15 March. Proceeding to Midway via Wako Island, she roconitored around various islands in the Pacific. On 15 April a lightflash illuminated a ship about 2 miles ahead of TAMBOR at 2240. It was after midnight that a spread of two torpedoes scored one hit. The ship was a fully loaded tanker and sank storm first thre minutes later with at least five heavy explosions.

Arriving back at Pearl Harbor for a refit period, TAMBOR was ordered to take station on a scouting line for what developed into the Battle of Midway. During this ongagement, the submarine inadvertently cruised for four hours in the middle of the Japanese invasion force and at one time had eight Japanese cruisers in sight. In view of the possibility that it was our own task force, no attack was made. After ascertaining that the force was Japanese TAMBOR took out after them as they rotated to the west. About 800 miles west of Midway, TAMBOR was severely bombed by our own B-17s. Considerable damage resulted which forced the sub back to Pearl Harbor.

Lieutenant Commander S. H. Armbruster relieved Commander Murphy as commanding officer and the submarine departed Pearl Harbor on 24 July after a thorough overhaul at Pearl Harbor. While close to Pearl Harbor, the submarine was attacked by a Japanese submarine torpedo from a distance of 8,000 yards and forced to dive.

While patrolling west of Woto Island on 7 August an armed passenger-frightener of 7,189 tons similar to NOJIMA MARU was seen rounding a point of land. One torpedo was fired at 0925 which sank the ship. TAMBOR went to deep submergence to avoid aircraft detection from the airfield which was within sight.

The sub was reconnoitering around Ponape on 21 August when a freighter was sighted standing out of Ponape. Three torpedoes were fired at the ship at 0709 for three hits. It was too many for the MARU and she went down to the bottom.

The first of September commenced with a morning contact on a tanker similar to TOA MARU. The range was long and TAMBOR approached within firing range and unloads four torpedoes. One hit was scored and the tanker was apparently sank. An escorting destroyer sighted the periscope while TAMBOR was watching the tanker. The submarine was for a while out of the way and the destroyer sighted the tanker and fired a torpedo at it. The submarine was fired at the tanker and the destroyer fired a torpedo at it. The submarine was fired at the tanker and the destroy

2207 missed and TAMBOR fired two more at 2237. One torpedo struck amidships and the ship went down by the stern until she disappeared.

A thirty-ton sampan was sighted around noon on 10 November and TAMBOR closed to investigate. Seeing that the sampan had no guns, she was ordered alongside and all her crew, nine men and a boy, were taken prisoner. The sampan was sunk by machine gun fire and 3" gunfire. TAMBOR returned to Freemantle on 19 November as the fourth war patrol ended.

The fifth war patrol commenced with TAMBOR's departure from Freemantle in early December as she headed for the Sundra Straits off Krakatoo. Christmas was appropriately spent off Christmas Island and New Year Day was strictly a Japanese celebration as far as the crew aboard the TAMBOR was concerned. A Jap destroyer was fired at by torpedoes and missed. The destroyer in turn gave the submarine a working over which added nothing to the holiday spirits. TAMBOR arrived back at Freemantle early in February after an unproductive patrol.

The sixth war patrol commenced with a special mission to the Philippines as TAMBOR departed Freemantle on 18 February 1943. In the early morning of 22 March a ship was sighted about five miles away and TAMBOR closed for an attack. The ship was a naval auxiliary of 3000 tons and attracted three torpedoes from the submarine. One of them hit the target and sank the ship. An aerial bomb confirmed the TAMBOR skippered that it was time to "take her down" and it was not until years later that he found out that this ship was definitely sunk.

On 29 March a freighter was sighted at 0720 with an escort vessel. TAMBOR worked her way into a firing position and lost no ship. The torpedoes were fired at a target at 1430

— page 6 —
TAMBOR was forced to submerge and take a depth charging for her efforts.

Smoke on the horizon in the early morning of 29 May extracted the attention of TAMBOR and started an approach which revealed a second ship. A flight of seven Jap planes came into view and the sub was forced to dive before the ships' courses could be determined. After staying submerged for a short while, TAMBOR came up for another look at the Jap ships and maneuvered to attack. Three torpedoes were fired at the first cargo vessel. Three explosions followed and two hits were observed. The second cargo vessel slowed as if to aid the stricken ship and three torpedoes were sent after her. They missed and the ship started throwing depth charges from a Y-gun and cleared the area.

The first ship had sunk and the crew had abandoned the ship in two lifeboats. TAMBOR approached the lifeboats to capture a ship's officer. Two of the Japs jumped over the side and came to swim away. The remaining men in the boats appeared to be Chinese and many waved or appeared to be not too regretful of their situation. When asked where the officers were they pointed to the two swimming in the water. The two swimmers were reluctant to be captured and a few bursts in the water from a tommy gun failed to coerce them. The men in the boat finally caught one of the swimmers and it was learned that he was the chief engineer aboard the ship which was manned by a Chinese crew, with Japanese officers.

In the darkness of early morning on 2 June a white light was sighted and TAMBOR approached to determine the course of the target. In a firing position by 0303 the submarine fired three torpedoes. The third one struck the target with a great explosion and the target broke in half and disappeared below the surface in a few minutes. TAMBOR cleared the area as torpedo tracks from an enemy submarine narrowly missed her.

Just after midnight on the night of 6-7 June, TAMBOR sighted a dark object on the horizon and closed for an approach. In a lift over two hours a good firing position was attained and three torpedoes were sent streaming through the dark water. One hit scored and was all that was needed for the target, a 6,000 ton freighter, far rapidly.

A week later two torpedoes were fired at a large tanker but the position was not too favorable and both torpedoes missed. The run was conducted around Makassar Straits and Tonkin Gulf. TAMBOR returned to Freemantle on 27 June after a 52 day patrol.

The eighth war patrol commenced with TAMBOR's departure from Freemantle on 20 July 1943. She conducted offensive patrols against enemy shipping in Makassar Straits, Tarakan and Belahan Straits. On the afternoon of 3 August a convoy of five freighter escorted by one destroyer was sighted. Two targets were selected from the group and the position attained on the first freighter was excellent. Two torpedoes of a spread of three ripped into the ship and exploded for a sinking. A fourth torpedo fired at another

— page 7 —
1943, 16 August at 4,000 ton freighter was sighted steaming 1,700 yards from the beach and TAMBOR was paralleling the course 6,000 yards from the beach and made battle surface with the target at 7,000 yards. The freighter immediately opened fire and turned slightly toward the beach. TAMBOR was about to force the freighter into the beach by gunfire but a missfire prevented surface firing and the sub dove for a submerged approach. When the sub surfaced again the freighter opened fire and a patrol boat was sighted approaching from Cammann Bay forcing TAMBOR to escape seaward. Several attacks on a Japanese convoy commenced on 21 August and led to convoy tracking for four days. The attacks were frustrated each time and TAMBOR finally ended the patrol by way of Midway and Pearl Harbor to San Francisco by 12 September for a Navy yard overhaul.

After completing overhaul and tests, TAMBOR churned her way through the channel into Pearl Harbor on 15 December 1943. She conducted training operations and on 5 January 1944, put to sea for h ninth war patrol which took her to the East China Sea. A NATORI class cruiser evaded attack when she countermarched during a rain squall.

On the morning of 28 January a large convoy was sighted and tracked until sunset, when another convoy on a reverse course was selected as a target. At midnight, two torpedoes were fired at the end ship, a 7000 ton freighter. The bow of the freighter swung around TAMBOR at flank speed but both torpedoes tore into the ship sides and she went down by the bow. An escort pointed its bow straight toward TAMBOR and all hands on the bridge were convinced that ramming amidships was inevitable. The after 20MM gun opened fire when the escort was on the starboard beam. The submarine con tinued to swing to the left and the escort passed astern at a distance of 20 yards. The 20MM fire was very accurate at this o'clock range and probably prevented the escort from opening fire. The escort pursued TAMBOR until she escaped and the submarine then reversed course to search for the convoy but contact was lost.

A convoy of two ships and an escort was sighted on 2 February in the Straits of Formosa. A submerged approach was made but an attack was thwarted when the ships turned away. After trailing all day, tracking was commenced at dusk. At moonst three torpedoes were fired at the lead ship, a freighter of 8600 tons. Targets were shifted and three torpedoes were sent racing after the second ship, a 9500-ton tanker. The escorting destroyer came charging in as two hits ripped into the freighter, followed immediately by a hit and a heavy explosion in the center of the tanker. TAMBOR swung away but was still unhurt by the burning tanker and dove when the destroyer closed the range to 2,000 yards.

A severe pounding with depth charges followed which drove TAMBOR into the bottom at 268 feet. Serious leaks flooded the

26 May as the sub hulled to gain a good track on them. One was a diesel freighter of 6,400 tons and the other was a patrol craft. Four torpedoes were fired at 2320 for two resounding hits. TAMBOF drew clear of the scene to avoid an attack from the escort. The freighter disappeared from the radar screen and the escort vessel, instead of attacking, ran the other way. TAMBOF returned to the scene of the sinking but found nothing but wreckage floating on the surface.

: An attack on a three-ship convoy was frustrated on 27 May by alert escort vessels and enemy aircraft protection; TAMBOF's first experience with this latter type of anti-submarine measure. The submarine returned to Midway by 2 June with two or more ships sunk to her credit with one more damaged. Two days later Lieutenant Commander Commander W. J. Germershausen, Jr., relieved Lieutenant Commander Kefauver as skipper of the submarine.

: The eleventh war patrol commenced with TAMBOF's departure from Midway on 16 July and took her off the northeast coast of Honshu, southern coast of Hokkaido and in the vicinity of the Kuriles Islands in the Okhotek Sea. On 28 July, TAMBOF made a rapid contact on a small freighter in the early morning darkness. Three torpedoes sped toward the Jap ship for two timed hits but the ship continued on its course and speed. Radar contact was finally lost on the target indicating a probable sinking.

: On 13 August, TAMBOF arrived at a rendezvous position to meet the submarine POMPON but could find no sign of her. A radar contact however, brought TAMBOF to within 2,000 yards of a Jap freighter of about 4,000 tons. Four torpedoes were fired for two hits and the periscope sight trained on the ship to take pictures while two lifeboats were lowered as the Japs abandoned the ship before she went down.

: During the early morning of 15 August, TAMBOF sighted an unescorted heavily-smoking tanker on a course for Paramusihiru. After tracking the tanker, TAMBOF completed an end around and submerged ahead of the ship for a daytime periscope attack. Four torpedoes were fired in a large spread but all missed. TAMBOF surfaced to track the target for an attack again at night but the tanker's gunfire forced the submarine to dive and the pursuit was abandoned as the ship cleared the area.

: TAMBOF returned to Midway and proceeded to Pearl Harbor where she arrived on 1 September for a refit period after spending 47 days on patrol which resulted in the sinking of one ship of 4,000 tons and damaging another. After refitting at Pearl Harbor

TAMBO proceeded to the Bonins on 3 October via Midway. The patrol was conducted south and east of Sagami Nada, Honshu with sweep north of the Bonin Islands.

A radar contact on the night of 15 October was tracked for course and speed. A large pip and two smaller ones indicate a ship with two escort vessels. Four torpedoes were fired for one good hit which resulted in rumbling noises from the direction of the target and the disappearance of the large pip from the radar screen. When contact was regained, only the two escorts remained.

TAMBO soon commenced patrolling in a new area in Empire waters along the immediate approaches to Tokyo. On the night of 18-19 October a radar contact put the submarine in position to fire four torpedoes at a destroyer escort of 1,000 tons. Two hits and two flashes were seen on the bridge and the ship went down.

