Via: The Commander SEVENTY FLEET.

Subject: U.S.S. TAUTOG - Sixth War Patrol - Comment on.

1. The TAUTOG has again shown tenacity in seeking out the enemy. During this patrol the TAUTOG entered comparatively shallow water and planted a minefield of 24 mines which is believed to have damaged a 6,800 ton LANDLORD. The details of this field are being reported in separate correspondence.

2. On the basis of aircraft sightings of a considerable amount of shipping in the harbors of WESTERN NEW GUINEA and the DARDANELLES, TAUTOG was directed on departure A.DON to reconnoiter in the vicinity of ADI ISLAND, KALIANA and SEBAKAR BAY, DUTCH NEW GUINEA, and DOBO in the ADI ISLANDS. Timely information of ships in these harbors inspired the TAUTOG to penetrate SEBAKAR BAY submerged, KALIANA on the surface, and DOBO submerged to within 4 miles of the shore. None of the aircraft reports of sightings could be confirmed. In spite of frequent aircraft reports of activity at DOBO none was noted by TAUTOG nor was the TAUTOG able to confirm from a position 7 miles from shore repeated reports that a seaplane base is in operation at TG. EBALAN in the KAI ISLANDS. The fact that LAGA and LAUJAL on Northeast TILOR appears to have been built up considerably since last reconnoitered in December.

3. The gun attack on 21 March was well planned and it is regrettable that the casualty which resulted in repeated misfires prevented any damage being inflicted on the enemy ship or the two ore plants.

4. Recent information has provided conclusive evidence that one freighter and the DD attacked on 8 April, sank.

U.S. TATTOO

NARRATIVE CONT'd

Submerged.
Sit ted vessel at anchor in port of KMA. Appeared to be about a 1500 to 3000 ton cargo ship, stick masts fore and aft, composite superstructure painted gray. She was riding to tide or current, mean heading 150°T. Charted her position about 500 yards off beach inside 10 fathom curve. Concluded could approach safely to a range of 2000 yards submerged. However, due to enemy's heading a track of 45° was about best that could be attained without danger of grounding. Decided to fire two straight bow shots. Sea was a glassy calm, reflecting bright sunlight. Ship was loading, but no barge or boats were alongside. Steam winch forward was in operation.
At range 2225 yards fired two torpedoes. First torpedo set at 15 foot depth broached after run of 500 yards. Second torpedo appeared to run a few degrees to left. Fired a third torpedo, as felt sure first two would miss. Ship became heavily probably due to rapidly changing density of shallow water. Speeded up and swung ship to reverse course. Heard two explosions. Very dull indicating torpedo run of 1 minute 20 seconds and 1 minute 24 seconds.
Target undamaged. Could see men running on beach. Fired straight stern shot, (range 1500 yards). Could follow this shot clearly by smoke trail. She apparently started straight then curved left and exploded about 100 yards to left of target. Again explosion was very dull by sound, but sent huge column of water into air. We were disgusted and to add to our failure discovered that due to error in communications after room had fired a second torpedo by hand. This was not observed or heard to explode. It is possible that two torpedoes did not explode, and yet sound conditions were such that they might not have been heard. This expenditure of torpedoes with no results at a set-up made us all feel sick. TATTOO ran for deep water taking frequent observations. Expected plane from KMA-DO, not sighted. No retaliation from Japs at KMA.

In 6CLASS SA on course 326°T enroute HANADO to BASILAT STRAIT, speed 11 kts.

1306(-8)
Sighted what appeared to be a cluster of masts bearing 280°T. C/CT to 100°T to observe change of bearings. Being unable to resist object, C/C to 270°, shifting to three engine combination. C/C to 300° not having resighted possible ships. Sighted masts of two ships bearing 156°T. Bearings soon established an easterly course. Vent to full speed to gain an attack position. Sea flat calm, visibility excellent but bad mirage effect on horizon. Officer manned periscope shears to insure that we kept outside of visibility circle of enemy. Took frequent bearings of ships with No. 2 periscope. Throughout morning established course of enemy 060° to 070°T, speed 13+ kts.

1410(-8)
TAUTOG had run better than 80 miles to gain position ahead of target. Had sighted SARGI ISLAND. Enemy headed through passage between NAVIO and SARGI ISLANDS. Submerged for attack and headed for enemy. Soon picked up masts and discovered target was a large freighter escorted by small destroyer of OTORI class. Enemy was frequently zigging and OTORI changed position on bow twice during approach. Glassy sea made exposures extremely brief. Sound conditions were excellent, OTORI was pinching constantly.

1414(-8)
In attack position on port bow of target, but escort was close aboard. Escort now commenced to change to starboard bow and target zigged toward.

1417(-8)
Fired four torpedoes at range of 1200 yards. Target was large, cargo vessel, Stich mast, goal post, composite superstructure, goal post, stick mast. Had failed to swing TAUTOG left fast enough, necessitating 45° gyro angles. Torpedoes set at 20 foot depth failed to hit. Saw men run fore and aft on deck. Ship did not change course. Escort turned toward us. TAUTOG went deep. Hard explosion, torpedoes or depth charges.

2142(-8) Sighted target, range 7000 yards. Tracking soon showed target had changed course to 080° - 090° T. TUNOC 6000 yards off track. Went to full speed sacrificing most favorable firing point for approach whereby bow was kept pointed to enemy exposing least possible silhouette. The value of such approach having been forcibly impressed on TUNOC at TORIO STRIKE patrol. One minute twenty seconds after first torpedo saw green yellow flash center of target. Captain and executive officer thinking target was firing cleared bridge at speed of sound, for on arrival in conning tower heard explosion. TUNOC submerged. Target's score stayed but position established by loud noise of a large pump. Enemy fired gun at intervals. Pump gradually slowed and stayed at 2345, followed by breaking-up noises.

Enemy due for interception. Not having been sighted, C/C to southward believing target had somehow slipped by.
Sighted two sailboats close aboard.
Set course 160°, speed 11 kts. to head for possible interception point of coast TIDARO at dawn. Certain target not proceeding to COTABATO.
Ten miles off SICARO POINT sighted target previously had dead ahead to starboard on parallel course, range about 10000 yards. Target had been hidden in hazy horizon. TAUTOC was between rising sun, obscured by clouds, and darker, but had excellent land background. Decided to run for position ahead and hope target would not sight us, C/C to 140° to parallel coast and went to full speed.
Enemy suddenly swung stern towards us and fired dead gun. Shot fell comfortably short. She then turned to parallel us and opened up with two guns located in forward well deck and stern gun. Radar could not obtain range on target but splashes were ripped, 2000 yards short on our beam. TAUTOC manned 5" and commenced fire. Conduct of enemy now indicates - 20 -

ed that this ship was an extraordinary old merchantman. Her guns (estimated to be 3") were fired in salvo's and splashes showed they were in a defleation with extremely small dispersion in range. She fired about 2 to 3 salvo's for every shot fired by TAUROC whose firing interval varied from 30 seconds to one minute. Enemy made a determined effort to close range, but TAUTOG noting excellent enemy fire control would not permit. TAUROC was firing at maximum range and about ten shots appeared very close with at least one probable hit forward on the castle.

Had fired 42 rounds and range now opened to per-haps 18000 yards. Gun crew had thoroughly enjoyed this whole freea. Ceased fire. Enemy fired about five more salvo's and also ceased. Estimated enemy had fired 200 to 300 rounds, TAUROC had won morale victory.

Enemy masts still in sight on bearing 160° relative. TAUROC now off POLIT. Sighted mast 40° on port bow.

Submerged for approach on new target.

Had been directly ahead of target during approach and brief exposures had failed to identify target as to size. Now about 5° on port bow, range 3700 yards. Recognized enemy as an A/S vessel very similar to a corvette, with a tripod mast forward and excellent barrel lockout platform on top of foremast.

C/C to pull out for 90° stern tube shot. Shortly thereafter heard loud explosion similar to air-craft bomb. Ran-jeriscope up to see target, bow on making high speed. TAUROC went to 250 feet and rigged for depth charge.

Enemy dropped first depth charge, passed astern and dropped next on starboard quarter at 0710. Enemy did not use echo ranging. She made a determined attempt to locate us dropping eight more heavy charges over a period of two and one half hours. No charges were close. TAUROC held to a mean course of 180° to clear area. Enemy searched in circles passing astern and later ahead of us. At 1100 enemy passed directly over TAUROC but did not drop a charge.

Patrolling south of CAPE SAN AUGUSTIN, MIDWAY.

On course 090°T. Sky overcast, rain squalls in various sectors, about 10 miles south of cape. Sighted two ships, one large, one small, in rain squall bearing 115°T. C/C to 300°T. Went to battle stations and attempted to get a range on radar. After changing course unable to sight enemy.

Enemy opened fire. Estimated gun 4" or better, and range about 4000 yards. Submerged, visibility prohibited use of periscope. Picked up high speed scows and larger, slower, propeller in sound gear. High speed scows approached then passed to southward as did larger ship. Picked up scows similar to that of a destroyer making high speed, bearing 135°T. This ship also passed to southward. Concluded ship and one or probably two escorts, (one ahead and one astern), proceeding to DAVAO. A surface chase impossible as unable to attain attack position prior dawn. Scows last heard bearing about 270°T. Surfaced, visibility poor. Set course 053°T, two engine speed 14 kts. and departed from station for Pearl Harbor, T.T.

Sent dispatch to CTF 71. Posit: 07° - 06' N. 127° - 56' E. Distance run - 252.3 miles. Fuel used - 2150 gallons.

Submerged to check trim.
Surfaced. C/S to 14 kts. (two engines).
C/S to 11 kts.
C/C to 066°T.
Sighted one at two ships dead ahead with smaller ship astern. Bright moonlight impossible to approach to within radar range and remain undetected. From estimate of angle on bow 70° to 90° starboard, concluded course about 155°T. Decided to run ahead and make attack at dawn. Periscope approach possible on this night, but without a radar range and with no OC on board chances of successful attack very slight, also had four torpedoes in stern tubes and two in bow tubes. Desired to be sure we were on their track prior to approach to insure a storm tube shot.

