2- USS ANGLER

Prior to leaving on her fourth patrol, Lieutenant Commander Olson was relieved by Lieutenant Commander Franklin G. Hess, USN, as commanding officer. The fourth patrol of the ANGLER was spent in the South China sea in company with the USS FLASHER and USS CREVILLE. A convoy of ten large cargo ships, an escort carrier and numerous smaller escorts were sighted and trailed. Late that night the PLANESHER made the first attack, sinking several of the transports and setting fire to others. The carrier left the scene of attack and the ANGLER closed in on the remainder of the force.

Attacking on the surface, the ANGLER sent another Jap ship to the bottom before one of the escorts sighted her in the light of early morning and began sending explosives in her direction. Submerging, the ANGLER sent another ship to torpedoes into the enemy force and, after the CREVILLE's attack, only one of the original ten transports remained afloat, and it wasn't in the best of health."

Several days later another convoy was sighted, but the ANGLER was unable to close to torpedo range so no ships were sunk.

After a refit in Australia, the ANGLER was ready for her fifth war patrol. This patrol was conducted in the Mindanao Sea, Sulu Sea, and South China Sea during the months of September and October 1944. During her patrol, the ANGLER did reconnaissance work around Leyte and Samar prior to the invasion by our forces. A few days before the invasion, the ANGLER left the Mindanao Sea and patrolled off Puerto Princesa, Palawan, sighted several merchant ships, but was unable to attack because of unsatisfactory conditions.

From Puerto Princesa the ANGLER proceeded to Cape Calabric on the Northern tip of Mindoro, sighting a convoy and sinking a troop transport enroute. Arrival of Mindoro seemed to be the signal for the starting of general fleet maneuvers. Everytime the periscope was raised a destroyer of cruiser, making maximum speed, would go by. Their haste saved them from attack.

While cruising along at slow speed on an inky-black night in the South China Sea the officer of the deck reported hearing wierd-screams from the water. The ANGLER played a game of hide and seek, trying to locate the origin of the sound, but it was not until after daylight when numerous Jap soldiers and sailors were sighted in the water. Some were dead, some alive and others about half-way between. The ANGLER picked up several for questioning, one being an Army lieutenant who readily admitted at that time that "Japan had lost the war."

While proceeding toward the northern end of Palawan Passage, the ANGLER contacted a large enemy task force, which, it was later learned, consisted of five battleships, eight cruisers, and thirteen destroyers. The ANGLER trailed this force and kept the U.S. Fleet informed of its location. This force was later engaged by the U.S. Fleet in the Battle of the Sibuyan Sea. It was while trailing this task force that the ANGLER also ran across a convoy of merchant ships. However, the ANGLER kept to the more important duty of trailing the task force so that it might not interfere with the plan of the allied invasion program.

3- USS ANGLER

After having found where the task force was bound, the ANGLER retired from the scene to return to Australia for necessary repairs. It was at the end of this patrol that Lieutenant Commander Howard Bissell, Jr., USNR, relieved Lieutenant Commander Hess as commanding officer. Lieutenant Commander Bissell was one of the first reserve officers to assume command of a fleet-type submarine.

It was on her 6th patrol in the South China Sea that the ANGLER was informed that the USS BERGALL, another U.S. submarine, had been damaged during a night surface encounter with two Jap cruisers, and was unable to submerge. The BERGALL was less than a hundred miles from Singapore, and over a thousand miles from the nearest allied forces. The ANGLER was ordered to contact the BERGALL, remove her crew and torpedo her to prevent capture by enemy forces.

It was in December of 1944 that the ANGLER contacted the BERGALL and removed all but thirty of her crew. The captain, Commander Hyde, felt his submarine could be saved and decided to run the gauntlet of the Jap held islands with the ANGLER standing by in case of trouble.

Never out of sight of enemy held islands, through Karimata St. ait, the Java Sea, Lombok Strait, and on down to Australia, always fearful of spying eyes from enemy aircraft or surface ships, the crippled sub and her escort pulled safely into friendly waters, where the BERGALL was repaired and lived to sting the enemy again.

One of the highlights in every submarine patrol from western Australia was the passage through Lombok Strait, a long narrow pass between the islands of Bali and Lombok, with the small island of Nusa Besar thrown in as an added obstacle. After having delivered the BERGALL to port, the ANGLER was once again enroute to her patrol area. It was Christmas Eve and the third Sunday night in succession that the ANGLER had gone through this hazardous area. A bright moon was shining, but evidently the Japs had no idea of the Christian observance, for just after entering the strait, the entire beach of shore batteries opened fire on the ANGLER. A patrol boat eased into the submarines path and opened fire and an Airplane zoomed over-head. However, the ANGLER ploughed ahead and escaped without so much as a scratch to hold Christmas services.

Shortly following this encounter the ANGLER began her long trek back to San Francisco for a much needed overhaul. She set out again for the Western Pacific on 18 May 1945. In the latter part of June, the ANGLER departed from Guam in company with seven other submarines, enroute to conduct anti-shipping sweeps in advance of the Third Fleet, for permitting the fleet to approach the coast of Honshu undetected. After completion of this duty, the ANGLER selected as its next target an enemy radar and army installation on the island of Kinkasan off the coast of Honshu. The first shell fired went right into the front door of the administration building of the Nip's army headquarters with-out even bothering to knock. Others damaged surrounding properties.

4- USS ANGLER

After such success in this first bombardment, the ANGLER turned to Tomakomi, a city of 30,000 population on the island of Hokkaido. Fifty rounds of high explosives were scattered through the manufacturing section of this town with devastating results.

Early in August of 1945 the ANGLER made rendezvous with two other U.S. Subs, the THORNBACK and SEA POACHER and formulated plans for a joint bombardment of several towns on the southern coast of Hokkaido. Several towns were shelled but soon all ammunition was expended and the ANGLER departed for Midway Island and there celebrated the end of the war.

By Directive dated January 1947, USS ANGLER (SS 240) was placed out of commission, in reserve, attached to the U.S. Atlantic Reserve Fleet.

Target dead ahead, angle on bow 300 starboard - at 2500 yards target turned and gave zero angle on bow. Went ahead flank and swung port, closing to attack port. Port was a destroyer escort. Got clear on his target. Distance 4,000 yards and decided to attack damaged target at stern of destroyer.

0309 K
Swung left, came in for 90 port track and at 2,100 yards fired three at crippled freighter, while doing so determined destroyer was actually very small tanker. Came left further (tow TDC setup) and fired three at small tanker (Depth 8 foot). All torpedoes missed. Continued swinging left to parallel small tanker's course. Distance from track was 900 yards which illustrates effectiveness of groy escouflage (Torpedo attack #2). (See remarks under Attack #2).

1352  DATE 27 Jan., 1944  Lat. 23-58 N  Long. 145-50 E

Target Data - Damage Inflicted

Sunk One (1) patrol-troop fishing boat approximately 150-200 tons with rising sun flag and blue naval old fashion anchor painted on both bows forward of the flag. Name ______. Established by questioning prisoner.

Damage determined by: Saw target sink.

Details of Action

Submerged immediately after contact and began observing target's actions. Neither the high porpoise or the 3d had seen this boat but the patrol boat had undoubtedly seen us and started circling around us at 2½ to 3½ miles, decided if necessary to surface and get clear, we could out run him in the flat sea. At that time we noticed his unusually large radio antenna and decided we had already been reported, so at 1315 went to stations for battle surface.

1325 Battle surfaced and closed range to about 3500 yards and commenced firing with the 4 inch gun. Target started maneuvering and starting around like a water bug after each splash, so decided he had no deck gun. The tripod machine gun which was visible on the deck house fired at us but all splashes were about 1000-1500 yards short. We had closed the range to 2000 yards when the 4 inch gun got a direct hit on the deck house, starting a fire which they later put out. Swung left to bring all 20mm and 30 cal., guns to bear and raked him for and aft, over and under, with everything we had. While doing this all sorts of things happened. Target was out of control, both 20mm guns jammed, the 4 inch gun stuck in train and the 4 inch sights fogged.

1349 Cloaked the decks and dove to get re-organized. While submerged saw a "Heaven - scant" rain storm coming from the west.

— page 30 —
1357 Battle surface and ran into the rain storm while getting set up for the next round. We felt secure in the rain storm with the SD and PPI manned, so we took our time to get everything ready for another go at him. At this time the SJ had the target nicely at 3500 yards.

1400 Came around and closed to 1500 yards and gave him everything we had which started another fire, so pulled clear to watch the results. The target was now dead in the water and we thought everyone surely must have been killed. The second fire went out while target lay to rolling in the seas which had picked up during the rain storm. Visibility now about 2000 yards.

1424 Swung around and passed the target aboard to starboard 800 yards and obtained numerous 20mm hits and three 4 inch hits. The target showed no signs of sinking or burning although numerous holes could be seen in the sides, and no life could be observed on board. Dedicated to take a closer look. So with the after 20mm and the 30 cal., plus tonny guns manned, ran down his starboard side about 400 yards. Saw one Jap run forward (later named Jo as in Tojo) so opened fire. As we pulled clear a fire had started in the dock house and soon spread to the after part of the target. Circled at about 1000 yards observing the target burn.

1524 Target began to sink after we had observed two violent explosions and smashing, and one equally violent explosion aft. All explosions appeared to be fuel oil tanks except a minor explosion which grew off a white smoke possibly from pyrotechnics. The target was sinking slowly by the storm.

1. The First War Patrol of the INGLER was of short duration. Eliminating the voyage report period of 4 days at midday, 22 days were spent enroute to and return from area with out having reached the patrol area. The patrol was to have terminated at Promontorio, but the Commander Officer returned to midday when he considered that the fuel remaining prevented carrying out the provisions of the operation order.

2. Only two contacts were made, one a patrol saipan and the other, a four ship, unescorted convoy, which was later joined by three escorts. Both contacts resulted in attacks.

3. (a) ...fter trickling for over 4 hours and trying to determine the composition of a convoy, three torpedoes were fired at a large tanker in a north surface attack. One hit was seen on the tanker, which exploded and sank, and a hit was made on an overlapping ship. ...fter retirement to 5000 yards and relocating, a second approach was made, firing three torpedoes at the crippled freighter. ...ll missed. ...fter noting that what had been thought to be a destroyer escort was actually a small tanker, three Mark XVIII torpedoes were fired when this and a medium tanker, at a greater range, were overlapping. Two of these, set at 6 feet, went under the small tanker, but two hits were obtained on the medium tanker, which stopped and in four minutes disappeared from the radar screen. The arrival of three escorts prevented further attack.

1. The ANGLER's first war patrol was spent enroute to areas under the operational control of the Commander Task Force Seventy-One. Prior to her arrival in those areas, the ANGLER developed structural noises which would make silent running prohibitive. Because of this the ANGLER decided to return to Midway for voyage repairs.

2. While enroute to the area, the ANGLER contacted one patrol trawler and one convoy. The trawler was destroyed by gunfire, and the convoy aggressively attacked during a night running battle.

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

4. The Commander Submarine Force, Pacific Fleet, corrctulates the Commanding Officer, officers, and crew for inflicting the following dangers upon the enemy:

A. PROLOGUE

Arrived Midway, T.H., 4 February, 1944 for purpose of voyage repairs and reload of torpedoes, 4" ammunition, fuel and stores, in accordance with ComSubPac dispatch. Due to short period involved in first patrol no reoperation period was granted. The crew was granted two days liberty'off the boat, one section remained aboard at all times.

On 12 February, 1944 we were ready for sea in all respects except for loading of four Mk. 18 torpedoes, which were to arrive on the Trout, and awaiting operation order which was to arrive on the Rock. (Both were outside Midway channel entrance at this time, but could not enter'because of weather.) 14 February, 1944 torpedoes and operation order arrived - torpedoes loaded and we were ready in all respects at 2400 February 14, 1944.

FIRE CONTROL AND TORPEDO DATA

Original contact was made while on the surface, simultaneously with radar and by sight. The target was trekked by radar and TDC until a solution was obtained. An end run was made until we reached a favorable position and then turned to radar depth - began using radar ranges and poriscope bearings. Solution continued to check so went to 63° and continued checking TDC with poriscope bearing until torpedo run reached 1800 yards at which time we fired 4 torpedoes (10 divergent spread). No hits - target apparently of very shallow draft as torpedoes were not at six feet.

Night (Black) lighting as installed in the TDC is excellent. Night lighting as installed in #1 poriscope is useless - this ship uses a rod flashlight for reading bearings on the luminous roversod azimuth scale.

P. HEALTH, FOOD AND HYGIENICITY

In gonoral the food was below the standard to which the submarine service has become accustomed. This was due mainly to our inxcorpionced cooks and the failure of the yacht supply which eliminated broad from our diet for most of the patrol. In gonoral the health of the crew was excellent. About half way through the patrol our fresh water became contaminated (cause still unknown) which caused numerous cases of scvoro nausea. During the last week of the patrol this nausea was so pronounced that 1/3 officers and crew could not hold food in their stomachs. The cause of this contamination is being investigated.

