7 August 1944
: USS BASHAW (SSK 241) (EX SS 241)

As the American offensive rolled across the Pacific, submarines were employed to support actions as pickets, weather stations, and landing reenactments to his great sea empire, boldly pursuing and attacking shipping in Japanese home waters.

The history of the USS BASHAW began on 4 December 1942, when her keel was laid at the Electric Boat Company, Groton, Connecticut. She was named for the large cat-fish which is commonly found in the Illinois and Mississippi Rivers. At the launching on 25 July 1943 she was sponsored by Mrs. N. M. Ives, wife of Captain Norman S. Ives. On 25 October the BASHAW was commissioned and turned over to her first commanding officer, Lieutenant Commander R. E. Nichols, USN.

Extensive training exercises were conducted in Long Island Sound, Key West, Florida, and off Perias Islands, Canal Zone. Then on 3 March 1944 she arrived in Milne Bay, New Guinea, and reported to Commander Task Force 72 for duty. Seven days later the BASHAW steamed out on her first patrol in company with the USS BLACKFISH. At this time the Japanese Fleet was stationed at Tawi Tawi in the Sully Archipelago. They were expecting a thrust at the Marianas and a simultaneous strike at Iwewak, New Guinea. This concentration was an effort to base the fleet as close as possible to these scenes of impending action. As a counter measure, American submarine were stationed on the arc of a circle with a 60-mile radius from Togel Milungu Passage, to cover all escape routes. The BASHAW was placed southeast of Mindanao to cover that route to the Marianas. The submarines shifted into intercepting positions from day to day as information on the Japanese fleet was received. The BASHAW's first opportunity for action came on the night of 21 March 1944. In a surface radar attack she fired six torpedoes for one hit on a 4,500 ton submarine tender. Position could not be gained for further attack, but the damaged ship was sunk the following day by a carrier plane. In a daylight surface attack on 27 April the submarine demclished a 50 ton trawler with the 4-inch and 20 mm guns, and damaged three 60-ton trawlers. On 10 May she returned to Brisbane, Australia for her first routine refit.

The BASHAW nosed out of Brisbane on 27 May headed for areas adjacent to Mindanao and the Celebes Sea to conduct her second war patrol. On 25 June the 6,440 ton transport YAMAMIYA MARU was contacted. In a night surface radar attack six torpedoes were fired for three hits, sinking the transport. This was the only contact of the patrol, and on 16 July she moored alongside the EURYALE at Seeadler Harbor for refit.

Training exercises were conducted following the refitting, but by 7 August the raider was steaming out for her third patrol along the Mindanao coast in the Mindanao Sea and Moro Gulf. On 8 September a night radar approach was conducted on a 2,613 ton cargo ship. Upon closing the BASHAW surfaced to periscope depth and fired a six torpedo salvo. The salvo fanned out, scoring three hits to send the YANAGIGAWA MARU to the bottom. The next day the BASHAW

took lifeguard station for the carrier air strikes on Cagayan, Mindanao in the Philippine Islands. The same day she concerted her efforts with four "Hellecats" to sink a 225 ton inter-island supply ship which was loaded with drums of fuel oil. One prisoner was taken aboard from the sinking ship, and turned over to Allied authorities at the end of the patrol. On the 19th a fighter pilot was rescued. The BASHW then returned to Brisbane, arriving 4 October 1944.

The submarine commenced her fourth patrol on 27 October as a member of a wolf pack with the GUAVINA and FLOUNDER. The hunting grounds for this foray were the vicinity of Tizard Bank and the coast of Indo China. By this time targets were becoming harder to find, but on 21 November a 5,000 ton tanker crossed the BASHW's track. After a daylight periscope approach, four torpedoes were fired to score one hit. No further attack was made on the damaged tanker. Continuing the patrol in the South China Sea, a large enemy task force was sighted on 14 December 1944. Unfortunately the force was so heavily escorted the BASHW had to content herself with sending a contact report. Christmas Day the submarine made a submerged transit of Lombok Strait on her return run to Fremantle, where she arrived December 31st.

During the refitting period Lieutenant Commander Hoke S. Simpson, USNR relieved Commander Nichols as skipper. On 26 January 1945 the BASHW steamed out on her fifth patrol to be conducted along the east coast of Hainan Island, the eastern part of Tonkin Gulf and off the northeastern coast of Indo China. A 250 ton sea truck was sunk with torpedo fire on 10 February, and the same day she coordinated with the FLASHER to sink another 150 ton sea truck with gunfire. An unsuccessful attack was made on a small escorted freighter on the 25th. Then while the BASHW decayed the escort the FLASHER finished off the freighter. She joined with the FLASHER again on the 27th to sink two 70 ton sea trucks with gunfire, and damaged two more 250 tonners the next day. The BASHW's luck improved on 5 March when, while patrolling in the vicinity of Hue, a 10,000 ton tanker was contacted. Groping her way through a murky fog, the sub gained attack position and fired six torpedoes. Two good hits were scored, sending the RYOEI MARU to her grave. This was the last 10,000 tonner torpedoed in the South China Sea. The next day another 250 ton sea truck carrying Japanese Marines was sunk with 4" gunfire. The BASHW ended the successful patrol on 12 March when she moored alongside the GRIFFIN in Subic Bay.

She departed on the sixth war patrol on 27 March 1945. This was conducted in areas of the Indo China coast and the east and northeastern coasts of Hainan Island. No worthwhile contacts were made, and the sub returned to Subic Bay on 29 April for onward routing to Mare Island, California, and her first overhaul.

Upon completion of the overhaul on 13 August 1945, she departed for Pearl Harbor. The war ended while enroute, and the BASHW returned to Maro Island.

