Salmon

A soft-finned, gamy fish which inhabits the coasts of
America and Europe in northern latitudes and ascends
rivers for the purpose of spawning. Salmon are highly
valued for their rich, succulent meat.

Salmon (SS-19) was laid down on 16 April 1908 by
the Fore River Shipbuilding Co., Quincy, Mass., under
subcontract from Electric Boat Co., Groton, Conn.;
launched on 12 March 1910; sponsored by Miss R.
Fitzgerald; commissioned on 8 September 1910, Lt. D.
A. Weaver in command; and renamed D-3 (q.v.) on
17 November 1911.

Salmon (SS-182) was laid down on 15 April 1936 by
the Electric Boat Co., Groton, Conn.; launched on 12
June 1937; sponsored by Miss Hester Laning; and
commissioned on 15 March 1938, Lt. M. M. Stephens in
command.
     After shakedown training and trials along the At-
lantic coast from the West Indies to Nova Scotia,
Salmon joined Submarine Division 15, Squadron 6 of
the Submarine Force, U.S. Fleet, at Portsmouth, N.H.
As flagship of her division, she operated along the
Atlantic coast until she relinquished the flag to Snap-
per (SS-185) late in 1939 as the division was shifted
to the west coast at San Diego.
     Salmon operated along the west coast through 1940
and the greater portion of 1941. Late that year, she
was transferred with her division and the tender, Hol-
land, to the Asiatic station. On 18 November, Holland
with Salmon, Swordfish, Sturgeon, and Skipjack ar-
rived at Manila and formed SubDiv 21 of the Asiatic
fleet to bolster defenses in the Philippines as marked
tension was growing due to Japanese militarism.
     Salmon was conducting a patrol from Manila along
the west coast of Luzon at the time of the surprise air
raid by the Japanese against the Philippine bases and
Pearl Harbor. Having been on defensive deployment
since 27 November, in a wait-and-watch posture, she

Salmon (SS-182) running speed trials in 1938. As her appearance indicates, the process of evolution that would
result in the standardized "Fleet-type" submarines of World War II was well underway. Slightly larger and
heavier than the classes before them, the six submarines of the Salmon class mounted four torpedo tubes
in the bow and four more in the stern, two more stern tubes than the earlier post-World War I ships. From
1911 until 1931, American submarines bore letter-and-number names, as in the case of the "R-boats" and "S-
boats" described earlier in this volume. In 1931, all submarines after the S-classes were given the names of
the same class received names beginning with the same letter in addition to their (SS- ) hull
number. For visual identification, submarines also bore a class number, the first letter of the name with a
number indicating the boat's sequence within her class. Thus Salmon, the first of her class, wears the marking
S-1. Shortly before we entered World War II, the Navy discarded class numbers and introduced the con-
temporary practice of painting the hull number on bow and conning tower. This was suspended during the
war for security reasons, but resumed after V-J Day.

commenced war patrolling immediately upon receiving
word of the attack on Pearl Harbor. On 22 December, while on the
surface in the Lingayen Gulf, she encountered two
Japanese destroyers and pressed home an attack which
seemed to bewilder the reluctant enemy. She succeeded
in damaging both targets by delivering a "down the
throat" spread of torpedoes which caught them as they
veered course in an attempt to avoid further contact. She was then able
to avoid further contact by ducking into a rain squall.
In January 1942, she moved south to operate in the
Gulf of Davao and off the southern tip of Mindanao
and thence proceeded to Manipa Strait between Bura
and Cerain in the Moluccas Islands. In February, she
patrolled the Flores Sea from north of Timor to Lom-
bok Strait in the Sunda Islands, then put into Tji-
latjap on the south coast of Java on the 13th.
Losses suffered by ABDA forces in the battle at
Badoeng Strait exposed Tjilatjap as a possible trap. Holland moved
her base of operations to Exmouth Gulf, Australia, on
20 February, as Salmon set out on her second war
patrol.
Salmon spent the next month in the Java Sea on
Sepandjang and the area just west of
Bawean. She arrived at Fremantle, Australia, on 23
March to end her second patrol.
Beginning her third war patrol, Salmon departed
from Fremantle on 3 May and established a barrier
patrol along the south coast of Java to intercept Japa-
nese shipping. On 25 May, she torpedoed and sank the
11,441-ton repair ship, Asahi; and, on the 28th, the
4,382-ton passenger-cargo vessel, Ganges
Maru. On 24 June, Salmon proudly returned to Fre-
mantle and commenced preparations for her next as-
signment.
Salmon departed from Fremantle on 21 July for her
fourth war patrol in the South China-Sulu Seas area.
Sailing via Lombok and Makassar Straits, the Sibutu
Passage, and the Balabac Strait, she stationed herself
between North Borneo and Palawan, Philippine Is-
lands. During this patrol, Salmon was unable to gain a
favorable position for successful attack, but made nu-
merous sightings and reports of shipping movements to
sister subs in the vicinity. She returned to Fremantle
on 8 September.

Salmon's fifth war patrol began on 10 October, and
her area of operations was off Corregidor and Subic
Bay. On the night of 10 November, she challenged a
large sampan moving in the vicinity of Subic Bay,
during the hours of darkness. After ignoring the chal-
lenge, the vessel was ordered to stop and shots were
fired across its bow. Salmon then maneuvered for a
closer inspection and saw that the sampan was display-
ing rising sun emblems on its deckhouse and that its
crew was attempting to jettison objects over the side.
Salmon's crew took the sampan under fire and raked it
with .50 caliber machine guns. The vessel stopped and
was boarded by Salmon crewmen who found that most
of the Japanese sailors had gone over the side. They
removed papers, radio equipment, and other articles,
then set the sampan afire. As Salmon pulled away, the
sampan began to explode and sink. On 17
November, off the approach to Manila Bay, Salmon
sighted three vessels and maneuvered for attack. She
fired torpedoes at each of the ships and succeeded in
damaging two and sinking the 5,873-ton, converted
salvage vessel, Oregon Maru. Salmon ended her fifth
patrol on 7 December at Pearl Harbor. She then pro-
ceeded to Mare Island, California, the following day, and
arrived on the 13th. Salmon remained at Mare Island
until 30 March 1943, undergoing alterations including
the installation of new radar equipment and two
20mm. mounts to augment her firepower. She returned
to Pearl Harbor on 8 April.
Salmon departed from Pearl Harbor on 29 April for
her sixth war patrol via Midway. She was assigned a
special mission which took her to the coast of Honshu,
Japan, at Hachijo Shima, Kantori Saki, and O'Shima.
During this mission, she damaged two freighters on 3
June and returned to Midway on the 19th.
Her seventh patrol was conducted in the Ku-
riles to cut the Paramushiro-Aleutian supply route.
She departed from Midway on 17 July; sank a small
coastal patrol vessel on 9 August; and, on 10 August,
sank the 2,411-ton passenger-cargo vessel, Wakanoura
Maru off the northern coast of Hokkaido. She returned
to Pearl Harbor on the 25th.
Salmon's eighth war patrol saw her return to the
Kurils where she was credited with damaging two

266

— page 5 —
freighters. This patrol lasted from 27 September to 17
November when she returned to Pearl Harbor.
The ninth war patrol for Salmon was conducted
between 15 December and 25 February 1944. She suc-
ceeded in damaging one freighter on 22 January.
On 1 April, Salmon departed from Pearl Harbor en-
route to Johnston Island in company with Seadragon.
She was assigned a special photo reconnaissance mis-
sion for her tenth patrol which would assist in prepar-
ing plans for gaining control of the Caroline Islands.
She conducted a reconnaissance of Ulithi from 15 to 20
April; Yap from the 22nd to the 26th; and Woleai
Harbor on 21 May with much valuable information
that was utilized in last minute changes to the assault
plans.
Salmon's eleventh and last war patrol was conducted
in company with Trigger and Sterlet as a coordinated
attack group in the Ryukyu Islands. This patrol began
on 24 September. On 30 October, Salmon attacked a
large tanker that had been previously damaged by
Trigger. This tanker was protected by four antisub-
marine patrol vessels which were cruising back and
forth around the stricken ship. Salmon fired four torpe-
does and made two good hits, but was forced to dive
deep under a severe depth charge attack by the escorts.
She leveled off at 300 feet but was soon forced to
nearly 500 feet due to damage and additional pounding
of the depth charges. Unable to control leaking and
maintain depth level, she battle surfaced to fight for
survival on the surface.
The enemy seemed wary and held their distance
while sniffing out the situation, and gave Salmon's
crew a few precious minutes to correct a bad list and
to repair some damage. The vessels began to close, but
Salmon showing an aggressive stance, turned on the
attackers and passing within 50 yards down the side of
one, raked her with 20mm. gunfire and her deck gun.
Apparently killing the topside personnel of the patrol
escort which came to a stop, Salmon then exchanged
fire with a second which again seemed to hesitate at
some distance for reinforcement from the other two
which were coming to the scene. Salmon began sending
out plain language directions for all other subs in the
vicinity to attack, giving the position of the action.
This probably further discouraged the enemy who,
fearing other submarines in the area, began milling
around pinging on sound gear. Salmon took advantage
of a rain squall and slipped away.
Other than the damage caused by depth charges,
Salmon suffered only a few small caliber hits from the
enemy vessels. Escorted by Sterlet, Silversides, and
Trigger, she made it to Saipan. She was given one-
third credit for the 10,500-ton tanker, Jinei Maru,
which was eventually sunk by a Sterlet torpedo. On 3
November, she moored alongside tender, Fulton, in
Tanapag Harbor, Saipan.
On 10 November, Salmon stood out from Saipan, in
company with Holland, and sailed via Eniwetok and
Pearl Harbor to San Francisco. On 26 January 1945,
she departed from San Francisco with Redfish and
proceeded via the Panama Canal to Portsmouth, N.H.,
where she arrived on 17 February.
After repairs and overhaul at the Portsmouth Navy
Yard, Salmon was assigned as a training vessel for the
Atlantic Fleet. After the war's end, Salmon was slated
for disposal and was decommissioned on 24 September.
Struck from the Navy list on 11 October, she was
scrapped on 4 April 1946.
Salmon was awarded the Presidential Unit Citation
for extraordinary heroism against enemy surface ves-
sels during her eleventh war patrol in restricted, en-
emy-held waters of the Pacific.
Salmon earned nine battle stars for World War II
service in the Asiatic-Pacific area.

20 December 1941. [HANDWRITTEN: 9-2] [HANDWRITTEN: 12-64]

1540 - Underway standing out of Manila Bay.
1750 - Anchored off Mariveles.
1848 - After having thoroughly checked our position for the early
       morning exit received blinker message from guard ship, which
       was steaming around near the turning buoy, to "Get underway
       and come within hailing distance." Complied went back and
       anchored but it was then too dark to check our position or
       verify the position of the buoys thereafter.

21 December 1941.

0520 - Underway proceeding out of channel. At time of exit saw only
       two submarines anchored inside although there were supposed
       to be three.
0554 - Changed course to 220° True and stood out to 100 fathom curve.
0700 - Shortly after passing the 100 fathom curve picked up a sound
       which appeared to be propeller noises but bearings changed
       quickly and persisted even after our screws were stopped. It
       was finally decided that sounds were echos from the ship as
       it was then in the sharp horse shoe shaped pocket formed by
       the 100 fathom curve.
1940 - Surfaced (were about 25 miles north of Cabra Island) changed
       course to 270° True to proceed along 14°-22'-N. Maximum speed
       on 2, 3 and 4 main engines charging with no. 1.
2325 - Changed course to 000° True, weather fair, sky clear except
       large nimbus clouds along the horizon, sea smooth except for
       medium swells.

22 December 1941.

0115 - Secured battery charge and went ahead full speed.
0639 - Submerged and ran at 80 feet making periodic observations.
       Temperature of water 83° F. Moderately large swells running
       from N.W. Sky cloudy and overcast.
1535 - Changed course to 070° True.
1905 - Surfaced for fix - Sky cloudy and horizon poor.
1914 - Submerged.

22 December 1941.

1945 - Surfaced and started battery charge.
1958 - Changed course to 040°T. to enter assigned area.
2115 - Changed course to 110°T. to penetrate Gulf.
2315 - Changed course to 132°T.
2329 - Sighted what appeared to be a vessel abeam to starboard on
the horizon passing aft on opposite course.

23 December 1941.

0010 - Sighted 2 vessels bearing about 270° relative distance about
5,000 yards passing aft. They appeared to be destroyers.
0030 - These ships crossed astern and went as far as bearing of 160°
relative where they reversed and crossed over to port quarter.
They appeared to be closing in slowly. Steering various
courses to keep our stern pointed toward them. It was a long
run into the Gulf so if we were to get in there with any "Can"
we were going to have to make it on the surface.
Ships turned and crossed from port to starboard getting closer.
Made ready No. 7 and 8 tubes and when they again crossed
astern, fired by T.D.C. using a bearing of 180 when they were
astern. Set-up used: 90 st'bd track range 2500 yards speed
15 knots. Torpedoes went out on gyro angles about 205 and 210.
Both missed ahead, speed estimate was probably too high.
The ships appeared to stop, then crossed to the starboard
quarter where they commenced using blinker tubes to signal.
One tube was pointed directly toward us but our best signal-
man could not read or distinguish any letters. They appeared
to send very fast in word groups. They turned toward us and
started charging in at high speed, showing about 10 or 15
degrees angle on the port bow. We were ready on No. 5 and 6
tubes and fired on gyro angle of 175. The visibility was very
poor but it was estimated that the leading destroyer must
have been about 1,000 to 1,500 yards away when we saw and heard
a loud explosion on that bearing. The leading destroyer had
turned to starboard when we fired and the torpedo struck under
the bridge and was visible in the flash. The torpedo ran for
about one minute at high speed. Depth setting was 12 feet.
We had sounded the diving alarm when the first torpedo was
fired and just as everyone was below another loud explosion
was heard. Thereafter we heard one set of screws milling
around astern, first running at high speed then stopping.
Apparently both torpedoes struck the same destroyer and sunk
it.
0230 - After no sounds had been heard for over one hour surfaced in
order to penetrate. The seas were running fairly high and we
were on the bridge getting blown up when the sound watch re-
ported screws bearing 355°relative.