Q. PERSONNEL

In gonoral all hands performed their duties in keeping with the highest standards of the submarine service. Special mention is due - NEDLINGER, Loo Martin, #648-79-13, PhMlE, V-6 USNR, whose performance of duty was outstanding and contributed materially to the successful completion of our special mission. Special credit is due - HEART, Marvin Richard, #279-67-06, CEC2, USN, whose performance of duty in connection with our special mission was also outstanding.

The Commander SEVENTH FLEET.

Subject: U.S.S. ANGLER (SS240) - Report of Second War Patrol -
1. The second war patrol of the U.S.S. ANGLER was conducted on East Coast of PHILIPPINES, MIDANAO and SIJUAN area, enroute from MIDWAY to FUKAHATU, AUSTRALIA, during the period 15 February 1944 to 9 April 1944. Out of a total of fifty-five days on patrol, twenty-five days were spent in assigned areas.

2. The one torpedo attack made was a submerged radar periscope attack, on a bright moonlight night. Torpedoes had a run of 1800 yards, and the data appeared excellent. All torpedoes were set at six feet and all missed. A special mission was successfully completed.

3. The ANGLER returned in good material condition and it is expected that she can be refitted in the normal time. The conversion of No. 4 Main Bellast Tank to a Fuel Oil Bellast Tank will be accomplished during this refit. No specific cause for the fresh water contamination has been found. Several samples of water were analysed. The physical and bacteriological contents were well within the prescribed limits. The fresh water tank was scraped, cleaned, and then given a cement wash, following which the whole system was thoroughly flushed out.

4. The Squadron Commander congratulates the Commanding Officer, officers and crew on the successful completion of their difficult mission.

12 May 1944 (Cont'd.)
2030 Closed range to 6,500 yards - nothing in sight, decided target must be small patrol boat.
2035 Stopped - Contingued tracking target - course is definitely 095°(T), speed 9.5 knots. Plotted target's positions on the chart and found he is headed to pass close aboard southern edge of Sebesi Island.
2100 Lost target - still on course 095°(T), speed 9.5 - range 10,400 yards.
2103 Scoured from battle stations after deciding not to attack since target is apparently not suitable for torpedo target. Did not desire to disclose our presence in Sunda Strait and thus jeopardize our reconnaissance mission.
2110 Small pip at 180°(T), range 2400 yards, closing radially at 1800 yds radar showed two pips - TDC tracking showed course 350°(T), speed 15 kts - range continued to close until we + 19 kts. When range was 1100 yds lookouts e that two large wakes stern, verified by Captain. Then range had opened to 1500 yards at.
2120 Began reversing course slowly to reach in order to headed for open water and run by line pips. While swinging right radar picked up two more pips on the bow, range 3000 yards, continued swing to right to put those last two pips on the port quarter, while range closed rapidly to 1400 yards, bearing drawing aft.
2230 On reverse course, 180°(T), sighted wake dead astern.
2250 Lost contact. At this time felt at least four and possibly six MET's were in area, and since moon was due to rise within the hour decided to haul clear, since it seemed apparent we were not detected.
2330 Slowed, resumed patrol of southern approaches to Sebesi Channel.

20 May 1944 (Cont'd.)
: 1717 It begins to look like a long range shot now - target is steady on course 0700(T), so am running at standard speed between each observation in order to close the track. No escort in sight.

: 1726 Sighted escort about one (1) mile astern on target's starboard quarter. Escort is echo ranging continously shifting from long to short scale search and back again but does not train sound head around. Target is still steady on course 070°(T) at 8 knots.

: 1747 Still no change in set up - target definitely a transport. Gun platform aft was crowded with 25 or 30 people. Some wearing white skivie shirts others in a darker uniform. The amidships deck railings were crowded but only the darker uniform was in sight there.

: 1806 Unable to close target any more, and with set up check perfectly on TDC and plot. (During firing sound said target had speeded up but it was too late to do anything about it).

: 1808 Fired four (4) torpedoes.

: 1809 Right full rudder, all ahead full.

: 1810 Heard first hit - all stop, raised periscope in time to see a second torpedo hit target just aft of amidship. This fish did not explode but sent a column of water and spray into the air about 25 to 30 feet. Believe this was caused by air flask exploding.

: 1811 Escort is giving zero angle on the bow now so continued swing to the right and with angle on the bow zero, range 1800 yards, fired three (3) torpedoes at him from the stern, using 1/4 degree divergent spread, depth 6 feet, all missed; swung around for last look at target before going deep, sound reports target's screws stopped.

: 1812 Rigged for silent running, changed depth to 350 feet.

: 1813 First depth charge.

Enclosure (A) -8-

: 1814 Second depth charge, third depth charge.
: 1815 Fourth, fifth depth charge - close and above.
: 1816 Sixth, seventh, eighth depth charges.
: 1819 Ninth depth charge.
: 1820 Tenth depth charge.

At this time we have a 180 temperature gradient at 20 feet which started at 80 feet - I believe the escort is now contact with us and it was never rejected, although it was through the usual routine of stopping to listen, etc., when target was lost seen the stern was ahead, but I was up to the first gun platform and it had closed at 180 feet list, so our engine had the escort's early departure was not critical to pick up survivors. After the last depth charge sound operator reported two muffled explosions (affirmatively not depth charges) interrupted with sinking ship noises.

: 2048 Surfaced oil clear, SD radar set in contact with, clearing visibility on four miles.

: 2155 Secured from battle situation: three aircraft now had several cases of nausea, experience of the Japanese ships at this time I felt it might be a no surprise silence and the attendant heat etc., there is the fact we never excessive and the duration of this run is about six minutes not long enough to cause such general discomfort.

Time 1808 Date May 20, 1944 Lat. 05-40-20 S Long. 105-27-35 I

Torpedo Data - Damage Inflicted

Description:
The target was similar in all respects to the YUKI MURU shown on page 213 of ONI 2087. The target was escorted by a PC Class No. 3-39 submarine chaser which was on the target's starboard quarter, distant 2000 yards. The sea was calm and the visibility unlimited. The target and escort both had a recent paint job of gray war color which reflected the sunlight.

Ship Sunk: One (1) AP 6000 Similar to YUKI MURU page 213 ONI 2087
Ships Damaged or None
Probably Sunk None

Damage Determined By: When last seen the ship was sinking by the stern with after deck awash up to the after gun platform. One hit was timed and one hit was seen.

Target Draft 15' Course 070°(T) Speed 8 knots
Range at firing 3000 yards.

OWN SHIP DATA

Speed 1/3 Course 010°(T) Depth 64 ft. Angle 0

FIRE CONTROL AND TORPEDO DATA

Type Attack: Attack No. 1 was a day periscope attack. The two masts of the target were sighted, bearing 285°(T). Our own ships course was changed to 285°(T) and the approach started. Shortly after the target was picked up visually, long scale pinching was detected on the sound gpser but no escort could be seen. The initial range was estimated at about 14000 yards. It was not until we had closed to nearly 8000 yards that the escort was seen on the target's starboard quarter, distance about 2000 yards. According to plot and T.D.C. the target was on a steady course of 070°(T), speed 8 knots. The escort was echo rancing continually but it is not known definitely whether or not we were detected before firing. The escort did not change course before firing but a large puff of black smoke was seen to

come from the targets stack a few minutes before firing. The
target may have speeded up. The T.D.C. did not show any change
in speed. The range was closed to 3000 yards and with a 117
degree starboard angle on the bow end a 3 degree left gyro angle
it was decided to fire four torpedoes forward. The depth
setting was six feet. A straight spread was used, with the

1. MINES.
No mines were encountered. However, after studying the courses followed by ship contacts #1 and #5, it seems very likely that the 'passes north of Sebesi and Sebuku are closed by mines.

: 2. ANTI-SUMMARINE MEASURES AND EVASION TACTICS.
For Evasion Tactics we went to 350 feet, taking advantage of an 180° gradient and ran silent on a steady course to clear vicinity as rapidly as possible.

: 3. MAJOR DEFECTS AND DAMAGE.
1. May 8 - #1 L.P. blower (turb) had to be secured after five minutes of operation due to excessive lube oil temperature. Inspection revealed that the forward bearing, which was replaced by relief crew, had begun to "wipe" due to there being no clearance. Bearing was scraped and replaced.

2. May 9 - #1 H.P. air compressor, #3 intercooler coil carried away. Coil was silver soldered and replaced. Compressor operated until May 22 when it carried away again. Crack in coil was about 1½" long on May 9. It had been extended about 3/4" by May 22.

2(a). May 9 - Steering motor bearings became excessively hot causing the motor casing to heat up. Inspection revealed that the magnetic brake discs had been rubbing while motor was in operation. Brake was removed and the motor and bearings cooled off appreciably.

K. MAJOR DEFECTS AND D.M.GE. (Cont'd.)

3. May 15 - Ball bearings on North rotor of master gyro carried away. Inspection revealed that it was not due to lack of lubrication, but due to a faulty bearing. Repaired in about eight hours. On May 16 gyro was secured to pump down vacuum and to renew vertical rotor case bearing.

4. May 24 - #1 Fuel Oil Purifier out of commission. The drag ferrule, male and female parts disintegrated. Drag ferrule was taken from L.O. purifier and F.O. purifier put back in operation. The purifier had a total of 500 hours operation, and had been completely overhauled only 56 hours previous to breakdown.

L. RADIO.

No comment.

M. RAILER.

SD-4 - No planes were picked up to the time of the attack.

SJ-1 - Excellent operation until the time of the attack. Then numerous troubles have arisen and could not be seen out of commission most of the time with incriminating trouble.

N. SOUND GEAR AND SOUND CONDITIONS.

SUPERSONIC - Sound conditions proved to be very good on the only target contacted. The target was picked up at a range of approximately 11,000 yards.

SONIC - The JF-1 sound apparatus is useless to this vessel inasmuch as we are equipped with Portsmouth type train which cannot be moved during deep submergence. This type train is being replaced with Mare Island types but as yet this vessel has not been so equipped.

Depth Charge Indicator worked very well and is always believed to be accurate. No depth charges registered as being below this vessel which was at a depth of 350 feet.

Enclosure (A) - 18 -

— page 91 —
0. DENSITY LAYERS.
A remarkable temperature gradient was noted at the point of torpedo attacks #1 and #2, position 05-40-20 S, 105-27-35 E. The gradient started at 80 feet and at 350 feet amounted to 18 degrees. This gradient was so effective that the escort was never able to make sound contact with us.

P. HEALTH, FOOD, AND HABITABILITY.
The food was in general good. Health and habitability were the limiting factors of this patrol, since all hands aboard were poisoned from some unknown source. The cause of the poisoning is under investigation.

Q. PERSONNEL.
The performance of duty by all officers and men met with the highest standards of the submarine service and leaves nothing to be desired.

REPORT OF THIRD WAR PATROL

U. REMARKS.

This patrol was terminated 22 May, 1944 by the Commanding Officer when it was felt there was grave danger of losing the boat due to the large amount of sickness on board, if the patrol were continued.

On 24 May, 1944 J. G. Bateman, Lt(MC), USN was transferred to the USS .NGLER from the USS OREVILLE at sea and immediately took over the treatment of the sick. The condition of the crew and officers during the period can best be stated by quoting direct from his report to the Commanding Officer. His report is quoted herewith in full:

"On boarding the U.S.S. .NGLER, 24 May, 1944 forty-one of the personnel were found to be ill, many of the men being sickly. The captain's report of the crew were still convulsive. There were three men with pneumonia, eight of them were suffering from a dyspnoea, caused by pneumonia. These men were given intravenous fluids, and were given a diet of soft diet, forcing the patient to eat as much as in the past.

The following day (25 May) improvement in the condition of the patients was noted. Two of the men were able to get up this date. The rest and fresh air worked considerable improvement among the crew. Even those men who had not been ill were benefited, as they had been under the strain of standing additional watches. On the following day (27 May) almost all of the men were back to eating a regular diet.

Subject: U.S.S. ANGLER (SS2/0) - Report of Third War Patrol.

1. The Third War Patrol of the ANGLER was of 27 days duration, 13 of which were spent in the assumed patrol area covering the southern approaches to Sunda Strait. The patrol was terminated early due to a sudden outbreak of poisoning which incapacitated most of the officers and crew; it is regretted that this serious illness occurred.

2. Seven torpedoes were expended in submerged attacks on the only worthwhile torpedo targets contacted, an AP of about 6000 tons with a single PG type escort. A four torpedo spread was fired at the AP on a favorable track when ANGLER was unable to close the range within 3000 yards. Two hits were observed but the commanding officer is of the opinion that one warhead failed to explode. Three torpedoes were then fired in a "down the "troch" attack upon the escort at a range of 1000 yards. All torpedoes missed due to under running or maneuvers of the target. ANGLER evaded the subsequent depth charging under an unusual temperature gradient of 1° degrees.

3. The cruises for the serious illness which affected the personnel of the ANGLER crew being investigated and will be covered by separate report. Upon arrival the personnel were still in a weakened condition and were seriously in need of rest and reparation. They were sent to reoperation centers about 24 hours after arrival.

4. The ANGLER returned in good material condition; all material deficiencies will be corrected during refit period.

5. The Commanding Officer, Officers and Crew are congratulated for having inflicted damage on the enemy.

0824: Sighted smoke bearing 1500 T. Since the heaviest smoker had been on the left hand side of the convoy, this bearing looked pretty good, but decided to come to 1100 T to be sure.