During her wartime career the USS BASHW earned five Battle Stars on the Asiatic-Pacific Area Service Medal for participating in the following operations:

2028 (K)  Ladder contact at 9500 yards.
2038 (K)  Total of three, possibly four contacts at intermittent intervals, ranges 8,700 to 9,500 yards.
    - Apparently very small targets as radar had been getting ranges of 12,000 to 13,000 yards on ships the size of the U.S.S. COUCUL.

Challenged shortly after this by flashing light from the escort. Doubt that we were seen. Was making high speed to gain a favorable attack position. Believe we were picked up by sound listening gear. Opened range to west.

As aiming another attack position would require more time during which time we would be "out of bounds", and in view of the fact that targets appeared too small for torpedoes decided to break off the attack. This time, and clear the way for the attack bombers. This decision was clinched shortly after this when we received CDR 72 serial telling us to cut north of the equator as it was search planes were after our contact. As we were probably the best "pip" in the vicinity, we ran clearing to the north at best speed. Indications on S.O of presence of radar equipped planes. Submerged, to insure that we were not the "target for tonight."

1402 (I) Sighted masts. (Ship contact # 4). Began closing on normal approach course. Shortly thereafter made out converted escort carrier, similar to OTAMA class, two escorts (FUJNI class destroyer, CHIQUI torpedo boat) and "Rufe" float plane. Course determined to be OIO true, speed 19 knots. Carrier was not zig-zagging nor were escorts echo-ranging. Angle on the bow at sighting 60 starboard. Never able to close to less than 10,000 yards.

This was a tough one to watch go by. In view of speed of target and air cover, decided surface chase is useless.

GUN ATTACK REPORT

U.S.S. BASHAM (SS241) GUN ATTACK #1 PATROL #1

TIME: 1930 K DATE: Apr. 27, 1944 Lat: 03-20.0 N LONG: 131-35 E

TARGET DATA - DANGER INFLICTED

SUNK: Two 60 ton trawlers.

DAMAGED OR PROBABLY SUNK: Two 60 ton trawlers.

DAMAGE DETERMINED BY:

Several hits and near misses with 4" 50 cal. H.C. projectile were scored on each of three of the trawlers. One hundred and twenty rounds of 20 MM HEI ammunition and 60 rounds of HET 20 MM ammunition were fired into the fourth at point blank range, and the target ashore off apparently out of control. One target exploded following a 4" hit. A second target was left smoking badly from a hit in the early part of the action.

DETAILS OF ACTION

The targets for this action consisted of four unarmed trawlers of approximately 60 tons each. Target was closed on the surface and fire was opened with the 4" gun at an initial range of 2500 yards. Radar ranges were used in conjunction with spotting from the bridge.

Thirty four rounds of 4" 50 cal. H.C. ammunition and three rounds of 4" 50 cal. cammunition were fired at an average range of approximately 200 yards. A total of 180 rounds of 20 MM HEI, 90 rounds of 20 MM HET and 450 rounds of 30 cal. were expended. Although 120 rounds of HEI 20 MM ammunition was fired into one target at point blank range, the target was not set afire.

The action was terminated at 2010 because of darkness.

— page 37 —
15 March and 21 March is believed to have been by sound listening gear as the attack was completed on 21 March with no evidence of use of radar by escorts.

(K) MAJOR DEFECTS AND DAMAGE:

Engineering and Electrical:

Pit log: - Pit Log swordarm bent after striking submerged object, Replaced with spare swordarm.

A main engine Salt after Pump: - Routine inspection revealed considerable fore and aft play in pump shaft. Removed pump and determined play to be caused by failure of pump shaft roller bearing. The inner race had carried away and outer race was cracked. Failure due to faulty bearing as three was no oil failure or evidence of foreign substance. Engine out of commission for 20 hours.

(K) MAJOR DEFECTS AND DAMAGE - Cont'd:
    Engineering and Electrical - Cont'd:

#1 Evaporator Compressor Motor: - Motor Armature began to smoke and caught fire on last day on station, Obtained a ground reading of zero on armature. Replaced defective armature with spare but found this latter armature also defective as it heated up considerably shortly after machine was started. Failure of motor did not cause any hardship as #2 evaporator was able to supply water needed during remainder of patrol.

Ordnance:

Torpedo Data Computer: On April 2, a routine check of the T.D.C. revealed that the after engine Solver was not operating properly. The after engine Solver following head was disassembled and the cause of the trouble was found to be the ball bearing thrust bearing on the shaft of the follow up head assembly. The ball bearings had fallen out of their retaining ring, which allowed the gear drive for the Inter Roller Contacts of the follow up head to disengage from the gear drive from the Position Keeper. The bearings were replaced and roller contacts readjusted. Angle solver tests then showed the unit to be generating correct values. The T.D.C. was out of commission for a period of 18 hours.

C and R:

#2 periscope: - Although #2 periscope was pulled, stoned, bearings checked, and periscope repacked just prior to leaving on patrol, it failed to eliminate binding and grating on certain bearings. The periscope was repacked at sea, and greased daily with no apparent success. The periscope would "free up" for a few hours and then the binding would suddenly reappear. A work request is being submitted to pull the periscope and check the alignment of the bearings.

(V) SOUND CHART AND SOUND CONDITIONS:

All sound gear operated in a satisfactory manner throughout the patrol without material failures.
Maximum ranges were as follows:

| Range | Conditions |
|-------||
| JU-1  | 14,000 yards - (echo ranging) |
|       |    | 15,000 yards - (echo ranging) |
|       |       | 9,000 yards - (screws of an escort) |
|       |       | 9,000 yards - (screws of an escort) |

Japanese echo ranging was tuned on our receivers at 16.5 and 22.5 kcs. during the March 21st attack.

(0) DENSITY INCREASE:

A density layer was encountered off D.V.O. Gulf, latitude 06-30 north, longitude 127-00 east, consisting of a ten degree drop in temperature from 140 to 300 feet.

