in the vicinity of PALAU
and YAP, GUAVINA made only one worthwhile contact, which was
skillfully developed into an attack. Three hits for four
torpedoes fired resulted in the sinking of an AK similar to
the ADEN MARU.

3. In performing life-guard services off YAP,
GUAVINA'S careful coverage of the area, and commendable
tenacity of purpose, resulted in the rescue of twelve aviators.

4. This patrol is designated as "Successful" for
the purpose of award of Combat Insignia.

5. The Task Force Commander takes pleasure in con-
gratulating the Commanding Officer, officers and crew of the
GUAVINA upon completion of a successful patrol, and for in-
flicting the following damage upon the enemy:

SUNK

1 AK (ADEN MARU Class - EC)---5,824 tons

6. Since the above damage was accomplished under
the operational control of Commander Submarines PACIFIC FLEET,
he is requested to assume credit accordingly.

                     Range 4000 yards. Began closing targets at full
                     speed. The targets turned toward us as if they in-
                     tended to join us. (Perhaps they thought me a JAP).
                     Lookouts observed several natives on shore rush out to
                     small boats and start heading toward us.
1611(I) Range 3700 yards to rear freighter.
                     "COMMENCE FIRING" Machine Gunners (2-20mm,
                     2-50 cal.) standing by to take care of any possible
                     return small arms gunfire. First salvo - OVER, second
                     salvo - SHORT, third salvo - HIT - on stern putting
                     target out of control. Continued closing range.
                     Freighters both began heading for beach, natives in
                     small boats also headed back to beach. Fired twenty-
                     five rounds more, ten (10) hits. Target now completely
                     out of control, stern knocked off, upper works gone.
                     Range now such that we were closer to leading unengaged
                     freighter. (Forward Machine Gunners had been straffing
                     her) Fired five (5) salvos with two (2) hits at this
                     target which holed her and she started for the beach.
                     This put her behind the first target. Shifted fire
                     back to first target and gave it fifteen (15) more
                     rounds, with five (5) hits. Target was now burning
                     badly, settled by the stern, rolled over to starboard
                     and sunk in the shallow water. Final range to this
                     target 1000 yards. I maneuvered now to close beach and
                     finish off second target. My lookouts had observed that
                     when this ship beached one man had scurried ashore
                     and took to jungle. Fathometer now read 45 fathom,
                     then 35 fathom, radar range 900 yards. (Target on
                     beach) Entire scene of shore, target, etc. clear with-
                     out binoculars. Gave this target twenty (20) more
                     rounds at close range, fifteen (15) hits. She was now
                     burning badly and settling, holed several times and
                     upper works blasted away. This target now destroyed.
1640(I) Two (2) small freighters destroyed. "CEASE
                     FIRE". My position now, 900 yards off the
                     beach in 35 fathoms of water (KATABAU POINT, MINDANAO,
                     Latitude 5-54.4 N. Longitude 124-49 E.). Set course
                     to head out to sea, at full speed.

fact that at 1000(I)/10th. our position
was Lat. 4-41 N. Long. 126-07 E. Having been zig-
zagging on base course North since dawn at speed
seven, on surface with high periscope watch. About
this time we sighted a Liberator aircraft (contact
#35) coming in from the east. He crossed our bow
at about ten miles and continued on to Northwest.
He then appeared to sight us from rear gun posit-
ion and turned around and headed in for us. We
challenged but he did not reply and appeared to
turn away when we flashed light. He made a wide
circle of our position at radar range from 6 to 7
miles, then went on his way out to the Northwest.
These two positions are about 29 miles apart!!
0617(I) Dived.
0631(I) Sunrise.
0654(I) Surface.
0711(I) Sighted (Ship contact #2) shears and
periscopes of what appeared to be one of
our submarines on surface. Started to close him
for better identification, as he was within my 60
mile circle, but he turned away and I was not gain-
ing on him. Then at
0720(I) He DIVED so I reversed course to head
away.
0721(I) Aircraft contact #36, sighted a small
single wing plane in direction where
submarine had been. (Believe the submarine was
"T"GO and had dived for the plane) Was unable to
readily identify plane and had made no previous
contact by V.H.F. voice radio, so did not wait
any longer.
0722(I) Dived.

1100(I) Aircraft contact #39, sighted a Liberator
at 25 miles.
1240(I) Sighted tops of small vessel. (Ship con-

1356(I) Surfaced. Vessel still about same range
and same shape. Closing on the surface.
1447(I) Running at full speed, had closed in on a
small native sailboat with "sampan rig"
sail. Had a "white flag" on small stick
in boat. All crowded in bottom. One spoke
English. When they saw we were holding our fire they
became very friendly. They lowered sail and came
alongside. They all had the definite features of
Filipinos and the one who talked English was very
good. He stated they had left the eastern shore of
Sarangan[UNCLEAR: i] Bay because they had heard our distant
bombing and were going down toward MORO Bay. He
stated that they were waiting for the Americans to
return to the islands and in general they seemed
truly friendly. They had a few coconuts and native
mats and were quite anxious that we accept them. We
gave them a few cans of salmon and they seemed over-
joyed. We tried talking some of them into coming
aboard as "Mess boys" but they were not receptive to
this. The native stuck to a story that there was no
Jap shipping about. Upon departure, there was much
hand shaking with wishes of "Long Life" for us. The
name of the boat was "KAPEL AREN". This was not a
very profitable encounter toward the war effort and
my Commandos were quite disappointed there had been
no action. However it did provide a little diversion
to break up the monotony.
1530(I) Took departure and returned to "Lifeguard"

                     to close targets. Targets passed close
to western shore of BALUT Island (in Sarangani
Island group) at an estimated speed of at least 20
knots. Only the top of one ship and tops and stack
of another ship were ever visible after submergence.
We were bucking the current of Sarangani Strait and
after running at various fast speeds for one hour
on a course to enter the strait, had made good
minus one mile distance.

0730(I) Ship contact #5, sighted smoke of ship on
                     horizon, to the eastward, through SARANGANI
STRAIT. I first believed that the target was round-
ing BUKID POINT and that it intended to come South-
west through the strait. This would be fine, be-
cause I could remain on the surface, track ahead of
him to obtain his course and speed, getting away
from the influence of the currents in the strait
and make a submerged attack on it in the open sea
to the westward.

MINDANAO for "Lifeguard" Duty.
(Continued) His masts were plainly in
progressed it was obvious he was not coming
the Strait and he appeared to be stopped.
0803(I) Aircraft contact "45" sighted the
Jap fighter plane at 12 miles to the South-
west, and he was just skimming along the
horizon and disappeared from view to the Southwest. Remain-
ed on surface "tracking" target.

0830(I) It was now apparent it was my move to
close the target, "bucking the current"
through Sarangani Strait. Set course east and head-
ed in. I knew the current was strong against me so
wanted to make all the progress possible with surface
speed. The target was now coming into view in the
high periscope. All the upper works were now visible.
Our first impression had been it might have been two
or more ships, but it was now seen definitely to be
one large naval vessel. Now the forward turret,
bridge and director, stack, mast and an aft direct-
or were visible. Lowered periscope as the tops could
be seen now from the high lookout platform. Con-
tinued to close until "tops" were visible from
bridge. Took one last quick look with periscope
and at
0920(I) Dived to continue approach submerged.
Range now 15,000 yards. He obviously
was stopped and I felt he was "hiding" from our
planes. During approach, ran deep at fast speeds,
checking progress every half hour with "cuts" on
the nearby islands. These cuts indicated that we
were making progress, slow but sure.
1200(I) We had now identified him as a KATORI CLASS
Cruiser. He was anchored with his stern
toward the beach. The strain on his bow anchor
chain (chain straight out with angle 65° with the
vertical) indicated he must have out a stern anchor
or stern line made fast in the cove in Latitude 05-
34-42 N, Longitude 125-23-30 E. The target was
"swarming" with men. It appeared that their gun
stations were manned. Also there were many men
working over the side. Also there were two ship's
boats in the water running around the ship.
1224(I) In position for attack. Range 2000 yards,
angle on bow 30 starboard. A cut showed
us 1500 yards off the beach and the current was now
setting us "down" on the beach.

