The first Sand Lance, a submarine, was laid down on
12 March 1943 by the Portsmouth (N.H.) Naval Ship-
yard; launched on 25 June 1943; sponsored by Mrs.
Edith Burrows; and commissioned on 9 October 1943
at Portsmouth, N.H., Comdr. Malcolm E. Garrison in
command.

Sand Lance conducted training exercises out of New
London, Conn., until 18 December 1943 when she sailed
for the Panama Canal. She transited the canal on 30
December and reached her base of operations, Pearl
Harbor, Hawaii, on 17 January 1944. On 8 February
she got underway for the first of her five war patrols.
She stopped at Midway Island for fuel, then headed
for the Kuril Islands.

Before entering her patrol area off Paramushiro on
24 February, she passed through two typhoons and
encountered fields of slush ice and patches of drift ice.
Sand Lance encountered her first victim, Kaika Maru,
taking shelter from a blizzard in the lee of Paramu-
shiro's southeast point. Her well-aimed torpedoes sent
that enemy ship to the bottom. Though her number one
periscope had been heavily damaged by drift ice, she
pressed home attacks on a convoy on the night of 2
and 3 March, sinking the 4,521-ton cargo ship, Aka-
tsan Maru, and damaging other ships.

On the night of 12 and 13 March, Sand Lance was
running on the surface toward Honshu when a mer-
rauding airplane forced her to submerge. At about 0200
she came up to periscope depth and found herself in
the midst of a Japanese convoy, consisting of five
merchantmen and three heavily-armed warships. Sand
Lance had only six torpedoes remaining, but she made
them count. She loosed four from the stern tubes and
two from the bow tubes. All six hit the mark. Two of
the four stern torpedoes hit a merchantman and the
other two ripped into a light cruiser, while the two
from the bow tubes smashed into another freighter. At
least two of the ships went to the bottom, light cruiser
Tatsuta, and cargoman, Kokuyo Maru. For her suc-
cess, Sand Lance underwent a 16-hour, 100-deep-
charge pounding from the accompanying destroyers.
Finally, she was able to head home. She arrived at
Pearl Harbor on 23 April 1944. The successes of her
maiden war patrol brought Sand Lance a Presidential
Unit Citation.

Sand Lance spent her second war patrol in the
vicinity of the Marianas Islands and terminated it on
the eve of the American invasion of those islands. She
contributed to the success of that campaign by dep-
ing the defending Japanese of the war material carried
by five ships. On 3 May 1944, just north of Saipan,
she torpedoed and sank the 3,129-ton cargo ship,
Kenan Maru. Eight days later, she damaged Mitake
Maru, a 4,411-ton passenger-cargo ship, while evading
the bombs from an attacking enemy plane. Sand Lance
sent the 4,291-ton freighter, Koho Maru, to the bottom
on 14 May off Apra Harbor, Guam, and found two
more targets off Saipan on the 17th. This last attack saw
the sinking of Taioku Maru and Fukko Maru. Having
hausted her supply of torpedoes, she headed south
to Fremantle, Australia, arriving on 5 June 1944.

The submarine put to sea on 3 July 1944 to patrol the
Molucca and Celebes seas. She sank the converted
gunboat, Taiko Maru, on 14 July and damaged another
ship in the same attack. Four days later, she received
a good shaking from fast patrol craft while trying to
press an attack on a large transport in the Sulu
Islands. Sand Lance did not find another target until 1
August when she damaged a freighter south of Lom-
bok Island. Two days later, she barely escaped the
bombs of a plane which almost caught her in the
shallow waters of Amoesang Bay. She sped back
through the entrance to the bay and the safety of
deeper water.

More bombs exploded astern on the morning of 4
August as she stalked some small freighters along the
coast of Celebes. The force of the explosion lifted her
several feet and damaged her port shaft.
Soon, the submarine had two additional problems: en-
emy escorts bearing down on her and a torpedo run-
ning hot in one of her stern tubes. Sand Lance came
up to 100 feet and fired the torpedo. Eight seconds
later, it exploded prematurely, adding to the damage to
her stern. Fortunately, the explosion apparently con-
vinced the Japanese that they had destroyed the sub-
marine, for Sand Lance received no further attacks.
She surfaced after dark, but the damaged gear could
not be repaired. Forced to make the voyage back to
Fremantle on one shaft, she made port on 19 August.
On 10 September, she headed east for Pearl Harbor
and, from there, on to Mare Island Naval Shipyard,
where she arrived on 1 November.

Repairs were completed by 13 March 1945 when she
sailed back to Pearl Harbor. On her fourth war patrol,
from 10 April to 6 June 1945, Sand Lance encountered
only one target, an unidentified coastal freighter which
she torpedoed on 14 May. She departed from her patrol
area, along the coasts of Honshu and Hokkaido, and
returned to Midway on 6 June. One month later, she
sailed from Midway on her fifth and last war patrol.
She fueled at Saipan, then took up lifeguard station
for the bombers raiding the Japanese home islands.
Hostilities ceased on 15 August; and, on the next day,
Sand Lance made for San Francisco, via Midway and
Pearl Harbor. She entered the San Francisco Naval
Shipyard at Hunter's Point on 7 September for inacti-
vation overhaul. Sand Lance decommissioned at San
Francisco on 14 February 1946.

Sand Lance remained inactive until designated for
loan to the Brazilian Navy under the terms of the
Military Assistance Program. After reconditioning, she
recommissioned at Pearl Harbor on 6 April 1959,
Comdr. Carl H. Sebenius, Jr., in command. She de-
parted Pearl Harbor on 24 June and made San Fran-
cisco on 1 July to embark officers and men of the
Brazilian Navy for training. The training was com-
pleted by 7 September 1963 when she was decommis-
sioned and turned over to Brazil. She served that navy
as Rio Grande do Sol (S-11) until 1 September 1972.
At that time, she was sold to the government of Brazil
for $55,000, and her name was struck from the Navy
list.

Sand Lance (SS-381) earned five battle stars and a
Presidential Unit Citation for World War II service.

(A) PROLOGUE

17 Jan. Arrived Pearl Harbor from Panama.

18 Jan. -
7 Feb. Voyage repairs, fourteen days training, sound tested, depermed,
        two days loading.

8 Feb. Ready for sea.

(B) NARRATIVE

8 Feb.
1300 Underway from Pearl Harbor in company with Trout and Rock, one FC
        as escort.
1330 Escort departed. All three ships proceeded independently.

13 Feb.
1300 Arrived Midway. Weather too rough to enter. Cruised southeast
        of island waiting for weather to moderate.

14 Feb.
1100 Entered Midway.

15 Feb.
0800 Departed Midway, having fueled and repaired hull ventilation
        supply blower.

18 Feb. Ran through the center of a typhoon. Wind changed 160° in less
        than five minutes. Wind force 12, mountainous seas. Sea coming
        in the engine induction faster than drain pump can handle it.
        To avoid flooding the generators were required to cruise most of
        the day in a large circle at five knots, always heading into the
        sea as it shifted. We have lost a full day due to weather.

20 Feb. Submerged for four hours to water batteries, service torpedoes
        and clear a few full voltage grounds.

21 Feb. A duplicate performance. Right through the center again. Barely
        making steerage way to keep from being swamped and already two
        days behind schedule. The ship rolled so violently the gyro hit
        the stops and precessed one hundred degrees. Two typhoons in
        four days is overdoing it.

23 Feb. Submerged for six hours to work on #4 engine, the fathometer and
        the master gyro. Have been steering by the auxiliary gyro for
        several days as the master is unreliable. It is so rough and wet
        when on the surface it requires full concentration just to stand
        up so any repair work must be done submerged.

24 Feb.     Combination of ice on antennas and heavy seas finally tied up
            the after antenna mast like a pretzel and carried away all anten-
            nas. The whole topside, including the CUD and lookouts, is
            covered by about six inches of ice.
1600(K)     Finally arrived off Paramushiru three days later than expected.
            Have averaged turns for 13 knots and have averaged 9.5 knots over
            the ground since leaving Midway. Encountered a solid mass of
            drift ice eighteen miles from the island. It is a weird sensa-
            tion to be completely surrounded as far as you can see by a solid
            sheet of ice. After dark found shelter in the lee of the island
            and had a minor refit. Cleared the bow buoyancy vent operating
            rods which were fouled by the sea caving the deck in forward,
            cleared several stanchions and deck lockers which were partially
            torn away, and strung a jury-rig antenna.

25 Feb.     Patrolling in Higashi Banjo Suido. We are under a large area of
            drift ice which I thought might damage the periscope but it hasn't
            so far.

26 Feb.     Patrolling in Higashi Banjo Suido. A storm came up and blew
            away the ice, but it is snowing so hard we are patrolling on
            the surface using the radar.

27 Feb.     Patrolling off Musashi Wan. A new problem has arisen. It has
            turned colder and the instant the periscope is exposed a film of
            ice freezes over it. It is a clear day for a change and we are
            four miles from an air field so must stay submerged. I don't
            have much faith in sound but there isn't much choice. I am
            finding that there is a good deal about real cold weather opera-
            tion I don't know about.
1000(K)     Less than four minutes after a 25 fathom sounding ran aground
            while at 90 feet. Blew up a little and pulled clear with no
            apparent damage.

28 Feb.     Patrolling off Musashi Wan.
1435(K)     Sighted masts and stack of ship and immediately lost it again
            in heavy snowstorm.
1500(K)     Located ship again and went to battle stations. Single stack AK
            similar to HAMBURG MARU with one escort. Approach was very con-
            fusing until eventually I discovered the ship was anchored and
            was bucking a two knot current at three knots. At
1629(K)     just prior to firing went aground at 60 feet. Planed up to 50
            feet and fired three torpedoes. All hit and ship capsized and
            sank in two minutes. Swung to clear escort and hit bottom again.
            Escort appeared confused and dropped ten charges at random, none close.
            in less than 60 feet of water. Upon taking stock of situation, discovered
            JK head is missing and Bendix log sword arm is bent but operative.

2 March Patrolling in Yetorofu Jima. While making a submerged observa-
        tion, #1 periscope struck a large piece of drift ice and was
        bent. It cannot be lowered or used and is a definite hazard
        during a submerged approach. Lost our jury rig antenna. I guess
        we'll have to be content with the SD mast and the loop.
2300(K) Radar contact at 14000 yards. Contact developed into two ships
        plus escort, leading ship the larger. Made approach from down
        moon at radar depth but as escort was on the quarter on that side
        it meant firing from directly ahead of him. Fired three at leading
        ship, three hits; fired three at second ship, one hit. The leading
        ship went up in a tremendous burst of flame several hundred feet
        high and disappeared instantaneously. He must have been loaded
        with aviation gas. Escort headed directly for us at 1400 yards.
        We and SAND LANCE were equally impeded by heavy field of drift ice
        two feet thick. Went to 400 feet - eight depth charges, some close
        but no damage. After two hours surfaced and commenced search for
        damaged ship and at
3 March made radar contact. Commenced end around but just as we gained
0315(K) position ahead the target stopped. As the moon had now set and
        the radar does not give much indication of track on a stopped
        target, decided to wait for day light due in one hour. At
0615(K) commenced submerged approach. When we got close it developed
        the escort was still apparently searching at the location of the
        first attack so maneuvered for a stern tube shot. Fired three
        torpedoes. First one purposed about 100 yards from ship and
        then ran erratic so fired one more. Three hits. Target sank in
        twenty minutes. When Mk 18's are at 35° temperature their speed
        is so reduced that the wait for them to hit is interminable.
        This second ship was positively identified as the FLORIDA MARU.
        Since the first one was a modern single stack four goal post
        freighter at least fifty feet longer than this ship, I averaged
        this type and length in 208-J and arrived at 8500 tons. Its gen-
        eral outline was similar to that of GOYA MARU.
        Patrolling along Kuriles enroute Area 5. Spent the whole day
        trying to remove the upper bearing from #1 periscope to permit
        lowering it about 5 feet.

4 March Still working on #1 periscope without
        much success. Heavy seas and snowing hard.

5 March While off the coast of Hokkaido at
1000(I) dove on SD contact at four miles. Shortly after passing 200
        feet one bomb exploded. One hour later another bomb and fifteen
        minutes later a third. I have been quite sure for the past five
        days that we were leaving an oil slick either from the groundings
        or depth charges. Now that we are in areas of heavy air coverage
        it will prove very embarrassing. Two hours later two more bombs.
        They sound very heavy but set shallow. Some high speed screws
        have joined that party.

1430(I) Surfaced - all clear.

8 March It has been snowing for three days so our position is doubtful
          to say the least. Every time we work in to the coast we run into
          heavy fields of ice. As we are off Tsugaru Strait or Northern
          Honshu, I can't afford to be driven down in the ice by planes and
          wreck my one remaining periscope. Within ten miles of the coast
          the ice is heavy as far south as 41° latitude.

11 March Patrolling enroute Area five off Inubo Saki, at
          1400(I) sighted a small freighter. Closed at full speed submerged for
          45 minutes and had just gained an attack position when target
          zigged 60 degrees. Swung to a 70 track and looked again and
          target had swung around to present stern to us. Fired two snap
          shots, both missed. Started to swing to chase when a bomb ex-
          ploded, fairly close so went to 250 feet. Target had undoubtedly
          sighted our periscopes on last observation as range was 1700
          yards. This business of having #1 periscope jammed in the fully
          raised position and still unusable makes a periscope depth ap-
          proach almost impossible in a rough sea. After an hour and a half
          came to periscope depth and immediately picked up two more small
          freighters. This time made a very cautious approach and fired
          three torpedoes at the second one at a range of 2000 yards, 110
          track and zero gyro with a 2° divergent spread. No hits so came
          up for a good look and was surprised that they were identical to
          previous contact. They were 1500-1800 ton coastal freighters
          with large lookout platforms and arms and guns forward and aft and lightly
          loaded. They were now steering aimlessly around the area and it
          finally dawned on me they were probably decoys drawing about six
          feet of water and I had been suckered into wasting five good tor-
          pedoes. Immediately started down and was urged along by a bomb
          or depth charge, fairly close, probably a bomb as no other ships
          were in sight. This alone should have made me suspicious as
          everything at least has a trawler escort. Went to 300 feet and
          withdrew from that vicinity. We had sighted a small patrol boat
          last night and evaded on the surface but perhaps we were seen and
          reported.
          1900(I) Surfaced - all clear.
          2230(I) In the light of a full moon lookout sighted a 2 engine bomber
          coming in fast so dove to 200 feet.
          2330(I) Surfaced - all clear. We are now in the Japan current and the
          water temperature has risen 35 degrees. Two more SD contacts
          but did not come closer than four miles so did not dive.