Bathymetrograph tracings around D.V.O. and north of N.E. Gulf showed conditions to be nearly isothermal to 300 feet with occasional slight negative gradients.

(1) HEAT, FOOD, AND HEATABILITY:

All were excellent. There was no illness requiring medical attention except minor colds and lacerations. Both the quality and the variety of food retained high during the entire patrol. A good air-conditioning unit and much surface-running contributed to the general comfort of all hands.

(U) INSTRUCTIONS:
1. During this patrol the bridge force and craft spotters developed perforce, into the finest set of air-spite of this, however, and an attempt to avoid situations where aircraft had all the advantages, two situations occurred where planes "had the drop" on us. The early installation of a satisfactory aircraft search radar is believed of vital importance in continuing the obvious advantages of surface daylight patrol.

Subject:
U.S.S. BASHAW (SS241) First War Patrol - Comments on.

1. During this first patrol of the BASHAW, five ship contacts were made, only one of which afforded opportunity for torpedo attack. This was a five thousand (5,000) ton freighter with two, possibly three escorts, encountered in the late afternoon of 21 March 1944 off PALAU. Approach was continued on the surface after dark, and was nearly frustrated when one of the escorts challenged by blinker. One hour later, the attack was made; six torpedoes were fired, mean range four thousand (4,000) yards, 90° port track, 40° left gyro. The spread used ensured a coverage of 200% of target length. One hit was obtained; cause of others to miss is attributed to error in speed estimate. Difficulties in fire control were increased by pit log failure. The extreme range was imposed by the alertness of escorts and visibility prevailing. On 27 April 1944 a surface gun attack was made on four trawlers. One trawler exploded. Hits were obtained on the other three, leaving one smoking badly. The poor performance of the 20th incendiary ammunition is of note.

2. The Commanding Officer's comments in paragraph J, M and U on the unavailability of the SD radar are concurred in. In areas under constant air patrol, some form of adequate aircraft detection is a definite requisite to surface patrolling. Improvement to the SD equipment is considered one of the most pressing needs of the submarine service at the time.

3. The aggressiveness and tenacity of the submarine was demonstrated on this patrol. The Commanding Officer, officers and crew are heartily congratulated on the damage inflicted on the enemy.

SECOND ENDORSEMENT to

Serial 05 of 9 May 1944.
Report of USS EASHAW
First War Patrol

1. The remarks of Commander Submarine Division ONE EIGHTY-TWO are
   concurred in.

2. No major casualties occurred during the patrol. The below-average
   performance of the SJ-1 radar is noted. Ranges obtained are about half of what
   should be expected. The failure to detect planes is considered another indica-
   tion that performance is below average as experience of other submarines has
   demonstrated that the SJ-1 radar is an excellent aircraft detector and has been
   particularly valuable in preventing night search aircraft from executing sur-
   prise attacks on surfaced submarines.

3. EASHAW will be given a normal refit by the Submarine Repair Unit,
   Brisbane, Australia. It is anticipated that all deficiencies can be corrected
   in the allotted time.

4. The patrol was well conducted with commendable determination being
   displayed in the prosecution of all attack opportunities.

5. The Squadron Commander congratulates the Commanding Officer,
   officers and crew on the damage inflicted upon the enemy during their first
   war patrol.

Subject: U.S.S. BASHAM (SS241) - Report of First War Patrol comments on.

1. The First War Patrol of the BASHAM was the first patrol of the Commanding Officer as such. Sixty-one days were spent on patrol, of which four were under the operational control of Commander Task Force SEVENTY-ONE, and twelve were spent enroute to and from SEABLAD R HARBOR for refueling in mid-patrol.

2. Two contacts worthy of torpedo attack were made. BASHAM was unable to close range on the second contact which consisted of a high speed task force of one CVE escorted by a destroyer and a torpedo boat plus air cover. Six torpedoes were fired at the URAKALI HAU in the first attack and one hit was obtained. Long range made a small error in estimated speed critical and caused the other torpedoes to miss. This target was later sighted and sunk by aircraft during strike on PALAU.

3. This patrol is designated as "successful" for purposes of award of Combat Insignia.

4. The Commander Task Force SEVENTY-TWO congratulates the Commanding Officer, officers, and crew of the BASHAM for inflicting the following damage on the enemy:

1635 (I) Picked up echo ranging on approximate bearing on which masts had been sighted. Headed down true bearing with echo ranging apparently growing stronger but nothing seen in periscope.
1837 (I) Surfaced and continued down last true bearing making radar search. Echo ranging ceased immediately on surfacing. No further contacts. Masts were never seen by Commander Officer, but believe this may have been an escort vessel making high speed with a large angle on the bow when first sighted and that echo ranging was a ship noise aided and abetted by a little imagination as nothing further was heard after surfacing.

17 June 1944:

0105 (I) Radar contact bearing 170 true, range 22,000 yards. Commenced tracking and working ahead. Target appeared to be a fairly large nav with three escorts, one on each bow and one astern. Base course computed as 250, speed 9.5 knots. Contact of yesterday afternoon may have been an escort coming out of DAVAO to meet this ship.
At about 17,000 yards began to get "railings" on the ST from the direction of the target. Railings indicated about a 10 second rotating search interval. As no other submarines were in the vicinity, believe at least one of the escorts was equipped with surface search radar. Tracked at 15,000 to 16,000 yards and apparently not detected.

