HISTORY OF USS BAYA (AGSS 318)

The first quarter of 1943 reflected the accelerated submarine
production in the U.S. Peacetime building had averaged about six new sub-
marines a year. Now a new boat arrived at Pearl Harbor almost every other week,
where the crew ran through final training exercises with precision, and sallied
forth to win combat insignia in the contest for control of the seas. It was
during this mass production period that the keel for the SS 318 was laid on 8
April 1943 in the yards of the Electric Boat Company, Groton, Connecticut.
Just nine months later, on 2 January 1944, she said laid down the ways as the USS
BAYA, christened by Mrs. C.C. Kirkpatrick, wife of Lieutenant Commander C.C.
Kirkpatrick, USN. The BAYA was named for a brown fish of the grouper family
which is found around the rocky shores of the Pacific Coast of Mexico. They
are very voracious and have extremely large mouths, being able to swallow
prey about half their own size.

At the commissioning exercises on 20 May 1944 Commander Arnold H.
Holtz, USN, came aboard as commanding officer, and training and sea trials
began in the New London area. On 25 June the new sub sailed for Pearl Harbor
via the Panama Canal. At Pearl Harbor a final training period put the finish-
ing touch on the operating and battle efficiency of the crew. On 23 August
1944 the BAYA sailed from Pearl Harbor headed toward the Japanese Empire in
company with the BECUNA and the HAWKBILL. After topping off at Saipan, the pack
proceeded to Palau where they joined a reconnaissance line formed in connection
with the invasion of the island. This line, known as the "Zoo", was composed
of three such wolf-packs. While the amphibious landings of Peleliu and Anguar
were in full swing a fast carrier force moved north and west to strike at
Manila. The "Zoo" line moved to the northward to clear the submarines off the
THIRD Fleet's track. The line was again shifted in the third week of September
as Halsey's forces raced on north to attack the northern Philippines, Formosa,
and the Nansei Shoto. For the submarines it was a month of heavy seas, plane
contacts, and no shipping. On the night of the 25th, while on patrol in Luzon
Strait, she was driven down by a plane. About 30 minutes later she surfaced
with all hands at battle stations, and the executive officer, engineering
officer, and quartermaster went up to the bridge. The sea was rough, but no
more so than earlier in the evening. With the boat "well blown up" and the
bridge personnel topside, the main induction was opened, preparatory to start-
ing the engines. The next moment a hill of ocean hovered over the BAYA's stern.
Then it rushed forward with a roar and whirled the three submarines off the
bridge. The BAYA shuddered, staggered, and started to settle. Before the main
induction and the conning tower hatch could be closed she dived to 45 feet.
The well-trained crew responded to the emergency with quick action; drained the
conning tower, blew the ballast tanks, and surfaced the partially flooded ship.

Twenty minutes later the men washed overboard had been recovered and the damage
was speedily repaired. The ship's life preserver was lost during the incident,
and several months later a Japanese radio broadcast announced the confirmed
sinking of the BAYA.

On the night of 7 October, while patrolling independently in the middle
of the South China Sea, the BAYA was given her first opportunity to fire
torpedoes in action. Radar contact was made on an 8,407 ton passenger cargoman

with two escorts, and the approach was begun. Meanwhile the HAWKBILL had also
made contact and was giving chase. After tracking for an hour the two sub-
marines converged upon the convoy. The HAWKBILL's first attack was unsuccessful
The BAYA submerged to radar depth, closed range, and fired a full salvo from
the bow tubes for two more hits. The HAWKBILL then fired three torpedoes at close
range for two more hits. Bursting pyrotechnics floated into the black sky.
Within seconds the doomed KINUGASA MARU exploded with a roar, spewing fire and
debris.

Two days later the BAYA was ordered to Fremantle, West Australia. She
left the area proceeding via Karimata Strait, Java Sea, and Lombok Strait,
arriving 22 October. In company with the CAVALLE she departed Fremantle on
her second war patrol after a normal refit and training, but a shaft squeal
necessitated return to port. Underway again five days later the BAYA returned
to the South China Sea to form a pack with the CAVALLE and HOE. On 8 December
contact was made on a single destroyer. She began a submerged approach in
heavy seas with low visibility. Despite difficulty in maintaining depth control
the range was closed. Then right at the firing position, the target changed
course forcing the BAYA deep to avoid being rammed and thwarting the attack.
Two destroyers were sighted the following day headed north at high speed, but
they could not be closed for attack. On the 10th a properly marked hospital
ship was allowed to proceed peacefully on its way.

After this series of contacts the BAYA shifted stations and joined the
submarine scouting line deployed off Mindoro Island during its occupation 14
through 25 December. While changing areas to the westward, a major enemy task
force of two heavy cruisers escorted by four destroyers was contacted on the
night of 27 December 1944. These ships were evidently attempting to flee the
Philippine area, and a contact report was transmitted and the range closed for
attack. Reaching the attack position she submerged to radar depth ahead of
the enemy, but difficulties in depth control necessitated carrying out the
attack by sound. At medium range, a full bow salvo was fired at the leading
cruiser, but no damage was inflicted. The patrol was terminated by orders to
proceed to Fremantle, West Australia via Karimata and Lombok Straits, where
she arrived 12 January 1945.

At Fremantle the routine refit was accomplished alongside the ANTHEDON,
during which time Commander Holtz was relieved by Lieutenant Commander Ben C.
Jarvis. On 19 February 1945 the BAYA sailed on her third patrol in company with
the HAMMERHEAD, and proceeded to her area off Cape Varella, French Indo-China.
The first contact on 26 February consisted of four small ships headed northward
along the coast. At dawn the targets were identified as patrol craft, and
unworthy of torpedo fire. Shore-based enemy radar, night flying radar planes,
and numerous sailboats were constantly in evidence in this sector, and on the
27th a hospital ship was sighted headed in a southerly direction.

A five-ship convoy consisting of one tanker, one large freighter, and
three escorts was detected by radar during the night of 4 March. A calm sea
and bright moonlight with a slight inshore haze favored the enemy's position.
The BAYA's approach was additionally hampered by numerous sailboats in the area.
From radar depth she fired six torpedoes. Two hits were scored on the 5,236
ton tanker, PALEMBANG MARU, which promptly exploded in a tremendous blaze. Two

more hits damaged the freighter but the extent of the damage was obscured by the
fires from the sinking tanker. The BAYA went deep and sat out the forty-two
depth charges delivered by their escorts. No damage was sustained, and she
rejoined her wolf pack in the Camranh Bay area.

At 2200 on 20 March she contacted a single ship leaving Phang Rang Bay.
A stern tube salvo of three torpedoes were fired for one hit to sink the 524
ton submarine chaser, KAINAN MARU, about 1600 yards off shore. Planes and
coastal radar were particularly active following the attack, but at 0400 the
following morning a convoy of two destroyer escorts and another sub chaser
emerged from the bay with an airplane escort. Conducting a periscope attack,
a spread of three torpedoes was fired from the stern tubes. Sound reported two
erratic runs, and no hits were obtained. The sub chaser had now detected the
BAYA, passed directly overhead, dropping six close depth charges. The patrol
ended upon her arrival at Subic Bay on 27 March.

The BAYA and CAVALLA departed Subic Bay April 20th to return to the
Camranh Bay area. Submerged patrolling was combined with lifeguard duty for
air strikes over Saigon. On 2 May she joined the LAGARTO on station in the
Gulf of Siam just north of Singapore. The next night the BAYA contacted a
four-ship convoy comprised of two gasoline-loaded tankers and two radar-equipped
escorts. She maneuvered into attack position for a night surface engagement
and began firing bow tubes at extreme range. After the first two torpedoes
passed the leading escort, a minelayer, swung toward the BAYA at high speed
and the other three ships turned away. The BAYA changed course at flank speed
to prevent being rammed, and was passed at 900 yards in a hail of gunfire.
Unable to dive in seven fathoms of water, the BAYA began firing first of four
down-the-throat shots to drive away the pursuer, who gave up the chase after a
half-hour display of fortunately erratic shooting.

The BAYA sent a report to the LAGARTO requesting a rendezvous, and the
two submarines met early the following morning to discuss attack plans. It
was agreed that the LAGARTO would dive on the convoy's track when a certain
point was reached, and the BAYA would strike from a point some 12 miles ahead
of the LAGARTO. The submarines parted company, and the convoy chase was on.
The subs exchanged contact reports during the day, and the LAGARTO attacked with
no success. At midnight the BAYA attempted another surface attack before
moonrise, but was again driven off by the unusually alert escorts. No further
attempt was made. Early the next morning the BAYA tried to contact her team-
mate. The LAGARTO made no reply. The silence is still unbroken. Post-war
Japanese records reported an attack on a submarine by the minelayer at that
time in 30 fathoms of water - a depth which gave the submarine little chance
for evasion.

Shifting now to the Java Sea, a three-ship convoy was attacked just off
Rembang Roads on the morning of 13 May 1945. A tanker, a medium freighter, and
a minelayer escort were detected leaving the Roads, and a radar surface approach
was begun on the tanker which was hugging the coast inside the ten-fathom curve.
Racing in at high speed, the BAYA fired six torpedoes for three hits. Reversing
course, she shifted to the escort and scored two hits with the two remaining
stern tube torpedoes. Two torpedoes were left forward, and these were fired
into the freighter. The BAYA retired leaving the 2500 ton tanker, YOSEI MARU,
sinking, and the other two ships severely damaged. Five days later a refit was
underway in Fremantle alongside the CLYTIE.

A fire in the maneuvering room delayed her departure for the fifth
patrol, and it was not until 20 June that she got underway. The first part of
this run was devoted to support of the landings at Balikpapan, Borneo. While
south of Cape Selatan, a single target was intercepted on the morning of 27
June. Six torpedoes were fired at the minelayer from periscope depth. Three
passed under the speeding ship, and no hits were scored. Smoke sighted by the
periscope watch on 29 June led to an approach on three sea trucks, one patrol
craft and a sub chaser. As a torpedo attack was about to be launched, the
targets became alerted, so a coordinated gun attack with the USS CAPITAINE was
made resulting in sinking the sub chaser and damaging the two sea trucks. Heavy
return fire prevented further attack.

