Description Convoy consisted of one extremely large tanker and
two destroyer escorts. Contact was made by SJ Radar
at 22,000 yards. Base course was 280 T, speed 8
knots, zigzagging 30 degrees right and left of base
course. Moon was rising but overhead and to west-
ward, sky was overcast.

Ships Sunk None

Ships Damaged 1 - Large tanker, 15,000 tons, 600 feet long (EU).
(Both C.O. COD and myself agreed this tanker at least
15,000 tons).

Damage Deter- Heard one hit in tanker timed for fifth torpedo fired.
mined By Unable to see because of engine smoke. Immediately
after hit, target turned on a red-over-white masthead
light and fired a white flare.

Target draft - 30 ft. Course 300 T, Speed 8, Range 4200 yards.

Own Ship Data

Speed 5 knots Course 050 T Depth - Surface Angle - 0

Fire Control and Torpedo Data

Type Attack A night surface attack with SJ radar tracking, using
TBT bearings when targets are visible.
Fired six torpedoes at 4200 yards range because port
escort headed at us at 2500 yards range. Believe TDC
solution to be very good but misses were found to be
caused by 1½ degrees lost motion in forward TBT caused
by binding of shaft in packing gland.

U.S.S. RAY Torpedo Attack No. 2 Patrol No. 6
Time 0510(H) 7 October 1944 Lat. 13-02 N., Long. 119-49 E.

Target Data - Damage Inflicted

Description Same convoy as Attack No. 1. Bright moonlight now.
Ships Sunk None
Ships Damaged Same as Attack No. 1.

Damage Deter- Heard three explosions that sounded like torpedo hits
mined By commencing 4 minutes 10 seconds after firing. Although
this time does not correspond to the generated torpedo
run, it is possible range was in error. It is believed
that some damage was inflicted in this attack because
when the COD last saw the tanker proceeding to BUSUANGA
ISLAND to anchor, it had a heavy port list, was low in
the water, and was smoking heavily, yet when we fired
he could be plainly seen to be normal in every respect
and not burning or smoking.

Target draft - 30 ft. Course 175 T, Speed 10, Range 3500 yards.

Own Ship Data

Speed 4 knots Course 270 T Depth 60 feet Angle - 0

Fire Control and Torpedo Data

Type Attack Night submerged attack at radar depth to 5000 yards,
and then at periscope depth. Bright moonlight.

Target Data - Damage Inflicted

Description Targets were two small diesel tankers, steaming in
            line of bearing 1000 yards apart, part of convoy at-
            tacked by BLACKFIN an hour earlier. Remnants consisted
            of 4 such tankers, and 4 escorts which could be seen.
            Convoy was very spread out because of BLACKFIN attack
            and after having recovered survivors. These two tankers
            were standing north together towards CAPE CALAVITE. A
            destroyer escort was accompanying them but lagged astern
            patrolling between them and BLACKFIN. The remainder of
            convoy remained about 6 miles to southward apparently
            recovering survivors. Two escorts were still working
            over BLACKFIN.

Ships Sunk 2 small tankers, 2500 tons (EC). (Sketch accompanies
            inasmuch as no CNI publication contains this type).

Damage Deter- Commanding Officer saw first tanker blow up after being
mined by    hit by 2 torpedoes, one two-thirds way aft, one in the
            bow. One timed hit in second tanker which was 1000 yds
            on far beam of first tanker and a perfect set-up for
            third torpedo in spread. Hit was followed by explosion
            similar to blowing up of first target. Sound heard screws
            of both targets stop when torpedoes hit, plus breaking up
            noises in direction of first target. Screws of escort
            coming in from southward on starboard beam were contin-
            ually heard, whereas targets screws on port quarter were
            never heard again although they were plain and loud at
            time of stopping. Depth charging did not commence until
            four and one half minutes after the third hit. Third
            hit was definitely a torpedo in direction of second
            target, 120 degrees right in bearing from escort and re-
            mainder of convoy.
            One hour and twenty minutes after firing came to per-
            iscope depth and could see only two escorts in vicinity
            of attack 8000 yds. away.
            Large patches of light oil or gasoline were sighted that
            night when passing through spot of attack.

Target Data - Damage Inflicted

Description Target was large transport, stopped and on fire, with
            two escorts patrolling vicinity. Believe he was part
            of convoy sighted earlier this afternoon which had
            apparently anchored in DASOL BAY for night. He was
            burning furiously throughout his superstructure and
            cabin space amidships, but hull was intact. I am
            positive he was not torpedoed. At first I believed he
            had been set afire by bombing, but after thinking it
            over believe his fire was started internally or at most
            by a strafing attack, because his masts, goal posts,
            superstructure and antennas, ventillators, such as life boats, radio
            fittings, partition pipes, etc. were all in place and
            undamaged except that being caused by fire. The ship had
            not been completely abandoned because fire fighting
            parties were seen on deck. We fired two torpedoes at
            2800 yards when we were apparently seen by the target
            and he commenced signalling to the escorts for help.
            Escorts were patrolling 8 to 10 thousand yards from
            target.

Ships Sunk 1 Large AP, 8592 tons (LC) GOSYU MARU type, CNI-208J,

Damage Deter- Commanding Officer and entire bridge watch saw ship
minted By sink in 3 minutes after first torpedo hit blew the
            bow off and second hit in MOT started her down with
            a 45 degree angle.

Time 0946(H) 6 November 1944 Lat. 16-08 N., Long. 119-43 E.

Target Data - Damage Inflicted

Description Target was MOGAMI CLASS heavy cruiser, the first of
two heavies leading a convoy consisting of 2 cruisers,
1 tanker, 5 escorts, and possibly more.
Convoy was conforming to coast line and being about
12 miles off beach. We easily got inside escorts. In-
asmuch as it was glassy calm ran at 120 ft. inbetween
looks to avoid detection by plane cover which consisted
of 2 to 4 float planes. At range 1000 from target, com-
menced matching gyros forward for what appeared to be the
"Kill" of our submarine careers. (Torpedo run 800 yards
set up in TDC periscope depth, gyros 40 R, 30 to 35 P tracks,
speed 10, 6 torpedoes) At this time sound reported
torpedoes 140 relative and target turned left to avoid.
Torpedo tracks straddled us as cruiser was seen to pass
unharmed 450 yards down our starboard side. Second
cruiser also seen to pass. Both speeded up to 15
knots, their wakes could be seen boiling as they in-
creased speed.
When torpedoes had passed cruisers made zig to right to
clear destroyer escort which was now depth charging
submarine that fired (RATON). With MOGAMI steady, fired
4 electrics aft on 160 S track, torpedo run 3000 yards,
speed 15, spread 800 feet. One minute after firing
bombs dropped all around us, so went deep. Before
ducking another set-up was put in TDC and was found to
be right on in bearing and 20 yards out in range.

Ships Damaged 1 MOGAMI CLASS CRUISER, 14,000 tons (estimated tonnage
from ONI-41-42.)

Damage Deter- Cruiser seen to be undamaged at time of firing. Although
mined By bombs and depth charges were heard prior to and during
firing, everything became quiet between 2 and 3 minutes
after firing and at precisely 3 M 07 S after firing,
the torpedo run, the first hit was heard. At 3M 26S,
the second hit was heard, corresponding to a run for the
third torpedo, followed by a heavy explosion. At this
time sound reported targets screws to stop and breaking
up noise. I ridiculed this information, because I did not
believe two hits would stop or sink this vessel.
Fifty-five minutes later at periscope depth observed
cruiser 7000 yards away dead in water with bow blown off
forward of No. 2 turret. Inasmuch as no explosions were
heard from time of our hits and this observation, I am

positive our torpedoes inflicted the damage observed.
A very reasonable explanation from data available is
that first torpedo hit him in stern on 160 S track,
damaging screws and rudder, second torpedo missed
astern, third torpedo hit him in bow blowing up No. 1
turret, fourth also missed astern. Sound did hear
the screws stop and the breaking up noises were caused
by his bow sinking.
The story of our attempts for kill is contained in
the narrative, and although unsuccessful, we were
further able to verify this damage at 1000 yards
when coming to periscope depth after our grounding.

Target Data - Damage Inflicted

Description Target was second of 3 large AK-AP's in convoy with
4 or 5 escorts. While conducting coordinated search
with RAY and BATFISH, RATON reported being in contact
at 1620(H). BATFISH reported being in contact about
1800(H). RAY made contact at 2000(H) on port bow of
convoy. RATON was tracking on starboard bow and BATFISH
on port bow. At 2033(H) a zig placed RATON and BATFISH
both on starboard bow, so closed for attack, informing
other boats of my action. Night was black. A large
heavy ship was selected as our target, placed the second ship 2000 yards closer
to us, shifted to him. Got inside escorts and fired 6
torpedoes, divided fire being inadvisable and wishing
to be sure of sinking one, rather damaging two ships.

Ships Sunk 1 Large AK, 7500 tons (EU). Ship had large center
island super structure. Appeared very similar to our
LIBERTY SHIPS. Gasoline loaded.

Ships Damaged 1 Escort (SMC), 1500 tons (EU).