1225(I) Fired four (4) steam torpedoes (8 second
interval), gyro angle zero, from bow
tube nest. The first torpedo, aimed amidships, hit
the beach passing astern (to the left) of the target.
I could see the wake of this torpedo and as it ap-
proached and passed the target, the AA battery on
the target began shooting at it. I aimed the later
torpedoes farther forward (to the right). The
second and third torpedo hit the target aft. The
fourth torpedo passed ahead of the target (to the
right) and hit the beach. Having seen the four
torpedoes explode at
1227(I) Fired two (2) steam torpedoes (8 second
interval), gyro angle practically zero.
The first of these torpedoes hit aft causing a
tremendous explosion and huge flames and black clouds
of smoke which rose hundreds of feet in the air.
The second of these torpedoes hit just aft of amid-
ships with another tremendous explosion causing the
flames and smoke to completely engulf the after half
of the target in smoke and flames. The two torpedo-
oes that had hit the beach went off with tremendous
roars and flames. I was now so close to the beach,
that I could make out clearly objects along the
shore so pulled clear to keep from grounding,
observing the progress of destruction to the target.
1300(I) Began easing away from area.
1320(I) Target burning and smoking violently but
still afloat. The current had worked to
carry us 8000 yards from target. I knew I had to
go in again with another attack to "polish her off".
I wanted to get on the opposite bow for this next
attack, so started the long grind against the cur-
rent using the same tactics of running deep with
fast speeds and checking position every half hour.
1600(I) Battery Gravity now 1.140.
1700(I) Battery Gravity now 1.120.
1705(I) In position for a stern shot, on port bow
of target, range 2500 yards. (I thought
current would drift me right down on target) (I
could also see a man in white shirt walking along
the beach) The fire on target was beginning to sub-
side.
1707(I) Current was not acting as predicted as
range was increasing so fired one (1)
electric torpedo. (Gyro 1° right) This missed, pas-
sing ahead of target's bow (to left) and exploded
on the beach.

MINDANAO for "Lifeguard" Duty. (Cont'd)
Fired one (1) electric torpedo, range
3000 yards, gyro zero, aimed to the right
to compensate for current. This torpedo missed and
exploded just to the left of the target's bow.
This explosion acted like a primer causing the fires
to break out with new fury.
1713(I) I now had to come around for a Bow shot
to get this job over.
1755(I) Again in position on target's port bow,
for bow shot. (Angle on bow 35° port)
Fired one (1) steam torpedo, gyro zero, range 1500
yards. (Aiming to right to compensate for current)
HIT - Blew target's bow off.
1756(I) Fired one (1) steam torpedo, gyro 1° right,
range 1400 yards. HIT - Blew up target's
bridge section.
1758(I) Fired one (1) steam torpedo, gyro 2° right,
range 1300 yards. HIT - Blew up target's
mid-section.
1759(I) Fired one (1) steam torpedo, gyro zero,
range 1100 yards. HIT - Blew up target's
stern section. Current was now carrying me down
across the position of the target's bow. Began
swinging hard left to get clear of target and beach.
Swinging right into current would have caused me
to go right into the target.
1800(I) Unable to obtain reading on Battery Gravity.
1803(I) Holding depth nicely at 65 feet.
1804(I) Thump forward, touched bottom, stopped
swinging.
1805(I) Surfaced 300 yards from wreckage, 900 yards
from beach. Clearing area at full speed.
What wreckage was above water was a jumbled twisted
mass. There appeared to be not a sole around in the
water or on the sandy beach. The fire and smoke was
tremendous and still billowing hundreds of feet in
the air.
1830(I) Observed and heard a tremendous explosion
and the remains of the target were hurled
high into the air and fell burning in three separate
masses.
1840(I) Sunset.
1900(I) Sent Guavina's #5 message to CTF-72 giving
data on the sinking of the target.

COMMENT #1:
My estimation of the situation is as follows:-
(a) I had observed the target rounding
BUKID POINT.

B. NARRATIVE. (Cont'd)

COMMENT #1:
My estimation of the situation is as follows:(Cont'd)
(b) Target anchored and the smoke puffs
we continued to see were caused by
engine changes which accompany anchoring
and mooring.
(c) Target put his stern into COVE at
PACUBAS (Lat. 05-34-42 N. Long. 125-
23-30 E.) by "carry in a stern anchor or
by making a stern wire fast ashore.
(d) As approach progressed, the target
appeared to get closer to the land,
indicating the target was "walking back"
on its Bow Anchor.
(e) I observed the Bow Anchor cable
stretched out ahead at an angle of
about 65° with the vertical with a heavy
strain on the cable.
(f) A large portion of the target's crew
were at gun stations.
(g) The target was attempting to conceal
itself in the COVE.
(h) The men over the side of the target
were either painting or attempting
to camouflage the ship.
(i) The small boats were in contact with
the beach probably tending lines.
(j) One boat was alongside aft at time
of first torpedo hitting target aft.
The other had cleared side of target a
few seconds before.
(k) My attack caught the target entirely
by surprise.
(l) Many of the crew were probably lost
in the tremendous explosions and fire.
(m) I observed one man walking along the
beach just before the first late
afternoon attack. He was not around
after electric torpedo exploded on beach
near him.
(n) Upon surfacing observed not a sole
around wreckage or as far as could be
seen on the beach.
(o) Twelve (12) torpedoes (10 steam - 2
electric) had been fired at the target,
with 8 hits.
(p) Unpredictable currents had caused
misses, but the misses had been used
to good advantage to "SPOT ON" the other
torpedoes.
(q) The first four hits severely damaged
the Cruiser.

COMMENT #1:
My estimation of the situation is as follows:(Cont'd)
(r) The last four hits had completely de-
stroyed and disintegrated the target.

COMMENT #2:
The grounding at 65 feet proved to my
advantage because it forced me to sur-
face and clear the area. Thus we were well
clear of the target when it exploded and
erupted into the air at 1830(I). I am glad
I was not submerged, near at hand, when
that happened.

Thus Endeth "D" Day.

September 16, 1944 In Sixty mile circle from SUMBANG POINT,
MINDANAO for "Lifeguard" Duty.
0022(I) Ship contact #6, sighted small vessel at
range 3500 yards. Unable to identify type,
perhaps some kind of small trawler. Tracked around
him for a short time. Not able to see him very well
in the hazy dark night. Radar ranges would fade
out beyond 3500 yards. "Pip" on radar screen gave
impression it was a wooden hull.
0045(I) Fired one (1) steam torpedo, set at 2 feet,
gyro angle zero, at range 1700 yards,
"down his throat". Torpedo curved slightly to left
and missed.
0046(I) Fired one (1) steam torpedo, set 2 feet,
gyro angle 5° right, at range 1200 yards,
angle on bow 5° starboard. Torpedo missed slight-
ly to left. By this time my "Better Judgement" took
charge and I realized I was shooting at a "spit
kit" and was wasting torpedoes. I still wanted to
sink JAP ships, but this "spit kit" was not a
"torpedo target". As I turned clear of the craft,
at 700 yards, I could see it was a small fishing
type.

The night was dark and hazy and I knew
gunners could not see such a target in
the gun sights so did not resort to a gun action.

Heard both torpedoes explode at end of run.

bearing 225° T. from SUMBANG POINT.
0631(I) Sunrise.
0845(I) Aircraft contact #46, sighted enemy fighter
at 6 miles. DIVED. This is same small
fighter we have seen several times before.

C. WEATHER:
The weather during the major part of the patrol was excel-
lent. Seas were usually glassy calm with skys clear to partly
cloudy. Had few days with wind a moderate breeze with a few
rain squalls.

D. TIDAL INFORMATION:
The currents around DAVAC GULF AREA, SARANGANI STRAIT,
and SARANGANI BAY AREA were found to agree with information
contained in Coast Pilots and data shown on charts. It is to
be noted that the currents in Sarangani Strait are varied and
strong. Fast speeds are necessary when operating submerged
in the strait to make the slightest progress.

E. NAVIGATIONAL AIDS:
The charts of the entire area are very accurate. The
land marks in the area are numerous and prominent, making
Piloting easy.

U.S.S. GUAVINA(SS362) Gun Attack No. 1.
Patrol No. 3.

Time: 1607(I) to
1640(I) 8/31/44
Between:
Lat. 05-52(N)
Long. 124-36(E)
Lat. 05-54.4(N)
Long. 124-49(E)

TARGET DATA - DAMAGE INFLICTED

Sunk:
Two (2) small coastwise freighters - 500 tons
each. These resembled the ship shown in:
"War and Navy Dept. Recognition Journal", No. 11
dated July 1944, page 28. ("Engine-Aft Coaster")

Damage
Determined:
One freighter was hit by sixteen (16) salvos of
4" H.C. ammunition. The stern was blown off, the
upper works blown off, she settled first by the
stern then rolled over to starboard and lay with
an angle of about 140° from vertical in the shal-
low water where she sunk. The other freighter was
hit by two (2) salvos which started her on fire
and began settling. Her crew beached her at
KATABAU POINT, MINDANAO, Lat. 5-54.4(N) Long. 124-
49.0(E). Closed range to 900 yards and hit her
with fifteen (15) more 4" salvos, which caused her
to settle more and had her completely on fire.
She continued to burn violently as long as could
be seen as we cleared away from the area.

DETAILS OF ACTION

Guavina
Gun
Armament:
One (1) - 4" deck gun.
Two (2) - 20mm machine guns.
Two (2) - 50 Cal. machine guns.

Ammunition
expended:
62 rounds - 4 inch H.C.
6 rounds - 4 inch Common
1600 rounds - 50 Cal.
480 rounds - 20mm.