During the following two weeks, lifeguard duties were performed for
raids on Kota Warigen. On the morning of 16 July a 595 ton torpedo boat was
attacked from a range of 1100 yards. One hit in the stern set the ship ablaze
and stopped it dead in the water. An hour later another hit demolished the
KARI. On the 20th a PC-4 patrol craft was encountered off Surabaya. It was
too small for torpedo fire, and at dawn the BAYA merged her efforts with the
BLENNY in a gun attack. The enemy was chased back to port, but no damage was
inflicted. Five days later the BAYA was ordered to Subic Bay, thus ending
her last patrol.

Two weeks after V-J day the BAYA departed for San Francisco, and on 24
September steamed under the Golden Gate Bridge as part of Admiral Halsey's
symbolic parade. During 235 days at sea she had cruised 50,722 miles -- she
was due for a rest.

The USS BAYA earned four Battle Stars on the Asiatic-Pacific Area
Service Medal for participation in the following operations:

1 Star/First Submarine War Patrol -- 23 August - 22 October 1944
Western Caroline Islands operation -- 31 August - 14 October 1944

1 Star/Third Submarine War Patrol -- 10 February - 27 March 1945

1 Star/Fourth Submarine War Patrol -- 20 April - 18 May 1945

1 Star/Fifth Submarine War Patrol -- 14 June - 31 July 1945

On 14 May 1946 the ship was decommissioned and placed in reserve at
Mare Island Naval Shipyard. After lying in mothballs for less than two years,
the BAYA was recommissioned on 10 February 1948, and converted to an Electronics
Experimental Submarine. All torpedo loading and stowage equipment was removed
at the Mare Island Navy Yard to make room for Navy Electronics Lab
personnel and equipment; except the torpedo tubes were left intact. Commander
John D. Mason, USN, was the first commanding officer upon re-commissioning.

Since that time the BAYA has acted as an undersea "guinea pig" in close
liaison with the Navy Electronics Laboratory, San Diego, California. Besides
participating in local operations within 600 miles of San Diego, the BAYA was
a member of a joint American-Canadian Task Force gathering scientific data off
Western Canada in November and December 1948. During the period July-September

— page 5 —
-5- USS BAYA (AGSS) 318

1949, she made a cruise to the Arctic to gather scientific data in the Bering
and Chukchi Sea. Lieutenant Commander Jack S. Ross, USN, relieved Commander
Mason in September 1950.

Although concerned primarily with Electronics Laboratory tasks, the
BAYA is still a submarine. Originally assigned to Submarine Division 72 in
1948, she was shifted to Submarine Division 31 in January 1950, and to Sub-
marine Division 33 in January 1952. Lieutenant Commander Philip B. Taliaferro,
USN, relieved as commanding officer in May 1953. In April 1953, the BAYA began
a shipyard overhaul at Pearl Harbor Naval Shipyard; the first West Coast
based submarine to be overhauled at the shipyard since World War II. In August
1953 Lieutenant Commander Charles B. Bishop, USN, came aboard as skipper. Thus
the USS BAYA continues to serve her country in peace as well as war.

2030 Surfaced - Executive Officer, Engineering Officer,
and quartermaster went to bridge. Boat was well
blown up. Main induction opened. Boat start-
ed to settle. Blew all ballast tanks. Started to
take water in the Conning Tower. Main induction
was closed, both conning tower hatches were closed,
all bulkhead flappers were closed. Surfacing in
the area with all hands at battle stations paid
dividends this time. Main induction was partially
flooded and about 12 inches of water was taken in
the Conning Tower. Boat settled to 45 ft. Drain-
ed Conning Tower, blew up, and surfaced. Man-
euvered for about twenty minutes to pick up two
officers and one quartermaster, all hands, in-
cluding the C.O., grateful that our plane friend
did not bother us during this period. There was
no damage that a few hours of hard work could not
remedy.

            Sighted 3 sailboats during day. Observed either
            an observation tower or radar installation on
            top of Surung Gading Island.

1922        Surfaced in very poor visibility forty six min-
            utes after sunset, 5 miles off Serutu Island.

1939        Serutu Island light came on with very greatly
            reduced brilliancy. Shortly thereafter a second
            light - definitely a signal lamp of some kind -
            flashed a series of characters - this was re-
            peated three times.
            Probably these lights were mere coincidence, but
            the Commanding Officer feels strongly that we
            were detected, not visually, passing Serutu Is.

       tact No. 2). Tracked for one hour on course
       175°, speed 7. Contact was headed for entrance
       to safety lane. Because of the very weak SJ
       course, speed, the unlikelihood of enemy ship-
       ping in this position, and the eight boats head-
       ed south, the Commanding Officer believed this
       to be either a submarine or a patrol and did not
       close to investigate.

(C) WEATHER.

     No unusual weather - on the whole the weather was
much better than the Sailing Directions predicted
for this time of the year in our areas.

(D) TIDAL DATA.

     Currents observed were irregular and unpredictable
as noted in Sailing Directions.

(E) NAVIGATIONAL AIDS.

     One navigational aid was sighted: Serutu Island light,
Lat. 1-43, Long 108-42. This light was lighted with
reduced visibility. In passing between Amatahan and
Sarigan Islands enroute Pearl to Saipan, excellent
radar fixes could be obtained with these islands at
ranges up to 40 miles.

     The islands of the Batan group were excellent land-
marks for radar fixes in a night passage of the
Bashi Channel.

NIGHT CONTACT AND TORPEDO DATA
TYPE ATTACK

Night radar attack. 2134 radar contact
180° T, range 27,000 yards - closed for
attack. 2157 - 2208 heard a series of
explosions (sounded like depth charges)
from direction of target, and immediately
noticed a course change to 290° T. This
course change was 90° away from the orig-
inal course. 2214 picked up escort at 15,
000 yards on port quarter of target moving
fast toward the bow. 2218, at range
10,000 yards, dived for radar approach.
Target was sighted from bridge at 12,000
yards. After diving could not pick up
escort with radar. Escort pinging, and
after pinging steadied on us, and had
a constant bearing on the bow. Decided
to accept long range (3800 yd run) and
fired the bow nest at 2230 - track 67 port

CONFIDENTIAL
FIRST ENDORSEMENT to
U.S.S. BAYA - Report
of First War Patrol.

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

Subject: U.S.S. BAYA (SS318) - Report of First War Patrol.

1. The first patrol of U.S.S. BAYA covered a period of 60 days,
30 of which were spent in the Philippines - South China Sea area, as one
of a coordinated patrol group consisting of BAYA, BECUNA, HAWKBILL, with
the Commanding Officer, BAYA, as officer tactical command.

2. Area coverage was good, 12 days of the 60 being spent sub-
merged. Ship contacts were very scarce. Only one contact worthy of tor-
pedo fire was made, and this was developed into a successful attack.

3. Six torpedoes were fired on one night submerged attack,
and two hits obtained:

Torpedo Attack No. 1: On the night of 7 October, acting on
information transmitted by HAWKBILL, BAYA contacted and closed
a large escorted AK. Later events proved this to be, not the
ship reported by and eventually destroyed by HAWKBILL, but an-
other similar ship in the near vicinity. Six Mark 23 torpedoes
were fired at a range of 4400 yards, and two timed hits resulted.
BAYA was forced deep by escort, and one-half hour later unmistakable
explosion and breaking-up noises indicated the sinking of this ship.

4. BAYA is in good material condition. The cause of the re-
ported casualty to the auxiliary engine will be found and necessary repairs
will be made. All four main engines were used equally while on patrol,
necessitating a 4-engine overhaul, which places undue load on the relief
crew. However, with the exception of 59 out of 64 connecting-rod bearings
needing renewal, the engines were in excellent condition. Relief will be
accomplished by Submarine Repair Unit, Navy 137, and Relief Crew 6-2.

5. The Commander Submarine Squadron TWELVE congratulates the
Commanding Officer, Officers, and Crew for the damage inflicted on the
enemy and welcomes BAYA to this area.

Report of First War Patrol.

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

Subject: U.S.S. BAYA (SS318) - Report of First War Patrol -
Comment on.

1. BAYA's First War Patrol was conducted with BECUNA
and HAWKBILL in a coordinated Search and Attack group commanded
by BAYA's Commanding Officer, Commander A. H. HOLTZ, U.S.N.

2. Offensive reconnaissance east of the PHILIPPINES was
performed for two weeks with no contacts. After transferring to
operational control the Group patrolled in the SOUTH CHINA SEA
North of DANGEROUS GROUND. BAYA's only contact was on a large AK
with one escort. The AK was sunk in a submerged night radar attack.

3. The flooding of the conning tower during surfacing
operations in the patrol area is noted with concern. This is the
second incident of this nature in this Force during the last two
months. All Commanding Officers are directed to review their diving
and surfacing procedure to ensure that all unsafe practices are
eliminated. BAYA's sound practice of having all hands at Battle
Stations when surfacing in the Area undoubtedly prevented more
serious results.

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

5. The Force Commander welcomes BAYA's Commanding
Officer, Officers, and Crew to this Force, and congratulates them
on inflicting the following damage to the enemy:

FIRST ENDORSEMENT TO
USS BAYA (SS318)
Report of Second
War Patrol.

SUBMARINE SQUADRON TWENTY SIX
Rr
Care of Fleet Post Office,
San Francisco, California,
18 January 1945

From: Commander Submarine Squadron TWENTY SIX.
To : Commander-in-Chief, UNITED STATES FLEET.
Via : (1) Commander Submarines, SEVENTH FLEET.
 (2) Commander SEVENTH FLEET.
Subject: USS BAYA (SS318) - Report of Second War Patrol.