0831: Sound heard pinging from 3 sources, bearings 1300 to 1700 T.

0835: Went to battle stations.

083C: Sound reported heavy scores bearing 1300 T.

0851: Periscope depth, and it is on the bow 90 port. Convoy consisted of 1 escort carrier, 5 freighters all new and of about 7-8,000 tons and 2 destroyer escorts in sight.

0854: Back to 100 feet tryline to close, Navis has been sight each look.

It appears that the convoy has changed its base course to 0200 T and speed is now 10 knots. A possible explanation may be that he has been making gradual changes of base course to clear Scarborough Shoals, and has now settled down. This closest range obtained on any slip was on the port quarter Fubuki escort, at 7,000 yards.

: 0213  There was a tremendous explosion in the convoy, and one of the ships was afire from stem to stern. Minor explosions continued for sometime, and finally the ship must have gone down leaving oil or gas burning on the surface. It looked like a gasoline explosion.

This attack scattered the convoy so we picked out the nearest and biggest, and continued trying to get in position.

: 0317  Sounded battle stations. Convoy is forming up again and we are ahead.
: 0330  At range of 12,000 yards we have 5 large ships in sight between us and the flow of the explosion. All ships are milling around, no two on the same course.

0406 Heard 3 depth charges not very close, over-head and astern.
We could hear scores all around and passing back and forth overhead but no echo ranging. I believe all the escorts had gone after the Flasher on the first attack.
0435 Sound reported torpedoes running 275 T. Heard two explosions. Also echo-ranging from ahead, we were on course 100 T.
0436 Sound heard loud breaking up noises from vicinity of convoy, these could also be heard through the hull. From this time until
0543 We could hear echo ranging and scores in the vicinity but we were not picked up.

Patroling 10 miles off Point Rena, Luzon, P.I., U.S.S. Crevalle to north.

0215 (Shin Contact #9) 3T Radar contact bearing 0430, range 12,000-yards; commenced tracking. Target on course 1600 T; speed 9 knots. Contact was fading in and out, and appeared to be small, so at

0250 Secured tracking and resumed patrol.

0425 Submerged 4 miles off Rena Point, closed coast to 3 miles and commenced patrolling on north and south line.

0659 Sound reported faint echo-ranging bearing 2500 T. Changed course to 2500 T.

0715 Bearing of echo ranging changed to 2600 T, so came to course 2800 T. At this time we were in a heavy rain squall, visibility 1500 yards. The echo ranging sounded very distant.

0746 (Shi Contact #10) The weather cleared and the sea was full of ships, the tops of 12 ships and one escort were in sight, but the last ship of the convoy bore 2700 T, range 15,000 yards, and the bow 900 starboard. It looks like we were patrolling in too close. All of the ships in sight appeared to be about 4,000 to 5,000 ton freighters, with single tall stacks and stick masts forward and aft. The last ship looked like a landing boat carrier similar to the Hakusa Haru.

The convoy appeared to be on course 0000 t, speed 8.

0753 Since it was impossible to close any of the ships for an attack decided to head out from the coast, trail the convoy and try to regain contact for a night attack.

0941 Hard two explosions, these sounded very much like torpedoes.

1543 Surfaced, and started searching for convoy,
   - on course that would cover his probable
   - routes and bring us off Viqan at his probable time of arrival.

1930 Sent a message to U.S.S. Aspro and U.S.S.
   - Crevalle telling them where I was and
   - what I was doin'. The Aspro did not
   - receive it because we are in her area.

2300 Commenced patrolling 12-miles off Viqan,
   - Luzon, F. I.

July 29, 1944

Patrolling off Viqan, P. I. covering
   - inshore routes.

0100 (Ship Contact #11) SJ Racar contact
   - beariig 0530 T range 19,000 yards, single
   - target. Commenced tracking. Target tracked
   - on steady course of 1980 T speed 9 knots.

0200 Went to Battle Stations and started closing.

0229 With racar range of 6,000 yards and a good
   - horizon in the direction of the target,
   - nothing could be seen from the bridge so
   - broke off approach and resumed patrolling.
   - It is believed this was a very small ship
   - of some sort, possibly a patrol boat. At
   - times it seems the SJ works almost too
   - well.

1. ATTACK DATA
   - Torpedo Attack No. 2
   - Date: 26 July 1944
   - Patrol No. IV
   - Lat. 16-30 N
   - Long. 117-57 E

TARGET DATA - DANGER INFLICTED

Description: Similar to the Komaki Maru, 8,033 tons, page 62, ONI 206 J revised. This attack took place immediately after attack number one. This target was the nearest ship on the starboard bow. All conditions apply to the first attack apply to this attack.

Ship's Sunk: None.

Ship's damaged and probably sunk: None.

Damage determined by: None.

Target Draft: 27' Course: 140° T Speed: 11 Range: 2,400 yds.

ORIGIN SHIP DATA

Course: 030° T Depth: Surface

TYPE ATTACK: Surface - Six-tank Racer. As soon as attack number one was completed the stern tubes were brought to bear on the closest ship on the starboard bow. During the time we turned to starboard, when we were 1,600 yards and he turned to starboard, when we were settled on our course he presented an 60° port angle on the bow and agreed to have steaded on his course.

With range of 2,400 yards commenced firing the stern tubes. About a minute after the stern tubes were fired, the target presented 160° port angle on the bow which increased to 180°. Knightish indicates that he was turning during the time of firing, and when he thought he had steadied his angle on the bow as apparently varying between 70° and 110° port, all torpedoes missed ahead.

After being driven down by gunfire from the other ship on the starboard bow, two explosions were heard, these sounded like torpedo explosions and may have been hits on a ship that was astern of the main group and not visible from the bridge.

Remark: :

(1) NOTES:

(2) ARTICLES:
No articles were found.

(3) ARTICLES:
After the attack on the twenty sixth we were forced to submerge by accurate gunfire from a ship of the convoy. The first burst of 20mm fire landed about 75 yards off the port bow, and from there on shells were landing all around. After submerging a few depth charges were dropped, none close. Echo-ranging was heard later, but the search seemed to be conducted haphazardly and we were not picked up.

Evasion tactics consisted of going deep and running, silent at the highest speed possible to clear the area.

— page 138 —
1. MAJOR DEFECTS AND DAMAGE (Continued)

The Conning Tower had a large history of leaks, at the present time the leak occurs while submerged, and leaks until the pressure is sufficient to seat it. The hatch dogs have been adjusted numerous times, and it is believed that the seat is not true.

The starboard propeller was badly dent when an uncharted submerged obstruction was hit near the fuel barge at Exmouth Gulf. A new propeller was installed upon return to Fremantle.

The bearing end plate on number 4 main generator allowed oil to leak into the fan housing. The end bell was removed and the plate tightened at sea.

The auxiliary gyro motor generator armature burned out, and was satisfactorily rewound at sea.

The Q/JK training motor generator bearings are extremely noisy. These bearings have been checked during previous refits but are still unsatisfactory. It is believed that either the shaft is bent or the motor generator is out of alignment.

The QE sound shaft appears to go out of line at depths over 100 feet causing the drift stop roller bearings to gouge the roller rings.

The cylinder liner of #9 unit on #4 main engine was found to be cracked, on getting underway from Exmouth Gulf, W. A.

2. DIO

Radio reception was poor in the Manila area due to high noise level and interference from other radio transmitters, 6,150 kcs was very good during daylight hours.

The voice circuit on 2D80 was excellent for both transmitting and receiving, no interference was experienced on this circuit.

All serials were received.

1. The fourth patrol of the "U.S.S. ANCHOR" was conducted in the South China Sea west of the Philippines. For the first eighteen days in the area, the ANCHOR acted as one of three submarines in a coordinated attack row with the U.S.S. FLASHPROOF (SS76) and U.S.S. CHINAMP (SS91).

2. Contact was made on two convoys. The first convoy, which included an escort carrier, was attacked by a U.S. submarine on 25 June and a U.S. submarine on 26 June. The second convoy was attacked by a U.S. submarine on 26 July and a U.S. submarine on 27 July. The attack was successful, and the U.S. submarine was lost.

3. A normal refit will be conducted on the ANCHOR. The submarine will be rearmed and refitted

Via: The Commander, SEVENTH FLEET.

Subject: U.S.S. ANGLER (US240) - Report of Fourth War Patrol - Comment on.

1. ANGLER's Fourth War Patrol was conducted in the SOUTH CHINA SEA in a coordinated attack group with FLASHER and CREVALLIE. It was the first War Patrol for the new Commanding Officer, Lieutenant Commander F. G. HESS, USN., as such.

2. ANGLER made the initial sighting on the convoy which was so destructively attacked by the Coordinated Attack Group on July 25-26. The contact report and two amplifying reports which were sent out prior to diving for the first approach enabled both FLASHER and CREVALLIE to gain contact in about one hour.

3. The large AK which was hit by two torpedoes in Attack No. 1 probably sank. It is regretted that there is not sufficient evidence to substantiate that assessment.

4. This patrol is designated "successful" for the award of the Submarine Combat Insignia.

5. The Force Commander congratulates ANGLER Commanding Officer, Officers, and Crew, on inflicting the following damage on the enemy:

DANGER
1 - AK (ASOSAN MARU Class - EC) - 8,800 Tons (Attack No. 1)

26 September 1944

At Darwin, Australia awaiting arrival of officer replacement. During the day made an automobile trip to RALF headquarters for North Western Australia to discuss the current operations and pick up any late intelligence information on the operating areas.

The visit was very interesting and the RALF and R.N. officers contacted were very cooperative.

In connection with the stops at both Exmouth Gulf and Darwin, I cannot praise too highly the splendid work being done by Lieutenant J. T. Wolford, Jr., U.S.N.R. at Exmouth Gulf and Lieutenant D. H. Ebyrly, U.S.N.R., commanding U.S.S. COUC.L. Both of those officers work with meager resources, but are willing to do all in their power to effect repairs or provide materials required by the submarines.

— page 152 —
11 October 1944 (continued)
0646 The tanker and escort disappeared in the channel. Scoured from battle stations, and decided to remain in the vicinity until they came out, started patrolling 3 miles off entrance. 0734 Sighted two small sea trucks proceeding south. Sea is flat calm without a ripple to be seen. 1206 Sighted plane through periscope over Puerto Princiosa, low wing, single engine monoplane. 1532 Sighted plane in approximately same position as (a/0#12) It appeared to be taking off. 1602 Sighted high wing, single engine, monoplane over Puerto Princiosa. 1620 Sighted low wing monoplane over Puerto Princiosa. 1638 Same as above.

Escort is well clear to south. 0736 Target is changing course to south and speeding up, started swinging for bow shot, but it looks like we are on a limb. 0745 Target has settled on course 220° T speed 12 knots. We are abaft his beam range 3,800 yards, torpedo run 4,600 yards, decided not to fire at extreme range because sea was like a mirror, with not a ripple to be seen. Came to trailing course in hopes he might zig but at 0810 With range 10,000 yards gave up chase. The target and escort turned sharp after leaving entrance and proceeded south about 2 miles off the coast. 0814 Sighted low wing monoplane similar to Val in the direction of Puerto Princiosa.

14 October 1944 (continued)

0645 The target group now appears to be made up of three heavy ships and two escorts in loose column formation with distance between ships about 1500 - 2000 yards.

The first ship was the smallest, an engine aft freighter with a deck load of lumber estimated tennage, 3,500-tons. A DE type escort, pinging, was located on its port bow.

The next ship was a medium AF of about 7,000 - 8,000 tons, single stack, with 5 or 6 lifeboats to a side, and the numeral 2 painted on his stack.

The third large ship was an AK of about 5,000 tons, stack amidships and heavy masts forward and aft.

0655 The second escort was astern and appeared to be a heavy trawler fitted out as an escort.

Patticks stations. As the ships came closer it became evident that divided fire would be practically impossible because of the distance between targets, but if the set-up changed there might be a chance to get a shot at the second and third targets. Since the AP was the largest of the three ships, decided to make her the primary target.

0720 Set up has not changed appreciably, except for stern escort, who seems to be coming up our side of the convoy, and is drawing ahead.

With a 90 starboard track torpedo run of 1950 yards commenced firing four torpedoes. As periscope was raised for second firing bearing, the escort coming up from astern of the convoy, was passing about 400 yards ahead. Torpedoes one and two were seen to run under him. As the last torpedo was fired this escort had full right rudder on, and he was clawing his way around to get at us. There was much scrambling around on his docks, so ordered 300 feet.

07-35-36 First torpedo explosion.

— page 155 —
1. USS, ANGLER - Report of Fifth War Patrol

Second torpedo explosion. These two explosions timed to a torpedo run of 1932 and 1950 yards respectively for the first two torpedoes fired. The hits were not observed, because the periscope was already under.

First depth charge fairly close and according to the CDDI under, ahead, and to port. We were at 225 feet working into a layer.

Depth charge number two further away ahead, above and to port.

Third and last depth charge, above, astern, and to starboard. We were at 350 feet, making 2/3 speed under a six degrees negative gradient.

Sound heard breaking up noises and the escaping air noises in the direction of the target.