We had looked around good but it was very hazy in that
direction with land as a background and nothing had been
sighted. Out of the haze picked up a ship about 1,000
yards ahead showing a slight port angle and appeared to be
charging ahead. Dived immediately and believe this ship
passed down our port side close aboard. This ship stayed
right on us and would stop periodically to listen. We were
at 150 feet running dead quiet at 1/3 speed on one shaft
changing course accordingly and maneuvering to avoid. The
ship made seven separate depth charge attacks. Some appeared
to be fairly close but ship was never badly shaken. They
appeared to be about 300# charges, "Y" gun and were probably
going off at a depth or about 100 ft. We were then at 170
feet. Number one exhaust valve had been leaking and putting
quite a little water in the forward engine room and one of
the purposes of surfacing at 0230 had been to try and re-
seat this valve better but as we were driven down it was necessary
to use the pumps periodically in order maintain a trim and
keep the water below the floor plates. Made a large turn to
the right at slow speed and finally evaded the destroyer and
stood out on course 330°T.
About 0700 picked up a destroyer on our port bow echo-ranging.
The destroyer picked us up swinging around and came up on our
starboard side from aft close aboard. Crossed over ahead
and came down our port side close aboard. We were running
dead quiet at 1/3 speed on one shaft at 150 ft. Destroyer
would stop periodically to listen. Maneuvered on various
courses to escape. The destroyer screws grew fainter and
finally died out astern.
At 1415 a series of depth charges were dropped astern. This
continued for about two hours but none of them were very
close and sound picked up no screws. As each charge went
off there would be two pings on the hull, which sounded as though
two small nuts had been dropped, then after a period of
one or two seconds the depth charge would be heard.
1630 - Came to periscope depth and sighted a small sea plane passing
from west to east distant about four miles. No ships were in
sight.
1945 - Surfaced after observing that all was clear. The moon was up
and about 1/4 full. Ran down moon on course 260°T. Sky was
partially cloudy. Small swells were running with a few white
caps. Waves along the sides of the ship were very phosphorescent.
Commenced battery charge.

24 December 1941.
0046 - Changed course to 080°T 1/3 speed on one engine. Sky slightly
overcast - horizon good - slight ground swells with a few
white caps. Slight set to N.E. Temperature of water 88°F.

24 December 1941

0629 - Submerged to 60 feet and made periodic observations.
0832 - Changed course to 123°T. to close toward Gulf.
1210 - Changed course to 000°T.
1925 - Changed course to 225°T. to head toward moon when we sur-
       faced. Moon had risen and was about 1/2 full.
1945 - Surfaced and started battery charge. Sea had smoothed and
       was dead flat. Fairly good horizon.
2010 - Sighted a destroyer on the horizon abeam to port changed
       course to 230°T. Ship was not again sighted. Sound did not
       pick up this ship.
2030 - Sound thought they heard screws dead ahead but this was
       upon moon and clearly visible and there was nothing in sight.
       Sound was convinced this was a submarine but as the bearing
       would change rapidly across the bow from side to side it is
       more likely that this was a large fish. After chasing the
       sound for more than an hour went ahead full speed on One
       Two main engines changed course to the right with full rudder
       and ran out on course 070°T so as to remain within area.
       Sea was glassy and visibility became poorer as the horizon
       became more indefinite. Bow waves were phosphorescent.

25 December 1941

0600 - Sighted large fire on the beach bearing 070°T. which appeared
       to be near Santiago.
0640 - Submerged to 90 feet. Sea was very smooth, no wind and horizon
       was very hazy except in the east.
1300 - Heard series of depth charge explosions which seemed to be
       near the Gulf.
1935 - Changed course to 207°T. so as to surface in the path of the
       moon.
1942 - Surfaced and commenced battery charge. Making small changes
       of course to the right to keep headed toward the moon.

26 December 1941

0112 - Changed course to 330°T. Moon about 1/2 full. Few clouds in
       the sky, sea slightly choppy. Horizon fairly distinct.
       Temperature of water 83 degrees F. Have been unable to find
       any temperature gradients.
0630 - Submerged to 90 feet.
0700 - Heard series of depth charges some distance away. Came to
       periscope depth but could see nothing.
1240 - Sound reported screws bearing about 9 degrees relative. Came
       to periscope depth and sighted the tips of destroyer masts.
       It was making about 120 RPM. Bearing was drawing aft on the
       port side. Changed to normal approach course but masts
       disappeared over the horizon in the direction of Vigan.

1500 - Heard distant report in direction of Vigan - Sounded like a
torpedo.
1800 - Sound heard screws on starboard beam. Observed the masts of
two destroyers over the horizon. Sound reported there were
three ships. Changed course toward them but they moved for-
ward and over the horizon on course about 50°T. and were not
definitely identified.
1940 - Surfaced and started battery charge.
2045 - Sighted a large number of ships on both bows on about para-
llel and opposite course. We were headed right down the
middle of them. Shifted to battery and charged in with decks
and torpedoes awash. Made the tubes ready. Planned on firing
a right gyro shot as more ships seemed to be on the starboard
bow. They appeared to be strung out in a single line of bear-
ing. There must have been about ten of them with about four
ships strung out ahead which were probably destroyers. Had a
set-up on the T.D.C. to fire the bow tubes with gyro angles
of 60, 65, 70, and 75 degrees using a speed of about 12 knots.
It was very hazy and the outlines of the ships were indistinct
and it was fairly difficult to estimate any angle on the bow.
Gave sound the bearing of a target on the starboard bow which
was to be used for firing bearings. Submerged and was at
about 100 feet when about on the firing bearing when a severe
depth charge commenced. Two were very close aboard, knocked
people over, shattered light globes, popped off a few nut heads,
chipped off paint and started numerous pipe line leaks, especi-
ally in the air and hydraulic systems. Fired the four bow tubes
on about the proper bearings but due to depth charges close
aboard it was impossible to tell if any of them hit. One of
the charges gave us a big up angle and it was necessary to go
ahead emergency to catch it. Ran out at high speed during the
depth charging and as they seemed to be getting further away
slowed to 1/3 speed on one shaft and ran dead quiet. The screws
of the searching destroyers could be heard all around some
running at high speed and some stopped. The tactics seem to
be that they operate in pairs and take cross bearings and cut
you in. There is no doubt but what their sound equipment is
very good possibly the operators are not the best but they seem
to have very little difficulty in accurately picking up sub-
marines. They seem to echo-range on about 1,000, 3,000, 5000,
and 10,000 yard scales and they come in very clear. Maneuvered
on various courses and finally escaped on course 140°T. but
could still hear destroyers milling around and pinging trying
to pick us up. Missed the Baker schedules and wanted to report
the sortie but things were too hot and there were too many des-
troyers around. Finally ran over the western boundary of our
area surfaced and reported.

27 December 1941.

0255 - Surfaced and charged batteries. Good sea with white caps
       was running. Moon had set and horizon was very indefinite.
0625 - Submerged on course 330°True.
1937 - Surfaced and charged batteries. Sea rough with swells and
       white caps. Moon about 1/2 full overhead. Horizon distinct.

28 December 1941.

0425 - While on course 345°T sighted ship on surface bearing about
       270°T. distance about 4,000 yards making slow speed on about
       parallel and opposite course. Had a good star fix this night
       and knew we were at least four miles from the western bound-
       ary of our area. The outline looked as though it might be one
       of our submarines so turned away and submerged with challenge
       apparently dive. Heavy seas are running and periscope obser-
       vations are difficult as it is practically impossible to hold
       the boat at periscope depth.
1030 - Heard distant explosion which sounded like a torpedo.
1942 - Surfaced in a very rough sea. Waves were running high and
       wind was strong N.N.E. Many large white caps. Moon was over
       1/2 full and out overhead. Horizon was good with only occa-
       ional clouds.

29 December 1941.

0630 - Submerged on course 350°T. running at 120 feet listening and
       making occasional periscope observations.
1938 - Surfaced on course 330°T. Seas running high strong wind from
       north.

30 December 1941.

0635 - Submerged on course 000°T. running at 120 feet.
1940 - Surfaced on course 350°T. Sea is rough but seems to be get-
       ting smoother. Wind has died down considerably. Moon 3/4
       full, sky clear, horizon distinct with good visibility.

31 December 1941.

0100 - While on course 150°T. sound picked up echo-ranging bearing
       about 340 degrees relative. Searched this area carefully
       with glasses and sighted a single destroyer bearing 120 degrees
       true distance about 8,000 yards headed toward us.

      with air getting colder. Still getting strong set. Moon full
      and very bright with sky partially overcast.

3 January 1942

0650 - Submerged to 120 feet and changed course to 150° T. Because
      of better radio reception and the extreme difficulty of
      keeping within the area limits on runs up and down moon due
      to strong sets am maintaining patrol to North of area.
1930 - Surfaced and changed course to 020° T moon full near horizon
      bearing about 080° T. Seas rough, wind strong. There is a very
      definite heavy layer at about 100' but have been unable to
      take the temperature accurately as heavy seas broke the ther-
      mometer outside the eye port. Flooded number one main engine
      while attempting to start it on a battery charge. It fired
      and then stopped, before the throttleman could close his stop
      the engine took considerable water. After carefully working
      it over had it running again in about 2 hours - no apparent
      damage.

4 January 1942

0648 - Submerged and changed course to 090° psc as fix showed we
      had been set considerably to the westward.
1930 - Surfaced on course 220° psc seas are getting smoother and
      wind is dying down. Sky cloudy and horizon indistinct.
2007 - Moon arose. Magnetic compass shows an error of about 4-6
      degrees during and just after battery charge.

5 January 1942

2016 - One engine on charge three on propulsion proceeding to
       Basilian Straits in accordance with serial 70 making best
       speed. Communications very poor. Tried for about three hours
       on all frequencies to get off our acknowledgement. Finally
       raised NPO on 8470 and got it off.

       SE. Slightly overcast with fair horizon.
2035 - Sighted beams of searchlight bearing about 070° T over the
       horizon. Appeared to be from Corregidor.

11 January 1942

0633 - Submerged on course 155° psc.

0055 - Changed course to 170° psc so as to run in close to shore of
       Mindanao. Making full speed on all engines. As it was very
       dark with a poor horizon we timed ourselves so that the moon
       would be up when we changed to 090° psc to pass through

Basilian Straits. While passing thru the Straits there were
signals, apparently from blinker guns in the vicinity of
Zamboanga and on the other side of the channel.
0420 - Sighted small sailing vessel bearing about 120° T just North
of Coco Island on course about 280° T apparently heading for
Basilian Straits.
0440 - Acknowledged for serial 87 assigning us to the ex-Seawolf
area proceeding accordingly.
0630 - Submerged on course 117° psc. Exhaust valves are leaking to
such an extent that it is necessary to run the drain pump
about one-half the time.
1948 - Surfaced on course 117° psc. Sea calm, sky cloudy. The visib-
ility is very poor but occasional flashes of lightning
around the horizon helps considerably.

14 January 1942

0605 - Submerged on course 140° psc changed to course 120° psc
head for the center of assigned area.
1937 - Surfaced on course 270° psc. Changed to 290° psc to get clear
of Pickerel who is scheduled to pass thru our area this
night. Sea calm, sky overcast with light clouds, horizon good.

15 January 1942

0100 - Changed course to 110° psc to run back to the center of area.
0611 - Submerged. Morning fix showed that we had been set to the SW
of our DR about 30 miles. We had had no previous hint of such
a set. It has been previously noted that our gyro has been
acting up due to the fact that one rotor casing will not hold
a vacuum. Azimuths have shown it to be out as much as 13°
either way. Changed course to 000° psc to regain position.
1011 - Sound reported distant echo ranging. Went to battle stations.
Came to periscope depth and sighted three colums of smoke
between two ships. It appeared that there were about
the ships so that they would pass on both sides of us however
it was later noted that there was a gap between
the ships so that they would pass on both sides of us.
It appeared that there were about five ships in the column.
The ships were about 10,000 yards distant. We started the approach
course using high speed to close between observations.
Ships are still hull down but from the masts and smoke
there appears to be five of them. Sound picked up echo
ranging on our starboard beam. Came up and observed a
destroyer cutting across our bow. Apparently patrolling
up and down the column.
1115 - Made ready the bow tubes in hopes of at least getting
a shot at the destroyer which crossed ahead distant about
5,000 yards. Although sound reported that the destroyer

was pinging right on us he apparently did not pick
Did not fire on the destroyer as still had hopes of getting
in on the convoy which then appeared to be on course 220° T
making about 10-12 knots. Destroyer reversed course and
was now running back down the column but at a greater range.
Ships were now showing an angle of about 120° port and seemed
to be drawing away. It was now evident that we were going to
miss out on an attack if they maintained the present course
but held on in the hope they would change course back to the
left but they never did. Although no planes were actually
sighted something that looked like a wooden box was observed
near us during an early observation.
1350 - Surfaced to send out contact report, as usual we could not
no station on the contact frequency. Sent it out blind twice.
Repeated attempts to raise someone without success. It was
too risky to remain on the surface any longer sent out
report blind two more times and then submerged. While on the
surface sighted a sailing vessel on the horizon bearing about
060° T with the periscope but it was not visible from the
bridge.
1406 - Submerged on course 330° psc then changed to 020° psc. After
running generally North from the time we submerged at 0525 this
morning and for over two hours during the attack we found
ourselves, due to the set, in about the same spot.
1445 - Heard an explosion which sounded like a bomb some distance
away. Went to 150'.
1932 - Surfaced on course 020° pgc. Sea light swell from NE. Sky
generally clear with light clouds in the West. Gentle wind
from North, horizon good.

0110 - Submerged and changed course to 320°T. Patrol prevented us
       from getting battery fully charged.
0605 - Sound reported screws bearing about 090 degrees true but could
       not see anything on that bearing. Periscope observations are
       difficult due to high waves and it would be difficult to shoot
       a torpedo set for shallow depth.

0942 - Steering by magnetic compass as south gyro rotor is out and
       master gyro is erratic. The pit log is not working properly
       which along with the strong currents in this area makes steering
       difficult and uncertain.

1932 - Surfaced on course 260° psc. Seas rough, moon about 3/4 full,
       wind strong about NNE, sky clear and horizon good.
2110 - Sighted destroyer bearing about 070°T. Distance about 8,000
       yards heading directly toward us. Sound did not pick him up
       nor did we pick him up with Radar. Destroyer was making good
       speed and undoubtedly had picked us up with Radar. Submerged
       and made ready the forward tubes hoping to make a night attack
       submerged but considered it not practical to fire torpedoes
       for a 10 foot depth designed to hit due to the state of the
       sea. Sound did not pick him up nor was he sighted thereafter
       by periscope. Submerged to 120 feet
       and changed course to 350° psc.