 1. BAYA's second war patrol covered a period of 53 days, 43 of which
were spent in areas north of the Malay Barrier. BAYA was one of a coordinated
attack group composed of BAYA, CAVALLA, and HOE, with Commander Holtz, Commanding
Officer BAYA, as Group Commander. This group formed on 3 December in the South
China Sea and functioned as such until 9 December when all were directed by
Commander Task Force 71 to take assigned positions on an assigned scouting line
in the eastern South China Sea.

 2. Area coverage was somewhat hampered by bad weather and poor visibility.
Only four worthwhile contacts were made, two of which were destroyers, one a
hospital ship properly marked, and the fourth a formation of 5 or 6 ships, which
were attacked, but which were never identified as to type.

 3. On 8 December at 0700, a Matsu type DD was sighted at a range of
16,000 yards. A submerged attack on this ship, in an extremely rough sea,
failed of consummation because of a range of 1,700 yards, with a zero angle on the
bow. BAYA went deep. There was no later indication that the submarine was
detected. The following day two destroyers were sighted, heading away at high
speed, and no attack was possible.

Torpedo Attack No. 1.
 On 27 December after dark, radar contact was made at 18,000 yards on a
formation which developed into 5 or 6 ships. After tracking for one and one
half hours, BAYA submerged to radar depth, but found it impossible to maintain
this depth, due to rough seas. The approach was completed by sound and periscope,
and six torpedoes fired at what appeared to be the largest target. BAYA went
deep after firing and several explosions, not identified as to type, were heard.
It is possible that one or two torpedoes hit, but analysis and evidence indicates
that this is improbable. It is likely that the explosions were haphazard depth
charges dropped by the escorts.

 4. BAYA reached Fremantle in good material condition, except for the main
storage battery, which has some evidence of superficial sulfation. Refit will be
accomplished in the regular time, and it is expected that two successive equalizing
charges of the storage battery will restore it to its former satisfactory state.

 5. The Squadron Commander notes with satisfaction the completion of this
arduous and tiring patrol and hopes that the next patrol will present more opport-
unities to inflict damage on the enemy.

Comment on.

1. The Second War Patrol of the BAYA was conducted in
the areas of the SOUTH CHINA SEA as a member of a Coordinated Search
and Attack Group which was composed of BAYA (OTC), HOE and CAVALLA.

2. The first attack took place on 27 December when a
night submerged attack was made on a convoy. Heavy sea made depth
control difficult, and the attack was completed by sound bearings.
Six torpedoes were fired from a range of 4,000 yards, and no hits
were obtained.

3. During a considerable portion of the time in the area
the BAYA was assigned reconnaissance duty in connection with the in-
vasion of the PHILIPPINE ISLANDS.

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

5. No damage was inflicted upon the enemy.

0940    Liberator circled at about two miles and sent us a
        contact report on four AOs and three escorts hug-
        ging Cape Padaran. Commander F. G. SELBY exchanged
        greetings and requested that we send this contact to

        versed course.
2045    Received message from search plane giving position of
        a contact in very southern corner of our area. Set
        course at four engine speed to close.
2110    GUAVINA insisted that plane contact was GUAVINA. Re-
        quested number of ships in plane's contact but could
        not get a reply.
2120    Plane departed due to low fuel.

0440 SJ radar contact at 33,000 yards, bearing 340° T.
     (Plane Contact No. 15). This was a plane because of
     the large change of true bearing. Closest range
     16 miles.
0900 Received contact from search plane of 1 Sugar Able,
     1 DD, and 1 DE, 100 miles north of BAYA. Could
     not reach this target. Relayed message to FLOUNDER
     and HOE and received receipt. Plotting this con-
     tact showed him to be the same contact by the search
     plane of 2045 last night. This valuable target
     passed 30 miles to the east of BAYA during the night
     and according to our Jap night planes. This has
     been a very bitter pill to swallow; to realize that
     a fine fat target slid by because we did not put
     our faith in our aviators.
1200 Lat. 12-24 N., Long. 110-10 E.; 139 miles, 725 gals.
2140 Made rendezvous with HAMMERHEAD and exchanged in-
     formation by megaphone.

25 February.

0307 Sighted first two of five sails. At this time
0610 Made quick dive for periscope patrol. Ahead at 2-1/2
     we had three sails in sight, one deal ahead at 2-1/2
     miles.
0655 Conducting periscope patrol 5,000-7,000 yards off
     Hon Doi, about 14 miles south of Cape Varella. Sea
     oily flat. Slight surface haze. Numerous sails
     in sight and close aboard, at times as many as 12-
     15 in sight at one look.
1013 Exchanged greetings with two Chinamen at about 40
     feet in low power. Don't know which of the three
     of us was the most surprised.
1200 Lat. 12-39 N., Long. 109-31 E.; 123 miles, 600 gal.
1332 Sighted Liberator on southwesterly course at 18 mi.
     scouting coast line around Cape Varella. (Plane
     Contact No. 16).
1929 Surfaced. Patrolling into moonstreak at 5 knots.

26 February.

0620 Made quick dive for submerged patrol.
0635 Conducting submerged patrol 5,000-6,000 yards off
     Hon Doi. Nice chop with weather clear. Due to a

1200 Lat. 12-37 N., Long. 109-31 E., 94 miles, 615 gal.
1937 Surfaced. Patrolling coast to prevent anything
     from passing between us and the beach.
0403 SJ radar contact bearing 291° T., range 14,800 yds.
     (Ship Contact No. 9)
0409 Three targets tracked at 12 knots on northerly
     courses hugging coast at about 1,500 yards. Com-
     menced end around at 4 engine speed. It turned
     out to be a mad race to get to Cape Varella before
     our targets. With full moon, dawn breaking in the
     east, and what appeared to be an escort vessel a-
     head at estimated range of three miles, at
0550 Made quick dive to radar depth. Manned Battle
     Stations. As dawn came the escort dead ahead turn-
     ed out to be Perforated Rock. Navigator had check-
     ed this before diving but due to land side lobes
     could not give a definite answer. Three ships in
     sight close to beach with dark background.
0613 Periscope depth. Due to predawn visibility could
     not make out ships distinctly. Closest one went
     by at about 2000-2500 yards resembling a flush deck
     PC boat with single gun mount forward. Held fire
     due to size of target.
0654 Secured from Battle Stations. As visibility in-
     creased, at least one target was identified as a
     possible PF of the DE UN-2 class. At no time were
     there any indications of heavy screws or a large
     ship. At this time the range to Cape Varella Light
     was about 5000 yards with all features plainly visi-
     ble and every indication that it was inhabited.
0730 Sighted two Pete type planes at 8 miles (Plane Con-
     tact No. 18).
0930 Conducting submerged patrol 5,000 to 7,000 yards off
     Hon Doi.
0825 Sighted Betty type plane at 10 miles (Plane Con-
     tact No. 19).
1100 Sighted Betty type plane at 6 miles (Plane Contact
     No. 20).
1200 Lat. 12-41 N., Long. 109-32 E., 103 miles, 1235 gal.
1432 Sighted smoke on the horizon bearing 014° T.

     tact (Plane Contact No. 25).
0321 Received orders from HAMMERHEAD to patrol C-3 south
     at discretion. At this time we were in the south
     east corner of our area. Decided due to distance

1416 Surfaced.
1900 Patrolling coast on north-south headings about 6 -
     8 miles off the beach.
2020 Sighted bright glow bearing 180° T. about off Cam-
     ranh Bay. Appeared to be a ship burning. Lasted
     for about 7 minutes.
2023 SD radar contact at 9 miles (Plane Contact No. 27).
     Had APR contact since 2003 at 155 MC being keyed.
2025 Made quick dive. Plane closed to 3 miles.
2054 Surfaced.
2216 APR contact on 202 MC at 900 PRF. Appeared to be
     manually operated rotating antenna due to irregular
     sweeps. Best bearing was about 50-230° T. but this
     was not accurate due to rotation of antenna. This
     was about the correct bearing for Camranh Bay which
     was about 20 miles south of us.
2220 SD radar contact at 11-1/2 miles (Plane Contact No.
     28). APR contact at 158 MC and 900 PRF being keyed.

0426 SJ radar contact bearing 345° T., range 7650 yds.
     Echo very weak (Ship Contact No. 11). At this
     time did not believe echo ranging was coming from
     this target. Resumed closing echo ranging at 4
     engine speed. Passed contact at 1500 yds. Not
     sighted definitely.
0450 Slowed to listen. Weak echo ranging now bearing
     215° T. on same bearing as ship contact No. 11.
0511 Held war pow wow. Decided to eliminate Joe. Man-
     ned Battle Stations.
0530 Tried to pick up target at 3,000 yards from
     bridge. SJ having difficulty lobing on weak pip.
     Decided to let Joe survive for larger game. This
     contact was later proven to be a small sail during
     morning twilight. Secured from Battle Stations.
0615 Made quick dive for periscope patrol 5,000-7,000
     yards off Hon Doi. Heavy surface fog. Visibility
     2 miles and less. Sea oily flat.
0945 Surf noises or possible screws at 285° T. Visi-
     bility 2,000 yards. Nothing in sight.

1958 SD radar contact at 8 miles (Plane Contact No. 33).
     Had full strength signal on SPA at 155 MC.
2001 With range closed to 4 miles, made quick dive.
2013 Surfaced. All clear except for full saturation
     signal on SPA at 155 MC which was lost about half
     hour later.
2030 SD radar contact at 9-1/2 miles (Plane Contact
     No. 34). Contact faded out at 12 miles.

0030 Surfaced.
0042 Sight contact on a properly marked hospital ship
     bearing 152° T. range about 30,000 yards (Ship
     Contact No. 13). This appeared to be a fairly large
     ship, yet the SJ radar could not pick up a pip until

0045 about 15 minutes later at 19,000 yards even while
being coached on by bridge bearings. The pip at
this time was mushy and indistinct.
SD radar contact at 8-1/2 miles (Plane Contact No.
36). Lost contact at 12 miles.