Went to full speed and commenced run around taking bearings on smoke after opening range to estimated 16 to 1000 yards.

Posit: 15° - 33° N, 138° - 59° E.
Distance run - 282 miles.

0331(-9) Sighted ship on port bow bearing about 130°T. This ship could not be one of those previously tracked. Increased speed and C/C slowly to right to attempt determine course of new target. Range appeared to be closing. Kept bright look-out for ships previously tracked. On course 305°T at full speed and opened range. Soon losing sight of ship astern. Commenced swing to right in 30° stages. Had observed enemy base course of about 300°T. Resighted enemy bearing 120°T, T.U.TOC on 090°T. Dawn was starting to break and with bright moon-light to west was sure a submerged attack possible. Submerged and commenced approach. Had determined target to be large tanker. Apparently at all times, she was zigging at intervals of 3 to 6 minutes and had always shown us a port track. Stern tube attack impossible. Fired two torpedoes forward, both hit after run of 35 seconds each. Target turned left towards us. T.U.TOC swung left as fast as possible maneuvering for stern tube shot. Fired two torpedoes stern tubes. Bow gun was firing at periscope so torpedo runs were not observed. First torpedo heard to hit. Sound reported screws still going. T.U.TOC went deep and changed course to parallel target. At periscope depth T.U.TOC on port quarter of tanker about 3000 yards range. Speeded up to attempt gain position to fire last two torpedoes on board. She appeared to be stopped. Shortly after sound reported still near screws. Could not believe this was possible. Slowed for observation, sound bearing 20° to right of ship. Swing periscope to sight A/S vessel, overtake type about 1000 yards range. Realized this escort had been with target all this time on her starboard quarter. Sound bearings had been about same as that of tanker until now. Sound had reported two ships previously, but commanding officer had been unable to verify reports. T.U.TOC went deep, turned toward A/S to run astern of stopped

Tracking enemy ships or ships, on various courses and speeds.

Received instructions, ComSubPac to maintain contact with damaged tanker and keep U.S.S. TUNNY informed. Decided but slight chance of successful attack on present contact with two torpedoes aboard. Had determined enemy consisted of one ship and escort or course south east, speed 10 to 12 kts. Bright moonlit, calm sea prohibited surface approach to within even radar range, (9000 yards). Set course to return to tanker at full speed (16 kts.).

Sent dispatch to TUNNY reporting new contact and last position of damaged tanker.

Sighted tops of tanker. Excellent navigation by Lieut.-Comdr., D. ZBRIEHL, jr., had made this possible, involving no search.

Submerged to approach tanker.

Tanker definitely down more by stern than yesterday. Sighted A/S vessel petroling starboard side as before.

Sighted masts of another small vessel astern of tanker.

Sighted two engine petrol sea plane, similar to a PBY.

0127(-9) Determined position due west of tanker, 12 to 18 miles. C/C to 0900T.
0242(-9) Sighted object similar to small boat in water. Sea flat calm, bright moonlight, visibility excellent. Maneuvered to observe object prior approaching same.
0300(-9) Approaching object close aboard, entered large oil slick area with many small objects and debris in water. Object sighted appeared to be wood deck locker about size of large piano box. This position checked with our estimated position of tanker. She had either sunk or been towed away, or got underway with own owner. Believe considerable evidence favored sinking. Since last sighted her angle down by stern was considerable. Perhaps TUNY had scored. Sent to full speed and set course 125°T heading from position to AFR, GUAM.

Time explosion: 35 sec.
Offset: 0
Remarks: Hit

about 4 minutes elapsed between tube ITO. 2 and tube ITO. 7 firing.
Date about 3 from reconstruction of problem. Stern tubes were fired on 40° track because it was believed that target was making an effort to run us down. Target turned right, back to approximately original course after stern tubes were fired. Target fired down gun at periscope as stern tubes were fired. Hit was not observed. So tube hits were seen shortly after explosions. Track position of hits not determined.

9. MAJOR DEFECTS IN THE ENGINE CONT'D

(5) Three main engine piston seizures occurred, (the first in three patrols). One casualty is attributed to personnel error, and two, to dirty fuel oil. The TAUTOG has been in commission for three years and each main engine has about 5000 engine hours which is considerable for a submarine of her age.

(C) Following a deep submersion with excess water in maneuvering room bilges, water was discovered in port main reduction gear sump. It was immediately flushed out and oil renewed. It is believed that no harm was done.

(D) Due to a shorted shunt field coil, auxiliary generator is out of commission.

(E) On deep dives much water accumulates in main induction. Cause or source of this nuisance has not been determined.

(F) A reconditioned JFK sound head did yeoman service this patrol. In this regard the work of the U. S. S. PELIS in a hurried installation is deeply appreciated. Loss of OC head is, however, keenly felt. Two sound heads in operation during an approach or evasion are extremely desirable.

(C) The modification of firing pin striker for 5" gun accomplished during refit period was entirely satisfactory.

10. RUMBLES

No difficulties with radio reception in SOUTH WEST PACIFIC or PACIFIC area were encountered.

Sound conditions in OCEANIC SEA and IORO GULF were excellent except when close to coast. A negative temperature gradient of 6° from surface to 250 feet was experienced off 1.11D.140 on the 8th of June.

— page 54 —
10. RATINGS Cont'd

A small air conditioning unit was installed in coming over during refit period. The combination of this unit and blower in No. 2 periscope well made the coming over habitability good.

The spirit of officers and crew of the T.U.T.O.G. thought considerably dampened by noises remains at a high level.

C/O to south. Enountered frequent heavy rain squalls this night.
Submerged on course 305°T.
Sighted smoke and mast tops of several ships in MALIATAR HORROR. TAUTOC in quite close, about two to three miles off rocfs. Began circling to observe any ship movements.
Rain periodically reducing visibility in various directions. Sighted small freighter bearing 258°T apparently standing northward along rocfs toward MALIATAR PASSAGE. Range 7500 yds. Commenced approaching.
TAUTOC was 2000 yds or less from rocfs, i.e. lighted buoy on Chart 5423. Ship was 3500 yds distant, concluded she must be behind rocfs entering MALIATAR PASS. Our "old friend." the travcler was on port beam with zero angle on bow. Decided shot at target impossible. Sighted at least three medium ships and several smaller ones in harbor. TAUTOC could only turn toward A/S travcler to avoid groundings. Went to 150 feet and passed under travcler. This vessel has a pronounced clipper bow, gun platform appeared white, and a white arming over bridge. At periscope depth. Sound conditions so poor never heard travcler and vice versa. Nor sighted her as torn on reverse course at channel entrance. A wind had whipped up white caps. Four bow tubes had been made ready about 4 minutes before, decided not to fire. Outer doors were closed before going deep and tubes drained. Shortly after outer doors were closed noises were heard in tubes 2 and 3. Tube two had a short run stopped by action of the tail stop. Both torpedoes were gurgling and hot. Tapped. Tube three came aft. Afterbody handle, 7 handhole, and 6 handhole plates were cracked in succession. Hot water, black smoke and chlorine gas issued forth respectively from these plates. Gyro spindle socket was getting red hot and whole aftershock and battery compartment were too hot to touch. Thought of cooling it off in tube but decided to get rid of this annoyance as the safest procedure. Came to course 090°T, and waited for rain squall to observe A/S vessel.

SIGHTING class.
Closest range attained 5800 yds. DD which had been trailing now went alac at starboard bow of target. Target was zigging between courses of 220°T to 270°T.
Sighted URI class type destroyer bearing 040°T, angle on bow 100° starboard, headed for port. Sho had evidently swept area to northward. Target disappeared in rain squall. TAUROC ran west in hopes of resighting or if squall closed in obscuring beach, would surface and chase. Rain did not close in.
Chase impossible, as was not sure what final direction of ship, may have gone south, southwest, or west. Set course 090 to return to harbor on trance.
Traveler still paralleling. Decided to stay submerged after covering twilight to determine if searchlight sweep was successful or because our presence was suspected.
Searchlight sweep commenced on schedule. Surfaced. If JSBS brought ships to port with searchlight, a submarine approach excellent procedure especially with new moon to aid visibility.

crab-like smoko, Sea was smooth as usual for this area. A zig foroad us to swing TAUTOG in front of destroyer to a firing course. We just made it, for a periscope exposure bearing dead astern revealed about six square foot of destroyer side plating, in high power, and nothing close. Yet this DD never spotted us. Fired six fwd torpedoes spread at three ships, lowered scope and swung TAUTUG at full speed. Heard loud explosion of torpedo 3 minutes 36 seconds after firing of 1st torpedo. Ships zigged toward us necessitating only a swing of 120° for TAUTUG to obtain 100° track for stern tubes. Fired three stern tubes. Shortly after 3rd fish fired, a loud bang and crack which felt like an aircraft bomb caused us to cease attack and duck down. 36 seconds after 1st fish fired, heard torpedo explosion believed to be a hit. During eight minutes accounting for all torpedoes, Analysis of times of explosion, ranges and times firing, shows that one bow and one stern were almost certain hits and possibly one or two more. Sercws were heard in every direction, high and low and a copious quantity of pinging. Between 1307 and 14C3 received 16 depth charges two at a time. They were heavy ones but never close, although each one caused an excessive swirl of water in superstructure which would normally be accompanied by a shaking consider- ably more severe than sustained this date. Returned to periscope depth, had run west and N.W. to evade. Two A/S vessels were pinging and searching about 5000 yds to east of us. Sighted large column white smoke and broad black smoke between us and port. No smoke could be sighted in any direction except that of port entrance. Ran N.W. for romainidor of daylight, gradually leaving A/S behind. Never sighted smoke to north, but saw it in direction of port for several hours. Concluded convoy had returned to port and believed one or two wore damaged. Surfaood on course 320°T, set speed 16 kts.

    heavy smoke was soon issuing from the large building for a
    short period, following which time, only small traces of
    smoke were noticed.

