Detonated convoy to consist of eight ships escorted by five destroyers and two or more escort vessels. Three destroyers in the van, one on each quarter with escorts aboard of convoy, all jettrolling but not echo ranging. Three successive zigs placed van escort or destroyer aboard with zero angle on bow. Sent 300 yds astern of escort making approach on 6,000 ton maru. At this point convoy zigged right en route trailing destroyer commenced to pull ahead - 15° angle on bow at range of 3,000 yards.

Discontinued search of area and commenced search along estimated base course of escort.

0433
Nothing seen of escort so reversed course.

0540
Sighted two columns of smoke on horizon. (Position Lat 19-35N Long 114-57W). Those were probably same ones seen last night. Commanded and around run to gain position ahead.

0737
Sighted plane (aircraft contact #10. Lat 19-25N Long 114-22W) ahead of convoy which turned and headed for us, drove. At this time it is estimated that we were just forward of convoys beam and about 10 miles from track so decided to stay down clear of plane and close track.

0545
Canoe up for look and found destroyer broad on port bow at range of three thousand yards. Destroyer turned and gave us zero angle on bow so assumed he had sighted us. Received no depth charges but on three attempts to come up during next four hours picked up high speed score's close aboard when passing 150 feet.

1450
Surfaced and headed down estimated base course.

2000
Sighted three ships dead ahead, range about 10,000 yards. Radar out of commission. Decided to get in position to approach and trail convoy till radar was ready.

2208
Had all-ride range to close to about 7,000 yards when destroyer escort entered.

2212
Destroyer came out of rain squall with zero angle on bow and increasing speed. Made radical change of course at high speed and lost him. I think he had radar but that its effective range on a submarine was only about 7,000 yards.

16-01-1944, U.S.S. T-30R - RIZOR OF THE R-REPUBLIC

(L) R.DIO

On 16-01-1944, four unsuccessful attempts were made to communicate with the boat, but 06002 and 14002. The message was sent blind on 8470 no. 4235 to 14332 but was evaded, not received.

Again on 31 May 1944, could not be received at 0300, but the message was received at 1000. Three other messages were received promptly and with no trouble while in assigned area.

There was a report to account of the interference on the first schedule on night 27 May, but other interference was satisfactory.

(1) R.DIO

The action of the destroyer escorting the convoy on the night of 27 May indicated to us that the enemy was not in readiness to attack our convoy.

The planes encountered on the night of 27 May had either R-1 or R-2 cruiser miles outside the convoy.

This is the second patrol with the new transmitter and a general improvement of the ship's ability to communicate with the fleet. The modification not only installed a new ship's radio, but also improved the range of the radio. Failure of the radio was due to the loss of oil due to leakage. One unit was sent in operation by sole carrier to the fleet.

The increased power required by the new transmitter caused the motor gear to start out to run hot and the installation of a cooling fan is being requested during current refit.

(2) R.DIO

The carrier was 5D on this patrol and a modified improvement over last patrol, minimum range 22 miles, minimum range 7 miles.

1. PRESENT OVER: 1. USS. T. BOR - REPORT OF TENTH YEAR 2. ATLANTIC

(Q) PERSONNEL:
At present over fifty percent of the crew have two or less war patrols. Daily school and drill has made it possible to keep up the operating standard of the past. The vanishing of men with extensive submarine experience is however being felt more and more. The loss of these experienced men is proving a decided handicap in effecting repairs while underway. The willingness to work and learn displayed by the new men cannot be effectively substitute for the detailed knowledge of machinery and trade skill of our pre-war submarine men.

Subject: U.S.S. T-BOR - Report of T-BOR Patrol Number TEN.

1. The tenth war patrol of the T-BOR was of fifty-seven days duration of which thirty-five days were spent in the assigned areas. Area coverage was excellent.

2. In the early part of the T-BOR made contact with an enemy trawler at morning twilight and destroyed it by gunfire. There were four contacts worthy of torpedo fire of which two were developed into successful attacks. Of the two contacts not developed, one was a smoke contact which occurred while the approach for attack number two was in progress and the other was thwarted by persistent and effective aircraft and destroyer activity.

3. GUY ATTACK NUMBER ONE - T-BOR sighted a 250 ton wooden trawler at 0530 at a range of 10,000 yards and immediately closed for gun attack. Fire was opened at 8,000 yards and T-BOR continued to close range until counter fire commenced to straddle. Firing with deck gun was continued until enemy fire was silenced at which time range was closed to point blank and target was raked with 20 mm fire. Target was then bombed and papers and one prisoner, the second officer, removed. Seven other crew members were killed. Target was left in a sinking condition with only the top of bridge and pilot house above water and on fire.