Average range 1200 yards. The High Capacity
shells were very effective against these two
targets. Radar range was used for the opening
range, and "Spotting" from then on to keep "On"
the targets. The sea was calm and the rate of
fire was slow, but each shot was well directed.
The targets did not have much speed and were
somewhat restricted in their movements (The only
direction they could go was toward shore) so they
were unable to maneuver to avoid my fire.

TORPEDO ATTACK FORM

U.S.S. GUAVINA (SS362) Torpedo Attack #1 Patrol No. 3

Time: (a) 1225-1226(I) Lat. 5-34-42(N)
      (b) 1707-1710(I) September 15, 1944 Long. 125-23-30(E)
      (c) 1755-1759(I)

TARGET DATA - DAMAGE INFLICTED

Description: KATORI CLASS CL (18-20) as shown ONI 41-42.
             It appeared to have much more Anti-Aircraft
             armament forward of bridge and on deck structure
             aft of bridge, than is shown in pictures.

             Contact was made, at 0730(I), September 15,
             1944, while surface patrolling, on "Lifeguard"
             station for D-Day, by sighting smoke on the
             horizon to eastward through Sarangani Strait,
             at range fifteen miles, as the target rounded
             BUKID POINT, MINDANAO. Target anchored and
             put his stern into COVE at PAGUPAS (See U.S.C.
             & G.S. Chart 4608). Conditions of visibility -
             Excellent.

Damage: Target completely destroyed and sunk.

Determined By: (1) At 1225(I) four (4) hits aft, (TORPEX heads).
             These hits caused tremendous explosions which
             engulfed the after half of target in billowing
             flame and black smoke that rose hundreds of feet
             in the air.
             (2) At 1707(I) One electric torpedo (TORPEX head)
             exploded just off target's bow which caused fire
             to burn with new fury.
             (3) From 1755(I) to 1759(I) four hits (TORPEX
             heads).
                  (a) First HIT - Blew bow off.
                  (b) Second HIT - Disintegrated bridge
                                    section.
                  (c) Third HIT - Demolished midship section.
                  (d) Fourth HIT - Hit in flaming wreckage
                                    of stern.
             (4) At 1805(I) Surfaced 300 yards from wreck-
             age and observed a jumbled mass of charred, burn-
             ing ruins (that portion above water).
             (5) At 1830(I) Observed remains explode and
             erupt into the air and settle in three burning
             masses.

Target Draft: 19 Feet. Target anchored. Firing Range:
             (a) 2000 yds, (b) 2900 yds, (c) 1400 yds.

OWN SHIP'S DATA

Speed: 3.4 knots         Courses: (a) 050°(T)         Depth - 65 feet
                         (b) 175°(T)         Angle - 0
                         (c) 350°(T)

FIRE CONTROL AND TORPEDO DATA

All firing was done with periscope bearings,
keeping the ship headed in such direction to keep
the gyro angles as close as possible to zero.
The first salvo of four (4) steam torpedoes were
fired with an eight second firing interval.
Having seen what the current did to this salvo,
I corrected, (by periscope bearing) and fired a
salvo of two more torpedoes, which hit because of
current correction applied.
One electric torpedo was fired at about 2500
yards. Because of it's slower speed and the
long range, current caused a wide miss. Based
on this "miss" a second electric torpedo was fired,
range 2900 yards. This torpedo just missed. The
correction had not been enough.
Four more steam torpedoes were fired individually.
I had the current correction under control now.
Each torpedo hit where I intended it to hit.
All torpedo explosions were observed through the
periscope. All torpedoes ran HOT, straight and
normal.

FIRE CONTROL AND TORPEDO DATA

The less said of this attack the better. I
had fired the torpedoes before I had done too
good a job of identifying the target. Briefly,
it can be summed up in three words, "I was too
eager".

I. NO MINES WERE ENCOUNTERED.

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS.

No anti-submarine measures were encountered.
No evasion tactic needed.

K. MAJOR DEFECTS AND DAMAGE.

When the ship touched bottom at 1804(I), September 15,
1944, while submerged at sixty-five (65) feet, following
the sinking of the KATORI CLASS CL, both sound heads appar-
ently hit. The heads were damaged to the extent that each
is completely grounded out. The "training" shafts were also
bent so that neither can be "rigged in" and both train with
extreme difficulty. The ship was surfaced at 1805(I) (im-
mediately after touching) so that no other part of the hull
touched bottom.

The mast for the SJ radar has an extremely noisy gear
assembly in the rotating mechanism. It appears to be a
misalignment which does not allow the bevel gears to mesh
properly. This was noted three days after departure on
patrol and the noise has gradually increased throughout the
patrol. The radar mast also vibrates an excessive amount
during submerged runs which creates a loud rattling noise
at submerged standard speed. Apparently shaft bearings are
worn at some point. This will be remedied during next refit
at Brisbane.

The following remarks are relative to a former un-
satisfactory condition:
Oil expander rings were installed in the oil rings of
all main engines during the last refit. The results are
magnificent. The characteristic exhaust smoke of the
engines is now gone and the lub oil consumption has been
greatly reduced.

I. RADIO.

In DAVAC GULF area, we were unable to copy the Belconnen
Schedules between 0300 and 0600 GCT. At all other times, re-
ception was good. Ship to shore transmissions were made with
no difficulty.

M. RADAR.

Plane contacts on the SD radar ranged as far as seventy
miles. Good results were experienced on low flying aircraft.
The SJ radar performed well, picking up land at fifty miles,
a light cruiser at twenty thousand yards, submarines at eleven
thousand yards, and trawlers at five thousand yards. In a
gun attack both the projectile in flight and resulting splash
could be observed on the radar screen. The sending of re-
cognition signals by keying the SJ radar was tried with no
results. The SJ radar was also used effectively for piloting
at night.

The following types of radar interference were encount-
ered on the SD radar during this patrol:

TYPE ONE:

Pulses of closely spaced railings rise from the sweep.
These look somewhat like patches of grass but seem to be
rounded on top indicating that it is possibly modulated.
The amplitude varies but all the interference is visible on
the sweep. In most cases it sweeps across the screen from
right to left in about three second sweeps. This type of
interference was very common about 50 miles from Japanese
held islands. Presumed to be Japanese Land Based Radar.

TYPE TWO:

Very closely spaced railings appear suddenly and extend
from the sweep over the top of the scope. These railings do
not move across the screen but remain relatively constant
until they suddenly disappear. This interference comes and
goes at irregular intervals. Most of the interference was
seen very near the contact of American Liberators. Probably
American Aircraft radar.

TYPE THREE:

The sweep becomes very distorted. The sweep appears to
move in various shapes that are similar to sine waves. Some-
times the sweep would remain steady except that it would be
shaped as a sine wave instead of a straight line. Presumed
to be voice transmission from planes.

M. RADAR (Cont'd).

TYPE FOUR:
A single railing rises from the sweep and moves across
the screen usually from right to left. This is sometimes
seen when our own SJ is in operation. This type of inter-
ference is probably due to some other SJ on an American
Submarine.

TYPE FIVE:
Sweep moved up and down on the scope. This is due to
C.W. transmission of some transmitter somewhere in the
vicinity.

SJ RADAR INTERFERENCE
(Cont'd)

9/7 00-48N 125-59E Same as 9/6. Direction appeared to come
from the Sangi Islands group.
9/8 00-47N 125-37E Lacy pulses of grass moving across
sweep. Probably aircraft radar. Ap-
peared suddenly and duration of inter-
ference was short.
9/11 05-23N 124-53E Railings on "A" scope. Sine waves
and curved bright lines on the Bear-
ing 270 T. Probably another SJ.

N. SOUND GEAR AND CONDITIONS.

Sound conditions were excellent. On a heavy target pro-
ceeding at a speed greater than twenty knots, ranges of ten
miles or more were obtained. Small craft could be heard be-
fore they were visible. In the approach on the light cruiser,
none of her ship noises could be heard due to the background
noise of the shore line.

O. DENSITY LAYERS.

In the southern Mindanao area a negative gradient with
a two degree temperature drop between the surface and 300
feet generally prevailed. On September 9, in Lat. 01-33.5N.
Long. 125-52.8E. there was the usual two degree drop down to
280 feet. Between 280 and 340 feet there was a sharp negative
gradient with a temperature drop of eight degrees.