Proceeding to Saipan for voyage repairs, TAMBO encountered an enemy trawler and damaged it in a surface gun action. After conducting voyage repairs at Saipan, TAMBO proceeded in a wolf pack sweep of the Bonin Group. A large Japanese patrol vessel was tracked on 15 November and six torpedoes were fired at her in two separate attacks. TAMBO wasted no more torpedoes on the ship and in the afternoon of the following day came to the surface to slug it out with gunfire. The first 20 millimeter gun was in action 17 seconds after the hatch was opened and the Jap ship returned the compliment with a small deck gun and machine gun fire. The target ship began to sink in about 30 minutes and finally went down completely.

Two wounded prisoners were taken from the water; the only Jap survivors. TAMBO had one casualty when the trainer on the 5-inch gun was seriously wounded in the left leg by an enemy shell. On 18 November, the wounded sailor along with two Japanese were transferred to the destroyer GRAYSON and TAMBO set course for Pearl Harbor, arriving by 30 November. On her twelfth and last war patrol TAMBO was credited with sinking three ships totalling 5,200 tons and damaging one ship of 200 tons.

After voyage repairs at Pearl Harbor, TAMBO turned eastward for San Francisco and arrived at the Mare Island Navy Yard for overhaul on 10 December. Lieutenant Commander M. Forrera relieved Commander Germenhausen as commanding officer on 2 February and on 15 March, TAMBO arrived at the coast guard Air Station, Port Angeles, Washington to commence training operations with Navy Patrol aircraft. In addition to this regular duty under Fleet Air Wing Six, TAMBO engaged in tests with the defenses of Seattle, and with the Canadian Navy and Army. On 17 September the gallant undersea raider reluctantly departed for decommissioning which finally took place at Portsmouth, New Hampshire on 10 December 1945. By Directive dated April 1947, the USS TAMBO (SS 198), was to be transferred to the NINTH Naval District to train Naval reserves.

1830, Nov. 19th, departed PAUL in company with TRITON, who had orders to patrol south of WAKE. Set course for WAKE. Speed 12. 0100, Nov. 22nd, submerged to investigate ship sighted to northwestward. Ship proved to be a tug with two barges in tow, apparently headed for WAKE. 1800, Nov. 25th, submerged in assumed area and began defensive submarine patrol. Nov. 25th to Dec. 6th. During this period WRIGHT arrived at WAKE, landed aircraft equipment and departed, and a squadron of intercept occurred. At 7-8. On Dec. 7th, I decided to move well to the eastward submarine in order to gain a longer run with the sea for making fresh water, as the sea was making up to such an extent that the rate of dis-tillation would be low while pounding into it. I had consulted the Chief of Staff prior to departure on this point and obtained his authority to do so. My last observation of WAKE was at 2000. By nightfall, when we surfaced, we were about 40 miles 375' true from the island, and we continued on course 660 while making slow speed during the initial stage of the battery charge. At 0630, Dec. 8th, came the first newfow hos-tilities, via radio broadcast. We immediately changed course to regain our patrol station. Meanwhile, numerous messages had been deciphered, which provided a navy, general picture of the situation. CINCAPe advised WAKE and the patrolline submarines that a renewed attack on WAKE by air and surface craft was probable during daylight of Dec. 8-9. This was the first indication I had that WAKE had been attacked on Dec. 7-8. 7-8. Dec. 8-9. Submerged at 1740, about 8 miles North of WAKE. We were not sure of our position as WAKE was blacked out. When WAKE became visible we closed to about 4 miles and patrolled east and west. At 0050, Dec. 9th, noted large fires on WAKE, one of

bird in the direction reported.
We surfaced at 6:22. I decided that I would not report the plane, as I was not sure that it had not been a bird.
The gasket held satisfactorily at 70 feet Cepth.

Dec. 19-20.
Very rough seas. Took water through the conning tower hatch and engine air induction valve so badly that I decided to slow from 11 to 6 knots for a while. The leaky gasket was permitting the forward main ballast tank to flood more freely than usual and making us dip more deeply into the swells. We started running the turbo-blowers normally, instead of every three hours. This with a slight reduction of the sea, made it possible for us to resume 11 knots after five hours.

Dec. 19-20.
Seas less heavy. We passed through latitude 15° N. longitude 175° W, at 0530, and changed course from 092° to 078°, heading for PEARL. As we were on the direct path between the HAMILTON and MARSHALL ISLANDS, I decided to commence Zigzagging at daybreak, just in case an enemy submarine running submerged during daylight were encountered.

Dec. 19-20.
Up to 13 knots again, although it is still rough steaming. At 2030 we submerged again, for a bird again. We had great difficulty diving, and it was fortunate that it was a bird. A large air bubble had collected in one side of number 4 fuel oil ballast tank which made us about 20 tons light. This was the first time any of us had encountered such an occurrence. I am inclined to attribute it to air bubbling out of the main ballast tank flood valves, when we run the turbo-blowers, and seeping through a leaky flood valve into the fuel ballast tank. We now went the fuel ballast tanks once each watch.

Dec. 20-21.
Zigzagging during daylight. Sighted a friendly patrol plane during the forenoon. Submerged to periscope depth and fired the emergency identification signal. Plane continued to hover, and as we were unable to see his acknowledgement of the signal, we fired the signal again. No visible response. "We fired it again. Then the plane turned away and we surfaced.
The leaky gasket held well at sightly feet.
I informed Commander Submarines that we would expect to rendezvous with a destroyer escort 93 miles 2500 from BAKERS FORT at 1630 GOT Dec. 23. I also asked him to no-

Enclosure: (A) USS TAMBO (SS198) Conf. Serial 051 dated December 24, 1941.

1. Forwarded, concurring in the comment contained in the basic letter.

2. In view of the serious nature of the casualty referred to in the Enclosure and from similar casualties suffered by other ships of this class, it is recommended that the troops platoon for the QJ JK-7 sound equipment be welded to the top structure of the ballast tank in all submarines of Submarine Squadron Six to prevent a recurrence of this casualty. It is considered that the increased safety factor gained thereby more than offsets the adventage of pulling sound heads for repairs in instances when the ship is not in drydock.

3. By copy of this endorsement the Commanding Officer of the USS TAMBO (SS198) is informed that his action in informing the Commander Submarines, Scouting Force, of conditions in the TAMBO has the full approval of the Squadron Commander.

(a) Air leaks in main ballast tanks from the high pressure air system will be corrected as ships become available by replacing high pressure air fittings with the now approved silver soldered type of fitting.

(b) Main vent operating mechanisms to remain reliable must be lubricated and operated frequently.

(c) Fuel oil ballast tanks should be periodically vented to prevent collection of air bubbles.

(d) Direction finder shaft jamming was probably due to misalignment, packing too tightly, or poor lubrication.

1. NAVAL TRAINING

PHASE I - PEARL TO HAVANA.

(a) Enroute
Departed PEARL 0915 (49%) March 15, proceeded MIDWAY via route north of island chain at 14 knots, training enroute, 0600 (-12) Ma.ch 19, entered MIDWAY lagoon. Topped off with 13,500 gallons fuel. Departed MIDWAY 1200 (+12) same date. Conducted submerged training in afternoon and set course 239° speed 14 knots for 4 hours at 1900 (+12).

At 0000 (-12) March 20, set clocks ahead 24 hours, skipping that date.

At 2015 (-11), March 23, received intelligence indicating that an enemy merchantman might depart 4,000 tons of KILOGRAMS at any time. Proceeded at full power to intercept the ship in case she were to depart before our arrival.

(b) Reconnaissance of 24.

Made lantern report on 25° true distance 7½ miles at 0745 (-11). Reconnoitered 24 at distances of 1 to 3 miles off shore, from 24, etc. Cloakwise during forerun of March 24.

Generally speaking, 24 appears quite unchanged from our last observation of it on December 14, 1941. The high water towers remain standing. The rangefinder 24 appears to be a sizable landplane unit to be undamaged. There appears to be a sizable landplane unit basing at 24. Saw aircraft several times during the reconnaissance but was unable to identify them other than as landplanes.

On rounding PEARL 25 observed one destroyer, apparently HINAKAMI class, beached and stripped, about 1 mile east of the boat channel. On the shore near PEARL 25 were many sand mounds apparently dispersed.

The continued presence of aircraft in the air and the very clear water restrained us to short, infrequent (half-hourly) observations with very little periscope. Saw at least one plane at each exposure, and twice we flooded negative to duck easily possible detection from overhead.

(c) Attack on TUNISIA 24.

At 1000 (-11) sighted a small freighter (TUNISIA class, 2933 tons), apparently moored bow and stern to buoys at the best entrance. At 1115 fired one torpedo at her. Just after we fired an enemy plane 1st had been circling over the ship turned down the torpedo track directly for the periscope. We

took deep submergence immediately an turned to the southward at high speed, without waiting to observe the explosion. An explosion was heard, but the torpedo would have exploded on the reef within a few seconds of passing the target if it had missed.

It is not known that the target was sunk or even hit, because just as we were about to return to periscope depth a patrol craft of some sort approached and kept us at evasion tactics until 1500, by which time we were too far from the island to see anything through the periscope.

PLEASE II - MAKE TO ENTER TUN.

(a) Narrative.
Surfaced at dusk, March 24, and proceeded on course 207°, speed 14 knots, toward ATLANTIC.

Submerged twice for short periods during daylight of March 25 to avoid detection by aircraft.

(b) Reconnaissance of ATLANTIC.
1005 (-11), March 26, made landfall on HUNKITTO I. On starboard bow. Commenced reconnaissance of ATLANTIC until at distance of 3 miles off shore.

There was no evidence whatever of any air activity at ATLANTIC. Not a single plane was sighted in two days of almost continuous periscope observation.

In fact there is little evidence of such activity of any kind on any of the islands as viewed from seaward. The scrub and palm trees effectively obscure all construction except what appears to be a watch tower barely projecting above the trees on ATLANTIC I. A 6000 ton freighter of SHILOH class, anchored in the lagoon about 1500 yards of ATLANTIC, was the only ship visible. Two high slanting booms indicated possible construction work in progress on a small barren unmoored island north of ATLANTIC. At night dined autumnal lights were visible observed, once on ATLANTIC and once on ATLANTIC.

After reconnoitring ATLANTIC, RANDY, and ATLANTIC islands we took station where we would be able to watch the SHILOH MANU, as she had steam up. It being impossible to guard both

gave 6 miles visibility. The ship was zigzagging radically at 16 kts. both before and after dark. It was the SHIKO I and we had seen an anchor in 2nd TAKUNA lagoon.

"At 2030 (-11), the target having zigzagged into a position favorable for attack, fired three torpedoes, all missed.

"We submerged quickly as the target turned to ran, and after ten minutes of deep submergence came to periscope depth and saw the enemy's smoke well clear, surfaced immediately and gave 'case again at full power.

At about midnight, after we had again pulled up on his starboard bow, about 4 miles distant, he still did not a rain squall and we saw no more of him the remainder of the night.

He retired on his estimated course at 17 knots then, and at daylight, March 31, sighted his again broad on our port quarter, distant about 15 miles. Shadowed him at full power until we had reduced his angle on the bow to twenty degrees and then made a normal approach. He was not zigzagging, and had slowed to about 15 knots. Shortly after we submerged, however, he changed course about fifteen degrees to his left and passed just outside our high seas for, edge range, despite all our efforts to close him.

At 1000 (-11), March 31, fired four low-speed torpedoes, and 10,000 gallons of fuel on the SHIKO I and, we gave it up as a bad job and set course 2lo, speed 10 knots, for TAKUNA.

Saw no planes on March 31. Decided we would have time to take the slightly longer route and approach TAKUNA along the SAITAN track rather than from the northeastward. At 2030 (-11), March 31, changed to course 2.1 to accomplish this.

(e) Reconnaissance of TAKUNA.