Sunk

Damage Deter- Commanding Officer and entire bridge watch observed
mined By four perfect hits which completely disintegrated target
with violent explosions that illuminated scene like day-
light thereby forcing us to dive to escape detection and
gunfire. On way down a fifth hit was heard in another
ship 1500 yards on other side of target. JOOD sighted
an escort on far side and about 4 degrees to right of
target, just prior to diving. Fifth hit was probably
in him.

Target Data - Damage Inflicted

Description Target was a medium AP that had apparently been bombed
and beached on a reef in VIGAN ANCHORAGE. Inasmuch as
he was quite worth salvaging, decided to give him one
or two torpedoes. Did not consider it wise to close
inside of 4000 yards because of shallow water (10 fathoms)
and possibility of mines. Fired one which was seen to
miss to the right, then fired a second off set by amount
first one missed. Second torpedo missed. Currents
from four rivers emptying 2 miles north of target caused
torpedoes to miss.

War Patrol Report.

Subject: U.S.S. RAY - report of SIXTH War Patrol.

1. The SIXTH war patrol of the U.S.S. RAY conducted in the SOUTH
CHINA SEA area was of 72 days duration, 44 of which were spent in the assigned
area. During this patrol the RAY formed a coordinated attack group with the
COD and later with the LION and LAPIER. In addition a special mission was
completed and lifeguard duties were performed resulting in the rescue of one
aviator on the 12th of October. The conning tower was flooded early in the
patrol due to failure to close the upper hatch. This necessitated a return
to LOS OLNDI for repairs. Patrol was resumed after 7 days.

2. Eleven contacts were made worthy of torpedo attack. Eight of
these were closed for attack.

TORPEDO ATTACK NO. 1 - This was a night surface attack on 6 October, made
on a large AO with two DD escorts. Six Mark 14 torpedoes were fired, 750 track,
gyros 35°, torpedo run 4200 yards. One hit was obtained. The misses were later
determined to be caused by lost motion in the TDC.

TORPEDO ATTACK No. 2 - This attack was conducted on the same target as
attack No. 1, following an end around. After a night radar approach the RAY
submerged to periscope depth and fired six Mark 14 torpedoes on a 1000 to 1050
track, gyros 15° to 20° left, torpedo run 3500 yards. Three explosions were
heard which were timed as torpedo hits. Target was later seen by the COD in
a damaged condition.

TORPEDO ATTACK No. 3 - On 12 October a day periscope attack was conducted
on a large AK escorted by two UNIDENTIFIED torpedo boats. Four Mark 14 torpe-
does were fired, 500 track, small gyros, 1200 yard torpedo run. Two hits
were obtained and the target was seen to blow up.

TORPEDO ATTACK No. 4 - On 1 November an attack was made on a convoy
consisting of one AK, four AO's, and three or four escorts. Attack was com-
menced on the large AK but during the approach it became apparent that the
target had been hit by another submarine. Approach was then shifted to the
four small tankers which conveniently turned toward. Three Mark 18 torpedoes
were fired at two overlapping tankers, 125° track, gyros 150°, torpedo run
900 yards. Two hits were obtained in the first target which blew up and an
additional hit was heard in the other tanker as the RAY went deep. The

second tanker probably sunk as hissing up noises were heard from both targets.

1. TOKYO ATTACK No. 5 - On 4 November a night surface attack was made on
a large AP which had previously been damaged by straffing or bombing. Two
Mark 14 torpedoes were fired on an 85° track, torpedo run
2800 yards, zero gyros. Both torpedoes hit and the target was seen
to sink.

TOKYO ATTACK No. 6 - On 6 November a day periscope attack was made on
a convoy consisting of two heavy cruisers, several transports, and many surface
and air escorts. Four Mark 18 torpedoes were fired at a OMAHA Class cruiser.
160° track, gyros 15°, torpedo run 3000 yards. Two hits were timed to have later
been observed the cruiser stopped with her low bow blown off. During this approach
the RAY observed torpedoes passing down her port and starboard sides, apparently
fired by the RAY. Immediately started another approach on the cruiser
but was forced deep due to bombing and the approach of two escorts. The RAY
ran off the starboard sound head. The cable
grounded in 370 feet of water, which prevented the RAY from coming to the
depth before the flow of water could be stopped. At this time the RAY was in
a beautiful position for the kill on the cruiser and also on a tanker taking
the cruiser in tow, but, wisely abandoned the attack due to the fact that she
was unable to go deep and the escorts were only 800 yards away.

TOKYO ATTACK No. 7 - On 14 November a night surface attack was made on
a convoy consisting of three AK's and four escorts. Six Mark 14 torpedoes
were fired at a medium sized AK, 90 to 95° track, torpedo run 2500 yards,
170°. Four hits were obtained in this target which blew up and sank. Another hit
was obtained in what was thought to be an escort on the far side of the AK.

TOKYO ATTACK No. 8 - On 16 November a day periscope attack was made on
a grounded AP. Two Mark 14 torpedoes were fired on an 85° track, torpedo run
4200 yards, zero gyros. The attack was abandoned as strong currents caused the
torpedoes to miss and the range could not be closed due to mine fields and
shallow water.

3. On 30 September a night gun attack was attempted on a large two
masted sail boat, but was abandoned after casualties to both 20MM guns.

4. The RAY returned from the patrol in fair material condition,
clean, and in a fine state of morale. The RAY will be returned to West Coast
yard for overhaul.

5. Fire control performance of this ship is excellent. Eighteen
hits were obtained out of 33 torpedoes fired.

1. The sixth war patrol of the RAY was conducted in the
Makassar Straits -- Sulu Sea -- Mindoro Straits -- South China Sea
west of Luzon, areas. During the first phase of the patrol the RAY
coordinated with the U.S.S. COD (SS224). During part of the second
phase, after replenishing torpedoes and conducting a minor refit at
Mios Woendi, she joined with the RATON and BATFISH. The RAY also
conducted a special mission during this patrol which was the subject
of a separate report to Commander Submarines, Seventh Fleet.

2. This long, aggressive, heads-up patrol resulted in
eight torpedo attacks, all of which were expertly planned and execu-
ted. The results are best indicated by the great damage inflicted
upon the enemy. The RAY also had the privilege of rescuing a down
friendly aviator off the west coast of Luzon.

3. Award of the Submarine Combat Insignia is authorized
for this patrol.

4. The Commander Submarine Force, Pacific Fleet, congratu-
lates the commanding officer, officers, and crew for this outstanding
patrol which is in keeping with the well established fighting record
of the RAY. During her six patrols the RAY has sunk 20½ ships for
146,206 tons and damaged 7 for 54,727 tons. During this patrol she is

(A) PROLOGUE:

Arrived PEARL HARBOR from sixth war patrol on 8 December
1944. Departed for MARE ISLAND on 10 December
1944. Arrived 16 December 1944 and commenced major overhaul
on 17 December 1944.

The overhaul consisted of the routine work performed on
all submarines plus the accomplishment of all uncompleted
alterations. Those alterations most worthy of mention are:

(1) Elongation of conning tower with resultant re-
    arrangement of interior.
(2) Moving SD mast aft of conning tower, and SJ mast
    aft of periscope shears.
(3) Installation of hydraulic periscope hoists.
(4) Installation of ST periscope and radar.
(5) Installation of DCDI.
(6) Installation of TBT.
(7) Installation of 5" and 40 MM guns.

Departed NAVY YARD, MARE ISLAND on 19 March 1945, and
arrived PEARL HARBOR on 26 March 1945. Had ten days of
very beneficial training with Comsubdiv 43, COMMANDER R. S.
BENSON, U.S. NAVY, as training officer, during which six-
teen exercise torpedoes were fired and battle surface firing
was conducted against both towed and anchored targets.

The SUBMARINE BASE, PEARL HARBOR performed voyage repairs
and accomplished the latest alterations. Those worthy of
mention are:

(1) Installation of additional radio receiver.
(2) Installation of TDM and TVG.
(3) Installation of whip and wing antennas.
(4) Installation of LORAN equipment.
(5) Installation of second 40 MM gun.

The readiness for sea date was delayed because of cas-
ualties to the stern planes and because of the damage re-
sulting from a hit by a MK 23 exercise torpedo.

On 19 April 1945 departed PEARL HARBOR for GUAM, arriv-
ing 29 April 1945. The U.S.S. HOLLAND performed post-
voyage repairs.

1346 Could see tops of 3 small coastal freighter type
     vessels, which turned out to be a hunter-killer
     group. They are opening out to northward and
     we aren't going to get at them.
1507 While getting ready to surface for end-around,
     sighted mast closing under smoke of targets,
     to find a convoy of 3 sea trucks heading south-
     east. (Ship contact #11).
1550 Surfaced. Commenced chase on our three smokers at
     18 knots. Sea trucks appear to be quite suitable
     targets, so decided to use 5" gun in passing
     while chasing smokers.