13 March
          0130(I) SD contact closing to four miles so dove. At
          0215(I) came up to radar depth but as soon as shears broke, the surface
          the plane apparently picked them up and closed fast. This ter-
          ritory is certainly well patrolled by planes at night and some
          would seem to have radar. At

13 March (Cont.)
0240(I) sound man reported two ships pinging. This plus the heavy air
activity presented interesting possibilities so came to periscope
depth. There was a sight beautiful to behold. It was worth the
past four weeks of battling typhoons, blizzards and ice fields.
We were completely surrounded by ships. I could see a destroyer,
a light cruiser of the TENRYU class and five AK's all close and
others further away. There was a full moon so the visibility
was excellent. My first thing I did was mentally kick myself
all over the conning tower for expending those five fish two
days before and then set about seeing what could be accomplished
with the six remaining. At
0310(I) fired the four stern tubes - two at the cruiser and two at an
AK which were about two thousand yards away. One hit on the
cruiser and two on the AK. I then swung and fired the two bow
tubes at another AK range about one thousand yards, both hit.
As we were surrounded by ships the escorts couldn't seem to
locate us so, although all torpedoes were expended, I had about
fifteen minutes to watch the developments. The cruiser was
giving off clouds of white smoke but the extent of damage could
not be determined. The AK (MOMOYAMA MARU type), hit by the bow
tubes, sank rapidly by the bow. The AK (same type as first),
hit by the Mk 18's, was enveloped in a cloud of black smoke and
was sinking bodily with decks almost awash when last seen.
Another AK further away seemed damaged and down by the stern so
it could have been single hits in two ships but the closer one
seemed to be sinking too fast to have only one hit so I cannot
legitimately claim another damaged ship. About this time the
situation cleared a little and the sound man reported two des-
troyers coming in fast. I only saw one. We started down amid
a hail of depth charges. The depth charge attack was on in
range and deflection but they seemed to be set for 250 feet
and at 550 feet. We must have done con-
siderable damage from the persistence and severity of the at-
tacks that followed. We were kept down for eighteen and a half
hours and depth charged for sixteen of the. In all 105 charges
were dropped which, until someone tells a better story, I claim
is pretty near a record number of charges dropped in a single
sustained attack. At
1900(I) we surfaced with a radar contact six thousand yards on the
starboard bow. There was an island on the port bow and we were
being forced in that direction. I always thought there was a
reason for our having 2000 H.P. engines so we turned them on
full which gave a 150% overload to the generators but we simply
ran away from him. Our Bendix log was damaged off Paramushiru
so I don't know what speed we made but we left that Jap flat-
footed.

13 March (Cont.)
          The course and speed of the convoy would put them in the
          BATFISH's area at midnight so we sent the contact report
          three times on 450 kcs but naturally did not get a reply.
          Departed area and set course for Midway. We had just
          cleared our Japanese friend when everything stopped and
          there came the terrifying alarm "Fire in the Maneuvering
          Room". I lost five years of my life in five seconds but
          it developed there was a short among some meter leads and
          we got underway again immediately.

(C) WEATHER

Generally speaking, the weather during this run was consistently
bad. On February 12, while enroute Midway, we ran through a heavy
gale. Heavy weather then continued after our arrival at Midway and
prevented us from entering the channel forcing us to conduct a sur-
face patrol in Area 26 for 48 hours.
On February 18 and 19 we were in a low pressure area which slowed
us down to 5 knots while making turns for 13. On February 18 we were
in the middle of a cyclone, a rather uncomfortable place to be, to say
the least. Wind force - 12, sea condition - 10.
On February 21, after about 8 hours respite from the last one,
we found ourselves in the center of another cyclone. Barometer - 28.82,
wind force - 11 and variable through 270°. Heavy swells with top cross
shop made for mountainous seas. Rolling 45 - 50 degrees. Rather un-
comfortable. February 22, the storm moderated some but it started to
snow. February 23 - first star since 18th. 3 stars of doubtful quality.
Rain, snow, rough, cold (28°F).
February 24 - made landfall on Paramushiru in reduced visibility.
Seas had flattened due only to the fact that they were covered with a
thin sheet of ice. During the entire period we were in the Kurile
area we encountered drift ice close to land both in the Okhotsh Sea
and in the Pacific. Average temperature was 29°F with snow flurries
at regular intervals which decreased the visibility to 100 yards. The
sea was fairly calm on only three of the 8 days spent in this area.
Wind averaged force 5 and was generally, from N.W. While in Etorofu
Kaikyo encountered chunks of drift ice that were from 5 to 6 feet
thick. From March 4 to March 11 while proceeding from Kuriles down
coast of Hokkaido and Honshu the sky was 100% overcast and in spite
of a fairly high barometer, 29.9 - 30.1, the sea was rough and the
wind force 4 - 5.
On March 11, ran into the Japanese Current off Inubo Saki and
also into fair and warmer weather.
The weather in the vicinity of Nanpo Shota was fairly pleasant.
Heavy fields of drift ice several feet thick were encountered
off Hokkaido as far south as Tsugaru Strait.

(D) TIDAL INFORMATION

Tides and currents agreed with the information contained in the
Coast Pilot, the Pilot Chart and the effective ICPOA. Strong sets
were experienced when close to land in the Kurile Island area and
generally speaking, were N.W. on the flood and S.E. on the ebb. Drift
varied from 1 - 3 knots. Strongest current was in Onekotan Kaikyo off
Mushashi Wan where a current of 3½ knots setting 305 was encountered.
In this same area there was no easterly set at all on February 27.

(E) NAVIGATIONAL AIDS

None observed.

Target Data - Damage Inflicted

Description
Fired 3 torpedoes on an 80 starboard track at an anchored AK
from a range of 1800 yards. Observed 3 hits - one amidships, one at
the bow and one at the stern. Target sank to bottom in less than a
minute and then rolled over on its side. Depth water - 10 fathoms.

Ship(s) Sunk
One AK similar to HAMBURG MARU - 5220 tons.

Fire Control and Torpedo Data

Type Attack
Periscope attack. Target was anchored in 10 fathoms of water.
Just prior to firing we went around at 60 feet keel depth. Fired
three bow tubes using 2° divergent spread at range of 1800 yards with
track angles of 82°S, 84°S and 82°S respectively. Keel depth 55'.
Apparently these torpedoes took no deep initial dive because all three
ran hot, straight and normal and 3 hits were observed.

Target Data - Damage Inflicted

Description
          Fired 6 torpedoes from bow tubes at a convoy of 2 AK's and one
escort, three at each of two AK's. 3 timed hits into leading ship which
was observed to blow up and sink in less than a minute. One timed hit
was scored on second ship in column although damage was not observed
until later when this ship was again attacked and ultimately sunk.

Ship(s) Sunk
          One AK similar to GOYO MARU Type - 8,469 tons. This ship
had apparently been altered to carry gasoline judging from the bright
fire and terrific explosion after being hit.

Ships Damaged or
Probably Sunk
          One AK similar to FLORIDA MARU. This ship was later sunk.

½ full - 3/4 set. Ships were in column about 600 yards apart with escort
astern and on starboard quarter of trailing ship. Fired tubes 1, 2, and
3 at leading and larger ship and then shifted targets and fired 4, 5,
and 6 at second ship. Swung with full left rudder to bring stern tubes
to bear but was forced down by escort before a new setup could be
obtained. Used a 2° divergent spread for 1st target and an initial
firing range of 1750. Range to second target was 2000 and fired on a 73
track using a 10° divergent spread. This target turned after the leading
ship was hit and the first two torpedoes were heard to pass ahead. The
third was heard to hit but the damage was not observed. Used periscope
bearings and radar ranges at the firing point.

Fire Control and Torpedo Data

Type Attack
Periscope attack. This originally started out as a radar ap-
proach but when it was found that the target had no way on and since
it was dark, it was decided to wait until daylight and make a peri-
scope attack. Target was drifting to South at about 0.5 knots. When
the range was 1800 yards swung to bring stern tubes to bear on the
target. At the time we fired the range had increased to 2200 yards. Fired tubes 7,
8, and 9 which were Mk 18 torpedoes. #7 was observed to broach about
200 yards away and ran erratic. 4 minutes and 27 seconds after firing
#7 and no hits had been made, fired #8. 4 minutes and 30 seconds
after firing #8 it was observed to hit the target just forward of the
bridge - torpedo run 2150 yards. #9 ran for 4 minutes and 57 seconds
before hitting and #10 ran 4 minutes and 38 seconds before it was ob-
served to hit. Injection was about 30°F. The torpedoes runs were:
#8 - 2310 yards and for #9 - 2150 yards and for #10 - 2310 yards.
Torpedo speeds of 14.3 knots for #8, 12.9 knots for #9 and 15.1 knots for #10.
Newport failed to tell us about this.

REMARKS:-
        Torpedo from #7 tube was seen to broach about 200 yards away
        and it continued to porpoise during its entire run. Believe this was
        due to a stick depth engine.

Type Attack
Periscope attack. Since target had an escort and since our
number 1 periscope is jammed in the up position, periscope observa-
tions were difficult. Just before firing, target zigged away over
70°. Since she was only about one minute along on a leg of a zig,
she apparently sighted us. Escorting plane forced us down and
dropped one bomb, fairly close.

Type Attack
Periscope Attack at night in bright moonlight. We were in cen-
ter of a convoy of at least 5 merchant ships with at least 3 escorts, one
of which was a light cruiser. Picked cruiser for 1st target and fired two
Mk 18's from stern tubes on a 95°S track at a range of 2500 yards using a
1° divergent spread. Gyros 174 and 176. Immediately shifted targets and
fired other two stern tubes at a freighter with a range of 1500 yards on a
112 starboard track using a 1° divergent spread. Gyros 193 and 193.5. One
hit was observed in the cruiser which caught on fire forward. Two timed
hits were scored on the freighter which, when last seen, was giving off a
cloud of black smoke and sinking. As soon as last stern tube was fired,
swung left to bring bow tubes to bear on third target which was an AK sim-
ilar in appearance to the MOMOYAMA MARU type. Fired two bow tubes on a
108 starboard track, with a 358 gyro, range 950 yards. Two hits were ob-
served and the target sank in a little over a minute. While searching for
second target in order to ascertain the damage, escorts started anti-
submarine measures and since we were all out of torpedoes, went deep and
started evasive tactics.
Contrary to our experience on March 3, the Mark 18's fired on
this attack ran normally and at the expected speed of 28.8 knots. Battery
temperature was about 60°F.

(K) MAJOR DEFECTS AND DAMAGE

In the heavy weather encountered off the Kuriles this was virtually
a two engine ship. Water was coming down the induction constantly in
a steady stream and as the two stills are directly under the forward
engine room induction which therefore had to be kept closed, we could
not use those engines.
The antenna support just couldn't stand the weight of the ice on
the antennas eventually giving way and the antennas were then broken
loose by the sea.
The JK head and Bendix log were unfortunate sacrifices in the
sinking of a Japanese ship. As it was snowing I was unable to deter-
mine the position in regard to the beach and also as there was an
escort present, I could not use the fathometer.
The fathometer receiver was inoperative a good part of the patrol
so we cross-connected it with the QC receiver which gave good results
except the QC range dial is not sensitive to readings under 100 fathoms.
The two occasions when we had to penetrate the ice fields after
Japanese ships made a shambles of the topside gear. Casualties were:
#1 periscope, the TBT's, the bridge gyro repeater, the lookout platform
supports, the masthead light and many stanchions and life lines.
Fortunately #1 periscope which was bent and jammed in the raised
position apparently funded the ice from the SJ antenna.
We were able to jack the upper bushing of #1 periscope up ten
inches to the point where the periscope was bent and cut it off
there. Then by driving it down in the shears we were able to lower
#1 two and a half feet below #2 when it was fully raised. This might
have been enough in flat seas but wasn't much help in the rough
weather where we were.

(L) RADIO

Off Paramushiru NPM faded badly on all frequencies. 16.68 kc
was completely useless due to very low signal strength and strong
interference from NPG, San Francisco. 9090 kc useless periodically
due to interference from strong unidentified stations. Japanese
interference on 14390 and 17370 kc, but NPM readable except for
long period fading.
All antennas carried away by ice off Paramushiru and for the
remainder of patrol all transmission and reception was done on the
SD antenna, which proved very satisfactory. NPM 16.68 kc readable
on DQ loop on correct headings only.
One case of attempted jamming noted while transmitting on
4235 kc.
NPM readable on DQ loop at 65 feet up to 1500 miles.
Had no success with CUO radar detector, with Dipole antenna,
off Paramushiru. Tuning seems excessively critical. Antenna was
flooded for remainder of patrol.

C-O-N-F-I-D-E-N-T-I-A-L

(M) RADAR

SJ-1 The SJ-1 radar was constantly troublesome during entire patrol.
    There were many tube failures and several grounds and loose connec-
    tions due to heavy weather.
    Some undetermined fault repeatedly caused the transmitter out-
    put and receiver tuning to vary erratically. This condition has
    existed in greater or lesser degree ever since installation, and it is
    considered advisable to install a complete new transmitter-receiver
    unit since facilities on board make location of such a trouble
    virtually impossible.
    When working correctly it frequently picked up land at ranges
    greater than 80,000 yards, but the greatest range obtained on ships
    was 14,000 yards (medium - large freighter).
    The antenna mast seems very loose in its bearings, causing
    excessive vibration at high speeds on the surface.

SD-4 The SD-4 radar proved reliable and fairly satisfactory during
    entire patrol in spite of fact that the antenna whips and loading
    condensers were bent badly by drift ice.

(N) SOUND GEAR AND SOUND CONDITIONS

    Port JK head was lost during an attack off Paramushiru.
    Sound conditions off Paramushiru were bad due to drift ice and
    shallow water.
    Conditions in Southern Okhotsh Sea were fair. Ice formations
    caused much interference.
    Off Honshu conditions were good.

(O) DENSITY LAYERS

    No density layers were encountered in the Kuriles except off
    Etorofu Kaikyo. Here sharp positive gradient at 100 feet and another
    at 140 feet were registered on the bathythermograph.
    Off the south coast of Hokkaido on March 8 encountered a
    density layer at 200 feet. On March 13, after attacking a convoy,
    no layers were found until 290 feet when a sharp negative gradient
    was registered that continued on down to 450 feet.
    The bathythermograph cards are only graduated to 30° water
    temperature while the water temperature off Paramushiru varied
    between 27° and 28°.