0530 (-10), April 3, commenced submerged reconnaissance of TAKUNA from SAITAN PASS eastward to OTTA PASS. Results wholly negative. No shipping sighted entering or leaving, or anchored in LIGHT BAY or LIGHT HARBOR. One petrol craft was seen near TORRAS I, and two motor sampans and one large flying boat were encountered in mid-formation. These hampered our reconnaissance and prevented its extension as far as planned before dark. At 1900 we were still 11 miles from OTTA PASS.

At 1535 (-10), April 6, sighted mast bearing 194° distant about 15 miles. Turned and shadowed at high speed until it was determined that contact was with a single ship zigzagging on base course about 010°, heading for TAKAI. We were then about 120 miles north of KAVIANG. Sea glassy calm with long swells. Visibility excellent. Made approach and fired two stern torpedoes at the ship as he crossed at sea from IRO. IRO to starboard. Both missed. A minute later fired one bow torpedo with large gyro engine at 170° to starboard and sighted the target. The target was sighted at 170° to starboard and sighted the target. The target was sight

Title: U.S.S. TAIBON - Report of Second War Patrol.

(a) Off at 2:00 a.m.
Flashs began which apparently disclosed us to coast watchers who lighted small bright fires on the beach, on both sides of the channel, as we passed. A few minutes later some of high speed propellers were detected on three well sighted seaward. Although we were never able to see any boats, one was tracked down our port side and then on a constant bearing with increasing intensity. Decisive at that point to clear out fast, and did so. After running eight miles we stopped to list in and hear propellers noises on our starboard bow. We were to the left and after another half-hour of high speed running, we stopped again and heard nothing.

After we cleared the narrow channel the lights on shore were put out and no new ones were lighted.

Proceeded south to C.R. 35°N, 125°W. Go.GoG during the night.

(b) Off C.R. 35°N, 125°W and H.T.A.

Established patrol on east-west line about 6 miles south of C.R. 35°N. Good the morning of April 1st. Sighted a periscope apparently in dead for K.B.U.T at 1540 (-10) that date. Had some contact with a ship at 2300 which we were unable to develop. Next day, April 19th, sighted a two-masted single-stack warship on southerly course about 5 miles west of the Cape, apparently a patrol vessel, as it was making very slow speed and reversed course to the northward when the range closed to about 4 miles. Continued the patrol without further event (except for one brief and doubtful sound contact to the western during the night of April 20th) until the evening of April 23rd.

Our original orders were to reconnoiter G.S.B.L.T. and Salton. A shortage of fuel, however, coupled with consistent reports of our own aircraft that the had been no ship in at either of these places, infantrymen the decision to stick out the patrol on the eastern approaches to K.B.U.T., except for a brief diversion to K.B.U.T., where troops had been reported landing, and from where we could transmit the radio report to air of us without disclosing our station at the Cape.

According to our best estimate, we were at 35°N, 125°W during the night of April 23rd and reconnoitred that harbor on April 24th. Found no shipping nor activity of any sort there, but just before sunset sighted two patrol craft, similar to the

one we saw near CAPT ST. GOLDEN, patrolling several miles to the southward. So next day we patrol east south toward BUCK
PASSAGE, but visibility was poor and no contacts were made.
Withdraw to the northwest after dark, April 24th, with a view to transmitting the long radio re. out while on a northeasterly course. The radio transmitter, however, had along with several other items of electrical equipment, succumbed to the humidity, and was not in commission until midnight the following night. Meanwhile we maintained patrol midway between CAPT ST. GOLDEN and BUCK. At 0000 (-10), April 27, steamed on course 045, speed 12, while transmitting the radio message, and then changed course to 310°, heading for CAPT ST. GOLDEN.
One patrol craft was sighted to the southward, distant 10 miles, at daybreak, April 27, we submerged, but her reserved course after a few minutes and passed out of sight without coming closer.
Resumed patrol off CAPT ST. GOLDEN in the late afternoon, April 27, and on surfacing at dark began proceeding slowly up the east coast of K. LAND, with a view to reaching CAPT ST. HAMILTON next day.

(c) Chase of KINGSTON LIGHT.
At 1145 (-10), April 28, detected a medium sized transport, KINGSTON LIGHT class, northbound, hugging the coast, range 10,000 yards, engine on the bow 60 starboard, speed 14 kts. Closed until it became certain that her as long as possible hauling speed to the eastward on increase the distance from land, and at 1344 surfaced and gave chase at full power. We were still within ten miles of land, and could probably be sighted, but trusted to slow enough communications to enable us to spend the remaining five hours of daylight on the surface.
From our navigation it appeared that the target were going to alter course to proceed along the north coast of KINGSTON LIGHT and would have no better way to east sight or her by periscope, as she seemed to have passed CAPT ST. HAMILTON by that time, but she was then still on course 020. Estimated therefore that she would continue a northerly course, between limits of 045 (to KINGSTON LIGHT) and 350 (to TAUCH).

mean track angle 130 port, offset 20 right and 20 left, mean torpedo run 600 yards, mean gyro angle 400 left.
(c) both missed.

5. Second attack on above target.
(a) The target, observing the torpedo walks of the first attack, veers to port. Observing this we sighted the course 30° left and immediately fired one bow torpedo, with gyro angle 110° right, track angle 130 port, torpedo run 900 yards, which also missed.

6. Third attack on above target.
(a) The target apparently changed its mind about turning to port, and (probably about the time the second attack was detected) turned sharply to starboard.
(b) He did not run away to starboard, but turned through more than 270° and headed directly for our periscope. We beat on full speed and he crossed our stern again at a range of 400 yards.
(c) This time we fired two bow torpedoes, started 40 apart, then torpedo ran 800 yards, but both times also missed, although again our set-up looked good. We dropped his speed 4 knots for this attack, because of his maneuverings.
(d) The target turned to port again and came for us, this time leading us enough to force us down, and crossing directly over us on nearly parallel course. Then he hauled off to port, giving us no further opportunity for attack.

7. First attack on 7000 ton tanker.
(a) sighted target at night bearing 090 distant about 2 miles, angle on the bow about 100 starboard. Sound picked him up about the same time. Visibility was only fair - about 2 miles - except during lightning flashes. Target was apparently on a zigzag leg, as he was 3000ft the normal course for this passage.
(b) kept bow to target, using slow speed, until angle on the bow increased to about 300°. Then swung bow to starboard and, 15 minutes after the ship was sighted, fired two torpedoes, straight bow shots, on estimated mean track angle of 600° starboard, using target speed of 9 knots, range 1500 yards, spreading the one target length by eye.
(c) both torpedoes missed.
(d) meanwhile, we submerged to avoid being sighted.

8. Second attack on above target.
(a) After tracking the target clear of us by sound, we surfaced and gave chase.
(b) Having pulled ahead of him, but lost him in a rain-squall. We stopped and sound picked him up on our port quarter. We directed, we were able then to see him. We stopped and turned our stern to him.
(c) The second attack developed almost exactly similarly to the first, except we had stern to him instead of bow, and he was on a different course. This time we let the ID dictate the set-up.
(d) fired one stern torpedo at track angle 60° starboard. Plan was again to fire two, but just as the first one was fired we observed the target zigzag sharply to his left. So ceased firing. The one torpedo missed.

9. Third attack on above target.
(a) After turning left and running parallel to the target, we had again gained station ahead of him, we let the target cross his track again sound picked him up (after we had lost him a minute or so before).
(b) again the attack developed much like the first. We had two torpedoes, and we lost the track angle increase to 90° starboard before I fired. Furthermore we fired his speed to 11 knots, and spotted the torpedoes 42 minutes. A few two stern torpedoes.
(c) This time the torpedo that was of best 20 runs hit the target in the machinery spaces at and sank her. The other torpedo must have missed astern.

0. BUDDY A/B MEASURES

1. At 1AM, with a ship moored off the roof, an inner air patrol by one or two planes was observed. Also there was at 1AM some kind of a patrol craft with fairly efficient listening craft. About one hour after our attack on 1 small freighter there, during which time we had been talking, 3 knots on course 100 at deep submergence, this patrol craft reported us and closed, using short bursts of high speed. The air-escorted a 3 knots for about an hour, running to keep him in a rough air. In the meantime, and he apparently was not well enough satisfied with any of his reports to give us the chance to do the other's. (Or he may have been relying on the planes to do the depth-charging.) But we were unable to elude him completely until after another hour or two. (Intelligent balancing and his air-speed running on our part. He would report very correctly to our bursts of speed but apparently his snap bearing were not as accurate as those he obtained from our steady running, or he was unable to evaluate them as well.

2. Twice during the patrol we were depth charged by aircraft. In one case no depth charges were dropped until we had risen to periscope depth. In the other case, when we had risen to periscope depth, depth charges were dropped at 120 feet, which may not have been deep enough to prevent his attack. This attack was well executed, as the two explosions were quite close and heavy although no serious damage resulted. In the other case depth charges were dropped as we were raising depth charges were dropped as we were at 200 yards distant when they exploded. In each case there were only two explosions.

3. While patrolling the northern entrance to SHALOM BAY, sighted one 1200 ton destroyer engaged in circling DUTY OF "ONLY" ships at speed about 5 knots, apparently on antisubmarine patrol. Detected this vessel initially by sound, and as her crew were turning over very slowly when at deep submergence until she had passed over us and out of hearing. Then rose to periscope depth and cleared her at range about 6000 yards, angle on the bow 100.

4. While passing east of JUN or YOUR ISLAND on a dark night, noted two small steady lights at the water-line of the island shortly after we surfaced. Considered them at first to be possibly lighted snappers, but they did not move in relation to the shore so decided they were small fires on the beach. This was shortly after 1900 local time.

During the next hour lightning flashes on our starboard hand commenced, some of them very long and brilliant. As we

— page 46 —

2. DATE: 2 MAY 1943

were only four miles from the NEIHLID coast on our port
hand, it appeared quite possible that we might be seen from
shore.

Leanwhile the lights on DUNS OF YORK ISLAND, to starboard,
were extinguished.

At about 2000, just after an especially long flash of
lightning, a small steady light appeared on our port beam,
apparently at the shore line. Then another appeared one point
forward of the beam, and within ten minutes still another at
about the same speed, forward of that one. Coincidentally
sound reported fast propeller noise point about the starboard
beam, and the in broad on the starboard bow. Two sources of
noise, neither with any appreciable change of bearing, neither
very loud, both intermittent. A few minutes later sound re-
ported very distinct and sustained propeller noises sharp on
the port bow which drew readily aft. On reaching 200 relative
the bearing ceased to draw aft and the intensity of the noise
increased.

Leimwhile the lights flashed persisted, and we had been real-
ly about 5 knots, churning battles. The ship was not identi-
fied as a submarine, by a picket boat. Therefore increased
speed to 15 knots and altered course to starboard. Shortly
afterwards all lights on shore were extinguished.

At 2050 we stopped to listen, and could hear weak but sus-
tained propeller noise bearing 55 relative. At 2055 changed
course 40 left and increased speed to 15 knots again. Stopped
again at 2130 and heard nothing.

Judged that the lights on shore probably had some significance
once as regards detection of shipping through the narrow channel
east of DUNS OF YORK ISLAND, as they were likely only while
we were in that channel. If they were merely relative
fires, it seems somewhat extraordinary that they would be started
so long after dark, that they were so widely separated and so
regularly spaced, and that they were allowed to burn only a few
minutes.

5. In the vicinity of CAPE ST. GEORGE on two occasions sighted
a two-masted, single-stack vessel (not necessarily but possibly
the same ship), very similar in surveillance silhouette to the
TOLITSU LADY freighter of 200 tons we attacked at DUNS ISLAND,
but painted war-color.

On the first sighting, at 1000 local time, she was reversing
from a southerly to a northerly course at a point 5 miles west
of CAPE ST. GEORGE, making very slow speed, having apparently
patrolled south from DUNS ISLAND. This was the day after our cargo

with the picket boat.