     This turned out to be the poor policy of trying to
     do two things at once. As a result only one sea
     truck was destroyed, using an excessive amount of
     5" ammunition. Furthermore we passed up several
     gun targets for what ultimately proved to be
     neither suitable for gun nor torpedoes.
1602 Commenced gun attack #1 at range 3,900 yds. Sea
     truck formation firing back with .30 cal. or .50
     cal., none close.
1612 Ceased firing after serveral hits left the target
     burning furiously from bow to stern. Target was a
     large diesel sea truck of about 400 tons. He was
     leader and one of two about twice as big as the
     remaining 200 ton jobs. All sea trucks now head-
     ing for coast with 180° angle. Secured guns and
     continued chase.
1630 Smokers now heading our way with sharp angle. Can
     see masts from bridge. This looks fishy, but
1635 Submerged and commenced approach. Manned battle
     stations.
1715 Target now plainly visible. They are three patrol-
     type trawlers of about 800 tons. They are travel-
     ling just outside the 10 fathom curve in a line of
     bearing about 2,000 yds. apart. They are obviously
     "sucker bait" and in the "good old days" we
     wouldn't have looked twice at them, but it has been
     a long time since we've heard a torpedo go off so
     chose one to seaward as our target.
1724 Fired 3 torpedoes from bow tubes on 70° S T.
     R gyro 2,500 yds. torpedo run, spread 300 ft. for
     150% coverage. Depth set 4 ft. Sound tracked

     torpedoes on bearing of target for proper torpedo
     run. No hits. At
1728 Set-up still checks perfect in TDC. Can only be-
     lieve they either ran under target or slower than
     set.
1729 Center trawler now headed across bow of target,
     pouring black smoke and flying a signal on yard-
     arm. We have been detected. Swinging left to
     bring stern tubes to bear.
1731 Both trawlers heading at us with about 100 S.T.
     angles. Range 1,200 yds. Three depth charges
     Decided to go "deep" (150 ft.) and rig for depth
     charge.
1744 After stopping to listen, one target speeded up,
     came our way and dropped three heavy "tooth-
     rattling" depth charges. These are the worst
     most of us have experienced, although the severe
     shaking-up can be attributed to the shallow depth
     of water. This is our first depth-charging at less
     than 300 ft. Paint and cork flew about madly,
     a few light-bulbs broke, but otherwise the boat
     took it in her usual fine stride.
1748 Three more in rapid succession, very close a-
     lieved astern although DCDI indicates a perfect
     straddle. Targets stayed with us but did not drop
     any more depth charges until
1807 Targets began to open out to eastward.

     Target was seen to be a small motor patrol boat of
     about 60 ft. length 25 tons. He had a collapsible
     mast which, was apparently used for rigging a port-
     able radio antenna, and he had what appeared to be
     a portable micro-phone lowered over side as a sound
     gear. There were no fishing boats in sight and he
     was obviously not engaged in fishing activities.

0823 Submerged for patrol near 10 fathom curve off

     In the thickest collection can be seen another
     small patrol boat similar to the one sunk this
     morning. He was temporarily patrolling at slow speed
     weaving in and out of sampans. Our assumption that
     he was a submarine spotter was born out when at
1016 Sighted masts of our three trawler friends of yester-
     day 281 T, 7 miles, 0 angle on the bow. (Ship con-
     tact #14). Waited to see if they would turn away
     but they kept coming at us. Am convinced patrol
     boat coached them on. Decided it would be foolish
     to take drubbing as we did yesterday, so at
1044 Battle surfaced on four main engines at flank speed
     and commenced opening out to southward - the only
     available direction. Tracked trawlers at 12 knots
     while we were making 20.8 knots. Had them broad
     on starboard quarter, so range remained constant at
     about 6,900 yds. They were firing 3" guns at us,
     but shot was falling short.

     At this point I could visualize them madly radioing
     to KEIJO for air cover, which if provided would
     embarrass us considerably. So decided to fire a
     few rounds of 5" to slow them down and allow us
     to open out to deeper water. (Gun attack #3).
1050 Commenced firing.
1059 Ceased firing. Eleven rounds of 5" ammunition
     expended and although the best we did was got two
     close shorts directly ahead of nearest trawler,
     the attack produced the desired results. The
     three trawlers turned away and allowed us to open
     range to 10,000 yds. and commenced gaining a little
     distance to the west. At
1104 Ceased firing two trawlers resumed
     chase to "save face", but we now had them astern
     and were opening range fast.

flank for schooner. As range closed, could see
she was a brand-spanking-new vessel about 150 ft.

though no flag was flown, there is no doubt that
this is a valuable cargo vessel operated by the

0903 Headed north.
Sighted another schooner 300 T, 7 miles. (Ship
contact #25).
0917 Commenced firing with 40 MM guns. (Gun attack #9).
Range 400 yds. Just fired a few rounds into rig-
ging to convince crew to abandon ship.
0924 Our tactics worked! The crew lowered the lifeboat and
abandoned ship. Maneuvered alongside to board.
0930 Moored alongside. Sent boarding party in charge of
the EXECUTIVE OFFICER. Holds were full of rice.
Seized charts, sailing directions, log, various
other unidentified papers, JAPANESE shipping company
house flags, magnetic compass, etc.

Our Chief Quartermaster GOSSETT came out of the
after hold with the master at the point of a gun.
Took him prisoner. Set fire to schooner, backed
away and unloaded the one shot in the 5", nicely
opening the "vents".
0957 Headed north. Target enveloped in flames and gett-
ing low in water.
1125 Target completely burned to water line. Target sank.
1207 Submerged.
1300 Interrogated each of the two prisoners. First
prisoner stated he was from north KOREA and was four-
th on the first schooner sunk. His ship was enroute
from DAIREN to FUKUOKA, KYUSHU with a load of rice.

Second prisoner stated he was master of the schooner
boarded and set on fire. He was from southeast KOREA
and his ship was bound from DAIREN to MOJI via FUSAN.
He explained the meanings of the flags captured.

We were not trying to beat ONI to the quiz, but
merely trying to confirm our opinions that the cargo
was going to JAPAN. We asked only
questions to obtain this information. A Chinese
book entitled "POINTIE TALKIE" given us by our
aviator friends proved very helpful.

0722 Commenced firing both 40 MMs (Gun attack #13). Crew
     got the news fast and immediately lowered all sails
     and lowered lifeboat. At this time noted two schoon-
     ers to northward heading for SHOBO TO which was only 7
     miles to northward. Farthest schooner was only
     about 2 miles off beach, so decided we'd let him go,

1002 Sighted smoke 267 T. (Ship contact #40). Went to

heading to pass close to ENCOUNTER ROCK. We have
a long tough run to intercept him, but inasmuch as
he appears to be a small freighter or possible
mine layer, we decided to try. We were later sorry
for this.
1152 Target, now seen to be a minelayer, reversed course
and headed back for PORT ARTHUR. Don't know what
his game was, but he fooled us. After running at
6 knots for over 30 minutes we got no closer than
9,000 yds. Secured from battle stations.

6 knots.
1616 Sighted large transport heading northeast (Ship

1648 Targets zigged away conforming to coast. I had
hoped they would cut straight across PORT ARTHUR
HARBOR directly for POHAI STRAIGHT, but they are
hugging coast all the way, our friend this morning
certainly drew us out of psosition. Secured from
battle stations.
1703 Sighted large tanker and medium freighter 010 T
and 050 T very close to coast. (Ship contact #43).
Do not believe we can get in on tanker, but will try
if not, we will still be in position for freighter.
Went to 80 ft. at 6 knots. Our battery getting low
from this high speed running. Went to battle stat-
ions.
1717 Shifted targets to freighter. These ships are run-
ning less than a mile off the beach. They blend
with the background so perfectly that they are not
sighted until it is usually too late for us to
effectively close the track. This freighter is
our best set-up of the day however. The surface
is choppy making it perfect for use of
ST radar. Periscope exposures average 3 seconds
and our solution is perfect. So at
1751 Commenced firing five torpedoes forward on 105 P
track, 3 R gyro, 3,000 yd. torpedo run, spread
500 ft. in hits.
1806 Angle still unchanged. Bearing and angle
on the bow right on, range 40 yds. low. I am
convinced torpedoes run much slower than set.
Secured from battle stations. Commenced tracking
hoping to catch them tonight.

this point, our dependable engine-room gang chose
2146 to flood #2 main engine and crack a liner.
SJ radar contact on our tanker 295 T, 55,000 yds.
Commenced tracking.
2215 With 1 min out of commission and a very

REMARKS:
Sound tracked torpedoes on exact bearing of target for
proper length of torpedo run. Set depth 4 ft. because of
lossy surface of water allowing a broaching torpedo to be
easily sighted and avoided. Torpedoes either ran under or
much slower than set in TDC.

TARGET DATA - DAMAGE INFLICTED

SUNK | 1 - 400 ton diesel lugger (LC). Target was
| of the tanker type about 170' long, and draft
| 8'. He was one of two which were about twice
| as big as the standard 200 ton type, which
| comprised the remainder of convoy.

DAMAGED | None

DAMAGE DETERMINED BY - Observed 3 hits, 5 near misses, which set oil
| cargo off into a fiercely burning fire which
| enveloped target from bow to stern in a matter
| of seconds. Target observed to sink about
| 1700.