0120 SJ radar contact at 16,000 yards bearing 255° T.
(Ship Contact No. 14). Two sets of echo ranging on
same bearing.

0145 Put 4 Main Engines on propulsion and called away the
Battle Stations Tracking Party.
Convoy appeared to consist of two heavy units with
the smaller on the larger's port quarter at about
600-1000 yards with two to four escorts. Main target
tracked on northerly courses, coast hugging at 12
knots. Two large targets were tracked out to 17,000
yards giving good returns.

0155 Picked up radar interference from target group on
SJ. This appeared to be 10 CM radar of a rotating
antenna. During the entire approach, had contin-
uous APR contact from moderate to full saturation on
153-155 MC. This was believed to be from Jap search,
radar equipped planes. Up until this time, we had
avoided four sailboats on the surface with ranges
from 3,000 to 1,500 yards. Night was bright moon-
light with a light surface fog next to the beach.
Sea flat calm.

0220 Manned Battle Stations.

0230 With APR contact at full saturation, heavy radar
interference on SJ steady on us, three sailboats
within 1,500 - 3,500 yards, three escorts signal-
ling furiously by yardarm blinker, and three ships
in the target group visible from the bridge with
visibility conditions against us; made quick dive to
100' depth.

0250 Came right to 110° starboard track. Two sailboats
within 1000 yards and visible through periscope.
Two escorts continued to signal by yardarm blinker
but were still indistinct through the periscope.
The main target could not be picked up through the
periscope. SJ radar was having a hard time keeping
correct target as all ships were closely
grouped and the land background added to the muddle
on the scope.

0255 With TDC checking perfectly with Radar and Plot,
decided it was now or never. Shifted for low power
shot.

0257-30 Commenced firing a full six torpedo salvo with all
torpedoes set on 5 feet using a 1-3/4 knot speed
spread with a range of 5,900 yards and an estimated
torpedo run of 7,025 yards.
0258-28 Completed firing. Commenced swinging right with
full rudder and dropped down to periscope depth.
0304-10 Heard and observed one hit followed by an
audible and observed hit 9 seconds later. When the
first hit the target appeared to catch on fire from
stem to stern. The second hit caused an explosion
that completely filled the field of the glass in
low power. This explosion and the result was so
great that I could not believe I was in low
power. The light of the fire illuminated the area
as if by sunset. The whole face of Cape Varella
was as bright as day, and the lighthouse was also
as if illuminated by a searchlight with all details
and details distinct. This ship was hit about 1500
yards east of the lighthouse. One Chidori class DD
was boldly silhouetted against the fire at a range
of about 4000 yards. Two other escorts were dimly
in view, two being less than 1,000 yards. This was
a terrifying, but beautifully satisfying picture
with fire and flame all over the ocean and reaching
a least height of 600 feet. Called all hands in the
Conning Tower a look. No details of the target
were observed due to the heavy fire. Just after
the second hit when the hull was outlined, it was
get was estimated to cover 1/5 of the field which
gives a target length of 530 feet. The initial
range of the target picked up against a dark back-
ground in comparison to the range at which the large
target was hit, together with the large number of
leads to the belief that this tanker was a large
0305-40 Heard two definite torpedo hits followed 10 seconds
by another. Nothing could be seen beyond the ori-
ginal target due to the enormous fire. The positive
that these were hits in the far ship. These times
were correct and were impossible for torpedo runs
into the beach. This is further borne out by the
report of one of our planes of a beached tanker the
day. This same message reported the following
ing off Cape Varella.

     During this time and three escorts alternately ping-
     ing and listening with intermittent screws.
0552 Lost screws and echo ranging.
0652 At 60 feet for a look. All clear except for dirty
     red flames and billowing black smoke rising 2000
     feet on the bearing of our attack. Sea
     flat with surface fog next to coast.

0710 Passed within 2500-2800 yards of burning tanker of
     attack of 4 March. Ship was still burning nicely
     with a fair column of black smoke. Could make out
     no definite part of the ship due to the smoke and
     flames. Believe that she is sitting on the bottom
     in 20 fathoms of water with about 30 feet of the
     bow just visible, 1500 yards east of Cape Varella
     Light. Took pictures.

     SPA contact at 205 MC and 900 PRF. Unit radar ap-
     pears to be rotating, at times manually trained,
     with signal strength one to full saturation. Placed
     our faith in the simple assumption that this is a
     early warning aircraft radar.

        interference to the south and BERGALL's to the north.
        Sent contact report by WOPACO.
2335    Passed floating mine at about 400 yards to port.
        (Lat. 11-51 N., Long. 109-19 E).
2355    Target plainly visible clear of left tangent of land
        at about 11,000 yards. Identified as warship.
                                                              21 March.
0000    Made quick dive to radar depth on target's esti-
        mated base course 1600 yards off beach in Badai Bay
        5 miles north of Camranh Bay. Sea flat calm. Visi-
        bility excellent. Bright moonlight with moonset at
        0107.

0003 Exchanged calls by SJ with BERGALL. BERGALL wanted
to chit-chat by SJ. Had a hard time trying to con-
vince my old professor in the BERGALL that we were
right in the beginning of the attack phase trying to
put into practice a few of his teachings.
0007 BERGALL convinced. Finally got SJ 'operator back on
the target. Our 1-A Radar Tech has just learned the
Morse Code and gets a greater kick out of sending
than tracking a target.
0013 Came right to start opening the track. This was a
planned storm tube shot as we were all anxious to re-
move the cherries from the after nest which had not
been fired since commissioning.
0022 Target fairly visible through periscope against
dark land background. Target zigged 15 degrees to-
ward. Commenced opening the track at standard speed.
0031 Target zigged back to base course leaving us 2500
yards from the track instead of planned 1000-1500 yds.
Dropped down to 45 feet.
0034-47 With TDC and Plot in perfect agreement, all torpedoes
set on 4 feet, 90 starboard track, gyros rolling up
on 180 range 3100 yards, commenced firing full three
torpedo salvo using a 1-1/2 knot speed spread.
0036 Down to periscope depth.
0037 Target entered left edge of moon streak and definitely
identified as a man of war: a MATSU class DD with a
slender stack well aft under the mainmast and large
open space between it and the bridge structure and
a single gun house forward. By periscope formula
this ship measured to be 290-295 feet long.
0038-10 Observed and heard one hit in target amidships.
Hit was a good solid explosion with a grey flash and
a towering mushroom of black smoke followed by a
small orange fire. Sound reports no screws.
0040 Surfaced. While taking SJ sweep at 40 feet, SJ had
a weak echo at 3700 yards on the bearing of the
target when hit. By the time the watch got to the
bridge the target had faded from the screen and
nothing was in sight from the bridge except a high
cloud of black smoke.
0041 Commenced opening scene of attack. Wanted to take
a good close look but decided it was not worth the
risk. In twelve war patrols, this is the first at-
tack that the commanding officer has been aboard
that something has been gotten for nothing.
0136 Patrolling coast to the south at 7-5 miles at 5 kts.

0140 Received orders from ROCK to conduct submerged
patrol north of 11-30 N.
0153 APR contact on 156 MC strength 3-5. Commenced key-
ing SD. Had had numerous APR contacts of less
strength during entire night.
0154 SD radar contact at 11 miles (Plane Contact No. 58).
0156 APR contact at 11 miles.
0250 APR contact strength 3-5 on 156 MC. Commenced key-
ing SD. Had almost continuous APR contact with
this plane since the last SD contact.
0255 Lost contact at 9 miles coming in (Plane Con-
tact No. 59).
0259 With range closed to 4 miles, made quick dive.
0316 Surfaced. All clear, except APR with signal
strength 2.
0405 SJ radar contact on BLENNY bearing 297° T. range
8000 yards.
0450 SJ radar contact bearing 275° T., range 16,500
yards, and at the same instant sound reported echo
bearing 280° T. (Ship Contact No. 18).
Contacts had just rounded Hon Do leaving Phang-
Rang Bay.
0455 Now have one large and two small targets by SJ and
two sets of echo ranging. Called away Battle
Station Tracking Party and commenced tracking at 4
engine speed.
0500 Decided we had just enough darkness to get in a
surface attack before dawn. Sent contact report by
COPACO.
0506 APR contact up to strength 3. Commenced keying SD.
0507 APR radar contact at 5 miles (Plane Contact No. 60).
0510 APR contact strength 5. SD range 4 miles.
APR contact blocking out entire SPA scope. SD
range 1 mile. Made quick dive to 120 feet.
0512 Surfaced. Commenced planing up to 60 feet.
0520 APR contact strength 1-2.
0525 With BLENNY between us and the convoy had to give up
the plan of a surface attack. Do not believe that
she has contact yet due to side lobes of land.
0535 APR contact at 152 MC (aircraft) and 156 MC (land-
based) both with full strength of 5 and blocking
out entire SPA scope and continued so until diving.
We are so close to the beach that the land echos
block out the entire SD screen.