F. NARRATIVE. (Continued)

November 15, 1944
2222(T) Fired one forward (steam) torpedo, gyro
angle zero, depth 4 feet, range 1950 yards,
track angle 150° port. Observed torpedo run down
track at:
222320(T) Hit target amidships. This caused a tre-
mendous explosion and the target burst into
violent flames. Looks like she is carrying some
aviation gasoline. She began to settle forward, list-
ed to starboard and twisted around to present an angle
of 140° starboard.
This had been a clear dark night but now the area was
completely illuminated and the target was plainly
identified as a medium AP.
222415(T) Fired one forward (steam) torpedo. This
torpedo ran erratic to the left (was set for
zero run and 4 feet) and exploded at end of run.
222615(T) Fired one forward (steam) torpedo, gyro
angle zero, depth 4 feet, range 1400 yards,
track angle 135 starboard.
222710(T) Hit amidships. A tremendous explosion.
Ship broke in two and sank immediate-
ly. Also pip disappeared from radar screen. Area
still illuminated by oil fires on the water.
After first torpedo hit the area was completely il-
luminated by fires and the entire scene was clearly
visible to the entire bridge watch.
2228(T) Cleared area to the northwestward, going
along coast in search of more possible
targets.
2250(T) SJ radar "pip" at 6,000 yards. Closed in
but could not sight it at 3,000 yards.
This indicated very small target. Decided this not
a torpedo target and too dark for any identifica-
tion.
2357(T) SJ radar "2 pips" at 6,000 yards. Smaller
than previous contact. These not sighted
at range 2800 yards. Decided these not torpedo tar-
gets. Proceeded. No further contacts along coast in
Mindoro Strait. (East Apo Pass).

November 16, 1944 Proceeding westward through South China Sea
north of Dangerous Ground.
0200(T) Sent message to CTF-71 regarding sinking of
AP.
0220(T) Exchanged recognition signals via SJ radar
with HADDO.

November 20, 1944 On station in northwest approaches to
                      TIZARD'S BANK. (Submerged day patrol)

November 21, 1944 On station in northwest approaches to

November 22, 1944 On station in northwest approaches to
                      TIZARD'S BANK. (Submerged day patrol)
1640 (T) Sighted masts of ship, (Range 14,000 yards),
          across and behind the island of TIZARD'S
          in TIZARD'S BANK. Ship was on a southwesterly course.
          It came out from behind the island, made a fast turn
          to the right, reversing course. Tracking then in-
          dicated she was stopped. She had probably anchored.
          (Latitude 10-22N, Longitude 114-21E). This position
          puts her inside the reef of TIZARD'S BANK. I maneuver-
          ed for an attack position from the southwest of the
          ship. The ship is a TANKER; raked bow, mast, bridge,
          tall post, mast, stack, counter stern, resembling
          MUZISA MARU, page 255 ONI 208J.

          (Steam) torpedo, gyro angle zero, depth
          set 3 feet, track angle 165° port.
183710(T) I saw torpedo hit and explode (ON TGT)
          giving a flash of flame and clouds of
          black smoke.
1839 (T) Fired one FOW (Steam) torpedo, range 2650
          yards, gyro angle zero, depth set 3 feet,
          track angle 165° port. Then began turn in with full
          right rudder to clear reef.
183925(T) Saw and heard torpedo hit and explode
          (ON TGT) with flash of flame and more
          black smoke clouds.
1843 (T) Surfaced. Target still in sight. I man-
          euvered for another bow shot. Ship was
          plainly seen by bridge watch and a periscope obser-
          ver and also there is a large "pip" on SJ radar
          screen.
1855 (T) Target was plainly seen, by all observers,
          to sink. Ship disappeared from screen.

0750(I) On station in northwest approaches to
          TIZARD'S BANK. (Submerged day patrol)
          Sighted ship, range 10,000 yards, bearing
          170° (T) off Island in TIZARD'S BANK. (This
          ship was in the very near vicinity of last night's
          tanker sinking and he was not there then.) Tracking
          indicated it to be inside the reef and the ship was
          stopped. We made approach from the southwest. Identif-
          ied ship as a large AK; raked bow, flush deck, goal
          post with top mast, kingpost, composit superstructure,
          two goal post with top mast, stern partially blown
          away by a bomb hit. The stern was very rusty and it
          appeared to be an old scar. Anchorage position:
          Latitude 10-22-30N, Longitude 114-22E. We made approach
          from southwest and at:
1003(I) Fired one steam (FOW) torpedo (FOW POWER),
          depth 3 feet, gyro angle zero, depth 3 feet, track angle
          50 port, range 5500 yards. This torpedo missed. As
          we were within 1000 yards of the reef between us and
          the target and as I did not care to fire anymore long
          shots from this spot, proceeded around island and
          obtained a position to the northeast of the island
          which proved to be a better spot.
1413(I) Came to SJ radar depth. Range to target
          5200 yards. Managed to find a low spot in
          the reef where the after end of the target protruded
          beyond. Approaching the reef to about one mile out
          in position 3500 yards from target. At
1433(I) Fired one steam (FOW) torpedo, depth set
          3 feet, gyro angle zero, range 3500 yards,
          track angle 115° starboard. There was a heavy swell
          running and the torpedo was observed to broach frequent-
          ly as it ran down the range and was further seen to
          pass astern of the target.
1436(I) Fired one steam (FOW) torpedo. Depth set
          5 feet, gyro angle zero, range 3100 yards,
          track angle 115° starboard. Began swinging hard right
          to get clear of the reef. This torpedo was observed
          to run true down its course just clearing the breakers
          at the end of the reef and at
1438(I) Was observed to hit target between stack
          and after mast. There was a tremendous ex-
          plosion and target was engulfed in smoke.
1439(I) Smoke cleared away, target had rolled over
          on its starboard side, sank stern first,
          leaving only a small portion of Bow held up by the
          reef, which was still visible above the water.
          Target had been destroyed.

November 24, 1944 On station in northwest approaches to
                    TIZARD'S BANK. (Submerged day patrol)

November 26, 1944 Proceeding to patrol station off China
Coast.
0200(T) Made contact with FLOUNDER and exchanged
signals.
0930(T) Sighted float plane, dived.
1022(T) Surfaced.
1111(T) Sighted float plane again. Dived. We are
in sight of CAPE VARELLA; Indo China.
1555(T) Surfaced.

November 27, 1944 On station off CAPE VARELLA, Indo China.
(Submerged day patrol)
1145(T) Sighted float plane.
1910(T) Sighted three ships, which developed to
be three small sailboats on southerly
course. On first sighting sent "Contact message"
to FLOUNDER and RASHER. Upon definite identificat-
ion sent a "cancel" message to FLOUNDER and RASHER.

November 28, 1944 On station off CAPE VARELLA, Indo China.
(Submerged day patrol)
0938(T) In position 7 miles bearing 035°(T) from
CAPE VARELLA light. Sighted 3 ships round-
ing Cape, hugging coastline proceeding northerly.
Ships were, one large tanker (Naval Auxiliary) and
two Chidori type escorts. Tracking indicated speed
in excess 15 knots. Maneuvered for attack position
but able to get only 5000 yards from rear escort.
The tanker was proceeding about one mile off the
shore line and the two escorts were one escort on
the starboard bow and starboard quarter of the tanker.
1030(T) Sighted single wing, double float scout
plane over formation heading for us. Do
not know if he "spotted" us or not.
1103(T) Targets had passed and were now hull down
over horizon. Broke off approach. Target's
speed precluded the chance of us surfacing tonight
and making "end around".
1405(T) Sighted smoke of ships coming over horizon.
This developed to be one AK and one small
escort coming southward along coast and would be
rounding CAPE VARELLA. Tracking indicated speed
(10 knots). A small twin float monoplane was observed
circling over the targets. Maneuvered to gain attack
position. Ships were identified (30) One medium AK
(Characteristics: Raked bow, raised forecastle and
stern, two masts centered on the fore and after decks,
composite superstructure and heavily loaded) One
Chidori type escort (had a whale boat bow with a 3"
gun forward).
1447(T) In position. Latitude 12-52-30", Longitude
109-20-00". (This is two miles off the beach.
Target is ½ mile off the beach).

144700 to Fired salvo, three steam (Fow) torpedoes,
144722(T) range 3200 yards, gyro angle zero, depth
4 feet, track angle 100 port, using a spread
(periscope offset) with continuous check bearings.
144730(T) Swung hard left to get clear of beach
and out into deep water.
1447(T) Sighted float plane sliding in on us.
144730(T) One CLOSE aerial depth charge. Ship
rattling like an old tin can with a pebble
in it. Escort then started down.
144807(T) One torpedo explosion. (On time)
144817(T) One torpedo explosion. (On time)
Sound had clearly followed target's screws,
heard torpedoes run true, heard torpedo explosions,
noted tremendous definitely stop, then heard tremendous
explosions, as if the target had been loaded with
ammunition. There followed very loud characteristic
breaking up noises. The target definitely sunk.
1451(T) Bow nudged the bottom at 200 feet.
1456(T) Started to come up for look.
1457(T) At 100 feet. Escort, that was close. The
escort must be carrying depth charges. Gave
up idea of looking. Based on down to 100 feet to run
close to bottom out to deep water.
1457(T) Two more close depth charges.
1510(T) One more (not too close) depth charge.
Escort then lost us and we proceeded away
from area.

November 29, 1944 On station off CAPE VARELLA, Indo China.
(Submerged day patrol)
0015(T) to Made rendezvous with FLOUNDER and BASTAW.
0200(T) Exchanged signals and dope. Then proceed-
ed back to assigned station.