As soon as we were squared away, decided on an escape sector and commenced fish tailing in this sector at 2/3 speed. Both escorts are alternately pinging and stopping to listen. They seem to have a good idea as to where we are from their direction of pinging but never seem to be sure enough to drop charges. They alternate closely the range pinging, then open when they stop to listen. As soon as we try to get a little water out of the boat either with the trim pump or by blowing, they immediately start closing.

Started up to periscope depth, eventually got to 150 feet, but escorts were closing all during the time we were coming up. With echo ranging, distant astern, came to periscope depth, nothing in sight. Reloaded and resumed normal operation. Target group was proceeding up Tablas Straits.

The approach and evasive action while successful were slightly hampered by having to use No. 1 periscope, because No. 2 gives a double image and alternately fogs and clears. Number three main motor is noticeably noisy when operating silent, probably due to the commutator being rough, a cut was taken on the commutator last raft.

Surfaced, set course to transit hindoro Straits in accordance with Operation Order.

Exchanged recognition signals with U.S.S. BLUEBELL headed north.

19 October 1944

Patrolling line north of Cabra Island.
0230 Received intercept report of BLUEGILL's convoy attack. I don't know how we missed it on 2880 kos. yesterday morning unless we had already submerged. It looks like the area will warm up at least.

0735 Same type of plane as (a/c#36), in same locality.

1215 Sound reported echo-ranging bearing 185° T.

(s/c#15) Started closing.

1253 Sighted SC type patrol boat, conducting a/s search, commenced avoiding, closest range 4,000 yards.

1342 Sighted low wing, single engine, land type plane bearing 193° T apparently searching with SC.

1405 Echo-ranging died out astern in the direction of Cabra Island.

1524 Sighted transport plane landing on north-ern end of Lubang Island. There must be another field not marked on the chart. While we have been in this vicinity we have had a strong radar signal on 105 mcs., and the radar is probably near the air field. Ever since we have been in the Manila area we have had a strong signal on 95 mcs., and it has harmonics, which appear as we approach the coast.

1555 Sighted a Betty type plane taking off the field on Lubang Island.

1848 Surfaced, with the BLUEBILL gone, decided to run a surface patrol off north end of Palawan Passage this seems to be a better way to cover the southwest approaches to Manila, rather than try to cover either one of the two passages submerged. Set course for north end of Palawan Passage.

22 October 1944

0145 All hands on the bridge practically turned in their suits, when suddenly out of a pitch black night a voice started shouting "Help" or its equivalent, nothing in sight, nothing on the radar.

— page 159 —
22 October 1944

0145 Started searching to locate man in the
con- water. We could hear him shouting but couldn't
locate him. We thought we had him a couple
of times and threw the line ring, but looking
back I think we were tossing it at dead Japs.
0320 Rader reported what appeared to be a pip at
31,000 yards, put on four engines and headed
toward on true bearing.
0400 Radar hasn't had pip since 0325, so con-
cluded it must have been a rain squall.
Reversed course so had back toward the voice.
0520 Passed lifeboat with several people waving,
decided to look for voice and then come back
to lifeboat.
As day continued to get brighter the pic-
ture developed into one of the most gruesome
sights imaginable as far as you could see,
the water was covered with bits of wreckage
and dead Japs (Japs well located and look
3 to 4 day's old), all bodies seemed to be
in Jap Army uniforms.
0552 High periscope sighted masts bearing 150° T,
range 15 miles. Closed range and made out
what looked to be about a medium A0 and one
escort, horizon was hazy. Stationed the
tracking party and commenced tracking.
C710 Targets track on course 3560 T speed 8 knots.
C/17 On targets track range about 30,000 yards,
so submerged.
0730 Battle stations submerged.
0743 Masts in sight, position good, but masts of
both ships appear to be the same.
0755 Sound reported two sets of light screws,
160 rpms, for 8 knots? Intermittent echo-
ranging.
0827 Range 4,000 yards our A0 and escort iden-
tified as two trawler type patrol craft,
the same as the ones encountered off Lubang
Island. Too small for torpedoes and
apparently looking for trouble, so took up
"normal escape course." Both mounted what
appeared to be a 3-inch gun in the bow.
1030 Passed through a practically a continuous
to stream of wreckage and dead Japs.
1400
1433 Surfaced.
1445 SD radar contact 36 miles. This contact
(a/c/41) was on the screen from this time until 1630,
at ranges varying from 26-36 miles.

— page 160 —
22 October 1944 (continued)

1446 Passed came lifeboat as we had seen in the morning, decided, with plane on the radar to come back and investigate about sunset.

1805 Brought lifeboat alongside, counted 26 men in the boat all are soldiers and Jap naval raiding and appear very young, three of the soldiers didn't look more than 14 years old, no evidence of dying for the Emperor in this outfit, one of them was over the side and aboard before the lifeboat got alongside, and they all started aboard as soon as the lifeboat hit the side. After cutting them all back in the boat, we found out who as in charge and let him come aboard. A second lieutenant in the Army. He could speak some English, so asked him if there was anyone who could speak more English than he, and immediately hit the dock.

We asked them if they wanted to go with us, and they immediately agreed, and wanted to bring one more buddy along so made: Second Lieutenant Seigi Shimazu; Sergeant Sei Fuji, and Sergeant Toyonaga Nishikawa prisoners of war.

I think these three will be very valuable to the Intelligence section. All hands were warned on not asking them questions, but all three speak, read, and write English, and understand it when spoken slowly; and are voluble in their conversation.

All three are young and two were Imperial University students. There is certainly no Banzai spirit among the three, and they wanted to know how soon we were going to win the war.

The lifeboat looked sort of unseaworthy and from the equipment on board didn't look like it would make land, so gave them some water, food and course to land, 80 miles away.

Everyone seemed satisfied so had the Pharmacist's Mate inspect prisoners, give them a bath and put them under guard in the Forward Torpedo Room. All are in good shape after four days in the lifeboat. Apparently the RATON is responsible for today's wreckage.

— page 161 —
22 October 1944 (continued)

The second lieutenant seemed well prepared for a good leave with about 2000 pesos and two condoms in his wallet.
Resumed patrolling at north end of Palawan in hopes DARTER's three BB's might come by.
Started patrolling along traffic route to Manila.

23 October 1944

Decoded DARTER's number 6 and headed back for Palawan a full speed, heading for convoys estimated 1800 position.
While watching a plane on the SD closing from 28 miles, another pip appeared at 16 miles closing rapidly, so submerged.
Heard six very distant heavy explosions. They sounded more like gunfire or bombs than depth charges.
Sighted single float, Pete, biplane, range 4 miles.
Sighted masts of six ships bearing 0670 T, sound reported intermittent pinging.
Closed the range and saw they were all trawler or sea truck size, on course 150° T, speed about 10 knots. Since we are within 20 miles of the DARTER since we are with position, and chasing sea trucks offers little return, decided to remain submerged and undetected until about 1530.
Sighted Pete type plane on a/s patrol.

Surfaced. Started a battery charge, so we would be all set by dark.
Commenced patrolling across Task Force route, SJ radar contact 31,000 yards bearing 330° T.
Put 4 engines on the line, aux. generator on the battery. All ahead flank, and headed in.
Range 21,000 yards true bearing 003° T.
Radar had two very large pips, two more slightly smaller and six smaller pips. We are losing true bearing and are abaft his beam, so came to parallel course to try to gain bearing.
From the bridge two large objects and two somewhat smaller can be seen at 20,000 yards.
APR reported strong radar signal 150 ms. sweeping. This signal steadied on us and became very strong then faded out and was not picked up again. SD sweep indicated no plane.

-16-

— page 162 —
23 October 1944 (continued)

2000 Tried to raise BREAM AND GUITARRO on area frequency, no luck.
2030 Task Force on base course 050° T, zig-zagging 30° each side of base course. Sent contact report to CTF 71. VHM answered promptly and report was cleared with minimum delay.
2038 Noted weak SJ radar interference on port quarter which quickly faded.
2200 True bearing now 3500 T. We are not doing too well, 18,7 knots into the sea.
(s/c#19) SJ radar contact showed six good 1100 T. This contact showed six good sized pips plus several smaller ones. Shifted TDC to this group. It tracked on course 170° T, speed 9 knots, which headed convoy for Linapacan Straits, 40 miles to shoal water.
It was a great temptation to drop the Task Force, and grab this plun, but there seemed to be little question as to which way the cards were turned.
In the process of getting around the convoy, we ended up astern range 20,000 yards, so decided to trail on the quarter in hopes someone would turn them.
At this point Task Force is headed for Calvito Passage, so decided not to send another contact report until a definite trend away from this point is noted.
2230 Picked up weak SJ radar interference bearing approximately 062° T.

24 October 1944

0100 Task Force has shown a definite trend to the right, base course for the last hour 0900 T. Prepared second report, just as we finished calling, with no answer, decoded GUITARRO's report giving essentially the same information so secured trying to send my message.
Task Force has straightened out and now seems to make only occasional zigs. It looks like they got a probable contact occasionally and make a 40 or 50 degree turn.
There is an occasional 85 mms. signal on the APR and generally corresponds with one of these zigs. It is a steady signal where it is on.

— page 163 —
24 October 1944 (continued)

0200 Task Force has finally committed himself to Minoru Ostraits. It looks like the avoidance of Balabac has really cost him. His speed has been checking between 19-20 knots the last hour, and ours has increased to 19.5 because of steadily calming seas.

0230 Tried to put contact report on the air and the Japs were on us like a tent. We thought VHM had answered our call so sent report, but as soon as we had finished a Jap station alternately calling himself VHM and NDPL came on, asking what his signal strength was and transmitting continuously. Gavo radionm instructions to send Q signal asking for authentication, and no more. About this time GUITARRO opened up and sent contact report blind. We received no answer to our request for authentication, so decided to wait and see whether our or the GUITARRO's report had gotten through.

0240 Broke off the chase and decided with a little crystal ball work that the GUITARRO would probably go back to Calavite and patrol so our best bot was to patrol north entrance of West Apo Pass in case Task Force doubled back.

0340 We were just getting set up to try to get our report through again when GUITARRO's report came back on the Baster schedule, so scoured.

0450 Submerged.

0540 Heard loud explosion quite distant.

0548 Sighted Betty type bomber circling in the direction of Cape Calavite.

1839 Surfaced, started back toward Cape Calavite.

1845 Picked up weak SJ radar interforonce dead ahead. I guess we were correct in assuming GUITARRO would head for Calavite.

2030 Received VCT 71 Serial number 24 getting our patrol station squared away.

25 October 1944

Patrolling across Calavite Passage

0438 Submerged in Calavite Passage, patrolling back and forth across Passage.

— page 165 —
25 October 1944 (continued)

0651 Sighted Betty type bomber range 8,000 yards, (a/c#47) angle on the bow zero.
0928 Sighted Dave type plane patrolling range (a/c#48) 3 miles.
1300 JP sound gear reported screws and Periscope (s/c#20) Watch sighted Fubuki type destroyer range 10,000 yards angle on the bow 60" starboard. Went to Battle Stations, and made ready the tubes. Came to normal approach course trying to close but target went by at 4,600 yards, speed 20 knots. After clearing Cape Calavite target turned to course 150° T and disappeared heading for Mindoro Straits.
1900 Surfaced, half moon is very bright, so decided to patrol in and out along moon streak 10-15 miles of Cape Calavite, zigzagging.
1944 SJ radar contact bearing 162.5° T, range (s/c#21) 30,000 yards, commenced closing and tracking.
2015 We now have two pips on the radar, but there is something wrong here someplace, as the range closes the pips got weaker. Targets tracking on course 0100 T, speed 16 knots. We cannot get ahead of them before they get to the Passage, and cannot make a flank attack because of the moon.
2200 We have closed the range to 14,000 yards, and still cannot see the target, and the one remaining pip is very weak, course now 060° T, speed 16 knots. Secured tracking and after reviewing the proceedings thought perhaps we had been drawn off of possible targets heading west by this apparent phantom heading north. Started a swoop to southwest at full speed.

26 October 1944

0039 SJ radar contact bearing 148° T, range (s/c#22) 25,000 yards. Started closing and tracking at flank speed. Two pips on the screen. This group tracked on course 280° T at the start and gradually worked their way around to 0000 T, speed 20 knots.

— page 166 —
26 October 1944 (continued)

0106 We are on target's starboard beam range 16,000 yards. Aoting as an escort more or less radar pips are not very strong and nothing is in sight from the bridge. 0128 ST radar reported a large pip in direction of target's range 5,000 yards, the range opened rapidly to 14,000 yards and pip disappeared. It must have been a plane, no signals on the ATR. 0144 One of the targets needed out our way and range begun to close readily, so turned away and started tracking. 0155 Target resumed his base course. 0244 Targets course now 0600 T, steering Galvite Passage. Secured tracking and resumed patrol. 0340 SJ radar contact bearing 1500 T, range 21,000 yards. Started tracking what appeared to be three pips very weak fading in and out. 0355 Targets track on course 1600 T, speed 12 knots, heading down coast of Mindoro. We are astern and cannot overtake them before daylight, so it looks like we will have to let our best prospect of the night go by. SJ radar contact bearing 3120 T, range 19,000 yards. There is also strong SJ interference on this bearing, probably from the GUITARRO. 0444 Submerged 3 miles off Cape Calavite on the track of last night's activity. In looking back I think all of the night's contacts were on destroyers with the possible exception of #23 and from the size and character of the radar pips, it is believed this may have been a convoy of 3 or 4 small or medium ships. 0651 Sighted a "Rufe" type plane bearing 0420 T, range 4 miles apparently patrolling. 1055 Sighted a "Rufe" type plane bearing 1100 T, range 5 miles, patrolling. 1311 Sighted a "Pete" type plane bearing 1710 T, range 3 miles, patrolling. 1537 Sighted a "Pete" type plane bearing 0760 T, range 4 miles, patrolling. 1653 Sighted a "Rufe" type plane bearing 2800 T, range 8,000 yards, patrolling.