DETAILS OF ACTION

Target was leader of convoy of 8 luggers. 53 rounds of 5" ammunition
were fired at average range of 3,900 yds. for 3 hits and 5 near miss-
es. This was an extravagant expenditive of ammunition, but range was
not closed more and remainder of convoy not attacked because of clos-
ing target group for torpedo attack #1. Targets returned fire with
ineffective .30 cal.

DETAILS OF ACTION

We now instituted what became a standard type attack. As the
target was closed from the quarter, about 10 rounds of 40 MM were
fired into the sails and rigging to start crews to abandon ship.
Target was then boarded, crew put in lifeboat, and then completely
set on fire using oil soaked rags ignited by very stars. Target
became quickly enveloped in flames and we then hauled out on wind-
ward side about 200 yards and fired 1 round of 5" ammunition, which
tore a huge hole at waterline amidships and 30 rounds of 40 MM, which
did likewise. Target settled quickly but took about 2 hours to comp-
letely sink.

(J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS:

     No new anti-submarine measures were encountered. On
three separate occasions a Hunter-Killer group consisting of
three trawlers was encountered in the vicinity of ISHIKI
GUNTTO. On no occasion could pinging be heard from this group.

(K) MAJOR DEFECTS AND DAMAGE:

     HULL
     1. The Garlock chevron packing installed on both periscopes
        has been completely unsatisfactory. Although both were
        repacked on numerous occasions, excessive leaking could
        not be stopped. Repeated greasing arrested the leaking
        only temporarily. The commanding officer hopes he will
        not be cursed by two such periscopes on the next patrol
        and recommends replacement with the old type flax packing
        which always was satisfactory aboard this vessel.

(K) MAJOR DEFECTS AND DAMAGE: (Continued)

MACHINERY
1. On 3 May the inner bearing of the south rotor of the 1K
   VII Arma Gyro Compass failed after 870 hours in use. It
   was replaced from spares.

2. On 2 June 1945, #2 main engine was flooded when being
   started upon surfacing. The following damage was done
   to #9 unit: broken liner, broken piston, bent connecting
   rod, damaged conrod bearing. In addition, the whip from
   the conrod broke the liner on #1 unit. The damaged parts
   were replaced from spares.

3. Operation of the Badger X-1 stills is made difficult by
   constantly changing operating conditions, especially
   changing voltage, requiring constant attention by the
   operators. On three occasions, heater elements were
   burned out by low water level. It is believed that
   installing electric tachometers such as is used on the
   trim pump would be a great help.

ORDNANCE AND GUNNERY
1. Following the attack on 19 May, torpedo #99860 was found
   to have a flooded gyro pot. Gyro was removed, dried, and
   lubricated. Torpedo was later fired with no indication
   of erratic gyro performance.

2. During normal routine on 9 June, after leaving the area,
   call #20 in torpedo #99573 was discovered to be completely
   dead. No gravity roll could be obtained. The coil was
   jumped out immediately.

3. No casualties occurred in twenty-one gun attacks in which
   815 rounds of 40 MM and 137 rounds of 5" ammunition were
   expended.

(L) RADIO:

   The SPOT whip antenna system as installed by the
   Submarine Base, Pearl Harbor prove very unsatisfactory. Dur-
   ing the first week of patrol all four whip masts sheared just
   above the angle braces because of vibration. The concentric
   conductors permitted excessive power loss in transmitting
   rendering the whip antenna practically useless. The whip
   antenna, however, was satisfactory for receiving and at times

     for area frequency transmitting. It was further found,
that when submerged at periscope depth, a following sea
would wash the antenna above the surface, requiring the
antenna to be lashed in the horizontal position at all
times.

     Substitute loop antennas were rigged between the side
stantions of the bridge and after cigarette deck life
rails, with connections to the regular antenna trunks.
This system proved excellent for both high and area
frequencies and a permanent installation will be re-
quested this coming refit.

(M) RADAR:

     The performance of SJ, ST, and SD radars was excell-
ent and left nothing to be desired. No casualties of any
note occurred.

(N) SOUND:

     On 25 May the TDM became noisy and the training motor
overheated. A chainfall was required in addition to
hydraulic power to raise the hood. Efforts to free the
spider failed and it was secured for the remainder of the
patrol. It is believed that a fishing net became fouled
around hood and spider when we went alongside a fishing
boat to discharge survivors of one of our gun attacks.

     On 27 May, it was found that the port sound hydraulic
shaft had backed two and three quarter turns out of the
hydraulic block casting, and that the azimuth circle cast-
ing had backed six turns off the main sound shaft. The
hydraulic shaft locking key was found sheared off and one
of the main shaft lock-screws was found loose and one was
found missing. The backing-off of the azimuth circle
casting had parted all leads from the head.

     The main sound shaft was clamped in the half-lowered
position, the azimuth circle casting removed, and the leads
inside the main shaft. The casting was then
replaced, locked on, and the leads re-connected. The
hydraulic shaft was tightened and relocked.

(N) SOUND: (Continued)
The exact cause of this casualty is not known, but it
is believed that caroless insortion of the lock-scrows dur-
ing navy yard overhaul finally allowed the azimuth circle
costin; to back-off, while training the hond, rosulting in
binding of hydraulic shaft, shoaring the locking key and
bcking it out the exact number of turns the hond makes in
training from one extreme to the other,

Both sound hoads and shafting should be th roughly
overhauled this coming rofit.

(0) DENSITY LYNG:
Woter temperaturos in the North Yellow Soc during the
month of Hay showed a characteristic 6 to 12 dogros negativo
gradient at depths down to 100 ft. This gradual decline was
more dofined in arocs close to lend, particularly off the
KANTUNG KONINSUL... In this are at ranges of one to five
milos fron lond at sixty foot depth en abrupt rise of tempor-
ature was oncountered several times, amounting to 10 to 12
degrocs. Average water temperatures were 56 F on the surf.co
end 44 Fct 60 fect.

(F) HEALTH, FOOD, ND H. BIT BILITY:
The health of crew was fair.

Approximately 35 non contr.cted common colds and 5
cases of mild tonsillitis occurod. Those frocuont colds
wore the result of the crot fmount of condensation and
dempnoss caused by oporesing in cold rathor. Ono men had
a slight Sulfathizol tretment reaction resuting in
swollon hands and feet accompanied by extensive skin rash.

The food was good.

It was very difficult to koop the boet up to its high
standard of cleanliness because of extensive condensation.

     The performance of officers and men during this patrol
     was up to the usual high standards.

     It was very gratifying to note that eagerness and
     interest prevailed in spite of the lack of torpedo targets
     and in spite of the failure of attacks against those en-
     countered.

     The spirit of helpfulness and unselfishness displayed
     by all hands in accommodating the twenty rescued aviators
     also afforded great pleasure to the commanding officer.

     TOLL G. L. 321 51 32, CHM(AA)(T)(SS), USN is to
     be especially commended for the excellent medical treatment
     given the wounded among the rescued aviators. The command-
     ing officer feels that his performance of duty was above
     the normal requirements of the service.

The frequency meter was used to tune the transmitter. Reception
of the Sub Fox schedule was good throughout the patrol.

No enemy jamming was experienced on the primary ship shore
frequency or the area frequency. A combination of sing-song
talking and hysterical screaming by the JAPS made communication
over the life guard frequency difficult at times, but never
impossible.

(V) REMARKS:

1. TORPEDOES

As can be seen from the attack data, the performance of
the MK 18-2 torpedoes was highly unsatisfactory and very dis-
couraging to say the least. There appears to be little doubt
that in low water temperatures such as those encountered (aver-
aging 54 F on the surface, 44 F at periscope depth) the average
speed of the MK 18 torpedo for a run greater than 2,000 yards
is considerably less than that given on the temperature-speed
curves for use on the TDC.

This theory will undoubtedly be disputed by authorities who
have made a more complete study of the characteristics of the
MK 18 torpedo, and perhaps they can find the answer to the poor
performance experienced on this patrol, but at the writing of
this report, this theory remains the only logical one in the
mind of the commanding officer. This is further substantiated by
similar if not identical experiences by other boats in this
same area, notably the JALLAO on her second patrol.

Whereas all three attacks bear out this theory of slow
torpedo speed, attack No. 2 on 2 June 1945 presents the most

conclusive evidence. The target was a 5,000 ton freighter on
a steady course. Eleven observations by periscope were made
prior to firing obtaining complete set-ups each time i.e.
bearings, range, angle-on-the-bow. All ranges were obtained by
ST radar. Five torpedoes were fired on an average track of
107°, torpedo run 3,000 yds., spread 500 ft. or 133%, depth
set 2 ft. At time of firing the torpedo was on the same
bearing as the target - no hits'. The target remained on
the same course after firing. Numerous observations were made
and the data checked perfectly with that generated by TDC. A
final set-up was obtained fifteen minutes after firing and the
bearings and angle-on-the-bow were right on with the TDC and the
range was low 40 yards. All fire control gear was checked and
nothing found wrong. Gyros were checked and matched before
firing. What else could it be but slow torpedo speed!

It can always be said that a torpedo run greater than
2,000 yards is excessive. Naturally any determined and
aggressive commanding officer will take his ship well inside
of 2,000 yards if he can, but it is frequently impossible and
torpedo runs of 2,000 yards to 3,000 yards have to be accepted.

After penetrating shallow and hazardous waters to attack
the few targets that avail themselves these days, can it be
asking too much to want dependable torpedo performance? The
commanding officer does not think so.

2. 40 MM GUNS

Two 40 MM guns are installed aboard this vessel, one on
each cigarette deck. Their performance was excellent. In 21
gun attacks, 815 rounds were fired from both guns without a
single casualty. They proved to be a very dependable and
extremely effective weapon.

Inasmuch as submarine gun action is usually against a
surface target, installation of telescopic sights with a yoke
and range - deflection scales, would make the shooting more
accurate than with the open sight. This would result in the
saving of about half the ammunition expended, that amount
being used for spotting even at short ranges.

3. MOTION PICTURES AND BROADCAST RECORDS

These two items afford the crew of the RAY more pleasure
and recreation while on patrol than anything else carried for
this purpose. In spite of this, the selection available is
very meager.

The majority of the motion pictures taken on this patrol
were third rate entertainment and usually an insult to one's
intelligence. The commanding officer believes first rate
pictures should be available for a first - rate audience.

The broadcast records available for this patrol were the
same records we have had aboard for the past two patrols, all
being recorded in 1943 and early 1944. Considerable time and
effort was expended in trying to assemble a suitable record
library for this patrol, but activities in the San Francisco
Area, Pearl, or Guam had little to offer.

The records are available however if the distribution can
be directed to those who should receive priority.

1. The Seventh War Patrol of the U.S.S. RAY was conducted in the
Yellow Sea area during the period from 30 April 1945 to 16 June 1945. Thirty-
six days were spent in the area, of which nineteen were spent submerged. From
30 May until departure from area the Commanding Officer, Commander W. T. Kinsella,
U. S. Navy coordinated the operations of all submarines in areas 9 and 12.

2. Eleven days were spent on lifeguard station at the early part of
the patrol and the RAY had the satisfaction of rescuing a total of twenty aviators.
Ten were from an Army B-29 and ten from an Naval PBM. This second rescue was a
particularly beautiful piece of work, being conducted at night in heavy seas, and
in close proximity to rocks and shoals. The coordination between search planes
and submarine was excellent. All twenty survivors were transferred to submarines
returning from patrol.

3. This patrol is characterized by excellent results with the 5" gun
and 40 mm guns, and by disappointing torpedo performance. The RAY engaged in a
total of twenty-one gun actions which resulted in the sinking of one large and two
small sea trucks, two small patrol boats and fifteen large four masted schooners.
These schooners were all new, well outfitted, and were engaged in carrying rice to
Japan. The RAY perfected a plan for the mass destruction of them by firing one or
two shots to cause them to lower sail, then going alongside to inspect the cargo
and set fire to them and finally backing clear and putting one 5" in the water
line. Two prisoners were taken from these schooners, one of which was the master.

4. All 5" and 40 mm ammunition was expended and it is noteworthy that
the RAY experienced no gun casualties in expending the entire allowance, which
speaks well for the upkeep procedures and material condition of the Gunnery De-
partment.

5. The RAY made three torpedo attacks firing Mark 18-2 torpedoes,
none of which was successful.

Subject: U.S.S. RAY (SS271) - Report of Seventh War Patrol
(30 April to 16 June 1945).

1. The seventh war patrol of the RAY, under the command of Commander
W. T. Kinsella, U.S. Navy, was conducted in the Yellow Sea areas. The RAY per-
formed lifeguard duties as well as an offensive patrol. The commanding officer of
the RAY acted as group commander for the six to eight submarines in the area
(RAY, RATON, SCABBARDFISH, BALAO, SEA CAT, SHAD, SEGUNDO, and BILLFISH) during
this patrol.

2. This patrol was another outstanding performance for the fighting
ship RAY. Two rescues, one made under the most adverse weather conditions in shoal
enemy waters, resulted in twenty friendly aviators being picked up and returned
to port. Three torpedo attacks were made; but, unfortunately, no hits were ob-
tained. A total of twenty-one well planned and expertly conducted gun attacks
were made on miscellaneous small craft, resulting in twenty small ships, ranging
from a large sea truck to small motor patrol boats and four-masted schooners en-
gaged in hauling rice to the Empire from Korea, being sent to the bottom.

3. Award of Submarine Combat Insignia for this patrol is authorized.

4. The Commander Submarine Force, Pacific Fleet, congratulates the
commanding officer, officers, and crew of the RAY for another outstanding and
highly successful patrol. The RAY is credited with having inflicted the following

(A) PROLOGUE:

        Arrived MIDWAY from seventh war patrol 16 JUNE 1945 and
        commenced normal two-week refit by U.S.S. BUSHNELL and RELIEF
        CREW SUBDIV 141.

        Both the U.S.S. BUSHNELL and SUBMARINE DIVISION 141 are
        to be extremely complimented on the fine quality and thorough-
        ness of the refit. It was with great pleasure and appreciation
        that we returned to a ship that was meticulously clean and
        materially perfect.

        We wish to further express our thanks not only to our
        refitting activities, but to the entire submarine organization
        at MIDWAY for their untiring efforts and their every
        consideration for making our stay one of the most pleasant
        we have ever experienced. The Submarine Force may look with
        pride on the spirit displayed by every activity in Task
        Group 17.5.

        Had five days of very beneficial training with COMMANDER
        W. T. LONG, USN, COMSUBDIV 141 as training officer.

        Departed MIDWAY 11 JULY 1945 for GUAM, arriving 20 JULY
        1945.

     While diving from 3 engine speed, our SD watch was
     "right on the ball" and left the SD mast up. Before
     it could be lowered, the force of the water bent
     the mast sufficiently to well jam it in the raised
     position. All subsequent efforts to force it down
     have failed and we will have to make the remainder
     of the patrol with the mast in the raised position.

Noon Position - LAT 7 - 49 N. LONG 106 - 58 E.

2 AUGUST 1945
1923(I) Sighted three two-masted cargo junks 210 T, 12 mi.
(Ship Contact #1). Closed for attack. All three
are not more than a mile off beach, just south of
HILTY CAPE, LOWER THAILAND.
2031 Passed inside of 10 fathom curve.
2037 We now have 3 fathoms of water under us. This is
poor employment for as valuable a fighting
unit as a U.S. Submarine, but this is the way we
must get our targets nowadays, so we rigged our
"keel wheels" and at
2039 Commenced firing 5" gun at near target (Gun Attack #1).
Range is 2,200 yds. but cannot close any more without
running high and dry. Crew has already abandoned
in boat.
2040 Ceased firing after three hits out of seven rounds
sank target. Other two junks practically beached
behind several large fishing weirs, so at
2042 Cleared to deeper water at 17 knots. Sun has just
set, but it is still quite light.

Noon Position - LAT 7 - 29 N. LONG 102 - 17 E.

sea trucks (Ship Contact #2). Commenced closing.
Again we must go into 5 fathoms and dodge several
reefs besides.

2006        Fired a few rounds of 40 MM at first junk to
            convince crew to abandon, which they did. (Gun
            Attack #2).
2008        Fired 1 round of 5" at 300 yards which hit at
            waterline and sank target.
2034        Fired 40 MM and 1 round of 5" at second junk - sunk.
2051        Fired 1 round of 5" at third junk - sunk.
            Sea trucks were anchored far behind reefs and
            well out of effective gun range, so at
2058        Cleared to deeper water.

            We have on each occasion and always will, given
            the crews chance to abandon, but none of them
            are worth one of my men, so will not take un-
            necessary chances by boarding to inspect cargo
            or to persuade the crew to abandon. A few well
            placed 40 MM shots convinces them much quicker.
            The value of these junks, although comparatively
            small, is very evident by just viewing their cargo
            capacity.

Noon Position - LAT 9 - 20 N. LONG 101 - 35 E.

4 AUGUST 1945
            Patrolling off LEM CHONG PRA.

0950        Sighted 3 two-masted cargo junks 260 T, 5 mi.
            and commenced closing. (Ship Contact #3).
1159        Battle surfaced.
1209        Commenced firing 40 MM at first target (Gun Attack
            #3).
1212        Crew abandoned in boat. Sank junk with 3 - 5" hits.
1217        Crew on target #2 abandoned. Sank with 1 - 5" hit
            and several 40 MM hits. Now closing target #3 which
            is ½ mile off beach.
1229        We have reached an all time low of 2 fathoms under
            keel, so commenced firing on target #3. Crew already
            ashore.
1234        Target #3 sank after 2 - 5" hits. Cleared to open
            water.
1331        Submerged.

297 T, 2 mi. (Ship Contact #4). Commenced
closing.
2243 Commenced firing with 40 MM. (Gun Attack #4).
Crew abandoned. Fired 5 rounds of 5" ammunition.
Not accurate shooting in dark. Got 4 - 5" hits
but did not hole below waterline. We therefore
went back to our system used last patrol. At
2303 Put bow up against target #1 and set her on fire.
We now had another junk 3 miles to northward so
commenced closing. At
2343 Commenced firing 40 MM. Crew abandoned in boat.
2359 Put bow up against target #2 and set her on fire.

5 AUGUST 1945
Attacking junks off LEM TONG LAN.
0005(I) With fire burning nicely to illuminate point of
aim, fired 1 round of 5" and several of 40 MM.
Target sank like a rock. Did not board, but part
of cargo seen to be either rice or sugar.
0008 Headed north to finish off target #1.
0029 Rekindled fire on target #1, then backed off and
sank with 1 round of 5". Continued patrol along

0037(I) Radar contact 310 T, 3,500 yards on what turned out
to be small coaster. (Ship Contact #6). For want
of something better to do, decided to go alongside
to inspect his cargo. Coaster became very elusive
and ignored our approaches so at
0140 Rammed him and put boarding party aboard. Had
no appreciable cargo of dried fish and cocoanuts.
That was food for someone, so took crew of 4 aboard
and set her afire. Fired several rounds of 40 MM

0740        to ventilate. (Gun Attack #6). Continued patrol.
0802        Off LEM CHONG PRA, closed beach to 500 yds, and
1831        put survivors ashore. Opened out from coast.
            Submerged.
            Sighted small coaster 292 T, 3 miles. (Ship Contact
            #7). We normally would not have paid much attention
            to this fellow but business was dull so decided to
1845        go after him.
            Surfaced. As we closed, target beached himself so
            close to less than 2,500 yds. He
            was too small for 5" and too far for effective 40 MM
            fire. However in chasing this fellow, we hit the
            jack-pot. At
1855        Sighted 7 two-masted cargo junks at anchor in hidden
            cove north of LEM CHONG PRA (Ship Contact #8) and at
1904        Sighted masts of 16 ships anchored in harbor off
            BANG SAPANNOI (Ship Contact #9). Had to round KOI
            TLU to get at them, so went to full on four engines.
1938        Rounded KOI TLU and headed west into harbor. Guns
            manned.
1950        With range 2,000 yds. and 1 fathom of water under
            keel, turned right to bring 5" gun to bear.
1953        Commenced firing 5" gun, mean range 1,800 yds. (Gun
            Attack #7). Targets are all moored and anchored.
            Practically every shot is a hit. 40 MM guns stand-
            ing by in case of aircraft.
2044        Ceased firing 5" gun. Expended 64 rounds of 5" ammo
            for 58 hits, sinking 16 vessels as follows: 6 - 250
            ton schooners, 1 - 180 ton schooner, 5 - 75 ton
            junks, 1 - 50 ton junk, 3 - 30 ton junks. Only one
            small 10 ton coaster remains afloat. (Diagram of
            attack is on next page). Sunset.
2045        Clearing harbor to eastward at 17 knots.
2107        Headed south. Plan to get 7 junks anchored north of
            LEM CHONG PRA by closing beach until we have 2 fathoms
            under keel, then sending boarding party over in two
            rubber boats.
2315        Boarding party left ship. It consisted of Lt(jg)
            HILL with 2 gunner's mates in one boat loaded with
            ammunition and small arms, and the EXECUTIVE OFFICER

(C) WEATHER:
The weather throughout the patrol was exceptionally
good. Less rain was encountered in the GULF of SIAM than
was expected.

(D) TIDAL INFORMATION:
None.

(E) NAVIGATIONAL AIDS:
No navigational lights were observed to be burning.

The soundings indicated on the charts for the west

However, in general the water depth of the east coast of
the GULF of SIAM was more shallow than indicated by the

DETAILS OF ACTION

Target group was sighted at anchor at 1904. Went ahead 17 knots
rounding KOH TLUI, then headed west to enter harbor.

At range 2,000 yards with 1 fathom of water under keel, turned
ship to right to bring 5" gun to bear, and stopped. What few
personnel there were aboard the targets, quickly abandoned as we
turned, so decided to use only 5" gun inasmuch as 40 MM would
not be too effective in holing targets at water line.

After turning with range 1,800 yards, commenced firing 5"
gun. Chose single targets starting with largest vessels first,
shifting targets as each was sunk.

(G) AIRCRAFT CONTACTS:

Only one enemy aircraft was encountered this patrol. On
6 August an EMILY was seen searching close to the MALAY COAST.

(H) MINES:

One floating mine was sighted and sunk on 1 August in the
following position: LAT 7 - 40 N. LONG 106 - 03 E.

(I) ANTI-SUBMARINE MEASURES AND EVASIVE TACTICS:

No anti-submarine measures other than the patrolling
mentioned in article (G) were encountered.

(J) MAJOR DEFECTS AND DAMAGE:

HULL AND MACHINERY
1. On 26 July, #4 main engine was flooded on surfacing as it was
turned over with the indicator cocks closed before engine
room personnel discovered the fact. Resulting damage
necessitated the replacement of liners for #1 and #9
units and complete piston and connecting rod assemblies for #9
unit.
2. A high commutator bar in the blower motor of the conning
tower air conditioning unit resulted in excessive brush
wear. Brushes had to be replaced twice during patrol.
The commutator was repaired during voyage repairs by
U.S.S. GILLMORE and the motor has been operating satisfac-
torily since then.
3. The Badger vapor compressor stills were out of commission
for a short period due to an apparent "locking" of the
feed regulator pump until the trouble was traced to a
broken spring in the brush rigging of the pump motor.
4. The auxiliary engine smoked persistently during the entire
patrol to the extent that it could not be used in the area.
It is believed that smoking results from a combination of
ring trouble and a dirty air box which could not be satis-
factorily cleaned at sea. It is recommended that this
engine be completely overhauled during the coming refit
with special attention paid to the air box.

(M) RADAR:

On diving for routine trim dive enroute to the area the
SD operator neglected to lower the mast on the sounding of the

jammed in the raised position. On arrival SUBIC BAY the top
steady bearing was removed and the mast lowered until the bend
was against the second bearing. Portable leads with a wooden
spacer were installed. Ranges out to 10 miles were obtained.

(N) SONAR GEAR AND SOUND CONDITIONS:

No casualties occured and no unusual sound conditions were
encountered.

(O) DENSITY LAYERS:

None were noted.

(P) HEALTH, FOOD, AND HABITABILITY:

The health of the crew was excellent. No man days were
lost throughout the patrol.

The food was very good.

It is suggested that separate small air conditioning units
be installed in individual compartments. The forward torpedo
room was especially hot during this patrol as it always has
been when patrolling in tropical waters.

          The 9250 kc frequency proved to be the best all-around
    circuit for reception of the NPG Fox schedules. Both 4370
    and 12,630 kcs were copied during the daylight hours, but
    faded out considerably at sundown. All the S.W.P. Fox schedules
    were characterized by heavy static and jamming of all kinds, but again
    with careful tuning we were able to keep a complete log. VIXØ's
    broadcasts during NVE rest periods were not received while in
    the GULF of SIAM.

          All transmissions were executed successfully with a minimum
    of trouble and interference except for one broadcast attempted
    to NPN while about 250 miles away from GULF. After trying to
    raise NPN or any shore station for over four hours finally trans-
    mitted the message blind three times. It was received for by
    NPG (Radio, San Francisco) who said that NPN had received two
    of our three transmissions, but apparently failed to "roger" for
    them. 12,705 kcs is by far the best ship-to-shore circuit. All
    the others, and particularly 4,235, were found to be far over-
    crowded, particularly from 1000 to 2100 GCT.

Subject: U.S.S. RAY (SS 271) - Report of War Patrol Number EIGHT.

1. The eighth War Patrol of the U.S.S. RAY, under the command of
Commander W. T. KINSELLA, U. S. Navy was conducted in the GULF OF SIAM during
the period 11 July 1945 to 22 August 1945. Twelve days were spent in the area.
The Patrol was terminated while at SUBIC BAY, P.I. replenishing ammunition due
to Japanese overtures for peace.

2. All contacts were with small coastal vessels carrying cargoes of
salt, fish, rice and sugar inside the 10 fathom curve along the east coast of
THAILAND. The results of this aggressive, smart "Short Range Battle Practice"
patrol in shallow water is an indication of the well trained gun teams in the
U.S.S. RAY.

3. Eight gun attacks were made resulting in the destruction of 35
vessels varying in size from 10 to 250 tons. Gun attack number seven was again
st 16 vessels sighted at anchor about sunset on 7 August. Shallow water pre-
vented closing the range below 1,800 yards. Deliberate 5 inch gun fire destroy-
ed all 16 vessels with 58 hits from 64 rounds fired. At 0105 on 8 August two
boarding parties in rubber boats boarded and fired seven junks anchored in
about four feet of water.

4. On her return from patrol the RAY was clean, shipshape and in
good material condition. Refit will be accomplished in 12 days by the crew of
the RAY assisted by U.S.S. ORION and Submarine Division 162 relief crews as
necessary.

5. The Division Commander congratulates the Commanding Officer,
officers and crew on the completion of this, their last patrol and regrets
that no torpedo targets were available. This dearth of torpedo targets is
due in no small measure, however, to the accomplishments of the U.S.S. RAY
on her seven previous patrols.

1. Forwarded, concurring in the remarks of the First Endorsement.

2. From its first patrol in the days of plentiful torpedo targets
to this final war patrol when only small coastal vessels could be found, the
RAY has displayed a continuous spirit of determination to inflict all possi-
ble damage on the enemy. The great increase in weight and efficiency of
submarine gun armament that has been evolved to cope with the changing situa-
tion of enemy shipping was exploited to the full by the RAY in this daring
and aggressive patrol. It is recommended that results be assessed as follows:

         (21 July to 22 August 1945).

1. The eighth war patrol of the RAY, under the command of Commander
W. T. Kinsella, U.S. Navy, was conducted in the Gulf of Siam.

2. This patrol was a normal offensive patrol. It is noteworthy for
the daring penetration into very shallow waters in order to seek out and destroy
the last remnants of the enemy's sea borne strength in this vicinity. In several
daring and very well conducted gun attacks, the RAY succeeded in sinking a con-
siderable number of small enemy sailing craft. On one occasion a boarding party
of two officers and four men from the RAY proceeded by rubber boat into waters too
shallow for the RAY to maneuver in and in a locality unsuitable for gun use in
order to destroy seven small craft. No contacts worthy of torpedo fire were
sighted.

3. Award of Submarine Combat Insignia for this patrol is authorized.

4. The Commander Submarine Force, Pacific Fleet, congratulates the
commanding officer, officers, and crew upon the completion of this very aggres-
sive patrol conducted in the courageous fighting manner characteristic of all of
the RAY's previous patrols. It is a pleasure to again welcome the RAY to the
Central Pacific. The RAY is credited with having inflicted the following damage
upon the enemy during this patrol:

(A) PROLOGUE

U.S.S. COD departed FREMANTLE, W. A. for
War Patrol No. Five on 18 September 1944, in accord-
ance with ComTask Group 71.1 Operation Order which
called for an independent patrol off the west coast
of southern LUZON. Subsequent to COD's departure,
it was decided to form a coordinated search and
attack group in the area previously assigned to COD
plus the area including PALAWAN PASSAGE. U.S.S. RAY
departed FREMANTLE on 22 September carrying general
wolf pack instructions and overlay grid chart of
area with copies to be delivered to COD at rendez-
vous in the area. Despatch orders were sent to COD
at DARWIN, N. T., forming the wolf pack. Voice calls
were assigned and Commanding Officer COD was ordered
to set rendezvous with RAY. It was expected that
RAY would arrive in the area 4 October.

(B) NARRATIVE:

Rendezvous was set for 0800 H, 5 October
in a spot 65 miles from nearest land off CAPE
CALAVITE, and COD departed DARWIN on 26 September,
returning that night due to a bow plane
casualty, and, after effecting repairs, again left
DARWIN the next morning. The time for the rendez-
vous was left unchanged, COD intending to make up
the difference by additional running on the surface.

On 3 October it became apparent that COD
would not be able to make the rendezvous but would
probably be able to reach a position in MINDORO
STRAIT by the morning of 5 October. I was very
anxious to have the coordinated search underway by
that time but was unwilling to issue despatch in-
structions while I was so far removed from the
scene. Accordingly, a despatch was drafted and
sent to RAY via VIGIL, instructing RAY to postpone
the rendezvous by 48 hours and telling him simply
to commence the search and that at daylight on
the fifth COD would be submerged north of APO REEF.

During the night of 4 October, RAY re-
ported negative results of search in the area (by
voice radio) and suggested patrol for himself off
CAPE CALAVITE, and for COD where originally intended.
This plan was adopted. On 5 October while submerged
north of APO REEF, COD contacted a southbound con-
voy of one large AK and 3 escort vessels.

- 1 -

— page 137 —
CONFIDENTIAL
In submerged attacks with ten (10) torpedoe s the AO
was sunk with six hits and there was evidence of dam-
age to the AK.
When both boats had surfaced, orders were
issued for the formation of a scouting line at 14
knots down PALAWAN PASSACE to search for the AK from
the COD's convoy. While proceeding to the initial
station for the scouting line, the RAY expressed the
belief that the convoy had anchored and would hug the
coast in the morning, and suggested a patrol south
of LUBANG ISLAND. In the heavy seas that were build-
ing up, I was unable to make more than ll knots and
I felt, too, that CCRON BAY was the most probable
destination of the convoy. Accordingly COD was
assigned a station five miles west of CAPE CALAVITE
and RAY 25 miles west for the following day. It was
my intention that both of these patrols be submerged
patrols and it was my belief that the stations covered
as effectively as possible any route that would be
taken by a convoy between ANILA and CORON BAY or
PALAWAN PASSAGE, passing either east or west of the
LUBANG ISLANDS. The rendezvous was still set for the
morning of the seventh.
Apparently after surfacing on 6 October,
RAY made a sweep around to the north of CABRA ISLAND
and picked up a convoy consisting of one very large
AQ with one DD type escort and one small engi m s-aft
escort.
RAY got off a contact report, fired a six
torpedo salvo at the tanker, obtained one hit, and
was forced deep by an escort. His radio transmitter
and SD mast were flooded at this time. (All state-
ments of fact relative to the RAY are the facts as I
believe them to be, but are subject to checking with
the RAY's patrol report). COD, 45 miles away when
the contact report was received at 2203 H, ma de SJ
contact at 2342 H and commenced tracking. I was wait-
ing for an indication that the RAY's initial attack
was completed. I did not know that it was already
finished. I knew that the RAY would be closing until
his attack was completed and yet I had received no
message from the RAY since the initial contact report.
SJ interference was present on the screen. COD sent
composition course and speed of convoy to RAY in voice
code and by 0100 H had almost decided to make an attack
without regard to possible interference from RAY. At
0104 Hon the seventh, RAY challenged by SJ radar and
sent word by this means that his transmitter was out
and that hewas working up ahead for an attack. At
0145 H COD sent a message blind by voice frequency

- 2 -

— page 138 —
CONFIDENTIAL

that he was diving to attack, submerged ahead of
convoy, and fired four torpedoes at 0232 H, two
hits being heard and seen by RAY. COD was driven
deep and surfaced at 0449 H. RAY made the third
attack on this tanker at about 0514 H with six
torpedoes, four torpedo duds and hearing four ex-
plosions which were also heard through the hull by
COD. COD took up the chase and tracked the tanker
to the shoals north of BUSUANGA but was unable to
get position for another attack. The target was
observed to be a very large tanker of about 15,000
tons with three masts. One mast was broken, it
was listing heavily, and had visibly settled in the
water when last seen, but was still making 10 knots.
It may very possibly have sunk before reaching
haven but was not observed to do so.

On the evening of 7 October rendezvous
was set for dawn of the eighth. At the rendezvous
information was exchanged on the attack and it was
learned that RAY's transmitter was working, that
the SD radar was out, and that he had lost three
Mark 18 torpedoes by explosions, leaving him four
torpedoes forward and five aft. COD at this
time had six torpedoes forward and four aft.

At the rendezvous RAY suggested a sub-
merged patrol of one or two days in VERDE ISLAND
PASSAGE. It was his desire that both boats be
placed on the line between CAPE SANTIAGO and GOLO
ISLAND lights. On the way to the area I had given
considerable thought to the matter of stationing the
boats for the most effective coverage. I had four
patrol stations laid out in VERDE ISLAND PASSAGE
and CALAVITE PASS, as well as stations at various
intervals west from CAPE CALAVITE, southwest
north, northwest, and west of
CABRA ISLAND, west from CAPE CALAVITE, southwest
from PALUAN BAY and north of APO REEF. In addition
I had been considering stations at the northern en-
trance to the DANGEROUS GROUND and sweeps up and
down PALAWAN PASSAGE. It appeared to me that the
most productive mode of patrol for the time being
would be by on and off stations during the day
between CAPE CALAVITE and CABRA ISLAND, with
more extended searching at night. It was my in-
tention to exploit the DANGEROUS GROUND and PALAWAN
PASSAGE in case anti-submarine measures should
become too active at the inshore focal points. It

- 3 -

— page 139 —
CONFIDENTIAL

was my intention to save the submerged patrol in VERDE
ISLAND PASSAGE for exploitation in case the other
points should prove non-productive. Recent observed
movements through the passage had been chiefly by small
inter-island ships, whereas oil-carrying bottoms must
of necessity run continually from MANILA to the south-
west. In other words, the additional navigational
risks of patrolling in the passage were not justified
at the time.

Assigned patrol stations northwest from
CABRA ISLAND, COD close in, RAY about 25 miles off.

While en route to station on 8 October, COD
contacted an unidentified CM of 1500 tons, and fired
bow torpedoes which the target avoided by maneuvering
and combing the wakes. At dark on 8 October I sent
orders establishing a north-south patrol line 70 miles
west of CABRA ISLAND light. This was designed to
intercept any traffic heading between MANILA and MALAY
points by routes north of DANGEROUS GROUND, and was
to let the enemy complete any hunter-killer search
that they might be conducting in the CABRA-CALAVITE
area. A ten-ship southbound convoy passed 25 miles
west of our line the next day, and was apparently
attacked by CAVALLA and BECUNA, but word did not reach
us of this until they were 90 miles away.