There was an interval of over four minutes following the ninth explosion before the first depth charges began to detonate. From an analysis of the above times, the first two explosions must have been torpedo explosions taking into consideration the possible ranges by plot and running times of the two different type torpedoes fired.

A running time of approximately six minutes for MFL.14 torpedoes and seven to nine minutes for MFL.18 torpedoes has been experienced. Using these times accounts for the last seven explosions.

Incident to close explosion of own torpedo the QC sound head was forced up several inches. Four set screws holding the training gear to the bearing assembly wore pulled out, the bearing ring dropped, and inner race was forced up. The shaft of a small gear which runs Sol-syn motor for the angle indicator was bent about 50°. Ship's force effected repairs and sound head was back in operation within 24 hours.

29 October
Discovered small orack about one inch from top of #2 liner #1 main engine. Renewed liner.

31 October
Flexible coupling of auxiliary engine carried away.

In general: the performance of machinery on the TAUTOG was excellent, probably the best of any patrol to date. The TAUTOG received a good overhaul at HUNTER'S POINT followed by some excellent work on the part of the crew. Repairs and adjustments made by U.S.S. GRIFFIN at PEARL HARBOR were a final touch to place TAUTOG in a fine material condition. The major casualty, namely the auxiliary engine has been a "bug" since commissioning of the TAUTOG. The performance obtained from this engine for effort expended in repair is a very low percentage.

(L) RADIO
TRANSITIONS: As far as radio transmissions were concerned, excellent results were obtained. Of the eight messages sent, three were disposed of directly to NPM while the other five were routed via VLM. VLM answered our first call on each occasion, either by tolling us that he would retransmit or dispose of our traffic, or that he would notify NPM that we were calling him.

VLM was right on the job, and excellent results were obtained with a minimum of time on the air for each message. One occasion NPG (San Francisco), and VLM both gave us a strength five signal and informed us that they would dispose of our traffic.

TAUTO6 transmitter is in good condition, and of the three contacts with NPM, he gave us a maximum signal strength.

4235 Kes were used on all but one occasion, when 8470 Kes were used. This shift was made due to the transmission being sent during daylight hours, and we were

(M) RADAR

Prior departing PEARL HARBOR the new type SJ-1 transmitter was installed. This apparatus is of more delicate nature and demands more attention than the model SJ, however, the added maintenance work was more than adequately compensated by the excellent ranges obtained. For this run the TAUTOG was added by having aboard a special Radar Officer, Ensign A. J. GARON, and an excellent 1st class electrolian's mate, J. C. CLIREHUGH.

Dototable signals were rendered on ships up to thirty thousand yards, while land showed up as good pips up to approximately sixty thousand yards. Skillful operation is definitely a factor in such performance. However, a constant annoyance was a recurrent failure at various times of sweep trace disappearing from screen.

(N) SOUND GEAR AND SOUND CONDITIONS.

In area within six mile radius of eastern entrance MALAKAL HARBOR sound conditions poor due to background and roof noises. JP sound gear for relative bearings from 220 around bow to 140° definitely superior to JK & QC. Targets were picked up at greater ranges and screws were often heard by JP that neither JK or QC could pick up, although they were coached on by periscope bearings. Sound conditions on west side of PALAU ISLANDS were good. Temperature gradients are greater there, than on eastern side making super-sonic more inaccurate.

Bathythromograph was a material aid to Diving Officer. In P.L.U.A. area ship was light at deep depths.

(PP) HEALTH, FOOD, AND HEALTHBILITY

Air conditioning was improved at navy yard and results appreciated. TIJTOC's starboard stateroom was converted to a bunk room of six bunks. In carrying more than six officers in complement this arrangement is most satisfactory. With eight officers on board this patrol none slept in wardroom and no one was inconvenienced or embarrassed.

Mark 18 torpedoes, however, were a strain on all hands until a few were fired. The forward torpedo room was uninhabitable. Bunks were tried up in wardroom passageway, gear was constantly being shifted, racks always on the move, and chain falls constantly in operation. Only four men slept in forward room at this time, causing eight to hot bunk in after room and crew's compartment. It is recommended that until torpedoes are modified so that they may be vented in the tubs, Mark 18 torpedoes should be carried every other patrol, or only 13 torpedoes forward should be taken at one time.

Food was excellent. A variety of frozen foods were never available to TIJTOC in her patrols in the SOUTHWEST PACIFIC and were thus a real treat this patrol.

Health of personnel was good.

(Q) PERSONNEL

Performance of duty of personnel was of a high standard. Stress on qualification of new hands was maintained. Three ensigns made their first patrol this trip and enthusiastically gained needed experience.

1. TAUTOG Eighth War Patrol, the first after Navy Yard overhaul, extended over a period of 41 days, 13 days of which were spent in assigned area. Patrol was terminated by expenditure of torpedoes.

2. There were six worthwhile contacts made in which TAUTOG was able to close to firing range and make aggressive attacks:

   (a) 1431, 28 October, two Mark 18 torpedoes failed to damage a tanker at 2800 yards. A small explosion was heard after a 4 minute run indicating a possible low order detonation.

   (b) 1550, 28 October, a hurried set up for a stern shot after a radical change of enemy course resulted in four Mark 14 misses at 750 yards because TDC speed setting was not changed from Mk 18 to Mark 14 torpedo speed.

   (c) 1045, 4 November, when 2 enemy ships of 6 ship escorted convoy were in line four Mark 18's were fired resulting in timed hits in each of 2 ships similar to AKITA HURU. One is believed to have sunk and other damaged.

(d) 1252, 5 November, convoy of 4 escorted ships was fired at with bow and stern tubes closely followed by depth charging. One liark 18 from bow tubes made a timed hit as well as one liark 14 from stern tubes on different ships estimated to be 3 to 5000 ton freighters. One or two more hits may have been obtained.

(e) 2359, 6 November, one timed hit was obtained after firing 2 liark 18's in a night radar periscope attack on largest vessel of an escorted 3 ship convoy consisting of 1 tanker, 1 freighter, 1 passenger freighter and 1 destroyer.

(f) 1820, 7 November, last remaining liark 14 failed to hit tanker of this same convoy.

3. TAUTOG sent contact report of this convoy and most effectively trailed it for 2 days sending out course changes enabling another submarine to get in an attack.

4. Successful shelling of Pais Island was conducted at range of 4000 yards firing 57 rounds of 5" common and point detonating projectiles. 18 hits were observed in phosphate plant and others in nearby radio installation.

5. TAUTOG returned in good material condition. Refit will be accomplished in normal period.

1. The eighth war patrol of the U.S.S. TAUTOG was conducted after an extensive new yard overhaul. The TAUTOG patrolled in the area around Peleliu.

2. The patrol was an extremely aggressive one. The fire control party difficultly experienced early in the patrol smoothed out considerably toward the end.

3. In addition to making five aggressive attacks the TAUTOG trialed a convoy for two days, sending valuable contact reports that enabled another submarine to make a successful damage attack on the enemy.

4. The TAUTOG also carried out an aggressive and successful bombardment on a phosphate plant on Peleliu, causing considerable damage.

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

6. The Commander Submarine Force, Pacific Fleet, concurred that the Commander's Officers, officers, and crew for this aggressive patrol. The TAUTOG is credited with having inflicted the following damage upon the enemy:

U.S.S. TAUTOC

NARRATIVE (Cont'd)
Inev she was zigging and would turn to her left to pass SHIMO MISAKI LIGHT. Target zigged to course 100°T. Passenger steamer in company with target in column Dog on far side of freighter. C/C to 005° to fire. Near escort crossed our bow at range of about 300 yds. Fired spread of three torpedoes at freighter, range 3000 yds, 110° track. About 100 ft of open water between stern of freighter and bow of passenger ship. Near escort was signalling with escort metering him from east. Started to fire one tangle torpedo at this rendezvous but gyro angle too large. Fired spread of three torpedoes at freighter and passenger ship, and commenced a swing to westerly course. Two PC boats began maneuver ing toward torpedo tracks. Heard two explosions believed to be hits. Escorts between targets and TAUTOC. TAUTOC went deep. Received forty-nine depth charges. Four or five A/S vessels were making runs on us. TAUTOC ran silent with excellent depth control. No temperature gradient to 250 ft. Slowly C/C to run south, impossible to maneuver as vessels were picked up on all sides. No damage was suffered near east charges being about 200 to 300 yds. Charges were dropped in salvos ranging from one to five at a time. Heard three distant explosions distinctly different from depth charges and hoped it was internal ship explosions of targets. Received forty one depth charges. These were all astern or on quarter. Two vessels made runs with third and forth probably stopped, listening, and pinging. Only once in this period did an A/S vessel go ahead of us. She may have made an attack to southwest of us. Came to periscope depth. Nothing in sight. Surfaced on course 190°T. Went to speed 13 kts to clear area and charge batteries. A fine dark night. First of four airplane flares dropped astern of us. Estimate flares about 6 to 8 miles distant. TAUTOC surfaced about 12 miles south of attack position. Flares were brilliant parachute type and burned for 2 to 4 minutes. TAUTOC not spotted.

U. S. S. TAUTOC

NARRATIVE (Cont'd)
Sighted ICHIE SAKI LIGHT bearing 012°T.
Radar contact bearing 330°T. "Sent to battle stations. Soon determined five to eight ships proceeding aloft to escort beached ship. Visibility poor, tracked at range of 6000 yds. Visibility poor, ships could not be sighted with land background. Smaller ships detached escorts between us and targets. Decided to run ahead, get on their track and attack at dawn.
Submerged about two miles south of SHIONO ISSAKI LIGHT. Ejected targets, if they were same, to pass us in twenty minutes and believed visibility would be sufficient to enable a successful attack.
No targets in sight. Three escorts on various courses and at various ranges around us. Escorts were signalling. Sighted mass of larger ships, (at least two), bearing 300°T. Believed they were stopped or circling. No believed that we may have been spotted, possibly we were seen from beach by light house or signal station personnel. Commenced approach toward targets. PC boat with fleets hoists estern of us signalling constantly.
PC boat approaching steady bearing. C/C to 270° to get off her track. At range 300 yds or less started deep at slow speed.
PC dropped three depth charges. They were close but fortunately for us set shallow. High speed screws now maneuvered all around us. TAUTOC gave up attack and maneuvered to clear area.
One depth charges.
Two depth charges.
One depth charges. These were dropped after apparent tracking and methodical runs made to releasing point.
Came to periscope depth. Sighted two A/S vessels astern searching. Sighted float type plane circling low over water.

U. S. S. TAUTOG

NARRATIVE (Cont'd)
1 January 1944

Submerged. Had planned to patrol east of SHIONO ISAKI LIGHT, CURRAND having left this area. A morning attack east of light has advantages of better background and light, plus fact that it is believed escorts are relieved at this light by a new set. Thus an attack at the light must be made with opposition of two sets of escorts. Due to current found ourselves out of position at dawn. Planned to apply our theory next day.

Two distant explosions. Nothing in sight. Surfaced. Night patrol. Maneuvering to attain position off KAIKORI SAIKI LIGHT.

2 January 1944

Sighted KAIKORI SAIKI LIGHT bearing 320°T. Submerged. Sighted five or six motor sampans with fishing nets during early morning.

Sighted plane steering 236°T.

Sighted smoke: "Sent to battle stations and commenced approach.

Secured thought smoke false alarm.

Resighted plane over KAIKORI LIGHT.

Sighted ships bearing 322°T headed north along coast. These ships had slipped by us. A recheck of our plotted position proved we had wrongly identified objects on beach and we were farther off shore than we thought. Hence believed impossibility, (ships passing between us and land undetected), had occurred. Commenced high speed run for KAIKORI LIGHT to north to attempt to cut off ships following coast line. Chose was unsuccessful. Continued sight same plane or similar one through out afternoon.

Heard heavy distant explosion.

Surfaced. Moonlight.

SD Radar detected plane 11 miles distant. Plane closed to 7 miles then opened range and disappeared at range of 13 to 14 miles.

3 January 1944

Sighted KAIKORI LIGHT bearing 293°T. Sighted group of fishing vessels proceeding south along coast.

6 January 1944

Lights at KNOTORI SAKI and MIKI SAKI previously observed lighted, not sighted this night.

Submerged.
Sighted a float type plane. From this time until about 1600 had one or more patrol vessels in sight. Would start an approach only to discover supposed target to be an other patrol vessel. Only one pinged. Some lay to for intervals. If JAPS were running ships along coast this date an approach would have been practically impossible.
Surfaced. Right moonlight. Decided to head for ICHIE SAKI. This coast well protected and next morning would be last time this patrol that beach could be closely approached on surface due to moonlight. Hoped for a night attack as when ships move east along coast we believe they pass ICHIE SAKI at 0400 (-9). Moonset 0414 on 7th.

7 January 1944

Rough weather encountered on rounding SHIONO MISAKI. Hail, snow and sleet fell at intervals.

Sighted ICHIE SAKI LIGHT. Seas abating somewhat. Encountered strong N.W. current about 5 to 6 miles off shore south of ICHIE SAKI.

Radar contact bearing 348°T. Bright moon-light, exceptionally clear. Determined two ships plus escorts passing DAIO S.SKI LIGHT on easterly courses. Ran to position ahead and then turned toward them. Sighted two ships, largest leading on starboard flank, two escorts on port flank at range of 14,000 yds. Submerged to 40 ft depth at range of 11,000 yds and continued to take radar ranges and bearings. At 7000 yds could see ships well in periscope, went to periscope depth. At 3000 yds range burned off track of largest ship toward beach on opposite flank of escorts.

: 2317
Fire spread of three torpedoes from stern tubes at large leading freighter. Ship appeared to be bigger than ship attacked on 4th in this same spot. Fire of fourth stern torpedo at smaller freighter. Estimated her size as 4000 tons. One torpedo of first three was observed to hit on time with estimated range 2300 yds. Observed an escort bows on heading for TAUTOC. TAUTOC went deep swinging to right to parallel 100 fathom curve. A second torpedo explosion was heard and time showed 2 minutes 25 seconds from firing of fourth torpedo. Screws of both ships stopped.

: 2323
First of a series of twenty-two depth charges. First few were quite close. Two A/S vessels were attacking, one pinching constantly. TAUTOC's evasion course was least probable and threw them off. Considerable breaking up noises heard in direction of target.

(B) NARRATIVE (Cont'd)

Vent to full speed and cleared area on course 110°T. White smoke from engines provided an effective score.
C/C to 180°T.
Submerged. Shortly thereafter heard a series of distant heavy explosions. Perhaps the "versity" had made a supposed contact some 15 to 20 miles astern. TAUTOG about 45 miles from scene of attack. In view of fact that targets stopped after being hit, that two 4/S vessels observed stayed in vicinity and were only vessels sighted on surfacing, believe it is reasonable to assume that ships hit sank.
Surfaced. Rough seas. Proceeding on south westerly courses.

(J) ANTI-SUBMARINE MEASURES AND EVASION TECHNIQUES
Airplane flares dropped on evening of the 27th December after surfacing following a day's depth charging was a new experience for the TAUTOG in regards to JAPANESE Anti-Submarine Measures.
Escorts of PC boat size are used in copious quantity to protect shipping along coast. Their sound gear both listening and pingers continues to be fairly poor in regards to the TAUTOG.
The carrier contacted on the 17th of January had four escorts. One was placed on each quarter about 2000 yds. When carrier zigged escorts position seemed to remain on true bearings from the carrier, i.e. one would be ahead, one astern, and one on each beam.
The TAUTOG was extremely well handled during evasion in depth control by Driving Officer, Lieutenant Tom TURNER. Whenever ship became heavy, negative tank was filled by blowing water from auxiliary and then blown overboard quickly, immediately following an explosion. Pumping was never resorted to and JAPS never located TAUTOG. The TAUTOG always endeavors to get as far from the scene as possible. A gradual change of course is favored rather than radical ones. A quiet constant speed with little rudder or plane movement is used rather than bursts of speed.

(K) MAJOR DEFECTS AND DAMAGE
1. Crack in starting air passage, #6 head, auxiliary engine. Water cracked through bolt hole to head allowed water to leak into lub oil system. Renewed head and liner.
2. On two occasions a locking pin on a selector of main controllers carried away. In each case selector was thus locked in position causing loss of control of main power. Pins were renewed. Present pins are 5/16" in diameter and are too weak. It is suggested that pins be replaced by stronger ones of 9/16" diameter.

— page 139 —
5. Following depth charging on 12 January outboard supply ventilation piping developed a bad leak. Outboard valve appears to be satisfactory. Leak is noticeably increased at deep depths.

: 4. Due to misalignment of sheaves for hoisting cable, No. 1 periscope was temporarily out of commission during patrol. Ship's Force manufactured new sheaves, installed shims and bushings for temporary repairs. Correct permanent alignment is needed as well as new cable.

: 3. Incident to shipping water on one instance on 20 January, the following electrical equipment was grounded out and will need a thorough overhaul.

(a) Both H.P. air compressor motors.
(b) Both periscope hoist motors and panels.
(c) Air conditioning circulating water pump motor.
(d) Auxiliary engine generator.
(e) Main engine detached circulating water pump motor.

H.P. air compressor motors were immediately washed out with battery water, cleaned, dried out, and wiped with carbon tetrachloride, but grounds persisted. Considerable electrical repairs will be necessary during coming refit.

: 6. As a result of depth charging or defective material a lug for the dog on port pressure proof stowage for 5" powder carried away, permitting stowage to flood.

: 7. A major defect of T.U.T.O.C is a roaring noise submerged, caused by some vibration in conning tower fairwater which occurs at speeds over 4.5 kts. A search for possible source has been fruitless. Antenna supports are scoured at present to fairwater plating, if moved forward to a frame, (i.e. "II" beam), this disturbing noise may be eliminated.

(L) RADIO

Reception of the submarine schedule was excellent at all times, with a minimum of interference. Recommend the continuance of 4525 Kcs until 2100 G.C.T. The added power on 4525 Kcs was appreciably noticeable.

CONFIDENTIAL

(L) RADIO (Cont'd)

Three messages were transmitted while in the area with a minimum time of delay. NPM answered our first call on each occasion and received us at strength Five. 8470 Kcs were used on all transmissions and only a small amount of jamming was noted.

(M) RADAR

During refit before this patrol a Plan Position Indicator was installed supplementing the new SJ-1 transmitter. The PPI is invaluable in search and in determining relative position of ships in a convoy. It also lends itself useful in navigating from coast line.

With the exception of the type training gear, which is noisy and difficult to operate in hand, the performance of the SJ Radar was excellent. Ensign CARON on one occasion while searching with no knowledge of enemy ships present detected a ship later attacked at a range of 24000 yards. Such ranges on good size ships are normal for this radar if approximate bearing is known. In this case the detection is worthy of special mention.

SD Radar spotted one plane at night. During bright moonlight SD was used intermittently. SJ sweeps were made about once every five minutes throughout night patrols. No evidence was detected that enemy is "D.F."ing", or is aware of the presence of either SD or SJ Radar in this area. Interference on screens was often noted, but could very well have been due to U.S. subs in adjacent areas.

(IN) SOUND GEAR AND SOUND CONDITIONS

Sound conditions in area varied from poor to good depending on proximity to beach, and sea conditions. In general typical personnel performance was observed, i.e. fair-ly poor sound reception prior to an attack with marked improvement during evasion.

The JP continues to outrange the JK and QC receivers as previously noted on eighth war patrol.

The QC training gears are not properly meshed. A re-alignment is imperative for proper functioning of equipment.

Note: Depths greater than 250 feet were only held for a short time, necessitated by the trim and situation.

(P) HEALTH, FOOD, AND BASTABILITY

All previous war patrols of TAUTOG were made in tropical waters. A tremendous difference was experienced on this patrol with air temperatures about 40°F. at night. Air conditioning was no problem. Submerged, personnel felt refreshed after sleeping. Water consumption was greatly reduced making still operation easier. A cold weather patrol is much less fatiguing than a warm climate run. Several officers and men were relieved from watches for a few days due to colds, earaches, and toothaches. All hands endured the rough weather in fine fashion.

Food was excellently prepared and cooks received well merited praise.

The TAUTOG is badly in need of fumigation which will be accomplished during coming refit.

(Q) PERSONNEL

The general attitude of officers and men as we enter the third year of the war continues to be excellent. The Commanding Officer feels that our policy of rotation is the most important morale factor. Although the average experience of personnel is constantly being lowered performance is not being reduced. An enthusiastic new hand, (and most

U. S. S. TAUTOC
:  CONFIDENTIAL
:  (Q) PERSONNEL (Cont'd)
:  of them are), acts as a stimulating tonic. Veterans take
:  delight in demonstrating their knowledge and feel more keen-
:  ly their responsibility. An orderly transfer of experienced
:  personnel must be effected each patrol or the boat may suffer
:  unduly for one patrol. The TAUTOC is well balanced except
:  for electricians. Because of difficulty in obtaining replace-
:  ments in this vital rate, and because old hands volunteered
:  for more patrols, half of force should now be transferred.
:  Many men are willing to do more than their share, but morale
:  is best maintained by equalizing the load.

The problem of change and standards is far
easier on the operating personnel than on the overhaul. The
pressure is always present to maintain certain efficiency
standards at sea. At the base this pressure must be artifi-
cially stimulated. However, as operating personnel become
less and less experienced, the success of the boats will de-
pend more and more on the efficiency of the refit.

(U) REMARKS

It is believed that there is little shipping in this area except close along the coast. The Commanding Officer takes a very dim view of a daylight submerged attack on the coastal shipping. It is well protected. Difficult to sight. The submarine is very apt to be detected prior to attack, and may be certain of considerable retaliation after attack. A night attack offers the best chance of success. It is not believed that the coast is protected by radar, but it must be well watched by observers. Therefore, a night attack depends on the moonlight or visibility conditions.

It is strongly recommended that a submarine not be restricted to an area east or west of SHIONO MISAKI LIGHT, but be able to work the coast in both directions as was the TAUTOG. Then, by observing ship movements an advantageous spot may be selected depending on weather conditions, visibility, and suspected times of passage of vessels.

Subject: U.S.S. TAUTOG (SS 199), Report of War Patrol Number NINE.

1. The ninth War Patrol of the TAUTOG was conducted in the area Southeast of Shikoku Island and South Central coast of Honshu Island. It extended over a period of 49 days (lifeway to Pearl), 24 days of which were spent in the assigned areas.

2. Excellent area coverage was maintained throughout the patrol, although a total of 25 days were spent submerged. Daylight submergence was necessary because of the many Japanese air and surface patrols maintained in those areas.

3. Two daylight and three night attacks were conducted, all of which were aggressive and skillfully handled.

Attack number one damaged or probably sunk one freighter and damaged another. After this attack ninety-nine depth charges were dropped over a period of 4 hours. The excellent depth control, silent running and evasive tactics employed enabled the TAUTOG to escape.

Attacks number 2, 3, and 4 were highly successful and productive, resulting in the sinking of two small freighters and two large freighters. Following attack number 4, twenty-two depth charges were dropped.

Attack number 5 was a night surface radar attack on a carrier protected by four escorts. Unfortunately this valuable target decided to zig away before the TAUTOG was able to close. The TAUTOG fired three long range shots in low power. As the target did not reduce speed, it is believed no hits were made. Two explosions were heard, which undoubtedlly was due to torpedoes exploding at the end of the run.

Subject: U.S.S. TAUTOG (SS199) - Report of Ninth War Patrol.
(12 December 1943 to 30 January 1944).

1. The ninth war patrol of the TAUTOG was conducted in an
Empire Area.

2. Extremely good coverage of all traffic lanes along the
Empire Coastline was conducted. All attacks were well planned and
aggressive. The sinking of a freighter about one-half mile from a
Japanese town was very well done.

3. It is of note that enemy anti-submarine measures along
the coastal routes are becoming extremely effective in the day time
and during full moon periods.

4. Insufficient evidence prohibits the crediting of more
ships sink, but it is believed that some of those credited as being
damaged were sunk.

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

6. The Commander Submarine Force, Pacific Fleet, congratulates the
Commanding Officer, officers, and crew for this very aggressive and
successful war patrol. The TAUTOG is credited with having
inflicted the following damage upon the enemy:

dist. 8 miles. Observed patches of slush ice on
water in strait. Clear calm day.
Surfaced for night patrol in OITOTAI KAIHYO.

11 March 1944

Submerged South of US.S.S. T.LUTOG was light
at first, probably due to ice on superstructure.
Later temperature about 20°F. and air about 28°F.
Periscopes and vents worked satisfactorily. Heaters
were rationed submerged to conserve battery. Patrol
this date hampered by ice floes. Periscope left a
noticeable wake and iced quickly when exposed. At
times T.LUTOG was completely surrounded by a solid
mass of floating ice about 2" thick. Noted radio
towers and buildings on beach as previously described
in intelligence reports. Light house had a
noticeable tilt to eastward, indicating possible
damage. Took pictures and movies of coast line.

12 March 1944

Wind and sea increasing from N.W.

SILSUKOT.LN TO Island beach to starboard distant
15 miles.

Submerged on course 237°T with T.LUTOG. Island dead
ahead distant 22 miles. Seas too rough for satisfactory
factory periscope exposures without broaching.
Snow fell at various intervals during day. Late in
afternoon observed several buildings, airport, pill
boxes, and radio towers as described in intelligence
bulletins.

Surfaced in rough sea. Decided to send radio message
to ComSubSpaFue just to let Japs know we are here
and P.R.HUSHTU patrol would at least accomplish
some good. Tould send message east of KORILIS.
Then proceed thru US.S.T.LUTOG and run south in
sea of OIOTSI to west of UIRIIIS.

Completed radio transmission. C/C to 230°T with
seas on quarter could make 12 kts.

13 March 1944

On course 227°T proceeding southward towards YARFUTO Strait. Decided to remain on surface at dawn.

Radar contact, bearing 110°T., distance 19,000 yds. One pip and no more. Thought it was a phoney but proceeded on ther bearing. Sighted masts of a ship and started tracking and making an end around. Could not approach to radar range for fear of being sighted. Also, could not keep ship in sight with high periscope due to variable visibility which could quickly change and permit us to be easily spotted. T.U.TOG could make a maximum of 15.3 kts on four engines. Another reminder not to decommission vents on fuel ballast tanks or have a simpler conversion method.

Submerged ahead of target about 7 miles S. of RSHUT. To Island. Had over estimated speed of target sighted her about 125 and commenced approach. Target apparently alone. Proved to be exactly similar to T.G. ILRU, page 266 ONI-J (Revised).

Fired three torpedo spread at range of 1500 yds. Two hits observed on time. One put a hole thru her bow above water line and one hit aft in engine room. Ship stopped and lay to down by stern. All hands alive abandoned ship. One life boat was filled with about a dozen men. Fired one stern torpedo at ideal range and track. Torpedo apparently broached for it exploded 2 minutes after firing. Probably set too shallow for seas. T.U.TOG circled and fired a bow fish from 1000 yds. 30 track at stopped ship. Torpedo seen to broach, heard to stop, and explosion heard and felt 2 minutes 37 seconds after firing. Ship was not sinking and life boat was standing by. Fired another approach to sink this ship. Fired one torpedo and observed smoke of torpedo (too rough to observe wake) to pass under target. Sound followed this torpedo to target. Then this missed, fired another torpedo from bow tubes and observed it to run astern. No were now pretty mad. Is no air or surface protection was evident, surfaced to sink ship with 5" gun. Opened at range of 2000 yds. and fired about 12 rounds. First shot hit at base of steel. Seas made firing difficult with crew drenching by icy water. Closed range to 700 yds. and fired about 18 more rounds. Hits demolished bridge after deck house and put about 8 holes in side. But rubber ship still floated.

C/C to 253°T.
Surfaced south of SHIBOTSU YAN, HOKKAIDO.
Radar contact, bearing 045°radiative. Commenced
tracking at range of 19,000 yds. Visibility light
haze. Soon determined enemy consisted of about a
seven ship convoy. Ships were zigging, at least
one escort present, and were spread out in a loose
formation making actual combat difficult. For ex-
ample: Ranges would vary from 10,000 yds to 18,000
yds. for nearest and most distant ships. Maneuvered
to attack ship on starboard flank, charging main
storage battery enroute.
Fired four fish spread from bow tubes at ship at
range of 1500 yds. Visibility was such that target
appeared as a black mass. Both TBT operator and
SJ Radar spotted another ship almost in line of
bearing beyond target. One torpedo hit target on
time (1 min. and 3 secs.) causing a tremendous
observer explosion. J.O.O.D. was watching what
appeared to be an escort on starboard bow. Just
prior to firing, observer this vessel to turn to
ward TUTOG and reported range closing verified
by Radar at 2500 yds. TUTOG swung away after
firing, cleared bridge as first torpedo exploded
and submerged. 1 min., 32 secs. after firing 2nd
torpedo and 1 min., 31 secs. after firing 3rd tor-
pedo heard two torpedo explosions believed to be
hits in ship beyond target. Soon determined that
escort had not located us or else did not choose
to doph charge us. Considerable breaking up noises

consisting of numerous explosions were heard thru null and on sound gear in direction of attack. Came to jeriscope depth but too dark to see. Sound could hear distant screws. Planed up to 40 feet and took SJ Radar sweeps but could pick up nothing. Surfaced on course 210°T. Picked up ships range 10,000 yds. bearing 090°T. If ships hit stopped they also sank for TUTOG made a half circle submerged and could not have been this distance from them. Commenced tracking again and found snips were zigzagging, radioing from 090°T to 180°T with a base course of about 140°T. It appeared that this convoy was pursuing a revolutionary route for some southern destination. Maneuvered to attack convoy again from starboard flank. Had 3 torpedoes forward and 7 air-tormenting. Firec. three torpedo spread from bow tubes, range 2700 yds. 80 track on course 050°T at a medium sized ship and at once swung right with full rudder. One torpedo hit causing a violent explosion. Stoached on course 207°T to fire stern tubes at target just ahead of target hit. Fired four fish spread from stern tubes at range 2850 yds. Three explosions occurred at 1 min., 47secs., 1 min., 54 secs. and 3 min., 12 secs. First two were hits on target. Third, undetermined. Target hit by bow torpedo was observed to be stopped sinking. Several minutes after stern tube explosions second target disappeared on radar screen. Radar Officer determined that there were six ships at start of second attack. As we hauled away, only four could be detected. At this time a ship determined to be an escort and probably a destroyer apparently attempted to close. TUTOG tracked and changed course constantly to open range. Speed of convoy was 9 kts, this vessel making 17 kts. TUTOG finally started to open range on course 180°T. Other ships were lost on Radar screen during this evasion. For next one hour and a half about four-ton heavy explosions believed to be depth charges were heard. ...

Damage Determined by Visual observation

Details of Action

TAUTOG surfaced with the range about 1300 yards and
expended thirteen rounds with the range opening. Then circling and
approaching to within 600 yards seventeen rounds were expended at
the then abandoned hulk. At this time, another ship was observed
approaching, range 18000 yards bearing 235°T. and TAUTOG was forced
to abandon this attack in order to make a submerged attack on the
newcomer. After submerging, the target was observed to be burning
freely and listing heavily to starboard. At least 15 hits were
observed and bridge and superstructure were demolished.

5. First northbound TUG: ...U contacted west of RASHIDA. Island was about three hours ahead of second which was be- ing escorted. The latter had probably dropped behind schedule. Morale for Japs: Stay with your escort!
6. Attack on convoy proved very definitely that no ship present had Radar or Radar detectors except TUTOG. The TUTOG submerged on a better safe than sorry principle after first attack but lost temporarily the offensive in so doing. She could probably have safely evaded on the surface.
7. It is believed that our gray camouflage was ideal for the hazy visibility that night.
8. The TUTOG has often been pinged deaf on previous patrols. Not one single enemy super sonic squeak was heard this run. To our less fortunate comrades all the TUTOG can say is that she has had tough runs too.
9. (K) M.JOR DEFECTS AND DILIGENCE.
10. The TUTOG received an excellent refit from U.S.S. BUSHIELL. All known defects or change is of minor nature and a routine refit is anticipated following this patrol.
11. Two separate oil lines should be fitted in tanks Nos. 5A and 5B R.F. IBTS to insure that all fuel is obtained from both sides. It present connection to fuel oil transfer line is one line.
12. TUTOG has not been docked for three patrols. Com- manding Officer feels that a boat of this age should be docked at least every three patrols or six months for inspection alone whether or not work is required.
13. Three life lines or wires will be requested in vicinity of 5" gun. It is too easy to slip under a single or even a double wire which may be no better than none at all.
14. It is believed that an improved TBT and binnocular holder should be designed. Present mountings are too flimsy and awkward.

8. The SJ Radar was erratic in operation shortly after leaving PEARL HARBOR. Enroute to PEARUJSHIRO it was discovered that a control unit was not grounded. Good results were obtained while on station. Almost immediately after firing 5" gun, it was noted that several tubes became defective. This casualty can usually be anticipated after firing.

9. The SD Radar was used when 'entering and departing from area but not in area as weather conditions for most of the time precluded night flying.

Subject: U.S.S. TAUTOG (SSL99) - Report of Tenth War Patrol - Comments on.

1. The tenth war patrol of the TAUTOG was conducted in the KURIL ISLANDS AREA and off the Northeastern coast of HOKKAIDO, JAPAN.

2. This is another outstanding and aggressive patrol, typical of the TAUTOG and her Commanding Officer. There were four contacts worthy of torpedo fires and three of these were developed and successfully attacked.

3. (a) In attack number two, a torpedo spread was fired submerged at an unsorted freighter similar to TAGA HARU resulting in two hits, stopping her and causing her to settle by the stern. Two subsequent torpedoes pre-matured and a third passed under the target. TAUTOG then surfaced and opened up with gunfire. After numerous hits, ship was still afloat, when the masts of another ship were sighted on the horizon.

(b) Attack number two. After a submerged approach this ship, a twin of that in first attack, was hit by one torpedo of a three torpedo spread and sank shortly thereafter. Subsequent observation disclosed the original shelled target down by the stern, listed and heavily on fire.

(c) Attack number three - was conducted at night on surface against a convoy of about seven ships with at least one escort. The first phase consisted of a four torpedo spread fired at an unidentified medium sized ship at range 1,500 yards, with another ship almost in line and beyond target. One torpedo hit target with a tremendous explosion, and two torpedoes were heard to explode thirty seconds later indicating hits in ship beyond target. On near approach of escort, TAUTOG submerged and numerous breaking up noises and explosions were heard in direction of attack. After surfacing, TAUTOG regained attack position on convoy and in second phase of the attack fired a three torpedo spread at a medium sized ship.

Subject: U.S.S. TAUTOG (SS199) - Report of Tenth War Patrol.
(24 February to 23 March 1944).

1. The tenth war patrol of the TAUTOG was conducted in the Kurilo Islands and off the Northeast Coast of Hokkaido, Japan.

2. The patrol was well conducted, showed plenty of determination, and was extremely aggressive. The series of running attacks in the early morning of 16 March on the seven ship convoy were particularly outstanding and most productive.

3. It is of note that the new type of winter clothing carried and used by the TAUTOG was most satisfactory in the severe weather encountered.

4. The gray camouflage, which has been so effective in all of our other Empire Areas, appeared to be particularly so in the foggy and snowy weather encountered in the Kurilos Chain.

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

6. The Commander Submarine Force, Pacific Fleet, congratulates the Commanding Officer, officers, and crew for this aggressive and outstanding war patrol. The TAUTOG is credited with having inflicted the following damage upon the enemy:

After a 4-engin chase, and at range of.7,500 yards, lights could be seen on target. At 5,000 yards, lights turned out to be normal running lights with green-red-green display on mainmast, making him a Russian or reasonable facsimile thereof.

Broke off attack. This affair had led us too far from any possible dawn diving position off P.R.A. NUSHIRU, so we trailed target for a while to ascertain his good intentions. He seemed to be definitely headed for FIRST HURILITE STRIKE. At 0134 J
Herald soundwaves, running on surface inboard of HURILITE chain.

Dove 5 miles east of H.TSU. Took. Closed to look it over.
0737 J
Off southern tip of H.TSU. and could see AT an anchor between B.JO TO and H.TSU. (ship contact #4). He had a zero track from this position, so worked up through strong, shifting currents to firing position north of B.JO TO. Made out 6 travelers apparently at anchor to right of AK, which was now identified as RYOYO HURU class, 6,000 tons. Turned to course 210° for straight bow shot, when sound reported severe to north of us. Could see three ships on a quick look (ship contact #5), with small port angles on the bow, but did not classify them, as considerable navigating was necessary in these currents 1000 yards from the rocks.
1123 J
Fired 4 torpedoes at RYOYO HURU, spread from bow to stern, at 2000 yards. One hit, which completely obscured target with spray. Missed probably due to currents. Tied rips, though none of them exploded on hitting the beach. (torpedo attack #1). Swung left to get clear of B.JO TO; made ready 2 remaining bow tubes for possible shot at incoming ships, but a second look revealed them as travelers, with deck loads of cargo. Made reload forward, and came back to position for anoth look at RYOYO HURU. She was deep in water, and listed slightly toward us.

— page 182 —
1236
Distant aircraft bombs began falling.  e figured our hit on last salvo was by torpedo aimed at bow so set target speed at 2 knots to allow for current, which was about opposite to his heading.  This set-up checked perfectly on T.D.C.
1250
Fired 2 torpedoes at RYOYO M.R.U. (attack, 2), 'spread 1/3 of his length, at 2800 yards.  2 minutes, 20 seconds after firing, 2, heard muffled explosion and saw light haze rise from target.  No noise from other torpedo,  Swung left to clear land.  Decided against further expenditure of torpedoes on this handsome target, as currents and shoals made hits anything but certain, and numerous cuts on target had shown him in spot charted at 3 3/4 fathoms.
1307 J
First of 5 distant bombs, followed very much to our surprise by a fairly loud depth charge, about 600 yards away.  Q were at 80 feet at the time, and I do not believe we were seen.  Continued to castward to get clear for surface.

Surfaceed.  Raised southwest, running east of IURIL2S, about 10 miles offshore.  Persistent SJ contacts at ranges of 1800 to 6000 yards, acting very much like plane pips.  If those were planes they may have had some sort of search equipment, but nothing capable of directing an attack.  One of these pips showed up on the SD, and I go on record as having not the slightest idea of what they were.

U.S.S. TAUTOG - REPORT OF 11th PATROL

After considerable shouting at our 20-MM gunner, who wanted to shoot a Jap on lift raft who was shaking his fist at us, we managed to spray his deck with about a dozen rounds, whereupon the 20-MM jammed. This kept them ducking until we were safe astern of him, having passed about 300 yards from his fantail. Numerous explosions started off about this time. He was quickly lost in fog, and at 4-

While still about 20 miles from coast of RUSHII, made radar contact on ship at 36,000 yards! (ship contact 7). He was headed north, close in to beach, making 10 knots, and he was about 75°. Bright full moon, 7 to 8 mile visibility. Starc'd 4-4ngine and-c-roud for position ahead for submerged approach - a hopless cause if he rounds SIRIYI. SAI and heads in toward RADIO, but we cannot get in on flank on a night like this. If he is going to HURORI we will have a good chance at him.

Target rounding SIRIYI. SAI light, finally settling on a course of about 270°. This put us about his beam. He could not reach attack position if he was headed into TSUGU RUSTI. If he was merely hugging the beach and going to HURORI, he should have to round SAI S.KI in a few hours, so we proceeded to that point for rest of night and submerged patrol on following day. SIRIYI. SAI, OI. SAI and S.S.I. Lights are all burning at reduced brilliance. We were within about 7 miles of SIRIYI. SAI without any evidence of the "probable radar station" reported on that point. Radar contact at 1,000 yards on ship apparently headed out of TSUGU RUSTI and beginning to round S.S.I. (ship contact 8). From pip size do not believe he was our former target. We were about 7 miles east of S.S.I. Sent to four engines for position ahead. Sighted target, a small to medium freighter, at 12,000 yards. ...t 0318 J we lost him in land jips of S.S.I. sight, though he could still be seen. Full moon in the west and dawn breaking in east made cancellation in air-ground visibility, and there was insufficient time before daylight to reach firing position on surface. Target never did clear the land jips; he evidently rounded the point instead of heading up to HURORI.

U.S.S. TUTOG - REPORT OF 11th WAR PATROL

(I) MINES
Several excursions well inside 100 fathom curve were made, without noticeable ill effects. Small craft appear to run freely at varying distances from the coast between SHIRIYA, S.KI and TODO S.KI. Do not believe there are any mine fields along this stretch of coast.

(J) ANTI-SUBMARINE TESURES AND EVASION TACTICS
There was no evidence that enemy sound gear had us at any time, and no definite attacks were made. The four fairly close charges which followed the attack at KURO S.KI were probably dropped at our firing point. Flare patrols appear to have increased in the KURILES. Numerous sampans, whether intentionally or not, certainly get in the way of attacks on coastal shipping, but they don't seem to see or hear very well.

(K) MAJOR DEFECTS AND DANGER
None.

(L) RADIO
Reception was satisfactory. No serials were missed.

(M) RADAR
The SJ'radar was exceptionally reliable and free of troubles. The SD, while apparently working properly, just doesn't manage to pick up planes. Its present location in the radio room is considered unsuitable for a proper watch, and it is intended to relocate the screen in the control room during the forthcoming refit.

(N) SOUND GEAR AND SOUND CONDITIONS
The JP turned in a beautiful performance, especially when ship was running silent. Sound conditions in areas 1 and 2 were frequently good, but apt to be erratic.

(O) DENSITY LAYERS

U.S.S. LUCY - REPORT OF 11TH FLEET PATROL

(R) HEALTH, FOOD, - 1D - 1BIL. QUALITY

Health was excellent, despite long, cold and clammy all-day drives. Three men suffered cuts requiring sutures; nothing else required more than the usual pill-rolling. Food was good. Habitability is not too good on 16 hour drives in cold water. Rebreathers cannot be used because of the need for conserving the battery, and oxygen is not noticeably short by the end of the day. Heavy weather clothing as issued is satisfactory except for the leather mittens. These are not worn even when dry, and once wet they stay soggy for the rest of the watch.

(Q) PERSONNEL

(a) Number of men on board during patrol 70
(b) Number of men qualified at start of patrol .43
(c) Number of men qualified at end of patrol 51
(d) Number of unqualified men making their last per. of 12
(e) Number of men advanced in rating during patrol 25

The present personnel situation is considered to be satisfactory - or at least still well short of the alarming stage. It is not believed that submarines should consider themselves altogether above the problem of training a few substandard men. A far more important factor than the average ability of our new hands is as high as it is.

The present personnel situation is considered to be satisfactory - or at least still well short of the alarming stage. It is not believed that submarines should consider themselves altogether above the problem of training a few substandard men. A rare fortunate that the average ability of our new hands is as high as it is.

(U) RELL-RKS

Shipping in areas 1 and 2 is still routed within one or two miles of the beach, as reported in J.I.C.P.O.... 38-44. However we observed no indications that it is accompanied by escorts only to a point 15 miles south of SHIRIY. S.M.I. This stretch of coast is so cluttered up with scampas that it is difficult to determine the escort system used, or which vessels were patrolling and which were fishing. In either case, a string of small craft some six miles off the beach provides fairly effective protection for close in-shore shipping.

Considerable shipping passes S.S.M.I. Much of it is of insufficient size for torpedo attack, but as all UURORAM shipping scans to pass this point, a worthwhile freighter should show up now and then. To get at these, a patrol must be maintained within 2 or 3 miles of the point. Targets are extremely difficult to see against the back-ground of SS.M.I.

on assigned track.

Rejoined POMRET.
Fired 5 rounds fire gun for training.

Moored Subase, MAW, 'Made voyage repairs; received
14,455 gallons fuel oil.
Underway. Proceeding via great circle route to TODO
SAKI, HOSHU.

Commenced patrol about 6 miles off TODO SAKI.
Dove 4 miles off TODO SAKI.
Sighted small trawler inshore of us.
Sighted tug with large flat barge in tow, south-
bound along coast. A patrol boat was astern of him,
and remained off TODO SAKI after tug had passed the
point.
Sighted north-bound empty engine-aft freighter pass-
ing TODO SAKI, zigging and accompanied by pinging
escort.
Fired 4 torpedoes from bow tubes, with gyro angles
near zero, torpedo run 3,000 yards in glassy sea. A
look just before first torpedo due to reach track
showed target had turned away. No hits. This
excessive torpedo run was caused by his turn away
after rounding the point. Sent deep to avoid, but
escort never came very close, so at
Came to periscope depth. Heard five depth charges
while raising periscope, and look showed escort.

Foggy at dawn. Continued on surface toward O SHIMA.
Fog lifted. Dove 6 miles east of O SHIMA. Sighted
3 small craft during day, running past O SHIMA.
Surfaced. Patrolled from O SHIMA to MIYAU SHIMA
during night.

Dove 5 miles northeast of O SHIMA. Ran around north
coast of the island. Sighted 4 small craft and one
tug with tow during day.
Surfaced west of O SHIMA. Ran south along shipping
route during night.

Picked up SJ interceptance.
Radar contact at 7,000 yards in direction of interference. Assume to be U.S. Submarine, probably
GABILAH. Interference persisted throughout night.

Dove.
Sighted U.S. submarine on surface on southerly course.
Probably GABILAH.
Surfaced. Returned to own area.

Dove 5 miles off HACHIJO SHIMA.
Sighted small freighter against island, angle on bow
90° starboard, range 9,000 yards. Unable to get in
for shot. At least he indicated the shipping lane
north of HACHIJO SHIMA, but it took us several hours
to get over the range against 2 knot current. Four
sampans were contacted in this lane during remainder
of day.
Surfaced. Patrolled north of HACHIJO SHIMA during
night.

Made battle surface. Seas made gun platform wet and unsteady, but finally after 21 rounds of 5", the vessel was burning-briskly. She replied at one time with a few ineffective bursts of machine-gun fire. After about 15 minutes her small-arms ammunition started popping off, and shortly thereafter an explosion blew off her stern. "Sent alongside a swamped lifeboat to pick up a prisoner." All five survivors hanging on to it came aboard. Two had extensive, though mostly superficial, wounds from fragments. Two others were fairly old. Decided to retain the best specimen and put the others off at TORI SHIP. Our original prisoner is by now a fair interpreter; through him we found that the sampan was the HOKURU MARU, carrying cocoanut oil from the BONINI ISLANDS to TOKIO.

July 20
0045 I Put off 4 prisoners in our rubber boat, 2 miles from harbor at TORI SHIP. Deve south of SII. U SHIP. ROUTINED torpedoes. Surfaced.

July 25
Patrolling submerged in Area 5-B.

July 26
Patrolling submerged off KAMTORI SAKI. Sighted about 25 sampans, 1 PC, 5 small coasters and 3 planes during day. Only possible target was one SHUSU MARU type (about 1,850 tons) heading down coast in light condition. Did not shoot, as we had already water 7 torpedoes on such targets. Surfaced. He had found a close-in patrol in Area 5-B a difficult matter, as this area touches only one point of coast.

July 27 - 31
Patrolling in Area 5-B, submerged during day.

August 1
Patrolling submerged off IRAKO SUIDO. Sighted nine sampans, three trawlers or small coasters, and one plane.

0730
In position, about 3 miles off MIKI SAKI. Sighted ship heading up coast. It turned out to be a medium tanker with one escort, with a smaller freighter and another escort about two miles astern, and slightly further from beach. Unable to get closer than 280 yards to tanker, so let him pass in hopes of a better shot at freighter.
1534
Fired 3 torpedoes from bow tubes at freighter, 800 yard range, 90° starboard track. Target completely obscured by which smoke after first hit, and second hit raised a column of black smoke. Escorts headed our way.
1538
First depth charge. Smoke had cleared and target was not in sight. Consider him sunk.
1540
Vent deep. During following hour escorts dropped 23 depth charges, alternately, and one at a time. All were loud, and some close enough to rattle things a bit, but escorts did not seem to have definite contact on us.
1746
Two distant depth charges. Periscope depth. All clear.

Sighted small engine-aft in extreme light loading headed down coast, making radical course changes. At 1300 we were in position 3500 yards ahead of him, when a zig put us 3500 yards on his port beam. Ran at full speed, off and on, for forty minutes, waiting for him to zig back, but he never did.
1926
Surfaced. Full moon and unusually bright night.

August 4
0137 I
Six minutes after we had made a 40° change of course to the right, four well-defined torpedo wakes passed ahead, on about a 140° port track, about 50 yards apart.

GUN ATTACK NO. ONE
TELEFITI PATROL
9 July 1944. Lat. 43°06'N, Long. 144°08'E.

Target data: - Damage Inflicted

Sunk - One 100-Ton trawler (EU).....

Damage determined by visual observation - the deck was awash, bridge burning and target in a rapidly sinking condition.

Details of action

1. Trawler at anchor was picked up by radar in thick fog. Made approach to pass about 200 yards abeam. Opened fire with forward 20 MM at about 550 yards, and with after 20 MM when it came to bear. Two such passes were made, after which target was circled, and the 5" gun manned. The second round of 5" misfired (apparently due to faulty ammunition, as the firing mechanism was found in good working order), and anyway the telescopic sights were useless in the thick fog. Open sights are not installed. Continued firing with 20 MM until target was in sinking condition. Expended 900 rounds. The trawl had nets out; we occasionally had to back clear of these.

1710. Date: 19 July 1944. Lat. 31°30'N, Long. 140°E.

Target Data: -- Damage Inflicted

Sunk: One 200-Ton coaster (EU).

Damage determined by visual observation. The target was left in a badly burning condition and sinking by the stern.

Details of Action

Battle surfaced at 4,000 yards. Opened fire at 2,000, Twenty-one rounds of 5" ammunition were expended at ranges of from 1,000 to 2,000 yards. Twelfth round started a fire which burned throughout the action and later caused an explosion which blew off the ship's stern. The 50 cal. operated well while expending about 200 rounds. The 20 MM performance was disappointing in that in loading the second magazine of the after 20 MM, a cartridge was ruptured, spilling powder on the entire bolt group and lodging a projectile in the barrel. Before another gun could be brought from below the action was over. In assembling the forward 20 MM in the heat and excitement the barrel was not put in correctl... Target returned fire with machine gun, but his fire all ...ll short.

Remained in vicinity for about 45 minutes; after "Cease Fire", picking up survivors and observing target, which was left in a definitely sinking condition.

Subject: U.S.S. TAUTOG (SS199) - Report of War Patrol Number TWELVE.

1. The TWELFTH war patrol of the U.S.S. TAUTOG, conducted off the eastern coasts of HOKKAIDO and HONSHU, was of 52 days duration. 32 days were spent in the assigned area.

2. On July 6th, the first day in area, four torpedoes missed an AP/AK with single escort off TODO SAKI. Firing range was 3000 yards, 107 starboard track, gyros 2 degrees right, depth setting 6 feet. The enemy ship turned away during torpedo run probably after sighting the torpedo wakes in the glassy calm sea. The escort dropped four distant depth charges.

3. In the morning of July 8th in foggy weather TAUTOG conducted a day-light surface radar attack on the MATSU MARU enroute TOKYO to MURORAN. Three torpedoes were fired from the bow tubes, range 1800 yards, zero gyro angle, 90 starboard track, depth setting 6 feet. One hit stopped the target. The fourth torpedo, fired 14 minutes later, sank this ship. One survivor was taken aboard.

4. Shortly after noon on July 9th a fishing sampan with nets out was sunk by gunfire at close range. Contact was made by radar in dense fog.

5. In the afternoon of July 10th in a periscope attack, three MK. 18 torpedoes were fired from stern tubes at a small AK passing ESAN SAKI, range 1600 yards, 120 port track, 35 left gyro angles, depth setting 6 feet. All torpedoes missed probably due to target speed error. The target was obscured by fog during most of the approach necessitating a quick firing setup.

6. On July 19th TAUTOG battle surfaced and sank a 200 ton trawler by gunfire in the vicinity of SIMUSU SHIMA. Five survivors were picked up. The next day four of these prisoners were put off in a rubber boat 2 miles from the harbor at TORI SHIMA. The best specimen was retained on board.

7. TAUTOG was unable to reach firing position on a medium freighter rounding MIKI SAKI on August 2nd. Later that day a medium tanker with one escort and a freighter with one escort about 2 miles astern of the tanker were sighted northbound. The best firing position that could be obtained on the tanker was unfavorable so TAUTOG shifted attention to the freighter. Three torpedoes were

Subject: U.S.S. TAUTOG (SS199) - Report of War Patrol Number TWELVE.

fired from the bow tubes at the freighter, range 800 yards, 90 starboard track, small right gyro angles, depth setting 6 feet. Two hits sunk this freighter. TAUTOG was ineffectively depth charged for two hours.

8. A small AK sighted August 3rd making radical zigs could not be closed for attack. During bright moonlight on August 4th four clearly defined torpedo wakes passed ahead of TAUTOG 6 minutes after she had made a 40 degree course change to the right.

9. With the exception of one freighter and one medium tanker all enemy ships contacted on this patrol were small. Numerous sampans and patrol vessels frequented the area. There were twelve aircraft contacts in the area. It must be expected that enemy submarines will conduct submerged patrols during bright moonlight in areas close to his shores.

10. The TAUTOG is being sent to the west coast for overhaul.

11. The Commanding Officer, officers and crew are congratulated on the damage inflicted upon the enemy during this well conducted and aggressive patrol.

**USS LUCY - Report of Patrol in War Patrol**

- **About 4,000 yards from us; and soon passed out of sight. Resumed approach on smoke, now seen to be issuing from an unescorted freighter similar to the UCU SHIP, angle on the bow zero, tracking at 9 kts.; on steady course. Nothing sweeter could be desired, until she changed course about 60° to head down east of MIRSUKI SHIP, leaving us well off her track.**
- **Tired. 4 Mark 18's from bow tubes, near O cyros, 120 starboard track, torpedo run 2,500 yards. To hits. 'With much disgust watched her calmly run on in to USSHIP. At still unaware of our presence. At least we learned that this passage is used, and hope to profit thereby.**
- **Surfaced.**
- **Radar contact on several closely grouped small craft, range 5,200 yards. They tracked at about 12 knots on southerly course. Voiced.**
- **Sight contact on lighted ship. Closed and identified as properly marked hospital ship, course 252°T, speed 8 knots, evidently starting out for SHIP. It is unfortunate that the Geneva Convention had nothing to say about radar; we had good indications that this fellow has it: 92 mcs., on a steady sweep.**
- **Proceeded to point for submerged patrol. Radar contact on several large ships well down the funnel toward SISSO. Believe they are waiting until drawn to enter, as they seemed to mill around and then head southward. Turned to close,**
- **Dove. Continued south for two hours without sight contact on anything.**
- **Sighted small sampan. Sighted ship proceeding along coast of AUGUST SHIP, heading northeast. Good identified as a DE-UI-1, which passed by at 3,000 yards, speed about 16 kts. Sighted at No. 7 type, heading in to SISSO at 18 kts. These 2 vessels, plus yesterday's submarine, seem to be going between SISSO and the SEA OF JAPAN, where they probably train.**
- **Surfaced. Patrolled along SISSO - SHIP route.**

**Jan. 12**
- **Before dawn dive ran into funnel between MIRUDSHIP, and UKU SHIP, where yesterday morning's contacts were made. All clear.**
- **Dove.**
- **Sighted smoke and funnel of freighter emerging from other (south) side of AUGUST SHIP, on easterly course. He are on his beam, about 8,000 yards distant. While trying to close him, we sighted today's DE, breezing by at 4,000 yds., heading for SEA OF JAPAN.**

1.302 Freighter, having passed north of KUTSUKI SHIMA, headed south toward SASEBO.
: 1350 Sighted small trawler.
: 1710 Sighted tops of freighter heading out of USUMA. Instead of coming on out he ducked into OSIMA SETO. He tracked at about 15 kts. Increased speed and headed east on the slim chance of picking him up on surfacing.
: 1828 Surfaced 6,000 yards north of AZUCHI O SHIMA. Radar out of commission!! Reversed course.
: 1910 Radar back in commission. Patrolling southern end of HIGASHI SUIDO. Shipping has been routed every possible way through these islands, and always in a way to frustrate us.

Jan. 13
: 0634 Dove off ULU SHIMA. Several sampan contacts and one on our SCS-1 type patrol vessel during day.
: 1830 Surfaced.

Jan. 14
: 0633 Dove north of AZUCHI O SHIMA. Ran along shore to eastern end of island to try to get at the shipping that has been going through O SHIMA. SIGHTED numerous sampans and several steam trawlers during day. These would often make smoke visible over the horizon, and in chasing one such contact we were drawn about 4 miles to eastward of the island, just in time to miss a chance at a medium AK sighted, distant 10,000 yards, proceeding up east coast of island, with our scuttle 7,000 yards off his track. TO escort; only air cover of one small float plane.
: 1427 Surfaced. Heading into heavy seas to make rendezvous with SILVERSIDES.

Jan. 15
: 0200 Radar contact on SILVERSIDES. She had some dope to pass by line-throwing gun, but weather too bad to get one across. Exchanged some information by VHF, and then swapped patrol areas.
: 0633 Dove off OSE SAKI.
: 1824 Surfaced. Seas too rough for firing, so ran southeast to patrol in lee of KOSHIKI RETTO.

Jan. 16
: 0528 Radar contact at 17,000 yards. Target tracked on course 180 for about 15 minutes, then changed course to 270°, where he stayed at 10 kts. speed. Insufficient time to attack before daybreak on surface, so worked out to position 12,000 yards ahead of target, and at Dove. Seas force 5.
: 0635 Sighted target - a DE-UH-1 type, similar to the one shown in ONI-222J, except that stack was abaft mainmast. Since we dove he had changed course to about 320°T, leaving us about 5,000 yards off his track, but it was too rough for a shot at such a shallow draft target anyway. Patrolled between SHIMO KOSHIKI and NOMA MISAKI for rest of day.

Tired 3 torpedoes from stern tubes, near 180° gyros, 90° - 110° port tracks, 650 yard run, fired at 120°, bow, and stern. #1 hit, blowing off bow from bridge forward and stopping target. #3 should have hit did not; that was left off target (later identified as loaded XPD, identical with USS KUSHI's) refused to sink, so circled and at

1339
Fired #2 tube with 0° gyro, 700 yard run. Hit. Target disintegrated into high-flying debris and a column of smoke several hundred feet high.

1358
Sighted SOS-1 type patrol boat heading toward scene of sinking.

1459
4 depth charges, about a mile distant, evidently dropped by planes.

While docking these patrol boats, suddenly sighted TRAUTSUKI class destroyer, distant 3,500 yards, with a near 90° angle on bow, making 18 knots. Too late to do anything about it.

1847
Surfaced with 2 lighted fisherman distant 4,000 yards. Ran west toward SHIMO TO.

2306
Sighted bright red light, identical with that on our hospital ship the night of the 11th. He tracked on course 090. While tracking him, at

2318
Made radar contact on another single target, making 10 knots, and zigging with short legs on base course 130°T. Sighted him at 10,000 yards in the bright moonlight, but we had a dark background behind us.