— page 167 —
26 October 1944 (continued)

1714: Sighted a "Pete" type plane bearing 2750 T, range 6,000 yards.
1725: Sighted the mast of a possible destroyer range 20,000 yards, estimated course 0000 T, speed 20 knots.
1743: Mast of target has disappeared.
1904: Surfaced.
1908: SJ radar picked up a plane range 6,000 yards bearing 0670 T. The bearing dropped aft rapidly, a minimum range of 3,000 yards was reached then the range opened to 13,000 and plane disappeared.
Manned the "SDM" radar keying it for 5 seconds out of every 30 seconds. The moon is very bright.
1908: SJ radar contact bearing 0200 T, range 21,000. There is strong SJ radar interference on this bearing. Closed the contact and exchanged recognition signals with the U.S.S. GUITARRO. The GUITARRO was picked up by sight at 13,000 yards.
2020: SJ radar reported one plane at 12 miles.
2050: "SD" radar reported two planes at 10 miles.
2051: "SJ" radar picked up two planes, one on the port beam and one astern. The plane astern started closing with a steady bearing.
2055: Submerged, range to plane astern 7,000 yards.
2130: Radar depth, planes still around.
2205: Radar depth, all clear, surfaced.
2238: "SD" radar picked up plane at 14 miles, range closed to 10 miles, then opened out and disappeared.

27 October 1944

0444: Submerged, 4 miles off Cape Calavite.
0632: Sighted a "Pete" type plane bearing 0530 T, range 5 miles.
0634: Sighted two trawlers proceeding along the coast going south.
0702: Sighted a plane bearing 0970 T, range 4 miles.
0755: Sighted a plane bearing 1080 T, range 3 miles.
(a/c#63):

— page 168 —
27 October 1944 (continued)

0813 Sighted a plane bearing 300° T, range (a/c#64) 4 miles.
0923 "JP" sound gear picked up and periscope sighted masts of a destroyer bearing 0760 T, range 12,000 yards. Went to Battle Stations, came to normal approach course.
0935 Three Fubuki type destroyers in sight on line of bearing, speed 18 knots.
Minimum range reached 6,000 yards.
Targets rounded Cape Calvaite and headed south.
1020 Sighted a Pete type plane bearing 125° T, range 3 miles.
(a/c#65) 1055 Sighted a "Pete" type plane bearing 300° T, range 5 miles.
1112 Sighted two destroyers in line abreast bearing 1450 T, range 10,000 yards, angle on the bow 900 port, started closing. These may have been two of the three destroyers, that headed out this morning, returning.
1405 "JP" sound watch reported screws bearing 1280 T, could not see anything through the periscope. The bearing was dropping aft slowly.
(a/c#30) Our best soundman reported the screws sounded like a submerged submarine, with the characteristic motor hum present. I am convinced, put the screws astern and started opening out. He is between us and Cape Calvaite.
1520 Stopped our own screws and listened very carefully, but could not pick up our friend.
1619 Sighted a "Rufe" type plane bearing 0500 T, range 6 miles.
(a/c#67) 1902 Surfaced.
1931 SJ Radar contact bearing 123° T. Two pips one at 23,000 yards one at 31,000 yards. Both are in the general direction of Cape Calvaite.
(a/c#68) At the same time "SD" reported a plane, range 14 miles.
1946 Started tracking and closing.
1946 SJ radar reported plane contact at 14,000 yards.
The bearing of this plane dropped aft with the same range until it was dead astern, then started closing.

— page 169 —
27 October 1944 (continued)

1954: Submerged. Range to plane 10,000 yards closing from astern.
2040: Surfaced. No targets on the SJ so assumed group had gone into Calavite Passage, from our meager information they were headed that way at high speed.
2115: SJ radar contact bearing 335° T range 16,000 yards. started tracking. At 14,000 yards target could be clearly seen from the bridge and appeared to be a "PC" type patrol boat. Speed 18 knots, course 0000 T, decided to keep clear.

28 October 1944

Opening the coast to send our number 5. I hope we can get it off all antennas were found to have zero grounds, and we will try the SD tonight.
0030: Completed sending Anglor #5. As long as we can use the SD antenna, I don't think we can afford to take the time out to try to clear the other antennas.
    Decided in view of a possible Jap submarine at Calavite to shift our station south to see where the Japs are coming from, picked what looked to be a focal point about 17 miles off the coast.
0437: SJ radar contact, two pips, range 15,000 yards, bearing 0900 T.
    At the same time the APR watch reported very strong signals on 178 mcs, from two sources, sweeping across us then steadying on.
0447: Twilight is only 10 minutes away so placed contacts astern. The range is closing and APR signals getting stronger.
    Submerged, range 13,000 yards.
    As soon as we were down sound reported two sets of light screws astern. Opdaced 250 feet and changed course to south.
    The two apparently radar equipped patrol ships, slowed and listened and maneuvered around until,
0600: then speeded up and headed north. I think they probably had some sort of radar contact with us before we dove, but didn't pick up sound contact.

— page 170 —
28 October 1944 (continued)

0640 Sighted a single engine low wing monoplane bearing 330° E, range 6 miles headed for us.
0735 Sighted a "Rufe" type seaplane, patrol-lining.
1850 Surfaced, started patrolling along routes from Marilla to north er erance to Palawan.
2330 Exchanged calls with U.S.S. NAUTILUS headed south.

29 October 1944

Patrolling north entrance to Palawan Passage.

30 October 1944

Patrolling north entrance to Palawan Passage.

31 October 1944

0445 Submerged, patrolling entrance to east Apo Passage, proceeding into Mindoro Straits.
0555 Sighted two ships and one escort bear-ing 2000 T, range 13,000 yards. Went to Battle Stations and started approach.
0620 Targets identified as two small AK's about 2000-2500 tons, one with stock a't, one with stock amidships. The escort is a small SC. They look small but we are on our way home.
0630 Targets have zigged to course 100° T.
0638 Made ready the tubes.
0640 The targets have come back and we are in position for a stern shot.
0646 With 100 port track range 2100 yards commenced firing four stern tubes.
0648 Target started blowing whistle and turning to put his stern toward us. No hits. It is believed that at least one of the torpedoes ran under the target, but did not hit because of shallow draft. Torpedoes were set at 6 feet.
0653 The escort is coming down on us with zero angle on the bow, so went deep, rigged for depth charge and silent running. The escort is not echo-ranging but seems to stop and listen then ease in a ways.

— page 171 —
21 October 1944 (continued)

0705 Two depth charges not too close, according to the Depth Charges Indicator, above, aft, and to port.
0722 Made a torpedo reload aft. Screws faded out astern.
0835 Periscope depth, all clear.
1845 Surfaced, continued south through Mindoro Straits.
1930 Sent Angler 6 to set rendezvous with U.S.S. HARDEAD.
2100 Departed area.
2230 Exchanged calls with the U.S.S. RAY headed north.

1 November 1944

0216 Exchanged calls with the U.S.S. HAKE, headed north.
0250 Contacted U.S.S. HARDHEAD, dead ahead.
0325 U.S.S. HARDHEAD alongside to port.
Commander Fred E. BAKUTIS, U. S. Navy came aboard. Commander BAKUTIS was resumed by U.S.S. HARDHEAD, and is aboard for transportation to Fremantle.
0735 SD radar contacted two planes, neither of which showed IFF response. One of the planes was sighted and identified as a Liberator. The other was not sighted and the range was closing at 10 miles, so at 0742 Submerged.
0819 All clear on the CD radar, surfaced.
1100 Sighted small schooner, it appeared to be a native craft, so did not bother it.
(s/e#35) During the afternoon sighted several small sailboats.
1133 "SD" radar contact 22 miles, range closed to 20 miles then opened and disappeared.
(a/e#73) Passed Doc Can Island abeam to port, range 5 miles.

2 November 1944

0112 "SD" radar contact 12 miles, closing, exchanged signals on IFF. SD radar picked up plane at seven miles on the starboard beam, bearing dropping aft. Sighted and identified plane as a "PBM". Plane passed astern and range opened rapidly.

-25-

— page 172 —
2 November 1944 (continued)

0240 Sighted two very small boats, range 4,000 yards bearing 180° T. These two boats seemed to move about quite rapidly but made no attempt to close and the maximum range at which the SJ could pick them up was 4,200 yards.

Continued course and speed, and the two boats dropped aft rapidly.

0245 Commenced transit of Sibu Passage.

0351 Completed transit.

0855 After dodging several whales, one made a submerged approach and was hit him, possibly with the screws. There was much blood and dead whale scuttled around aft. There seems to be no damage to the screws.

1144 Exchanged calls with the U.S.S. GUNNEL, headed north.

1200 Sighted unidentified U.S. submarine, bearing 160° T, range 7 miles, headed north.

3 November 1944

Enroute through Macassar Straits.

0532 Made trim dive.

0612 Surfaced.

0812 SD radar contact 18 miles. Contact closed to 16 miles then opened and disappeared.

0830 Sighted unidentified U.S. submarine, bearing 115° T, range 10,000 yards, headed north.

0940 SD radar contact, 18 miles. Contact disappeared at 22 miles.

1230 Cape William abeam to port, distant 19 miles.

1350 Sighted two floating mines in Latitude 30-00' S Longitude 117-55 E. Both appeared to be moored mines which had broken loose. They were covered with rust and barnacles.

The driftwood and various bits of floating debris gather in definite areas in Macassar Straits and the two mines were in one of these areas.

Numerous sailboats and unidentified objects were seen during the afternoon.

   15 miles.
1846 Surfaced, set course for Lombok Straits.
2155 APK picked up radar signal on 220 mcs.
2238 Sighted two objects on the horizon which
   (s/c#37) appeared to be patrol boats, avoided.

5 November 1944

0027 Commenced transit of Lombok Straits.
0133 SJ radar contacted two patrol boats bearing 170° T and 190° T ranges 9,000 and
  10,000 yards respectively. Started
   avoiding.
0215 We have gradually worked our way around
   both boats but in so doing we are skirting
   the coast of Nusa Besar about 3 miles
   offshore.
   There is a radar station believed to be
   on southwest tip of Lombok Island on
   198 mcs. This signal has grown stronger
   as we have come south, and has been trained
   on us quite steadily.
0305 Completed passage of Lombok Straits. Set
   course to conform with safety lanes.

November 6-9 1944

Enroute Fremantle, Western Australia.

November 9 1944

1000 Arrived Fremantle, Western Australia.
   Ran degaussing range and conducted surface
   sound test.

U.S.S. ANGLER - Report of Fifth War Patrol

(C) WEATHER
The weather in the Mindanao Sea from 5 to 7 October was almost constantly squally with strong winds from the Southwest; otherwise no unusual weather conditions were noted.

(D) An C.3 knot southerly current was noted in Mactasser Straits. Southern approaches. A 2.5 knot southerly current was noted during passage through Mactasser Straits. A 4.0 knot current setting 202° T was noted in passage between Pearl Bank and Doc Can Islands. A 1.8 knot current setting 130° T was noted throughout the night 20 to 30 miles north of and parallel to the Sulu Archipelago. A constant 1 to 1.5 knot southerly current was found to exist off the coast of Palawan, P. I. near Puerto Princessa.

(E) For night radar navigation off Puerto Princessa, Palawan, P. I. it was found that the left tangent of the harbor entrance was about the only distinguishable land mark. No navigation lights were noted burning.

1. ATTACK DATA
Time: 0734(H)
Description:
TARGET DATA - DAMAGE INFLICTED
Exact identity of the target was uncertain, but it was a medium sized transport, resembling, somewhat, the Montyvideo Maru, page 50, ONI 208J revised. This ship was second ship in column of a convoy composed of three ships and two escorts. An AK similar to Takason Maru, page 267, ONI 208J revised was the leading ship and an AK similar to the Daiti Maru, page 193, ONI 208J revised was the third ship. A DE type escort was on the port bow of the leading ship and a trawler type escort was astern. Contact was made by sound on the pinging of the DE, visibility was very good.

Ship's Sunk: None

Ship's damaged: One (1) Medium AP (EU) 7,500 tons. Probably sunk.

Damage determined by:
Two timed torpedo explosions which matched within 75 yards the torpedo run set in the TDC. Breaking up noises heard on sound gear for a period of one hour after the attack.

Target Draft: 25' Course: 038° T Speed: 9.5 Range: 2,000(at firing)

OWN SHIP DATA
Speed: 3 Course: 315 Depth: 65° Angle: 60°

PIRE CONTROL AND TORPEDO DATA
Type Attack: Normal day submerged, periscope attack.