RAY asked for how long a time the patrol
line was to be run, and if he was to submerge. It was
my intention that the line be run on the surface, but
not knowing the condition of the RAY's SD radar I
left this to his discretion, assigning him a line of
the length in case he wished to run it submerged.

At dark on 9 October RAY reported no con-
tacts and suggested patrol in VERDE ISLAND PASSAGE for
the following day. I assigned the RAY a daylight
patrol five miles northwest of CABRA with the COD 25
miles off, and a patrol at night south of LUBANG, with
the COD north of LUBANG. I determined that RAY's SD
radar was now in operation.

At 2200 H on 9 October decoded report from
the BECUNA of attack on convoy at 1700 H in latitude
12° 45'N longitude 118°E. I could not make out from
the report whether BECUNA had lost contact, nor whether
the convoy was headed into the DANGEROUS GROUND or
PALAWAN PASSAGE. The convoy would be at least 90
miles from COD at this time and farther from RAY.

At 2305 H 9 October decoded report that
CAVALLA had sighted a convoy at 1200 H 9 October in

- 4 -

CONFIDENTIAL

latitude 13° 13'N longitude 118° 22'E. The two posi-
tions showed the convoy headed for DANGEROUS GROUND.

At 0125 H on 10 October decoded report
that HAWKBILL had sighted convoy going into north
end of PALAWAN PASSAGE at 2300 H. At this time
COD went to four engines and headed south for PALAWAN
PASSAGE. Estimated situation. Convoy had a lead
of 150 miles from COD and 20 miles more from RAY.
We had a nine-knot speed advantage; fuel was a
factor; we had no report of any boat trailing this
convoy after reporting it. If, after experiencing
a successful attack, the convoy did not hole up in
the nearest shoal water, it would be the first low
speed convoy in this area not to do so to my know-
ledge. I decided not to form scouting line re-
versed course, and headed for previously assigned
station north east of CABRA.

At 0333 H, 11 October, RAY, south of LUBANG,
reported a destroyer northbound through CALAVITE
PASS at 15 knots. COD could not intercept. On 11
October received orders that all boats would stay in
assigned areas and that readjustments and extensions
of patrols would probably be forthcoming. RAY re-
ceived orders to proceed to an area to the north-
ward at dark 14 October. COD received orders to
commence surfacing 16 October. At 0417 H 11
October, RAY reported he could not make his station
off CABRA by daylight without excessive fuel con-
sumption and requested permission to patrol off
CALAVITE, which was granted. COD remained northwest
of CABRA, closing the light during the day.

For 12 October, RAY was assigned daylight
patrol close to CALAVITE with COD 20 miles west. At
1331 H RAY sank a large ammunition ship five miles
north of CALAVITE light on course 235°T with an es-
cort of two CHIDORIS. COD heard and saw the tremen-
dous explosion, surfaced, and closed the CAPE to
look for possible remnants. COD was forced down by
plane at 1500 H. After dark RAY and COD tracked the
CHIDORIS, each thinking at the time of first contact
that he had made contact on a convoy.

During the tracking both submarines were
thrown on the port flank, due to the course changes
of the CHIDORIS, who were making a sweep off CALAVITE
looking for RAY. COD felt at this time that more
information from the RAY would help, but the RAY
was apparently occupied at the time in closing the

- 5 -

— page 141 —
CONFIDENTIAL
contact for visual identification.

RAY requested a patrol in VERDE ISLAND
PASSAGE and was assigned a patrol north of CABRA and
LUBANG ISLANDS for 13 and 14 October, with COD south-
west of CAPE CALAVITE.

13 October was uneventful. During darkness
in the early morning of 14 October, RAY flooded his
conning tower while diving for a night plane. No
personnel casualties were suffered but damage was sus-
tained to the SJ radar, sound units, periscopes and
hoist motors. RAY departed area for advanced base in
accordance with despatch orders from ComSubFor 71,
thus terminating the coordinated search and attack.

(C) SHIP CONTACTS:

Ship contacts were numerous, as is generally
the case when operating with an officer of the caliber
of KINSELLA, who aggressively and doggedly goes out to
look for them.

It is my belief that the proper number of
boats to exploit the southwestern approaches to MANILA
is three (3), their basic stations being one (1) in
CALAVITE PASS and two (2) northwest of CABRA ISLAND.
I believe VERDE ISLAND PASSAGE can be more effectively
covered by a boat stationed at the eastern entrance.

It was my intention, and I am sure it was
KINSELLA's also, to fire all torpedoes and then request
a reload at the advanced base. The developments of
the strategic situation made it appear as the patrol
progressed that we would be required in the area if
only for reconnaissance.

(D) AIRCRAFT CONTACTS:

Aircraft contacts were numerous both by day
and by night, and led to the withdrawal of RAY from
station. I was unable to determine that any planes or
group of planes encountered had a definite anti-sub-
marine mission, other than those planes actually es-
corting ships. The next boat in this area reported an
air field on LUBANG ISLAND.

(E) ANTI-SUBMARINE MEASURES:

Patrol craft were encountered in the area as
noted in individual war patrol reports.

- 6 -

— page 142 —
CONFIDENTIAL
(F) COMMUNICATIONS:
Communications were by voice modulation
on 2880 kcs. Aircraft contact code or plain language
was used and no difficulty was encountered.

It is believed that the FAY's action was
worthy of note, in that when his radio transmitter
was out of commission, he sent vital information by
means of keying the SJ radar. It is my wish to em-
phasize, however, that while the SJ radar is being
used for communication purposes it can not be used
for tracking. The FAY's use of the SJ for communi-
cation purposes on this occasion enabled the two
submarines to make three attacks on a tanker without
interference between boats. The use of the SJ on this
occasion is considered highly commendable and worthy
of comment. But I look upon the use of the SJ for
communication purposes, as a stop-gap, indicating
that we lack the proper tool for the job. I would
rather see the TBS reinstalled, than sacrifice even
a few seconds of valuable search by the SJ radar.
The VHF may be the answer to this problem, but I
have had no experience with this equipment in sub-
marines.

(G) REMARKS:

The number of torpedo hits required to
sink a Japanese tanker would appear to be increasing.

Rapid exchange of sufficient information
remains the time-worn problem of forces in battle.

When operating with Commander W. T. KINSELLA,
this problem is simplified, even with no means of
communication at hand. One has only to listen for
the explosions to form a reasonably accurate idea of
what he is doing.

CONFIDENTIAL U.S.S. RAY (SS271)

2000 14 November 1944 (Cont'd).
     RAY makes radar contact on two ships on starboard and port flanks re-
     spectively. RAY commenced tracking on port flank 5000
     yards on port quarter of BATFISH.
     Convoy consisted of 3 or 4 large AK's or AP's and 4 or
     more escorts, base course 000 T, speed 8 knots.
2033 A large zig to left (320 T) placed both RATON and BATFISH
     on starboard flank. RATON was closing for attack. RAY
     was closing for attack on port flank.
2114 RAY attacks with six torpedoes, sinking large gasoline
     loaded AK with four hits and damaging or possibly sinking
     an escort with one hit (Lat. 17-46 N., Long. 117-57 E).
     Following attack RAY was forced to dive to escape detection
     and gun fire from escort, therefore the exact times and
     details of the attacks of RATON and BATFISH are not known
     at time of writing this report.
     It is known however that RATON made two attacks following
     RAY attack and before midnight.

0005 15 November 1944
     RATON reported sinking 3 AK's. BATFISH reports he is going
     in for attack on remnant of convoy.
0105 BATFISH reports sinking 2 unidentified ships with 3 hits
     out of 4 torpedoes fired.
     At this point, the only ships left in convoy were two escorts
     which had remained behind to depth charge RAY when she sub-
     merged. Inasmuch as their movements were very erratic and
     there was great possibility of torpedoes running
     under, ordered group to retire eastward.
1735 Reported pack results to CTF 71, who ordered RATON and
     BATFISH to pass to control CTF 17 and proceed to PEARL.

COMMUNICATIONS
     Communications were by voice radio on 2880 kcs. and by SJ
     radar keying when in close enough contact to use this
     method.
     No difficulty was experienced in establishing com-
     munication on 2880 kcs. but the frequent appearance of night
     flying planes indicated interception and DF of our trans-
     missions. The plan of shifting frequency every six hours
     as used by Task Force 17 boats is believed to be very wise
     and should be used by all submarines.
     A VHF channel for exclusive use by submarines when in
     contact with and attacking enemy convoys is recommended.
     This would enable rapid communication in plain language,
     eliminating the delay caused by encoding and decoding.

U.S.S. RAY (SS271)
COMMUNICATIONS (Cont'd)
The aircraft code (CSP 1270 series) is entirely too
cumbersome for use between submarines under conditions
where rapid communication is essential. It is recommend ed
that a code be made up for submarines employing well known
submarine terms and phraseology.
DAMAGE
On the basis of information available at this time, the
following damage was inflicted upon the enemy by this group.

|         | SUNK    | DAMAGED        |