November 30, 1944 On station off CAPE VARELLA, Indo China.
(Submerged day patrol) Sighted numerous
"JUNKS" today both north and southbound along the coast.
Also sighted twin float monoplane scout today, as usual.
2230(T) Received message to proceed to position for
offensive patrol on line between
BAY and CROSS Shoals. Our position in general
vicinity eight miles from HON GUM Light.

December 1, 1944 On station off KAMRANH BAY. (Submerged
day patrol) Sighted three float plane
scouts over the Bay today.
1425(T) In position Latitude 11-43(N), Longitude
109-20(E). Sound heard "pinging" to north-
ward. This developed to be a formation of 4 large
tankers and 6 (Chidori) DD escorts. The tankers were
in loose column proceeding along, about two miles off
shore.

December 1, 1944
     The 6 DD's were to seaward of the formation ranging
     forward of the bow of the leading tanker to the stern
     of the rear tanker. The land formed a perfect screen
     on the one side (Stbd) of the tankers and the 6 DD's
     formed a perfect screen to seaward (Port side) of
     the tankers. The DD's were all "pinging" and my
     sound operators noted them to be each on a different
     frequency ie: 14 - 15 - 16 - 17 - 18 - 19 Kcs. A
     twin float monoplane was also observed screening over
     the formation. Attempted to gain position for flank
     attack on tankers, but only able to close range to
     6,000 yards. Tracking indicated speed 15 knots.
     Our position now is just off the southern entrance
     to KANPAH BAY, Latitude 11-43-30(N), Longitude 109-
     00-00(E), in 45 fathoms water. It appeared that one
     of the center escorts would come within torpedo range,
     so began maneuvering for stern shot (electric torpedo)
     on this one.
     1525(F) At range 3000 yards this escort stopped to
             listen then started shortsea "ping" as if
             he had a contact on our bearing. (We were at 75 ft.
             at the time, twisting for the stern shot, so could
             not see him).
     1529(F) Rigged for silent running and went to 200 ft.
             The formation could be heard to pass to
     southward.
     1533(F) Our immediate opponent then started up again
             as if he had no more interest in his "pos-
             sible contact" and continued with the formation (We
             had gone through a "lever" at 180 ft.).
     1555(F) At periscope depth again. Convoy has passed
             over horizon to southwest.
     2130(F) Received message "reconnaissance assignment"
             had been delayed. Proceeding back to
     station off CAPE VARELLA.

December 2, 1944 Proceeding to station off CAPE VARELLA.
     0130(F) Exchanged signals with FLOUNDER. He is
             enroute base due low fuel supply. "Pack"
     now consists of GUAVINA and BASSLAW.
     Running day submerged patrol off CAPE VARELLA.

December 3, 1944 On station off CAPE VARELLA. (Submerged
     day patrol). Weather "picking up" during
     day. Surfaced in heavy seas. (Waves 25 feet high)

December 4, 1944 On station off CAPE VARELLA. (Submerged
     day patrol). Weather still "whooping it up."

December 5, 1944 On station off CAPE VARELLA. (Submerged
     day patrol). Weather moderating slight
     amount. Still heavy seas running.

Moderate seas now.

December 7, 1944 On station off CAPE VARELLA. (Submerged
2330(I) day patrol) Heavy rains all night long.
Made contact with BASTAW. Exchanged

again. Heavy seas.

December 9, 1944 On station off CAPE VARELLA. (Submerged
day patrol) Stormy weather. Heavy seas.

December 10, 1944. On station off CAPE VARELLA. (Submerged
day patrol) The heavy seas have started
to moderate.

December 11, 1944 Proceeding back to station off KAMRANH BAY,
Indo China as a unit in an Offensive Recon-
naissance line, that line is established between
KAMRANH BAY and FIERY CROSS SHOALS (DANGEROUS GROUNDS).
The weather has again started to moderate. During
this past week of stormy weather have experienced
strong currents which follow closely the coast line
(Velocities up to 3 and 4 knots in a general souther-
ly direction). With continuous stormy cloudy weather
the SJ radar has been the sole means of establishing
position on land objects.

December 12, 1944 On station off KAMRANH BAY. (Offensive
reconnaissance). (Submerged day patrol)
Weather calmed down during day to fairly calm by even-
ing. Still rainy and overcast.

December 13, 1944 On station off KAMRANH BAY. (Offensive
reconnaissance). (Submerged day patrol)
Weather almost clear now. Able to get in toward the
land and obtain fixes today.
1315(I) Heard one distant explosion. (Sounded
like depth charge or torpedo explosion.)
1545(I) Heard "pinging". Maneuvering to close
position.
1615(I) In Latitude 11-50(N), Longitude 109-25(E)
sighted one PC type patrol boat, range
6,000 yards. He was apparently on station outside
KAMRANH BAY and was making a routine sweep. Not a
torpedo target so maneuvered to keep clear.

R. NARRATIVE. (Continued)

December 13, 1944
1730(M) Patrol boat out of sight. Unable to hear
anymore. "pinging".

December 14, 1944 On station off KARATSU BAY (Offensive
0550(M) reconnaissance). (Submerged day patrol).
Contact with the patrol boat. Radar range
10,000 yards. Dived to keep clear of him.
He is a persistent "pinger" cruising around outside
the harbor entrance to about the 50 fathom curve. I
am able to see him at ranges of about 6,000 yards.
However his pinging is clearly audible all morning.
There is also the usual float plane scout planes
on station over the outer harbor entrance.
Plotting has indicated a current of 2.5 knots set
200° T. Have been heading in northerly direction
as much as possible to just about "hold own position."
1113(M) (In position Latitude 11-44', Longitude
109-26W.) Sighted a formation of ships
bearing 200° T., estimated range 25,000 to 30,000 yards.
This proved to be an enemy task force consisting of
two (2) FUSO or NAGATO type BB, two large and two
medium sized DD. Three float planes were screening
formation.
1120(M) One plane "zoomed in" close, low altitude,
angle on bow zero. Went deep for 10 mins.
Do not believe he saw us.
1132(M) Back at periscope depth. Planes over form-
ation but not near us.
1152(M) The formation was all still "hull down" in
the direction of KARATSU BAY and at this
observation the grouping of the ships was such that
masts indicated there might be eight ships in the
formation. Throughout the "FUSO" masts of the two
BB were very pronounced and the masts of the smaller
ships were DD type in general. This is only time
that possibly 8 ships were sighted as a whole in
one observation.
1200(M) (In position Latitude 11-44', Longitude
109-25W.) The formation consisting of two
BB and 4 DD was definitely observed (estimated range
14,000 yards) to pass north across the entrance to
KARATSU BAY and proceed close along shore and going
out of sight well to the northward of KARATSU BAY.
The harbor patrol boats were still "pinging" during
all this. At one time one DD "let go" with a few
"pings" which indicated him tuning his equipment.
Otherwise not one "ping" was heard from the formation.
1222(M) The tops of the two BB's were last seen
bearing 336° T. well to the northward of
KARATSU BAY. Tracking indicated a speed of about 17
knots for the formation. We remained in vicinity to
see if any more units were following.

1300(T) Pagan heading out to sea in order to sur-
        face to send "contact report". Patrol
        boat still actively "pinging" off the entrance.
1530(T) Sighted four (4) engine enemy seaplane.
1613(T) Now about twenty miles from land. Will
        surface to send "contact report".
1614(T) SD mast out. "All clear" "Surface"
1615(T) SD contact 10 miles, closing fast. Had
        not even otter hatch open. Submerged
        again. Hope he did not see us.
1903(T) Surfaced. Sent contact message.

December 15, 1944 On station off KAMRANH BAY. (Offensive
        reconnaissance) (Submerged day patrol).
        The usual patrol planes and patrol craft observed
        functioning off harbor.
1230(T) Small land based monoplane "Zoomed in"
        close over the water. Went deep for 20
        minutes. Believed he did not see us.
1420(T) Heard another set of "pinger".
1430(T) In position Latitude 11-50(N), Longitude
        109-24(E). Observed only extreme tops of
        a ship (mast, stack mast, an AK) bearing 270 T.,
        estimated range 18,000 yards. He had apparently come
        in from the south, hugging the coast and was seen to
        definitely enter KAMRANH BAY.
2300(T) Received instructions to remain on station
        as follows: Off Kamranh Bay north of a
        line drawn 090° T. from HON CHUT Light. MINCO is
        assigned station south of this line.

December 16, 1944 On station off KAMRANH BAY. (Offensive
        reconnaissance) (Submerged day patrol).
        The usual plane and patrol boat observed to be on
        station also.
1136(T) In position Latitude 11-55(N) Longitude
        109-24(E), heard "pinging" and sighted
        masts of ship (an AK) bearing 271° (T). He was hull
        down over horizon, angle on bow 90 starboard. It
        showed the ship was proceeding north hugging the
        coast. The current today checks again 2.5 knots, set
        200 (T). From my position I was unable to gain an
        attack position. Two "pingers" could be heard in-
        dicating two escorts. (These were different "pingers"
        from the patrol boat). At one time the tips of masts
        of two other ships were sighted, one forward and one
        aft of the big ship. The big ship had mast, stack
        mast, stack (painted gray), mast, Kingpost. Probably
        was a large AK.
1215(T) Still "Hugging coast", ship passed out of
        sight to the northwest.