0110 - After listening and looking around changed course to 290 psc.
       to run down path of setting moon and surfaced. Seas were very
       rough.
0158 - Sighted DD bearing 160 degrees relative, smoking and apparently
       making high speed directly toward us. Submerged.
0210 - Changed course to 330 psc. and went to 120 feet and ran out
       dead slow speed as battery was not charged up. Am shifting
       north of area in order to get in a battery charge tomorrow
       and receive Baker schedules which we have been missing due
       being forced down by the patrol vessels in this area.
0445 - Heard distant depth charge explosion.
1931 - Surfaced on course 350° psc and commenced battery charge.
       Moon full bearing about 080°T. Seas very rough, cannot use
       main induction. Charging with one engine taking suction through
       Conning Tower hatch. Wind very strong from north. There is
       a set of 210 degrees True the drift is over 3 knots and it is
       very difficult to maintain station by D.R. This area is in a
       radio skip distance and makes reception difficult. Everything
       fades out about midnight.

1929 - Surfaced on course 180° pgc. Making night runs on East-West
     line across Straits. Sky generally clear with occasional heavy
     cloud with rain squalls. Heavy rip tides cause flashes of
     phosphorous all over the water which are very confusing as
     they are so bright that they look like the flashing of blinker
     guns.

     and depth control difficult.

     course to 180° to pass through the Straits and patrol East
     of Ambon in accordance with serial 49.

     stern plane man held his power handle over on rise but the
     shaft did not turn and the indicator did not move. He imme-
     diately shifted to hand power and brought the indicator to zero.
     The boat started to take an up angle and dive was put on the
     stern planes and speed increased. The up angle kept getting
     worse until it was about 20 degrees. Blew the after group

safety tank and surfaced. An examination revealed that the
stern plane shafting had sheared just forward of the chain
drive in the after engine room. Power was working the planes
all the time but the angle was not being indicated because
the shafting was sheared and hand power was not controlling
the planes. It was found that the stern planes were actually
on about 18 degrees rise while the indicator in the control
room showed that they had been moved to hard dive by hand
power.
0940 - Submerged and maintained proper angle by phone communication
with the after torpedo room with stern plane control on
power, the talker transmitting the angle settings of the
stern planes. This might have been a very serious casualty
and under certain conditions might have resulted in the
loss of the boat and is considered worthy of wide disseminat-
ion.

1532 - Returned to patrol station.
1532 - While on course 140 pgc sighted smoke from a single ship bearing
      064 T. very low on the horizon. Went to 120 feet and ran at
      hight speed for one hour and took another observation. Bear-
      ing of smoke had changed about 30 degrees but there was no in-
      dication there was more than one ship hull down. Went a
      standard speed for one hour and took another observation.
      Smoke of about six transports about dead ahead hulls down. No
      destroyer patrol was sighted and sound was unable to pick up
      any of the targets. Estimated the course must be about 155 T.
      speed 15 knots. Although no planes had been sighted it appeared
      that the convoy must have known where we were because they skirted
      the far side of the channel and from the smoke they were putting
      out must have been making maximum speed.
1914 - Surfaced on course 130 pgc and changed to 155 pgc. Sent out
      contact report and went ahead on all engines, to trail. Lost
      sight of ships but continued trailing in the direction of Ambon,
      visibility decreasing all the time. As it appeared ships had entered
      Piru Bay, turned in there to investigate conditions and while
      just passing the entrance when a destroyer was sighted bow
      bow heading toward us at high speed. We had the disadvantage of
      the light as their background was hazy against the land and our
      outline was clear and sharp in the entrance.
2323 - Submerged on course 070 pgc and went to battle stations. Not
      sure we had been sighted as they were quite a distance and in-
      tended to try and run past them submerged but they picked us up
      and commenced depth charge attack, no damage. The current around
      the entrance to the bay are strong and erratic and the small
      entrance limited our evasion tactics. Changed course to 290
      pgc and headed out at slow speed. Destroyers continued around
      around close to us and echo ranging which was not very satisfact-
      ory due to the reverberations from the steep banks around the
      entrance. Gradually sound of screws and echo ranging drew aft.

31 January, 1942

0108 - Came to periscope depth to verify position and to see if we
      were clear of the entrance. Sound picked up the screws of an-
      other destroyer bearing about 050 T. which would have put him
      outside of the entrance and from his movements he seemed to be
      searching the area around Tg Sial. He was not sighted through
      the periscope and apparently we were not picked up by him.
0331 - Surfaced on course 290 pgc and sent out report. Sky clear and
      horizon good except for haze along shore line. Moon is up. Pat-
      rolling off Piru Bay along the line to Manipa Straits.

2245 - Sighted small sailing vessel ahead passing from port to star-
       board across strait. Changed course to 180 pgc to avoid de-
       tection.

28 January, 1942.

0250 - Sound reported screws bearing 000 making 160 rpm's. Picked up
       a small dark object on the horizon, distant about 8000 yards
       which appeared to be a submarine on northerly course. As it was
       probable that the SHARK would pass through this area enroute
       to new station, changed course to 180 pgc to avoid. No chal-
       lenges were made.
1918 - Submerged on course 070 pgc.
2038 - Surfaced on course 235 pgc.

2035 - Sighted ship dead ahead, distant about 10,000 yards. Appeared
       to be heading directly toward us. Put our stern toward him,
       went to battle stations and made ready the stern tubes. Stayed
       in order to enable sound to get a turn count, but sound was
       unable to pick up anything. Finally identified ship as a fairly
       large sailing vessel which was standing toward the straits
       along the east coast of Buru.
2131 - Secured from battle stations and drained after tubes.

       sighted three small sailing vessels along the coast of Mani-
       pa and Serang.
1928 - Surfaced on course 235 pgc. Sky overcast with many nimbus
       and occasional showers. Wind and sea from N.W. Fair horizon
       which improved as moon came out.

30 January, 1942.

0510 - While on course 180 pgc at north entrance Manipa Straits saw
       several lights and what appeared to be a small searchlight
       bearing 260 T., distant about five miles. Changed course to
       270 pgc and went to battle stations. It became light and noth-
       ing was visible around the horizon. Our course was heading
       us toward Buru north coast.
0624 - Submerged on course 270 pgc without picking up any ships or
       sighting the lights again. Sound was never able to pick up any-
       thing around that bearing. Saw a large fire just east of Kayeli
       Bay. Ran down into the entrance and looked around but could see
       no ships or planes there. There appeared to be some smoke as
       though from ships at Wa Eplau Bay. Ran up that way and had a
       good look. Apparent smoke turned out to be tall odd shaped
       trees.

0614 - Submerged to 35 feet when the engine room reported the star-
       board clutch cooler was leaking badly. Surfaced and cut out the
       cooler and found that an adapter for a thermometer had corroded
       away, permitting the thermometer to be blown out.
0618 - Submerged on course 110 pgc.
1413 - Sound reported echo ranging bearing about 085 T., changed course
       to 075 pgc and sighted the masts and stack of a destroyer patrol-
       ling outside the entrance to Piru Bay. No other ships were sight-
       ed but the presence of the patrol indicated there might be a
       sortie this night.
1538 - Changed course to 300 pgc and ran out in order to get the bat-
       tery charged up for a night sortie. Echo ranging continued but
       gradually died out.
1935 - Surfaced on course 270 pgc, changed course to 290 pgc to main-
       tain position on the Piru Bay - Manipa Strait line.
2035 - Changed course to 190 pgc enroute for Surabaya in accordance
       with serial 22. Sea choppy, light breeze from N.W. Moon is up
       and horizon is clear. Occasional squalls. Sent out report of
       patrol off Piru Bay.

3. February, 1942.

0624 - Submerged on course 221 pgc. Sky partially cloudy, sea moderate
       with swells from N.W. Visibility good.
1932 - Surfaced on course 221 pgc. Sky partially overcast. Sea moderate
       with swells from N.W. Visibility good.
2313 - Developed leak in elbow of lub oil supply line to No. 3 engine
       which necessitated stopping the engine, removing the elbow and
       soldering up the crack.

4 February, 1942.

0500 - No. 3 engine back in commission.
0624 - Submerged on course 235 pgc.
1934 - Surfaced on course 235 pgc. Sky partially overcast. Sea moderate
       with light winds from west. Horizon clear.
1938 - Changed course to 250 pgc.

5 February 1942

0030 - Developed an oil leak in the casing of lub oil cooler to
     number one engine necessitating stopping the engine. Cooler
     must be removed to repair leaks however a baffle was rigged
     to catch and save the oil in order to permit the use of the
     engine. This appears to be a latent defect in design as there
     is no way of cross connecting the coolers so as to be able to
     run the engine.
0630 - Burned out a switch on supply panel to the lighting motor
     generator.
0638 - Shifted to the battery and got a report on all hull openings
     as indicator lights were out in the control room.
0640 - Submerged on course 250° pgc. There is a strong set to East
     and we are making good only about fifteen miles during day
     submerged runs.
0735 - Switch replaced and panel for lighting motor generator back
     in commission.
1655 - Cut showed that we were encountering a strong SE set.
1953 - Surfaced on course 250° pgc. Sea calm with swells from NW.
     Sky overcast with occasional rain squalls, visibility fair.
     Overheating of main motor pinion bearings has limited our
     speed to 240 RPM, it will be necessary to pull these bearings
     and scrape them in at the first opportunity as it appears
     that they might be slightly wiped.

6 February 1942

0601 - Changed course to 000° pgc to hunt along the line assigned
     by serial 34.
0624 - Submerged on course 000° pgc.
1130 - While inspecting main engines discovered that the babbitt
     band on number eight piston of number one engine was broken
     out and that the piston would require replacement.
1945 - Surfaced on course 000° pgc. Fix, verified by cuts, showed
     that we had been set along 125° T for a distance of twenty-
     nine miles in the last twenty-three hours. Sky overcast,
     moderate sea, light wind with periodic lightning and showers,
     visibility fair.

7 February 1942

     Main engine exhaust valves have been leaking quite badly
     during dives, men went down on deck and ground them in.
0600 - Completed replacing piston on number one engine and ran it
     under no load for ten minutes.
0635 - Submerged on course 180° pgc.
1950 - Surfaced on course 325° pgc. Sky partially overcast, slight
     wind and sea from West, visibility fair.
2005 - Fix showed that we had been set along 110° T for a distance
     of twenty-two miles in the last fourteen hours.

0640 - Submerged on course 000° pgc. Completely out of coffee, sugar,
       butter, canned cream and other important food.
1955 - Surfaced on course 180° pgc. Sky overcast with occasional rain
       squalls. Light wind and sea from West. Visibility 5,000 yards,
       horizon poor. Strong set to SE prevails.

9 February 1942

0230 - Speeded up and changed course to 255° pgc enroute to patrol
       station off Bima Bay assigned by CSAF No. 53.
0640 - Submerged on course 270° pgc patrolling off Bima.
2013 - Surfaced on course 225° pgc. Sky partially overcast, wind and
       sea from West. Horizon fair. Experienced considerable set to the
       North all morning but changed and set to the South about noon.

10 February 1942

0000 - Changed course to 280° pgc proceeding to Tjilatlap in accord-
       ance with CSAF serial 58.

       10° at 120 feet.
1810 - Follow up system on gyro compass went out.
2030 - Surfaced on course 295° pgc. The air conditioning system was
       out of order during this day submergence. At time of surfacing
       several men had headaches and there was noticeable fatigue
       amongst the crew. It is obvious that the resistance of all the
       hands has been reduced considerably during the patrol. Sky
       overcast, sea and wind from West. Visibility and horizon good.

12 February 1942

0725 - Submerged on course 275° pgc.
1550 - Gyro compass again in use but running to rotors with no
       vacuum.
2031 - Surfaced on course 270° pgc.
2042 - Changed course to 294° pgc. Sky partially overcast. Sea and

1000 Completed installation and assembly of No. 1 lub oil cooler
and subjected it to an oil pressure of 6 lbs. Casing
leaking over an area about 18 inches in length with the oil
cold. Leaks are so bad it will be impossible to operate
No. 1 engine without an excessive loss of lub oil.

1937 Surfaced on course 110° T. Sky clear. Moon up about 1/3 full,
sea calm and horizon good.

February 23, 1942.

0550 Submerged on course 090° T., making periodic periscope
observations.

1659 Changed course to 020° T., to enter Alas Strait.

1910 Surfaced on course 020° T. Sky generally clear, light sea
and breeze from north. Moon up 1/2 full, visibility good.
While passing through the strait sighted several
lights along the western shore of Soembawa.

February 24, 1942.

0542 Submerged on course 079° T. Changed course to 270° T, patrolling
in assigned area north of Soembawa in accordance with serial 8.
Encountered set along 110° T, drift 1 to 1 1/2 knots.

1916 Surfaced on course 270° T. Sky clear, sea smooth, moon up
about 1/2 full. Horizon clear and visibility good.

1920 Changed course to 000° T running up toward pass, anticipating
orders to move this night.

1934 Sighted a large ship on the horizon bearing about 10° T,
distant about 4 miles, showing about a 20° starboard
angle.
Went to battle stations and swung right with full rudder to
head directly toward the target. Sighted two smaller ships
on the starboard side of the target and possibly another on
the port side which appeared to be destroyers. Large ship
began to make considerable smoke from what appeared to be
a large single stack. Just as turn was about completed this
ship turned a large searchlight directly on us. Immediately
submerged and sound reported 2 DD's making high speed (210
rpm's) were charging directly toward us.

1944 Submerged to 170 feet and shortly thereafter depth charge
attacks commenced. Over the period of the next hour at least

fourteen depth charges were dropped, some of them being
double charges. These depth charges were unlike any we had
previously experienced. The original "pings" were much
louder and sharper and sounded as though a pair of heavy
leads were being dropped on the hull. These were followed
by a large surge of water which was clearly audible and
caused the boat to vibrate considerably and made depth control
difficult. Sound reported that these charges were unlike
anything they had previously heard and that they had the
effect of blanking out the sound gear for a much longer period
of time. No loud explosions were heard with these charges
but instead there was a sort of sizzling sound which always
accompanied the surges of water as though they were a type of air
propelled charge. The destroyers employed the usual tactics of
ranging, stopping and listening and then charging in at high
speed to deliver the attack. Sound reported other faint
screws on various bearings to the south. Evidently the
ships sighted were the van guard of a convoy but this was not actually
sighted. When attacks ceased and echo ranging became more
distant came to periscope depth and took a look around
nothing was in sight within the limited range or visibility
surfaced on course 100° T and observed gunfire apparently from
several ships and from the shore in the vicinity of Kawanda
on the Island of Soembawa. As battery was down and we had
but one charging engine in commission ran out on course 050° T
and attempted to get off the contact report. P.K.K. could
hear us on one frequency, strength one, but could not hear us
on another. Finally raised N.P.O., transmitted the message
and got a receipt. Changed course to 2250 T., and ran at
best speed toward Kawienda. Gun fire ceased gradually
stopped. Could not make out any ships and it is impossible
to say whether they had moved through Alas Straits or had
gone west.

February 25, 1942.

0550 Submerged on course 270° T making periodic observations from
120 feet. Nothing sighted.

1950 Surfaced on course 270° T. Sky clear, moon up about 1/2 full,
light breeze from east. Horizon and visibility good.

2250 Sighted large single ship bearing 125° T, distant about 5
miles, in view of last nights experience of being illuminated,
submerged immediately. Ship was heading toward us about
about a 10° starboard angle. Felt certain we were not actually
sighted but had been picked up by radar as shortly after we
had submerged target dropped two depth charges of the regular
detonating type at considerable range. Stayed at periscope

depth, tracked the target by sound in addition to being able
to make out a shape and bearing by periscope. Target seemed
to be zig-zagging slightly as he approached. As we found
it hopeless to find a course which would improve the track.
Target continued to drop depth charges as he approached and
finally when the range had decreased to less than 2000 yards,
fired two torpedoes set for 12 feet on gyro angles 180° and
190° for a 16° and 20° starboard track. Both torpedoes were
heard to run hot but missed. After we had determined the
torpedoes had missed, fired two more stern shots on gyro
or 205 and 210 for a 25° and 30° starboard track. Target
right and charged directly toward us, torpedoes probably
ahead. Both were set for 12 feet and were heard to run
hot. Two depth charges were dropped as it appeared target was
close aboard, shook us up considerably and knocked out a few
lights but no serious damage was done. Turned left and speeded
up as these charges were dropped as it appeared target was
passing up our starboard side at high speed (230 rpm's). Sound
of his screws gradually grew fainter and disappeared. Target
could not be identified.

February 28, 1942.
0100 Surfaced on course 090° T and sent out contact report.
0604 Submerged on course 260° T.
1910 Surfaced on course 250° T. Sky clear, moon up 3/4 full, light
     breeze from east. Horizon and visibility good.

February 27, 1942.
0040 Sighted three large war vessels which appeared to be cruisers
     bearing about 325° T, distant about 4 miles, showing about
     70° port angle on course about 210° T, speed about 15 knots.
     There were about 3 smaller ships in the van which appeared
     to be destroyers. It was bright moonlight but could not definitely
     determine the class or cruiser but they were definitely cruisers.
     Submerged and changed course to 270° T and ran at high speed
     for about one hour. Ships were not picked up by sound nor
     were they seen thereafter in the periscope although there was
     a good horizon all around.
0135 Surfaced on course 270° T, nothing in sight. Sent out contact
     report.
0324 Sighted three ships astern bearing about 310° showing various
     angles on the bow at an estimated range of 8500 yards. Moon
     had set and visibility was very poor. Although these ships

were not definitely identified, they were probably destroyers.
Sound could not pick these ships up even after we had stopped
our screws. Went to battle stations and made ready two
tubes.

0327 Submerged on course 310° T and changed course to 225° T.
Background water noises were very bad and sound was unable
to pick up any targets and nothing could be seen through
the periscope so remained submerged.

1920 Surfaced on course 110° T. Moon up full, sky clear, sea calm
with light breeze from S.W. Horizon and visibility good.

February 28, 1942.

0536 Sighted a submarine on the surface bearing about 065° T.
distant about 4 miles on course about 220° T. Submarine
appeared to be one of ours, however submerged without
exchanging signals. After submerging made a periscope
observation but nothing was in sight.

0540 Changed course to 000° T.

0736 Sound reported screws bearing 110° T but nothing could be seen
on that bearing through the periscope. The sound gradually
drew aft and passed astern.

1920 Surfaced on course 015° T. Sky clear, moon up full, sea calm
with light breeze from East. Horizon and visibility good.

March 1, 1942.

0622 Submerged on course 270° T.

1925 Surfaced on course 270° T. Moon up, sky partially cloudy, sea
calm, light breeze from S.W. Horizon and visibility good.

March 2, 1942.

0045 At Latitude 6°-10'S Longitude 113°-15' E sighted a single
large ship bearing 280° T showing about a 90° port angle at
a range of about 9000 yards. Submerged to periscope depth
and took an observation but target could not be seen. Sound
picked up screws on the port bow which seemed to be coming
closer. Finally picked up the target in the periscope and
found that the target had made a radical change of course
to the left. Commenced an attack on the ship which was zig-
zagging and was definitely identified as a KUMA class cruiser.

Fired a total of four torpedoes set for a depth of ten feet.
All torpedoes ran hot but all missed. Target made a wide
sweep to the left and disappeared over the horizon making high
speed.

0152 Changed course to 270° T and surfaced.

0328 Heard sound of a plane but was unable to sight it.

0558 At Latitude 6°-10' S Longitude 112°-27'E sighted three ships
on the starboard bow bearing about 350° T, distant about four
miles showing about a 70° starboard angle. Submerged and
swung toward them with full rudder. Received the report that
the after engine exhaust valves were leaking badly. Observed
the destroyer heading toward us showing about a 10° starboard
angle. Exhaust valves were leaking so badly it was necessary to
use both the trim pump and drain pump to keep it down. The
diving officer could not keep any sort of a trim. The
destroyer dropped two depth charges and we put our stern toward
him as we could not run silent with the pumps working. He
passed astern and dropped two depth charges which shook us up
considerably although they seemed to be some distance astern.
It may have been because we were so close to the bottom. We
not want to bottom because we wanted to use the sound gear
as we could still hear the destroyer milling around astern
fathometer soundings. We managed to sneak away with our pumps
running full blast but it was not a pleasant situation. No
other ships were heard.

1935 Surfaced on course 340° T. Moon up full, sky partially cloudy,
sea slightly choppy, light wind from east. Horizon and
visibility good. Men went on deck and ground in leaky exhaust
valves.

2235 At Latitude 5°-30' S Longitude 112°-25' E sighted four ships
apparently two destroyers and two transports bearing 060° T
on a course about north, distant about four miles. Submerged
and changed course to 040° T to head in for an attack. Could
not pick up the targets by periscope. Sound picked up screws
bearing 062° relative. Finally picked up a screening destroyer
in the periscope showing about a 10° port angle. Destroyer
started making high speed. Submerged to 150 feet and manned
stations for depth charge attack. Changed course to 190° and
destroyer passed astern but did not drop any charges. Came
to periscope depth but could not pick up any targets. Sound
reported they could hear something bearing about 310° T. Changed
course to 310° T and could finally make out two ships
about 140° port angle at a range of about 6000 yards. No attack.

2358 While on course 180° T sound reported screws on our starboard
quarter bearing about 315° T. Sighted two destroyers in the
periscope on course about south passing down our starboard
side at a range of about 6000 yards. Destroyers passed from
previously sighted, returning for more ships.

March 3, 1942.

0043 Changed course to 090° T surfaced to charge batteries and
air banks which are still very low from all the activity
this day.

0620 Submerged on course 270° T making periodic observations.
There is a distinct light surface layer with considerable
surface current which makes steering difficult.

1924 Surfaced on course 090° T. Moon just up. Sky cloudy, sea
choppy. Horizon and visibility good.

March 4, 1942.

0612 Submerged on course 270° T, periodic observations. There is
a decided light layer at about 90 feet. Made an examination
of rings and supercharge system of No. 2 main engine and
found three broken rings and some bits of metal in the
housing. As number one main engine cannot be operated
without an excessive loss of lub oil this engine must be
used for charges each night.

1850 Casualty to No. 1 I.C. motor generator. Locking nut backed
off allowing armature to move and bind on the slip rings.

1930 Surfaced on course 080° T. Sky cloudy, sea choppy. Horizon
and visibility fair. Moon not yet up.

2252 At about Latitude 5-30 S 112-30 E sighted single ship bearing
about 030° T distant about four miles showing about a zero
angle on bow. Submerged on course 080° T. Sound picked up
high speed screws bearing about 020° T and a ship which
appeared to be a destroyer was sighted in the periscope
directly toward us and closing rapidly. Submerged to 170
feet and manned stations for depth charge attack. Target
apparently stopped as sound reported that they had lost the
screws.

2347 Came to periscope depth and took a look around and could not
see any targets and sound could hear nothing so it is difficult
to ascertain just what became of the target although upon
surfacing there were streaks around in the area as though
from the wake of a ship.

0152 After looking and listening carefully, surfaced on course
     080° T.

0228 At about Latitude 5-35S 112-35E sighted a ship bearing about
     020° T distant about five miles, showing about a 10° port
     angle. Submerged to periscope depth.

0246 Sighted a large ship through the periscope bearing about
     013° T and coached sound on. Sound picked up the screws
     of a screening destroyer ahead of this bearing. Made ready
     the forward tubes and commenced the attack using the T.D.C.
     Fired two torpedoes using gyro angles of zero and 358 on
     117° and 119° port track. Both torpedoes were set for 10
     feet and sound heard both run hot and toward the bearing of
     the heavier screws. One minute and twenty seconds after
     firing there was a terrific explosion. Submerged to 170
     feet and changed course to right to 355° T. Sound reported
     high speed screws were getting closer but bearings were
     dropping aft. The escort destroyer was evidently running
     back down our torpedo track. When about astern he start
     dropping depth charges very deliberately and dropped a to
     of seven charges which seemed very close and shook us up
     considerably. These charges stopped no. 4 battery blower,
     put out some lights, knocked off a great deal of paint and
     took some water through the conning tower door. By gauge
     we lost about 1000 gallons of fuel from expansion tank.
     Searching destroyer crossed astern and circled back and
     dropped two more charges. Although these charges must ha
     been 1500 yards astern we were again shaken badly. Either
     these depth charges are stronger than those previously
     experienced or the shallower water (210 feet) gives them
     greater effect. The target was identified as a KATORI
     class cruiser.

1929 Surfaced on course 180° T. Sky clear, sea calm, light wind
     from east. Horizon and visibility good.

March 6, 1942.

0103 While on course 270° T sighted two ships which appeared to
     be destroyers, bearing about 250° T, distant about five miles,
     showing about a 70° starboard angle and appeared to be
     searching the area or last nights attack. Submerged to
     periscope depth and changed course to 340° T. Searched the
     area with periscope and sound but targets were not seen nor
     heard.

T, distant about three miles, showing a zero angle on the bow.
Submerged to 140 feet and changed course to the right and
prepared for depth charge attack. After submerging sound
could not pick up the target. As this has happened before
it may indicate that the destroyers turn away as soon as we
submerge. The noticeable light layer at about 90 feet seems
to have considerable effect on sound conditions.

Proceeding south of barrier in accordance with CSAF 64.
Selected route north of Kangean and through Sape Straits
so as to interfere as little as possible with other subs
and at the same time withhold from the enemy information
as to the number of submarines passing through the barrier.

0257 While passing north of PORPOISE area sighted small ship
bearing about 180° T, distant about 8000 yards. This was
presumed to be the PORPOISE. As the bearing drew steadily
aft no challenges were made.

0441 Sighted considerable debris in the water about 1000 - 2000
yards abeam to port. Appeared as though a ship might have
burned. It was apparently just wreckage as there were no

Vessels sighted and attacks.

February 20, 1942. Sighted merchant vessel of about 7000 tons on
course about 280° T, speed about 6 knots, bearing S.W. of KA-
RUNG BATA, distant about 5 miles, apparently headed for TJILATJAP. As
probably the same vessel reported by the SEAL's 19-1530 no additional
contact report was sent.

February 24, 1942. At about Latitude 7°-40'S Longitude 116°-
18'E sighted a large single stack ship bearing about 100° T, distant about
4 miles, showing about a 20° starboard angle. On course west, speed about 16
with 3 destroyer escorts. Swung toward target with full rudder and
cruiser turned a large searchlight directly on us. Submerged and
underwent depth charging for about one hour. Did not get in an
attack. See narrative for comments on the type of depth charges
used and general remarks for comments on tactics employed.

February 25, 1942. At about Latitude 7°-50'S Longitude 116°-15'E
sighted large ship bearing 125° T, distant about 5 miles. Ship
appeared to be a single stack cruiser but could not identify the
class. Submerged to periscope depth and ship dropped 2 distant
depth charges. Remained at periscope depth and tracked target
by sound and periscope bearings. Made several attempts to turn
away so as to improve the track but on each occasion the target
appeared to zig toward so as to decrease it. Finally when range
had decreased to less than 2000 yards target was showing a small
starboard angle. Fired two torpedoes from aft on a T.D.C. set up
gyro angles of 186° and 190° on a 16° and 20° starboard track of
12 feet. Both torpedoes were heard to run hot but missed. Target
continued to drop depth charges. Fired 2 more torpedoes from
on a new T.D.C. set up after a new periscope bearing had been
in. Torpedoes went out on gyro angles of 205° and 210° for a
30° starboard track. Torpedoes were set for 12 feet and both
heard to run hot. Target was making 230 r.p.m.'s at an estimated
speed of 20 knots. Target changed course to the right dropped
charges close aboard to starboard and disappeared still making high
speed. [HANDWRITTEN: (4)]

February 27, 1942. At about Latitude 7°-30'S Longitude 116°-10'E
sighted 3 large war ships in column with about 3 destroyers up
ahead bearing about 325° T, distant about 4 miles, showing about a
70° port angle. Moon was out very bright but was unable to
identify the class, however they resembled the lines of the NA-
GAKA class but the stacks could not be distinguished. Submerged and
changed course to 270° T and ran at high speed for about one hour.
Sound could not pick them up nor were they thereafter observed in
the periscope although the horizon was distinct all around. No attack
completed.

About 3 hours later in about the same position sighted 3 ships on
the port quarter bearing 310° T showing various angles on the bow at
an estimated range of 2500 yards. Moon had set and visibility was
poor. Ships may have cut us in from the last contact report or may
have picked us up by radar, in any event they appeared to be searching
the area. The background noises were very bad and sound had not
picked them up. Submerged to periscope depth but they could not be
seen nor heard thereafter. These ships were probably destroyers but
the visibility was so poor they could not be identified definitely.
Remained submerged so no contact report was sent out.

February 28, 1942. Sighted a submarine about 15 miles southeast of
Sekama Island of the Kangean group bearing 065° T distant about 4
miles on course about 220° T. Submarine appeared to be one of our
own. Submerged without exchanging recognition signals. Made an
immediate periscope observation but other submarine was not in sight.

March 2, 1942. At 0045 at Latitude 6-10S Longitude 113-15E
sighted a single large ship bearing about 280° T range about 8000 yards
showing about a 90° port angle crossing our bow from starboard to
port. Submerged to periscope depth but could not make out the target.
Sound picked up screws on the port bow which seemed to be coming
closer. Finally sighted target in the periscope, bearing about 230° T,
range about 5000 yards showing about a 30° starboard angle. Came
left to course 245° T to close the range. Target appeared to be zig-
zagging but it was difficult to ascertain the angle on the bow. The
next observation showed about a 60° starboard angle at a range of
about 2500 yards. Sound had been following the target down and
reported he was making 165 r.p.m.'s. The T.D.C. finally indicated
that he was making about 12 knots. Decided to fire a 2° later.
Spread as target was now definitely identified as a KUMA class cruiser.
With the range about 1000 yards a 90° port track with a 20° left
angle, commenced firing. Number one torpedo tube fired. The word
was given for tube number two and word was given to "fire two". Number
two did not fire and the word was passed to fire it by hand and an
attempt had been made to fire it from the conning tower. They
fired by hand, in the mean time the target had turned left and
up. Target seemed to steady and started to cross our bow. Gave
set up to the T.D.C. bearing 25 angle on the bow 110° starboard
about 1500 yards. Checked the T.D.C. solution and fired on about
120° track using a 45° gyro angle, speed 12. Torpedo left the tube
and was seen to take its angle but it was obvious it was going to pass
ahead as the target was turning left. It was now too late to give a
new T.D.C. set up so ordered number four tube set for a zero gyro
and swung the ship to the right slowly. Set the periscope on a
bearing of 12° and as the crosswire lined up with the center of the
target, fired number four tube. Torpedo went out about the proper
bearing and could be heard converging on the screws. The target

meantime was turning left and presented about 150° starboard
for the torpedo. None of the torpedoes hit. The target made a
wide sweep to the south and disappeared over the horizon making
high speed. A check later showed that the firing circuit panel in
the conning tower had flooded through a leaky cable and the
circuit solenoid wire which is in series between the firing
had parted between number one and number two tube. The light
the buzzers worked on number 2, 3 or 4 tube and these tubes had
to be fired by hand. These circuits had been checked two days
and were found to be satisfactory. It is still not known why
man on the phones could not hear the order to "fire two" unless
there were excessive air noises from the use of the poppets. All
torpedoes were heard to run hot at a depth setting of 10 feet. All
hands feel this was a golden opportunity missed and are very much
depressed.

March 2, 1942. At 0558 at Latitude 6°-10'S Longitude 112°-27'E
sighted 3 ships on the starboard bow bearing about 350° T distant
about 4 miles showing about a 70° starboard angle. Submerged
swung toward them with full rudder. Received report that both
engine exhaust valves were leaking badly. Observed a destroyer
heading toward us showing about a 10° starboard angle. Leaking
so bad that it was necessary to operate both the trim and drain
to keep water down. We submerged to 170 feet in about 200 feet of
water still running as silently as possible considering that both
pumps were running. Did not want to bottom as we would still
have to use the pumps but would be unable to use our sound gear. The
destroyer dropped 4 depth charges which shook us up considerably. No
other screws were heard.

March 2, 1942. At 2235 at Latitude 5°-30'S Longitude 112°-25E
sighted 4 ships which appeared to be 2 destroyers and 2 transports
about 140° T distant about 4 miles on course about north. Submerged
and changed course to 040° T to head in for an attack. Could not
pick up the targets by periscope but sound picked them up bearing
about 115° T. Finally picked up a screening destroyer showing about
a 10° port angle which started making high speed. Submerged to 150
feet and manned stations for depth charge attack but none came.
the destroyer passed astern. Came to periscope depth but could not
see any targets. Sound reported they could hear something bearing
about 310° T. Changed course to 310° T and could finally just make
out 2 ships showing about 140° port angle at a range of about 5000
yards. No attack.

March 2, 1942. At 2355 while submerged on course 180° T sound
reported screws on our starboard quarter bearing about 315° T. Sighted
2 destroyers on course about south distant about 3 miles. They
passed from sight making about 18 knots and may have been the escort
destroyers previously sighted.

March 4, 1942. Sighted single ship bearing about 030° T distant
about 4 miles showing about a zero angle. Submerged on course 080° T.
Sound picked up high speed screws bearing about 020° T and a ship
which appeared to be a destroyer was sighted heading toward us at
high speed. Submerged to 170 feet and prepared for depth charge
attack. Sound lost target which had apparently stopped to listen.
Came to periscope depth and looked around and nothing was in sight
and we are unable to ascertain just what became of target.

March 5, 1942. At 0228 while changing course to 280° T sighted
a ship bearing about 020° T distant about 5 miles, showing about a
10° port angle. Submerged to periscope depth and at Latitude 06-35S
Longitude 112-35E sighted a large ship through the periscope bearing
about 13° T and coached sound on. Sound picked up another set of
screws or a screening destroyer forward of this bearing. Made
the forward tubes and commenced the attack using a T.D.C. solution.
Gave periodic periscope bearings and had a good T.D.C. solution.
When gyro angle was zero fired No. 1 tube to hit on 117° port track.
Fired No. 2 tube to hit on gyro angle of 358° and 119° port track [HANDWRITTEN: (2)]
at an estimated range of 1500 yards. Torpedoes were set for 10
feet and sound heard both torpedoes run hot in the direction of the
target. One minute and twenty seconds after firing there was a
terrific explosion but it was difficult to tell where the torpedoes
hit on the target. The explosion was so loud that it could have
been possible for both torpedoes to have hit as they were fired
about six seconds apart. The target appeared to be a KATORI class
cruiser. There was a large high bridge structure, a large single
stack then quite an open space over the catapult to the structure
around the mainmast. Then what appeared to be a large turret aft
from there the deck appeared to be practically clear for a long
length to the stern. Sound reported the destroyer had speeded up and
was coming in. Submerged to 170 feet and changed course to 355° T.
We were drawing aft and apparently the destroyer was running down the
torpedo tracks. When a little on the port quarter he started to
go very deliberately and dropped a total of 7 charges which seemed
very close and shook up us a great deal. These charges stopped the
4 battery blower, knocked off a great deal of paint, took some water
through the conning tower door and by gauge lost about 1000 gallons
of fuel from expansion tank. Searching destroyer crossed astern and
circled back dropping 2 more charges when astern. These last charges
must have been 1500 yards astern but we were badly shaken. Either
these charges are much stronger or the effect is much worse in
shallower water.

March 6, 1942. At 0103 while on course 270° T sighted 2 ships
which appeared to be destroyers showing about a 70° starboard angle
bearing 250° T distant about 3 miles. They appeared to be searching
the area of last nights attack. Changed course to 340° T and searched

area with the periscope and sound listened for them but they were
not seen or heard again.

March 6, 1942. At 2215 shortly after trying to call and
transmit sighted a destroyer bearing about 010° T distant about 3
miles showing a zero angle and coming in fast. Submerged to 140
feet and prepared for depth charge attack. After submerging
could not pick up the target which had either stopped or turned
away. This ship probably did not see us as we were on course
at the time and were practically bows on and he was probably
equipped with radar or we had been cut in by our radio or both. [HANDWRITTEN: 1/2]

March 10, 1942. At 0235 while entering the passage south of
Sangeang preparatory to passing through Sape Straits sighted
patrolling destroyers heading out toward us. Turned north and
observed the challenge of another submarine bearing about 330° T
distant about 3 miles. Replied but sub had submerged. Patrol
DD's continued to circle around in the south passage. [HANDWRITTEN: 1/2]

March 10, 1942. At 0340 swung around the north side of Sangeang
and picked up another destroyer patrolling east of Sangeang. Conditions
were very poor for an attack, too light for a surface attack
and too dark for an attack submerged. [HANDWRITTEN: 1/2]

March 12, 1942. Attempted to enter Alor Straits and was just
rounding the point into the channel when a patrol vessel which
apparently lying to off the point picked us up and came charging
out. Submerged and prepared for depth charge attack but none.
Sound could hear the screws searching aft and along our port side
but evidently he could not pick us up. [HANDWRITTEN: 1/2]

(1) Major defects and casualties.

At the time of starting patrol No. 1 main engine was out of
commission due to the lub oil cooler. This cooler which had been
leaking was repaired by tender but was not tested and was in the
process of being installed and assembled on board. No. 4 main
engine was out of commission as the work of replacing a piston
and rod of No. 1 unit of this engine had not been completed.

February 20. A bad leak developed in the starboard air
conditioning unit. The leak was located and repaired but the gas
was lost in this unit and it is out of commission. The entire
system had been checked by tender personnel.

February 21. The section of stern plane shafting recently
repaired by tender personnel failed at a weld. The shafting was
temporarily repaired so that it is possible to operate the planes
with hand power and indicate the proper angle on the stern planes.

February 22. Completed the installation and assembly of No.
1 main engine lub oil cooler which was recently repaired by tender
personnel. The cooler leaked under a 6 lb. test but when the engine
was actually run it was estimated that it was leaking about 150
gallons of lub oil per hour and that it would be impossible to use
this engine unless the leak could be reduced to a point where it
would be possible to catch the oil and return it to the sump tank.
Enclosed the outer shell with a backing and rammed it up tight
with a mixture of toilet paper and rags saturated in shellac and
glypthol. This was permitted to dry and harden but upon test
the leak was almost as bad as before. The whole casing seems
to be porous.

(j) General remarks.

[HANDWRITTEN: 24 Feb]
<u>Contact on February 24.</u>

After thoroughly reviewing the situation as it then existed it
now appears that the better tactics would have been to dive
immediately the target was sighted and make a periscope approach
on the target. At the time of sighting the visibility was good,
as the moon was out and the visibility was very good. The desire
to turn toward and close the range on the surface was prompted by
the fact that we had been on the surface only about 20 minutes,
the battery was low and the desire to make an aggressive attack.
At the time of sighting the distance to the track was not over
2300 yards so it would have been possible to have attained an
excellent firing position had we been able to dive immediately
undetected. As it turned out we were illuminated, forced to dive,
depth charged, the target turned away and the opportunity for a
successful attack was lost.

[HANDWRITTEN: 25 Feb]
<u>Contact on February 25.</u>

As this situation is reconstructed it is now felt that it would
have been better to have fired on this target entirely by sound.
The sea was calm and the moon bright and each periscope observation
probably left a feather which assisted the target in turning on
us on several occasions. As the target was making high speed at
the time it was probably impossible for him to have obtained any
sound bearings and the periscope was undoubtedly the give away.
The decision to fire by periscope was based on an analysis of the
situation that had arisen the previous night. Undoubtedly it would
have been better to have waited longer before firing the torpedoes
but at the time it was felt that although the track was small it
was the most favorable that had been presented. Had we fired
entirely by sound it is now felt that we could have fired on a
desirable track at a much shorter range. In any event I am
convinced that the only way to get in an attack at close range on
these clear bright moonlight nights is to submerge as soon as a
target is sighted otherwise they sight us about the same time and
either turn away or charge in showing about a zero angle on the
bow.

[HANDWRITTEN: Bu Ships]
The proper functioning of the air conditioning system cannot be
stressed too greatly. Throughout this patrol the boat was damp and
musty. Everyone perspired a great deal and there were several
cases of heat rash and a few cases of mild heat prostration. The
crew could not get the proper sleep and night blindness was seen
even amongst the best lookouts. Fortunately the officers were able
to see satisfactorily as they had vitamin pills of their own. It is
recommended that an effort be made to supply vitamin pills to
on patrol in sufficient quantities to keep the lookouts up to
standard as night blindness is a serious handicap to a successful
patrol.

Ships using Alor Strait should regard the note in the Coast
Pilot concerning being sucked in toward the coast. When forced to
submerge just north of Alor Straits we were steering a course of
340° T but were carried toward the coast and actually made good
a course of about 300° T.

Depth charges in water about 210 feet deep were much more
severe than those previously experienced in deeper waters at
apparently closer ranges.

It is suggested that submarines operating in close proximity
and those enroute keep their TBS receivers out in in case another
desires to verify recognition or transmit.

                                        2. Weather.

        The weather was generally good throughout the patrol. Sea
was rough at the beginning but was calm after passing the barrier.
Weather in the South China Sea was excellent. The moon was up
most of the time and visibility was generally excellent. There
were quite a few rain squalls and the sky was practically always
cloudy along the horizon. Most of the time the sea was flat calm
and this tended to make periscope approaches difficult and
increased the possibility of being sighted by planes. It is
probably necessary to submerge to about 170 feet to avoid being
sighted by planes in this area.

        On the return trip encountered some rough weather south of
the barrier.

SECRET 3. Tidal Information.

In the South China Sea the currents are variable but in
the southern part the set generally seems to be between 150°T
and 200°T and the drift is as much as one and a half knots.
Frequent cross currents are encountered submerged and it was
nearly always possible to find a layer between 120 feet and 170
feet. Sometimes it was necessary to flood water in deep and to
pump it out as we neared the surface. These conditions
varied with different areas. Submarines operating in this area
should predetermine these conditions in case they are suddenly
forced to go deep.

Encountered extremely heavy set to the westward near
Sibbalds Bank. This was sufficient to move us about 12 miles
to the westward in about 4 hours and set us over toward Aurora
Bank.

South of the barrier to latitude 20 the current set to the
west about ½ knot. South of latitude 20 we encountered about
½ knot set to the eastward.

1136, 22 May, at Lat. 8-12N, Long. 108-13E, sighted the
tops of the masts of a fairly large merchant vessel bearing
340°T showing about a 90° starboard angle at a range of about
15,000 yards. Went to battle stations submerged and changed
course to 040°T. Estimated target course 060°T and appeared to
be headed toward Manila. Ran at standard speed for one hour but
was unable to close the target. At 1230 it had completely
disappeared. Could not identify the target as we never saw more
than the tips of the masts, however, there was a large crows
nest at the top of the foremast.

2107, 25 May, at Lat. 10N, Long. 110E, sighted a column of
smoke on the horizon bearing 190°T. This was later identified as
the cruiser YUBARI escorted by two destroyers. Commenced attack
and hit it with four torpedoes and sank it.

1947, 28 May, at Lat. 9N, Long. 111E, sighted column of
smoke on the horizon bearing 036°T. Target was about a 7000
ton freighter. Fired three torpedoes and got two hits. To
expedite sinking fired two more torpedoes but both missed.
Target sank about 2300.

1905, 29 May, at Lat. 8-53N, Long. 111E, sighted a destroyer
crossing our stern on course 160°T, speed about 17 knots at a
range of 4500 yards.

0010, 30 May, at Lat. 9-04N, Long. 110-52E, sighted smoke
bearing 260°T. Commenced attack on freighter target similar to
the Samarung Maru (#321). Did not get within a satisfactory
firing range.

0932, 30 May, at Lat. 8-57N, Long. 110-31E, sighted a
destroyer dead ahead showing about a 90° starboard angle on
course about 350°T, speed 17 knots at a range of about 5000 yards.

0137, 31 May, at Lat. 8-30N, Long. 110E, sighted a
destroyer bearing 225°T, distant about 12,000 yards on course 350°T.
Submerged and sound picked up high speed screws but they faded
quickly as though they had stopped. Although the visibility was
good the target was not sighted through the periscope.

2230, 31 May, at Lat. 7-52N, Long. 109-15E, sighted a
destroyer bearing 265°T at a range of about 10,000 yards. It
appeared to be making high speed on a course of about 120°T.
Target was sighted through the periscope about 6000 yards
to port but sound never did pick up the screws.

2255, 1 June, at Lat. 8N. Long. 108-50E, sighted a destroyer
on starboard bow bearing about 020°T on course about 180°T at
range about 10,000 yards. Target was pinging and making high
speed. Submerged and target passed abeam to starboard at a
range of about 6000 yards. This destroyer apparently reversed
course as it was again sighted upon surfacing. Sea was like a
mirror and precludes the use of the periscope.

0715, 4 June, at Lat. 8N. Long. 108-47E, sighted destroyer
bearing 330°T, distant about 8000 yards on course about 140°T
making high speed. Sound of screws died out bearing 110°T.

Plane circled ship several times and sent message that there was
a U.S. ship about 100 miles north of our position.

1014, 2 June, sighted reconnaissance plane type 98 apparently
flying out from Saigon on course about 125°T, elevation about
4000 feet, distant about 10 miles heading directly toward us.

0925, 22 June, sighted PBY patrol plane bearing 100°T,
altitude about 1000 feet, distant about 5 miles on course about
north. Plane changed course and came in abaft the port beam.
Exchanged recognition signals, plane circled once and continued
on patrol.

1355, 22 June, sighted PBY patrol plane bearing 200°T,
altitude about 1000 feet, distant about 6 miles on course about
south. Plane sighted us and changed course toward, circled ship
and exchanged recognition signals.

7. Particulars of Attack.

2107, 25 May, at Lat. 10N, Long. 110E, sighted what appeared
to be a column of smoke on the horizon bearing 190°T. Smoke
seemed to be pulling to the left so came right to course 190°T,
secured the battery charge and went ahead standard speed on 2
engines. The target bore about 190°T and was showing about a
zero angle on the bow. Sound could hear echo ranging on the
15,000 yard scale. The moon was up about 3/4 full and visibility
was excellent, the sea was very flat. When the range had closed
to about 16,000 yards submerged and went to battle station.
Finally picked up the targets in the periscope bearing about 190°
T still showing about a zero angle. The target appeared to be
a large high freeboard single stack man of war with a smaller one
on each quarter. The target was now pinging regularly on the
10,000 yard scale and seemed to have picked us up. Changed
course to 180°T to open the distance to the track slightly. At 2224
sound picked up screws bearing 166°T. Target had not changed
course and was making about 10 knots and was now showing about a
port angle which put us about 1200 yards of the track. At 2225
changed course to 118°T to come in on a 70° track for a 20°
bow shot. We had heavy heads in tubes numbers 2 and 3. In
order 1, 2, 3, 4 by the "white light method" match pointers with
which the approach officer changes the point of aim with the
end the TBT. The TDC operator matches pointers with the
solver target bearing pointer without stopping the solution
problem. When sound bearings indicated we were about on the
firing bearing, raised periscope matched pointers and commenced
firing at 2230. Aimed the first shot just inside the bow, the
second at the bridge, the third just abaft the stack and the
fourth at the stern. The range appeared to be about 1000 yards.
Torpedoes were set for depths of 10, 8, 8 and 10 feet respectively.
Swung the periscope around and was trying to locate the escorting
destroyers when the first torpedo was heard to hit after a
second run. Swung back to the target and saw the agitation of
the first shot near the bow, saw the second shot hit under the
bridge, the third just abaft the stack and the fourth well aft on
the stern. It was easy to distinguish the second and third
which were the heavy heads because they shot a column of
water well above the masts and gave off about twice as much
smoke as the smaller heads. Sound heard the destroyer
speed up to high speed and commence continuous echo ranging.
Submerged to 200 feet and changed course to 200°T, ran silent,
set stations for depth charge attack. Destroyers started
dropping depth charges. There seemed to be very heavy charges and
us up quite a bit considering that they must have been at
1000 yards away. Destroyers could be heard pinging and running
at high speeds for intervals and then stopping. Bearings
of the bearings came forward of the beam. The target which was
a large single stack war ship which was much larger than the
destroyers was separately identified from "Janes" by three

different persons who saw it at close range as the cruiser
YUBARI, however it appeared to be much longer than the length
listed. When last seen the target appeared to be settling
rapidly. Shortly after submerging a muffled explosion and
considerable water agitation was heard on the bearing of the
target. It should be noted that sound was getting a turn on
between 140 and 160 but the target could not have been making
over 10 knots. This is the second time this condition has
been found to exist with cruisers.

Time: 2230, 25 May 1942.
Location: Lat. 10N, Long. 110E.
Type: Cruiser YUBARI.
Attack: Night submerged by periscope.
Target: Course 008°T, speed 9 knots, range 1000 yards,
76° port track. Points of aim bow, bridge,
aft of stack and stern. Target did not maneuver
to avoid.
Torpedo: Fired four. Numbers 1 and 4 set for 10 feet,
numbers 2 and 3 for 8 feet. Keel depth 59 feet.
Gyro angles 352, 353, 353, 354. Run 950 yards.
All were heard to run.
Fire Control: TDC, white light method match pointers, assisted
by sound.
Results: Four hits - sunk.

At 1947, 28 May, at Lat. 9N, Long. 111E, sighted smoke on
the horizon bearing 036°T. Smoke seemed to be pulling to the
right so changed course to 040°T. Range was decreasing out of
smoke. At 2008 submerged and picked up the target in the peri-
scope. Sky was completely overcast but as moon was full the horizon
was very distinct. Target was showing a small port angle. So
picked up screws bearing 056°T. At 2028 changed course to 008°T
for a straight bow shot, 70° port track at a range of 1000 yards.
Decided to fire three torpedoes, firing order 2, 1, 3. Number
2 and 3 were light heads set for a depth of 10 feet and No. 1
was a heavy head set for 8 feet. At 2035 commenced firing by
white light match pointer method. Points of aim, No. 2 inside
the bow, No. 1 at the bridge and No. 3 abaft the stack. Estimated
speed 10 knots, range 1000 yards. One minute after firing
torpedoes numbers 1 and 3 hit amidships. No. 1 which was the
heavy head hit just abaft the bridge and No. 3 hit just abaft
the stack. All torpedoes were heard to run but No. 2 must have
missed ahead. Ship stopped and there was much scurrying around
on deck with flashlights, boats were being lowered. Ship began
to settle by the stern and took about a 20° starboard list. As
ship was not going down very fast decided to give him one more

and target had pulled slightly to the right. At first the
silhouette looked like a submarine but after recalling the ship
identified it as a small freighter. Target appeared to change
course to the left radically so came to course 358°T and sped
up. As sea was flat calm and visibility excellent did not wish
to use the periscope any more than absolutely necessary. So
followed the target along and when the firing bearing was come
on slowed down and raised periscope. Had expected the range to
be about 1000 yards however it had increased considerably and
was about 4500 yards. A plot was being run but this change did
not show up. The target appeared to make a radical change to
the right so changed to course 055°T and again attempted to close
the track but the range was never reduced below 4000 yards. The
movements of this target were peculiar. The last change of
course headed him about toward Rifleman Bank. Ship was either
a decoy or was attempting to locate survivors from the ship
sunk in this area the previous night. Inasmuch as we had only
six torpedoes forward did not consider it advisable to shoot
at him at the ranges attained. Target was similar to the
SAMARANG MARU (#321).

8. Enemy Anti-submarine measures.

Planes and destroyers were searching the area during the
period 28 May to 5 June. Planes apparently left Saigon and
made triangular runs toward Vanguard Bank. Destroyers
patrolled singly at high speed using echo ranging. They
apparently were operating out of Camranh Bay patrolling day and
night on course about 150°T and reverse covering strips about
10 miles wide.

Echo ranging was not very efficient as they should have
picked us up several times.

9. Major Defects.

1905, 4 May. Stopped battery charge due to full voltage
ground. Found to be in the control unit for cook-
ing range. Cleared and continued charge.

0200, 5 May. While inspecting No. 1 main engine after the
battery charge it was found that the piston rod of #7 unit was
discolored and slightly scored. The rod and piston
plunger had to be removed. Trouble was caused by an overlapping of segments
of the spring retained wiper ring. There had been no blow by the stuffing
box and the rod after being honed can be used again. This
is the first casualty with the oil cooled stuffers.

0700, 7 May. Valve in air starting block #3 main engine
stuck.

1250, 8 May. Casualty to drain pump. Upon examination it
was found that the connecting rod to the forward plunger had
broken and the end of the rod had driven a hole in the stuffing
gland. No spare rods are carried so a section of the rod was
manufactured and inserted between the broken ends. After
reassembly it was found that the crank shaft was bent. It was
necessary to straighten the crank shaft and take a cut on the
journals. This is a major repair well done and credit deserves
much credit.

0845, 18 May. Casualty to No. 1 I.C. motor generator. Slip
ring connection broke off and touched opposite slip ring causing
a ground.

21 May. While servicing torpedoes discovered that the
gyro spindle of No. 1 torpedo tube was stiff and working hard.
Disassembled and found the worn spindle bearing had come apart
permitting the ball bearings to fall down into the gears and
bind them. Renewed bearing and spindle operated satisfactorily.

0800, 26 May. Examination revealed that the babbitt band of
No. 1 piston, No. 4 main engine, was loose and several pieces
were missing. Pulled piston and renewed piston stuffer.

2330, 28 May. An examination of the torpedoes from the
from the deck tubes revealed that on three of them the warhead
bulkhead in the exploder mechanism recess was so badly crimped
and distorted that the exploders could not be fitted at the first
opportunity. The only explanation for the damage to the two that
torpedoes had been placed in the deck tubes with about 500# air
pressure in them. Two of them had leaked sufficiently to build
up a pressure in the tubes and blow the lugs, air pressure in the heads could not escape
the outer doors. All torpedoes were then tied down and when
lugs blew, air pressure in the heads could not escape too fast enough.

10. General remarks.

Started the patrol with four men on the sick list as
follows:
    Tonsillitis - Cleared up after about 1 week.
    Broken ribs - Strapped up most of patrol, still bothers
        some.
    Badly infected arm - Cleared up after about 2 weeks.
    Badly infected leg sores from scratched bites - Drained
        most of cruise, nearly cleared up.

9 May. With the forward air conditioning unit out the
magazines attained temperatures of 95° and 97°, the highest
recorded in three years.

In the China Sea area about 25 fathoms of water seem to be
required to avoid detection by aircraft due to the clear
character of the water and bottom.

Large quantities of logs and floating debris were
encountered throughout the patrol. This was particularly noticeable while
running on the surface south of the dangerous ground during
daylight. Although many of the logs were large it was
practically impossible to see them at night as they were discolored
and partially submerged.

A satisfactory location for the searchlight has not been
determined since the removal of the A frames and handling the
aircraft recognition has become a problem. If submarines were
equipped with the portable aircraft signal lamps, which are
bright enough to be seen it is felt that the problem would be
solved.

Fuel and miles steamed, 3 May - 24 June:
(a) Miles on surface - 7705.6 miles
(b) Hours submerged - 543.1 hours
(c) Fuel used - 70011 gallons
(d) Lubricating oil used - 2425 gallons

2. Weather

The weather was generally good throughout the patrol.
The patrol started and ended with the moon about 1/2 full.
Skies were generally overcast and some rain was encountered
south of the barrier.

On station the weather was variable with skies overcast and
intermittent rain squalls, with heavy clouds along the horizon.
Winds would come up suddenly and blow strong and seas would get
rough with large swells. This would be followed by a calm for
several days and the sea would become glassy flat.

3. Tidal Information

The current from Cape William to Sibbalds Bank sets in a
generally SW direction and the drift varies between 1/2 to 1-1/2
knots. Near Sibbalds Bank there is a strong westerly component.

Sibutu Passage the flood sets to the NE and the drift is
between 1 and 2 knots depending on the state of the tide. South
of Sibutu there is a prevailing westerly component that seems to
rise to about 2 knots at the height of the ebb.

In Balabac Straits the ebb seems to be to the SW but did not
appear strong. West of Balabac and South of Palawan there is a
prevailing SW current the strength of which seems to vary between
1/2 and 1-1/2 knots.

Encountered layers and cross currents which made steering and
depth control difficult in the following localities:

South of Lombok Straits
West of Sibbalds Bank
West of Cape Mandar
South of Sibutu Passage

4. Navigational Aids

No navigational lights were sighted North of the Barrier.
Positions were determined from several prominent mountain peaks
which are marked on the charts and are familiarly known.

Balabac Peak which is the highest and most prominent peak
on Balabac Island is useful in locating the entrance to Balabac
Strait. While transiting the strait Nasubata Island is easily
mistaken for a ship.

7. Particulars of attack.

0645 7 August. At Latitude 7-33N, Longitude 116-04E, sighted
     what appeared to be smoke on the horizon bearing 228°T.
     As the bearing of the smoke appeared to be pulling to the
     right, changed course to 000°T and speeded up.

0715 Bearing was about constant so changed course to 320°T. The
     tops of the target were now visible and it was estimated
     that it was on a course of about 040°T making about 10 knots.
     Went to battle stations submerged.
     At first decided to shoot a straight bow shot on about a
     70° starboard track but as the angle on the bow was now
     small decided to cross his track and shoot a stern shot.
     Slowed to minimum speed and crossed track of target which
     showed that he was on a course of about 038°T.

0758 Decided to fire three torpedoes by the white light method
     spread on a 70° port track straight stern shot. Changed
     course to 330°T.

0820 When the range was 1500 yards and the distance to the track
     was about 1200 yards commenced firing the after tubes No. 5,
...  No. 6 and No. 8 using an eight second firing interval. All
     torpedoes fired were light heads set for six foot depth and
     were heard to run in the direction of the target but all
     missed. Points of aim: bow, center and stern.

0822 After these torpedoes apparently missed, decided to fire No.
     7 tube which was a heavy head set for a depth of six feet.
     Fired No. 7 tube at the center of the target by the white
     light method. This torpedo was heard to run toward the
     target but did not explode.

0826 While changing course to decrease the range and to bring
     the bow tubes to bear, the target speeded up, changed
     course toward and commenced firing about a four inch gun
     mounted in the bow. Two depth charges were dropped at this
     time.

0828 Submerged to 170 feet. From changes in sound bearing target
     was apparently zigzagging.

0832 Came to periscope depth and observed target heading directly
     away at high speed on course 040°T at a range of about
     4000 yards. Changed course to 040°T and commenced trailing
     but target pulled away and disappeared over the horizon.
     The target was a whale factory similar to the Nisshin Maru.
     The bridge was well forward with a gun mounted
     forward of the bridge. There were two sets of goal posts
     with a deck house amidships. The engines with two
...  athwartship stacks were aft. After firing, men wearing life
     jackets could be seen running in all directions on deck.

(7. Particulars of attack (Cont'd.)
No definite reason for the misses can be given however it is felt
that it was due to a control error and that the torpedoes did not
go out on the proper gyro angles. This may have been due to some
error in the TDC at the instant of firing or the failure of the
gyro setting mechanism to set the proper angles. The TDC had been
worked out and tested daily and had been operating per-
fectly. The problem has been set up and run through the TDC several
times but we have been unable to come out with a solution which
gives the gyro angles that were set on the first three torpedoes.
The last torpedo fired, according to a replot and all the informa-
tion available should have hit, however the miss may be attributed
to a change in speed and a possible change in course which was not
detected at that time.
The tracks of the torpedoes were not observed but about twenty sec-
onds after firing a film of light blue smoke formed along the sur-
face of the water and covered an area in front of the target along
its entire length.

Time: 0820, August 7, 1942.
Location: Lat. 7-33N, Long. 116-04E.
Type of target: Whale factory.
Attack: Day submerged by periscope.
Target: Course 038°T, speed 9 knots, range 1500 yards. Track angles
84°, 85°, 85° and 102° port. Points of aim bow, amidship,
stern and amidship. Target maneuvered to avoid.
Torpedoes: Total 4. Three by spread and one separately. All torp-
edoes were set for a depth of 6 feet. Keel depth 58 feet.
Gyro angles 177, 175, 173 and 154. Run about 1200 yards,
all were heard to run.
Fire control: TDC white light method divergent spread.
Results: Torpedoes missed.

8. Enemy A/S Measures

The only target encountered adopted the following tactics after
it had observed that torpedoes had been fired. Increased speed
and turned toward. About a 4 inch gun mounted in the bow forward
of the bridge was trained and fired in the direction of the
periscope, the flash of the gun was observed but the fall of
shot was neither seen nor heard. Two depth charges were dropped.
It is believed that throwers must have been used although these
were not seen.

9. Major Defects.

On two occasions the bow planes could not be rigged in upon
surfacing. It was found that the failure was due to the improper
adjustment of the electrical tilt stop.

2200, August 2, secured No. 1 main engine because of bad leak
in patched lub oil cooler. Cooler opened up along the old crack
in the casing which had been soldered and was losing so much oil
that it was not considered practical to operate this engine. A
message to this effect was sent to CSSWP.

0210, August 9. The gyro compass was erratic and it was
necessary to place it out of commission and replace a faulty
follow up motor.

1708, August 9. Upon surfacing the main induction valve stuck
and failed to open with power. Thoroughly greased and worked out
the mechanisms with hand and power but it failed to open to the
later on power. The next day it operated properly.

0315, August 10. Stopped the auxiliary engine to check a
pounding noise in the generator end. It was found that all of the
bolts connecting the fan flange to the coupling were sheared and
there was considerable back lash in the flexible coupling. It was
found that 3 out of 4 of the special coupling bolts were sheared
and that 7 of the special bushings were broken or damaged so badly
that it will be necessary to replace them. As these are special
fittings and no spares are carried the auxiliary engine will be
out of commission for the remainder of the patrol.

Experienced considerable difficulty with many valves especially
in the high pressure air system. The condition is considered bad
as the seats have been ground down and many valve discs have been
cut and ground so many times that on a great number of them it
will be impossible to take another cut to prevent them from leaking.

0400, September 3. The compensating line in the forward battery
compartment blew out and allowed some water to leak into the for-
ward battery. The hole was patched but is indicative of the poor
condition of these lines and it is recommended that the main
trim and compensating lines, all of which have leaks, be renewed
at the first opportunity.

Leaky exhaust valves were a source of constant trouble during
the entire patrol. Fortunately sea conditions were such that it
was possible for men to go down on deck and grind them in about
every other day. On two occasions upon submerging the leaks were
considered so bad that it was feared that the pumps would be unable
to handle the quantity of incoming water and it was necessary to
surface immediately to grind the valves before again submerging.
The seriousness of such a condition is at once apparent and the
need of a satisfactory inboard stop valve cannot be over emphasized.

10. Remarks.

The health of the crew was generally good. At the start of the
patrol there were a great many colds and there was a regular
epidemic of serious coughs that had many of the symptoms of
whooping cough.

The consumption of fresh water was high but ample potable and
battery water was made and was not a limiting factor.

Radio reception was good except between 0300 and 0430 during
which time VIXØ was difficult to copy due to weak reception. "Bells"
was strength 3 to 5 and could be received and copied. No difficul-
ties were encountered in transmitting to VIXØ.

Sound conditions were very good and there were fewer water
noise interferences than heretofore.

Radar was not used except south of the barrier. Vibration
caused some trouble with the receiver and transmitter. Results
so far have not justified its installation.

Subject: U.S.S. SALMON (SS182) - War Diary of Fourth War
Patrol, period July 21 to September 8, 1942.

1. SALMON spent forty-eight days at sea on this patrol
and it is disappointing that she had only one contact throughout
this period. It is more disappointing that failure to sink or
even damage this valuable target under ideal elementary conditions
was evidently due to personnel failure in the operation of the
T.D.C. which caused torpedoes to go out on wrong gyro angle and
pass astern of the target.

2. The numerous material defects, especially the con-
stantly leaking exhaust valves, seriously lessened the military
effectiveness of the vessel. Leaky exhaust valves are character-
istic of Electric Boat Company submarines of this Squadron and
the condition should be rectified by design alteration during
next Navy Yard overhaul.

3. A submarine thought to be friendly was sighted on
August 26, 1942. After being challenged the submarine turned away
and submerged. Submarines of this Squadron have been advised to
avoid submarines thought to be friendly. If it is a friend, no
purpose has been served by challenging, whereas if it is an enemy
the advantage of surprise has been lost.

1. Forwarded.

2. Only one enemy vessel was sighted by the SALMON on
this patrol in PALAWAN PASSAGE where previously two oil tankers
had been sunk and two others damaged. It is possible that the
passage was not being used by the enemy during the period of
SALMON's patrol for this reason. For the present this passage
will be visited enroute only by some of the submarines returning
from patrol along the INDO-CHINA coast. In this way it will be
covered at irregular intervals.

3. Three misses on the only attack made by SALMON, due
to improper operation of the T.D.C., again illustrate the need
of constant training for the entire torpedo control party.

4. Submarines of this force are now instructed not to
make recognition signals when in enemy controlled waters.

## The Story of the First Thanksgiving: A Harvest of Gratitude and Unity

The First Thanksgiving, a pivotal moment in American history, represents a unique blend of cultural exchange, survival, and gratitude. It was a harvest festival held in the autumn of 1621 by the Pilgrims of Plymouth Colony, joined by members of the Wampanoag tribe. This event, though often romanticized, was a complex gathering born out of necessity and a fragile alliance.

**The Pilgrims' Arrival and Hardship:**
In September 1620, a group of English Separatists, later known as Pilgrims, set sail from Plymouth, England, aboard the Mayflower. Seeking religious freedom and a new life, they endured a perilous 66-day journey across the Atlantic. They landed in what is now Plymouth, Massachusetts, in December 1620, a harsh and unforgiving wilderness.

The first winter was brutal. Unprepared for the severe New England climate, lacking adequate shelter and food, nearly half of the 102 colonists perished from disease, starvation, and exposure. Their survival hung by a thread.

**The Wampanoag's Role:**
As spring arrived in 1621, the remaining Pilgrims were weak and desperate. It was then that they encountered the Wampanoag people, the indigenous inhabitants of the land, led by their sachem (chief), Massasoit. The Wampanoag had lived in the region for thousands of years, possessing invaluable knowledge of its resources and seasons.

7. Particulars of Attack

4 November, 0815. At Latitude 20-14N, Longitude 120-13E
Sighted smoke of convoy bearing 015°T distant about 14000
yards. Changed course to 060°T heading about for Luzon Point
and went ahead standard speed. Sound could hear echo ranging
but no escort vessels could be seen.

0845 Slowed and took an observation and sighted 4 cargo vessels in
column with a destroyer of the SHIGURE class ahead of and
inshore astern of the column. They were on course about 165°T
speed 12. The first 3 ships were about 5000 tons and the
fourth was about 7000 tons. Bearing was pulling ahead so
speed up to close.

0915 Took another observation but targets had gotten by but decided
to fire one long range shot.

0917 Fired No. 2 tube set for slow speed at an estimated range of
4500 yards. Torpedo was heard to run for a considerable time
toward the target but sound finally lost it and there was no
explosion. The wake must have been sighted as the target
appeared to change course and the destroyers started short
scale echo ranging and were sweeping the area where we fired.
We were not picked up and no depth charges were dropped.

Time: 0917, 4 November 1942
Location: Lat. 14-20N, Long. 120-13E
Type: Cargo ship - 7000 tons - 400 feet - 2 goal posts -
single stack. Target maneuvered to avoid. Convoy of
4 with 2 DD's.
Attack: Day periscope.
Target: Course 165°T, speed 11 knots, range 4500 yards, 135°
starboard track.
Torpedo: Fired one, heavy head set for 6 feet, gyro angle 60°.
Heard to run. Point of aim center of target.
Fire control: TDC. White light match pointers.
Result: Miss.

8 November, 1200. While running on the surface at Latitude
16-20N, Longitude 119-11E sighted smoke bearing 210°T distant
about 15 miles. Changed course to 210°T and went ahead stand-
ard to close. Bearing was dropping aft but range was decreas-
ing and top of masts were now visible and showed an angle of
about 80° starboard for an estimated target course of 340°T.

notes with pleasure the high percentage of torpedo hits attained
on this patrol. Of nine torpedoes fired, six hits were made, re-
sulting in considerable damage being inflicted upon enemy shipping.
This gratifying score of 67% hits would have been 75% had not one
torpedo been wasted by the firing of a single shot at a target
from a range of 4,500 yards. Any target worth firing at is worth
the expenditure of sufficient torpedoes to give reasonable ex-
pectancy of a successful attack. In this case, a torpedo spread
should have been employed or no torpedoes should have been fired.

1. The Sixth war patrol of the SALMON was the first
for the new commanding officer.

2. Good area coverage was carried out and the contacts
made in the area were above average. Unfortunately many attacks
were frustrated because of enemy anti-submarine activity and in
other cases by poor weather conditions.

3. It is unfortunate that the commanding officer
changed his decision on June 8, and chased the convoy rather than
wait. for the more valuable carrier targets that later appeared.

4. The Commander Submarine Force, Pacific Fleet, con-
gratulates the Commanding Officer, officers, and crew for this
Sixth war patrol. SALMON is credited with having inflicted the
following damage:

tack developed into three freighters with one escort. By running at
high speed it may have been possible for us to attain favorable posi-
tion for attack. However I interpreted literally my orders to remain
undetected and did not attack. After some deliberation decided that
this target was too good to miss. We would trail and attack at night
well south of the position occupied by the SCULPIN and the TRIGGER.
so at 2015 surfaced and commenced tracking at high speed. Sighted two
large shapes on the horizon at 2220. Contact #16. Con-
tact got a pip at 16,000 yards bearing 075° (T). Assuming this to be
our convoy on predetermined course of 140° (T), we came to a converging
course at high speed to close for attack. It soon became apparent
however that this target was on opposite course as range was opening
rapidly. Realized that we had contacted a carrier group so came left
to the bearing. We were able to maintain the range constant at eight-
een knots. Determined the course to be 330° (T). At 2305 and 2323
sent contact report to SCULPIN and TRIGGER. Experienced some diffi-
culty with salted up antennas.

June 9 Trailing the carrier group. At 0016 heard a loud and distant explos-
ion. At 0027 heard several distant explosions distinctly felt through-
out the ship. As we were completely out of this fight at 0100 set
course to carry out second part of special mission; running on surface
at high speed until 1600 when we arrived at estimated 2000 position
of convoy and headed south to intercept. No contact made so at 2000
opened out ten miles to westward of estimated track and commenced
search to northward and to cover the estimated down position. At
2200 received instructions to proceed on special mission. Proceeding
at high speed to arrive in position tomorrow night.

June 10 Submerged at daylight. Number three main motor has a zero ground.
Decided to proceed with port shaft only in commission. Starboard
shaft to be used only in emergency at slow speed to minimize fire
hazard. 2350 OOD reported a large shape on the horizon. Radar got
a pip at 18,000 yards. With range closed to 11,000 yards submerged

Remarks:
This convoy consisted of three large AK accompanied by two escorts
similar to our PC 451 class and one OCA similar to the one shown on page 116 of
ONI 14. The three AKs were in line with the OCA ahead. The escorts patrolled
ahead and astern; zig zags were nominal. We had plenty of time to observe and
diagnose the zig zag plan; most of the zigs were to the right. First position
obtained was favorable except for long range. The escorts presented no problem,
the entire convoy had seemed to be asleep. Just prior to firing, the convoy had
zigged left and our diagnosis of the plan indicated only a few short left
zigs, it was felt that we must accept the handicap of firing at long range. Four
bow tubes were fired at the near ship on the flank, and the boat was swung right
to bring the stern tubes to bear. Periscope exposures were infrequent and short
because of the smooth sea. As the ship was swinging, the explosion of the bow
torpedoes were heard. The first two torpedoes exploded about three seconds apart,
the second louder than the first; the third torpedo in about eight seconds. On
the next periscope exposure the second ship in line was in position and a setup
was obtained. She was a double ender and was much lower forward than aft which
gave her the appearance of being 180° off her course. On later diagnosis it
was decided that the first torpedo fired forward had missed ahead and as the two
ships were overlapped. The boat
had hit the next ship in line under the bow.
was now heavy on. Then the stern tubes were fired. We had very little periscope
exposed. I used the ICT as the point of aim. Just before firing the third
torpedo I swung rapidly to the right to observe the escort, who was heading to-
wards us, and then swung back to the target and fired the third torpedo. How-
ever, I had neglected to switch off white light, the TDC not being able to
follow, the torpedo went out with a gyro angle of 230° directly at the escort.
The explosion of the first and second torpedoes fired from the stern were heard
about two minutes after firing. Although results of this attack cannot be sub-
stantiated it is felt that one or both of these ships sank. However, in the ab-
sence of substantiation the commanding officer claims damage by two hits to one
freighter of 7,500 tons similar to page 89 of ONI 208-J, and damage by three
hits to one freighter of 6,429 tons similar to page 175 of ONI 208-J. Probable
sinking of these ships is substantiated by the sighting on the next day of only
one set of masts with the OCA.

(d) During a battery charge the Winton auxiliary engine
type 8-241 developed a pounding noise. Investigation found that
an exhaust valve in #7 unit cylinder head had apparently broken
off at the stem. The damage resulting from this was a severely
battered piston and cylinder head, a crushed injector tip, and the
destruction of the remaining exhaust valves. All damaged parts
were replaced with spares and the engine placed back in commission.

(e) #3 main motor developed a zero ground on the series

block had rubbed against a drain pipe and had chafed through the
lead sheathing and insulation. The ground was cleared by rein-
sulating the cable.

11. Radio and Radar.

     Radio reception was not complete. The following serials
were missed: 32, 33, and 83.

     Last consecutive serial received 66.
     Last consecutive serial sent 3.

     The SJ and SD radars worked satisfactorily. Good contacts
were made with the SJ at 16,000 yards. Credit for such operation is due
our radar technician who worked on the set unceasingly to keep it in operat-
ing condition.

12. Sound Conditions and Density Layers.

     Sound conditions were average to poor. Propeller noises
were picked up at ranges of from 3,000 to 5,000 yards. In the attack of
June3, sound made no contact at firing range. On May 24, water noises of a
passing convoy were picked up at 8,000 yards. The Bathythermograph showed
a negative temperature gradient consistently, the windswept layer extending
to an average depth of 100 feet.

13. Health and Habitability.

     Living conditions on board were very satisfactory in all
respects. A well balanced food ration was served. It is estimated that
twenty days provisions remained on board; however, it is not believed that
a balanced ration could have been served during this period.

     The health of the crew was very good with the exception of
the following illnesses which were not incapacitating:

     One case of Gonorrhea (chronic).
     Six cases of Vincent's Angina.
     Twenty-one cases of Gingivitis.
     Several cases of acid indigestion.

     Treatment was administered by the Pharmacist's Mate for all above with
apparent good results.

     1.    The Sixth War Patrol of SALMON extended over a
period of fifty-three days. Thirty days were spent in the area
and on special missions in the vicinity of the area.

     2.    Ten contacts were made with targets worthy of
torpedo attack, but despite a determined, aggressive attitude
on the part of the Commanding Officer, SALMON was able to
attain an attack position on only one. Low visibility
handicapped the submarine in developing three of the contacts
and anti-submarine measures forced discontinuance of approaches
on two targets.

     3.    The two attacks of this patrol were made within
five minutes of each other on two ships of the same convoy.
These attacks were conducted aggressively and skillfully,
resulting in five hits out of seven torpedoes fired. Had it
not been for an error which caused a torpedo to be fired with
an incorrect gyro angle, the score might have been six out of
seven.

     4.    It will be noted that the periscope was unusable
in high power on at least three days during this patrol. While
low visibility weather was partially responsible for this con-
dition, it appears that external fogging of the window was also
a factor.

     5.    SALMON returned from patrol in very good material
condition. The performance of the main engines, except for
excessive lub oil consumption, was very satisfactory. Attention
is invited to the fact that fuel and lub oil expenditures on this
patrol indicate that the lub oil endurance of SALMON is slightly
less than the fuel oil endurance.

Prologue:

Arrived Submarine Base Midway from Sixth War
Patrol on 19 June 1943. Commenced refit by Submarine Base
Midway on 20 June 1943. Scheduled date of completion of
refit, 4 July 1943. On July 4, 1943, a casualty occurred to
#2 main generator (fully described under major defects) which
delayed completion of refit to 12 July 1943. Conducted two
days training 13 and 14 July 1943. Observing aircraft re-
ported oil slick (see major defects under hull). Readiness
for sea date, 17 July 1943.

1. Narrative.

All times K unless otherwise specified.

17 July 1300 N Departed Submarine Base Midway for area
with surface escort until dark. Made
trim dive.

17 - 24 July Enroute patrol area. Made daily training dives,
held daily fire control drills, and conducted
general indoctrination and instruction of the
crew.

During the training dive on 21 July, the operating
gear for negative flood valve became inoperative
(see section under major defects for full descrip-
tion of casualty). During the night, with the ship
lying to with all floods closed, Lieutenant L. P.
Davis, Jr., U.S.N. and Ensign J. P. Woodling, U.S.N.
entered negative tank through number two main bal-
last tank, removed a broken section of negative
flood valve linkage, and brought it into the boat
where it was straightened and reenforced, and then
reinstalled it. This was a job well done under
difficult conditions and gave us the use of nega-
tive tank during the patrol.

2. Weather.

The fog conditions experienced along the eastern
shore of the Kuriles has been mentioned in the narrative. In
general this fog belt extended two hundred miles or more off
shore. H.O. Misc. No. 10638, Meteorological Data for Japan
covers the fog situation in the Kuriles very thoroughly and
comprehensively. Southeasterly winds were prevalent during
this period. In the sea of Okhotsk and in the lee of the
Kuriles chain good weather was encountered with excellent
visibility except in the vicinity of the passes through the
islands where fog from the other side filtered through. Of
the thirteen days spent in the sea of Okhotsk only three days
of rain and fog were experienced. Near the volcanic Kuriles,
warm air and sulphur fumes wafted down off the high volcanic
peaks were very noticeable.

The temperature on the surface was mild in general.
The extremely cold water however made the boat rather uncom-
fortable submerged. Thirty degree changes of water temperature
from periscope depth to one hundred feet were not exceptional.

3. Tidal Information.

Currents conformed in general to those described
in the coast pilot and sailing directions.

4. Navigational Aids.

The high peaks on the Kuriles and on Karafuto
made piloting and position keeping very easy. The SJ radar
was extremely useful at night for position keeping and also
for navigating in the fog. The fathometer was used to good
advantage.

Airo Misaki light was found to be burning with
normal characteristics. A lighthouse was observed to be
situated on the southern tip of Kita Shiretoko Misaki (Cape
Patience) but was not seen at night to observe its charac-
teristics. This light is not shown on current charts.

imbedded in the insulation. This was determined to be a result
of a cut in the commutator taken during the last navy yard
overhaul. The engine was used to turn the commutator while
cutting and apparently no precautions were taken to prevent
the generator fan from drawing copper particles into the field
coils and armature windings. During the last navy yard over-
haul, the top half and armature of each main generator was
removed for overhaul. The only repairs made to the bottom
half was a rather sketchy varnishing of the insulation of the
tops and ends of the field coils. Since it is obvious that
the bottom field coils are the ones whose insulation is most
likely to be deteriorated, failure to properly and thoroughly
varnish the entire series fields when the opportunity pre-
sented, with only a few more man hours of work involved, is
considered a serious oversight. In view of the above, it is
considered that the condition that was found to exist in the
bottom series field coils of #2 main generator probably exists
also in the similar coils in #1 main generator. These field
coils should be inspected when the opportunity arises for
doing so. A dielectric breakdown test is recommended.

(2) 18 July: Underway, battery charge on #2
main engine, the outboard #9 tie rod broke just above the lower
nut. The break was clean and apparently due to crystallization
of the metal. A "jointed" tie rod was installed as a replace-
ment. The lower bearing saddle of #8 main bearing showed no
evidence of displacement; however, the bearing jack bolts had
loosened. The main bearing was removed for inspection and
found to be slightly wiped. This was apparently a result of
the misalignment caused by the broken tie rod. The bearing was
renewed and the tie rod set-up to the proper tension.

(3) 28 July: The #1 lubricating oil purifier
motor apparently overloaded and caused the contactor holding
coils in the starting panel to burn out. Investigation dis-
closed that the armature of the motor has a transient "open" in
the windings which occurs only when the armature is rotated.
This "open" could not be repaired at sea and no replacement
was available aboard ship. The lube oil in #1 and #2 main
engines was purified periodically in the #2 lube oil purifier.

     (4) 19 July : While making routine 100 hour
piston ring and crankcase inspection on #1 main engine, the
following defects were found; #8 unit, all piston rings and
babbitt band missing; #4 unit, lower piston fire ring missing
and scoring of babbitt band; also generally excessive gap clear-
ances on all unit piston rings, indicating excessive piston
ring wear. Prior to securing #1 main engine it had been
noted that:

          1. Engine smoked black when heavily loaded.
          2. Scavenging air pressure had dropped to
             2.5#/in² from about 3.5#/in².
          3. Lube oil temperature 150° F with all
             cooling available.
          4. Excessive crankcase pressure as indicated
             by air bubbling up through division cover
             drains (Crankcase vents fitted with air
             maze filters by NYMI do not function).
          5. Hot white combustion flame out of #8
             upper indicator cock.
          6. All pyrometer readings were normal for
             upper and lower cylinders.

Upon disassembly and further inspection it was found that:

          1. Supercharge shaft, upper and lower, shear
             pins were not sheared and the shafts
             were properly timed.
          2. Cylinder lubricators were functioning
             properly.
          3. #8 unit piston rod worn tapered about
             .005 inch.

     During previous 100 hour check at 720 engine hours, the two
upper piston rings #4 unit were renewed because of excessive
wear indicated by excessive gap clearance. Also during Mid-
way refit period, all piston rings of #3 unit were renewed
when piston was pulled incidental to renewal of lower #3
cylinder head water jacket. The pistons in all four main
engines are of the "all-fire ring" type, Bu Dwg No SS182/S41-
08 Alt.1 (H.O.R. File No N-606-A), fitted with carbon steel
piston rods installed during NYMI overhaul December 1942 to
April 1943. The engine was repaired by renewing #4 and #8
pistons, rings, and stuffers, but was to be operated only
during an emergency. Numbers 1, 3, and 4 main engines will be
given complete piston overhaul during current refit period.

Via:            The Commander Submarine Squadron TWO.

Subject:        U.S.S. SALMON - Report of Seventh War
                Patrol - Comments on.

                1.
                The Seventh War Patrol of the Salmon covered a
period of forty days, twenty-one of which were spent in the
assigned area. Approximately nine days were wasted due to
heavy fogs. Contacts appear to be plentiful in the Sea of
Okhotsk. Seven contacts were made in eight days. Of these
contacts four attacks, two of which were successful, were
made. SJ radar was used most effectively, and the trans-
it of Uruppu Suido by use of radar and fathometer was nice
navigating.

                2.
                Attack No. 1 - August 7 - An excellent ap-
proach but unfortunately no results. With the ideal position
attained and with the accurate data, subsequently checked, it
is not clear why the torpedoes missed, except possibly the
torpedoes ran deep or erratic due to low temperatures in this
area.

                Attack No. 2 - August 8 - A well conducted
and successful attack.

                Attack No. 3 - August 10 - Another well con-
ducted attack, but an excessive number of torpedoes for this
target. This excessive expenditure was due in part to poor
torpedo performance.

                Attack No. 4 - August 13 - An unfortunate
guess presented a poor firing position. Failure to hit may
possibly have been due to circular runs. It appears that
deep submergence was sought too quickly, especially in view
of the fact that no depth charges were seen on this target.
With the calm sea prevailing it is believed the wakes of the
torpedoes could have been followed, thus gaining more conclu-
sive evidence on torpedo performance. In the event of a cir-
cular run, time would have still been available for deep sub-
mergence.

SECOND ENDORSEMENT to
SALMON SEVENTH WAR PATROL.

From: Commander Submarine Squadron TWO.
To: Commander Submarine Force, Pacific Fleet.

1.
The seventh war patrol of the SALMON was in-
telligently and aggressively conducted.

2.
The failure of some of the torpedoes to des-
troy targets is disappointing. It must be realized, how-
ever, that many factors enter into torpedo performance
ranging through design, manufacture, preparation and aiming.
Solving the problem of poor torpedo performance and attain-
ing satisfactory results is an "all hands" job. In the
first attack the Commanding Officer estimated the draft to
be fourteen feet. The torpedoes were set to twelve feet,
allowing two feet for error. This is cutting the margin
rather thin, as it is possible that the original draft es-
timate was too deep. Then again, the torpedo performance
may have been influenced by the large change in temperature
between Pearl and the Okhotsk Sea affecting the internal
adjustments.

3.
The Squadron Commander congratulates the
Commanding Officer, officers and crew on the results pro-
duced.