TARGET DATA - DAMAGE INFILTED

Description: The target group was composed of two small coastal AK's and one SC escort. They were in loose column, escort leading. The last ship in column was chosen as target. The targets were zigzagging radially, one zig of 105° was noted during the approach.

Ship's Sunk: None

1. MINE
No mine laying operations were noted.
Two floating mines were sighted in
Latitude 30 - 00' South Longitude 117° - 55'
East. Both mines were very rusty and covered with barnacles. They looked like
moored mines which had broken loose. They
were round and had what appeared to be
horns on them.
Both mines were in a drift stream with
other debris, (floating logs, coconuts, etc.)

(J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS

The only anti-submarine measures not
encountered on other patrols, were the
night flying aircraft. On the night of 26
October, the first plane contacted passed
the ship at 3,000 yards, bright moonlight,
without apparently sighting us, but later
on two planes came back, one believed to
be radar equipped, 85 mes, and took station
on us, one astern and one on the port beam.
The plane astern then started closing
rapidly, so we submerged, no bombs were
dropped. On 27 October the single plane
contacted also took position astern and
started in for a run.
Air coverage of the Manila area was very
heavy during the day, and the night patrols
seemed to operate only in bright moonlight,
and not after midnight.
The escorts and patrols encountered
scorched in the normal manner echo ranging
and listening.
Evasion tactics consisted of going deep,
picking out an escape sector and fish-
tailing in that sector at two thirds speed.
In evading, whether deep or at periscope
depth, every effort is made to maintain a
constant noise level, in other words if we
are at periscope depth with normal aux-
illaries running and a patrol vessel is
within listening range scans to become
suspicious, we maintain the same speed and
same noise level in the ship. This has
proved successful during this patrol where
a number of patrol vessels were encountered.

1. U.S.S. ANGLER - Report of Fifth War Patrol

Major Defects and Damage

The outstanding major defect reported before and still uncorrected is the Gardner-Denver type trim pump.

The other defects noted during the patrol were as follows:

(1) The Kleinschmidt stills both apparently have pin point holes in the coils, and until scale forms on the tubes about one-third of the water manufactured is too salty for use.

Both stills have salt water leaks around the heaters and the port tub oil jacket leaks.

Port compressor does not operate properly because of faulty bearings.

(2) The QC/JK training motor generator, reported in poor condition after last patrol, is still unsatisfactory.

(3) The shaft of the JK/QC sound head is out of line, or pitted to such an extent in the packing glands, that it makes a pronounced rumble when being trained.

(RADIO)

Considerable Jap radio interference and jamming was experienced throughout the patrol. The worst case occurred during the transmission of ANGLER's second contact message on a Jap Task Force. VHM had apparently answered our call, so we thought, and we transmitted our report. Immediately following our transmission a Jap answered on a speed key using VHM's call sign and QSA; the speed key did not seem right, and after a period of our silence the Jap again answered using a hand key with the call signs NDP4 and VHM; our request for authentication with QLA brought the Jap response of QSA again, whereupon we secured. This message was not received for nor was it repeated on the Baker schedule a further check showed that all three of our antenna registered zero ground. Four day's later from the same general area, off Cape Calavite we sent another message using SD antenna; VHM did not receipt for this message, but it later came back on the Baker schedule.

CW - Random Keying and MCW proved to be the two most frequent types of jamming used by the Nips. For more complete information on type of jamming and localities see the report forms "Radio Communications - Interception and Jamming by the Enemy."

The performance of all radio transmitters and receivers was satisfactory; the zero ground developed in each of our three long ships' antenna was the major casualty.

Our new Telikback system installed during the last refit contained a number of faulty parts and proved troublesome throughout the patrol.

All serials were received.

(M) RADAR

The performance of both the SJ-A and SD radars was excellent throughout the patrol. All breakdowns were minor and quickly repaired.

The APR-1 installed during the last refit was used extensively in the area and was very satisfactory. The output of this instrument was hooked up to an oscilloscope in order to give the operator a visual as well as audio indication of enemy radar. The results obtained in using this equipment are tabulated in section "U".

(N) SOUND GEAR AND SOUND CONDITIONS

Sound conditions in the western Mindanao Sea area permitted listening ranges up to 9,000 yards. The JX picked up a scamp at 9,000 yards, and the JP picked up the same scamp at 6,000 yards. Fish noises proved somewhat troublesome in this area.

In the western Sulu Sea area off Puerto Princesa sound conditions proved to be exceptionally good. Both the JK and JF picked up the screws of a tonker at 14,000 yards.

The Cape Caliurite area had normal sound conditions 7,000 yards over the period of the ANGLER's stay. All sound gear was used during day's submerged; the JP usually picking up the target before the other sound gear by approximately 4,000 yards.

General Comment:

The performance of duty by all hands was excellent and left nothing to be desired. During the two attacks made and the time spent off Manila where we were under practically constant observation by the enemy all hands performed their duties in a normal manner and showed no evidence of strain. In connection with training while proceeding to the area, it is felt that two boats working on each other is the best setup. More than two boats tends to get complicated and the speed of advance is difficult to maintain.

(V) REMARKS
No enemy minesweeping activity was noted. All traffic coming out of Calavite Passage headed south for Mindoro Straits staying close to the coast. No traffic was noted coming out of Calavite Passage and heading west. One convoy was contacted 70 miles north of Linapacan Straits heading for the Straits. The Mark II I6d 2 Emergency Identification Signals proved of no aid in establishing our identity. Three green signals were fired during torpedo approach in the training area, no smoke sighted. Five red signals were fired trying to establish our identity to a friendly submarine, none of which functioned.

FIRST ENDORSEMENT to
U.S.S. ANGLER (SS240)
Report of Fifth War
Patrol.

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

Subject: U.S.S. ANGLER (SS240), Report of War Patrol Number Five.

1. This fifth patrol of the U.S.S. ANGLER was conducted in the central and southern Philippines and was marked by intensive air coverage, (7% contacts) and relatively far surface contacts. Two torpedo attacks were made.

Attack No. 1 on 14 October was made on an unidentified transport in convoy with two other ships. A day periscope attack was made from 2000 yards range, resulting in two timed hits, the ANGLER being forced down by escorts before she could watch results. Breaking up noises indicated that the ship probably sank.

Attack No. 2 on 31 October was also a day periscope attack on the second of two small coastal freighters in convoy. The control set up was good. The torpedoes were spread to insure 17% coverage of target length. However all torpedoes missed.

2. In addition to the damage inflicted on the enemy, the highlight of the patrol was the tracking of a large task force on convoy to the Second Battle of the Philippines Sea. The task force was picked up by radar at 1915, 23 October at 31,000 yards and he was tracked until 0240 the following morning. The contact reports sent by the ANGLER were of inestimable value to our forces in that sea battle off Leyte. Ironically the ANGLER contacted the only large convoy of the patrol while tracking the task force but wisely decided to hang on to the task force rather than attack the convoy, although the manouvers to clear the convoy placed the ANGLER ten miles astern of the task force.

3. Three prisoners of war were picked up from a loaded lifeboat, a second lieutenant and two scrogants, whose ship along with three others had been sunk three days previously.

4. Of special interest is the action of enemy radio stations during the tracking of the task force on the night of 23 - 24 October in receiving for ANGLER's messages, asking her to make V's, etc. The report of radio interception and jamming by the enemy is very complete.

Date: 12/04/1944
To: Commander Submarines, SEVENTH FLEET
Via: Commander, SEVENTH FLEET
Subject: Report of Fifth War Patrol

1. ANGLER's Fifth War Patrol was conducted in the KINDAKA and SULU BAY area and was ordered to form a Coordinated Search and Attack Group under the direction of BLUGILL's Commanding Officer.

2. ANGLER made two torpedo attacks, the first of which was successful, resulting in the sinking of a medium AK.

3. At 1915, October 23, ANGLER contacted the Task Force attacked and reported by DARTIE early that morning and last seen at dawn. ANGLER was not able to reach an attack position, but traced the convoy until 0240 the next morning when it was seen to enter HILIBUO STRAIT. Two valuable contact reports were made during this period.

4. From the time that the first enemy heavy units were detected and reported by DARTIE until the end of the Second Battle of the CHILIPINE SEA a marked intensification in Radio Countermeasures by the Japanese was noted. ANGLER experienced difficulty in getting off her second contact report due to heavy enemy jamming and spurious transmissions. Observance of the following will assist in combating these countermeasures:

   (a) Be prepared to shift to the secondary frequency.

   (b) Be prepared to respond to requests for authentication within thirty seconds.

   (c) Regard all speed key or hand sending transmissions with suspicion. All transmissions made by VIX are automatically keyed.

1. TIDAL INFORMATION (con-)
*Several days patrolling the center of Palawan Passage proved a rather consistent southwesterly set of .5 knot, wind and seas from the NE. On one occasion, while ten miles east of Bombay Shoal, wind had shifted from NE to NW, and a northeasterly set of .5 knot was experienced.
During several passages across the northern half of Dangerous Ground (north of 9°) the sets encountered were all in a general northerly direction, from 1 to 2 knots. Wind and seas were moderate and from the NE quadrant. Traveling from half Moon Shoal to Bombay Shoal, a marked change in the set was experienced, the direction of current shifting from north to southwest.

(E) NAVIGATIONAL AIDS
At the southern end of Karimata Strait, Discovery Reef was sighted, marked by breakers and black rocks. On discovery Reef, the ship appeared to be a fishing boat aground.
The following reefs in Dangerous Ground were each sighted one or more times, in daylight during average weather conditions. All, except the eastern side of Union Bank and the eastern end of Tizard Bank, were easily distinguishable from several miles (7 to 9) by the heavy surf breaking over them. During conditions of poor visibility they would be difficult to approach safely:
- Jackson Atoll - Several conspicuous rocks around periphery.
- Hopp's Reef
- Livock Reef
- Union Bank (eastern side) - Whitsun Rf. to Johnson Rf.
- Alici - Annie Rf. - Prominent black rocks all around.
- 1st U. onms Shoal
- Half Joon Shoal
- Hardt's Reef
- Sabik Shoal
- Northcast Investigator Shoal
- Royal Captain Shoal - Large black rocks on southern end very conspicuous.
- Bombay Shoal - Wreck of USS DAFTER visible for several miles.
- West York - Trees conspicuous, especially large clump in center.
- Nanshen Island - Low, with palm trees.
- Itu Ata Island - Buildings and towers very prominent.
- San Cay (Tizard Bank) - Trees visible.

29 of December in position 3-20N 108-36E five floating mines were sighted and destroyed by 20MM fire. On 23 January in position 18-06N 111-06E a single floating mine was sighted and sunk by 20MM fire. All mines sighted were spherical contact type.

(J) ANTI-SUBMARINE MEASURES AND EVASIVE TACTICS

No new anti-submarine measures were observed. On December 24, 1944 while transitting Lombok Strait a small patrol boat sighted this vessel and gave chase opening fire with small deck gun. Evasive tactics consisted of using 18 knot speed vs his 12 knot speed.

(K) MAJOR DEFECTS & DAMAGE - INFLU AND MACHINERY

(1) Six times during the patrol between December 7 - January 3 the south rotor of the master gyro compass had to be pumped down. On the morning of 17 January 1945, the gyro began to vibrate, giving indications of a burned-out bearing. The gyro was secured and the south rotor dismantled. It was found that the lubricating oil had broken down and the lower bearing burned out. The following parts were renewed:

| Part | Description | Quantity |
|------|||
| 1    | Gasket, valve plug retainer | 1        |
| 1    | Gasket, and cap, spring side | 1        |
| 1    | Gasket, end cap, locked side | 1        |
| 1    | Gasket, case cover | 1        |

| 2    | Oil Wilks | 2        |
| 2    | Gyro rotor bearings | 2        |

After assembly a pressure was pumped into the casing and the casing was immersed in hot water to test for leaks. After a satisfactory test the casing was evacuated to 28 inches, the gyro reassembled and started. After a short period of operation, the vacuum dropped to 26 inches where it remained until moving into higher latitudes where it gradually increased. After moving back to lower latitudes, however, the vacuum again dropped to 26 inches.

(K) MAJOR DEFECTS & DAMAGE - HULL AND MACHINERY (con-)

On the morning of 5 February 1945, while steering a constant helm zig-zag, the master gyro was found to have an error of from 15 degrees East to 15 degrees West. The gyro was secured and overhauled on 5 - 6 February by the gyro shop of the U.S.S. FULTON. It was found that the south rotor was unbalanced and vibrating. The following work was done:

Replaced South rotor #363-E with rotor #159-B. Renewed three vertical guide bearings (M.R.C. #36). Cleaned and strained mercury in collector cups and flotation bowl. Cleaned and refilled damping tanks. Cleaned transmitter head and speed corrector mechanism. Since overhaul by U.S.S. FULTON, the gyro has operated satisfactorily.

(2) On 9 December 1944, one coil on the auxiliary gyro motor-generator armature showed an open circuit. This armature has been rewound twice during the past six months. On 21 December motor-generators were traded with the USS ERIGALL. Since this time the auxiliary gyro has operated satisfactorily.