December 17, 1944 On station off KAIRATH BAY. (Offensive
reconnaissance) (Day submerged patrol).
Received message during night that "DACE would re-
lieve us at 2000(H) seventeenth, whereupon we return
base." Wind and weather has picked up during the
night and a fair sea is running. We are just able
to "hold our own" heading into the northerly current.
This allows a "stationary patrol" just off the north-
east approach to the Bay (A fine position for observ-
ing the harbor entrance).
2000(H) Received message from DACE he would be late
arriving station to relieve us so will re-
main on station.
2215(H) In latitude 11-56-30(N) longitude 100-
27-00(E). Had SJ radar contact at 14,000
yards, bearing 238° (T). Tracking indicated course
north.
2240(H) SJ radar contact at 13,660 yards, bearing
201° (T) with a second target. Tracking
indicated course north, speed 9 knots. "Pip" on
radar indicated this to be bigger target. Heavy seas
running from the north and it was requiring 4 engines
to make good 10 knots into it. Taking green seas
over the bridge.
2315(H) Second target was beyond our range so de-
cided to work on first target after all.
Continued to gain position ahead, slowly.

December 18, 1944 Making approach on target.
0331(H) In position for shooting. Range 1000 yds,
gyro angle zero, 30° port track, torpedoes
set 10 feet. (Target still unidentified).
0332(H) Fired two (2) steam (BOW) torpedoes
(Intend firing spread of 4 but during
firing observed target zig hard left.) Target now
identified as a DE type.
0332(H) Swinging hard left for a stern shot.
0334(H) Fired (4) electric (STERN) torpedoes, range
1200 yards, gyro 170° T., 90° starboard
track. Torpedoes set at 8 feet, because of heavy
seas.
0334(H) Target began flashing "red light" in our
direction. Set up was good but no ex-
plosions. Believe torpedoes passed under target.
This was proving to be a fruitless expenditure of
torpedoes because of the heavy seas. Target did not
"engage" us. Cleared area to the southeast.
0520(H) Dived on station.
0630(H) Heard "pinging". Probably one of our
night's targets coming back. This is not
the same "pinger" as the former harbor patrol boats
we had encountered.

December 18, 1944
0713(T) Sighted and heard pings of second ship.
          This was definitely the DE type I had seen
          in the dark when shooting. Both ships proceeded down
          off the entrance to Kamranh Bay.
1756(T) Surfaced in heavy seas tonight.
1930(T) Exchanged signals (via SJ Radar) with
          PBY.
2045(T) Received instructions to return to Base.
2100(T) Proceeding to Base.

December 19, 1944
Enroute Fremantle, Australia via prescribed
routing.

December 20, 1944
Transit Karimata Strait.

December 21, 1944
Proceeding through Java Sea.

December 22, 1944
Proceeding through Java Sea to Lombok
Strait.
2145(T) Began transit of Lombok (current against
          us).
2200(T) In position Latitude 8-25(S), Longitude
          115-52(E) the SJ radar had contact at
13,000 yards, range closing rapidly. It had to be
a plane. A PBY (Black Cat) flew over at about 2,000
feet elevation going north. Noted radar interference
but he did not bother us.
2240(T) In position Latitude 8-32(S), Longitude
          115-49(E) another SJ radar contact at
13,000 yards. This another plane. Then a second PBY
(Black Cat) flew over at about 3,000 feet elevation
flying north. We did not bother us.
2330(T) In position Latitude 8-47-30(S), Longitude
          115-43-30(E) a shore battery at about posit-
ion Latitude 8-47-30(S), Longitude 115-43-00(E) open-
ed fire on us. The first salvo (two rounds) splashed
astern in our wake. We were on in range but enough off
in deflection to miss. The gunflash, the boom and
the hissing of the shells were very pronounced. In
this position we were in most difficult "rip tide"
water so did not want to dive. We had been "bucking
current" throughout and I would have been swept back
into the straits if I dived. So began radical
maneuvers (all engines were on full ahead and we
were making 20 knots).
2335(T) Second salvo (two rounds). Splashed
          astern. Continued clearing area to southward. At
          this same period our radar detector picked up strong
          radar interference which continued for about 15 minutes.
          No more salvos. I hesitate to estimate the gun caliber.
          The splashes astern were BIG but under the circumstances,
          I guess any splash at all would have looked BIG.

C. WEATHER.
     The weather for the major portion of the patrol was poor,
ranging from squally to violent storms; seas twenty-five to
thirty feet high and winds of force seven. The weather ex-
perienced was very much the same as that described in the
Coast Pilot except that the violence and duration of the storms
was more than anticipated.

D. TIDAL INFORMATION.
     The currents experienced during this patrol were similar
to those described in the Coast Pilot. The currents in the
vicinity of Tizard's Bank were of no consequence. During com-
paratively good weather off the coast of Indo China, the cur-
rent set southwest at 1½ to 2 knots. During the height of a
storm, a southwest current of 3½ to 4 knots was experienced,
this being influenced directly by wind and sea.

E. NAVIGATION.
     No remarks.

TARGET DATA - DAMAGE INFLICTED

Description: Target was sighted through periscope at anchor
to the southeastward of ITAN Island in
Mizara's Bank. She was identified to be (DD)
a large AK; raked bow, flush decker, goalpost
with top mast, main post, composit superstructure,
main post, goalpost with top mast.

Damage: Ship sunk.

Damage Deter- Saw one hit, which caused tremendous explosion
mined by: engulfing target in smoke. As smoke cleared
away target was seen to roll over on her stbd
side, sink by the stern leaving only a very
small portion of the bow visible. This clin-
ing to the reef.

Target Draft: 20 feet Target Anchored Range: 3300 Yds.

OWN SHIP'S DATA

Speed: 3 knots Course: 226 T. Depth: 60 Angle: 0

FIRE CONTROL AND TORPEDO DATA

This was another attack at an anchored target
protected behind a reef anchorage. Radar ranges
were used to good advantage prior to shooting.
Torpedoes were sent out on zero gyro. The
swells running were too great for a torpedo set
at 3 feet and it broached. However the next
torpedo set at 5 feet ran nicely down the range.

December 1, 1944 Let. 11-20-30(N).
Lon. 109-25(E).

TARGET DATA

Description: Two (2) DF type escort vessels on patrol duty
northeast of Camranh Bay. Contact was made by
SJ radar. There were heavy seas and wind force
6 from north. Visibility about 2000 yards.

Results: Two (2) steam torpedoes missed target (target
zig-zag during firing).
Four (4) electric torpedoes missed target (Set
at 6 feet because of heavy seas and probably
passed under target (Set up good).

Target Draft: 6 feet Course: 030°(Bow Shot) Range: 1800 Yd.(Bow)
330°(Stern Shot) 1250 Yd.(Stern)

OWN SHIP'S DATA

Speed: 10 Kts(Bow) Course: 180 T. On Surface Rough Seas.
14 Kts(Stern) 070 T.

FIRE CONTROL AND TORPEDO DATA

The 'set up' was as good as could be expected
under the circumstances of sea and wind. Torp-
edoes were purposely set at 10 feet (steam)
6 feet (electric) to prevent broaching. The
target was of too shallow draft to permit hit-
ting.

I. NO ITEMS ENCOUNTERED.

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS.
    Outside Tamranh Bay there was a continuous daylight
    patrol boat stationed. He would operate out to about the 50
    fathom curve. His action seemed just to "pin" at random.
    Also there was a continuous daylight plane patrol off Tamranh
    Bay and Cape Varella, Indo Chine. This plane patrol would
    screen all shipping passing through the area.

    Evasion tactics from the patrol boats was merely run-
    ning quiet whenever they were close. The rough weather during
    the patrol gave good surface disturbance so it was not hard
    to remain undetected from plane.

K. NO MAJOR DEFECTS OR DAMAGE.

- 34 -

— page 169 —
I. RADIO.
Reception of WXPO Fox broadcasts was normal except
for one period from 1900 to 2100 zebra when Radio Perth could
not be heard at all on any of the four frequencies. All ship
to shore transmissions were accomplished with no difficulty.
Communication on the area frequency, 2760 Kcs., was good,
both for voice and CW with the exception of strong interfer-
ence from Japanese stations on the same frequency between 1500
and 2100 zebra. Transmissions from other submarines could be
heard 600 miles away.