TORPEDO ATTACK NUMBER ONE - A cay periscope attack on a convoy of eight AKS (possibly one an oiler) escorted by five destroyers and two or more smaller escort vessels. T-BOR penetrated the screen and fired four bow tubes at a large unidentified AKS, range 1600 yards on a 950 port track. There were two timed torpedo explosions followed by another very loud explosion. T-BOR went deep and after a total of fifty depth charges, surface and returned to the scene of attack where one destroyer and one escort vessel were observed searching the area. A large oil slick, debris and life ring lights were noted.

TORPEDO ATTACK NUMBER TWO - This attack was a night radar attack on a diesel freighter escorted by one patrol vessel. Target was sighted in mid afternoon and T-BOR made an en-arrow run to gain position ahead for a night attack.

0439 Surfaced on course 0350T.
: 1510 c/c to 2150T.
: 8 August
: 0320 Made trim dive.
: 0335 Surfaced on course 2150T.
: 1408 Sighted smoke of several ships bearing 3000T.
: 1412 Submerged for periscope approach.
: 1600 Sighted masts of about 5 ships at range of about 10,000 yards, angle on bow about 50° starboard. Closing track at 6 knots. Convoy zigged away, presenting about 110° angle on bow, and disappeared in rain squall. Saw one tanker, two AK's, destroyer and smaller escort. Destination probably PaRusSHIRU, base course about 0800T, speed 8 knots.
: 1745 Surfaced for end-around. Started chase on four engines. Maintained contact by sight and radar; visibility variable, radar unreliable. PFI out of commission, A-scope began giving trouble. During end-around two engines had to be secured because of piston seizure and cracked liner. Decided that twilight periscope approach was only feasible method because of SJ failure and speed limitation.
: 1930 Submerged 13,000 yards ahead of convoy on base track. Sunset at 1924. Good twilight has been lasting up to 13 hours. During approach, visibility decreased to about 7500 yards.
: 2000 Sighted outlines of several ships, picked out what appeared biggest and came in for attack. Range about 4,000 yards, angle on bow 400 port, bearing 3000 relative. Came left for 900 port track, bow shot.
: 2005 Sighted destroyer on starboard quarter, range about 2,000, angle on bow 500 starboard. Decided to fire stern tubes at DD, since original target could not be made out in reduced visibility at this time.

2010
Destroyer showed 100° angle on bow, range 1400, started pinging. Decided we had been picked up by sound, so went deep. Destroyer passed over us to port side, stopped, and ceased pinging. We got under a 100° negative temperature gradient so it is doubtful if he ever had a positive contact after we went deep.

Commenced repairs to SJ radar.

2255
Surfaced. Repairs completed. Commenced pursuit of convoy on course 0750° on engine power available. Convoy speed was 8-9 knots. Put one generator on battery charge from 2330 to 0250 and made 12 knots on one generator. Started repairs to remaining engines. In view of last night's casualties to main engines, decided not to load remaining engines over 80-90 speed.

9 August
Continued pursuit of convoy.

0250
Increased speed to 14.5 knots.

0333
O.O.D. and lookout reported sighting periscope 800 yards abeam. Avoided. Continued chase until 0900. At this time we were 40 miles from PARAMUSHIRO TO. Plot showed us to be at least 25 miles ahead of convoy on original base track. Contact was not regained and chase was abandoned.

: 1030 Radar contact at 13,000 yards. Visibility about 2,000 yards. No. 3J radar interference or indication by radar detector. Commenced tracking. Pip on radar appeared too big for submarine. Ship was making 6 knots on course 240°, which is general track from PARAMUSHIRU to La PATOUISSTRAIT. Decided to come in for attack position and close until able to identify. Made tubes ready forward and closed on 1050 track.
: 1136 At 2,000 yards range sighted target dead ahead as fog lifted like a curtain. It was a medium freighter. No Russian markings.
: 1137 Fired 4 torpedoes set at 10 feet on 90° starboard track. as last torpedo was fired, submerged. Heard 2 explosions while leveling off at periscope depth. Came left and watched target lower 12 lifeboats and then sink. Heard 2 end of run explosions. Took pictures. Visibility by 1200 was almost unlimited. Ship sank in 20 minutes. Torpedoes left a good trail of smoke.

Surfaced. Prepared to take prisoners from lifeboats.

1230
Lookout sighted 2 more ships. Put them astern and commenced tracking.

1240
Sighted ship dead ahead, range about 14 - 15,000. Identified as escort vessel - similar to PG-E-1 class gunboat. He sighted us at about same time and headed for us. Put escort astern and cleared at flank speed. At this time we were still several thousand yards from the survivors. Escort probably sighted our high periscope and thought we were the sunken ship. Expected him to pick up survivors, which he seemed to do, as we opened out easily after he reached the vicinity of the lifeboats. Also, lookout reported possible gunfire and searchlight blinking. The other ships were now out of sight. He had a quick check on their course - about 240°, the same as the vessel attacked.

1315
Came to course 270°T to intercept track of targets. This seemed to be a convoy attempting to form up after being scattered by fog.

0600
Submerged for periscope approach. At first determined ship to be on course 060°, range about 15,000. This would have been ideal for submerged approach, but he was actually on the old 035° course for PARAMUSHIRO. Closed to 10,000 yards and determined ship to be tanker.

: 0814
Surfaced for end-around. This time the engines held up and put out 19,5 knots. Tracked tanker by heavy smoke and occasional glimpses of stack and superstructure. Speed 11, on steady course 040°.

: 1343
Reached position ahead of target and submerged for approach. Ship appeared to be a large tanker, with high stack. She smoked continually, and steered a steady course and had no escorts. Also, she appeared to be light, with about 12' of freeboard.

: 1440
Fired 4 torpedoes on 90° starboard track, range 2,000 yards, gyro angle 9L to 4R, depth 6 feet. Watched one torpedo breach near target. Torpedo made a large splash in line with target's screws. Thought this was a sure hit but heard no explosion. Then saw broaching torpedo pass about 100 yards astern of target.

: 1445
Target turned toward us. Came left and went deep.

: 1447
Heard 4 torpedo explosions.

: 1500
Came to periscope depth. Tanker was still belching smoke and had changed course to 340°, range about 11,000.

: 1520
Put target astern and surfaced.

: 1522
Headed for target, intending to trail and attack at night.

: 1532
Tanker opened fire with guns. Range about 14,000. Gun flashes looked pretty large, so submerged. While at 50 feet, saw flash of gunfire, then an explosion 1,000 yards abeam of target.

Reloaded torpedoes and repaired 3U radar, which again is failing at a crucial time.

Believe we missed target because of excessive spread used. A few hundred yards error in range would give excessive percentage of coverage and target could avoid.

ENCLOSURE (A) -11-

— page 37 —
1850
Target had been tracked for some 5 to 6 hours while on steady course and speed. Firing range was long, but sea was calm and there were no white caps, so considered this a good range. Torpedoes did not seem to smoke excessively as in previous attack.

Considered possibility of Russian nationality of this vessel, but was no identifying markings, although we could find no similar tanker in Jap identification manuals.

1850
SJ radar repairs completed. Surfaced on course 3150T. Headed for coast of SAKHALIN. Decided not to pursue further into POLYPON area.

1) MINES
No information.

(J) ANTI-SUBMARINES MEASURES AND EVASION TACTICS
No anti-submarine measures were encountered. The destroyer escorting the convoy on 8 August detected us probably by listening. Its turned toward, started pinging and passed over us, but did not attack.

(K) MACER DEPOTES AND CHARGES
Auriliary engine out of commission since 7/22, due to defective blower with it could not be repaired by ship's force.

#1 and #3 main engines suffered a total of 5 unit failures due to piston seizures and cracked liners.

(L) RADIO
Radio reception was excellent throughout the area. HAIKU FOX schedules were copied clearly on 9090, 6380 and 14750 Kcs. and reception of programs from the U.S.A. on the REO was good. No enemy interference was experienced except during the President's speech from the west coast when deliberate CW jamming made reception impossible.

There was no definite radar interference on AFR although a signal was received at 610 Kcs. which was traced to our SJ radar.

Transmission on 8470 Kcs. to NPM was very good and no difficulty was encountered.

Operation order directed us to guard 4475 Kcs. the lifeguard frequency, NPM, and the area frequency. While we were on station the area frequency was changed from 450 to 2880 Kcs. as only two RAL receivers are installed we were able to guard only two high frequencies simultaneously.

3. (M) RADAR
4. A. SJ-a
5. The SJ radar gave generally poor performance during the patrol. Had it been in service on 8 August, we would have been enabled to trail and attack the convoy at night. Our efforts at a twilight submerged attack having been frustrated by the escort, we remained submerged until the radar was repaired and lost contact. Soon after the attack on 13 August, the SJ again had to be put out of commission for repairs. Navigation of the KURILE Island straits is a simple matter with radar, but at this season the continuous fog makes it nearly impossible without radar. Continuous operation of the equipment in damp atmosphere may, in part, be responsible. Ranges obtained while the equipment was operating were good. Maximum ranges obtained were 95,000 yards on land and 15,000 yards on a medium AK.

The following detailed troubles were experienced:

(a) No sweep on PPI - C-16(shorted) and 616 in PPI unit replaced.
(b) No sweep on PPI. Replaced F202.
(c) Ranges low. Replaced magnetron.
(d) Lost high voltage. Replaced two 636's in rectifier unit.
(e) No sweep on Range-Indicator. Replaced C-35(shorted), 2K-2, and 1P1 - 1P4.

(M) RADAR (Cont'd)

(p) Line voltage meter defective. Believed to be indirectly responsible for intermittent grass trouble. During training at Midway, considerable trouble was caused by oil leaking from the modulation network, two networks failing. After a 4" copper tubing vent line was installed to relieve the pressure, no further trouble was experienced from this part.

The intermittent trouble causing loss of gain on the A-scope and PFI developed about the third week of the patrol. Although several faults were discovered which improved this condition, the actual cause was not found until near the end of the patrol and is believed to be a defective line voltage motor.

The modification of the SJ for recognition was completed on station.

50-watt lamps were installed as heaters in the Range- Indicator, PFI, and Transmitter-Receiver. These were taken from the same fuses supplying the Range Unit heaters and were kept lighted during the time the equipment was not in operation.

B. SD=4

The operation of the SD radar was satisfactory.

(N) SOUND GEAR AND CONDITIONS

Sound conditions were poor throughout the area. High noise levels were frequent and unusual noises often resembling screws were heard. These were attributed to some type of fish. At 2500 yards the J-K-QC failed to detect the screws of an A.O. The only material casualty was the jamming of the mechanical limit stop on the J-K-QC gear upon the failure of the electrical limit switch. The mechanical stop was removed and the electrical switch repaired.

(V) REMARKS (Cont'd)
Of the two convoys sighted, the first, on 8 August, apparently followed the coast of SikkhalIN north to latitude 50°N, longitude 145°E, then crossed the Sea of OKHTSK on course 080° to PARAMUSHIRU. The second convoy, sighted on 15 August, followed the general route from PARAMUSHIRU to La PEROUSE Strait on course 230°, and passed through 48°29'N, 147°49'E.

The only vessel in identification manuals that can be found similar to the destroyer seen is one STEAMART class. One escort of the PG-E-1 type was seen with the second convoy. Believe he made about 15 knots while chasing.

Via: (1) The Commander Submarine Squadron FOUR.
(2) The Commander Submarine Force, Pacific Fleet.
(3) The Commander-in-Chief, U. S. Pacific Fleet.

Subject: U.S.S. TAMBOR (SS198) - Report of Eleventh War Patrol.

1. Forwarded.

2. The eleventh war patrol of the TAMBOR, conducted off the northeast coast of HONSHU, southern coast of HOKKAIDO, and in the KURILE Islands area, was of 48 days duration, 30 days being spent in the assigned area. This was the first patrol of the commanding officer as such.

3. The TAMBOR made five enemy contacts while in the area worthy of torpedo fire. All contacts were aggressively pursued and all but one were closed near enough to attack. An alert escort prevented firing on the five ship convoy contacted on 8 August, 1944. Three attacks were made which resulted in sinking of a medium freighter and damaging and probably sinking a small freighter or trawler.

4. (a) Attack No. 1. On July 28 TAMBOR picked up radar contact at 5000 yards, visibility 800 yards. After tracking for one hour, the TAMBOR fired three (3) torpedoes on surface at a small freighter or trawler, obtaining two timed hits. The third torpedo was heard to explode four (4) minutes after firing at end of run. Target did not slow down or change course. TAMBOR continued tracking target by radar to close in for another attack; upon reaching firing position radar contact was lost, indicating target probably sank.

(b) Attack No. 2. At 1030 on 13 August TAMBOR picked up radar contact at 13,000 yards, visibility 2000 yards. After tracking for about an hour and a half TAMBOR sighted target, a medium freighter, 2000 yards dead ahead. One minute later TAMBOR fired four (4) torpedoes, obtaining two timed hits; the other two torpedoes were heard to explode at end of run. The target was seen to sink.

(c) Attack No. 3. During early morning of 15 August TAMBOR sighted an unescorted heavily smoking tanker on course for FARAMUSHIRU. After tracking tanker and completing end around, TAMBOR submerged ahead of

Sighted nine layer at 3500 yards bearing 270° relative angle on bow 90° port. (Ship contact No. 3). At first this was believed to be a small patrol vessel and no attempt was made to attack. Subsequently it was determined to be a 1300 ton vessel, however. Favorable attack position could not be gained submerged and under-away was not feasible as he would be in TOXO in 3 or 4 hours.

It 4° 20' 5" 10° 5" 20' 5" and 5° 25' after first torpedo was fired, heard explosions. Target remained on radar sectors as we cleared firing area, and out to 13,000 yards, when it was lost. It is believed that the first two explosions were hits and that target probably sank. The first 2 explosions were accompanied by flashes seen on the bridge. The target was sighted at about 3500 yards range and is believed to be a man of war about the size of a destroyer escort.

First estimate of enemy course and speed showed him to be leading for TONO BAY at 11 knots. Started end-around with about 30 miles between us and SAGAT M.D. Soon was bright and sky clear. Target could be made out at 11,000 yards range. Looked pretty large. After one hour of tracking, target increased speed to 20 knots and left us behind. We closed to a minimum of 9,900 yards during chase. It looked like a cruiser. Chased to within 12 miles of TONO BAY. Believe target picked us up by radar. There were two vessels, one a little larger than the other but only one ship was sighted and tracked. The other ship was several thousand yards farther away on about the same bearing.

1845 Abandoned chase and headed out to eastward. Thus far all traffic sighted has been headed in the direction of TONO BAY. Our patrol station - covering the approaches to SAGAT M.D. - has been in close with little room for chasing on surface.

Fire three air torpedoes from bow tubes on 125" starboard track, average run 2300 yards, depth set zero.

Heard one explosion one minute 15 seconds after first torpedo was fired. Another one minute 38 seconds after firing and the third four minutes 30 seconds after firing.

No hits were obtained. Target knew he was being shot at, nor was he aware of it. He was on a course of 2300 yards, with gunfire as he approached. About 26 rounds of small caliber were fired. It is believed that our first two torpedoes exploded in target's wake or permitted. The third explosion was probably at end of run.

Continued tracking target at 8000 to 9000 yards range. Decided to waste no more fire on this vessel and to make a dawn battle surface.

Went to stations for battle surface. Intended to surface 2000 yards astern of target. A last minute change of course by target nearly ruined the set-up as he headed almost directly for us. However, he took such a course as to enable us to surface 2400 yards on his quarter.

1. RADIO
Radio reception in the area around TOKYO BAY was only fair. Continual jamming by the enemy of the Fox Schooldogs made reception difficult and necessitated frequent frequency shifts. Stagnoside reception was practically impossible throughout the run.

Extremely heavy jamming in the area between the BOMBS and TOKYO caused us to try for several days before being able to work. Definite baggie jamming was experienced several times.

During our short wolf pack operations with BURT'S BROOK, transmission and reception was quite good on the 702.00-1 frequency. Jamming, though not heavy, was encountered.

The only material failures was a ground H.V. motor in the TSL.

(11) RADAR
SJ(a) Radar

Operation of the SJ Radar during this patrol has been highly satisfactory. The only lost operation was 5 hour while the line voltage switch was being repaired.

Definite 10 sq. anony interference was encountered several times in the TOKYO BAY area. This was seen on the scopo as pulses about four times as wide as normal SJ interferance.

Ranges:
Small Island (700')
80,000 yards.
ES (Tracking)
14,000 yards.
C. (fixianum)
38,000 yards.

During wolf pack operations the SJ was used for recognition and communications. The signal was quite readable on the screen and operation was satisfactory.

Material Failures:
L.V. line switch.
Normal tube replacements.

SD Radar

Operation of the SD was normal though the usual low flying planes were detected visually before being picked up by radar.

The SD was keyed 5 seconds on and 30 seconds off enroute to and from patrol area but was not used while in the area.

SD Radar (Continued)
A low current reading was obtained (5 to 7 ma) when the sot was keyed. This condition arose after the last refit and did not seem to materially affect operation.

Material Failures:
- Replaced 3014's No grass
- Replaced 446's

(N) SOUND GEAR AND SOUND CONDITIONS
Operation was normal during this patrol.

- Submarine at about 2000 yards was undetected but this may have been due to the water conditions. Screws from a destroyer were heard at a roughly estimated range of 3000 yards. Loud fish noises, closely resembling screws, were frequent in the area.

(O) DENSITY LAYERS.
Density gradients were normal but no information was obtained as to their degree.

During a depth charging enroute to the area this ship was balanced nicely in the center of a SIX degree gradient.

(2) HEAVY, FOOD AND EMERGENCIES.
(1) Health.
There were two sick days due to fracture, concussion, left tibia and fibula, involving the knee joint. There was one case of suspected G.U. infection outbreak. Slides run were negative. No sick days for this case. Two cases were under observation and treatment for D.U. Catarrial fever. Both responded to treatment in 48 hours and resulted in no sick days.

(2) Food.
Food in general was highly satisfactory, nourishing and varied.

(3) Habitability.
The habitability has been vastly improved by the installation of a booster blower in connection with the air conditioning system forward. No particular discomfort was experienced even though submerged patrol was necessary in area for most of the run.

U.S.S. TLEBOR, Report of TELBOR War Patrol.

(2) The third and fourth torpedo attacks made on the target
later sunk by gunfire were attempted because it was desired to
polish his off as early as possible and resume patrol. The sea was
very calm and weather clear and very dark. Torpedoes were set at
zero depth. It is difficult to explain misses, as set-up in each
case looked ideal. However, one torpedo definitely ran erratic in
the first attack, as the explosion at end of run was soon 90° from
where it was fired. In the second attack, the explosions of torpedoes
picked into the air but did not damage, leading to the conclusion
that they broached or exploded in the wake of the target.

(3) Handling of wounded personnel.

The care and treatment of wounded personnel was in the
hands of REGARDS, R. W., 2th: (....), USNR, T.S.S. TLEBOR, REGARDS
performed this duty in an able and considerable manner. The personnel
function of loss of a leg by our 5th unit trainer was doubtless due
to his constant care of REGARDS and his conscientious devotion to
duty. . . . A letter of commendation has been addressed to REGARDS by
this commander.

In this connection, it is desirable to call the attention
of endorsing sailors to the services rendered this vessel by the
U.S.S. GRAYSON (DD.35), commander of Guard, 7. V. 2R, MT, 2nd, USN.
GRAYSON received our wounded and prisoners and transported them to
the S.L.I.T. This operation was carried out in a moderate sea in a
seamanlike manner which was nothing short of excellent and with
least possible disturbance and discomfort to the wounded. Seas
were too rough for boating and breaches buoy and Stokes Stretcher
was used. The 7th TLEBOR would appreciate some official recognition
of GRAYSON's services. Also, the fact that TLEBOR was
ordered to S.L.I.T. to discharge wounded and a destroyer was assigned
to this task has had a profound effect upon the morale of this
boat. No realize that our interests are important and we appreciate
the inexpressibly the care and attention we have received.

Subject: U.S.S. TAMBOUR, Report of War Patrol Number TWELVE.

1. The TWELPH WAR Patrol of the U.S.S. TAMOUR was of fifty-one days' duration, twenty of which were spent in the assigned area, south and east of SAGAMI NADA, HONSHU, and in a sweep NW to NE of the BONIN ISLANDS. Area coverage was excellent and the patrol was smartly conducted throughout. Contacts which could be developed were as follows:

ATTACK NO. 1 - NIGHT RADAR, SURFACE, 15 OCTOBER 1944

A radar contact was tracked for course and speed. There was one large pip and two smaller pips, indicating a ship and two escorts. One hit for four fired resulted in disappearance of target pip and distinct rumpling noises from direction of target. When contact was regained, only the two escorts were present.

ATTACK NO. 2 - NIGHT RADAR, SURFACE, 19 OCTOBER 1944

A patrol vessel was tracked by radar, and was in sight for about five minutes before firing. Of four torpedoes fired, two were timed hits and from the first hit, a flash was seen from the bridge. Target pip disappeared at range of 13,000 yards.

ATTACK NO. 3 - NIGHT RADAR, SURFACE, 16 NOVEMBER 1944

Three electric torpedoes were fired at an enemy patrol vessel, average torpedo run 2,850 yards, depth setting zero feet. No hits were obtained.

ATTACK NO. 4 - NIGHT RADAR, SURFACE, 16 NOVEMBER 1944.

Forty-one minutes' later, three air torpedoes were fired at same target, average torpedo run, 2,300 yards. Of three explosions heard, two are believed to be premature or explosions in target's wake, and the other an end-of-run explosion.

1-4 NOVEMBER 1944
GUN ATTACK NO. 1 - 4 NOVEMBER 1944

An enemy patrol vessel was attacked by gunfire, approach being made on surface. It was necessary to keep range greater than 6,000 yards to avoid straddles by enemy's gun, estimated about 3-inch. Although target was damaged by several hits and many near misses, TAMOR's 5-inch ammunition was expended before the vessel could be sunk.

GUN ATTACK NO. 2 - 16 NOVEMBER 1944

A patrol vessel of 200-300 tons was sunk by gunfire in an existing gun battle described in detail on page 25 of the patrol report. The 5-inch gun trainer received a painful wound in his leg. Photographs of the vessel were taken and two prisoners were recovered.

It is gratifying to note the full-hearted and efficient cooperation of the U.S.S. GRAYSON in taking TAMOR's wounded man for transportation to California.

TAMOR is enroute West Coast for overhaul. Personnel were in excellent spirits and the ship was very clean. The Commanding Officer, officers and crew are congratulated on an excellently conducted and aggressive patrol. It is recommended that the following damage be credited:

SUNK

1. Unknown (UN) 4,000 tons
1. Destroyer escort (DU) 1,200 tons
1. Patrol vessel (EU) (Gun Attack) 5,500 tons.

DAMAGED

1. Patrol vessel (EU) (Gun Attack) 300 tons.

DECLASSIFIED.
REASSIGNED.

U.S.S. TALOR
e/o Fleet Post Office,
San Francisco, Calif.
April 15, 1943

FROM: The Commanding Officer.
TO: The Commander Task Force 51.1.

SUBJECT: Special Instructions - report of.

REFERENCE: (a) U.S. 51.1 Secret 1st. 16-3 of February 16, 1943.

The original plan of reconnoitering PACDLAN 2AY and daylight patrol and then disembarking party and supplies at a point just west of TURK. After dark was abandoned, Lieutenant Commander Farenos, USNR, believed that LIEUTENANT, the one of the natives, was in the hands of our forces and a detritus contact with them would be much safer. The plan finally selected and used, agreeable to both the Commanding Officer and the leaders of the party, was as follows:

(a) Lt. Condr. Farenos and two natives would disembark in wharf on shore before dawn approximately five miles from LIEUTENANT.

(b) Lt. Condr. Farenos was to land at LIEUTENANT, contact our forces; and arrange for possible means of transporting supplies ashore.

(c) The O was to remain submerged in center 1 vicinity and await return of wharf in the afternoon.

(d) Wharf on the return trip was to fly a white flag all clear and a black flag if landing was inadvisable.

(e) If wharf did not return by 1900, TURK was to proceed to LIEUTENANT and attempt landing of Captain Smith and supplies with rubber boats.

The chronological list of events:

March 4, 1943.
1850 - Surf. cod and proceeded toward PACDLAN BAY.
2000 - Removed wharf skids and lashed it on deck to avoid noisy operation close to beach.

March 5, 1943.
0445 - Arrived four miles southeast of LIEUTENANT. Visibility was poor during night and practically all navigation by 5F radar.

— page 115 —
0517 - Lt. Condor, Parsons and natives left ship in wherry. Submerged and patrolled area.
: 1637 - Sighted wherry flying white flag and proceeded to close it.
: 1645 - Sighted small power launch towing native lighter standing out from direction of Endo, flying white flag and American ensign.
: 1710 - Recognized Lt. Condor, Parsons in wherry. All during day it had seen raining and at this time the beach was practically obscured.
: 1723 - Surf ced and manned all forms of surface armament, 3rd radar and sound equipment.
: 1740 - Wherry, launch and lighter came alongside and commenced unloading supplies in lighter.
: 1830 - Completed unloading stores. Allowed Lt. Condor, Parsons additional half hour to complete his report.
: 1915 - Left area.

4. It is considered that any future landings could be made in like manner and could be expedited if security was sufficient to warrant sending the approximate date of arrival of submarine having it met by small boat flying a prearranged signal.

1. Forwarded.

2. The Commander Task Force SEVENTY-ONE considers that the details for landing the party and its equipment were well planned and that the mission was accomplished in a ex-peditious and efficient manner.

3. On the basis of information as to the scarcity of ammunition in the area, 35,000 rounds of .30 caliber ball ammunition was loaded in the TAMBOOR in addition to the 20,000 rounds of .45 caliber and 15,000 rounds of .30 caliber ball ammunition originally requested. The excellent arrangements for unloading provided by Lieutenant Commander Parsons made it possible to transfer this entire amount of ammunition ashore.

4. By copy of this endorsement the Commanding Officer, officers and crew of the TAMBOOR are given a "well done" for the manner in which this task was accomplished.

18 April 1944.
From: The Commanding Officer.
To: The Commander Submarine Force, PACIFIC WEST.
Subject: Gun action on 18 April 1944.

1. At 0530 (-11) on 18 April in position 22-43 N and 162-44 E, encountered a 250 ton wooden vessel identical with "Orub Tander #10" ONI 208-J revised. Fire was opened on this vessel at 7,000 yards and the range was closed until at 4,000 yards the enemy obtained a straddle with what appeared to be 50 caliber. This range was maintained until enemy fire was silenced when the range was closed and the decks were swept with 20MM fire.

2. The enemy vessel was then boarded by two officers and two men. There was no sign of life and the ship had begun to settle in the water.

3. An inspection of what appeared to be the commanding officer's cabin was started first. Drawers which were unlocked contained nothing of value and by the time an attempt was made to tear open lockers and locked drawers the boarding officer was driven out by the water which was then up to his neck. The package of mail was found in this compartment.

4. The rising water suddenly brought to life the prisoner in the captain's cabin, four men on deck, and one in the fore peak. All of these except the prisoner were promptly shot.

5. One man, apparently the helmsman, badly wounded, was found in the pilot house and he also was shot. This compartment was on fire but an inspection was made which revealed nothing but a smoke mask and one green covered book and some papers.

18 April 1944.

Subject: Gun action on 18 April 1944.

6. The one ship's boat was cast loose and put in use. Just as the boarding party with the prisoner started to leave the wreck the boat capsized and all hands had to swim back to the TAMBOR.

7. This was the only boat found on the vessel and was left completely flooded 100 yards from the wreck.

DRUM: Just as TAMBOR was preparing to leave the scene, DRUM had no time to react and was sent to the wreck. DRUM conducted 20M practice on the wreck which kindled additional fires in the vicinity of the pilot house.

An attempt was made to transmit on the evening of 18 April. NPM was called intermittently between 0942(2) and 1438(2) with no result. The complete report was sent blind at 1432(2) on 4235 JGS.

10. No answer or receipt of the message sent on 20 April has been received.

Subject: Attaches on Soviet Shipping by United States Submarines in the Okhotsk Sea.

3. From the foregoing it is evident that Attack (a) was made by the TADBOR but that Attack (b) was not made by a United States submarine. It is suggested that Attack (b) may have been made by a Japanese petrol vessel.

Reference (a) contains request from Soviet commandant that American submarines operating in Okhotsk Sea "receive appropriate instructions." All submarines ordered to patrol the Arctic Island Chain or the Okhotsk Sea carry with them copies of the latest information issued by the office of the Naval Intelligence concerning the routing followed and identifying marks carried by Soviet shipping. They are thoroughly irrefuted on these matters and they all have stated orders not to attack Russian shipping. Interrogation of Commanding Officer and a study of patrol reports lead to the belief that the trouble lies not in submarine Commanding Officers receiving proper instruction but rather to a laxity on the part of Soviet shipping masters in carrying out their instructions. The most specific complaint is on the following:

(a) Failure to follow prescribed routing.

(b) Side markings too obscure to be detected at normal torpedo ranges.

(c) Illumination not burning during fog and low visibility.

(d) Illumination too dim. (Council despatch 061511 of August 1944, stated that commencing 15 August the all around colored lights on the mast would be visible for five miles.)

5. Recent patrol reports contain many incidents of the above nature. The following have been chosen at random:

Ser. 0017-05
Subject: ATTACKS ON SOVIET SHIPPING BY UNITED STATES SUBMARINES IN THE OKHOTSK SEA.

"1315
Identified as properly marked Russian "Liberty" ship, except that his identification flag list was for prior time period and flags were hoisted in reverse order. Let him go by at 1000 yards."

6. The following is quoted from District Intelligence Report, Seventeenth Naval District, Merchant Vessel Boarding Report of Soviet Vessels boarded at Akutan, Alaska, from 14 to 20 July, 1944:

"......the master of the OB, Stepan Panfilov, was anxious to reach Petropavlovsk as soon as possible, and thus took the direct route which would bring the approximately ninety one hundred and fifty miles. It is common practice among Russian masters to deviate from prescribed courses in their desire to save time."

Submarines patrolling the Okhotsk Sea have been seriously handicapped by the restrictions imposed regarding identifying their targets before attacking. They take on considerable risks by approaching their targets closely to identify them. It is known that these restrictions are necessary but it is felt that the Soviet ships, in their own interests, should cooperate in every way possible to simplify the identification problem. It is requested that representatives be made to the Soviet government to impress their shipmasters with the necessity of rapidly complying with existing instructions and the necessity of carrying their illumination and markings as brilliant and well defined as possible.