0600 With radio reporting that if either signal strength
     (0a) gets any stronger they would blow out the SPA scope,
     (0b) all targets tracking nicely on northerly courses at
     8-10.knots using a modified zig plan coast hugging,
     with dawn breaking fast in the east with a cherry red,
     (0c) 00D dancing from one foot to the other claiming
     he was getting sun burned and with Hon Chut light
     plainly visible; made quick dive 3,000 yards off Mui
     Davich at the entrance to Camranh Bay.
0605 Sighted one DE-UN-1 class and 1 SC-S-1 class Special Duty SC
     visible through periscope with another possible small
     target close inshore.
0625 No other targets in sight or on sound.
0630 The DE kept giving us small port and starboard angles
     on the bow as he came around Mui Davich. It began
     to look like a down the throat shot so made ready
     all tubes. Decided to give the DE the stern tubes
     to save the bow tubes for anything else coming up a-
     stern.
0638 The DE changed course to the left to go around Mui
     Davich giving us a nice shot. Commenced swinging
     for a starboard track.
0645-52 With target definitely identified as a DE-UN-1, with
     a camouflage job in black and green exactly similar
     to that of the U.S.S. ANTHEDON, TDC checking beauti-
     fully, 90 starboard track, gyros rolling up to 180,
     all torpedoes set on 5 feet, range 2200 yards; com-
     menced shooting a full three torpedo salvo "dream
     shot" aft, using a 2 knot speed spread. To about
     3000 to 4000 yards astern of the DE giving us a
     good angle on the bow.
0646-18 Completed firing. Lowered the scope to wait for the
     hits.
0647 Sound reported all torpedoes running. Two running
     erratic and one tracking 30-40 degrees astern of the
     target. Checked target through periscope during the
     normal run of the torpedoes and he continued on the
     same course.
0648 Sound reported one torpedo coming in. Tor-
0650 pedo reported going up port side. Torpedo reported
     going up starboard side. JP reports torpedo screws
     all over dial.
0708 Trying to get set up on a target. At this time we
     were 3500 yards from the beach. Only ship in sight
     was one Sugar Dog very similar to SHINKYO MARU (ONI
     208-J Miscellaneous Coastal Freighters and Tankers).

the SC-S-1, and a second small Sugar Dog of about
500 tons not very distinct against the land back-
ground. Set up on SHINKYO MARU but did not con-
sider him worth a torpedo.
0712 SC seemed to be coming by nicely at about 1500
yards with a 50 degree angle on the bow.
0716 SC displaying flag mast with the four pennant at
the top followed by three flags giving us a 25°
angle on the bow.
0717 SC giving us about 10° angle on the bow. Did not
believe that he had us sighted as he was not ping-
ing on us.
0718 SC still showing a 10° angle on bow at about 900-
1000 yards. Commenced casing down to 200 feet.
Rigged for Depth Charge and Silent Running. Still
not convinced that SC had seen us, but was prob-
ably coached on by a plane and smoke float. Rigged
in one sound head.
0724 At 200 feet. SC passed directly overhead with
screws heard distinctly in all compartments. Wish-
ing that this was just another drill off Rottnest
Island. Eased on down to 220 feet.
0724-30 First of 21 depth charges, much too close. Esti-
mated on either side of bow and above at about 200
feet. Ship bodily knocked from 220 feet to the
bottom at 270 feet. These really jarred the core
of my teeth. Great showers of cork and paint chip-
pings. All normal lights knocked out. Light bulbs
shattering like icicles on an autumn morning.
Much rattling of deck plates and loose gear flying
around.
0725 Conning Tower hatch fluttering like a check valve.
Took two complete turns on it. Navigator calmly
combing the light bulbs out of his hair as he
peers through the gloom to see if the Control Room
is still there.
0726 All stop. Laying on the bottom and taking it.
One close one blew the door between the Engine
Rooms closed. FER reports a bad water leak. AER
dogs door down. AER reports a bad air leak. FER
throws the locking bar across the door. Both rooms
believe the other one doomed.
0728 Control reports red lights on three hatches and
Fuel Ballast Tank vents. Compartments re-
porting sea valves backed off from one to three
turns. Forward Room reported 5 bent gyro spindles.
Only able to get one out before first depth charge
went off.

0730        As the ship rolled and worked on the bottom there
            were loud creaks and groans heard throughout the
            boat. Port sound head was evidently ruptured it
            gradually became so noisy that it was of no further
            use. Forward Room reported shaft sprung but managed
            to get it rigged in.
0732        JP reports loud air leak aft. Secured all air.
0735        Still taking it. C.O. wishing that he had gone to
            church the last Sunday in port.
0740        Last of 21 depth charges. Two sets of pingers work-
            ing all around us and over us. Pinging right on most
            of the time on short scale. JP estimated ranges 1500
            to 800 yards.
0800        Decided to try a Mark 27 as range was well under
            1000 yards. Trouble getting outer door open.
0815        Target going away.
0829        Lost screws and pinging. Possible screws still at
            2800 relative.
0849        Commenced pumping from Auxiliary to sea.
0855        Having shifted 4000 lbs., broke loose from bottom.
            Commenced coming up to 60 feet.
0911        Periscope depth and all clear except to the astonish-
            ment of the C.O. we were headed directly into Camranh
            Bay and only 3500 yards from the entrance leaving
            Mui Davich abeam to port. This was our possible
            screws at 280 degrees relative. Steering 141° T. by
            gyro. Gyro checks showed master and repeaters check-
            ing. While on the bottom the head shifted about 40
            degrees to north and south of east. Quick check
            showed master was not settled on the meridian and the
            follow up system out. Actually steering course
            320° T. Changed course to east and commenced open-
            ing the coast.
0924        Secured from Battle Stations, Depth Charge and Silent
            Running.

0500 APR contact with full saturation signal on SPA on
156 MC. This land based radar has been manned
each morning at 0500 and on nights that traffic
is on the prowl. Closing thecoast to dive daily,
it has given us full saturation signal which at
times leads us to think he is looking down our
throat. This is believed to be an early warning
aircraft radar.
0547 Made running dive for periscope patrol, 4,000-
6,000 yards off Mui Davich, Hon Don area.
Sea 1. Visibility good.
1200 Lat. 11-45 N., Long. 109-15 E.; 102 miles, 1050 gal.
1319 Sighted B-24 at 4 miles over Phangrang Bay (Plane
Contact No. 61).
1400 About 15 percent of the crew sick; suffering from
dizziness, nausea, and general abdominal discomfort.
Cause undetermined.
1958 Surfaced. Patrolling coast at 5-6 miles. Bright
moonlight.
2200 Unable to copy VIXO. Signal strength 1 to 2.
2315 Exchanged calls with BLENNY by SJ radar and asked
if she could copy VIXO. She reported that she
could, signal strength 2-3.
2330 Made rendezvous with BLENNY. Exchanged copy of
strip cipher arrangement for copy of Baker sched-
ules. Exchanged information by megaphone.
Received orders from the BLENNY had orders to
depart area on the 24th and proceed to Subic Bay
for refit. Alsozoomies sighting of convoy of two
large tankers, two small marus, and two escorts
at 0830 on the morning of our last attack just
6 miles to north of the attack. The two tankers
must have joined from Camranh Bay as there was no
indication of them during an hour of radar track-
ing nor during the periscope approach.

23 March.

0059 Received orders from Pack Commander to conduct
submerged patrol close inshore north of 11-30 N.
0100 Had very heavy 10 CM Jap radar interference on
SJ which lasted for about 5 minutes coming in all

The weather agreed in general with the Sailing Directions,
H.O. Vol. 125 and was normal expected weather for the North-
east Monsoon. Average temperature 75° F. Wind consistently
from 025° T. between latitudes 11 N and 13 N near coast of
Annam. Average velocity 10 - 15 knots. Four days of flat
calm (Feb 24 - 28) were accompanied by dense surface fog
within 2 miles of the coast. Average sea state 0 - 1 during
latter part of February; 1 - 2 during March.

(D) TIDAL DATA.

The current consistently followed the coast in a south-
erly and southwesterly direction. The average current near
the coast was 1-1/2 knots; beyond the 100 fathom curve one
knot. The currents are affected by the wind, increasing to
2 or 3 knots near coast in state 3 sea and 15 - 20 knot
winds. Subsurface temperatures exceeded surface tempera-
tures by 1 to 3 degrees F.

TARGET DATA DAMAGE INFLICTED

Description Convoy consisting of two heavy units and three
or possibly four escorts. Coast hugging with
the two major targets in line of bearing of
about 045°-225° relative, distance 600-1000
yards. All escorts to seaward. Using a modi-
fied zig plan to conform with coast. Contact-
ed by radar rounding Hon Doi. Sea flat calm.
Bright moonlight. Visibility good with ex-
ception of surface fog next to coast. By
periscope formula target length was 530 feet.
Ship Sunk 1 Large Sugar Able (AO) 10,000 tons (EC).
Ship Damaged 1 Medium to Large AK (EU).
Damage Determined by Ship Sunk: Observed and heard two hits in
target. With resultant fire and explosion
ship was doomed. Observed to burn for three
days after attack. Aviators twice reported
this ship burning. Observed and took pictures
of fire three days later from 2500 yards.
Nothing definitely visible of ship except for
smoke and fire. Sunk in 20 fathoms of water
1500 yards off Cape Varella.
Ship Damaged: Heard two properly timed de-
finite torpedo hits. Results could not be
observed due to enormous fire of No. 1 tar-
get. Aviators reported the following day in
same message that AO was reported burning
that an AK was down by the stern and appar-
ently beached at 13-28N and 109-13E which is
about 32 miles north of the attack. This
ship had not previously been reported by our
daily reconnaissance flights. See also En-
closure (C).

TARGET DRAFT 25-30 feet ESTIMATED COURSE 000° T.

FIRE CONTROL AND TORPEDO DATA.
Type Attack This attack followed a deliberate hour and
half tracking in which the target course
and speed were accurately determined. At-
tack was carried out at radar depth with
continuous radar bearings and ranges. This
was a low power shot with all torpedoes set
on 5 feet using a 1-3/4 knot speed spread
which at the torpedo run gave a 758 yard
spread. Used Uy=90 yards. Large torpedo
run was due to being forced down early.

TARGET DATA DAMAGE INFLICTED

Description This contact was a single ship picked up by
            radar rounding Hon Do leaving Phangrang Bay
            using a modified zig plan coast hugging,
            speed 12-13 knots. Target identified as a
            man of war of the MATSU Class DD. Long and
            slender. Had a thin stack well aft from
            mainmast, large open space between it and
            bridge and a single gun house forward with
            an AA platform between it and the bridge.
            By periscope formula the length was 290-295
            feet. Could not make out a definite stack
            abaft foremast but there was a structure
            there, either a stack or a tall search-
            light platform. Sea force 0-1. Bright
            moonlight with land background.
Ship Sunk 1 MATSU CLASS DD, 1,000 Tons (EC).
Damage
Determined by Observed and heard one properly timed tor-
            pedo hit amidships. Sound reported screws
            stopped. In surfacing two minutes later at
            40 feet SJ had a weak echo at 3,700 yards
            but by the time the watch got to the bridge
            the pip had disappeared and nothing was in
            sight but a heavy black cloud of smoke.