II. RADAR.
The SJ-1 Radar operated normally throughout the patrol
except for one major breakdown. Good ranges were obtained
on all types of vessels and land. A small sailboat was track-
ed out to 7,000 yards. The SJ-1 Radar worked effectively as
a means of communications and identification with other sub-
marines when passing through their areas. It was used fre-
quently and efficiently to communicate with the U.S. "CLOUDR"
for wolf pack communications.
On the nights of November 29th and 30th off Cape
Varalla, three contacts were made at 16,000, 17,000, and
17,000 yards. They were tracked into 5,000 yards and then
disappeared. It was a bright moonlit night but no objects
were seen. The nearest land was 43,000 yards behind the con-
tacts. The echoes were faint but reasonably well defined.
Their true speed and bearings indicated very little progress through
the water. Their intermittent character led to the conclusion
that they were an example of "ghost echoes" frequently reported
in these waters.
The major breakdown was the failure of the high volt-
age variac in the Control Unit and the high voltage transform-
er in the High Voltage Rectifier. Since their replacements
were tender spares, the use of the Radar throughout the remainder
of the patrol was due to the cooperation of the U.S.S. "BRILL"
who transferred these parts, well packed in a watertight con-
tainer, to us.
The SD-4 Radar operated normally throughout the patrol
with good ranges on both plane and land targets except for a
peculiar type of interference in the South China Sea which
blocked out the sweep for short periods. After initial deep
dive at the start of the patrol, the SD-4 Radar mast was
grounded out. At Darwin, the transmission lines were removed
from the mast and two insulators were found to have slipped.
Those insulators were replaced, the mast thoroughly cleaned,
and re-sealed. Operation was thereafter satisfactory. These
repairs were made by the U.S.S. "CHAMICIA".

— page 170 —
N. SOUND GEAR AND SOUND CONDITIONS.

Good sound conditions prevailed throughout the area.
Echo ran in and screws of patrol craft could be heard before
their masts appeared over the horizon. Screws could be heard
before they could be heard with the CA System.
During an approach on a large convoy with six escorts, each
escort was using a different frequency for echo ranging, vary-
ing between 14 and 19 Kcs.

O. DENSITY LAYERS.

In the South China Sea area, there was always an
isothermal layer from the surface to 100 feet. Off the western
edge of Dangerous Ground, there was an isothermal layer from
the surface to 200 feet. Below 200 feet there was a slight
negative gradient with a temperature drop of one degree in
the next 100 feet. Off the coast of Indo China, between Cape
Varella and Camranh Bay, there was an isothermal layer down
to 150 feet below which there was a varying negative gradient.
This gradient was usually of one degree between 150 feet and
300 feet. On November 26th, in latitude 12-35.4 N., longitude
109-58 E., there was the same isothermal layer down to 150
feet, below which there was a four degree temperature drop down
to 200 feet.

P. HEALTH HABITABILITY.

This is the fourth run for most of the officers and
crew. The major portion of the patrol was spent submerged in
close waters. Considering the above facts, the health of all
hands is considered excellent.

Q. PERSONNEL.

Throughout the patrol the officers and crew showed a
real enthusiasm to engage the enemy. During attacks and
subsequent evasive maneuvers, all hands conducted themselves
in a manner in keeping with the traditions of the Navy.

(a) Number of men on board during patrol - 76
(b) Number of men qualified at start of
    patrol - 56
(c) Number of men qualified at end of
    patrol - 63

H. RADAR COUNTER-MEASURES.

From December 11, 1944 to December 15, 1944 while
patrolling off Camranh Bay an enemy radar of 195 to 205
megacycles frequency was detected on the APR-1. It's normal
pulse rate appeared to be 1175 cycles per second with a pulse
width of about 12.5 microseconds.
On the night of December 11th the interference appear-
ed at regular three minute intervals. The pattern observed
on our APR-1 detector indicated two minor lobes on either side
of the major lobe, each separated by 15 seconds. Then our
range had decreased to 14,000 yards from the bay the pattern
on our detector screen suddenly steadied at maximum indicat-
ion just before he had contacted us. We trained on him for approximate-
ly two minutes before continuing his sweep. The regular three
minute sweep was not resumed from that time on but assumed a
very erratic, though slow, character. When our range was
14,000 yards or less he invariably beamed on us from 2 to 3
minutes before continuing his sweep.
At 1400 GOT December 16th this radar station appeared
to break down, as indicated by a sudden flash on our APR-1
detector screen and the complete disappearance of the inter-
ference until 1620 GOT December 16th when the interference
again reappeared in a very distorted pattern. Immediately
it appeared that the set was being tuned. During this process
the pulse width varied from 22.5 microseconds, low amplitude,
to 7.5 microseconds, high amplitude, and the pulse rate fre-
quency varied from 300 to 1500 c.p.s. respectively. The
final adjustment made on this enemy radar installation estab-
lished a pulse width of 12.5 microseconds and 1175 c.p.s.
pulse rate frequency, apparently the equipments optimum
operating condition.
A similar but weaker type of interference was encounter-
ed on the night of December 22 while passing through Lombok
Strait. At no time did the radar seem to beam on us. It had
a sweep rate that varied between two and five minutes with no
regularity.
The SD radar interference shows up on the APR-1 from
112 to 120 megacycles. The pulse rate is 60 and the pulse
width is about 4 microseconds. A very steady square type
wave is shown on the screen.
The interference from the SJ radar appeared at 215 and
265 megacycles as a low highly peaked pulse.
At 76 to 78 megacycles there was a constant high
noise level from some source on the boat. This was present
during the entire run. The pulse rate varied from about 250
to 400 cycles per second. The scope showed only random noise
of varying amplitudes.

U. RADIO AND RADAR COUNTER-MEASURES.

S. D. RADAR INTERFERENCE

TYPE ONE:
Closely spaced railings modulated on top, appear on
the sweep, merge, appear and disappear in about two seconds.
These series of pulses of interference move across the sweep
generally from right to left indicating some type of sweep
type radar interference. This type of interference has been
present every patrol. It is presumed to be land based Japan-
ese radar of a low frequency.

TYPE TWO:
The sweep on the SD radar screen suddenly appears
to saturate; i.e. the grass on the sweep disappears leaving
only a straight line slightly bent downward at the left.
Strong land echoes appear as oscillations on the sweep.
This type of interference was first noticed in the
Macassar Straits preceding contacts on two occasions.
No indication appeared on the APR-1 on these two occasions
nor at any other time when this phenomena was encountered.
The blocking occurs at no definite rate nor under any special
conditions. It lasts from one second to twenty minutes.
Subsequent to the Macassar Straits contacts it was noted in
the middle of the China Sea in both clear and foul weather
which tends to lend doubt to the conclusion that it is air-
borne. Nothing aboard ship could be found which might in
any way possibly give this intermittent condition; therefore,
the blocking was tentatively ascribed to climatic conditions
or enemy equipment.

TYPE THREE:
What appeared to be random noise effectively blocked
SD reception on two separate occasions.
On the first occasion a high noise level about five
megacycles wide was present at 114 and 152 megacycles on the
APR-1. The sweep on the SD jumped constantly and noise block-
ed all reception. A plane was contacted on the SD five
minutes after the interference had stopped.
On the second occasion the high noise levels on the
APR-1 were at 40 and 160 megacycles. This was present during
a heavy storm and was probably due to climatic disturbances.

FIRST ENDORSEMENT to
U.S.S. GUAVINA - Report of
Fourth War Patrol.

SUBMARINE SQUADRON EIGHTEEN
by
Care of Fleet Post Office,
San Francisco, California,
28 December 1944.

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. GUAVINA (SS362) - Report of War Patrol No. Four.

     1. The fourth war patrol of the GUAVINA was conducted in the South
China Sea. It lasted for a period of sixty-two (62) days of which thirty-eight
(38) days were spent in her assigned areas.

     2. Area coverage was excellent, resulting in five torpedo attacks
four of which were developed into costly losses to the enemy. The results were
as follows:

     Attack No. 1 was delivered against a medium AP which was
thought to be on fire. Three torpedoes were fired singly at ranges
of 1950 and 1400 yards one of them performed erratically and missed while the
other two found their mark. Subsequently the ship was observed to break in two
parts and sink.

     Attack No. 2 was made submerged against an AO anchored inside a reef. By
skillfully choosing an attack position GUAVINA was able to fire two torpedoes over
the reef from ranges of 3400 and 2650 yards both of which hit and disposed of an-
other enemy ship.

     Attack No. 3 was executed against an AK in a reef protected anchorage which
again called upon the tactical skill of the approach officer to find the proper
track for the three torpedoes which were fired against this ship. The first two
torpedoes were observed to miss however the third one cleared the breakers at the
end of the reef and struck the projecting stern of the enemy AK. It was then ob-
served to roll over on its starboard side and sink.

     Attack No. 4. An escorted medium AK was contacted and attacked during the
afternoon of 28 November. Three torpedoes were fired with a depth setting of 4
feet. Two timed hits were heard which were followed by a loud explosion and the
breaking up noises of a sinking ship.

     Attack No. 5 occurred in the early morning of 18 December against two
patrolling DE's. Two air torpedoes fired from the forward tubes missed because
of a zig at the instant of firing. Four electric torpedoes fired from the stern
tubes also missed probably because of the 8 foot depth setting imposed by the
heavy seas prevailing at the time of the attack.

Subject: U.S.S. GUAVINA (SS362) - Report of Fourth War
Patrol - Comment on.

1. The Fourth War Patrol of the GUAVINA was conducted
in the SOUTH CHINA SEA in the vicinity of TIZARD BANK and off the
coast of INDO-CHINA.

2. The first three attacks were unusual in that in each
case the target speed was zero. The tonnage on the first sinking
is shared with our Air Forces because their attacks had previously
set the ship afire and stopped it. The second and third attacks
are particularly noteworthy for skillful submerged piloting in
confined waters. Five hits were made out of eight torpedoes fired
on these targets and all three ships were observed to sink. The
fourth attack was successfully executed upon an escorted medium AK
which was hugging the coast of INDO-CHINA. Continuous periscope
bearings were used during firing, and this procedure proved itself
most effective, producing two hits out of three torpedoes fired
from a range of 1,200 yards.

3. The fifth attack was made in heavy seas against a
target identified as a DE. The Commanding Officer chose to set the
torpedoes at ten and eight feet because he considered such depth
setting to offer him his chance of having the torpedoes run
properly and hit in the sea conditions existing. No hits resulted.

4. GUAVINA performed important reconnaissance duty on
station off CAMRANH BAY from 11 December to 18 December.

5. The award of the Submarine Combat Insignia is
authorized for this patrol.

6. The Task Force Commander congratulates the
Commanding Officer, Officers and Crew of the GUAVINA for this well
conducted successful patrol during which the following damage was
inflicted upon the enemy:

Subject : U.S.S. GUAVINA (SS 362) - Report of Fifth War Patrol.

1. The fifth war patrol of the GUAVINA was the first for the
new commanding officer as such. The patrol was of 41 days duration, 26 of
which were spent in the assigned area.

2. This patrol was characterized by outstanding aggressiveness and
nice coordinated attack work with the PALMITO. The aggressive manner in
which GUAVINA patrolled close inshore along the Indo-China coast is praise-
worthy. In that area, it is very close to the coast that the targets are to
be found.

3. Six contacts worthy of torpedoes were made. Three of these were
developed into attacks, two of which were successful and the third was frus-
trated by an escort vessel which drove GUAVINA off with gunfire. However,
excellent teamwork by the GUAVINA in drawing off escorts was of valuable
assistance to PALMITO in making an attack upon and sinking the enemy AK which
was the target both submarines attacked. Of the contacts which could not be
attacked, one convoy eluded the GUAVINA by outrunning the pace between HONMAI
Island and the mainland; the same convoy returned southward 16 hours later the same day, and
who was attempting to reach attack position off HONMAI Point,
passed out of reach in shallow water by following the contour of PHUQUOC BAY
close to the beach.

4. Attacks:

(a) Attack No. 1. GUAVINA attained contact position on this convoy by
using contact reports furnished by PALMITO. The convoy consisted of
a large AO(HC) and a medium AK(EU) escorted by a TD and a PC boat.
The submerged attack was made by periscope in bright moonlight. Six torpedoes
were fired, three each at the AO and AK as they were presenting an over-
lapping target. Two hits in the tanker were observed and she was soon to
commence sinking rapidly. One timed hit was heard in the AK but was
[UNCLEAR: not] stopped. Results of this hit could not be observed as the AK was
obscured by smoke from the tanker explosion which did not clear up before
GUAVINA was forced down by an escort. Later on heavy screws were heard
to start up again. It is believed that on this attack GUAVINA sank one
large AO(HC) and damaged one medium AK(EU). To evade the escorts GUAVINA

headed for a spot near the sunken AK and bottomed in 140 feet of water.
These tactics were successful. The escorts conducted a search both by
pinging and listening and apparently failed to get contact as no depth
charges were dropped.

(b) Attack No. 2. This convoy was contacted by sighting smoke beyond the
horizon. GUAVINA went to full speed to PAMPANITO and followed it up
with excellent amplifying reports as she closed to attack. The convoy
consisted of one AK escorted by two DD's. When GUAVINA was 3100 yards
from the AK making a night, surface attack she was sighted by an escort
who opened fire on her. GUAVINA withdrew on the surface amid a rain of
projectiles, which fortunately were overs in range. With the escort in
pursuit, GUAVINA fired one electric torpedo which missed in a down the
throat shot at the pursuing escort. PAMPANITO guided by GUAVINA's reports
made contact and conducted two attacks on the AK, the second of which
was successful in sinking the AK. GUAVINA aided PAMPANITO's second
attack by firing rockets with her "Buck Rogers" gun to draw off the es-
cort. This is one successful and is a splendid example of teamwork in
coordinated attack.

(c) Attack No. 3. While patrolling submerged close inshore off Cape
Padaran, GUAVINA sighted a convoy of one large AK(EC), one medium AK(EC),
with three or four torpedo vessels or FUBUKI DD's as escorts. In an excellently
conducted periscope attack GUAVINA fired four torpedoes at the large
AK. One hit was observed in tanker's stern and two more correctly timed
hits were heard. GUAVINA was forced down by an escort, closing fast
from a range of 300 yards, and bottomed in 130 feet of water. During the
next seven hours the enemy anti-submarine forces dropped a total of 98
depth charges and bombs on her causing minor damage. After this trying
experience, GUAVINA returned to periscope depth and had the pleasure of
seeing the tanker she had hit dead in the water enveloped in flames and
a total loss to the Japs.

4. On 1 March, while clearing coast, GUAVINA was cruising at 80
foot making 2/3 speed when she received two "pretty close" depth bombs. This
incident demonstrates the danger in cruising at depths where detection by air-
craft is possible. When going below periscope depth, a submarine should go
to sufficient depth to make detection by aircraft impossible under existing
conditions of sea, light and clearness of the water.

5. Whether or not to employ bottoming in shallow water as an
evasion tactic is a matter that must be decided by the commanding officer on
the spot. GUAVINA practiced this method on two occasions, on one of which
evasion was successful but on the other of which she received a prolonged

         Patrol - Comment on.

1. The Fifth War Patrol of the GUAVINA, under the command
of Commander R. H. LOCKWOOD, U.S.N., was conducted in the SOUTH CHINA
SEA, and was the First Patrol for the Commanding Officer, as such.

2. On 6 and 7 February GUAVINA joined up with PAMPANITO to
execute a series of very effective coordinated attacks on a convoy
which was contacted by PAMPANITO during the afternoon of 6 February.
GUAVINA was coached on and made her attack submerged in the moonlight
at 0339. She fired six torpedoes and scored two hits which sank an
AK, and one more hit which damaged an AK. Depth of water 120 feet.
The same evening, 7 February, GUAVINA sighted a convoy and coached
PAMPANITO into contact. In the following attacks, GUAVINA was driven
off by gunfire at 2047, and missed a pursuing escort with one torpedo
fired down-the-throat. At 2325 GUAVINA fired four (4) pyrotechnic
rockets to distract the attention of the escorts, and as a result of
the ensuing confusion PAMPANITO was successful in executing her attack
and sinking one target. On 20 February GUAVINA executed a splendid
attack upon a convoy very close in to CAPE PADARAN. He had chosen a
position for the day's patrol which prevented any traffic from getting
by, depth of water 120 feet.

3. In two cases the GUAVINA successfully executed the un-
usual evasive maneuver of lying on the bottom. On 7 February she de-
liberately bottomed near the stern of her sunken ship, and the es-
corts failed to make contact. On 20 February she deliberately bot-
tomed in 130 feet of water and experienced a very severe seven (7)
hour counter-attack which inflicted minor damage.

4. The award of the Submarine Combat Insignia is authorized

FIRST ENDORSEMENT to

Conf. ltr. SS362/A16-3,
Ser. 04 of 8 May 1945.

From : The Commander Submarine Division FORTY-THREE.

Number Six - Comments on.

1. The Sixth War Patrol of the U.S.S. GUAVINA was
conducted in the South China Sea off CAMRANH BAY during the
period 21 March to 8 May 1945. Twenty-nine days were spent
in the area, fourteen submerged. The GUAVINA was in a pack
including the ROCK and COBIA.

2. This patrol was characterized by: rescue of
five aviators from a B-25, contacts with one convoy and 2
hospital ships, 42 aircraft contacts, many sail-boats, a great
deal of enemy radar activity and radar equipped planes.

3. The rescue of the five aviators on 28 March 1945
was a splendid piece of work. The sea was condition 4 to 5.
Plans for ditching and rescue were discussed over the VHF.
The pilot of the B-25 did a masterful job of landing. The
plane sank in two minutes. Of the six occupants, five were
rescued.

4. It is unfortunate that the GUAVINA was not able
to attain a favorable firing position on the convoy encountered
on 27 March. The convoy consisted of 2 MARUS and 7 to 9 DEs
with air cover. In attempting to close the MARU's, the sub-
marine was detected and offensive action made impossible.

5. The GUAVINA arrived at Pearl in good material
condition, clean and ship-shape. Nearly all submarines re-
turning from patrol are clean, but it is considered that the
GUAVINA was above average. She now goes to West Coast over-
haul.