(3) On 17 January 1945, #4 main engine had to be secured because of a drop in lubricating oil pressure. After investigation it was found that the flexible coupling to the attached lubricating oil pump had deteriorated and started leaking. The flexible coupling (EB drawing No. 270261 Items 5,6, and 7) was renewed and no further trouble developed.

(4) On 27 January 1945, some foreign substance entered #1 detached lubricating oil pump causing the liner to be scored deeply in two places. Temporary repairs were made by leading the scored places and then smoothing out. After the temporary repairs the pump operated satisfactorily, but a new casing, or extensive repairs to the present casing, will be required at the next overhaul.

(5) On 7 February 1945, #2 main engine had to be secured because of a broken exhaust valve. The valve had also scored the cylinder head. The complete head assembly on #1 unit of #2 main engine was renewed. At the time of this casualty the engine had been operated for 815 hours since last overhauled. On 9 February 1945, all four exhaust valves on #14 cylinder of #2 main engine were renewed. Although the valve seats on the cylinder head were badly worn, the valves were seated satisfactorily after considerable grinding. The following parts were renewed:

— page 226 —
1. SUBJECT: U.S.S. ANGLER - Report of Sixth War Patrol
- (K) MAJOR DEFECTS & DAMAGE - HULL AND MACHINERY (con-)
- The following parts were renewed:
  - Cylinder head assembly - GM drawing # N-9524"pc. #1
  - 8 Cylinder exhaust valves - GM drawing #N-9629 pc. #21
  - 4 Cylinder exhaust valve springs - GM drawing # N-9629 pc. #27.
- (6) On 8 February 1945, #4 main engine was secured when the operator heard a loud chattering noise. Upon investigation it was found that the pin on the lash adjustment cam of #14 unit had sheared off, freeing the spring and allowing the cam to rotate. This caused play between the cam and the exhaust valve. At the time of this casualty the engine had operated 922 hours since the last overhaul. The following parts were renewed:
  - Bridge, valve assembly - GM drawing # N-9625, pcs. 1,2,3,4,6,7 and 8
- (7) On 9 February 1945, smoke was observed coming from the master gyro control panel. All power to the panel was secured. After investigation it was found that the rectifier tube heater transformer had overheated. This condition was caused by a short in #1 tube socket. Solder from the center contact of the rectifier tube had broken off and shorted out the socket. Two new type 06A tubes were installed and operation has since been satisfactory.

# AUXILIARY TANK

During the last refit #1 Auxiliary tank was scraped, wire brushed, and painted with Gilsonite. During the first week of January the fresh water became so rusty that an air pressure of 20# on the tank would not force water through the 3/4" line to the crew's washroom. The line was blown out, but immediately filled again with rust scales when the tank was put back on the line. On January 10th the fresh water in the tank was blown overboard. The Gilsonite coating apparently gave way allowing the fresh water in the tank to become rusty beyond use.

H. P. ATR COMPRESSORS

During entire patrol #1 air compressor was not operating correctly. Valve trouble was believed to be the difficulty in that the 3rd stage was running low and the second stage high. The second stage blow down had

— page 227 —
1. U.S.S. ANGLER - Report of Sixth War Patrol
: (K) MAJOR DEFECTS & DAMAGE - HULL AND MACHINERY (con-)

to be cracked to prevent lifting the relief. New valves and reground valves were inserted giving partially satisfactory operation for a day or so then the same trouble all over again. At one time the compressor had to be operated with both the 1st and 2nd stage blow down half open causing such a low pressure in the third stage that the compressor would not compress against a pressure of 1800 psi in the banks.

Excessive carbon deposits were found on 1st, 2nd, and 3rd stage valves that were reground indicating possible bad rings.

Upon arrival at Saipan 3rd and 4th stage rings were inspected. All rings were either broken or in bad shape. After re-ringing these stages compressor operated very satisfactorily.

TRIM PUMP (COULD TYPE)

The trim pump at various times during the patrol became air bound to the extent that the pump would take only a partial suction or no suction at all. By operating the vacuum pump continuously the pump operated to partial capacity. Numerous air leaks were stopped in the lines between the trim manifold and the vacuum pump which permitted the pump to take a proper suction for a time.

On January 24th complete suction was lost with vacuum dropping to 14 inches. A gasket on the strainer was renewed and during the remainder of the patrol no further trouble occurred, until February 2, when a leak developed in the flexible coupling on the suction side of the trim pump. Upon arrival at Saipan the Tender found rubber gasket in bad condition and the coupling out-of-line. Emergency repairs were made by Tender, silver soldering joints of this coupling thus eliminating leaks.

SHALLOW DEPTH GUGGES

During training period, trouble was experienced with depth gauges with variable errors from 5 to 40 feet. In spite of two tender overhaul the same trouble was experienced on leaving for patrol. Upon return to Exmouth Gulf, W. A. on 20 December 1944 depth gauges were exchanged with the USS ERGALL. Since that time no trouble has been encountered with the shallow water depth gauges.

1. RADIO
The only radio material accurately encountered was poor commutation in the TEL motor generator which caused a low fluctuating value for the filament voltage of the master oscillator. Adjustment of the brushes corrected this.
VTXO reception was consistently good at night. During the morning the signal strength was low; occasionally the signals faded out. In the afternoon reception was poor but could be copied.
The best reception on NPM was on 909C kos, especially during the times that that frequency was broadcast from Guam. When 9090 kos faded 6045 was usually strong enough for reception. During early morning hours 4515 could be copied. There were periods in the early morning when all frequencies faded out.
The Voice of Freedom station located in China, using a frequency close to 6045 kos interfered with reception on that frequency. Signals could be copied through the music but difficulties were encountered getting a good copy of weak signals.
Some difficulty with transmissions was experienced. On January 27 from position southwest of Formosa, one hour and thirty two minutes were required to send a 44 group message to NPM on 4235, 8470 and 8290 kos. The message was finally cleared on 8470 kos and an authenticated receipt was received at 0900Z. Transmission started at 0728Z.
An attempt to raise Saipan (NDP4) on the first of February using 4155 and 8310 kos commenced at 1248Z. There was considerable traffic on frequencies near 4155 but no response from NDP4 was obtained. At 1345Z NPM was raised on the first call and the message was cleared through him at 1405Z. His signal came in strong and clear. 4235 kos was the frequency used. Later that night NDP4 was heard clearly on 4155.

13. The health of all hands was excellent throughout the patrol. There were the usual minor injuries and illnesses which were successfully treated by the pharmacist's mate.
14. The food was chiefly Australian and was normal to that locale.
15. Habitability was generally good although there is certainly a definite need for an additional air conditioning unit to service the forward part of the ship.

20. (d) Number of men qualified at end of patrol 6
21. (e) Number of unqualified men making their first patrol 10
22. The training of officers and crew has progressed very satisfactorily. Although no actual combat conditions were experienced the conduct of all hands, during the period the BERGALL crew were aboard and during our transit of Lombok Strait on December 24, was excellent.
23. Considering the heavy loss of officer personnel to this ship at the end of the last patrol, and that all officers with one exception were new to their jobs, the Commanding Officer has nothing but the highest praise for the outstanding job they did. Particularly noteworthy was Lieutenant-Commander L. R. VASEY as Executive Officer and Navigator whose performance of duty left nothing to be desired.

6. Was radar used for surface or air search - Surface Search
Evidence for this conclusion - Three of the four occasions this frequency was encountered were were later forced to dive by night flying planes.
7. Action of enemy radar: Intercepted at frequent but irregular intervals all three nights. Usually increased in intensity until contact was made with plane by radar.
8. Narrative: Submarine was forced to dive frequently all three nights. Increased intensity of interception was usually followed by plane contact. The contacts closed rapidly until we dove. Occasionally plane would close to approximately fourteen miles accompanied by increasing volume of reading on APR after which plane was cut to a range where contact was lost on rail. The plane would apparently secure his transponder and close again at a low altitude so radar contact would be made at ranges of only seven miles. Flares was closing rapidly when we submerged. This process was repeated several times. Twice IFF signals were exchanged but plane continued to close.

looked more like a marine disaster than the
result of torpedo fire. It 1FC0 works it
looked in fair condition, so could not have
been there too long a time. There were some
rocks outboard of the bow half but believe a
torneo would be able to work it. It ap-
pears as though it could be salvaged. Did
not shoot one at it for follow reasons:
(1) as just starting patrol for day and
there was no sense in startling the natives.
(2) In all probabilities, so other boat has
put her up there in spite of our beliefs that
she ran around. (3) the crew are always
boats in this area, it can be watched and the
local center of WCRI SALT & 3000 can
be reduced to zero, in attempt to salvage
this ship is made.

Gun Attack No. 1, Patrol No. 7.
Time: 1759. Date: 7/26/43 Lat. 3E-16.5N, Long. 141.35.5E.

Target Data - Damage Inflicted

Damage: Japanese installations on KITASAN ISLAND.

Damage det- Saw hit in building. Sew cloud of
errained by smoke and debris in and over target.

Details of Action

Spent several hours submerged examining area
at ranges between 5,000 to 7,000. Target consisted
of at least ten buildings, 2 large radio towers, and
lighthouse, along with 5 more buildings and towers
stretching up hill in backaround. Area selected for
bombardment was closely bunched buildings and towers of
main establishment. Aproceeded submerged, keeping ship
well clear of restricted area to seaward and shoal water
along island. Had to enter a funnel to get in position,
swung submerged to 0.5(?) end surfaced. Range to tar-
get 3,200 yards. "hole target area sets on plateau
about 150 feet high with a sheer cliff facade us. Plan-
ned to use 5T radar for ranges and spot by scope. Open-
ed fire at about 3,400 yard range maintaining stercage
way only on the battery. First round entered main
building in vicinity of front door. Periscope fogged
at this time, as did gun sights. Shifted spot to
bridge and used open sights, and went to hand firing
due to foot firing casualty on five inch. Each round
had spot set in. Damage assessment after first round
could not be made due to smoke in target area. "over
spotter was able to see flash of burstine shell, of
twenty-five rounds expended, twenty fell within 200
yards of main establishment. Maximum range was 4,000
yards on last two shells.

Ammunition Expend: 25 rounds 5".

Target Data - Damage Inflicted

Damage: Unknown.

Damage determined by: Heard several explosions and radar reported change in shape of "pipes."

Details of Action

Spent full day submerged off this city. Used ST throughout day, so radar operator thoroughly familiar with shape of "pipes" on face, tower, power plant, cranes, and kindred installation. Visibility excellent when we started submerged approach. Planned to shoot from 10 fathom curve riv- ing a range to target of 5,000 yards. Drew city to scale on cross-section paper and planned to saturate factory and power station by 500 yards in depth, and right and left 500 yards. Fog closed in before we had attained position. With visibility zero, surfaced on 10 fathom curve, stopped and used radar to pick out factory and power station installations. But them dead astern keening storeggway and commenced firing with range to factories about 5,200 yards. Kept main body of buildings dead astern. "put spot in for each round fired via ST Radar, spotting right and left to give area good coverage. Believed it impossible to have missed with any. Target area was so wide and so deep it was almost a "cow and banjo" set-up. Sea conditions were zero.

Ammunition Extended: 50 rounds 5".

2. (I) MINES
3. Several floating mines were encountered. Destruction was not attempted due to weather conditions, or the time element. No minelaying operations were noted. We submit the following negative information: There are apparently no mines in SAGEWA WAN, north of KINKASAN ISLAND. There are apparently no mines on the south coast of HOKKAIDO between Long. 141-30 E, and 141-45 E, outside 10 fathom curve.
4. On July 26, after boarding KINKASAN ISLAND, four A/S vessels appeared around the south tip of the island, but headed to seaward for about there are some mines at the southwest tip of KINKASAN which they had to avoid. There could be no doubt that they saw us.

8. Hull and Machinery.
9. (1) On 19 July a leak occurred in the thermometer element of the type 40131 Bathymetrograph. This leak was between the Bourdon element and the capillary tube, and permitted the xylene to leak out of the element. The Bathymetrograph was out of commission for the remainder of the patrol. No spares carried on board to repair.
10. (2) On 27 July an inspection of the lub oil flexible coupling on No. 2 main engine showed a small blister. Engine was out of commission for one hour while the coupling (EB drawing No. 207261, Items 5,6, and 7) was renewed from on board spares. This casualty has occurred previously on two other main engines. The alignment of this line was checked, but showed no indication of being out of line, and thus causing the trouble.

(K) MAJOR DEFECTS AND DAMAGE

Hull and Machinery. (Continued)

At the present time, an average period of 4 minutes and 20 seconds is required for the hydraulic plant to cycle. It is believed that leakage in the main hydraulic manifold operating gear and/or a possible leak by the non-return valve causes this short cycling time. The filters in the system have removed most of the foreign matter, but not before considerable damage had been done.

(7) Air bubbles from bow buoyancy tank have been a constant source of worry the whole patrol. Bow buoyancy blow valve was relapped twice to no avail. High pressure air to bow buoyancy was secured at the high pressure air distribution manifold, and the stem and seat were removed from the bow buoyancy blow valve. After rocking the boat through 5°, bubbles were still observed to come from bow buoyancy tank, and they can be seen even after an all-day dive.