No mine laying or mine sweeping activities by the
enemy were observed.

On 20 March at 2335H one floating mine was observed
off the entrance to Camranh Bay (Lat. 11-51 N., Long. 109-
19 E). This mine appeared to be of the moored type, spher-
ical in shape, with characteristic horns.

(J) ANTI-SUBMARINE MEASURES AND EVASIVE TACTICS.

Following the attack of 4 March off Cape Varella
evasive tactics were of the normal run consisting of going
as deep as possible consistent with the bottom in order to
keep the charges above, maneuvering to keep the escorts
astern, and fish tailing away from scene of attack to deep
water. It is believed that the escorts never had positive
contact although they echo-ranged in our vicinity for three
hours, possibly to keep the submarine down. This primary
depth-charging was the "saturation" type, rolling them off
rapidly over a large area which proved very ineffective in
this case.

The depth-charging of 21 March off the entrance to
Camranh Bay was very close and severe. Evasion consisted
of remaining on the bottom in 270 feet of water and mud
after being knocked there by the first pattern of charges.
The escorts original attack followed either the sighting
of the scope or after being coached on by a plane and a
smoke float. The latter is believed to be correct as the
escort did not echo-range in our direction preceding the
initial attack. It is also true that he may have played
the game smarter than we did. This attack was also a
"saturation" depth charging. During the hour of echo-
ranging by the escorts - most of the time on short scale -
although they worked all over and around us within 1500-
800 yards and pinged consistently in our direction, they
never positively had contact.

(K) MAJOR DEFECTS AND DAMAGE.

It is impossible to believe that the boat could
come through the jarring depth-charge attack of the 21st
of March with such a small amount of major damage. The
minor damages were of little importance and were repaired
or restored within three days. The major damages are as
follows:

1. Pronounced knock in port reduction gear.
2. Noisy main motors.
3. Port sound head (QB) damaged beyond use.
4. Both periscopes filled with trash.
5. Master and Auxiliary Gyros knocked out.
6. Five bent gyro spindles.

(L) RADIO.

There has been considerable Jap traffic on the WOPACO
frequency, but it has not been enough to interfere with our
circuit work. A number of messages have been received
without proper authentication and obviously sent by the
Japs to either lead a boat to a rendezvous or in an en-
deavor to confuse our submarines.

There has been little jamming. Most difficulty in
receiving VIXO has been due to weak signals from the
transmitting station and atmospheric conditions.

For further details see Enclosure (D).

(M) RADAR.

The performance of the SD and SJ have both been
eexcellent with no actual time lost due to either one being
out of commission. No major repairs have been necessary
other than normal tube replacement. The credit for the
excellent operation and performance of this gear goes to
FAST, Herbert, #654 39 17, RT1c, V6, USNR.

(O) DENSITY LAYERS.
    No density layers were observed or found on this
    patrol.

(P) HEALTH, FOOD, AND HABITABILITY.
    The food has been well prepared and the menu well
    balanced. The health of the crew has been good; the
    sanitary and living conditions have been good throughout
    the patrol.

    The cause of the mass sickness of the 22nd, 23rd,
    and 24th of March is still undetermined. The symptoms
    displayed were as follows: dizziness, nausea, abdominal
    discomfort, diarrhea, and vomiting.

    The possibility of food poisoning has been ruled
    out as no single item of food was eaten by all afflicted.

    The causative agent has not been determined. How-
    ever, on the morning of the 21st, the ship was exposed to
    a rather jarring depth charge attack and it is believed
    that whatever the etiology it resulted from this.

    Numbers 1 and 2 Fresh Water Tanks have been se-
    cured to minimize the possibility of contaminated water.

    Because of the fact that the afflicted officers and
    men suffered most during the end of a submerged run, it
    is suspected that there may have been a slight presence
    of stibine or arsene gas.

The state of training of both officers and men was ex-
cellent and left nothing to be desired. The performance of
duty under combat conditions was very heartening. As long
as our men continue to react to emergencies, display the
intelligence and guts found on this patrol our Navy should
have no fear in continuing to carry the war to the Japs.

The caliber and quality of the men received aboard
this patrol were exceptionally high. The percentage of non-
qualified first run was exceedingly low. The efficiency of
the Lookout Watch has been nothing but phenomenal.

In the past the policy has been developed to transfer
one quarter of the crew at the end of each patrol. This
largely grew out of the requirements for new construction
and the desire to give the men who had made several long and
strenuous patrols a rest. Within the past year this policy
has been rigidly enforced and adhered to.

It is believed by this command that this policy at
present is being violated by the refit activities to the
extent that it is not accomplishing its intent.

When putting into Fremantle for refit last August,
four men who were transferred to the Relief Crew were ac-
tually sent to sea before their previous ship had gone to
sea. On this patrol we have aboard three men with whom I
made the BERGALL'S second run. These three men were trans-
ferred to this command less than a month after their return
from the previous patrol.

Since the submarine normally expects to return to the
States for an overhaul at the end of five or six patrols,
this policy of transferring a quarter of the crew definitely
handicaps the submarine by throwing into the crew a large
number of men who must be worked into a smooth running
organization. In the majority of cases the men positively
do not want to leave the ship in which they have adjusted
themselves, only to be sent to sea in another submarine.
In being transferred the man looses his chance of riding
the boat back to the States. New Construction demands at
present are very small in comparison to a year ago.

(Q) PERSONNEL (Cont).

It is believed that the number of men to be trans-
ferred at the end of a patrol should not be set at any
block number but rather left to the discretion of the com-
manding officer. About one eighth of the crew is a more
reasonable number and will allow a sufficient number to
weed out the undesirables and also to leave in those that
need a rest due to a war fatigue.

One of the finest and most popular means of entertain-
ment while on patrol is the showing of motion pictures.
This is definitely a tension relaxer and very excellent for
the morale of the men.

This ship has had a 16 MM motion picture projector
aboard since commissioning and during three war patrols,
but no films. During this period all efforts to procure
films in the States, at Pearl Harbor, and at Fremantle have
met with failure. Although twelve (12) prints were avail-
able in a film pool at SRU, Fremantle, the captain of the
base refused to give the BAYA a single film because we had
none to trade.

The Army has realized the value of this type of enter-
tainment and has a large supply of films available even at
their most advanced bases. It is hoped that our Navy and
especially the Submarine Service will soon follow suit and
make available approximately ten programs for each sub-
marine per patrol.

These statements are not made in any tone of accu-
sation, but rather are an outgrowth of over two years of
effort to procure films with diminishing success.

(V) REMARKS:

Much native sailboat traffic was encountered
during this patrol in Areas C-3 to 4 close in to the
coast. Few were the times that they did not interfere
with working the coast both at night on the surface and in
the day submerged. Traffic varied with the weather to
a marked extent. It was not unusual to have 6 to 10
sailboats in sight on each one minute look. The average
was about 10. During one look forty-seven (47)
sailboats were counted. This traffic was not molested
hoping for better game, and in the belief that it was
mostly native traffic.

Japanese coastal shipping was highly disap-
pointing. There was no small maru or sea truck traffic.
All shipping encountered was coast hugging following the
beach within a mile and always inside the 10-20 fathom
curve. All traffic stopped in the dark of the moon and
immediately picked up as the moon became bright. This
shows that the Jap definitely respects our night sur-
face patrols which he lays to our PT boats. All of our
coast submerged work was conducted within 2-3 miles of
the beach. With 6 feet of scope the surf was visible
most of the time. This may have been too close but it
was our intent that nothing should pass between us and
the beach unobserved.

Camranh Bay appears to be dead. Nothing was
observed to enter or leave it, and we kept a close watch
on it for almost three weeks. No regular patrol operates
at its entrance. No activity was noted there at anytime,
air or otherwise. We looked in numerous times from less
than two miles.

In dealing with Jap radar equipped planes the
following procedure was used: The SPA-1 scope was
marked off vertically into five equal divisions, 5 being
full saturation signal. A close watch was kept on the
APR-1 and SPA-1. When contact was made, we endeavored
to determine the type radar from all available infor-
mation keeping the bridge informed of the type radar
and signal strength. It was planned to key the SD when
the signal strength reached 5, but practice showed that
this often allowed the plane to get within 3 to 4 miles.
We finally settled on the following procedure: When the
radar was identified as airborne and reached a signal
strength of 3, the SD was keyed three times (2 seconds
in each minute). At this time we believed that the

plane was somewhere with in the ranges of 3 to 10 miles.
If no contact was made, the SD was secured until the
signal strength reached 5 at which time the SD was keyed
until the contact was developed or the APR signal greatly
diminished. When the contact was developed, either by SD
or SJ, we slowed to reduce the wake and maneuvered to place
the contact astern. We had very good success in using
this procedure.

The SJ was keyed only during tracking and when
we had Jan 10 CM radar on the SJ screen.

It is believed that the cooperation between our
shipping spotting planes and submarines could be markedly
improved if the planes would set up on 4475 KC or VHF.
get the VHF. On numerous occasions when we had B-24's in
sight at from 7 to 25 miles all attempts to call the plane
by light, HF, and WOPACO frequency was of no avail. VHF
is very weak and ineffective. On the other hand planes
were copies on 4475 consistently up to about 200 miles.

1. The third war patrol of the U.S.S. BAYA, the first for her
commanding officer as such, was conducted off the coast of INDO-CHINA and
comprised a period of forty-six (46) days of which thirty-eight (38) were
spent in assigned areas. BAYA (SS318) with HAMMERHEAD (SS364) formed a
Coordinated Attack Group with Commanding Officer HAMMERHEAD as Officer in
Tactical Command. On 6 March this group was dissolved and BAYA joined BECUNA
and BLENNY to form Pack Number 2 with Commanding Officer BECUNA as Officer in
Tactical Command.

2. Worthwhile targets were scarce, although the area coverage and
coast patrol was thorough and contacts made were aggressively developed, with
the result that in three attacks twelve torpedoes were fired, to sink one
large tanker, one destroyer, and damage one large freighter. Many patrol
boats were encountered, and surface patrolling was consistently hampered by
enemy radar equipped search planes; the Commanding Officer utilized his
SPA-1, APR-1 and SD equipments to the best extent, which no doubt attributed
to the BAYA's success in avoiding bombing from that source. Contacts with
our own planes were frequent, but poor communications hampered efficient
coordination. Two-way communication was occasionally obtained, and in a few
instances planes reported contacts, but at such positions that interception
was out of the question. With each succeeding month finding enemy traffic
diminished and lines of communications narrowed, it is imperative that mutual
exchange of information between our planes and submarines be improved.

3. A new anti-submarine measure was encountered on 3 March off
HON DOI (due south of Cape VERELLA) when weak echo ranging was picked up, and
SJ radar contact subsequently made at 7,650 yards. The target was not
definitely sighted at 1500 yards, and the Commanding Officer wisely refrained
from expending his torpedoes. Morning twilight permitted this contact to be
identified as a small sail boat, fitted with supersonic equipment. Native
sailboats were a constant source of interference close inshore, both day and
night, even during submerged attacks. The BAYA was fortunate, however, in
that only one mine was sighted, which is contrary to the experience other
submarines recently have encountered in that area.

                                                                -1-

Subject: U.S.S. BAYA (SS318) - Report of Third War Patrol -
         Comment on.

         1. The Third War Patrol of the BAYA was the first under
the command of Lieutenant Commander B. C. JARVIS, U.S.N. BAYA
patrolled in the SOUTH CHINA SEA in the areas off the INDO-CHINA
coast.

         2. On 4 March, BAYA made an excellent submerged moon-
light attack on two escorted ships. Six torpedoes were fired and
four hits were made. As a result of this attack a medium tanker
was sunk and a large AK was set afire, beached, and destroyed. On
21 March BAYA made a submerged night attack on a MATSU DD and one
hit sank this target. The same morning BAYA attacked a DE, but
several erratic torpedo runs resulted, and no hits were made.

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

         4. The Force Commander congratulates the Commanding
Officer, Officers and Crew of the U.S.S. BAYA upon this smart and
well conducted patrol during which the following damage was inflicted
upon the enemy:

                                        S-U-N-K

down both sides of the periscope shears and overhead.
4.7 inch appeared to be common and fused as it
was ricochetting alongside and over the stern as well
as bursting overhead which was thought at first to be
star shells.

2309 With range at 1150 yards commenced firing three torpedo
salvos down the throat shot.

2311 Target presenting alternate port and starboard angles
on the bow apparently avoiding possible torpedoes and
bringing his after guns to bear.

2320 With range about steady on 1700, the second escort at
4,700 yards, the near escort illuminated us by search-
light and began a little accurate gunning. Blew safety
dry. Gave all tanks a five minute blow. Fired No. 10
tube which had been reloaded at near escort.

2325 Range opening to 2100 yards. Escort secured his search-
light and resumed all caliber firing.

2329 Heard and felt six tremendous explosions about 10 seconds
apart which shook the ship violently. Possibly depth
charges in shallow water.

2333 Escort turned away giving us a parting burst with all
guns. Range opened rapidly from 3,000 yards on out.
Informed L.A.G.R.T.O. that we had been driven off by gunfire.

2341 Exchanged calls with L.A.G.R.T.O. and for the first positive
time identified No. 6 as the L.A.G.R.T.O.

2345 Secured from Battle Stations with the range opening
fast. It is nothing short of a miracle that we came
through so much gun fire without a single hit. His
deflection was as consistently on as his range was off.

2215 Proceeded at full speed on end around for port flank
     attack. Keying SJ radar once each minute. Two separate
     10 cm. radar interferences from the direction of the con-
     voy, usually keyed for ten seconds each minute. Occasional
     enemy radar sweeps were made at the rate of 3½ revolu-
     tions per minute.

2240 Making good progress up targets port quarter. Convoy
     has suddenly changed course to his left to 050° T. Con-
     tinued to cross ahead at full speed.

2250 Convoy changed course abruptly to 340° T. These can not
     be zigs. Convoy is obviously alerted by our radar and is
     taking evasive actions based apparently on change of
     bearing of our own 10 cm. radar.

2300 Continuing down convoy's starboard flank to gain posi-
     tion for a 120° track on main group. Convoy has now
     eased around to small zigs on a rough base course of
     050° T. We are using our SJ only 5 seconds each two
     minutes.

2347 Convoy zigging on base course 060° T., speed 9 knots.
     Having sent LIGARTO contact reports almost half hourly
     with no receipt, decided to make the attack alone.
     Manned battle stations.

2358 In nice position on starboard bow expecting zig away.
     Commenced surface approach at 14 knots from starboard
     bow. Night dark with clouds around the horizon with
     occasional lightning. Sea flat calm. All torpedoes
     set on four feet. Nearest escort 1500 yards on star-
     board beam of leading target. Planned for 110-120
     starboard track to fire three torpedoes at each main
     target. There is a chance that we have confused the
     convoy by little use of our own radar.

                               4 May

0010 With target almost 15 minutes overdue for a zig and
     giving us a 55 track decided to fire all six bow tubes
     at the leading and larger target.

0011 With torpedo run of 5500 yards, commenced firing low
     powered shot forward. As No. 3 left the tube the target

targets to turn away completely while near escort turned
towards.

0015 One explosion reported from below. Not seen from bridge.

0030 Pulling away from escort. Decided to try another star-
board flank attack after shaking escort. Manned battle
stations.

0037 Escort still chasing us on port quarter. Main target
group on course 020° T.

0053 Put out RDB and went ahead to open out on escort. RDB
could not be picked up by our SJ and it did not lead the
escort astray. Convoy made radical course change to
the northwest.

0110 Changed course to 020° T. at full speed to shake escort,
get ahead of him, and head in for second attack - pre-
ferably on port flank because of moon.

0118 Moonrise. Convoy has changed course to 320° T. to keep
us astern. Escort is tagging along wide between us and
main group, keeping us silhouetted in bright moonlight.
The Jap 10 cm. radar is too good for us tonight. They
are neither going to let us close or gain a position
ahead for a submerged attack.

0134 Lost contact. Secured from Battle Stations. Changed
course to follow ahead on possible convoy track at slow
speed.

(P) HEALTH, FOOD, AND HABITABILITY.
The health of the crew has been good. There has been no
evidence of vermin or parasitic insects. The general sanitary
condition has been good.
Too much credit can not be given to the Commissary Department
for the high state of morale of the crew. All meals were well
planned, well balanced, and excellently prepared. Both cooking
and baking were outstanding in their own lines. The ice cream
freezer has been enjoyed by all hands and has more than paid for
itself on this run alone.
Movies were shown on this patrol for the first time. Their
value as a means of relaxation and amusement can not be overesti-
mated.
Habitability has been good. The Air Conditioning Plant is
sufficient even in equatorial waters.
There have been no serious illnesses or injuries. The only
battle casualty occurred as follows:
HANSON, W.O. Slc (TM), #762-27-47, USN, while acting as 1st
loader on the 5"-25 cal. deck gun, firing upon an enemy mine,
sustained laceration under the right eye and on the upper right
eyelid. There was no apparent injury to the eye or damaging
effect to the visual acuity. Five sutures were necessary. This
injury was caused by an ejected shell case rebounding off the
life line.

FIRST ENDORSEMENT to
U.S.S. BAYA (SS318) -
Report of Fourth War
Patrol.

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

Subject: U.S.S. BAYA (SS318) - Report of Fourth War Patrol.

1. The Fourth War Patrol of the BAYA under the command of Lieutenant
Commander B.C. JARVIS was conducted in the Gulf of Siam, South China Sea and Java
Sea Areas. Patrol was of 29 days duration of which 23 days were spent on station.
Lifeguard duties were performed on 25,26,28,29 April for strikes on Saigon. Four
days were spent submerged conducting anti-submarine patrol.

2. Torpedo Attack #1 was a night surface radar attack on a two ship
convoy with two escorts. Escorts were equipped with 10 CM radar and knew how to
use it. Fired 2 Mk 14-3 torpedoes from bow tubes down the throat at Sherataka
mine layer escort at a range of 1500 yards. Both missed. Range was closing 1250
yards per minute so BAYA turned hard right to avoid being rammed by escort.
Escort opened fire with (3) 4.7", 40mm and 20mm at a range of 1100 yards. With
range 1100 yards 3 Mk 18-1 torpedoes from after tubes were fired down the throat
at escort. All missed due to radical maneuvers of escort. BAYA reloaded one Mk
18-1 torpedo aft and fired this down the throat at pursuing escort, this torpedo
missed. BAYA was under fire from this escort for 26 minutes without receiving
any damage. The only evasive tactics that could be employed by BAYA was high
speed on the surface as there was only 42 feet of water under the keel.

3. Torpedo Attack #2, twenty four hours later, a night surface radar
attack was made on a same convoy. Six Mk 14-3 torpedoes were fired from bow tubes
at leading medium tanker, torpedo run 5500 yards on a 60 starboard track. While
firing, target turned away and all torpedoes missed.

4. Torpedo Attack #3, was a night surface radar attack on a convoy
consisting of one large Sugar Baker, one medium freighter escorted by a large mine
layer. Six Mk 14-3 torpedoes were fired from bow tubes at large Sugar Baker; 100
starboard track, depth set 4 feet, gyro angles small, run 3900 yards. Three tor-
pedoes hit and target was observed to sink 23 minutes later. Six minutes later
fired 2 Mk 18-1 torpedoes from stern tubes at mine layer escort on a 90 starboard

1. This, the Fourth War Patrol of the BAYA and the
second under the command of Lt. Comdr. B. C. JARVIS, U.S.N., was
conducted with the same tenacious aggressiveness that characterized
the preceding patrol of this submarine.

2. The night surface attack on a two ship convoy pro-
tected by two ten centimeter radar equipped escorts stands among the
more daring submarine attacks of this war in spite of the fact that
it was unsuccessful. The attack was conducted in seven fathoms of
water, the Commanding Officer knowing at the start that he was con-
fronted by two alerted, radar equipped escorts, and that he would
have to outmaneuver both of them to gain an attack position on the
convoy and then, to escape, outmaneuver them again on the surface
since the water was too shallow to dive. Unfortunately the escorts
knew how to use their radars and one of them not only prevented BAYA
from gaining an attack position but maneuvered to avoid a series of
six torpedoes fired down the throat. When the BAYA changed course to
avoid ramming, this escort opened up at 1100 yards range with three
4.7", 40 MM and 20 MM guns and kept the BAYA under fire for 26 min-
utes. During eighteen minutes of this period the range was under
2100 yards.and for about 5 minutes she was illuminated by searchlights.
That the BAYA escaped without receiving a single hit is almost miracu-
lous.

3. On BAYA's second attempt to get this convoy 24 hours
later the escorts outmaneuvered the convoy and themselves to prevent her
from closing on the surface or gaining position ahead for submerged
attack. Six torpedoes fired from long range in low power missed when
the targets changed course during firing.

4. The highlight of the patrol was the complete wiping
out of a three ship convoy composed of a large freighter, medium
freighter and minelayer escort in a beautifully conducted night sur-
face attack in 10 to 12 fathoms of water.in which seven hits were

## The Battle of the Battle of the Labyrinth

The Battle of the Labyrinth, the fourth installment in Rick Riordan's "Percy Jackson & the Olympians" series, is a pivotal moment in the ongoing war between the Olympian gods and the rising threat of the Titans. While the title suggests a single, climactic confrontation within the mythical Labyrinth, the "battle" itself is a multifaceted struggle encompassing several key encounters, strategic maneuvers, and personal challenges for Percy and his friends.

**The Labyrinth as a Battlefield:**

The Labyrinth, a sprawling, ever-shifting maze created by Daedalus, serves as the primary battleground. Its unpredictable nature, filled with monsters, traps, and shifting pathways, makes it a formidable and dangerous environment. The Titans, led by Luke Castellan (possessed by Kronos), seek to use the Labyrinth to bypass the defenses of Camp Half-Blood and launch a direct assault. Percy and his allies, therefore, must navigate its treacherous depths to prevent this invasion.

**Key Encounters and Mini-Battles:**

1.  **The Quest for Daedalus:** Percy, Annabeth, Grover, and Tyson embark on a quest to find Daedalus, hoping he can provide them with a way to navigate or control the Labyrinth. This journey involves numerous smaller battles against various monsters and mythical creatures, each testing their skills and teamwork. These encounters, while not large-scale armies clashing, are crucial skirmishes that shape the overall conflict.

2.  **The Arena of the Minotaur:** One significant confrontation occurs when Percy and his

0125                            Made rendezvous with U.S.S. CAPITAINE (Ship contact
                                  No. 10). It was decided in conversation via VHF
                                  that the CAPITAINE would attack from the north while
                                  the BAYA attacks from the west. Firing of the deck guns
                                  is to commence on receipt of "execute" from the
                                  U.S.S. CAPITAINE. The Sub Chaser will be primary
                                  target.

0152                            "Execute" from U.S.S. CAPITAINE. Commenced firing
                                  with fuzes set on super quick. Range to target
                                  6000 yards, closing.

0154                            Hit in Sub Chaser near stern.

0155                            All ships in convoy are now returning fire. Range
                                  to Sub Chaser 4400 yards.

0155:35                         Another hit in Sub Chaser. The Sub Chaser is firing
                                  a 37mm or 40mm, while the Sugar Dogs are returning
                                  fire with what are apparently 3" deck guns. The
                                  enemy projectiles are not tracer but they can be
                                  heard whistling over the bridge uncomfortably close.

0156                            Shifted to local control at the guns and reversed
                                  course to open range. Guns fired by local spotting
                                  at several of the Sugar Dogs, and several doubtful
                                  hits or near misses were observed.

FIRST ENDORSEMENT to
USS BAYA (SS318) -
Report of Fifth War
Patrol.

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

Subject: U.S.S. BAYA (SS318) - Report of Fifth War Patrol.

1. The fifth war patrol of the U.S.S. BAYA, under the
command of Lieutenant Commander B.C. Jarvis, was conducted in the
Java Sea, and was of 47 days duration, of which 31 days were spent
in the area. All patrolling was done on the surface, and area
coverage was excellent.

2. Five enemy contacts worthy of attack were made, of
which one could not be closed. The other four were aggressively
attacked as follows:

Torpedo Attack Number One was a submerged moonlight
attack against a radically zigging class 7-AM(C) on the early
morning of 27 June in the east end of MADOERA Strait. The target
was on an easterly course. Six Mark 14 torpedoes were fired on an
80 port track at 1300 yards for no hits. The torpedoes were set
to run at four feet in a calm sea. The spread of about four
hundred feet between wing torpedoes should have produced at least
two hits. The torpedoes were tracked out by sound and their smoke
wakes clearly seen crossing under the target. They no doubt ran
deeper than set. The subsequent depth charging was successfully
evaded with no damage. A similar ship was seen the next day in
the same vicinity, on a westerly course but could not be closed.
This was possibly the same ship returning to SOERABAJA via MADOERNA
Straits.

Gun Attack No. 1 was a coordinated moonlight gun-
shoot with CAPITAINE on a convoy of 5 small targets consisting of
2 SD, 1 SCS-1, and 1 PC, on a southwesterly course east of the
KANGEAN Islands. They were considered too small for torpedoes, so
an organized simultaneous gun-shoot was arranged with CAPITAINE,
both ships opening fire simultaneously, BAYA at 6000 yards closing.
At 4400 yards the return fire from all five ships became too heavy
and the engagement was broken off. It is recommended that damage
be assessed as follows:

Subject: U.S.S. BAYA (SS318) - Report of Fifth War Patrol.

                                        DAMAGED

1 SCS-1 (EC)                                                    100 tons
1 SD (EC)                                                       500 tons

BAYA then proceeded to her scouting position at dawn of 30 June,
leaving the convoy steering random courses, thoroughly disorgan-
ized, and under the scrutiny of CAPITAINE.

        Torpedo Attack No. 2 was a skillful night submerged
attack in the early morning of 16 July. This was directed at a
lone OTORI torpedo boat after BAYA observed BECUNA make her attack
and miss. The night was very dark but clear, and target was sighted
through the ST periscope at 3000 yards. Three Mark 18 torpedoes
were fired from the stern tubes on a 90 starboard track, small
gyros, torpedo run 1100 yards. Depth setting was zero feet in a
calm sea. One good hit in the stern was seen and heard, starting
fires. None of the torpedoes broached. As the target refused to
sink, one hour and a half later two Mark 14-3A torpedoes were
fired forward at 2700 yards. The first one, set at 4 feet, hit
amidships and disintegrated the OTORI leaving no trace for the
second one which was 28 seconds behind and set at 2 feet. Both
were observed to run true and neither broached. It is recommended
that the BAYA be credited with sinking one OTORI class torpedo
boat (EC) of 600 tons.

        Gun Attack No. 2 was another coordinated shoot, this
time with BLENNY on the morning of 20 July against a single PC
type vessel which had been tracked during the night on courses too
radical to permit a torpedo firing set-up. At dawn BLENNY and
BAYA opened fire simultaneously, BAYA at 8000 yards. After 40
minutes of shooting, during which the PC, maneuvering radically at
nearly 20 knots, returned the fire with small calibre and what
appeared to be 3 inch or better, the engagement was broken off,
with the PC retiring at full speed for SURABAYA. No hits were ob-
tained and no damage was suffered. Planes appeared at the scene
of the gun-shoot forty-five minutes after the engagement was broken
off.

SECOND ENDORSEMENT to:
USS BAYA Conf. Ltr. A16-3
Serial 06, dated 31 July,
1945. Report of Fifth
War Patrol.

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

Subject: U.S.S. BAYA (SS318) - Report of Fifth War
         Patrol - Comment on.

1. The Fifth War Patrol of the BAYA under the command
of Lieut. Comdr. B.C. JARVIS, U.S.N., was conducted in the JAVA
SEA. BAYA coordinated her patrol with BULLHEAD, PUFFER and ICEFISH.

2. The major part of this patrol was devoted to re-
connaissance duty in support of Allied landings at BALIKPAPAN,
BORNEO. At 0200 on 30 June, with a full moon high in the south-
east, a convoy of three small vessels and two escorts was brought
under coordinated gun attack by BAYA who attacked from the west,
and CAPITAINE who attacked from the north. The initial range of
6,000 yards was closed to 4,200 yards and then opened again as the
volume of fire from three inch deck guns and automatic weapons became
excessive. Two sea trucks were damaged and one subchaser was sunk
in this encounter. On 16 July BAYA hit an OTORI TB in the stern
with one torpedo, and caused it to stop and commence to burn aft.
One hour and twenty minutes later the target showed no signs of
sinking and was still on an even keel, so two more torpedoes were
fired and one hit disintegrated the OTORI. Lifeguard services were
performed off KOTA WARINGIN but no opportunity to effect rescue
presented itself.

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

4. The Commander Submarines SEVENTH FLEET, congratulates
the Commanding Officer, Officers and Crew of the BAYA for this
aggressive patrol during which the following damage was inflicted
upon the enemy:

SUNK
1 - OTORI Class TB (EU) 600 Tons (Att. No. 2)
1 - SubChaser SCS Class (EU) 100 Tons (Gun Att. No. 1)
                                Total Sunk 700 Tons