The next time was at daybreak after the night during which we had transitted our 416 group radio report. She was then about 30 miles southeast of Pearl Harbor, making intermittent clouds of heavy black smoke, and on a northeasterly course.

"Be attempted to approach her submerged but she withdrew out of sight to the Southeastward.

9. JAPAN BATTLES

1. Port Prowler. On the second day of the patrol, personnel in the after torpedo room reported extremely abnormal noises in way of the port prowler which indicated that it had struck a submerged object. The snarl was observed immediately. When it was started again and slowly worked up to speed it made one startling, from and shudder at about 90 r.p.m., and thereafter behaved quite normally. While in 1 U.S. two days later the Engineer Officer over the side and inspected all three blades of the prowler and reported a slight nick in one blade.

2. Auxiliary Generator Set. During the Toroncon of the third day of the patrol a valve valve stem in one unit of the auxiliary on line broke and clashed with unit controller. Repairs were effected in twelve hours, but our only agree head, piston, and liner were used in no coins.

3. Electric-Primary device. One of the cables connected with the 7 equipment which passes outside the pressure hull between the control room and the submarine tower was found to be flooded after a test during exercise 2.94 feet on March 15th. This cable had been dry after a similar test submerged once made on leaving Navy Yard, have Island two weeks earlier.

4. H.O. 1.1 Main Generator. On March 27, 1944, found herring material in crankcase of No. 1 Main Generator. Investigation disclosed that one crank bearing in the bearing, the size of a dollar. Needed that bearings.

5. Train Storage Battery. After several cell-tors cropped because of the reliability of the cell, a new compound and also because the two of the cars in the middle and over rows are poorly supported by bed, so and are bulging slightly. This required constant watching throughout the patrol, numerous cell tors having to be lifted and rescaled.

U.S.S. THOR - Report of Second War Patrol.

9. LIEUTENANT COMMAND

6. Air-conditioning plant. One air-conditioning unit had to be decontaminated early in the patrol because of leaks in the refrigerant piping. Our supply of refrigerant was insufficient to permit test and repair of this unit, and at the same time replenish small losses of the other unit and the ice machine. Consequently the patrol was progressively hot and humid. (It is not comfortable submerged in warm weather when both air conditioning units are running.) And there was a strong tendency for electrical grounds and short circuits to develop, and for finely adjusted contactors and mechanisms to become inoperative through corrosion. At one time we had both periscope hoist rotors and the radio transmitter out of commission and zero grounds in two main rotors, all of which casualties are attributable to inadequate air conditioning.

7. Target bearing to be sufficient. After 40 days of gratifying service, our radar operator, Lieutenant Transmitter circuits developed short circuits that we were unable to remedy and their use had to be abandoned.

8. Refrigerating plant. A leak in the ice cover cooling coil put the ice-box out of corrosion on lay 5 (-11). We had already used up all our replacement refrigerant in the air conditioning plant, the one usable unit of which also went out of commission due to gas leakage the same day.

10. RADIO PROCEDURE:

(Last consecutive serial sent and received)

(a) Radar
Radar saved our ships twice by detecting a plane close above before the bridge's teletype had sighted it.
In some instances radar picked up aircraft as far away as 20 miles. On one occasion, however, initial detection was at 4 miles, and on another at 7 miles. The control room, of course, was there should be such variation in performance, but we think that the planes that sneaked in close to us were probably flying very close the surface.
Our radar picked up high land occasionally, but not low land, nor surf or craft.

10. RADIO RECEPTION:
    - Think we can tell when an enemy directional radar sweeps across us, by the appearance of our screen. That may be imagination.

(b) Radio reception.
    - Control reception on the surface, except for infrequent enemy interference.
    - To reception on submer or deep in NEZIRITAI area.

(c) Last message sent: Twinkle 1950/51 lay to Consubrinc.

Last message received: Tenor 1950/51 lay to TALBOR & LITCHFIELD.

11. SOUND CONDITIONS AND SAFETY LAYERS:
(a) Listening.
    - Listening conditions were good to excellent through the patrol.
    - On dark nights the listener was usually our best lookout.
    - We lay to or steamed at 5 knots to facilitate listening when we had no place to go in a hurry.

(b) Density layers.
    - Near land we found it frequently possible to change depth from 60 feet to 140 feet, and vice versa, without adding or discharging ballast. We attributed this to fresh water layers near the surf.

12. RADIO SAFETY:
(a) Left one an end of the chart at 1400 A.T., March 19.
    - Had two cases of heat exhaustion on April 5. One victim was back to normal after two days. The other was useless for the remainder of the patrol. Our one good air conditioning went was inoperative that day.
    - After two weeks of all-day submergence, 11 bunks were wet and sitting. Clothes and cooler gear in the forward and after torpedo rooms were ineffectual, practically everyone had a heat r. si.
    - One of the cooks burned his thigh cuite badly by spilling a pan of hot grease on himself. But he keeps on the job.

15. RECORD ADDRESS

(a) Torpedo depth settings. As a result of our night attack on JETTISON ISLAND, I had regarded instructions just received to set torpedo depth at least 5 feet below the estimated draft of the target, and intend there after tried to set them at the estimated draft of the target. I consider that our failure to sink JETTISON ISLAND was due to my over-estimating her draft a few feet and then, by using a depth screw, managing to have the cone torpedo that would surely have stayed her pace too far beneath her and fail to explode. I recommend erasing any depth setting below 15 feet when the target is any but a large heavily-protected warship.

Subject:  U.S.S. TAMBO (SS196), Second War Patrol - Comment on.

1. The TAMBO's second war patrol covered a period of fifty-nine days of which fourteen days were spent in assigned patrol areas and the remainder of the patrol reconnoitering and enroute. This low percentage of time on patrol station was caused by the large amount of reconnaissance conducted enroute to and returning from patrol station.

2. The numerous electrical grounds which developed in circuits within the hull are attributed principally to the fact that the TAMBO was forced by the failure of one air conditioning unit to operate in low latitudes with insufficient air conditioning. This experience is considered to be an interesting commentary on the value of air conditioning in submarines operating in the tropics. The air conditioning equipment of the TAMBO was overhauled at Navy Yard, Mare Island, shortly before the start of the patrol, but excessive leaks in refrigeration piping developed in one set shortly after the start thereof. Subsequent events demonstrated the wisdom of the Commanding Officer in conserving his supply of refrigerant by not attempting to make repairs with the accompanying danger of loss during testing.

3. Bulging of laminated cell jars throughout the battery appears to be a general condition. The maximum deflection exists in the tops of the second outboard rows of cells, which are unsupported except for some ineffective wedges. On the other hand bulging to a somewhat lesser degree has taken place in the outer rows which are supported by strong backs at their tops. The bulging is not considered to constitute any especial danger to the cell jars but in the case of the TAMBO the cell tops were sealed without rubber tape in under the compound, thus when the bulging took place the compound (which was somewhat fluid at the elevated temperature existing) found its way into the element where it did constitute a definite danger to proper cell ventilation. This is being made the subject of separate correspondence.

Comment on:

4. Habitability of the boat was poor due to the high humidity and temperature resulting from the failure of one air conditioning unit. Health and endurance of personnel were excellent, when the above is considered, and the TAMOB is deserving of credit for completing a long patrol in equatorial waters under extremely trying living conditions.

5. Contacts made on this patrol were aggressively developed and reconnaissance well conducted. Eighteen torpedoes were fired and one sure and one possible hit made. This is too low a percentage of hits and every effort must be exerted to improve it. The Squadron Commander does not concur in the TAMOB's recommendation regarding depth setting of torpedoes. Specific instructions in this regard have been issued and must be followed. It is believed that the TAMOB inflicted the following damage on the enemy:

One 7000 ton tanker - Sunk
One 3000 ton freighter - Possibly sunk or damaged.

1. This patrol covered a total of thirty-nine days, on which twenty-seven days were spent on station, either in the patrol area or on stations ashore.

2. Reconnaissance was excellent, and contacts were a. gressively developed. However, the analysis of attacks made which follows indicates that no much reliance was placed on the "seamen's eye" and the attack was made with a fairly utilized, with the result that there was no excessive expenditure of torpedoes. With the supply of torpedoes available, such unproductive expenditures cannot be justified.

3. The exact causes of the misses on the various attacks cannot be determined due to the lack of data, but the following factors contribute to misses are noted:

**ATTACK NO. 1**

The attack on this attack was made by DR from a position determined by ten-ends of the island. There was a constant air patrol over the next the target. The periscope was only exposed enough to see the target at the next end stack of the target, therefore, the target was not accurately known. Any aircraft would have detected the torpedo and not the target, because the target was not detected. The target may have been hit, but it is not probable that the torpedo hit the beach with exploded.

**ATTACK NO. 2**

The attack was made at the time the target silhouetted against the moon. A relatively sharp track was used because of fear of being sighted. The target was fairly large, 1500 yards, and a spread of 40 or 50 yards on the track angle is enough to permit the target to pass between the torpedoes. The target may have been hit, but it is not probable that the torpedo hit the beach with exploded.

Encounters with Japanese Cas and DDs.
At 0215 in position 270 T, 89 miles from MUMBAY,
on course 185 T speed 16.5 knots, weather clear,
sea calm, sighted the loom of four large ships
on the horizon distributed across our bow.
Estimated range 3 miles. Estimated angle on the
bow 45° port.

Ignorant of the location and exact composition of
our own surface forces and forewarned that they
might cross the submarine area during the night,
we turned to starboard (at 0217) to shadow these
ships from the westward (it being just after
moonrise) and try to identify them by silhouettes.
While turning three other ships were sighted to
the southwestward with small angle on the bow.
We put these astern of us, steadying on course
030 T. We maintained speed 18 knots. They drew
slowly to 224 T. At 0225, having lost contact,
we changed course to the left to 270 T, and at
0234 again to the left to 180 T. Regained con-
tact at 0235, the ships bearing southwestward

Inconclusive with Japanese Cds and DDs. (Cont'd) and heading northward. Changed course to 2000 to parallel them. At 0231 they altered course to the left and we came left with them to 210 T., and seven minutes later to 270 T.; trying to get them in the monostream. At 0306 lost contact and came left to 250 T. Regained contact at 0311, with the shins in south edge of the monostream, to the eastward, on a northeasterly course. We paralleled them on course 310 T. then but lost contact shortly afterward. At 0319 began altering course to the southward to regain contact and at 0325 steadied on course 200 T. At 0342 regained contact with two ships, apparently maneuvering on southerly courses, bearing still to the eastward. Changed course to 235 T., trying to gain bearing to the southward before daybreak.

We were still uncertain as to whether or not the ships were enemy. We judged that those in sight were destroyers and that those first contacted were larger ships, probably heavy cruisers. We estimated that these latter were beyond the destroyers to the eastward now.

We had transmitted a radio report of the contact with "many unidentified ships", giving their position, and received a receipt from LIDWAY for it at 0306 but if anyone knew from that report that the ships could not be units of our own surface forces he did not give us information.

At 0412, with visibility range increasing as dawn approached, the enemy character of the ships was definitely established when the near one turned to head directly for us, challenging "XJ" by flashing light. We submerged immediately and rigged for depth charge attack. Estimated range at time of diving was 4000 yards.

Encounter with Japanese CAs and DDs. (Cont'd.)
At 04:37 having been unable to detect propeller noises by sound, made a periscope exposure and sighted two 1000 cu. ft. cruisers. The near one bore 109 T., distant 900 yards and the far one 105 T., distant 13,000 yards. The far cruiser was on course about 265 T., the near one on about 235 T. Each ship was doing a great deal of signalling with a brilliant all-directional blinker light at the foremost-head.

This letter fact indicated (a) that the contact at 0342 was not with destroyers but with two of the "large ships" sighted at 0215, (b) that their larger silhouettes had caused us to underestimate their distance when "challenged," (c) that we had not been challenged at all, nor sighted, but that (d) instead the two ships had begun using the all-directional light for maneuvering that had been manifesting at considerable distance to the eastward of us while we were awaiting depth charge attack.

Even so, we were in fair initial position for an attack on the far cruiser provided he held his course, as we were less than 6000 yards from his track. He apparently followed the other cruiser on a jog to the south-westward, however, for at 04:52, after we had been running at full speed for twenty minutes on course 200 T., the distance to his track had opened to 3000 yards and his angle on the bow increased to 60 starboard. Both cruisers then were on course about 270 T. During the next twenty minutes more signalling and maneuvering ensued and at 0500, just after a periscope observation, we heard the sound of a distant explosion. With renewed hope we again made a long run at full speed but at 0516 there was no improvement in the situation.

It was noted before the explosion that the trailing cruiser had about forty feet of her bow missing. Her speed by plot was 17 knots.

Reported to CV 7 that we had been kept down and asked if the planes bothering us could have been friendly. Three hours later he replied that they could not be identified.
Estimated that the planes were probably Jap cruiser planes engaged in moonlight search for ships in pursuit, that we were not more than 100 miles from some Jap unit, and that we had been detected and reported.

Note: This is the only report of the Fortress attack transmitted by HONOLULU. It gave no information as to course, speed, location, and composition of the force attacked, which was quite disappointing. Also disappointing was the abrupt reduction of Catalina search. It appeared that henceforth we would have no assistance in finding orplies or any targets.
7 June, 1942. 1227/7 0025 TUMOR, TROUT and CRAYLING ordered by CTY 7 to continue pursuit. Other units stationed on circle radius 25 miles from MIDWAY.

1920 0720 Radar contact, range 7 miles decreasing. Made quick dive to 140 feet. Plane not sighted.

1922 0722 When at 135 feet we were severely shaken by two depth bombs exploding close aboard. Inspection revealed following damage: Much glass shattered throughout the ship, cork on forward conning tower bulked loose, housing of starboard air compressor cracked, casings of all four battery blower motors cracked, 1/4 battery blower vibrates badly, section of ventilation duct containing moisture trap in forward battery well cracked, upper window and prism of 1/4 parabolas broken and low-power of 1/2 periscope rendered unusable.

0423/ 1623 Changed course to 110 T.

Estimate: There were probably some 7ap ships within 100 miles of us when we sighted the cruiser plane this morning. They were probably bearing about 290, judging from the course of the scout plane. If so they are apparently making good at least 15 knots to the westward and are now well out of our reach. It is barely possible, however, that the plane was on a return leg to a unit on the reverse bearing which we passed to the southward during the night.

7 June, 1942. (Cont'd)

Also there may be a crippled ship still afloat, or a rescue ship, in the vicinity of the green flares sighted last night. Decided to proceed on course 110° during the four hours remaining until dark, and then to proceed to investigate in daylight the area of the green flares the following morning.

0430/8 1630 Commenced zig-zagging to widen our search band.

July 24
0915 (WX) Underway from Pearl Harbor in accordance with Commander Submarine, Fadrifle Fleet Operation Order No. 66-42 of July 21, 1942, under escort of LITTLEFLEED until dark. 12C2 (WX) LITTLEFLEED reported scouting periscope and depth charged some while TLEED cleared vicinity at high speed on zigzagging courses. LITTLEFLEED later reported it believed contact false. Proceeded to conduct deep dive (300 feet) for water-tightness, depth charge introduction for new men (300 lbs. at 250 yards) and bottle surface.

July 25-30
Arrange to stations. Have two short training dives.

July 31
1409 (WX) Radar contact of airplane, distance 13 miles, and made quick dive. Decided to remain submerged the rest of daylight period to avoid detection.

August 1
0535 (WX) Submerged six miles east of TAC. ISLAND, LITTLEFLEED and closed island to recommit. 0634 (WX) Sighted smoke or a ship behind toward ISLAND. CHINY, but not in position to intercept it. 0640 (WX) Sighted smoke from a vessel at pier on TAC ISLAND. 0900 (WX) Sighted two-engine bomber similar to K-1. SUB. 95 taking off from TAC ISLAND. This plane was sighted throughout the morning making a close inshore patrol.

August 2
0437 (WX) Submerged and closed ENIJUN CHINY. 0510 (WX) Decoded despatch ordering us to proceed to CHINY and investigate grounded K-1 on eastern tip. 0700 (WX) Sighted "Catcher" Type Patrol Boat and commenced maneuvering to get clear area to proceed on assigned mission, but in spite of maneuvers, the vessel presented an angle on the bow from 00 to 15° until 1030 (WX) when it headed back toward ENIJUN CHINY. 1108 (WX) Sighted small freighter, distance 10,000 yards, heading for ENIJUN CHINY. . . .s angle on the bow was nearly 90°, unable to close in to firing range. 1117 (WX) Sighted plane.

August 4
0440 (WX) Submerged and reconnoitered closely CHINY. ISLAND and strike eastern side of CHINY. TROLL. No evidence of grounded K-1 or any special activity in harbor.

August 6
0442 (WX) Submerged and reconnoitered CHINY ISLAND. NOVICE TROLL, no shipping present, so proceeded to NOVICE ISLAND.

August 7
0437 (WX) Submerged and reconnoitered NOVICE ISLAND and noticed steel framework near air field which appeared to be construction of new hangar. This was the only difference.

— page 88 —
0450 (K) Submerged and conducted high periscope search, but did not sight destroyers seen earlier.

August 28 0705 (K) Heerd explosions at 5 minute intervals which grew louder with each explosion, until approximately 0800 (K) when the explosions grew fainter. 0846 (K) Heard last explosion.

August 29 0720 (K) Sighted "Catcher" Type Patrol Boat. 0745 (K) Sighted another "Catcher" Type Patrol Boat. 0758 (K) Sighted the third "Catcher" Type Patrol Boat. 0910 (K) Sighted a flying boat. 0950 (K) Sighted small seaplane. 2057 (K) Heard "pinching" for a short time. 2200 (K) Sighted a patrol boat. 2338 (K) Sighted a destroyer, range, 6000 yards. Evaded on surface.

August 31 0342 (K) Sighted "Catcher" Type Patrol Boat. 1000 (K) Sighted "Catcher" Type Patrol Boat. Decided that, with bright moonlight and enemy patrols, we could not maintain a position at night close to the passes, so took station approximately 50 miles away in direction of RABUL.

Sept. 1 0949 (K) Sighted ship, distance 18000 yards. 0958 (K) Sighted destroyer screen and identified ship as tanker similar to TOA 1KUD. 1022 (K) Heard destroyer "pinging" 1031 (K) Fired four torpedoes at tanker, scouted one hit, target believed sunk. (See Part VII - Attack No. 3) 1041 (K) Destroyer dropped five depth charges, two thousand yards away. 1044 (K) It is believed that, while watching tanker, destroyer sighted our periscope, because it headed directly toward us. Went to deep submergence. 1049 (K) Destroyer dropped six depth charges which exploded fairly close on port side. 1220 (K) Heard heavy explosion in direction of tanker similar to the one heard when ship sunk at FOU.FE, which was followed by lighter explosions. Cleared area as expected heavy air and surface patrol there. 2110 (K) Heard "pinching". 2345 (K) Sound heard propellers.

Sept. 2 0000 (K) Sighted destroyer, range, 6000 yards. Evaded on surface.

Sept. 4 Left area and proceeded to D.II.LOLO Passage. 1241 (K) Sighted plane, distance, 12 miles. Submerged for one and a half hours.

Sept. 6 1140 (I) Sighted smoke on port beam drawing aft. Went ahead at full speed to cut ahead of target. Weather squally and from time to time lost sight of smoke. 1555 (I) Sighted target, a freighter 5000-6000 tons, as it came out of rain squall and apparently it did not sight us. 1721 (I) Submerged ahead of target.

— page 89 —
1805 (I) Fired two torpedoes which missed. (See Part VII attack No. 4) 1812 (I) Heard heavy explosion similar to torpedo explosion. Still heard target's propellers, but lost target in rain equally. Decided further chase during the night toward L.L.U. would be futile since target knew our presence and throughout daylight chase gave indications of high speed. Surfaces and set course for D.J.LLO F.S.S.7.

Sept. 9 0517 (I) Went through D.J.LLO F.S.S.7B and proceeded to NANT. P.S.S. 1352 (H) Ship's mate heard the heavy mass dead ahead. 1355 (H) Submerged and closed. 1500 (H) Identified mast to be small native sail boat and decided it was not worth while to surface and destroy. The heavy mass appearance was due to a mirage on the horizon. 1750 (H) Surfaced clear of sail boat. 2217 (H) Went through N.I.P. F.S.S.

Sept. 10 2200 (H) Received orders to pass north of TILL. and investigate destroyer and transport moving troops from DILL. 2230 (H) Entered "N.T.A. P.S.S.A.C. and steamed along north coast of TILL.

Sept. 11 0451 (H) Submerged ten miles east of DILL. 0900 (H) Had a close and complete view of DILL. H.A.BOR. Neither destroyer or transport there so proceeded west submerged.

Sept. 12 Submerged during daylight hours.

Sept.13-18 Proceeding to P.A.M.I.T.L.

Sept. 19 0400 (H) Arrived at rendezvous off P.A.M.I.T.L.

SECRET

PART IX - MAJOR DEFECTS EXPERIENCED (Cont.)

Radar The packing gland at top of vertical antenna leaked on deep submergence, grounding radar antenna. Moisture dried out somewhat on surface cruising, but operation was not as efficient as before.

Transmitter The relay coil for K-2 opened due to moisture on TBI-3 transmitter. The transmitter was dried out for copper-imately six hours prior to sending our first message, and moisture was still present as evidenced by the opening of the relay coil during transmission. The casuistry was undoubtedly caused by the failure of the air conditioning plant.

PART X - RADIO

Radio reception was complete.

Last message sent - TALKER 121140 of September 51. Last message received - CONTRACTOR 51 171045 of September.

PART XI - SOUND CONDITION AND DENSITY LAYER

Sound conditions were from good to excellent throughout the patrol with the exception of fish noises. It times those were so bad that all other sounds were drowned out. The fish noises were most prevalent in TALKER area, Temperature gradients never varied over two degrees from surface to 300 feet.

Every time a deep dive was made during this patrol, a heavy density layer was encountered. This layer varied from 175 to 225 feet and was quite noticeable as high speeds or radical changes in trim were necessary to penetrate it.

Subject: Ver Diary Third War Patrol report.

1. The following comments are considered pertinent and worthy of special mention.

(A) HEALTH AND MOBILITY
The defects encountered during this patrol particularly those affecting periscopes, pumps and air conditioning plant are being corrected by the repair facilities of the tender. Two main engines and the 300 K. V. auxiliary engines are being given complete overhaul, all connecting rod bearings were renewed in two main engines due to broken shaft, the total engine hours being about 4,000.

(B) HEALTH AND MOBILITY
Health and morale appeared to be excellent. The successful patrol was reflected in the morale of both officers and crew.

(C) OPERATIONS
The Division Commander commands the Commanding Officer, officers, and crew on their splendid performance of duty during this war patrol and is pleased to extend to them a truly merited "Hell Beno!" It is considered that the TAMBOUR should be credited with the following damage to the enemy:

SUN - One Tanker - 10,000 tons
One Merchantman - 7,000 tons
One Merchantman - 5,000 tons
TOTAL - 22,000 tons

SECOND ENCRYPTION to
TAMOR War Diary Ser.
03 of 9/19/42.

From: The Commander Submarine Squadron SIX.
To: The Commander in Chief, U.S. FLEET.
Via: (1) The Commander Submarines, SOUTHWEST PACIFIC.
(2) The Commander U.S. Naval Forces, WESTERN AUSTRALIA.

Subject: U.S.S. TAMOR - War Diary Third War Patrol Report.

1. This patrol, which covered a period of fifty-seven days, was made incident to the transfer of the TAMOR to Submarines SOUTHWEST PACIFIC. It was the first patrol conducted by the present commanding officer.

2. Material performance during the patrol is considered to have been satisfactory except for derangements specifically mentioned by the commanding officer. From the view point of effecting repairs the several defects stipulated are of a minor nature but their existence while the submarines was on patrol might well have seriously affected the military performance of the ship.

There has been a continuing history of flooding and grounding out of the TOR circuits in submarines of this Squadron which has tended to create the value of a fire control circuit which the Submarines Commander consider to be of prime military importance. This will be made the subject of separate correspondence.

The Tabor has had repeated difficulties with maintaining tightness of the piping of her air conditioning installation; every effort will be attempted during the current rift to place the unit in a satisfactory condition in this respect.

3. The health and physical endurance of officers and crew were excellent on this patrol, particularly so, in view of the failure of the air conditioning system, constructed on above, and the adverse effect this had on the habitability of the ship. The importance of the air conditioning installation has been commented on numerous times in previous reports, and its value can not be too highly emphasized.

The Squadron Commander considers that this was an excellent patrol, conducted in waters effectively patrolled by enemy air and surface craft. Of four catches made, three were successful; the TAMBO was depth charged after the third attack and on three other occasions. She was well handled throughout, and the Squadron Commander comments the new commanding officer, officers and crew of the TABOR for their performance on this patrol, and extends to 'all hands' a "Well done".

5. Commander Submarine Squadron Six credits the TAMBO with the following damage to the enemy:

Fairly accurate positions were obtained and the field was
laid within a mile of the desired position. From obser-
vation of mines leaving, the forward tubes voicing in dir-
ferent directions there will be natural dispersion of mines.
0144: Just prior to laying twenty-ninth mine, heard terrific
explosion which jarred the boat as much as a depth charge
at two hundred yards. Estimated seven mines were armed
by this time. Probably a premature explosion as could
not make out any wreckage in Flint geyser approximately
6000 yards astern. Continued mine plant.

    angle on the bow. At that time we were on course 090°,
    speed 4 knots. Swing hard right and increased speed to
    pull clear and then maneuvered to attain firing position
    on port side. Decided to stay on surface due to poor visi-
    bility, approximately 3500 yards, and close to firing range
    as soon as possible, as passing so close we may have been
    sighted.

2207 Fired three torpedoes. All missed. Swing right and passed

1218 Sighted 30 ton sampan, distance 9 miles. Decided to investigate it.
1327 Closed sampan and saw six had no guns so ordered her alongside. Got all her crew, nine men and a boy, on board. All turned out to be Japanese. As they did not have a small boat to put them adrift, took them on aboard. The sampan, in the meanwhile, had broken loose and drifted clear. As her glass floats were nearby, made no attempt to close her again as did not want fishing gear around propellers. Sunk her with machine gun fire and three rounds of three-inch.

1348 Proceeded on base course.
1352 Sighted most of ship 0400 on opposite course. Started maneuvering to attack position ahead of her.
1530 Attained desired position and submerged. During approach found out target looked suspiciously like "C" Boat of 3000 tons. As all data and position were so perfect, decided to use last torpedo on her. As the torpedo track passed ship, it was sighted. The ship turned toward us, tooted whistle, and broke out after flag on forward starboard yardarm. Started evasive tactics at periscope depth.

1648 Sound picked up high speed propellers on port quarter. At that time ship was on starboard quarter. Quick periscope observation sighted ship with 0° angle on the bow, distance approximately 6000 yards. From all appearances it looked like a destroyer. If the other ship within 1500 yards and with no torpedoes decided nothing could be gained by staying at periscope depth so went to deep sub-maritime and rigged for silent running. Surrised that there was no echo ranging nor depth charges dropped. From course of the ship, it seemed to be heading for CUCW WEST PASS and it may be the Japs are using this instead of the normal steamers line along west coast of PANAY.

1-10,000 ton freighter - November 3 - Tonkin Gulf
1-30 ton fishing vessel - November 10 - Sulu Sea

ACTION SUMMARY:
November 2:
Sighted Lanka Point Light and commenced laying mines as directed in operation order. One exploded prematurely.

November 3:
Sighted freighter, distance 3,000 yards, and approached on surface to firing position on port side. Fire-3 torpedoes, all of which missed. Since freighter showed no signs of cognizance of attack, stayed on surface, maneuvering to position on starboard bow. Fire two torpedoes, obtaining one hit amidships. Freighter sank by stern in less than 3 minutes.

November 10:
Sighted 30 ton sampan, distance 9 miles. Approached and ordered sampan alongside, when she was observed to carry no guns. Since she carried no small boat, took aboard her crew of 9 men and a boy, all Japanese, and sank her with machine gun fire and three rounds of three-inch.

SPECIAL INFORMATION:
Enemy Beacons:
On night of October 25, 1942, Tangong Trang Light on Borneo coast was lighted with normal characteristics.
On night of November 1-2, 1942, Lanka Point, on northeast coast of Hainan, was lighted with normal characteristics.

FIRST ADMISSION DATE to
C.O.TADM 4th Air
Patrol report AL6-3
Ser. 74 of 11/21/42.

From: The Commander Submarine Squadron SIX.
To: The Commander Task Force FIFT-002.

Subject: U.S.S. TADM, Fourth Air Patrol - Comment on.

1. Forwarded. This patrol was of short duration lasting 39 days of which 25 were spent north of the Navy Barrier. This was a combination mining and torpedo patrol and was terminated by expenditure of torpedoes.

2. Material performance during patrol was highly satisfactory excepting for one unit of air conditioning plant being inoperative as a result of a leakage of gas. The number one periscope is being replaced by a tender spare and will be reconditioned and available for re-issue.

3. Habitability was considerably impaired by the loss of re-frigorating gas from one air-conditioning unit; in spite of this, health and personnel endurance were excellent.

4. The mining mission was successfully carried out; one mine exploded prematurely. Ten enemy surface ships and no enemy aircraft were sighted on this patrol. Four torpedo attacks were made; one was successful, resulting in the sinking of a 10,000 ton freighter. This ship was attacked twice; three misses were made on the first attack; the ship apparently did not know she had been attacked and the TADM was able to get into position for the second attack and sink her. Although this was a high expenditure of torpedoes on one target, the TADM is to be encouraged for staying with this target until it was sunk. A 30 ton fishing sampan was sunk by gun fire after its crew of ten ran had been taken on board the TADM. The Commanding Officer states that the three torpedoes fired on the two unsuccessful attacks all passed under the the targets and failed to explode. The large number of apparent exploder failures is a matter of grave concern; this problem is being studied continuous-ly and every effort is being made to solve it.

5. The TADM is credited by the Squadron Commander with the following:
   1 - 10,000 ton freighter - Sunk.
   1 - 30 ton fishing vessel - Sunk.

Front: The Commander TASFICE FIFTY CII.
To: The Commander in Chief, U.S. FLEET.

Subject: U.S.S. TAIWAN - Fourth War Patrol - Comment on.

1. Forwarded, concurring in the first endorsement.

2. The decision of the Commanding Officer not to attack the 2000 ton patrol vessel on October 31 because of its proximity to the intended mining area is concurred in.

3. The night surface attacks on November 3 bring out the point that a straight shot is much preferable to a curve fire slot and much more likely to result in a hit.

4. The 10 survivors of the 3C ton sampan sunk November 1C, were turned over to the Australian Military Forces. Details of information obtained is being forwarded separately.

9. Major Defects experienced.

The following damage caused by the attack:
The two unknown insulators on the foremast were broken and wore removed. Scifety tank vent gasket was blown off its seat and was found hanging on the vent linkage. The old gasket was put back in place. The linkage on the boilers in both the control room and conning tower manometers was sprung causing false readings. The forward pressure proof regulator on the bridge was put out of commission. The target bearing receiver in the conning tower had an error of 15 degrees introduced because of loose connections. Then the connections were tightened, the error disappeared. The conning tower and control deck were thrown out of operation about three weeks. A for light bulbs were broken, and a for each starting lights started looking slightly. One oil leak was damaged beyond ships force repair, and the second hand on another was jarred off its slide.

The 3F radar came inoperative after the first gunfiring and remained so throughout the patrol. Numerous failures were recorded and corrected, but the radar remained inoperative. It is believed that further failures like the antenna system, possibly as a result of depth charging. A detailed report of failures found has been forwarded to the Squadron Maintenance Officer.

During the patrol, about twenty leaks developed in joints and valves in air conditioning piping. Halfway through the patrol the number one unit was secured to conserve from. The 3F started her patrol with 5 bottles of from and had less than one bottle remaining on her return to port.

C.O. TALBOR
A12 Serial C-521 of January 28, 1943.

From: The Commander Submarine Squadron SIX.
To: The Commander Task Force FIFTY-ONE.

Subject: U.S.S. TALBOR - Fifth War Patrol - Comment on.

1. The TALBOR's fifth war patrol covered a period of forty-two days of which twenty-six were spent in reconnoitering sixteen enroute. Part of a day was spent in reconnoitering Christmas Island both enroute to and returning from the patrol area in Sunda Strait.

2. The TALBOR will be refitted by FELIAS in preparation for the next patrol. TALBOR arrived in port in excellent state of cleanliness, and the thoroughness and industry on the part of the crew in the maintenance of material while on patrol is evident. Preliminary work in preparation for current refit had been painstaking, and will be of great assistance to tender and refit crews in expediting the necessary repair work which is minor in nature in spite of the severe depth charging received by TALBOR on this patrol. The importance of air conditioning in submarines operating in the tropics is well demonstrated by the deleterious effect the failure of this equipment had on the personnel of the TALBOR. Every effort will be extended by the tender repair force to remedy the defects in the air conditioning installation for TALBOR during the current refit. The special report on the 5d radar mentioned by the commanding officer has been received and corrective action is considered to be within the capacity of the tender repair force to accomplish although the Squadron Commander considers that the ability of the 5d radar to withstand depth charge shock is questionable due to a lack of ruggedness.

3. Health, habitability, and personnel endurance were below average on this patrol due to casualties to the air conditioning equipment; past experience has definitely proved that good air conditioning is necessary for submarine operations in the tropics.

From: The Commander Task Force Fifty One.
To: The Commander in Chief, U.S. FLEET.
Via: The Commander Southwest Pacific Force.

Subject: U.S.S. TAIWAN - Fifth War Patrol - Comment on.

1. Forwarded concurring in the remarks contained in the first endorsement.

2. The results of this patrol were disappointing not only because of the lack of tangible results but also because the area was not thoroughly exploited. Practically the entire time on station was spent in the extreme southern portion of the assigned area during daylight and to the southward and westward of KAKATAU ISLAND during darkness. This covered only one of the several possible approaches to SUDA STRAIT. It is possible that the enemy after learning of a submarine's presence of KAKATAU ISLAND on January 1, may have routed shipping through the northern part of the TA 30th assigned area via the shallow water routes north of SEDDI and SEDDUT ISLADS or to close along the west Java coast. It is a well known fact that the enemy takes full advantage of the protection from submarine attacks which is afforded by shallow water routes. Coverage of the area in the vicinity of KAKATAU ISLAND might have been productive of more contacts.

3. FILING FISH: COVOK on CHIUTAS ISLAND was reconnoitered on two occasions but no periscope pictures were obtained of this area. Pictures of enemy occupied territory may prove of great value for future operations and should always be obtained when feasible.

With respect to the attack on January 1, and in amplification of the remarks contained in paragraph 4 of the first endorsement, it is noted that the course of the target, but not the speed, was accurately known and that torpedoes were angled from 390 to 930 left, giving track angles between 90° and 146° port. All torpedoes were fired at points of aim within the limits of the target with no offsets applied. It appears that on first contact the TA 30th was in an ideal position from which an excellent firing position for small gyro angle shots on any desired track angle could have been reached. The use of sharper track angles to allow for greater errors of the speed estimate, small gyro angles on torpedoes and a spread designed to compensate for control errors would have greatly increased the chances for success.

11. MAJOR DEFECTS OBSERVED:

(a) Excessive cunty of Iron gas was used because of leaks which developed in the air conditioning systems.

(b) The following changes were caused by close depth charge explosions:
   (1) Cracked or broken parts of 2 air compressors about 6 inches apart about 6 inches.
   (2) Rook 6 sound projectors' mails of tracer transmitted in straight lines. It enters the transmitting or casing.

(c) Three cylinders of liners failed. Two of these liners were in 2 main cells and the other was in 2 main cells. It is not clear that one of the liners was cracked but it left on patrol because there was a small fresh water leak in it and engines. It is not clear that liners were removed, the engine room was not ready or the crack of one of the other liners replaced, it seems likely that its failure was due to a material failure.

12. NOTES:
Radio:
No difficulty encountered in radio reception.
Radio operator satisfactorily through-out the patrol. Found that a (front deck) dogtrot on stern, exposed conchators as almost a statement to the navigator's attention of the receiver was necessary to make boat results. Radiotele varied with the weather conditions and on one occasion, on a clear night, had a "flyby" of land beyond the range scale, even at 15,500 yards. It proved to be a great hit in navigating in calm seas during reduced visibility.
Sound:
Sound conditions were fair to good. The firing waters in the Philippines, other Pacific waters were unobstructed.
Air:
Conditioning: At least 10 and that which was the time we met a taste of hell. The "air" was fairly good, but the conditions were not as bad as they were in the Philippines. The air was not as bad as it was in the Philippines, but it was still not good. The air was not as bad as it was in the Philippines, but it

Serial No. 0128
U.S.S. TAUYOG, Flagship,
April 15, 1943.

FIRST ADDRESSMENT to
CO, TAUYOG SS1987A12
Serial C-6 of 4-14-43.

From: The Commander Submarine Squadron SIX.
To: The Commander-In-Chief, U.S. Fleet.
Via: (1) The Commander Task Force SEVENTY-ONE.
    (2) The Commander SEVENTH FLEET.

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

1. The TAUYOG's sixth war patrol covered a period of fifty-six days of which forty-three were spent north of the Malay Barrier.

2. The TAUYOG is currently being refitted for the next patrol by the PELIAS and should be in all respects ready within the normal refit period.

3. Health and personnel endurance were excellent on this patrol and officers and men returned in good physical condition. This may, at least in part, be attributed to proper functioning of the air conditioning equipment during the entire patrol.

4. Only five contacts were made with torpedo targets, two of these being with the same target going into and leaving DAVAO. Two of these contacts developed into attacks using three torpedoes on each and obtaining one hit on each. There was no confirmation of sinking the ship on either attack. 33.3 percent hits were made with one erratic run. The assigned areas were well patrolled.

5. The Commander Submarine Squadron SIX congratulates the Commanding Officer, officers and crew on a successful patrol. The TAUYOG is credited with inflicting the following damage on the enemy:

| DAMAGE | TOTALS |
|||
| 1 Navel Auxiliary (unidentified) | 2,500 tons |
| 1 AK (unidentified) | 5,000 tons |
| TOTAL | 7,500 tons |

SECOND ENDORSEMENT to
C.O. TAHOT 1st, SS1939/
A12 Serial C-6 of 4-14-43.

From: The Commander Task Force SEALFTY-O.M.
To: The Commander in Chief, U.S. TLEMT.
Via: The Commander SEVENTH FLIGHT.

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

1. The special mission executed on 5 March was accomplished in a very expeditious and efficient manner. This is being made the subject of a separate report.

2. It is unfortunate that only five contacts with suitable targets were made and that only two of these developed into attacks. The attempt to overtake and attack the TOKYO MARU on 6 March was frustrated by the plane contact. It is possible that the sampan sighted during the chase reported the position of the TAMOR.

3. The area covered by the TAMOR south of HEROIS has not been patrolled by submarines of this force recently. The observers at activity of several patrol craft in this area may be indicative of considerable enemy activity in this area.

4. The Commanding Officer, Officers and Crew of the TAMOR are congratulated on initiating the following damage on the enemy:

| Damage | Description |
|||
| 1 - Naval auxiliary | 2,500 tons. |
| 1 - Freighter | 5,000 tons. |
| Total damaged | 7,500 tons. |

1. USS TAURUS Conf.
Itr SS196/A16-3 serial
No. 7 of 27 June 1943.

FOC:
The Commander Task Force SEVENTY-ONE.
To:
The Commander in Chief, U.S. FLEET.
Via:
The Commander SEVENTY-FLEET.

Subject:
U.S.S. TAURUS - Seventh War Patrol - Comments on.

1. Forwarded. The remarks of Commander Submarine Squadron SIX are concurred in.

2. In most cases the spreads used were about one-half of what is considered good practice, however, in the final attack on the tanker on 16 June, it is considered that with 1740 track and a range of 3,000 yards either 1/4° or no spread would have been more desirable. In general it seems better to base the spread between torpedoes on a percentage of the target's length.

3. A total of five hits was made out of twenty-two torpedoes fired. There were four erratic runs but no penetrates. While the score in hits is below that considered average it is considered that the showing made was a good one for a commanding officer on his first patrol in Command. The training and experience gained should pay dividends on the TAURUS next patrol.

4. The TAURUS was distinctly handicapped by the defective condition of the SIX Radar. Every effort must be made to train operating and maintenance personnel in order that full value may be obtained from this very valuable installation.

5. The Force Commander congratulates the Commanding Officer, Officers, and crew of the TAURUS on the results of this well conducted and aggressive patrol, during which they inflicted the following damage on the enemy:

| Damage | Type | Tonnage |
||------||
| 1. AK (BISU...AU) | 4,400 tons |
| 1. AK (TAURUS...AU class) | 6,581 tons |
| 1. AK (Unidentified) | 6,000 tons |
| TOTAL... | 16,981 tons |

0551. Had attained a position about 25,000 yards ahead of convoy on its track. While chocking convoy's course prior to diving for attack, sighted smoke of a second convoy of seven ships on the opposite bearing from the first convoy. Remained on surface to determine which of the two convoys offered the best attack and the most profitable target (Ship contact #7)
0630. Determined that we were on the second convoy's track and that one of the ships was extremely large. Submerged for attack on second convoy. Own position. Lt. 16-44, O N., Long. 113-44, O E. As range decreased made out 5 medium sized freighters, one medium tanker and 17,000 ton Missin Kuru zigzagging on base course 030°. No escort.
0517. Fired five torpedoes at Missin Kuru. Saw three perfect hits amidships, torpedoes bounced off side, and one exploded in wake. No damage. Went to 200 feet to avoid being rammed by next ship in formation which, at time of firing presented a zero angle on the bow at 400 yds. Heard several muffled explosions which may have been distant depth charges, but were more probably gunfire. (Attack #3). Has losses us three fish forward and four aft.

1155
Having tracked convoy for four hours and plotted his zigzag plan on the new base course of 0900, submerged ahead and commenced approach.
1230
Convoy made a radical change of base course to the closest range being 17,000 yards. No explanation could be given for those two changes of base course. A base course of 0300 indicated for Luzon Strait. Distant, while 0900 headed for Luzon Strait.
1438
Surfaced. Manouvred to get ahead of convoy for another attack.
2035
Sighted convoy; commenced tracking for night attack. Decided in favor of night attack because convoy would be in shallow water in the entrance to Formosa Strait on the next day. Own position Lat 20-13,0 N, Long 116-08,0 E. Attempted to run to radio while tracking convoy with moderate success, occasional unreliable convoy with moderate success, 7,000 yds. Ranges could be runges were obtained up to that they were useless for obtained so infrequently that they were useless for attacking. The poor visibility frequently caused the ships to be lost at 2,500 yds. Convoy continued to zigzag at night.

Thirty-sixth Day, 24 August 1943.

0018
Attained a firing position for 90 track with stern tubes on Nissin Maru. Than the after gyro set to were out in, a shorted field in the indicating course motor caused mismatching in the automatic course and automatic firing circuits. At the same time tho target zigged and disappeared in an area of low visibility. Broke off the attack and headed for Babuyan Passage.

Subject: U.S.S. TATTY (53193) - Report of Ninth War Patrol - Corrigenda on.

1. The TATTY's ninth war patrol extended over a period of 56 days, approximately 24 or which were spent in enemy areas.

2. The first real contact occurred on the fifteenth day of the patrol when a convoy of five freighters escorted by one destroyer was sighted. Two of the first two were selected and the position attained on the first was excellent as a result of which two of the three torpedoes hit and not located for a sinking. The situation with re.ard to the second target was not so fortuitous and due to the quick counter measures by the escort could not be improved on. Two torpedoes were fired and missed probably because of the long range 2200 yards and a short track 35P. After surfacing at 1520 after this attack it is felt that the commanding officer made a mistake when he did not advise the convoy at 2144 and decided to wait for a dawn attack. Then an immediate night attack was possible. Two possible variables are: the three torpedoes lost as the ships were never sighted at dawn.

3. The next important contact that it was possible for the first to close occurred on the 33rd day of her patrol when an unsuccessful convoy of eight ships was sighted. Three of these were attacked with a total of seven torpedoes none of which did any damage. The firing position on the first two was excellent and these missiles can only be explained as either due to control errors or due to the ships being in the way of the convoy. The firing position on the third target was poor and it is felt that the firing position on the third target

FIRST ORDER REPORT
COORDINATOR
Subject: U.S.S. TACOR (35192) - Report of Tenth War Patrol - Comments on.

5. The TACOR chased this convoy for two more days
finally getting in position for a storm tube attack on the same
ship, the USS...Lt. Cora led luck: it turned in that the after
cruiser was out at the firing point. However, it is felt
that it would have been better to have used the bow and
anchor and return to port with four torpedoes re-aiming in the stern tubes.

6. The TACOR was unquestionably very much handicapped
by the loss of the use of her 3rd radar for the entire patrol as
well as by the obviously poor torpedo performance.

7. The health, spirit and morale of the crew appeared
excellent.

8. The material condition with the exception of the 3rd
radar was good. The TACOR is slated for rapid overhaul at which
time the 3rd radar will be removed.

9. It is felt that officers and men on the TACOR are to
be congratulated for having infiltrated the following dawn on the
ship:

: 1414 Still no contact. Commended high speed search to cover all target courses between 315 and 040 and speeds between 10 and 14 knots.

: 1800 Abandoned search. It is possible that we were sighted when target loomed up out of a rain squall or that target made radar contact on us while we were gaining position ahead and took advantage of the rain squall at 1300 to make a radical change of course and evade at high speed.

Surfaced.

2015
Radar contact 18,000 yards. Commenced tracking.

2030
Three radar contacts between 750 and 1200 yards. Saw nothing, so decided these contacts were on phosphorescent patches.

Initial tracking indicated targets were on northerly course, speed about 10 knots which was 5 knots greater and reverse course of convoy tracked during daylight. Decided to take position ahead and track for about two hours. (Ship contact #5). Target position: Latitude 27-15N, Longitude 125-25E.

2300
Track indicated target making unexplained changes of course.

2320
Bridge sighted ship on port bow. Sweep on FPI indicated presence of ships bearing from 330 to 150 relative. This ca.sed some confusion as observation during past two hours had shown no targets forward of 210 relative. Decided to maintain course and speed, to await developments and observe contacts on port hand. These new contacts moved down port side and opened the range. (Ship contact #6). Target position: Latitude 27-30N, Longitude 128-25E. Decided that this was another convoy or convoy which had been tracked during the day on southerly course and that radical maneuvers observed at 2300 were caused by encounter of two convoys in low visibility.

Jan. 29

0000
Resumed tracking northbound convoy. Located two wing escorts in lead. Proximity of convoy to OXN 0ZR.3U JINA prevented freedom of movement for attack from starboard flank, so had to attack from port. Decided to attack from stern of sort wing escort. Determined convoy to consist of seven ships as shown in sketch.

On rounding port wing escort, found large AK (y3) with patrol escort close on his port bow. Decided to attack this shi. first.

0156
Attained position for 90 port track with about 200 right gyro, range 1650 yards when target zigged 45° to the left at 0154.

0156
Fired two torpedoes of 6-inch (6") at range 600 yards. Immediately after the first torpedo was fired, 3° escort turned on red truck light, signaled up, and headed for TALBOR. Shooting left with full rudder, increased speed to flank. About this time saw an aircraft torpedoes hit with 6-inch cloud of smoke and fire. Target started to do down by the bow. Third torpedo was not fired because by this time TALBOR was swinging left fast. Escort kept his bow pointed straight at TALBOR and all hands on the bridge were convinced that ramming and dishing was inevitable. Opened fire with 20M gun (after gun) when escort was abeam to starboard. Was able to see numbers on bow of escort by light of tracers. Continued swinging to the left until escort passes stern distant twenty yards, then headed away from him. The 20M fire was very accurate at this close range and is considered to have prevented escort from opening fire. Escort pursued us until radar lost the convoy. Lost escort and reversed course to search for convoy.

Patrol boat maintained collision course despite our evasive maneuvers. As the patrol boat was never sighted, the presence of radar on the beach and for the patrol boat is suspected.

1. The bed plates of both high pressure air compressors were cracked all around the interior circumference. These compressors should be replaced. Temporary repairs were effected by bolting the foundations and housing together by means of angle irons.

2. Both low pressure boilers and motors were knocked off their foundations. The threads of all holding down bolts were stripped and the bolts bent. New bolts were made of brass and installed.

3. The Conning tower door frame and the frame weld were cracked, permitting water to seep through when the boat is submerged. The Conning tower arm was evidently moved, as both service pipes are out of alignment with their wells. A groaning noise is heard in the Conning tower foundation when the ship rolls in heavy seas.

4. Bot forward and aft fuel oil filling hull valves were jammed, partially open and the plugs at the top of the topside standpipes were hooked off. The resulting leakage revealed our presence to the destroyer.

5. Oil leaks developed in 5 normal fuel tank and in 5 Fuel Ballast tank. The forward leak appears to be below the water line. Fuel was transferred from these tanks to 3 and 4 fuel ballast tanks which were empty. After this transfer, no fuel leaks were observed until 20 February, on which date a cizasble slock was noticed trialling astern. At this time of writing this report, the source of this leak was not determined.

6. The operating mechanism of this supply hull valve was damaged. On surfacing after the attack, the valve was opened and could not be closed during this remainder of the patrol. Binding also exists in exhaust hull valve.

7. Number two periscope was expended useless in low power and foggy i. hi in power. Number one periscope was foggy in both powers. Both periscopes have numerous flicks in their optical systems. The upper prisms of both periscopes were cracked.

8. "Corpses in all after tubes moved forward and aft. All gyro spindles were bent and required newel. All guide studs and stop bolts were damaged. Three spare stop bolts were installed, a fourth spare was not on hand. The terminal blocks in the after torpedo firing switch box were torn loose and broken.

9. "During one depth charge explosion, a joint in the pil main vent riser was sent to spring open, admitting a large stream of water into the boat. The flanges reseated, and the leak was reduced to a trickle.

10. The antenna trunk was partially flooded causing grounds in the antenna system. Transmission was rendered unreliable for the rest of the patrol.

11. Following one attack, two serious air leaks developed in the joints between air bottles of pil bank in the forward battery well. These were located outboard and below the 1. v of the battery cell tops, making stopage difficult and a rigorous.

12. A loud noise developed in the stern planes, cause, and torpedo.

13. A quiet drain pump is a necessity. Installation of air domes on the pump will soon cause the tubes to jam. However, this pump quieted with the air domes on the pump. The noise is serious and will not be tolerated. The

15. The NM has become grounded at some time after departure from Midway rendering the fathometer inoperative during the length of the patrol.

16. Misalignment between the JX training motor and drive shafting caused noise which was distinctly audible in the sound gear. This misalignment was corrected three times on patrol but reoccurred.

17. On 20 January, the reorienting, compass-installed in Midway devolved a lock in the ball-need stun-firing box gland. As this lock could not be repaired by ship's force, the reorientation system was cross-connected with the #1 air conditioning unit.

(1) RADIO

The material condition of the radio equipment was good except for the partially gloved antenna trunk caused by depth charging. This resulted in zero grounds on all antennae. Reception remained good, but transmission was impossible until the trunk was fired out with a blower and CO₂ absorber. The l.s.k., however, could not be stopped, and a low reading recorder after each dive.

On station, all mass-gage were received in spite of severe interference by the enemy. Throughout the patrol, they effectively blocked the first schedule signal immediately on all frequencies. The second and third schedules were received with practically no interference.

Enroute, the frequencies afforded the best reception were 16.68 and 12375 Kcs. On station the reception was best on 4525 Kcs from 0600 to 1800 G.C.T. and on 9.90 Kcs from 1800 to 0600 G.C.T. During the test period of 15 to 20 January, no sporadic gl in signal strength was noted.

After the antenna trunk was partly flooded, no receiving stations could be raised with magnet readings of less than one neapth on the antenna in spite of persistent c.illing and blind transmissions.

On 19 February, after leaving the area it was still impossible to raise NPH, so an attempt was made to transmit on 8410 Kcs. An invalid antenna was received from the first call and a prompt receipt for the transmission. However, no acknowledgment was received from C.T.F. 17 over the regular schedule.

Sufficient fresh vegetable and fresh frozen vegetables can be carried to supply the needs for the greater part of a patrol. In view of the possibility of refrigeration failure, it is necessary to carry a good reserve of canned foods. The lettuce, cabbage, potatoes and onions supplied were of superior quality. The lettuce and cabbage lasted for three weeks, the onions throughout the patrol, and the potatoes until 23 February.

(Q) PERSONNEL

The conduct of the officers and crew during the patrol and during the severe depth charging was in keeping with the best traditions of the submarine service.

Much of the credit for the success of all attacks is attributed to the fine teamwork of the fire control party consisting of:
   - Lt. W.B. WOOD, USN, Plotting officer
   - Lt. (jg) V.L. VITUCCI, USN, R.D.R. officer
   - Lt. (jg), W.... 30Mast, USNR, T.D.C. officer.

U.S.S. TARBOR - REPORT OF WITNESS: MR. PATROL

(U) REMARKS

A study of numerous recent patrol reports reveals that the advent of the Hark XIV-3A torpedoes and the re-lease of J radar is leading to the development of a new night attack doctrine which involves firing at ranges between 2500 and 3000 yards. Endorsements of these patrols have condoned the practice when successful but have almost inscrutably pointed out that the attack should have been launched from closer ranges.

Close range shots at night were considered necessary and sought after by all submarines to obtain hits prior to the development of the Hark XIV-3A torpedo and the Sd radar. At that time failure to hit at night was thought to be a result of control errors and not exploder failures.

An attack initiated at a range of 2500 yards has many advantages over one initiated at 1500 yards.

As is well known, the primary advantage of a submarine submerged are its ability to attack undetected and to increase depth to avoid collision when operating at close ranges. When maneuvering on the surface at night, a submarine sacrifices these advantages. An unexpected zig on the part of the target when the range is 1800 yards is almost certain to place the submarine 600 or 700 yards below the target. In this position, detection is almost certain and evasive maneuvers almost impossible if there is an escort astern of the target. Should the submarine succeed in firing undetected inside of 1500 yards it must present its beam to the target and escort, if there is one astern, at ranges of 700 to 400 yards depending on the submarine's speed when firing. The submarine is then forced to dive and thereby sacrifices an opportunity to return the attack.

Careful tracking with the radar will enable the submarine to determine target's speed within 0.2 knots and course within 2 degrees. The zig plan can be plotted and length of zigs determined within 30 seconds. With this information it is possible to select a firing position which will offer the chance of obtaining hits on multiple targets.

ENCLOSURE (A) (34)

— page 306 —
2800 yards the submarine will be free to maneuver following unexpected course changes of the target during the approach, fire undetected, and be sure of hits. The turn away can then be completed before the first torpedo reaches the target. The minimum range to the escort will be about 2,000 yards and the chances to evade on the surface for another attack on remaining ships will be increased about 150%.

Training:
It is recommended that escorted targets be used, if available, for night attacks during the training period and that the tracking period be lengthened. Multiple targets of approximately the same size present the most difficult tracking problem as radar operators lose the target when on ship maneuvers. Target setups which would enable radar operators to gain experience in multiple target tracking would be invaluable.

Torpedoes:
Although it is common practice to withdraw gyro spindles when tubes are not in use, this was not available to accomplish this prior to the depth charge attack on 3 February. Examination of the damaged spindles and stop bolts revealed that it was the spindles and not the stop bolts which prevented the torpedoes from moving enough to actuate the starting levers and cause three hot runs at most inopportune time.

Traffic Routes:
Three convoys passed between OXYGEN, BU JIH, and YORON JIMA.

Energy Rad.:
See "ANTI-SUBMARINE RADIUS".

The black lighting of the T.D.C. is considered excellent and necessary. The efficiency of this lighting would be improved if it was more rugged and was installed inside the face of the T.D.C.

1. The ninth war patrol of the TAILOR was made in the East China sea. Aggressive and well-executed attacks were made on four ships, resulting in sinking of three and the damaging and probable sinking of another. In spite of a severe depth charge attack following the second torpedo attack, the patrol was continues until provisions of operation order had been carried out.

2. A nice position for attack on the last ship of a three-ship convoy with four escorts had been obtained when an unexpected zig toward placed TAILOR in close quarters with both the target and one escort. Two torpedoes were fired at 600 yards! range, resulting in two hits and sinking of a 7,000-ton unidentified freighter. The escort attempted to ram TAILOR and might have succeeded but for the timely use of the after 20 12. gun which undoubtedly created a diversion, especially with firing range of about 70 yards. Had decision to dive been made after firing torpedoes, ramming might have occurred, and a severe depth charging would have been almost inevitable.

ATTACK #2

In an attack on a freighter and a tanker with one destroyer escorting, two hits were obtained in the freighter and one in the tanker. Breaking up noises subsequently heard at a range of about 4,000 yards from position of attack would indicate that the freighter sank. The explosion and huge fire from one

Subject: The ninth war patrol of the TAMOR was conducted in the best China Sea.
1. In spite of very strong enemy anti-submarine measures the TAMOR made three very aggressive and successful attacks, inflicting severe damage upon the enemy. The Commanding Officer's skill in maneuvering his ship while on the surface to avoid running by escort vessels is commendable. The skill displayed in effecting repairs after a very severe depth charging is worthy of praise.
2. Because of the Commanding Officer's close observation of the damage to the fiercely burning tanker and the subsequent breaking-up noises heard, it is believed that she sank. Accordingly, credit is given for sinking both the tanker and the freighter.
3. This patrol is designated as successful for Combat Insignia Award.
4. The Commander Submarine Force, Pacific Fleet, congratulates the Commanding Officer, officers, and crew on this most aggressive and very successful war patrol. The TAMOR is credited with inflicting the following damage upon the enemy.