(P) HEALTH, FOOD AND HABITABILITY

In spite of the severity of the weather the health of all hands
was excellent. There were four sick days, two from gastroenteritis
and two from cellulitis.
The food was good with as much variety as can be expected in
seven or eight weeks at sea.
The boat was quite cold and damp when in northern waters. Sea
water temperature was 27° and the single hull portions of the boat
was ice constantly in the torpedo
room bilges and pipes containing water, such as shower drains, froze
solid.

(Q) PERSONNEL

The conduct of the personnel was exemplary. Without a doubt
the greatest single asset of the U.S. Navy is the enlisted man. As
has been said before the greatest morale factor in the submarine
service is the sound of your own torpedoes exploding in Japanese
ships. There were no unfortunate reactions to the sustained depth
charging on March 12.

(U) REMARKS

The winter clothing furnished submarines is woefully inadequate
for a northern winter patrol. A light weight fur-lined suit boots
included and waterproofed, is necessary. If it can't be made absolute-
ly waterproof then a complete coverall including hands and feet,
such as has recently been advocated as a life saving suit for the
merchant marine, should be provided. This is necessary as time and
again the entire bridge was chest deep in water. This warm clothing
is available to the aviators and after all, we are in the same navy.
The light grey paint is indispensable when playing around in
ice fields.
It would have been impossible to fire the guns at any time,
both from the rough weather and the fact that they plus the TBT's
were constantly covered with ice.
The night lighting on the TDC as installed by the Sylvania Co.
is adequate but not perfect.
The lubricating grease furnished is not suitable for this
climate. The periscopes, planes, etc. were extremely stiff.
The performance of the electric torpedoes at 30° temperature
did not agree with the table furnished. I would like to know if
those speeds and ranges were obtained by test or from a theoretical
battery curve.
The position of the convoy on the night of 12 - 13 March was
very interesting. It was in latitude 32-58N, longitude 138-42E,
course 255, speed 9. All ships were heavily loaded and from their
position and course it had apparently left Yokohama headed due
south and after passing outside of Mikura Shima changed course to
the southwest. This plus the track of the small convoy encountered
off Etorofu in the Kuriles seem to indicate the Japs are routing
their convoys about a hundred miles off shore instead of along the
coastline.
I was very disappointed in the results of our trip along the
100 fathom curve off the coast of Honshu. Although some of the time
we were some distance off shore, a lot of it we were quite close
and we usually had complete radar coverage between us and the beach
at night yet we saw nothing.

C-O-N-F-I-D-E-N-T-I-A-L
FIRST ENDORSEMENT to
CO SANDLANCE Conf ltr. SS381/
A16-3 Serial (05) dated 3-23-44.

From: The Commander Submarine Division TWO HUNDRED ONE.
To: The Commander-in-Chief, United States Fleet.
Via: (1) The Commander Submarine Squadron FOUR.
     (2) The Commander Submarine Force, Pacific Fleet.
     (3) The Commander-in-Chief, Pacific Fleet.

Subject: U.S.S. SANDLANCE (SS381) - Report of War Patrol
         Number One, comments on.

1. The first war patrol of the U.S.S. SANDLANCE was the
first for her Commanding Officer, Commander H.E. GARRISON as such.
This patrol was most outstanding in every respect. It consisted of
twenty two days in the Kuriles and Areas 1,2,3,4, and 5. During all
of the time in the area and most of the time enroute to the area the
SANDLANCE had to put up with extremely rough and cold weather, and ice
floes. In spite of this and intense anti-submarine measures, the
SANDLANCE by sheer intestinal fortitude, was able to turn in a most
outstanding patrol. The determination of the Commanding Officer to do
his duty was exemplified by the fact that during most of his time on
station, number one periscope was jammed in the fully raised position,
and his sound gear had been wiped off pressing home an attack in shallow
water. The skillful manner with which the many obstacles were overcome
is indicative of the Spirit and state of training of both officers and
men.

2. ATTACK NUMBER ONE.

Three torpedoes were fired from periscope depth at an
anchored 5,220 ton AK. Three hits were observed and the target was seen
to sink in less than a minute.

ATTACK NUMBER TWO.

Attack No. 2 was a night radar attack from radar depth.
Six torpedoes were fired from the bow tubes at a convoy of two AK's and
one escort. Three hits were made on the leading AK which blew up and sank
in less than a minute. One hit was made on the second AK but the extent of
damage was not determined because of being forced down by the escort. This
ship was contacted later and sunk.

U.S.S. SANDLINGS (SS381) - Reports of War Patrol
Number One, Concrete o...

ATTACK NUMBER SIX (continued)

sunk in a little over a minute. Following this attack the SANDLINGS was subjected to a sixteen hour depth charging, but sustained no serious damage.

3. It is noted that the SANDLINGS encountered constant right air problems in Areas 4 and 5, and that in some instances the planes were, in all probability, equipped with Radar.

4. Heavy weather and ice fields caused considerable damage by the ice close. Both 18'F, the bridge gun platform supports, stanchions and life lines are in bad shape. The JK head was ripped off and Baird's 10 sword can best when SANDLINGS hit bottom during the preceding attack in shallower water. The smoke canister broken loose by the weight of ice on the carton, remains true.

5. Too much emphasis can not be placed on the need for factory winter clothing and the remarks made by the Commanding Officer on this subject are completely concurred in.

6. The Commanding Officer, officers and crew of the SANDLINGS are most heartily congratulated for a beautiful patrol. The experiences, intensity and ability displayed on this patrol under most difficult conditions itself. From close analysis of this report and from further inquiry than that the SANDLINGS be credited with inflicting the following damage to the enemy:

SUB
1 CL  3500 tons
1 LK  5760 tons
1 AK  6000 tons
1 AK  5845 tons
1 AK  649 tons
1 AK  5220 tons

TOTAL 34,798 tons

COMSUBSPAC PATROL REPORT NO. 396
U.S.S. SANDLANCE - FIRST WAR PATROL.

From: The Commander Submarine Force, Pacific Fleet.
To : The Commander-in-Chief, United States Fleet.
Via : The Commander-in-Chief, U. S. Pacific Fleet.

Subject: U.S.S. SANDLANCE (SS381) - Report of First War Patrol.
(8 February to 23 March 1944).

1. The first war patrol of the SANDLANCE was the first
for the new Commanding Officer, as such. The patrol was conducted in
the Kuriles Chain and in areas off the northwest coast of Honshu.

2. In spite of the rigorous winter weather encountered
and patrolling in heavy ice floes, the SANDLANCE conducted aggressive
attacks both in the Kuriles Chain and in areas to the south. The at-
tack on the convoy in the early morning hours of 13 March was excep-
tionally well conducted.

3. It is believed that the latest type winter clothing
would have proven more efficient than the older type that was used by
the SANDLANCE.

4. The slow speed performance of the Mark 18 torpedo
reported by the SANDLANCE in cold northern waters is being investi-
gated.

5. This patrol is designated as successful for Combat
Insignia Award.

6. The Commander Submarine Force, Pacific Fleet, con-
gratulates the Commanding Officer, officers, and crew for this aggres-
sive and successful war patrol conducted in part under the most
rigorous weather conditions. The SANDLANCE is credited with having
inflicted the following damage upon the enemy:

A. PROLOGUE

     Arrived at Pearl Harbor from patrol 23 March.
     Seventeen day refit, three days training, sound tested and depermed.
     Ready for sea 20 April.

B. NARRATIVE

20 April
     1100VW Underway from SubBase with PC escort.
     1800VW Escort departed.

22 April
     1800X Arrived Johnson Island. We were five hours late as heavy rain squalls
           reduced visibility and created radar interference to such an extent
           we had considerable difficulty locating the island. Took on 14,000
           gallons of fuel oil.

23 April
     0600X Underway from Johnson Island.

27 April
     Received ComSubPac despatch diverting SAND LANCE.
     Changed course to proceed to rendezvous.

28 April
     Special mission cancelled. Set course for patrol area.

2 May
     1700I Entered area.

3 May
     0150 Radar contact at 19000 yards. Commenced tracking and it developed
           into one ship with one escort. Tracked until speed and zigzag plan
           were solved and then attacked. At
     0325 fired three torpedoes with a 90 starboard track, zero gyro and
           range of 1700 yards. No hits. I was stunned. I had expected to
           fire at 2200 yards so used a one degree spread which was too small
           for the range fired but there should have been three hits. The
           escort dropped a few random depth charges and made a nuisance of
           himself while the target maneuvered violently and we started an
           end around. We discovered the Bendix log input was about two
           knots low which introduced an error in the fire control setup.
           It was now a race against time as it was starting to get light.
           After gaining position on the bow, dove to radar depth and at
     0435 fired three torpedoes on a 100 track at 2300 yards, one hit.
           The target sank in seventeen minutes. The escort dropped a few
           heavy charges but was not persistant and we went deep and cleared
           the vicinity. The target resembled the CHICAGO MARU although I
           didn't see it by daylight. Pestered by trawler type patrol boats
           and a DAVE floatplane all the rest of the day. Forced to dive
           twice during the night by planes, apparently radar equipped.

4 May
        Shifted to next area north. Attempted to patrol on surface to increase
        coverage as we are almost 100 miles from Saipan but at
0715    forced down by plane, coming out of a rain storm, which dropped [UNCLEAR: 15]
        bomb as we passed 150 feet.
2300    Radar contact at 14000 yards. At 6000 yards it turned out to be
        something corresponding to our PC's, so broke off the attack and
        retired. Until we have a torpedo that will run at three feet we
        are helpless against this type of ship.

5 May
        Again tried to patrol on surface and again bombed, 120 miles away
        from yesterday's position but their air coverage is pretty thorough.
        For three nights we have had four to five plane contacts a night.

7 May
        Shifted areas.

8 May
2130    Sighted small patrol boat, evaded on surface.

8 - 9 May
        Patrolling in Saipan Channel. There is considerable air activity
        over Tenian Island. Sometimes as many as ten planes could be seen
        on one periscope observation.

10 May
        Shifted area. Patrolling off Tenian Harbor.
0710    Sighted a Chidori class TB, a trawler and a large sampan patrolling
        in a line of bearing. Attempted to attack the Chidori but got in-
        volved with the trawler which is probably just as well as our torpe-
        does couldn't be set shallow enough for this ship. The trawler was
        within 100 yards of us without detecting the
        echo ranging but passed without detecting the SAND LANCE. A great many
        planes over Tenian. I counted 34 in one periscope observation.
2125    SD contact closed rapidly from 16 to 4 miles. Dove.

11 May
0217    SD contact closed to 5 miles. Dove.
0325    SD contact closed to 5 miles. Dove. This is the heaviest air coverage
        I have ever seen. I wonder if we are just unlucky or the other boats
        are also getting this unwelcome attention. We have not had a contact
        in nine days, but have encountered intense anti-submarine measures.
        Either they are effective in keeping us down and slipping ships past,
        which I doubt, or some one in this group just ahead of us is doing
        damage and we are getting the results of the hornet's nest.
1440    Sighted masts through the periscope. Contact developed into large
        four goal post freighter resembling KYUSYU MARU and a large gun boat
        with four surface and four air escorts. At
1514    fired four torpedoes at the large ship. I intended to fire the other
        two at the gun boat but we lost depth control at that point; however,
        I fired the two torpedoes by sound. I heard two hits on the freighter

but all the people below reported three hits. No hits on the gun boat.
The heavy screws stopped immediately and never restarted and sound re-
ported breaking up noises later. I could not check this being very
busy with evasive tactics as at this point all hell broke loose. I
have never personally been subjected before to such a concentrated at-
tack as all the planes and at least two of the escorts started dropping
simultaneously. Outside of a severe shaking up a few lights and gauges,
etc. no real damage was done. We went to 450 feet and were able to clear
the area after dark in spite of several plane contacts.
2000 Forced down by plane.

12 May
After broadcasting our intentions on kcs, we entered adjoining
area to help work on convoy reported heading for Saipan.
0030 Sighted patrol boat. We played tag for an hour and a half, apparently
tracking each other by radar. We finally put on full speed, made a
radical course change, and lost him. At
1405 while patrolling off Saipan looking for convoy, we heard about forty
depth charges eight to ten miles away. We could see three trawlers
patrolling to the south heading in our direction.
1623 Upon raising the periscope for an observation, received three bombs,
very close, immediately followed by twenty one depth charges, also
close. We evaded at 400 feet and about twenty more charges were
dropped some distance away. On the previous observation, the traw-
lers were about 2500 yards away but they must have closed undetected
by sound. I guess that's what we get for not staying in our own area.

13 May
Shifted areas. We have been discovering minor damage all day from
the depth charging but I think the only real casualties are the JP
sound receiver and the Bendix log.

14 May
Patrolling off Apra.
1305 Sighted smoke over the horizon plus two sets of echo ranging. Con-
tact developed into two medium freighters, heavily loaded, heading
for Apra. Two SC type plane and one trawler escorts, one 4 engine patrol
plane and one BETTY air escorts. At
1427 fired four torpedoes at leading freighter, MITAKESAN MARU type, 1300
yards, 50 port track, two hits. One escort was on the quarter. zero
angle on the bow so could not swing the stern tubes at the other
ship. Started down amid the usual depth charging and bombing. We
were quite close to the ship and our swing took us in to 300 yards
just as the ship started to sink. That was worse than the depth
charging. The terrific cracking, groaning, and popping noises were
almost as loud as the depth charges and so close I for one
thought the ship was sinking right on top of us. There was no question
about that one sinking. Evaded at 450 feet.
We are now in the unfortunate position of having eight torpedoes
aft and none forward. That requires room for maneuvering so I'll have
to play the convoy lanes rather than the harbor entrances from now on.

14 May (cont.)
     We have had to survive and one moderate depth charging and bombing
attacks in four days. This plus the constant air screen has the
crew pretty jittery. If we are attacked again in the next two
or three days, I’ll have to pull well clear and give all hands a
couple of days to settle their nerves.

15 May
0010    SD contact closed fast to three miles, dove. Made three separate
attacks a half hour apart before I lost us again.

16 May
1850    Strolling off Saipan.
        Immediately after surfacing at night made an SJ contact at 23000
yards right off the entrance of the harbor. It appeared to be
time ships headed southwest. I started and ran in-
mediately became engaged in duel with a freighter running
air coverage. Every time I got within 15000 yards we were forced
down. I stayed down for fifteen minutes and then surfaced and ran
full speed for fifteen minutes always managing to stay within radar
ranges. After being forced down five times in two and a half hours
I finally apparently had complied with instructions to escort fifty
miles in-approach, so I started and ran around. At

2330    gained position ahead and commenced approach. [UNCLEAR: text]
        The escort was necessary and only having
torpedoes aft complicated things. There was one escort patrolling
chard and one on each quarter, at least three large ships apparently
in a line of bearing. Just as we got inside the leading escort
and started to swing for a shot, the convoy zigged forty
degrees giving me no choice except to continue out in front of the
escort on the quarter. It was too dark to see by the purpose so
we would radar ranges and bearings throughout, hoping our one op-
erating set of sound gear on the escort on the quarter. At

0025    first four torpedoes on a port track at 2800 yards. Two observed
hits. Then the scout approached to 1200 yards, went deep but the
depth charging was very light. At

0052    heard a heavy muffled explosion followed immediately by the noisy
scraping and popping of a ship’s breaking up. The screws stopped
at the first hit. This ship could not be identified but from the
initial radar range I estimated at least 6000 tons. After avoiding
the escort, we surfaced at

0110    to close to the convoy. Unfortunately the SD radar chose this opportunity to fail for an hour. I ran out the base course of the con-
voy and at

0250    half arrived for the ship off the ship off the contacts on the SD,
finally forcing us down at

0325    past a half hour before morning twilight. At

0640    surfaced with no planes appearing on radar. Commenced search and
soon sighted smoke over the horizon. Started a wide and around at
full speed down by a plane. At

1215    surfaced and again was able to make a sonic contact, so again started
an end around. At

17 May (Cont.)
1310 a plane dove out of a cloud directly at us. He had a beautiful shot
     but his aim was lousy and he missed by several hundred yards. There
     was intermittent bombing during the afternoon to keep us down.
1745 surfaced and started a search. They have at least three times
     so it looks bad. This outfit has had at least three times
     for air coverage since daylight and we are 120 miles west of Saipan.
     At almost
1910 heard some distant depth charging. Some one else working on our
     convoy as we sent a contact last night. At
1942 made SJ contact at twenty thousand yards. As we closed we found
     that two large ships were stopped and three escorts patrolling around
     them. It was too dark to see well but one was low enough to be a
     tanker so I considered a look [UNCLEAR: down] track so tried a surface attack. At three
     thousand yards the escort passed 1500 yards ahead but did not see
     us so I swung for a stern shot. Just then the other ship turned
     to periscope depth the ship was seen. [UNCLEAR: I chose that] tanker so I chose that
     necessary to determine the track so tried a surface attack. At three
     thousand yards the escort passed 1500 yards ahead but did not see
     us so I swung for a stern shot. Just then the other ship turned
     to periscope depth the ship was seen.
2114 us so I dove, shooting four torpedoes on the way
     down. One sure hit, another doubtful. The depth charging was
     heavy but short. On surfacing the ship was still
     burning fiercely. When we surfaced and left the vicinity one hour
     and fifteen minutes later it was half submerged but still burning.
     This was about a six thousand ton freighter. A contact report
     shortly after we surfaced indicated that the earlier might have made
     the earlier attack on three ships, damaging one. If this is the
     same group, her damaged ship sank before we arrived because there
     were only two when I attacked and both seemed in good shape.

19 May
0900 Departed area.
2100 Received orders to proceed to Fremantle, Australia, for refit.

20 May
0710 Forced down by planes.

21 May
1405 Forced down by planes.

22 May
0955 Forced down by planes. They seem to be covering this whole section
     of the Pacific pretty thoroughly as we are well away from any land.

23 May
     Came under command of Commander Task Force 71.

27 May
     Passed through Pitt Passage during the night. Radar showed eight
     to ten small pips but we did not come close enough to see whether
     they were fishing or patrol boats. Positive indication of one or
     more radars present of approximately the same frequency as our SJ.
     We have received no notification of another of our submarines in
     this vicinity. If there is none, the Japs have a new radar of much
     higher frequency than previously noted.

C. WEATHER

The weather was excellent throughout the entire patrol.

D. TIDAL INFORMATION

1. A 1 knot current setting NE was encountered to westward of Farallon
   de Medinilla to a distance of 20 miles.
2. Current in Saipan Channel amounted to 2 knots setting NW during flood
   and 1/2 knot setting SE during ebb.
3. All other currents were found to be as listed in the Sailing Direc-
   tions. Times of change in tides appeared to agree with Tide Tables.

E. NAVIGATIONAL AIDS

1. Tenian light is not lighted.
2. Light at Garapan Harbor on Saipan was not lighted.
3. Point Ritidian light on Guam was not lighted.
4. Orote Point light on Guam was not lighted.
5. Tangents on most of the Marianas are well defined and give good cuts.
   SJ bearings are very helpful at night in keeping positions.

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS

The anti-submarine measures around Saipan and Tenian were quite vio-lent. There has been some wonder expressed in the press about the absence of Japanese planes during our task force attacks. I can tell them where the Japanese air force is, it is on Anti-submarine patrol. The entire area was thoroughly covered day and night, there were planes covering all convoys entering and leaving and in addition numerous surface patrols. A couple of good workings over gave me a thorough respect for their anti-submarine forces in this vicinity.
After thinking over the attack made on us off Saipan on 12 May I'm convinced I walked into that one leading with my chin. A plane had spotted us and coached on the trawlers. We saw them approaching but plotted them to pass 2000 yards ahead but when they got ahead they ap-parently headed right at us. The combined attack was too thorough and too beautifully executed to have been accidental. The only thing that saved us was that we had reversed course ten minutes before and they still had us plotted on the other one because after the first half dozen bombs arrived at the periscope the rest and the depth charges were all a couple of hundred yards astern.
When the going gets tough, I'm still convinced that with the present Japanese depth charges, the best protection is a layer of water 450 feet thick between them and me.

K. RADIO

Reception of NPM generally satisfactory, with strong morning and evening fading on 9090, 14390 and 17370 kcs. 6380 proved very good for night reception. 16.68 kcs readable up to about 2000 miles from Pearl. Statie was bad on 450 kcs. Only two strong signals were received.
The CUO Radar Detector picked up signals on 364, 138, 108 and 76 megacycles. The 138 and 76 mc radars were believed to be aircraft con-voy escorts.

L. MAJOR DEFECTS AND DAMAGE

There are two items of equipment on this ship which have been un-
satisfactory since the first day of operation. One is the Bendix log
which is worse than useless because no information would be better than
false information. The Bendix representative at Portsmouth admitted he
could do nothing with it and we have found no one since then who could
improve the situation. The other one is the SJ radar which has been
pampered like a sick old lady by all the radar experts who have
ever been on board. All the radar ex-
perts have examined it, made a
few passes, looked wise and said it was
all right while it continued as unsatisfactory as ever. This has been
going on for nine months. Fortunately I have capable radar personnel
on board and by virtue of hundreds of man hours of extra work they have
kept it in operation most of the time.
Defects requiring correction prior to next patrol are:-
Overhaul of JP receiver.
Grounded QB sound head which was installed last refit.
Flooded JK sound training motor.
Leak in SD mast.
New cables for #1 periscope.
Leak in #3 main engine cooler.
Leak in after hydraulic supply line.
#1 main engine overhaul.

M. RADAR

SJ Radar: The same erratic operation of this gear as experienced
on the first patrol was again a source of constant trouble. The total
time that the set has been out of commission has been small, but it has
all been when the set is first turned on upon surfacing. Careful check-
ing of the gear has failed to disclose the
source of the trouble. It is believed that the trouble is in the R-F
plumbing or antennae assembly. When the gear is operating normally,
very good results are obtained.
SD Radar: Soon after entering the area, trouble developed on
this gear and it was determined that the mast was leaking. The mast
shows no evidence of having been damaged by depth charges, but megger
readings of the mast vary from 10,000 to 200,000 ohms depending upon
the length and depth of the dives. Constant tuning to meet the varied
loading has kept the set picking up planes at an average of from 8 to
10 miles.

N. SOUND GEAR AND SOUND CONDITIONS

The QB sound head suffered a broken and grounded lead during depth
charging.
The QC training motor flooded out and had to be replaced by the QB
training motor.
The JP sound receiver was consistently less sensitive that the JK
head, and finally failed completely due to condenser trouble.
Sound conditions were good during entire patrol. Several echo
ranging signals were picked up at extreme ranges. These frequencies
varied from 17 - 19 kcs.

C-O-N-F-I-D-E-N-T-I-A-L

C. DENSITY LAYERS

On routine dives only very gradual thermoclines were found, amount-
ing to as much as 2° negative gradient at 200 feet. However, on deep
submergence during evasion rather sharp negative gradeints were en-
countered at from 230 to 300 feet, and in some instances amounted to 6°.

Seas were smooth and air temperature usually was lower than water
temperature at the surface.

Date Lat. Long. Depth Gradient Time
5/2/44 15-30N 145-40E 320' -3° 2030 GCT
5/11/44 15-00N 145-30E 230' -5° 0900 GCT
5/12/44 15-30N 145-25E 240' -4° 0800 GCT
5/17/44 14-55N 142-30E 280' -8° 1200 GCT

P. HEALTH, FOOD, AND HABITABILITY

The health of the crew was excellent.
The food was good. The greatest complaint is that a good deal of
the meat is pretty well wrecked before we get it. There must be a
bunch of shipfitters doing the butchering of this boned meat. The cuts
are exactly the opposite of anything I have ever seen. A single cut
will be loin at one end and stew meat at the other.
The new ice cream freezer was a decided help.
The ventilation of the forward battery compartment on this ship,
and I suppose others of it's class, is pretty bad. On a patrol in the
tropics the heat from the battery becomes stiffling. Stepping into
this compartment from either adjacent one is equivalent to being slap-
ped in the face with a wet steaming towel. I strongly recommend a
couple of small air conditioning units similar to those in the conning
tower being installed in this compartment.

Q. PERSONNEL

The conduct of all personnel was, as usual, worthy of nothing but
the highest praise.

   Limiting Factor of this patrol - Torpedo Expenditure.

U.  RELATERS
   During this patrol I accepted the very distinctive sound of a ship breaking up as evidence of sinking, in each of the three instances after two hits. On one occasion I was not able to shoot personally as we were busy evading but on the others it could plainly be heard through the hull. With the plans there are probing this area, it is very seldom possible to stick around and witness results of an attack. I realize that this is not positive evidence and that later information may show that one or more of those ships was only damaged. Also I was prolific with torpedoes using four instead of three fish as regards the intense air coverage necessitated such brief and infrequent periscope observations I was not too confident of the data obtained.

   There is no question that continuous echo ranging by the escorts is a tremendous aid in locating convoys before they are visible through the periscope and seems very ineffective in locating a submarine. I wonder if the enemy submarines have the same experience with our forces.

   As can readily seen from this report, I have become intensely plane conscious. A major source of concern to me is the impulse bubble which I have not been able to completely eliminate. It is a little disconcerting during an approach on an air escorted target to realize that the hunting torpedo which you are setting up a beautiful shot, by deliberately taking solid water through the upper valve but couldn't completely eliminate the bubble. I would be willing to try to increase initial velocity to barely enough to clear the tube at periscope depth if it would mean breaking the impulse pressure to a point where the bubble would not ordinarily remain.

   Also our planes are going to make a night raid, if any submarine present was notified in advance, it would be an easy matter to notify the planes of the recognition signal for that night as the Japanese planes use it continuously after sunset.

CONFIDENTIAL
FIRST ENDORSEMENT to
USS SAND LANCE Report
of Second War Patrol.

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

Subject: U.S.S. SAND LANCE (SS-381) - Report of Second War
Patrol.

1. SAND LANCE second war patrol was of 46 days' duration.
Having expended all torpedoes in 16 days in the assigned patrol areas
in the Marianas, SAND LANCE was ordered to proceed to Fremantle for
refit. Area coverage was thorough and well conducted in the face of
heavy enemy air cover and anti-submarine activity.

2. Through determined and aggressive tactics, SAND LANCE
pushed home six torpedo attacks on escorted enemy ships, five of which
were successful. All attacks were skillfully conducted. Prompt enemy
counter measures prevented observation of damage except on the second
attack when the enemy was observed to sink.

3. It is fortunate that the encounter with the A/S air and
surface team on 12 May, and the bombing by the plane which got in to
close range undetected on 17 May, did not have more serious results.

4. SAND LANCE arrived in very good material condition. Con-
siderable routine refit work had been accomplished by ship's force en-
route. No. 1 main engine will be overhauled and number one and number
two main engine mufflers will be replaced. It has been necessary to
replace all brushes on #3 main motor; excessive brush tension as high as
six pounds was found. The brushes on the other three Elliott main motors
experienced previous trouble with main motor brushes; the rivets loosen re-
sulting in poor electrical contact between brush and brush shunt and
eventually clip breaks off at rivet hole. Main ballast tanks #4 and #5
will be converted to fuel ballast tanks. It is expected that refit work
will be completed in normal two week period.

5. The state of health and morale of the crew is excellent.

6. The Squadron Commander takes pleasure in welcoming SAND
LANCE and congratulates the Commanding Officer, Officers and Crew on the
completion of the second consecutive outstandingly aggressive and determined
patrol and on the important damage inflicted on the enemy.

U.S.S. SANDLANCE - Report of Second War Patrol -
Comment on.

1. The Second Patrol of the U.S.S. SANDLANCE was con-
ducted in the vicinity of the MARIANAS ISLANDS. Remarks of
the Commander Submarine Squadron TWELVE are complete and are
concurred in.

2. SANDLANCE's determination to inflict the utmost
damage upon the enemy is evident in every action of this out-
standing patrol. In spite of heavy air and surface anti-subma-
rine activity, all contacts were exploited to the greatest

USS SANDLANCE (SS381) 2nd War Patrol
Date of Attack: 11 May 1944
Position: West of GUAM

          In an attack on an AK on 11 May 1944
SANDLANCE scored two hits but due to loss of depth
control did not observe results. Although break-
ing up noises were heard, credit for damage only
was assessed. The damaged ship was believed to be
the KYUSYO MARU class of 6500 tons.

          DNI lists JII credits the SANDLANCE
with sinking the NITAKESSAN MARU on this day. Also,
Japanese verification lists show that the ONTAKE-
SAN MARU (tonnage unknown - possibly the same ship)
was sunk at the same time and in the same position
as the SANDLANCE attack. The SANDLANCE has been
credited with sinking the NITAKESSAN MARU on 14 May
1944. DNI and Japanese verification lists agree
that this ship was the KOHO MARU (4,291 tons).

          Recommend that the damage credit to the
SANDLANCE for her 2nd war patrol be readjusted to
the following:

                                            DAMAGED

A. PROLOGUE

     Arrived Fremantle, Australia, from second war patrol on 5 June.
Nineteen day refit by GRIFFIN and Division 121 relief crew. Major
items were conversion of #4 main ballast tank, renewal of two main
engine mufflers and installation of a new SJ transmitter. Four days
training, sound tested but not depermed. Ready for sea on 2 July.

B. NARRATIVE

3 July
1600 Underway for night radar approaches in exercise area.
2300 Completed night exercises, departed for patrol in company with two
     other submarines.

6 July
0650 Anchored in lee of Muiron Islands. COD came alongside and received
     12,000 gallons of diesel oil.
1000 Underway.
1240 Secured alongside fuel barge in Exmouth Gulf and delivered 60,000
     gallons of diesel oil to barge.
2010 Underway.

9 July
2040 Exchanged calls with friendly submarine.

10 July
1410 Exchanged calls with friendly submarine.

11 July
0950 Moored to dock at Port Darwin, Australia.

12 July
0530 Underway for patrol area having received 110,000 gallons of diesel
     oil.

14 July
1025 Made contact with a convoy of three AK's with three PC escorts.
     We had a large angle and were quite a ways out but by hanging on
     until they zigged toward us, we finally managed to get within range.
     The leading ship was a large AK and at
1137 fired three torpedoes at it, then swung and fired three at the
     third ship, a medium AK. At

14 July (Cont.)
1139-20 two observed hits on the large ship and at
1139-55 one timed hit on the medium AK. The large ship exploded in a
tremendous burst of flame and smoke, apparently carrying gas-
oline or fuel. As I was watching this spectacle the near escort
sighted the periscope and headed for us at high speed. We went
deep and the first four charges were close but by the time we
reached 450 feet they were well astern. When last seen, the
other freighter had stopped and swung so the bow was pointed at
us, so the extent of damage was undetermined but I do not believe
it was fatal.

15 July Patrolling off Kendari.

16 July Enroute area.

17 July
0840 SD contact closed to five miles. Dove.
1205 Sighted a BETTY, he did not close so did not dive.
1220 SD contact closed to six miles. Dove. This was another plane as
we could still see the first one.
1714 Sighted a BETTY. Dove then he closed to seven miles.

19 July Patrolling off Casilan Strait.

20 July Patrolling off Tapiantana Strait.
0520 Just at daybreak sighted a large ship with two Chidori Escorts.
The ship was circling in a tight circle with the escorts off to
the sides pinging, apparently waiting for daylight. As we closed
the range to 7,000 yards the sea was very calm, I only had one
more look as I crossed ahead of one escort. At
0639 fired four torpedoes on a ninety track, eleven hundred yards range.
No hits. No hits with a set-up like this is inexcusable and I have
none to offer. I have tried to find a reason for four misses but
can not. I had no opportunity to check speed so used ten knots
with a spread to cover from five to fifteen knots and gave check
bearings during the firing. Two minutes and ten seconds and fifteen
seconds later two torpedoes not hit the target and this was too quick
all fish running, they did not hit the target and this was too quick
for end of run so I have no explanation to offer for this. The
escorts gave us a short but very severe depth charging. Two of
them felt as though they were inside the boat. They blew the log
sword arm through the housing into the torpedo room and we took
considerable water before we could get it stopped in addition to
flooding out all the sound gear. There was a fair leak in the main
induction and both stern tubes leaked badly. Conversely they stopped
the periscope leaks and cleared a zero ground on the bridge repeater.
Although we were momentarily on the ropes they did not follow up
their advantage but conducted a super sonic search for several hours.
a complete fiasco for both sides.

21 July Patrolling off Basilan Strait.

22 - 23 July
Patrolling down island chain toward Jolo.

24 - 27 July
For four days we have practically worn a path back and fourth
across the Celebes Sea attempting to make some contact. We
have faithfully kept noon positions but have not seen a ship.
The only tangible result is to use a lot of fuel and practically
burn up #3 main motor, which reduces our maximum speed to
seventeen knots.

27 July
1540 Two small vessels resembling YMT's came through Banka Strait loaded
down with crates and stores. They were covered by two planes, one
looked like a Zero - the other was a DAVE.

28 July Patrolling off Banka Strait.

29 July
0120 Exchanged recognition signals and calls with friendly submarine.
Spent the day patrolling south of Lembeh Strait.

30 July Patrolling in Mondao Bay. This bay is being patrolled by a DAVE
floatplane and several small patrol craft but I don't see why as
there is no shipping here.

1 August Patrolling south of Lembeh Island.
1240 Heard pinging to the southward.
1305 Sighted three medium AK's with three escorts. The ship' were
hugging the coast and the escorts were in a parallel column to
seaward and unfortunately I was also to seaward of them. As the
forward end of the TDC is out of commission and I had eight fish
aft, I decided to try the stern tubes. At
1322 I fired four torpedoes. As I fired seven hundred yards dead
ahead of one escort I had to go down and could not watch the
results. At 1324 - 08 and 1324 - 18 heard two hits. Sound
reported one torpedo running erratic and two minutes later
there was another explosion, probably end of run. The search
was not very persistant but on returning to periscope depth,
the area was being closely patrolled by a DAVE floatplane so I
could not get any further information.

2 August Patrolling in the bay north of Lembeh Island.

3 August Patrolling in Amoorang Bay. At
0805 sighted two medium froighters with two escorts, and one DAVE
flying overhead, entering the bay. Commenced approach. We
were in a beautiful position, close to the beach with the
freighters between us and the escorts. At 0817, about two to
three minutes from the firing position while at 65 feet with the
periscope housed, two bombs landed close aboard. We wont deep
but as the bay is alandlocked on three sides with a fairly
narrow entrance, the escort had no doubt as to our position
and course so we had a fair working over in the hour it took
us to clear the bay. I'll have to chalk up one for the Japanese
aviators for this performance.

4 August At daybreak we started a search for the ships seen yesterday
but we found the wrong party. At 0635 dove for a plane at
nine miles. Almost ten minutes later a bomb landed pretty
close. Either he could see us at 200 feet or he was pretty
lucky.

6 August Sighted two freighters with two escorts proceeding very close
1440 to the shore line. Commenced approach. With the range at
thirty-five hundred yards it commenced to rain in solid sheets
reducing visibility to two hundred yards. As I was only 3500
yards from the beach the background noise was too great to fire
a torpedo. When the rain let up a half hour later they were no
where in sight. I believe I'm jinxed this patrol.

7 August Having found a place with deep water close to the beach I started
a submerged patrol 800 yards off shore. At 0855 sighted two
freighters with two escorts and one DAVE floatplane. As I know
they would have to come right past me, after the initial sighting
I took only one look, at 5500 yards, and stayed below one hundred
feet. As they closed I came up for a firing bearing, when at 70
foot I heard something I don't care to hear repeated. Everyone

7 August (Cont.)
in the conning tower distinctly heard the splash of the first
bomb about three seconds before the explosion. Two bombs went
off directly under the stern and blew the whole ship about three
feet in the air. I started down and as we passed 300 feet the
escorts started depth charging. The port reduction gear sounded
like a cement mixer so that both main engines had to be stopped.
controllers were jammed by a broken washer so the maximum speed
on that side was two thirds. At 430 feet we discovered that
#6 torpedo was running hot in the tube, the tube was so hot it
couldn't be touched with the naked hand. It could not be fired
at that depth so, in spite of the escorts' attacks, it was neces-
sary to come up to 150 feet. The torpedo was jammed so that it
would not fire at 150 feet with 500 lbs. impulse pressure. Upon
firing and the torpedo prematured eight seconds after firing,
which did not help our already bat-
tered stern. Four of the six forward fish had bent gyro spindles
and had bent the guide stud and lifted the stop bolt but for-
tunately did not start running in the tube. There was also the
usual miscellaneous minor damage. After dark we surfaced, cleared
the area, fixed the torpedoes and starboard controllers but have
been unable to find the trouble in the port reduction gear.

8 August Have spent two nights lying to, trying to fix the port shaft but
without any success. As it makes a prohibitive noise even when
running free with no power on that side and it is very difficult
to maneuver submerged on one shaft, I have decided to return to
Fremantle. By using #4 motor as a dynamic brake we can slow
down the port shaft enough to make twelve knots on the starboard
side without it pounding too badly.

9 August
2110 Exchanged recognition signals with [HANDWRITTEN: friendly submarine].

13 August
1130 Completed transit of Ombai Strait.

19 August
0915 Moored alongside U.S.S. GRIFFIN, North Wharf, Fremantle, Western
Australia.

C. WEATHER

    Weather conditions generally as described in Sailing Directions.
    Overcast about 80% of time in area. Frequent rain squalls. Glassy
    seas.

D. TIDAL INFORMATION

    Currents closely followed Current and Pilot Charts. Currents set
    east and west through Sulu Archipelago channels, depending upon ebb
    and flood of tide. The same holds true along northern Celebes, but
    with less dependability. Currents along northeast coast of Celebes
    appear to follow shoreline, setting northward. They do not appear
    to change direction, but only vary in velocity with the ebb and flood
    of the tide.
    There is a definite WSW current of about 1.5 knots in the north
    central and northeastern Celebes Sea, and an ENE current of about 1.5
    knots in the south central and southeastern Celebes Sea.

E. NAVIGATIONAL AIDS.

    No navigational lights were observed to be lighted. Sibago Light
    is in place but is dark. No other navigational aids were sighted.

H. ATTACK DATA

     See torpedo attack forms - pages 16 through 23, inclusive.

I. MINES

     No mines nor mining operations were noted.

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS

     They are unquestionably setting their charges deeper. On 20 July
we were at 420 feet and eight went off very close, in addition to
damage listed elsewhere, the entire hull vibrated like a tuning fork.

     That maneuver on the morning of 20 July is worthy of note. The
ship was steaming in a circle with escorts lying to about 2000 yards
on each side apparently waiting for daylight. This would be very con-
fusing to someone making a radar attack.

     While there aren't any airports on the north western end of the
Celebes, there is one or more floatplanes based in one of the bays
along there which cover, very effectively, the coastwise shipping.

C-O-N-F-I-D-E-N-T-I-A-L

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS (Cont.)

     The ships along here are small and hug the coast closely; by that,
I mean within two hundred yards where possible. They also follow every
little contour of the shore.

     I believe the Japs are using Amoerang Bay as an anchorage more
than Menado. I was never able to get close enough to see inside the
anchorage by Lembeh Island.

K. MAJOR DEFECTS AND DAMAGE

     The port shaft has been mentioned in the narrative. Either the
gears are cracked in the coupling between #4 motor and the reduction
gear or severe misalignment has developed.

     The stern tubes require repacking. This was done to both by the
ship's force while in Darwin and again to the port shaft in the area.

     For two patrols we have had trouble with #3 main motor. While in
the area it overheats excessively and draws most of the load. It must
be trouble with the cooler as we could not cause it to recur while in
the cooler waters off Fremantle.

L. RADIO

     Heavy interference both from Japanese stations and from weather
conditions greatly hampered reception during the patrol. All our re-
ception was made on 9250 kcs. 4370 kcs is practically useless after
crossing the equator due to Japanese interference and the apparent low
power used on this frequency. Unable to hear VIXO on 16150 kcs at any
time.

     On July 26 reception was near impossible due to above mentioned
reasons, when just after the submarine schedule started VIXO's trans-
mitter started keying improperly. It ran that way for two to three
hours with no attempt being made to correct the trouble.

     This vessel suffered no material trouble in either receivers or
transmitter.

     On August 9, attempted to transmit to VIXO on 12705 kcs
but couldn't raise him.
We shifted to 4235 kcs and had signal strength 3 both ways. We were
east of Celebes Island.

C-O-N-F-I-D-E-N-T-I-A-L

L. RADIO (Cont.)

          At various times during patrol we heard signals on 2880 kcs voice
but due to weather and Jap interference, were unable to understand what
was said. On August 8th we did manage to hear and copy one message
from "Sammy" to "Maize". Believe CW (Continuous Wave) transmission on
this frequency with low transmitting power would be more satisfactory.
450 kcs CW has been used with good results as an area frequency.

          We kept a close watch on the Radar Detector but only picked up
one radar on 610 megacycles off the northeastern tip of Celebes Island.
Through the Ombei Passage we picked up no enemy radar.

M. RADAR

          The SJ radar was more dependable this patrol, its total time out
of commission being approximately ten hours.

          The SD radar picked up planes from 20 to 40 miles and land to the
end of the sweep. Operational difficulties were a minimum. A blind
spot from approximately 20 to 14 miles resulted in several planes being
sighted that were not picked up. Operating the set 5 seconds out of
each minute gives good results with no signs of being DF'ed.

N. SOUND GEAR AND SOUND CONDITIONS

          On July 20th, Bendix Log sword arm was blown into the boat shower-
ing the after end of the forward torpedo room with salt water, flooding
both training motors, MCA driver, emergency receiver and the starting
panel for the MCA motor-generator.

          Both training motor armatures and field coils were washed out
with fresh water and baked. The starboard motor armature baked out to
1000 ohms resistance. We put this motor on the JK shaft, but having
low resistance burned out one armature coil. Replaced this armature
with one from the port motor, with 1500 to 2000 ohms armature resis-
tance. This system worked for 4 days submerged. No spares for these
motors are carried on board. Emergency hand training was used for the
remainder of the patrol.

          MCA driver and starting panel were cleaned enough to allow equip-
ment to operate to obtain soundings. All equipment needs overhauling
and careful check.

          Majority of patrol run was made near land and we were troubled
by land noise and schools of fish. As a whole, sound conditions were
good throughout the run.

C-O-N-F-I-D-E-N-T-I-A-L

N. SOUND GEAR AND SOUND CONDITIONS (Cont.)

On August 3rd during attack sound picked up what appeared to be
either a CC or fathometer. We were unable to determine his frequency
but found it to be below 13 kc. when we attempted to zero beat the
signals with our receiver. The escort was a small torpedo boat or a
fishing trawler. We also heard this signal on August 7th.

JP-1 sound equipment was practically useless in areas close to
land due to its high sensitivity. Each explosion usually left the re-
ceiver with high voltage ground.

O. DENSITY LAYERS.
Density layers as follows were found upon going deep during
evasion:

FIRST INDORSEMENT to
U.S.S. SAID LANCE (SS381) -
Report of Third War Patrol.

From : The Commander Submarine Squadron TWELVE.
To : The Commander in Chief, UNITED STATES FLEET.
Via : (1) The Commander Submarines SEVENTH FLEET.
(2) The Commander S.W. PACIFIC FLEET.

Subject : U.S.S. SAID LANCE (SS381) - Report of Third War
Patrol - comments on.

1. The third war patrol of SAID LANCE, conducted in
the Celebes Sea was of 46 days duration of which 31 were spent
in the patrol area. The patrol was aggressively conducted
despite the handicaps of smooth seas and enemy air cover. Thir-
teen torpedoes were expended in four attacks on escorted enemy
ships before the patrol was terminated due to main propulsion
derangements resulting from a combination of aircraft bombs,
depth charges, and the premature explosion of a Mark 18 torpedo
fired from #8 tube following a hot run in the tube.

2. Attacks #1 and #2. After a forty hour run at high
speed to intercept an enemy convoy, SAID LANCE made contact
and succeeded in delivering submerged attacks on this convoy
escorted by three PC escorts.
which was made up of three AK's and two YULIDORI type escorts.
Three torpedoes fired at the leading ship, a large AK, resulted
in two observed hits which caused the ship to blow up. Three
torpedoes were fired at another AK in the formation and one
timed hit was heard. SAID LANCE evaded the depth charge attack
of the escorts at deep submergence.

Attack #3. About daybreak of 20 July, radar contact
was made with a large AK and two YULIDORI type escorts. SAID
LANCE made a submerged approach and due to smooth
seas and maneuvers of the escorts, was unable to get a good speed
estimate. A spread of four torpedoes set at 10 feet were fired
and all missed. Subsequent severe depth charging by the escorts
was successfully evaded at deep submergence though considerable
water was taken into the torpedo room when the pitometer log
sword arm was blown into the ship.

Attack #4. This was a submerged attack on a convoy
of 3 AK's and 3 escorts. Four torpedoes were fired at one of
the ships and two timed hits were heard.

On two other attempts to attack enemy convoys SAID
LANCE was detected by escorting planes and bombed. On the second

occasion two bombs exploded close to the stern, damaging the
port shafting and jamming the starboard controller in the 2/3
speed position. While evading the subsequent depth charge
attack at 430 feet it was discovered that the torpedo in #8
tube was running. It was necessary to plane up to 100 feet
to eject this torpedo from the tube and approximately eight
seconds after firing, this torpedo prematurely. This explosion
further aggravated damage already incurred.

3. The health and morale of the crew is of a high
order.

4. The SAID LANCE will be refitted by the U.S.S.
GRIFFIN and Submarine Division 122-1 Relief Crew in the normal
period. The SAID LANCE returned from patrol with the port
shaft out of commission. A severe thump is reported in
reduction gear a result of a near miss bomb explosion. The
#3 main motor again had broken brush casualties. When operating
in areas with high water induction temperatures the brushes
spark badly and the motor hogs the load. Immediate inspection
reveals that all brushes in one brush rigging are worn down
considerably more than others. Also the riveted connection
to a shunt field coil is burned and loose. There is only one
engine to overhaul and balance of refit work is largely routine.

5. The Squadron Commander sincerely congratulates
the Commanding Officer, officers and crew upon the completion
of another successful patrol under difficult conditions and
on the damage inflicted on the enemy.

Subject: U.S.S. SAIDLANCE (SS331). Report of Third War Patrol
[UNCLEAR: comment on...]

1. The Third War Patrol of SAIDLANCE was conducted in the
CELEBES SEA. One AK was sunk and another damaged in the FLORES SEA
enroute to the assigned area.

2. SAIDLANCE encountered heavy and effective anti-submar-
ine plane activity in the clear and smooth water of the CELEBES SEA.
Two promising attacks were frustrated by bombs from planes. On the
second occasion a particularly careful approach was conducted at one
hundred feet. Only one observation at 5,500 yards range was made
after the original sighting until time for the final firing bearing.
Two plane bombs exploded under the stern when the submarine was pass-
ing seventy feet on the way up to periscope depth. The port shaft
was put out of commission by this bombing, necessitating a return to
base.

3. Thorough investigation into alignment, main motors, and
reduction gears, during the refit period has failed to reveal the exact
nature of the damage to the port shaft. The shafting is still noisy
and should not be used except in emergency. The trouble appears to
be located in the reduction gears, and as it is beyond the capacity
of local repair facilities, SAIDLANCE is being returned to a Navy
Yard for complete repairs.

4. SAIDLANCE experienced a serious torpedo casualty during
this patrol. In spite of the close bombing mentioned above, the
Commanding Officer continued the attack. He attempted to fire one
Mark 18 torpedo from No. 8 tube about fifteen seconds after the bomb
exploded, but it only moved far enough to trip the starting lever,
and it made a hot run in the tube. This torpedo was apparently over
size or longitudinally deformed, because difficulty had been encoun-
tered in loading it into the tube. This casualty emphasizes the
necessity for carefully fitting all Mark 18 torpedoes into the tor-
pedo tubes prior to departing on patrol. A detailed discussion of

     2000 K Departed lifeguard station for patrol area. The absence of
               anti-submarine measures in this vicinity is surprising. In
               seven days off Tokyo Bay we saw just one patrol boat and
               nothing larger. On several occasions we approached within
               ten miles of Nojima Saki on the surface in broad daylight.
               Although driven down by planes on numerous occasions about
               half the time the planes were our own.

               high speed, target went by, closest range eight thousand
               yards. Target had general size and appearance of a DE. As we
               were off Todo Saki at the time a surface end around would
               have taken us into some mine fields so we broke off the attack.

0155 K         In 500 fathoms of water south of Erimo Saki ran into something
               metallic that sounded like a chain or cable. It apparently
               wrapped around the sound head being used as TDM and that could
               not be raised. By rotating in the opposite direction and back-
               ing down the sound head was finally freed.

1140 K Sighted smoke. Closed and determined it to be a small steamer
and started an end around.
1305 K Contacted TORSK and passed what information we had. Tried to
cross over and attack from flank away from TORSK. After cross-
ing over and closing until tops were sighted from bridge, at
1425 dove and continued in submerged. Target was not steadied
on a course but wandering around aimlessly.
1610 K Target reversed course so surfaced and relocated target.
Decided the only way to take care of him was to get between
him and shore, let him see me on the surface and drive him
torward the TORSK. As we approached I could see he was a steam
trawler or picket boat and not a torpedo target. However
upon seeing us he acted very coy and not at all frightened.
He made frequent course changes but did not attempt to run
away. This looked peculiar to me so I dove and attempted to
close submerged to get a look at his armament before the
fireworks started. After diving I lost him again and upon
surfacing did not relocate him.

  0820  Pilot came aboard,
  0845  Moored berth Sail 7, Midway Island.

(c) WEATHER:
In areas ONE, TWO and THREE skies were completely overcast 45% of the time, about 5/10 overcast 39% and clear 16%. There were only two stormy days and nights. Early mornings and fore-moons were in general characterized by surface fogs and haze and glassy water. These conditions were to be expected from comments of previous reports.

(d) TIDAL INFORMATION:
In the region just east of Myako Shima in the Nampo Shotc group there appears to be a constant southerly set of about 1.5 knots. An north-easterly set would normally be expected here. Otherwise throughout the Nampo Shotc region currents are generally as listed in Sailing Directions.
A 1 knot easterly set was encountered at all times along the coast of Honshu from Kinkasan Island to Hokkaido.

(e) NAVIGATIONAL AIDS:
East Saki Light at the eastern entrance to Tsugaru Strait was observed to be burning with normal characteristics and at full power during the early morning of 5/2/45. The northeast coast of Honshu and south coast of Hokkaido are rather difficult to use for accurately determining a position, due to the super-abundance of rocks, none of them especially prominent.

(F) SHIP CONTACTS: (Continued)

          NOTE: *all sound contacts were picked up in 100 fathoms of
          water at submarine speed of 2.5 knots and 100 foot
          keel depth. Except in the cases of pinging, screws
          were the first thing heard. JP and JK were always in
          use at the same time. Relative bearings were from
          5° on the bows to 45° abaft the beams. JP was gener-
          ally used on 3000 cycles. Due to noisy bow plane tilt-
          ing motor, the 500 cycles position is practically
          useless. JK was used with a 17.5 kc setting.

(G) AIRCRAFT CONTACTS:

          No new planes or trends encountered. Off Nojima Saki at
          night several times planes, which I am positive were our own,
          made radar runs on us even though we had IFF turned on.

(H) ATTACK DATA:

          See torpedo attack forms - pages 18 and 19.

(I) MINES:

          Sighted seven drifting mines spread overhalf of the
          Pacific Ocean. No minelaying operations observed.

(J) ANTISUBMARINE MEASURES AND EVASION TACTICS:

          Antisubmarine measures encountered were very light. One
          night off Kinkasan two patrol boats, at least one of which
          was positively radar equipped, attempted to force us into a
          mine field but the maneuver was not very successful since
          their maximum speed seemed to be fifteen knots.

(K) MAJOR DEFECTS AND DAMAGE:

          On April 7, 1945, enroute from Pearl Harbor to Guam, upon
          surfacing from a routine trim dive, it was found that the bow
          planes would not rig in. In the forward torpedo room it was
          observed that the hydraulic interlock valve was not function-
          ing, for the mechanical indicator and the vertical drive shaft
          kept rotating as long as the system was lined up for "Rigging
          in" or "Rigging out". A topside inspection showed the trouble
          to be the failure of the bronze coupling just aft of the rig-
          ging bull gears (pc Y3 732-201 Buships Draw. 544557 ALT 1).
          Because the hydraulic interlock was not operating properly,
          600# hydraulic pressure was still driving the bull gears when
          the gears were against the mechanical stop. This caused the
          key locking the coupling to the horizontal drive shaft (Pc Y3
          732-201 Buships Draw. 544557 ALT 1) to roll out of its keyway
          and burst the cast bronze coupling. Efforts to rig the planes
          in with chain hoists, etc. were not successful. We returned
          to Pearl for repairs.
          At Pearl, a new coupling and new horizontal drive shaft
          were manufactured and installed, and interlock mechanism was
          set.

(K) MAJOR DEFECTS AND DAMAGE: (Continued)

On April 10, 1945, departed Pearl for Guam. On April 17,
1945, upon surfacing from a routine dive, our trouble of 10 days
previous was repeated, the same piece of the forward coupling
being the one to fail under the stress. The bow planes were
rigged in by using chain hoists and cables linked to the pad-
eyes which were welded on the outboard edge of the outboard
edge of the planes at Pearl for just this emergency. Continued
on to Guam.
At Guam, all the bronze couplings were replaced by copper
nickel steel couplings, thus greatly increasing the strength
of these members. Attention was then concentrated on the source
of the trouble, the hydraulic rigging interlock valve, the
following being accomplished: made thorough inspection and made
extreme adjustments in which it was found that the valve could
be made to operate properly in "Rigging in" but not in "Rigging
out". The interlock valve was dismantled. The interlock piston
(Pc B3 Buships Draw. 544560) was set up in a lathe and the
whole rigging out spool was cut off. A brass bushing was man-
ufactured to fit over the piston to take the place of the old
spool which was brass weld. The new bushing was 3/16" longer
than the old spool, thus, in effect increasing the stroke of
piston in "Rigging out" while not affecting "Rigging in".
This made the distance from the leading edge of the spool
lapped area to the end of the piston 5-7/16" instead of the
original 5-5/8". This bushing was silver brazed on the piston,
then ground to the approximate size and lapped in to the valve
body (Pc A3 Buships Draw. 544560). The valve was reassembled,
reinstalled, and adjusted until the valve cut off the oil
supply before the planes hit the mechanical stop, both rigging
in and rigging out. We have had no further bow plane trouble.
Between Pearl and Guam No. 4 main engine started making
dark smoke and using lubricating oil. Tests showed that three
cylinders had high temperatures and low compression. Visual
inspection showed that these three and other pistons were very
badly carbonized. The rings were pulled and it was found that
the rings were not only bad but improperly installed. The rings
were not staggered but all the gaps were in line. This resulted
in complete re-ringing of the engine. New spares were drawn at
Guam and the engine has performed satisfactory for the complete
run. This engine had been overhauled at Navy Yard, Mare Island.
The last week in May the same trouble as above developed
in one cylinder of No. 1 main engine. On 1 June when this engine
was carrying the battery charge, the exhaust temperature rose
rapidly and a pressure built up in the crank case. The engine
was immediately secured and this piston pulled. It was found
that one ring had broken. This ring caught in the exhaust post
breaking the remaining rings and stripping sections of the ring
lands. Due to cylinder heat, metal pitted off piston and welded
on cylinder liner. The engine was left out of commission and
will be overhauled during refit.

(1) RADIO:

TBL - The limited range of voltage regulation will not
handle the highest battery voltage. It is not possible to
transmit from approximately one hour before the finishing
rate until the end of the battery charge.
The "Spot Type" antennae have proved satisfactory. The
two flat antennae are not quite as good as the old arrange-
ment. Reception on the whip antenna is about the same as on
the old ones in a flat sea; but since waves do not hit it,
there is no fading in a rough sea. This also holds for trans-
mitting at the lower frequencies. At frequencies above 8,000
kc the shorter vertical whip is much better than the old
flat antennae were.
The TBL speech input proved satisfactory during training
but was not used while on patrol.
VHF - Exchanged calls with one friendly plane and comm-
unicated with friendly submarines. Reception from other subs
good inside 10,000 yards. They indicate our signal is weak,
outside 15,000 yards for this type
This equipment is useless
work.
SCR-610 - Used one time for communication with friendly
submarine at range of 8 miles with very good results.
Communication as a whole were good during this patrol.
Used 9090 and 13655 kcs almost exclusively. 6045 kcs was
useless most of the time due to heavy CW signals, voice and
random noise. Lifeguard frequency 4475 kcs gave only fair
reception in daytime, and very crowded at night, although no
jamming was experienced. Heavy interference was encountered
on certain alternate frequencies, but do not believe it was
jamming.
One Comsubspac serial was missed. It is suggested that
Comsubspac will use serials on important publication changes
such as recognition changes.

(M) RADAR:

SJ and ST - Power fuses to high voltage rectifier
started blowing. When the fuses were renewed the equipment
would be back in good operating condition. Just before the
supply of fuses was exhausted the trouble started staying
on long enough to trouble shoot. The pulse repetition rate
would increase, the voltage decrease and the high volt-
age rectifier current increase 100%. It was then suspected
that C(28) in the transmitter was breaking down. Replacing
this condenser cleared the trouble.
The above casualties resulted in very little time out
of commission and the operation of the equipment was satis-
factory.
The one time the ST was used submerged, a range of 5,000
yards was gotten on a patrol boat. 10 feet of periscope had to
be exposed. When SJ interference, which could not be identi-
fied, was picked up the SJ was secured and the ST used for
search. When the SJ was keyed 30 minutes later, the interfer-
ence was gone. No contact was made.

SD - The performance of this equipment was exceptional
until the mast was left in the raised position on a dive at
standard speed. This broke a jumper between one line going
up the mast and the lead through the pressure proof base.
This was repaired but the equipment will not tune properly.
By the end of the patrol we are operating with a maximum of
6 mils plate current and suspect that there is more trouble
in the mast. Ranges vary from 5 to 30 miles on planes and up
to 40 miles on land.
IFF - The BN operates satisfactory, but it is believed
that the BK is triggered by something on board. Anytime it
is on code for which it is set it can be picked up on the
APR. Both sets act the same. We have had no occasion for
using the IFF equipment with the SJ.
APR-SPA - SPA sweeps erratic - R201 burnt and T201 hot
and cooking. Replacing R201 and 2X2 cleared trouble for a
while. T201 checked good but soon burned up. Replaced T201
and equipment operated almost continuously for 40 days with
no trouble.

(N) SONAR GEAR AND SOUND CONDITIONS:
JK-QC - JK cable leading to head sheared off by lower-
ing head on it. Splice made and normal operation resumed. Shaft
screwed 2½ turns out of upper collar assembly. The locking
set screws worked loose and the shaft backed out during
training of head. With the head in the raised position the
shaft was clamped and the collar screwed back on. It was
found to tighten up with the JK 0° scribe lined up with
Zero on the WC azimuth scale and was locked in this position.
It was then determined that the JK, instead of being 180°
out in bearing was reading 10° high. This led to much con-
fusion as to bearing, but the ranges for picking up sampans
and patrol boats was 3000 to 5000 yards. The ship that was
sunk however was not picked up by the JK until it had closed
to less than 3000 yards.

(N) SONAR GEAR AND SOUND CONDITIONS: (Continued)

                     QB - The slip ring modification proved satisfactory
                     with only minor casualties to the braid resulting from
                     continuous rotation of the head. The TDM was manned all
                     the time on the surface at 1/3 speed. 8 rolls of recorder
                     paper were used. The only contacts positively identified
                     were submarines with which we were making a rendezvous.
                     These were picked up at ranges of from 700 to 2500 yards.
                     The only casualty to the TDM was the shearing of the fly-
                     back stop pin.
                     FATHOMETER - This equipment saw lots of use this run
                     and gave good results with no casualties.
                     JP - This equipment constantly picked up sampans and
                     patrol boats at from 5,000 to 10,000 yards. This is the
                     first run that the JP has picked up target at greater range
                     than the JK.
                     Sound conditions at 42-15 N, 142-30 E and 42-50 N,
                     144-17 E were good for the month of May. In the warmer
                     water at 38-45 N, 141-50 E the ranges were 30 to 40 per-
                     cent less on both the JK and JP.

(O) DENSITY LAYERS:

                     No specific comments can be made. There were gradients
                     90% of the dives, but there were only a few definite layers.

(P) HEALTH, FOOD, AND HABITABILITY:

                     The food received at Pearl this time was the worst I've
                     seen since the beginning of the war. The majority of the
                     potatoes were too rotten to eat and the meat was equally bad.
                     When meat loaf is too tough to eat, that's a new low. With
                     this exception the food was good and the cooks and baker did
                     an excellent job.
                     The booster blower and additional air conditioning for-
                     ward certainly makes a world of difference in the habitability
                     of the boat.
                     Health was in general excellent. One man was on light
                     duty for two weeks with a lacerated hand and one man accident-
                     ally suffered the loss of two phalanges of his right index
                     finger. He was transferred to another boat returning to port.
                     Most of the crew do not take vitamin pills as they find the
                     odor offensive.

On 9 May 1945, a vessel similar to a DE could not be closed after
an hour and forty minute approach at high speed submerged.

On 14 May 1945, while patrolling on the surface, a small unescort-
ed freighter was sighted through the high periscope. SANDLANCE
gained position ahead and conducted a submerged attack. Four
electric torpedoes, set at 5 feet, were fired from 1900 yards with
small gyro angles. One hit was obtained and target had disappeared
three minutes later.

Another small freighter was sighted on 24 May, but could not be
closed.

           139°28'0 E, at
0200 (I) a very bright green meteoritic stream across the sky low
           ahead. Immediately we saw green Very stars bearing 325°T,
           which was about TORO's bearing. Having seen nothing more
           of our red flare, we closed the green Very stars and
           upon contacting TORO found it was she firing the stars.
           She had not seen red flare, but had glimpsed green met-
           eorite and interpreted it as being possibly someone down.
           Exchange of information led us to believe we had both seen
           "shooting stars"; especially since there had been no word
           of anyone in trouble in this area.

             every 15 minutes. Our fuel supply is dwindling, and
             this is one way to make it stretch; as we've had no

2230 (I) Sent SAHD LANCE FIRST to SubPac informing him of results of search to date.

If survivor carried out directions given him when boat was dropped he must have been driven inside 100-fathom curve just southwest of Bungo Suido. However, having a power boat, he might have headed for open water to the southeast of his ditching position. In any event it would have been necessary for him to head into the sea commencing this morning or be swamped into the sea he could make little or no heads ay.

4 August (continued)
1540 (I) Sank light grey, slightly rust streaked belly tank at
          31°35'0 N, 133°02'0 E.

          We are just inside National League territory, but want
          to complete our search along this edge of Air-Surface
          Zone. By tomorrow afternoon we will have searched all
          of our area and part of DRAGONET's except inside 100
          fathom curve. Up to now we have thoroughly covered 1700
          square miles; 1400 of which was during daylight. Still
          no lifeboat.

1800 (I) Sighted floating mine at 31°40'0 N, 133°06'0 E. Shot
          at it for one-half hour with carbines and .50 cal.

1820 (I) Exchanged calls with PIPEFISH. She took over mine dis-
          posal detail and sank mine. Maybe our shots contribu-
          ted some towards the sinking, but I'm doubtful.

2030 (I) Converted 4 and 5 fuel ballast tanks to main ballast.

2253 (I) Dove for TDM contact. No contact after submerging.

2339 (I) Surfaced after flushing out 4 and 5 ballast tanks.

5 August
0105 (I) SJ contact on target giving SJ interference at 14,000
          yards. Exchanged recognition but no calls. Probably
          PIPEFISH.

0330 (I) SJ contact and SJ interference at 12,500 yards. Were
          not successful in exchanging recognition or calls.
          There are three other boats in this general vicinity.

0443 (I) Dove.

0535 (I) Surfaced. Continued search.

0715 (I) Dove. Unsighted, unidentified SD contact in to six miles.

0850 (I) Surfaced. Commenced renewing cracked liner in #2 main
          engine.

1115 (I) Sank what appeared to be an aircraft mooring buoy or net
          float at 31°45'0 N, 132°39'0 E. It was about the same
          size as a mine and had a padeye on its top. Three Pri-
          vateers were in sight at this time, none of them showing
          IFF.

1200 (I) Position: 31°47'0 N, 132°39'0 E.
1345 (I) Sighted what appeared to be a belly or a wing tank, but
not as highly streamlined as yesterday's. For half its
length it was cylindrical with a round end. The other
half length was a truncated cone ending with about a
six -inch circular section having what appeared to be a
piece of tubing sticking out of this small end. Posi-
tion: 31°40'0 N, 132°25'0 E.
1400 (I) Held Church Services.
1430 (I) Sighted another of the same sort of tank.
1700 (I) Quartermaster at high per.scope, OOD, JOOD, and one
lookout sighted periscope in our wake about 2500 yards
astern. It was visible for about five minutes. It was
grey in color and was about two feet exposed. I thought
I saw it momentarily after reaching the bridge, but
couldn't be certain. Position 31°14'0 N, 132°09'0 E.
We were steering by course clock at the time, making 2
engine speed. Believe if it were merely a floating
object it would have been picked up ahead earlier, as
it was in our wake when spotted.
2150 (I) Dove. Unidentified plane contact at 4 miles. The great
majority of these people don't seem to use their IFF
or VHF. I would suspect our BN, except we do get
occasional return on it.
2220 (I) Surfaced. Have searched entire area, 2500 square miles;
no survivor.

6 August
0448 (I) Dove.
0536 (I) Surfaced. Sent SAND LANCE SECOND to SubsPac.
0915 (I) Received lifeguard assignment for today. Headed for
station. From now until 1500 sighted numerous oil
drums and ammunition cans. Some of the oil drums ap-
peared to be full and were awash.
1115 (I) Air cover arrived, but not that assigned to us.

6 August (continued)
1340 (I) In practically continuous heavy rain and wind squalls.
          Visibility 4000 yards. Air cover departed.

1350 (I) Passed belly tank. It was black and looked new.

1400 (I) Could hear our assigned air cover talking among them-
          selves but could not contact it. Had no SD contact
          with it either. We heard POMFRET and her cover talking
          200 miles away on 4475 Kc.

2000 (I) Converted #3 fuel ballast tank to main ballast.

7 August
0442 (I) Dove. Will remain submerged at SD depth long enough to
          lift and replace upper crankshaft of #2 engine to re-
          place liner in #2 unit. Keeping constant watch on ASR
          frequency, Fox frequency and 4475 Kc. Using SD mast as
          antenna.

          Sighted flights of B-29's throughout morning.

1200 (I) Position: 31°23'0 N, 131°38'0 E.

1215 (I) Surfaced. Patrolled lifeguard station.

2136 (I) Submerged for TDM contact. No sound heard after diving.
          Trace is dead ahead. This has occurred several times.
          Will renew braids to see if the trace is caused locally.

2222 (I) Surfaced.

0434 (I) Dove.

0745 (I) Surfaced.

1000 (I) B-17, PBM and 8 Mustangs circled our position on their
          way north asking if we had anything for them. They said
          they would stop on their way back.

1200 (I) Position: 30°48'0 N, 131°51'5 E.

          Passed four belly or wing tanks floating end-up during
          afternoon. Sank one of them.

9 August
0436 (I) Jove.
0505 (I) Surfaced. Noticed air bubbles just before surfacing.
           Secured all main ballast blows - no change. We may have
           leaking bottles in #2 A or C ballast tanks or we may
           have leaking impulse bottles. #5 impulse drops 50 pounds
           during a 4-hour period.

           About 100 bombers - B-17's, B-24's and B-25's passed
           over headed north during morning. Also some fighter groups
           came over.

1200 (I) Position: 31°14'0 N, 131°38'0 E.

1210 (I) Received word of Russia's entry into the War.

1215 (I) Planes started passing over on return trip.

1300 (I) Saw 6 B-25's flying along coast line. Just after they
           passed, smoke arose from vicinity of Shimokata at 31°33 N,
           131 23 E.

1320 (I) Sighted yellow, rubber boat at 31°03 N, 131°38 E.
           Closed it and recovered it. It was only half inflated.
           The CO₂ bottle was only partially discharged. Two pockets
           contained pliers, pocket knife, scissors, patching kit,
           wooden plugs, hose clamps and white line. Boat had evi-
           dently been in the water for an appreciable length of
           time as several small clusters of barnacles were growing
           on underside. Several fish of minnow size and small crabs
           were in pockets. Boat was made by Goodyear for the Army.
           It was Type 3 ? AE. The CO₂ bottle was serial C-1565 for
           type A-3 boat. Penciled on the reenforcing pad around
           inflating connection was "OK 58472". Stamped on a reen-
           forcing pad just below inflating connection was 3581. All
           other markings except instructions were illegible.

1345 (I) VHF receiver picked up message from some plane that it
           was afire. We could raise no one. PBM near us had no word
           of it. Nothing else heard on VHF.

1400 (I) Passed floating 5-inch powder can.

1515 (I) New column of smoke appeared where other smoke is still
           rising. Maybe an explosion.

0346 (1) Dove.

0557 (1) Surfaced.

0630 (1) Sank what appeared to be a small tank of about ten (10) gallons capacity having a heavy steel plate bottom and what appeared to be two (2) gages on top. Tried to sink a belly tank nearby, but Caroline fire would not penetrate it. Position 30°50' N, 131°51' E.

0730 (1) Picked up one-man rubber liferaft at 30°50' N, 131°41' E. It was only partially inflated and floating vertically. It was made by Firestone Tire and Rubber Co. The only number other than contract number on it was 6502-1. The seal of the CO2 bottle was broken and the bottle was empty. It was for but specifications All-72. The seat pack containing emergency equipment was trailing over the side and was not touched and consisted of: signaling mirror, drinking water kit, wood and plug, scissors, patching kit, water dye, and first aid kit. The inside of the first aid kit was perfectly dry. Believe this to be an army raft, as the first aid kit was an army kit.

*Considerable debris is floating in this vicinity, along with what appears to be old bunker oil.

1200 (I) Position: 31°03' N, 131°52' E.

Throughout day there was constantly Hotsan in sight. At the same time there was an unusually strong set to the Kuroshio, perhaps all of this stuff is coming from the Northern Ryukyu's.

1845 (I) Passed small boat burned to the waterline and awash.
It was about 35 feet in length and of typical sampan
lines. The after part was still intact and under water,
but the forward part was burned to the knee with the
stem sticking up in the air. The bilges were separated
into compartments about 2 feet square and were painted
white. No motive power was in evidence, so it must have
been a sailboat. The remains were sprinkled with what
appeared to be bullet holes of about .50 caliber size.
No markings or material were found. Position 31°20 N,

2215 (I)  After running down target's bearing for about five miles,
suddenly picked up a contact at 3100 yards, 10 on the
port bow. Avoided and tracked on 270° at about 2 knots.
Lost contact at 1,500 yards. Never sighted anything nor
regarding contact. We had many short range "whatsit" con-
tacts throughout the evening, but this was the first
one that tracked at all constantly. Could be a Jap
cub releasing a decoy balloon and diving?
2220 (I)  Very bright and sudden flash, concentrated in a small
area to north at about 5° position angle.

15 August (I)
0015 (I)  Search plane said he had a contact at 7 miles. We told

CONFIDENTIAL

(C) WEATHER:
Weather in general was excellent except for one
period between 1 August and 3 August 1945. Unfortunately
this came in the middle of a 5-day search for a reported
aviator in a lifeboat and greatly reduced the effective-
ness of the search on 1 August. On 2 August the search
had to be abandoned in order to head into the heavy seas,
and on 3 August the day was spent submerged to avoid very
heavy seas and clear up numerous electrical grounds
throughout the boat. Wind and seas came steadily from
the southeast and averaged force 6 or force 7 during this
period.

(D) TIDAL INFORMATION:
Currents in the vicinity of the Sofu Gan and in the
area 30 miles east of Tanega Shima agreed in general
with Hydrographic Office publications for this time of
the year. The Japan Stream in the vicinity of 31-00 N
and 131°-45 E had a strong, steady set of 2 to 3 knots
on 038°T about 4 days out of 5. Approximately every 5th
day it became variable and unpredictable.

(E) NAVIGATIONAL AIDS:
No navigational aids were encountered. Toi Misaki
Light (lat 31-22 N, Long 131-21 E) was not observed to
be burning when this point was observed at night at dis-
tances of 12 to 15 miles.

(F) SHIP CONTACTS:
None - other than our own submarines plus one radar
contact which disappeared.

(G) AIRCRAFT CONTACTS:
In spite of the fact that we were always from only
10 to 50 miles from SE Kyushu, we had only two (2) prob-
ably enemy plane contacts. One was at dusk when we had
three (3) Jap radars on us and were 12 miles from the
beach. One was at night at four (4) miles on SD and sat-
uration pip of 150 m.c. on APR. Neither contact was sighted.

Our own planes were more trouble.

CONFIDENTIAL
(H) ATTACK DATA:

No attacks.

(I) MINES:

Saw only three (3) floating mines. Exploded one; lost
one close aboard at night; PIPEFISH sank third.

No mining or minesweeping activity observed.

(J) ANTISUBMARINE MEASURES AND EVASION TACTICS:

All contacts, other than planes and friendly submarines,
were probable periscope contacts. Avoided them on su rface at
flank speed.

The only anti-submarine measures encountered were prob-
able enemy submarines. The occasion on the evening of 14
August may possibly have been an enemy sub putting out a
decoy balloon then diving and lying in wait for us to close
the contact - which we did.

(K) MAJOR DEFECTS AND DAMAGE:

HULL & MACHINERY

1. No. 2 Main Engine - On 5 August, 965 engine hours
after Navy Yard, Mare Island overhaul, both the inner and
outer walls of No. 2 cylinder liner cracked. The liner was
changed. On 14 August, 1039 engine hours after Navy Yard,
Mare Island overhaul, the outer wall of No. 3 cylinder
liner cracked. No water showed inside the liner under pres-
sure test. The liner has not been changed and the engine is
used when necessary.

2. No. 1 Main Engine - On 15 August, 132 engine hours
after Midway refit, this engine began tripping itself off.
A part in the overspeed trip was found badly worn. It was
filed back into shape and the engine put back into commis-
sion.

3. No. 3 Main Engine - On 21 August, 542 engine hours
after Midway refit, the outer wall of No. 6 cylinder liner
cracked. This liner was not changed and the engine is still
in operation. Each of these liners has cracked just above
or below an adapter. It is believed that the copper gasket
sealing the adapter at the inner wall is leaking enough to
blow the water out of the liner at this point; causing local
heating which results in the cracking of the liner wall. All
the copper gaskets will be annealed during refit and tests
conducted to determine whether they hold.

HULL & MACHINERY (Continued)

4. No. 2 Main Generator - On 21 July, the joint be-
tween the flexible connection to the positive brush rig-
ging and the bus leading out of the generator overheated.
The joint was broken, dressed down and remade. This sec-
tion of bus will have to be renewed during refit.

5. Auxiliary Generator - On 3 August, after a siege
of heavy seas the auxiliary generator armature megged
zero to ground. The reading was brought up by heating and
drying.

(L) RADIO:
9090, 13655 and 16730 Kcs were the most usable fre-
quencies for copying SubFox. Some interference was en-
countered but it did not interrupt the schedules. Missed
serial twenty five and have no record of this serial be-
ing run the following night. Sent four messages to Com-
subspac using 8470 Kcs and 12705 Kcs. Two of these were
sent on 8470 Kcs using the whip antennae, two on 12,705
using the port wing antennae. On night of August 5th we
had trouble receiving radio Guam on 8470 or 12705.

Lifeguard communications were carried out without
difficulty except for having to use the APR receiver for
140.58 Mc reception. VHF transmitter functioned properly
at all times. All attempts to repair receiver section VHF
failed. The APR-VHF combination proved to be satisfactory.
All lifeguard-ASR frequencies were well jammed by voice or
pure CW transmissions. Often heard Japs using 4475 Kcs,
voice. Had no occasion to use type DU-1 RD/F loop. With
exception of VHF receiver, suffered no material casualties.

(M) RADAR:
SJ - ST - This equipment was in poor condition at
the beginning of the run. Submarines were picked up at
9000 yards and 3000 foot land at 60,000 yards. After two
weeks of constant work on it, without putting it out of
commission, it was picking up submarines at 15,000 yards
and 9000 foot land at 100,000 yards. It operated satisfac-
torily for the remainder of the run without casualty.

SD - This equipment was satisfactory for the complete
run. High flying B-29's have been tracked in from 75 miles
and the minimum range was a contact at 5 miles which the
SJ picked up first.

(M) (continued)

IFF - This equipment operated without casualty. We
tried operating the BN in a stand-by condition and keying
it once a minute when the SD was keyed. It was believed
that the equipment will not stand continuous operation,
so this method was secured.

(N) SONAR GEAR AND SOUND CONDITIONS:

On 24 July at 29 N, 136-05 E the JP-1 picked up a
submarine on the surface at 15,000 yards. On 17 August
at 29-36 N, 134-00 E the JP-1 picked up another submarine
on the surface at 6000 yards. The JK picked this one up
at 3000 yards. No other sound contacts were identified.

The TDM was a constant source of trouble. The type
CAN 55171 Recorder, the slip ring braids, the flyback
micro switch, and the QB shaft will not stand continuous
operation for the duration of a patrol. The rest of the
WCA stack and the JP-1 operated without casualties.

(O) DENSITY LAYERS:

Density layers of any importance were the exception
rather than the rule on this patrol. No positive gradients
were encountered. The only gradients worth mentioning are
listed as follows:

Date Lat. Long. Gradient Between depths
7/19/45 31-20N 139-50E -4° 80-120
7/22/45 29-30N 136-00E -5° 100-130
7/23/45 29-30N 136-10E -6° 80-120
7/25/45 29-31N 134-37E -10° 80-140
7/26/45 29-23N 137-40E -8° 90-140
7/29/45 31-00N 131-30E -13° 100-240
8/4/45 31-32N 133-00E -8° 120-140

(P) HEALTH, FOOD, AND HABITABILITY:

Health was excellent. Only two (2) sick days were
lost; due to Migraine headaches.

Food was excellent in variety and well prepared.
Our baker is a professional.

Habitability was excellent; due mainly to mild
weather and continuous surface running.

                          The high state of morale that has come to be expected
                     on this boat, continued throughout this very uneventful
                     patrol. The performance of the men and officers, both sea-
                     soned and new, has been excellent. The crew replacements
                     utilized from the relief crew of Submarine Division 321
                     have been above the average we have encountered. It appears
                     at this time that those of the replacements who were un-
                     qualified will be qualified when we reach port.

                          We have our leading auxiliaryman hold school every
                     day in the crew's mess, then the officers qualifying take
                     the students through the boat. After the course of instruc-
                     tion has been completed, the qualified officers take the
                     students through the boat to qualify them.

(U) COMMUNICATIONS, RADAR, AND SONAR COUNTERMEASURES:

Ineffective but constant jamming was encountered
on all frequencies. Heavy jamming seemed to sweep
across 7945 Kcs at intervals of every minute or two
minutes. This type jamming was noticed to be more
effective on 30 July than at any other time.

Radar - No remarks.

Sonar - No remarks.

APR - As a general rule, the APR contacts could
be identified as Jap land based radars. The IFF gear
of friendly planes was easily identified and the oper-
ators usually knew in advance when there would be an
SD contact. Two notable exceptions were contacts at
153/1000/13 each followed by an unidentified SD contact
closing in causing us to dive.

(V) REMARKS:

None.

1. The fifth war patrol of U.S.S. SANDLANCE under
the command of Lieutenant Commander J.G. GLAES was conducted
off the South Coast of HONSHU and the Southeastern Coast of
KYUSHU. This patrol was of fifty-six (56) days duration,
twenty-nine (29) of which were spent on station.

2. The primary mission of this patrol was life guard
duty. No opportunity was afforded SANDLANCE to effect rescue
of aviation personnel, although she conducted a thorough search
for one downed aviator during the period 31 July to 5 August.
The plane which reported itself afire on 9 August apparently
made its base.

3. SANDLANCE reported very little anti-submarine acti-
vity. Only two probable enemy planes were encountered. Several
possible TDM contacts were made but were not definite torpedo
contacts. A possible visual contact on an enemy periscope was
made on 5 August, and possible radar contact on a Japanese sub-
marine on 14 August. This target disappeared indicating that
it may have submerged.

4. On 16 August SANDLANCE departed station as a result
of the cessation of hostilities. It is regretted that SANDLANCE
had no opportunity to add to the damage she has already inflicted
on the enemy, during this, her last patrol of World War II.

of 3 June 1944.

Enclosure: (A) Copy of reference (a) with enclosure (A)
thereto.
(B) Copy of reference (b).

1. Reference (a) was received at a time when the
U.S.S. SANDLANCE was enroute to Fremantle, Australia, after
completion of a patrol in the vicinity of the Marianas. The
SANDLANCE was directed to submit report by despatch, followed
by letter, giving any information concerning identifying marks
which might establish the identity of the ship sunk by her on
3 March 1944. The despatch report provided the SANDLANCE
contained substantially the same information as that contained
in the letter report which is forwarded herewith as enclosure
(B).

2. Prior to departure on patrol the SANDLANCE was
furnished a copy of C.N.O. Intelligence Report, Serial FT-88-43,
Monograph Index Guide No. 505-100 dated 29 December 1943, which
contains full information of routes followed and identification
marks carried by Soviet merchantmen. Commander Task Force Seven-
teen Operation Order No. 51-44, which ordered the SANDLANCE
patrol, contained the following: "Do not attack Russian Shipping."

3. The SANDLANCE was given contact information of
an enemy convoy which indicated the convoy would probably pass
northward through Yetorofu Strait on March 2nd. It was this
convoy which the SANDLANCE attacked at 0020 (King) on March 3rd
in position which corresponded closely to the predicted position
based on the contact report. This attack resulted in one [UNCLEAR: word]

ship sunk and one damaged. A subsequent attack was made at 0745
(King) on 3 March on a ship which was believed to have been the
one previously damaged. This attack resulted in three hits and
the target sank in twenty minutes.

3. A study of the SANDLANCE patrol report indicates
some confusion as to whether the attack at 0745 (King) actually
took place on March 3rd or March 4th. However, the date of the
attack is definitely fixed as March 3rd by the fact that at 2200
GCT on 2 March (0800 King 3 March) the SANDLANCE sent a despatch
to Commander Submarine Force, Pacific Fleet, reporting that he
had sunk two ships of a convoy.

4. The Commanding Officer, in reference (b), states
that during the prolonged approach, in both darkness and daylight,
prior to the attack at 0745 (King), the SANDLANCE had ample
opportunity to observe the target, and that she was carrying
neither the illumination nor the side markings required to be
carried by Soviet merchantmen.

5. It is impossible to determine with any exactitude
whether or not the ship sunk by the SANDLANCE on the morning of
3 March was the ill-fated BELORUSSIA. If it was the BELORUSSIA,
it is believed that the sinking was caused by a most unfortunate
combination of the following circumstances:

(a) She was contacted in a damaged condition in almost the
exact position where a damaged enemy ship was expected
to be found.

(b) The position of contact was far removed from the normal
routes of Soviet merchant shipping.

(c) She carried neither the illumination nor distinctive
side markings required of Soviet merchantmen in the
Okhotsk Sea.

Subject: Sinking of Merchant Vessel on 4 March 1944.

1. This vessel conducted an attack, during the night
of 3 March 1944, on two merchant vessels and one escort sinking
one merchant vessel and damaging the other. These ships came
through Etorofu Strait on the course and speed and at the approx-
imate time predicted by information previously furnished us.

2. Subsequent depth charging forced us down and
consequently lost contact with the damaged ship. Upon surfacing
we plotted the track using the same course and one knot reduction
in speed and four hours later made contact where expected with a
target on the correct course but using a knot less speed. It was
still dark and a radar attack was attempted. After two hours,
having an attack position not obtained, the target stopped so we
waited for daylight. The attack was completed, submerged after
daylight, and the target was sunk.

3. The prolonged attack enabled me to closely observe
this ship both in darkness and in daylight. The ship was completely
darkened during darkness and flew no colors nor could any painted
insignia be observed on the sides during daylight.

4. If this ship was not the one damaged previously,
it is a remarkable coincidence and it definitely was not showing
the identification features prescribed for Russian ships in that
vicinity.

each side extending from the muzzle door to a point five feet back.
These grooves were possibly due to two warhead joint screws bearing
on opposite sides. The interior tube wall showed signs of heat in
a circumferential area about two feet wide, located at the bulkhead
between the after trim tank and the after torpedo room. This is
approximately where the torpedo main motor was located. It is be-
lieved that the battery fully discharged through the motor windings
and salt water across terminals causing a concentration of heat at
this point. During the entire period no battery explosions or other
unusual noises were heard. The drop in water level in the tube was
probably due to flooding of the torpedo. The rise in tube pressure
could have been due to discharging of the air in the torpedo high
pressure air bottles, since this air at fifty pounds pressure would
occupy twenty-nine cubic feet. No efforts were made to vent the tube
at the time because of the danger of chlorine and hydrogen gasses.
However, when the tube was later vented after the third attempt, no
unusual odors were noted. Failure of the torpedo to leave the tube
initially could be contributed to any one item or combination of
items such as the tight fit of the torpedo in the tube, ships dive
angle, tube depth or possible unknown bomb damage. Failure of the
torpedo to leave the tube on the second attempt could have been due
to depth and to the tight fit of the torpedo in the tube, which also
could have been accentuated by damage to the torpedo shell around the
motor. Since the tube was not vented off until after the third
attempt, it is very likely that the air in the tube considerably
absorbed each charge of firing impulse air. Sound reported hearing
the torpedo run after firing. This does not seem possible unless the
forward propeller and gear train were somehow allowed to spin freely
at high speed to cause cavitation. The after
propeller was recovered from the torpedo tube; the after
propeller shaft having sheared. How the torpedo warhead detonated is
unknown, unless this explosion was caused when the exploder armed.
However to arm the exploder mechanism in this time interval would
require a mean speed of seventeen knots. If nine hundred pounds
thrust is necessary to drive the torpedo through the water at thirty
knots, it may have been possible for the torpedo to acquire the 160
pound thrust necessary to drive the torpedo through the water at
seventeen knots, since the negative buoyancy of a fully loaded tor-
pedo would approximate 1500 pounds. Another possibility concerning
detonation of the warhead is: is it possible for the warhead to det-
onate if subjected to pressures at great depths and if so, is this
depth less than the possible maximum submerged depth of a submarine?