An air trap in the top of bow buoyancy tank is believed to exist, due to improper venting of the spaces between strength cross-members.

(8) After two days on patrol, the liquidometer gauge on safety tank became unreliable, showing 1 full when tank was completely flooded.

(9) On 9 July the starboard sound head hand-training gear was removed due to noisy bevel gears. Attempts were made to line up gears and the thrust bearing was tightened, but to no avail. This failure is believed due to faulty installation at BETH-LEPSEY STEEL CORPORATION. The gears were not lined up properly, and subsequent wearing produced an excessively noisy training system.

15 JULY 1945 - Report of SUBMARINE WAR DEPARTMENT.

(K) 1st JUNIOR DEFECTS AND DISCHARGE

Ordnance and Gunnery.

(1) Failure of semi-automatic breech operation of 5"-25 cal. deck gun.

This casualty first appeared during bombardment of KITZIGAM 25 July 1945. On the last five rounds, breech had to be opened by hand. Examination of gun showed no apparent cause.

During subsequent bombardments, breech failed to operate on four or five rounds of each action.

"To definite cause has been found. Possible causes may be faulty recoil, sticky cam plate, or excessive wear of cam plate, permitting cam follower to slip past cam plate instead of following cam surface.

(L) RADIO

(1) Material condition of the radio gear was good through out the patrol. The only major casualty occurred on 10 July when the CC printed galleys and indistinct characters and was useless as far as decoding messages was concerned. . . . after consulting the instruction book, repairs were undertaken and a defective felt washer (Part "O, 76084) which drives the type wheel was replaced. To further trouble was had with this gear.

On 15 July it was noticed that the plate relay in the WIP was sluggish in action, but by straightening and cleaning the contacts, the condition was remedied. The WIP was manned constantly while on the surface, and its performance was excellent in all air-sea communications. It is felt that with the amount of use this unit is getting, a complete set of spares should be made available.

The SCR 610 proved to be a valuable addition to the radio gear being used for all short range communications between boats.

(2) As a general rule, the best reception of SubBox was on 9090 Kc's. at night and 13665 Kc's. during the day. Only one SubBox Serial was missed, and it was received the next day from the SEA POLICER when channelling areas.

Three messages were transmitted during this patrol. The first on 0470 Kc's. to YM was cleared in twenty minutes from the preliminary cell-up. It was sent at 2305 (7) on 1 July in Lat. 30-53 N. Long. 139-03 Z. Our second was also taken by YM using the same frequency at 2015 (I) in Lat. 37-20 Y. Long. 142-25 Z. on 25 July and was cleared in seventeen minutes. The third transmission was attempted on 0470 Kc's. at 2330 (K) on 2 August, in Lat. 43-09 Y. Long. 146-23 Z. with a-iving us signal strength zero to one, and his signal coming in about the same. After listening to traffic on other ship-chore frequencies, noting that crew were having trouble, and trying one more call with no better results, we decided to wait until the next night at a different time. The same message was sent at 1940 (X) on 3 August, in Lat. 43-14 Y. Long. 154-17 Z. on 0470 Kc's. at 7:30 and was cleared in 14 minutes from the first call-up. Both YM's and YM's quick, accurate atttachment in the preliminary cell-up greatly expedited the time required to clear our traffic.

Only one transmission was made on SLP plan frequencies, and no difficulties were encountered.

(1) R D/R

The racers were rigged with a series of casualties, chiefly of a minor nature, which necessitated constant attention to the gear. The poor visibility encountered increased the dependance on the gear and also reduced the time available for routine maintenance work to a minimum. A total of 1,000 hours was not on the SLP and 1300 hours on the SP.

7MC
Poor contacts on the station selector switches and press-to-talk switches of busy stations in the 7MC system, caused occasional faulty operation. No appreciable time was ever required to correct these.

The springs on the press-to-talk switches, on both coming tower stations, and the diving station broke, causing the affected station to be cut out of the system when the switch was released. These were all repaired easily, while the auxiliary talk-back system, carried prior to the installation of the 7MC and reinstalled after overhaul, carried the load during repair-periods.

21 July, after patrolling submerged all day, sweeping
with the ST in var moor visibility, was surfaced 10,000

navitectional fix. After sweeping at high speed for
several minutes, the ST turned and echos were com-
pletely obscured on both the PT and "U" seaports by

so strong it could be picked up on all bearings, but
appeared to be strongest toward land (2700 T), al-
though no accurate bearing was possible due to the

The initial period of jamming lasted for about two minutes, followed by a thirty second break. He then opened up for an hour minute. The SJ trans-mitter was secured and he keyed a few more times with longer intervals between signals, then secured completely. The SJ was not used for the transmitter of the time sent in that era and no further activity on the part of the tanner was noted.

(3) Deception, Own.

While near the J.P.MESE coast, surface searching was done chiefly with the SJ. When the SJ was employed, it was keyed for three minutes. When not transmitting, a watch was maintained searching for SJ frequency interceptions.

When the SD was employed, it was keyed for five seconds at approximately two minute intervals, with stress on varying the interval between sweeps. In using this type sweep, no planes were encountered close aboard without having been detected first at safe range.

(1) On 21 July each range in 15 Kcs. was detected by CE in Lat. 35-02.0 N, Long. 141-52.0 E. The ship which was each range was not sighted or identified.

On 25 July after torpedo attack in Lat. 38-32.5 N, Long. 141-57.7 E, target commenced to echo range at 17.8 Kcs. using 4-5 second intervals during entire period of search. Ship did not make contact.

On 26 July each range was detected on 1.0.0 Kcs. by B. Range to target by ST Radar a short time later was 7,000 yards. A 4-5 second interval was used between transmissions. Ship was not sighted or identified.

1. The seventh war patrol of the ANGLER, under the command of Lieutenant Commander H. Bissell, Jr., U.S. Naval Reserve, was conducted off the East Coast of Honshu.

2. This patrol was mainly an offensive patrol. Three days were devoted to lifeguard duties. There were no opportunities to recover aviators. The ANGLER was a member of a coordinated submarine group which conducted surface sweeps for patrol boats in advance of the Third Fleet's approach to the Honshu Coast. The ANGLER covered her patrol area in a very thorough manner and resorted to one- or two-rollings in endeavors to seek out worthwhile torpedo targets. The ANGLER was also navigating and searching for about ninety per cent of the time in the area and navigation and searching for about ninety per cent of the time. Only two contacts were made during the patrol. The other, a small AK or Kuru type anti-submarine vessel, was lost with three torpedoes. The ANGLER was not a submarine vessel, but a submarine. The ANGLER was not a submarine

1. Received CTF 71 dispatch changing patrol area and assigning special mission to the Angler. Proceeding to new patrol area.

March 18, 1944 Received CTF 71 dispatch directing us to rescue "about fifty" United States citizens from a signaled rendezvous position on the north coast of Fanay. This message increased the number of evacuees from twenty, as indicated in the first message, to fifty including women and about half of the total to be children.

March 19, 1944 Received CTF 71 dispatch confirming his dispatch of the previous day and indicating the necessity of embarking the evacuees on the first day of the rendezvous.

March 20, 1944

(I) 0433 Submerged eight miles south of rendezvous point and stood in toward the beach.
0730 Began reconnaissance of rendezvous area, two miles south of designated embarcation point. No signals in sight.
0908 Moved in to one mile and saw large crowd of people walking behind the tree line on the beach near rendezvous point.
0958 Observed "huge" preseribed signals being hoisted in trees along the water's edge. Stood out to seaward about five miles where we could still see the signals very clearly.
1500 Stood in toward rendezvous point.
1717 Went to battle stations and assembled special details.
1730 Saw evacuees gathering around three sailboats on the beach.
1801 (Sunset 1803) Surfaced, decks awash - stopped parallel to beach - distance 1000 yards. Manned twenty militesters and thirty sailor machines guns.
1821 Received small banca alongside containing Liut., Colonel Garcia, Captain Hawley, 1 soldier and 2 boatmen. Informed that there were 58 evacuees and asked if we could take all. Colonel Garcia sent affirmative signal with flashlight to the beach - party started toward the ship in sailing bancas.

0800 Anchored off Dudley Point, Darwin and disembarked evacuees to tender.

REMARKS:
1. Passenger list (Enclosure B).
2. The entire ship's company was berthed in the after battery except for torpedo room watch standers. A Chief Petty Officer was placed in charge of each torpedo room. Men and boys lived in after torpedo room, women and children in forward torpedo room. CFO quarters were inhabited by one woman with a two months old baby, one pregnant woman (8 months), one seriously ill girl (worms - temperature 104°) and two elderly women.
3. Ship was immediately infested with cockroaches, body lice and hair lice. A large percentage of the passengers had tropical ulcers plus an odor that was unique in its intensity. All passengers showed signs of prolonged undernourishment. All passengers were suffering from lacerated feet due to the long march to the embarkation point without footwear.
4. One male passenger was temporarily insane, requiring a twenty-four hour watch.
5. Two meals a day with soup at 2400 was put in effect at once, since it was apparent the ship did not have enough food aboard for a full three meals each day. Passengers ate ravenously from their arrival until they left the ship - food was rationed until the night prior our arrival Darwin when we fed a "Shipping-over" chow, and our supply of provisions was practically exhausted. Three messes were served; first, officers and crew; second, women and children; third, male passengers.
6. Habitability forward of the control room resembled the "Black Hole" of Calcutta - a condition which resulted from children urinating and "splitting" on the deck, body odors and forty-seven persons sleeping forward of the control room. In spite of a constant watch on the head, it proved impossible to teach our passengers the proper use of this vehicle after two years in the "hills". A suction had to be pulled through the boat as many as three times during the night in order to change the heavily laden air.
7. "Highlights" (a) The mental incompetence of paragraph 4, graciously presented each member of the crew with a gold mine - promising to make them all millionaires. The Commanding Officer was made chief engineer in charge of mining operations.

— page 302 —
7. "Highlights" (Cont'd.)

(b) The first night aboard one Army Captain paid our enterprising ship's cook 100 pesos (cash) for 25 apple pie. This money had been printed personally by this same Captain, while a member of Garcia's guerilla army, competing successfully with the Japanese occupation "peso".

(c) One for the book was the sight of a two year old half-filipino boy smoking (and inhaling) a cigar between gulps of his dinner which he was receiving at his mother's breast.

(d) A sight long to be remembered was that of two children perched in an upper bunk picking lice out of each other's hair and cracking same with their finger nails.

6. Upon arrival Darwin the following two days were spent rehabilitating the ship, removing mattresses up into the sun and scrubbing down completely with hot soap and water and carbolic acid disinfectant. Numerous anti-roach and lice bombs were used in both torpedo rooms and CPO quarters which were completely disinfected.

attack expended CREVAILLE's torpedoes and she returned to base. The ANGLER patrolled independently until 10 August in South China Sea but the patrol was uneventful.

5. The remarks and estimate of damage by the group commander are concurred in. The excellence of communications is most gratifying.

6. The attack by the group on the large convoy off the Philippines on 25-26 July 1944 was outstanding, both as to results obtained and to method of execution. In the face of heavy air and surface coverage, all submarines pressed home their attacks in a manner which reflects great credit on the courage and skill of the three commanding officers and their ships.

7. The squadron commander takes great pleasure in congratulating the group commander and the commanding officers, officers and men of the individual submarines on a job well done.

Consisting of U.S.S. FLASHER, U.S.S. CREVALLES, and
U.S.S. ANGLER from June 19, 1944 to August 23, 1944
report of.

1. This Coordinated Attack Group conducted operations in
the SOUTH CHINA SEA.

2. Only one convoy was attacked by all three ships as a
group. ANGLER sighted and reported a large convoy shortly after sun-
rise July 25th. Each submarine made one submerged approach during
daylight, but due to radical changes of base course, only CREVALLES
was able to reach a firing position. Her attack was unsuccessful
because of poor visibility. FLASHER regained contact with the con-
voy after dark, but refrained from attacking until at least one
other submarine had also gained contact, since she had only six tor-
pedoes remaining. This proved to be a sound decision. It is un-
likely that either of the other ships could have regained contact
without the excellent information provided by FLASHER at frequent
intervals. FLASHER attacked at 0213 the next day, shortly after
ANGLER reported being in contact. In a night surface attack she sank
one large AO and one large AK, and damaged another large AK.
ANGLER attacked next at 0400, damaging and probably sinking a large
AK. CREVALLES attacked at 0430, just prior to dawn, sinking two large
AK's. Unfortunately, all three submarines were forced to dive after
their attacks, and contact with the convoy was lost. During the
forenoon, however, CREVALLES sighted and sank the large AK previously
damaged by FLASHER.

3. The Task Force Commander concurs with the remarks of
the Coordinated Group Commander. The necessity for each submarine

Corsairing off S.S. STARFLEET, 1.3.3, CREVALLI, and
U.S.S. ANGLER near the 1.1944 to August 23, 1944
report of:

making every possible effort to maintain contact with the convoy
cannot be emphasized too strongly. If this is done the chances are
excellent that at least one ship will be able to make a successful
end-around run. CRYSTAL demonstrated that it could be accomplished
during daylight, in spite of air cover.

5. The coordinated Attack Group is credited with having
infiltrated the following dangers on the enemy:
