1. The first patrol of the SAWFISH was extremely successful and
aggressive. The officers and crew carried out their mission like seasoned
veterans.

2. It is noted that the SAWFISH sighted many Russian ships. No
information regarding their positions or routing was available to this force
during the time the SAWFISH was in the area.

3. Excellent use of the radar aided in carrying out attacks and
avoiding small enemy patrol craft. It is gratifying to note that radar
trouble in the SAWFISH was quickly corrected.

4. The Commander Submarine Force, Pacific Fleet, congratulates
the Commanding Officer, officers and men of the SAWFISH for a highly success-
ful patrol during which they inflicted the following damage:

SUNK
1 - Freighter (NAGANO MARU class) - 3,824 tons
1 - Freighter (SINYO MARU class) - 4,300 tons
1 - Passenger Freighter (HARBIN MARU class) - 5,167 tons
TOTAL: 13,291 tons

February 28, 1943
0040(I) Sighted light bearing 000° T in Lat. 30-09 Long. 132-01. Closed
          to 2000 yards and identified as small fishing vessel. Seas too
          rough for gunfire.
0500(I) Submerged and set course 300° T. Decided to patrol Bungo Suido,
          160° line until new moon, then head into coast.

March 1, 1943
0500(I) Sighted patrol boat similar to our 110 ft. PC boats at range 4000
          yards in Lat 30-45 Long 132-15. Kept stern to boat and he did not
          detect us. Sound made first contact.
1852(I) Surfaced and headed southward on special mission.

March 2, 1943
0400(I) Obtained good star fix by moonlight.
0500(I) Submerged and conducted periscope patrol. Seas heavy and had dif-
          ficulty at periscope depth in controlling depth. No contact.
1854(I) Surfaced and set course 335° T, unable to make more than 10 kts into
          sea.

March 3, 1943
0425(I) Sighted light bearing 345° T, estimated distance 15,000 yards and lost
          light in rain squall. Radar did not make contact, believe target to
          be fishing boat.
0451(I) Sighted light bearing 009° T estimated distance 12,000 yards. Light
          was in sight for 5 minutes and then was lost.

          Remained on surface until day was breaking and at 0600(I) submerged -
          nothing in sight.

          Above contacts were in Lat 30-08 Long 133-45.

          No further contacts during day.
1857(I) Surfaced. Gave topside fittings a greasing after surfacing as we had
          trouble with bow buoyancy vent during day. Greasing seemed to clear
          up difficulty.

          Closed coast during night at 5 kts.

March 4, 1943
0500(I) Submerged on course 270° T.
0700(I) Sighted coastal mountains of Kyushu in vicinity of Ariake Wan. Continu-
          ed closing until we crossed 100 fathom curve then turned to 180° T at
          1200(I).
1905(I) Surfaced and patrolled in vicinity of 100 fathom curve off Ariake Wan.

March 5, 1943
0500(I) Submerged and patrolled east and west in area east of Ariake Wan at
          about 100 fathom curve. No contacts.
1900(I) Surfaced and continued patrol at five knots in same vicinity. Radar
          (SJ) does not appear to be working properly. Although we should pick
          up mountains, there is no indication on the scope.

March 6, 1943
0500(I) Submerged and patrolled to east.
1422(I) In Lat 31-17 N, 132-13 E sighted smoke bearing 235° T. Determined
          relative movement of ship and came to normal approach course.

10. MAJOR DEFECTS (Continued):

C. ORDNANCE (Continued:

III. TORPEDO TUBES:
When making the tubes ready for firing the forward
interlock lever on #2 tube was not thrown fully up when the outer
door was opened hydraulically. As the outer door passed the 30°
point the roller chain connecting the interlock shaft and the muz-
zle door operating shaft broke. The interlock shaft was rotated
by hand and the tube made ready for firing.

The taper pins in the muzzle door operating roller
chain spur gears were sheared. The pins were replaced by the ship's
force.

IV. 3"/50 CALIBER GUN:
During the gun action one misfire occurred. The
primer was struck but the cartridge did not fire.

Three rounds were not able to be fully loaded due
either to imperfections of the cartridge case or to wear to the
cartridge case incident to the handling by the ammunition party.

D. COMMUNICATIONS:

I. Upon inspecting electrical leads to the QB pro-
jector head it was noticed that hydraulic oil under pressure found
its way into the annular space between the cylinder and projector
shaft of the assembly, forcing the leads from their stuffing gland
but not rupturing the splice. All this oil could not be syphoned
off. Since these electrical leads to the projector head pass
through the oil flooded annular space, this was probably the cause
for their rapid deterioration. This same condition was reported
by the GUARDFISH on her second patrol.

II. The JK-QC sound head shaft has been found to
be out of alignment. Although not noticeable with the naked eye,
this head on being rotated has a growling and squeaking effect
which can be heard through both receiver amplifiers in the conn-
ing tower and in the forward torpedo room. There are also marks
on the shaft where it appears to be binding.

III It was found that during deep dives the lock-
ing system on the sound heads installed at Portsmouth Navy Yard
was inadequate. The water pressure forced the heads up even though
the locking roller was riding the sound head pelorus. When the
water pressure forced the shafts up, the roller on the locking de-
vice slipped off and training was useless.

11. RADIO RECEPTION (Continued):
RADAR (Continued):
S.J.

1. (Continued). This occurred only when our signal
would catch him broadside.

2-17-43 2. Target was medium sized freighter also sighted by
lookouts first. Radar made contact at 15,000 yards,
Max. range during tracking was 15,800 and min. 4900
yards. Lobe switching was used to a maximum of 13,000
yards.

3. On 2-19-43 what appeared to be a radar sweep was seen
on the equipment.

2-21-43 4. Target was a medium tanker. This target was tracked
for quite some time but at long range only. Radar made
contact at 12,000 yards and max. range obtained was
16,500 yards.

2-22-43 5. Target was a small sampan or patrol boat. Radar
made contact at 3500 yards. Oscillator frequency con-
trol was slightly off, which caused the opening range
to be short.

2-27-43 6. Target was a small patrol vessel. Maximum range ob-
tained was 6000 yards.

3-1-43 7. Target was a small patrol boat picked up first by
sound. Radar coached or obtained range of 3600.

S.D. RADAR:

Enroute from Pearl to Midway, the antenna mast was
flooded and S.D. was inoperative. Midway removed mast and found
cracked insulator. Insulator was renewed and mast flushed.

Upon leaving Midway, plane contacts were made with
5 miles being the maximum distance.

Enroute to area, low flying plane was sighted by
lookout. S.D. failed to pick up this target. This was the only
target for the S.D. enroute to area and while in area although
considerable high mountains were sighted at about 15-20 miles,
S.D. failed to pick these up also.

To   :        The Commander, Submarine Force, Pacific Fleet.
Via  :        The Commander, Submarine Squadron FOUR.

Subject:      U.S.S. SAWFISH - Report of First War Patrol. Period
              from 21 January, 1943 to 25 March, 1943. Areas
              Operating under Comsubpac Operation Order #18-43.

1.            Forwarded.

2.            (a) Attack No. 1.
                  This attack was well executed. Depth settings
                  of six feet are not understood, however, clari-
                  fication in the minds of all hands of torpedo
                  performance to be expected is indicated.

              (b) Attack No. 2.
                  An excellent approach and attack.

              (c) Attacks No. 3 and No. 4.
                  The enemy won this round. SAWFISH definitely
                  held the second best hand. The commanding
                  officer's post mortem is fully concurred in
                  by his kibitzer.

              (d) Attack No. 5.
                  Very excellent tactics were employed before,
                  during and after the attack.

              (e) Gun Action.
                  The Commanding Officer's well known aggressive
                  character is amply borne out by this action.

3.            The report of the first war patrol of SAWFISH gives
the reader the impression that he is reading the report of a well-
seasoned submarine. All facilities were used in a most intelligent
manner. Every opportunity that presented itself to inflict damage
on the enemy was eagerly grasped.

4.            The Division Commander congratulates the Commanding
Officer, Officers and crew on the damage inflicted on the enemy
and upon the excellent manner in which the patrol was conducted.

1. The second war patrol of the U.S.S. SAWFISH was carried out in
an area that is normally well above average in the number of contacts made per
day of all our operating areas. It is unfortunate that the SAWFISH made but
four contacts suitable for attacking. Much of this was due to increased enemy
anti-submarine warfare activity.

2. Of the four contacts made, two attacks were carried out, one
of which was successful. This attack was well executed. The chase of the
large Japanese Task Force was aggressive, and with the information available
to the Commanding Officer as the chase developed, it is felt that every step
possible was taken to close the enemy for an attack. It is unfortunate that
heavy seas and the speed of the enemy Task Force kept the SAWFISH from getting
in.

3. It appears that the SAWFISH made good use of the bathythermo-
graph. Constant use of this instrument during patrol and careful analysis
of the results which it gives is encouraged in order that all submarines may
become more expert in the use of density layers for evasive tactics when sub-
jected to depth charging.

4. The Commander Submarine Force, Pacific Fleet, congratulates the
Commanding Officer, officers, and crew for this patrol, during which the fol-
lowing damage was inflicted to the enemy:

The escort was joined in depth charging by two smaller craft which
dropped a total of seven charges. The escort dropped ten.

9. MINESWEEPING OPERATIONS

What appeared to be minesweeping operations was noticed on May 5, 1943.
Two vessels about 150 feet long were working the shoals the center of which is
17 miles bearing 169° T from OMAI ZAKI. They were first on course about 250°T,
about 1,000 yards abeam of each other. They reversed this course about an
hour after sighting and disappeared, on course 070° T.

Due to the currents encountered in this area and the resulting poor
DR positions, it appears feasible that sweeping operations on this shoal may
be expected when ships are expected from the south.

10. MAJOR DEFECTS.

A. HULL
(1) The automatic by-pass valve in the main hydraulic system has,
on several occasions, stuck in the partially closed position. The faulty
operation of the by-pass valve is believed to be due to the binding of the
leather cup washer under pressure. An unsuccessful attempt was made to fit
a new leather cup washer. The original washer was dressed down and rein-
stalled. The operation of the automatic by-pass valve was improved but is not
fully satisfactory. Having the hydraulic plant out of commission for only the
fifteen minutes required for the above remedy constitutes a military hazard,
particularly if ship is on the surface.
(2) Bow buoyancy vent valve occasionally sticks in the OPEN posi-
tion when the valve operation is by hydraulic power. This failure of the vent
valve is believed to be due to oil leaking in the hydraulic manifold. The
valve operating lever in the control room must be momentarily placed in the
HAND position when moving from the OPEN to the CLOSED position.
(3) No. 2 periscope was consistently unsatisfactory after the
second week of patrol. The same condition existed on the first patrol. Diffi-
culty was experienced maintaining the internal pressure and fogging developed.
All nitrogen used was passed through a silica-jell dehydrator. The No. 1
periscope was finally moved into the conning tower and was very satisfactory.
It is recommended that #2 periscope be overhauled in the shop.

B. ENGINEERING
(1) On two separate occasions threads stripped on indicator cock
sleeves on the Auxiliary Engine. Once on #3 cylinder and again on #6 cylinder.
These sleeves are made of bronze composition metal which is believed to be too
soft a material for this purpose. It is noted that the on-board spares which
were used as replacements are made of steel and should do the job much better.
(2) Lube oil guage line on #1 M.E. developed a leak due to a hole
being rubbed in the line by vibration at a point where the line touched the
engine. Patched by ship's force.

It seems that NPM does not realize that length of transmission is very
important to the S/M.

Delay in clearing the message on 20 May was encountered when NPM, NPG, and
NPR all answered up to our original call. It is suggested that NPM be the con-
trol station when such occurs to prevent confusion.
Last consecutive serial number received: 14.

12. SOUND CONDITIONS AND DENSITY LAYERS.

    Sound conditions were generally good throughout all areas covered in patrol.
    The presence of large numbers of fish in area however, sometimes confused
    the sound operators.
    Listening conditions were excellent during evasion after the attack, which
    condition worked better for the enemy than for us. We could hear the escort's en-
    gines or auxiliary machinery running even when his propellers were stopped, during
    some phases of the evasion. After the escort left, we had to speed up to maintain
    depth and were successful in eluding the two small craft at speeds up to 70 RPM.
    When we increased to 90 RPM, however, they were right on us.
    Density layers were encountered in areas and but not daily. When encount-
    ered, a heavy layer about 50 feet deep was found with upper level at 90-125 feet.
    An extremely heavy layer was encountered at 300 feet on day of attack. Flooding
    to get through this made us about 4000 lbs heavy at 350 feet.
    In vicinity of MURATO ZAKI we once struck a light density pocket at periscope
    depth and went to 100 feet before control was gained with 2/3 speed.

13. HEALTH AND HABITABILITY.

    Health and habitability was generally good. A number of men were inflicted
    with slight colds during the early part of the patrol. Vitamin tablets were ex-
    tensively used after this; the colds disappeared but headaches developed and may
    be caused by the pills.

1. Forwarded.

2. The attack on the naval auxiliary on May 5 was very well conducted
and it is regretted that positive evidence of his destruction was not obtained.
The tactics employed in all phases of this attack and the evasion tactics employed
after the attack are considered excellent. Very slight damage was suffered by
SAWFISH. Two depth charges went off directly over the ship set at about two hun-
dred feet.

3. The keen disappointment of the Commanding Officer in his inability
to deliver an attack on the enemy task force contacted May 20 is shared by the
Division Commander.

4. Refit will be accomplished by the Base in the normal time. Docking
is required. The material condition of the ship is considered good. Number two
periscope will be replaced by a spare and the periscope removed given a thorough
overhaul.

5. Morale in the ship is excellent.

6. The Division Commander takes pleasure in congratulating the Command-
ing Officer, Officers and crew of SAWFISH on the damage inflicted on the enemy.

Subject:      U.S.S. SAWFISH, Report of War Patrol Number Three.

1.            Forwarded.

2.            The third war patrol of SAWFISH was courageously
conducted with intelligence, skill, determination and aggressiveness.

3.            ATTACKS:

              The first three attacks at night, on a strongly escorted
convoy were well and successfully done. Three ships in the
convoy were hit and SAWFISH evaded any serious counter attacks
by remaining at periscope depth and observing the escorts.
Attempted daylight pursuit of the convoy was frustrated by
enemy planes.

              The fourth attack was a masterpiece. In the afternoon,
SAWFISH held her fire when conditions turned out to be un-
favorable and waited for darkness. The zig plan of the enemy
was studied. The hits made on an extremely valuable target at
high range were not fluke hits - they were the result of
careful and clever planning and execution.

              The fifth attack was unsuccessful. The high speed and
radical zigs of the target prevented attainment of a favorable
firing position.

              On the sixth attack SAWFISH sank a DD with the "Down
the Throat" technique.

4.            MATERIAL:

              The material condition that gives the most concern
is alignment of main shafts. This will be thoroughly in-
vestigated and may develop into a reboring job.

1. The third war patrol of the SAWFISH was aggressive and successful.
Taking advantage of an area dense with valuable contacts, the SAWFISH completed
her mission in one week, making six attacks, of which four resulted in severe
damage to the enemy.

2. All attacks except one were night attacks and showed clever use
of the radar. Particularly tenacious was the attack on the convoy which con-
tained a large troop-laden vessel of the ASAMA MARU class. The SAWFISH con-
tacted this convoy in daytime and after several unsuccessful efforts were made
to obtain a favorable position on the most important target, the Commanding
Officer decided to let the convoy go on and make a night attack. This proved
to be a correct estimate of the situation. The SAWFISH chased the convoy and
was unable to close for a close range shot because of moonlight. A careful
check of the zig plan used was made and the SAWFISH then fired six torpedoes at
a range of 6,700 yards, obtaining three hits and sinking a 17,000 ton troop-laden
transport. Another excellent attack performance was the "down the throat" shot
that sank an enemy destroyer.

3. This patrol is considered successful for Combat Insignia award.

4. The Commander Submarine Force, Pacific Fleet, congratulates the
Commanding Officer, officers, and crew for an excellent, aggressive patrol.
The SAWFISH is credited with having inflicted the following damage to the enemy:

REMARKS:
On the first attack, torpedo number 53398, fired from no.
2 tube, as the second of a two torpedo salvo, was heard to hit
the shutter or hull plating when ejected. This torpedo did not
run. The other torpedo passed astern. On the second attack,
torpedo no.53388, fired from no.1 tube, as the first of a 3 tor-
pedo salvo, was heard to hit the shutter or hull plating when
ejected. This torpedo did not run. The other torpedoes of this
salvo appeared to miss astern. Tracked out on sound.
Immediately after this approach, the operation and action
of no.1 torpedo tube were thoroughly checked. There appeared to
be no misalignment of any part of the operating mechanism. The
outer door opened and closed smoothly. The checked firing
bearings were worked against the MK8 angle solver; no appreciable
error. The TDC and periscopes were likewise checked, the TDC
being well within the allowable errors and the periscopes lineup.
After the second approach and attack, all remaining MK18
torpedoes were thoroughly checked by the ship's electrical depart-
ment personnel, especially the following: proper operation of
starting switch; took resistance readings on the armature cir-
cuits; checked the continuity of the motor hook-up; checked ground
readings; examined wiring and batteries. Electrical conditions of
remaining torpedoes were considered satisfactory.
(Note: In both these attacks, even though torpedoes had
passed either ahead or astern of the target, HE MADE NO INDIC-
TION AT ALL OF BEING AWARE THAT HE HAD BEEN ATTACKED.)

(L) RADIO:
     1. Last serial received: 63:

     2. Reception during this patrol was normal; 12,345
Kcs and 8230 Kcs were excellent and 4115 was fair with some
interference from the Japs. 4235 Kcs was also guarded between
S/M Fox schedules for special communication with WAHCO. No
traffic was sent or received on this circuit while in area.

     3. The first message sent on 4235 Kcs the night after
clearing the KURIL ISLAND Chain. On the first call NZL - ATTU
Island answered and asked for our message. No other station
was heard so message was cleared through NZL in 12 minutes with
no difficulty.

(M) RADAR:
     1. SD Radar: The performance of the SD radar during
this patrol was questionable. We obtained long ranges on
mountain peaks while the two enemy planes encountered on the
surface were not detected. Both of these planes were approx-
imately 1000 feet in altitude and from 8-10 miles in range.
Both were medium size planes.
          There were no casualties encountered except for
routine replacement of tubes.

     2. SJ Radar: Except for the range unit the perfor-
mance of the SJ equipment was very good.
          The difficulty encountered with the range unit was
due to the lack of spare parts for the crystal tank. If spare
crystals, crystal loads and pulleys, which are tender spares,
were on board the range unit could have been kept in operation.
          Ranges were obtained on targets with an improvised
range scale which was taped to the screen.
          Enroute Pearl to Midway the SJ motor-generator devel-
oped a bad bearing. Considerable time was saved by replacing
the motor-generator with one received from U.S.S. SPERRY
instead of repairing the defective unit on board.

(N) SOUND:
     1. Sound results were average throughout patrol.
Maximum range on props was 10,000 yards. On two attacks a
single ping range was taken and results were excellent.

Fleet.

Subject: U.S.S. SAWFISH - Report of War Patrol Number Four.

1. SAWFISH fourth war patrol conducted in Sea of
Japan extended over a period of 37 days, 18 days of which were
spent in patrol area. Patrol was terminated by decision to
carry remaining torpedoes to base for examination as result of
faulty torpedo performance.

2. During this patrol 14 contacts were made with
18 ships, one of which was about 5000 tons and the remainder
from 1000 to 2500 tons. All ships were unescorted except one
convoy of 4 freighters and another of 2 freighters. Seven
attacks were made, three being conducted against one freighter.
No damage was done to the enemy.

3. Although SAWFISH has made a separate report of
torpedo performance, a resume of the firing results follows.
1 Mk. 18 torpedoes hit the bow in vicinity of the shutter
(tube numbers 1, 2, and 5) and were not heard to run there-
after. 1 Mk. 18 was heard to hit something after a 30 second
run. SAWFISH believes it hit bottom in 68 fathoms of water.
7 Mk. 18's were heard by sound and tracked running astern of
target. The first torpedo of a 3, Mk. 14, torpedo spread
broached, ran erratically and target maneuvered to avoid the
remainder. On another spread of 3, Mk. 14, torpedoes, 2 were
heard by two sound operators to hit the enemy but failed to
explode and the third missed astern. All attacks were care-
fully planned, data checked and attacks made from favorable
positions by a skilled Commanding Officer and by a previously
proven well trained fire control party.

4. Despite the discouraging performance of the
torpedoes, SAWFISH morale is impressively of the highest order.
The material condition of the ship shows keen attention to up-
keep of material during the patrol. A short refit period will
be given and SAWFISH will depart on patrol within 2 weeks.

         War Patrol.

1. The Fourth War Patrol of the SAWFISH is one of
the first in which the Mark XVIII torpedoes were extensively
employed. The results were disappointing, and indications
are that considerable testing and proof firing will be nece-
ssary before the Mark XVIII is satisfactory for service use.

2. It is noted that most of the enemy vessels en-
countered in the area were of small or medium tonnage. Anti-
submarine activity is still defensive in character and patrol
vessels are not numerous.

3. It is recommended that no damage to the enemy
be credited to the SAWFISH.

Subject: U.S.S. SAWFISH (SS276) - Report of Fourth War Patrol.
(10 September to 16 October 1943).

1. The fourth war patrol of the SAWFISH was conducted in the Japan
Sea.

2. The SAWFISH conducted excellent area coverage and had many con-
tacts. The SAWFISH made seven attacks, using both electric and Mark 14 tor-
pedoes. A combination of duds, erratic torpedoes caused by torpedoes striking
the tube shutters and excessive ranges, resulted in no damage to the enemy.

3. It is noted that the SAWFISH obtained excellent range results
using the single ping method on the QC gear.

4. Two Russian ships were sighted and these were properly marked
in accordance with the new instructions. It is of note that the Japanese evi-
dentially use excellent sound devices in Tsugaru Straits for picking up high
speed targets.

5. This patrol is not considered successful for Combat Insignia
Award.

AK's and two escorts. Being unable to close the target, the command-
ing officer fired five torpedoes at a range of 6300 yards making
three hits on an AK or AKs causing damage.
The second attack was on an AK with an escort. Four
torpedoes were fired making two hits. Several minutes after the
second hit, there was a terrific explosion. The target sank.

3. The morale and health of the crew on arrival were
excellent.

4. The SAWFISH is on her way to Navy Yard, Mare Island
for overhaul. Only voyage repairs are necessary at this time.

5. The Commanding Officer, officers, and men are to be
congratulated on inflicting the following damage on the enemy:

1 AK (Sunk) - 6,000 tons

FIRST ENDORSEMENT to
U.S.S. SAWFISH Report
of Sixth War Patrol.

From:      Commander Submarine Division One Hundred Forty One.
To :       Commander Submarine Force, Pacific Fleet.
Via :      Commander Submarine Squadron Fourteen.

Subject:   U.S.S. SAWFISH (SS276) - Report of Sixth War Patrol;
           Comments on.

           1. The sixth war patrol of the SAWFISH was the first for the
new commanding officer as such. The patrol was conducted in Empire areas
and lasted for a period of fifty-one days of which thirty-one days were
spent in assigned areas. Good area coverage was maintained but there were
only two contacts with torpedo targets and one of these could not be closed
to firing position. While patrolling submerged in reduced visibility,
sight contact was made on one ship which later developed into two AKs with
two escorts. Good firing position was attained on the near AK identified
as similar to the TOYOKAWA MARU. At range 1600 yards four torpedoes were
fired from bow tubes on 105° track, spread to cover 130 percent of target
length. Two hits were observed, one under the stack and one in the bow.
The target broke in two and sank in less than two minutes. Excessive
range and poor visibility prevented an attack on the second AK before be-
ing forced down by the escort.

           2. MATERIAL.
           The SAWFISH returned from patrol in fair material condi-
tion. This is the first patrol following a navy yard overhaul and many
defects developed which require correction. It is expected that all unsatis-
factory items listed in sub-paragraph (K) will be rectified during current
refit. BUSHNELL will accomplish the refit in the normal period.

           3. The Commanding Officer, officers and crew are congratulated
for inflicting the following damage upon the enemy:

                                 SUNK

1 - AK (identified as similar to TOYOKAWA MARU)           - 5,124 tons

Subject: U.S.S. SATFISH Seventh War Patrol - comments on.

1. The seventh war patrol for the U.S.S. SATFISH was the second
war patrol for Commander BANISTER as Commanding Officer. This patrol covers a
period of forty-six days of which thirty were spent in the area. This ship was
one of a pack consisting of the ROCK, TILEFISH, and SATFISH under the Command
of Captain Warren D. WILKINS.

2. All ship contacts worthy of developing were attack.

(a) Attack No. 1 and 2. Six (6) torpedoes were fired from the bow
tubes at a large tanker making two hits. Six minutes later four torpedoes were
fired from the stern tubes. No hits are claimed under attack number two. The
tanker was down by the bow when it was last sighted.

(b) Attack No. 3. Four torpedoes were fired at an I-5 class
Japanese submarine. Three hits were made which sank the Jap submarine.

(c) Attack No. 4. Four torpedoes were fired at a target at night by
SJ Radar and TBT bearing. No hits were made. It is believed that the torpedoes
passed under the target.

Anti-submarine measures were very aggressive and active.

3. The health and morale of the crew on arrival was excellent.
Defects noted in report will be remedied and corrected during the present refit
at the Submarine Base.

4. The commanding officer, officers, and men are to be congratulated
on their excellent patrol and damage inflicted to enemy submarines and
shipping.