17 June 1944: - Cont'd:

0355 (I) In position ahead of target on base course, range 14,000 yards.
0412 (I) Submerged to radar depth. This was an error in judgement on the part of the Commanding Officer. Should have waited another twenty minutes to insure plenty of light for a periscope attack. In view of glassy calm sea conditions had planned a radar depth - periscope attack with target silhouetted in early morning twilight and rising moon. This plan collapsed when the target ran through the edge of a rain squall at the crucial stage.
0512 (I) At generated range of 5,000 yards went to periscope depth in view of suspected radar on escorts. Unable to pick up target on the 5J up to this time. Radar had been working beautifully before we dove. Heard leading escort go by. Visibility improving rapidly but with a rain squall background was unable to see target at all. Heard target go by shortly after. As had had no ranges since submerging, considered sound shot would have been a waste of torpedoes.
0635 (I) Surfaced and commenced another "end around" on four engines.
0820 (I) Submerged to avoid aircraft. (Plane contact # 10). May have been air cover for target coming out from DAVAO. Sighted coming out or clouds. Conditions very poor for sighting aircraft.
0900 (I) Estimated at this time that target would be in DAVAO gulf before we could gain another attack position ahead even if no further interruptions by aircraft which appeared unlikely. Abandoned chase and remained submerged to shift and route into torpedoes, three of which had flooded during the first approach. This is evidently not our day.

24 June 1944:
2059 (I) Surfaced and began closing to radar range.
2110 (I) One radar contact at 18,000 yards. Commenced tracking and working ahead. At least two escorts echo ranging. On closing to develop escort situation had total of five targets on radar. Resolving information from radar plot, masts seen through periscope before dark, and contacts the next day estimate the group consisted of one large maru, one small escort maru, two gun boats and one Pc. Radar indicated one escort on each bow, one astern, and small maru about 1,000 yards on far side of large one. Only the large maru and the near escort were seen during the firing.
Convoy apparently intended to skirt the east coast of KABOBOEAN ISLAND arriving at the southern tip or possibly SALEBABOE anchorage shortly before daylight. Estimated that a night surface attack had the best chance of success. Night was dark but clear except for a low surface haze. Sea was glassy calm and highly phosphorescent.

25 June 1944:
0229 (I) Fired six torpedo spread at large maru.
0231 (I) Three explosions observed on or near target. Three heard on sound gear. Only one heard below decks. Target began emitting large clouds of smoke. With the firing set up doubt that more than two hits could have been obtained on large maru. Inird explosion possibly a hit on the escort maru on far side of target or an internal explosion in the large maru.
Began evading on the surface. Near escort at 2700 yards after firing but apparently did not see us in spite of very noticeable wake. Radar pip on large maru decreased to about half size shortly after hits observed, and disappeared at about 11,000 yards.

25 June 1944: - Cont'd:

Foreshortening of target due to turn away could have caused this, although target was first picked up at 18,000 yards with a small angle.

Commenced reloading torpedoes.

0422 (I) Reload completed. Returned to scene of firing.

0458 (I) Submerged.

0600 (I) Sighted smoke bearing 298 true. Made out masts and funnel of ship. Echo ranging from this direction also. Began closing. Not the same ship fired at. May have been escort maru or one of the escorts of last night. Ship disappeared on the same bearing about 15 minutes later, echo ranging drew around to the south. Heard echo ranging and observed smoke on about 180 true at this time.

0724 (I) Heard distant explosion.

0737 (I) Sighted masts and smoke from second ship bearing 180 true. Echo ranging from this bearing. Closed to investigate. Identified as HASHIDATE class PG searching area on a northwesterly course.

0914 (I) Sighted masts and funnel of a second PG bearing 180 true, also echo ranging and searching area. Heard echo ranging on two different frequencies from this direction. This group searched area until about 1200. No sign of large maru.

1200 (I) Zone - 9 Lat: 03-56 N. Mi. Steamed: 141 Long: 127-26 E Fuel Exp: 955 gal.

TIME: 0229 I DATE: 6-25-44 IAT: 3-36 N LONG: 127-14 L
TARGET DATA - DAMAGE INFLICTED
DESCRIPTION: Convoy consisted of five ships; one large
maru, three escorts and possibly one small escort
maru. Targets were contacted by periscope in late
afternoon and were tracked by periscope and later
by radar. The night was dark but clear except for
a low surface haze. Sea was glassy calm and highly
phosphorescent.

SHIPS SUNG: NONE.
SHIPS DAMAGE OR PROBABLY SUNG:
NUMBER TYPE TONNAGE NAME (IF KNOWN)
1 Transport Medium Similar to YOSINO MARU (EU)
DAMAGE DETERMINED BY: Saw and heard # 3 torpedo hit.
Brigue personnel also saw flashes corresponding to
times for # 4 and # 5 torpedoes to hit but no explosions heard below decks. Sound operator reported three explosions.

OWN SHIP DATA
SPEED: 2 kts COURSE: 184 DEPTH: Surface ANGLE AT FIRING
FIRE CONTROL AND TORPEDO DATA
A night surface radar attack using TBT bearings during
late stages and before each shot. Convoy was zigging at
short intervals (5 to 8 minutes) on base course 320 true,
speed 8 knots. Used 200% divergent spread on 60-70 starboard track at an average torpedo run of 4200 yards.
Very noticeable wake and proximity of near escort prevented smaller firing range.

I. MINES:
No information.

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS.
No new measures encountered. Definite evidence of radar on escort or escorts of ship contact # 2. Some evidence of radar equipped planes in area. May have been friendly. (See section M).

K. MAJOR DEFECTS AND DAMAGE:
ENGINEERING DEPARTMENT:
On June 5, 1944 the salt water pump on # 4 main engine was replaced. Water had been allowed to accumulate in the casting. This entered the bearing causing the double ball race to burn out. Engine hours - 1342. Pump replaced from spares.

After 91.5 hours operation water was found in the oil at the drive end of the blower of the #1 evaporator. The rotary seal, seal bushing, and gear plate ball bearing were replaced.

While maneuvering alongside the U.S.S. EUGY-ALE on June 4, 1944, the following casualty occurred in the cubicle. With the battery selector in the "both batteries" position, the port motor starter was put in the "ahead" position. Immediately there was an arc at relay OL-16 caused by a short between the finger contact pigtail and a bolt on the bus. Relays OL-17 and OL-18 were damaged and the holding coil circuit opened. This made it impossible to close the port motor starting contactors. The bolt shorting to the pigtail was longer than the rest. All bus joints in the vicinity of relays have been checked for overlap length bolts. Three damaged relay finger contacts were replaced from spares.

K.  MAJOR DEFECTS AND DAMAGE - Cont'd:
ENGINEERING DEPARTMENT - Cont'd:

On July 3, 1944 it was noted that the bow plane
tilting motor was running at excessive speed. Investigation
revealed that the plugging switch, shorting the resistor (CD)
in the shunt field circuit would not close. This provided the
motor with a weak shunt field permitting a high speed. The
worn plugging switch was replaced and operation returned to
normal.

A routine check revealed the solenoid operating
ing the stern plane clutch to be overheating. This was caused
by failure of the switch, short circuiting the resistor, to
open. As a result excessive current passed through the sol-
enoid. Adjustment to the switch operating mechanism correct-
ed the deficiency.

At 1221.9 hours # 9 unit on # 3 engine showed
an excessive exhaust temperature and a low compression press-
ure at slow speeds. The unit was disassembled and holes were
found through the faces on two exhaust valves. Erosions
were found on the seats of the other two.

During the patrol the following units were dis-
assembled after showing the same symptoms:

K. MAJOR DEFECTS AND DAMAGE - Cont'd:
ENGINEERING DEPARTMENT: - Cont'd:
This casualty appears similar to that experienced by the DACE on her second patrol. However, only a slight increase in exhaust smoke was noted prior to pulling the cylinder heads.

The day before leaving Brisbane, Australia an inspection revealed holes through the outboard side of the end pipes at the forward end of number 2 and 3 main engine mufflers. These were patched by welding. Early in the patrol number 4 muffler gave way in the same place. Three new mufflers will be requested at the next refit. No. 1 muffler was replaced at Brisbane.

ORDNANCE DEPARTMENT:
On June 17, 1944 all torpedo tubes were made ready for firing and remained flooded for a period of approximately twenty minutes, during which time the greatest keel depth was 65 feet. The tubes were not fired. After securing the tubes a routine check revealed that two torpedoes forward and one aft had flooded afterbodies. Further investigation indicated that all three torpedoes had flooded through the exhaust valves. In each case there were two or more' exhaust valves which had "holidays" in the tackiwax seal around the periphery of the valve where the tackiwax had either failed to adhere to the metal or which had been missed when applying the tackiwax.

No defective hand hole gaskets or other apparent cause of flooding were found.

L. RADIO.
Radio performance for this patrol has been satisfactory.

L. RADIO - Cont'd:

Following Bells serial numbers which were not retransmitted at night were missed:
   871 918 939 955
   902 924 943 956
   912 929 954

Task Force Strip Serial 12 and Serial 21 were missed. Believe Serial 21 was not transmitted due to fact no Bells numbers were missed between Serial 20 and Serial 22.

Were unable to contact any Australian Shore Station on 8470 kcs during night of June 30 - July 1. No faulty transmitter operation was observed; the antenna stage indicated maximum output. A shift to 4235 kcs resulted in immediate contact with Radio Perth and delivery of message with little difficulty.

In order to facilitate standing of split phone watches on assigned frequencies the positions of the RAK-6 and one of the RAL-6 were switched so that the output of both RAL-6 receivers is fed into the Control Unit, thus eliminating use of loud speaker. No intelligible signals have been observed on the submarine patrol frequency and no obvious attempts at jamming.

The very low Bells frequency has been of little value due to heavy atmospherics. Attempts have been made to read Bells schedules using the loop antenna while submerged but signals were barely perceptible due, perhaps, to the limited range of the loop adapter - 15 to 35 kcs.

Only moderate interference has been experienced during intermittent use of SD-4 radar; none from use of SJ-1 radar. Complete blocking of both RAL-6 receivers resulted from the radar approach by a plane during the night of 30 June.

M. RADAR - Cont'd:

The equipment failed to pick up land on 30 June that was apparently within its range. While submerged the following day the equipment was returned by means of the CW-60ABM Wavemeter and Echo Box. A new crystal converter was also installed at this time. After surfacing the following evening land was contacted at about sixty thousand yards. The equipment required only slight adjustment to bring this echo to its maximum height. Later the same evening land targets were picked up at around ninety thousand yards.

On 10 July interference was detected on the SJ-1 radar at position 05-06 N., 125-06 E., course 100 true. Bearing of first contact 160 true. Lost contact at 230 true. Interference appeared as railings, believed to be from other SJ-1 equipment of the U.S.S. CERO.

On 17 June while tracking target interference was seen on the "A" 'scope in the form of wide railings reaching to saturation. Source of interference was rotating at about 10 RPM. Position: 129-00 E., 07-22 N. Did not prevent use of our equipment. Source of interference believed to be enemy radar equipped escort.

The following interference was received on SJ-1 radar using a 706-AY magnetron:

On 28 June railings appeared on the "A" 'scope of this equipment. Position: 03-12 N., 127-35 E., bearing 075 true. Received over 90 degree sector. Rotation of antenna 6 RPM. Possible source: other SJ equipment from U.S.S. DARTER.

On 5 July railings were received on the "A" 'scope and shortly thereafter on the PPI 'scope. Position 05-15N., 124-37 E., bearing 090 true. Received over 90 degree sector. Rotation of antenna, 10 RPM. Appeared to be other SJ radar. Possibly U.S.S. CERO.

RADAR: - Cont'd:

On 5 July wide railings appeared on the "A" scope. These railings did not reach saturation and were much wider than the usual type of interference received from SJ equipment. The interference appeared on the screen for only short intervals making it impossible to obtain a bearing on its source. They were sometimes observed on bearings of 180 degrees difference which might have been due to back radiation of some rotating antenna. Position: 05-15 N., 124-37 E. Possibly enemy shore radar station or enemy escort vessel seen in vicinity earlier.

M.  RADAR - SN-2 REPORT - Cont'd:
The last cootat seemed to be SJ-1 radar.
The pulse rate was changed by varying the pulse rate of the SJ-1.
Two alterations were made to the SN-2. The first of which was a small audio amplifier and 10" speaker mounted to the case. Input to the amplifier was taken from the phone output and fed to the amplifier. The 110 volt supply was taken from the input terminals of the power pack to the amplifier. This alteration was made to facilitate standing w:r:ch on SN-2 while standing COC watch.
The second alteration was to install an antenna switching arrangement on the I.F.F. antenna. This was done by using a standard BN antenna transfer switch with solenoid switch. The ABK was connected to the side normally closed and the antenna to that side or the common connection. When the switch was operated the antenna is transferred to the SN-2. The 110 volt supply was taken from input to the power pack.
No break-downs were encountered during operation of the SN-2 equipment.

2. The material condition of the BASHW in general is very good and the state of cleanliness excellent. The number of exhaust valve failures on numbers 3 and 4 engines is considered excessive. An investigation will be made during the rofit period to determine the causes thereof.

3. BASHW will be given a normal two weeks refit by the U.S.S. EURYALE (AS22), at Scaddler Harbor, Manus.

4. The state of health of the personnel is excellent and their morale is high.

Tracked smoke into TAI TAI TAI anchorage.  Our position 10 miles south of entrance.  Should have seen masts or anything of any size.  No air covered, no escorts seen or heard.
2008 (I)  Surfaced.  Completed passage of SIBUTU.  Unable to pick out anything in TAI TAI anchorage.  Our time due on lifeguard station did not permit waiting here another day to see what this was.  Apparent lack of escort did not indicate valuable target.
2015 (I)  Strong signals on radar search receiver.  All-sensor interference on SJ.  Source of former appeared centered on BONGACO island; believed latter was HADDO.  See section M.  Headed north to PEARL BANK.  Low frequency radar signals faded out as we cleared.  BONGACO.  SJ interference stayed with us.

   Commenced tracking. Target determined as large AK with three escorts. Tracked at 14,000 to 15,000 yards. Maru and escorts plainly visible when against a clear background.
1200 (I) Posit: 07 - 07 N Miles: 280 Fuel: 3855 120 - 35 E

8 September 1944:

0100 (I) Base course initially 220° and worked around to about 200° during tracking and approach. Zigs were large and at 4 to 7 minute intervals. Two escorts on his port or low visibility side. One to starboard. None of the escorts were echo-ranging until after the ensuing attack.
0140 (I) Good target speed check at: 3 knots. Closed to 11,000 yards and submerged for periscope approach.
   During tracking and approach endeavored to keep target to the westward in order to have a clear background for periscope observations. This put two escorts on the attack side but accepted this as doubt that would have been able to see target against squally background to the east.

— page 101 —
8 September 1944 - Cont'd:

0225 (I) At 2500 yards able to see target well enough to get a good range. Target was a large modern AK. Unable to see port escorts against darker background. Sound and previous estimate of formation placed one fairly close aboard.

0227 (I) Commented firing six bow torpedoes, range 2200 yards, 50 - 60 port track, 150% divergent spread.

0228-35 (I) Torpedo hit. Run checked for # 2.
0228-42 (I) Torpedo hit. Run checked for # 3.
0228-50 (I) Torpedo hit. Run checked for # 4.

As was still unable to see port escorts after firing and sound had reported one speeding up, went deep and rigged for depth charge.

0232 (I) First depth charge. Strangely enough, the only one. Escorts commenced echo-ranging shortly after torpedoes hit. Evaded with no difficulty.

0235 (I) Began hearing characteristic breaking up noises. These were plainly heard both on sound gear and through the hull and continued for about 15 minutes.

0250 (I) Only one escort searching now and he doesn't have contact. Under the visibility conditions existing at the time of firing it is quite possible that torpedo wakes were not sighted even though they were steam torpedoes. This may have been a contributing factor to the ineffective search.

Other two escorts are either stopped and listening or are picking up survivors. Believe this ship sank within a half hour.

0455 (I) Echo-ranging very faint and only occasionally. Surface. Put in a quick charge, reloaded and returned to scene of firing. No radar contacts before we dove.

0559 (I) Submerged. Conducted search of firing area during day. Had all three escorts of last night in sight during the morning. Closed each to about 4000 yards and then avoided. All were now echo-ranging and searching the area. Two departed about 1000. The other stayed all day. AK of last-night is missing. No doubt that he sank.

1945 (I) Surface and headed into MINDANAO SEA for life-guard duty tomorrow. One PC still in sight and searching, shortly before dark.

0848 (I) Sighted single aircraft flying at about 50 feet altitude, distant two or three miles and headed down our throats with at 00 angle. He had come in with a land background plus low squalls. Could not identify immediately. (Plane contact # 32). Made record dive. Had VHF manned at the time trying unsuccessfully to establish communication with own air force and particularly own fire cover which had been theoretical thus far.
1048 (I) Friend or foe this was decidedly a most unfriendly approach. Could not pick him up in periscope after diving and saw neither he nor any other plane for next two hours. Atmos-phere appeared definitely hostile at the moment. Sighted air strike over CAGAYEN. Surfaced and proceeded in toward CAGAYEN LIGHT. Renewed attempts to establish communication. Large columns of black smoke from vicinity of docks at CAGAYEN. Many planes on hand. BASILAW had third row center seats for the show. Sighted small ship standing out of harbor. Thought at first he was a large patrol craft. Later turned out to be a small in-ter-island supply ship.
1106 (I) Finally managed to contact with strike comm-ander via VHF. Informed him that fighter cover would be appreciated. Spemwhat non-plussed and slightly irritated when answer came back, "why, are you being attacked?" This little matter quickly smoothed itself out, however, and four very efficient and business like F6F's appeared overhead in something less than four minutes.
1120 (I) Small ship continued out of harbor. Fight-er cover asked if we would like to have it strafed. As no rescue work had appeared yet, decided lifeguard unit might as well join in the day's festivities. Gave assent and closed for attack.

9 September 1944 - Cont'd:

Fighters delivered a very effective strafing job. Manned 4" and followed up with a gun attack. Strafing started fires. Saw crew of vessel abandoning ship. Three H.C. four inch hits disintegrated superstructure and amidships hull section and made a blazing fire of the rest.

Fighter cow. enjoyed this diversion so much that they frolicked off in search of more targets.

Ceased fire when apparent that ship was destroyed and con in towed reference point. When he seen ship had burned down to hull strakes, had a foot of freeboard and was sinking. Did not see any sign of it during three more days spent in immediate vicinity.

Air strike departed. Communication with strike says no rescue. Well into harbor now. As BASILAW air superiority appeared to be rapidly suspended submerged to await next strike.

Sighted next course coming in. Surfaced and established contact. Still no business for us.

Sighted small boat. Closed to investigate. Found boat about to sink and containing one wounded Filipino. Took Felomino Carpez of Cebu City aboard, who though suffering from three .50 caliber bullet wounds was still able to vehemently voice his nationality, his pleasure at seeing us, and his intense dislike for all Nips.

Very capable and efficient medical treatment of these injuries by Ensign R. C. SWAN, jr., U.S. N. R. and SHIPMAN, Bill (N), 356 60 79, PhMlc, U.S.N., prevented serious complications.

Continued surface patrol of MACAJALAR BAY. Gathered from conversation on VHF that last strike today would be about 1500.

K.  MAJOR DEFECTS AND DAMAGE - Cont'd:

In an attempt to reduce the smoke of that engine, expanders (G.M. Part # 3242268) were installed behind the oil control rings already in the engine. Since this alteration oil consumption has been reduced and smoking has been eliminated on both engines.

After 1,185 hours the coils on # 2 Evaporator began to leak. The complete set was replaced by the USS ORION on 28 August 1944.

BOW PLANE FILURE

On September 16th tilting power was lost on the bow planes during an all day dive. When the bowplanes moved his controller the contacts in the panel closed but immediately opened, as the control circuit was opening for no apparent reason. Continuity checks revealed an open in a 750 ohm resistor (item # 156). This resistor is placed in the control circuit when the brake release contact is closed by men on spring contacts actuated by the contact arm. The resistor was replaced from spares. At the same time a low reading was found on the shunt coil for control circuit contactor # 369. This coil was also replaced.

IC POWER FILURE:

At 0025 on 22 September smoke was discovered coming from the IC motor-generator switch panel in the pump room. This panel on commissioning consisted of two toggle switches controlling the supply for the two IC motor-generators. After the first patrol the toggle switches were replaced by 100 Ampere double pole switch. A dive was made to facilitate repairs. The IC motor-generators were secured and Emergency AC current was taken from the SJ motor-generator. Investigation revealed that the busses behind the panel were loose. A stud holding one clip for the # 1 switch was sheared off. All bolts were loose. The heat generated by the improper connections had started to burn the insulation from the main feeder leads. All panel bolts were tightened and the feeder cable was reinstated. Operation was then returned to normal. The panel will be rebuilt during the coming refit.

Wa. Patrol.

L. RADIO.

Reception of scheduled messages during the operating periods of August and September has been excellent and no serially numbered messages were missed, and no Bells Station numbers or other than those sent only during times when this vessel was not on the surface. The missing numbers are:

| Date       | Number |
|||
| August 908 | 976    |
| September 974 | 808    |
|            | 813    |
|            | 852    |

Recent attempts to communicate with air-ligible results while good, to poor results were obtained on VHF. The high degree of selectivity on the R/T type of receiver prevents accurate reception of voice.

Recent observations during a period of considerable radio activity on 2880 kcs point to the weakness of the R/L receiver for voice reception as well as to its excellence for W/T signals. This vessel was able to make an accurate copy of several messages sent by W/T while fragments only of messages sent by R/T were possible from submarines operating at a distance of about 1500 miles.

Due to the increase in the use of voice modulation with tactical operations it is suggested that once superheterodyne receiver with a range of 2000 to 5000 kcs be installed in all submarines.

M. RADAR.

SJ-1 RADAR:

This radar gave very reliable operation during the patrol. There were no major breakdowns and only about five hours of operation were lost. Much credit is due to CLIDWELL, Richard W., 633 54 25, RTLC(T), (SS), U.S.N.R. and the entire gang of R/T's for their continuous and diligent efforts to keep this equipment in tip-top shape. There were some tube failures, notably 504G's in the low voltage rectifiers. Once when the equipment was placed in operation the magnetron blower failed to start. Fortunately, this was noticed before any damage

was done. The blower and motor were removed from the transmitter, cleaned and adjusted. When the unit was reinstalled it appeared to run faster and provide more air. The transmitter of this equipment is protected by a sheet metal cover. This shield covered the louvers on the side of the case and prevented free circulation of air. The shield was removed and cut in such a manner as to provide better cooling. It is believed that excessive heat inside the transmitter caused either the magnetron or local oscillator to drift in frequency and detune the equipment. It was necessary to install a new gain control in the indicator unit while on station; the one that was removed had opened due to wear.

Fair to good ranges were obtained with this equipment. Land echoes were received to the end of the main sweep and an unidentified ship target was contacted at 26,000 yards. There were several aircraft contacts made - one at 34,000 yards.

SD-4 EQUIPMENT:

This equipment operated very well and required only minor adjustments. However, near the end of the patrol it was necessary to install a new set of 8014A's. In most instances aircraft was contacted by this equipment before being sent by the lookouts. While on station the SD-4 radar was used only five or ten seconds out of each minute during good visibility and the remainder of the time on the surface it was left on stand-by to be used in the event of a contact on the SN-2 intercept receiver.

During life-guard operations the SD-4 had to be secured when using the VHF for voice transmission. As both units operate on the same antenna. As the need for the SD is as great if not greater during these operations the installation of a separate antenna for the VHF appears necessary.

INTERFERENCE ENCOUNTERED:

Interference from other SJ-1 radars was seen on several occasions. However, it was never of such an amplitude to cause interference with normal operation.

V. RUMORS:

Lifeguard procedure went well once we got started. As the key to successful coordination with air strikes is satisfactory communication with the strike, all effort should be made to improve the VHF equipment. It is believed that a separate antenna would increase its efficiency.

Had no fighter cover unless asked for. Had no trouble getting it then, however. Advance intentions to the lifeguard submarine of the scheduled times of strikes each day would be of benefit in carrying out this duty. The question of security of the operation naturally arises here but believe it could be done with no great risk.

L. RADIO: Cont'd:
(1) a falty master oscillator switch;
(2) inexperience as to the effect of atmospheric conditions and long distance transmission and reception encountered in our patrol area; and
(3) a certain amount of poor cooperation from shore stations. Having no make repeated calls so allows added time for the enemy to begin jamming. Yet a contact report cannot be sent out "blind" in hopes that someone will receive it later. There is no reason to believe that our transmitter was off frequency because it was zero beat against our LR-1 frequency meter before each transmission. The frequency meter was checked with NPM and Bell Connen.

6. VHF communications between submarines attempted while on station. This method of communication seemed quite good during training exercises but on station transmission and reception were not both possible on the same channel. It is possible that the automatic transponder may have slipped on its shaft, or poor at-mosher conditions may have been solely responsible. The tuning will be checked during refit.

Although a separate antenna was installed for VHF during the last refit, communications could not be conducted while the SD radar was operating due to interference from that source. It appears that the VHF frequencies are too close to the SD radar frequency for the selectivity of the receiver.

M. RADAR:
SJ - 1:
1. Operation of the SJ-1 radar was satis-factory during the patrol. Only one major breakdown occurred while on station. The equipment was out of commission for about two hours at this time. Ranges obtained were good on both land and ship targets. Submarines were usually contacted between eight and ten thousand yards and land echos were received to the limit of the main sweep on the "A" scope.

While the "steerable sweep" aids in searching since taking ranges causes loss of the target on the "PI. It is suggested that at 20,000 yard sweep be greatly aid in attacking or tracking targets at ranges from 8000 to 20,000 yards. With the present 40,000 yard scale resolution of several targets and tracking is difficult at ranges around 10,000 yards. It is believed that this alteration could be accomplished simply by connecting a .23 megohm resistor between the plate of the san toot generator V(1)2, and a .176 megohm resistor between a similar spare contact on range selector switch S(1)B and the grid (terminal 1) of the square wave multivibrator V(1).1.

2. It is suggested that some other means of keying the radar transmitter other than primary keying of the high voltage power supply be used. Some methods of blocking the modulator, V9, might be employed. While this might necessitate a more elaborate initial installation it would result in fewer breakdowns of the high voltage system. No spare high voltage transformer is carried in the equipment spares.

SD - 4:

1. Operation of the SD radar has been fair during the patrol. This equipment was operated for the most part only five or ten seconds out of each minute for searching. The radiation keying switch installed during the last refit has greatly facilitated this type of operation. On several occasions aircraft were detected by lookouts at ranges within that of the SD.

This was either due to nulls in the radiation pattern or to a possibility that the R.F. generator was oscillating at two different frequencies since good ranges were obtained at other times. Frequency checks and constant plate current seemed to indicate that the

This was the last instance when we were able to secure the transmitter because we had no more results. The trouble was corrected during the next sub-ship's return by installing a new transmitter and not allowing the submarine to return to the C-60 class.

While certain, on 22 November the primary C-60 was in the hull, it was available at the C-60's crew's discretion. The radio station was in the control tower was directed and visible in the ship's view. The C-60 was in the control tower was

2. It is assumed that some other means
of keying the radar transmitters other than primary key-
ing on the high voltage power supply to use. Some meth-
ods of locking the modulator, V9, might be employed.
While this might necessitate more elaborate initial in-
stallation it would result in fewer breakdowns of the high

ried in the equipment stores.

by lookouts at ranges within the vicinity of the 3D.

This was either due to nulls in the radio-

range were obtained at other times. Frequency checks
and constant plate current seemed to indicate the 3D the

TENTATIVE CONDUCTED:

The 37-1 was used to collect extensively for
with various success. Reception by enemy ships was so weak
that reception was obtained visually from within the
small airlock but it has not yet received satisfactory
because it decreased the signal to noise ratio too much.
Communication seemed to improve with the use of the
stereo as the quartermasters in the watch became more ex-
perienced at radio. The success of visual communication
was caused by a mixture of visual and radio communica-
tion procedure. It is strongly suggested that visual pro-
cedure be adopted. This may be slower
than the radio procedure and is consistent
with the experience of the submarine
in 7000 yards and was first reported by a destroyer
in 7000 yards. The radio procedure was so ab-

The general situation in the 3R-2 during the
entire patrol has been successful. No major breakdowns occured during the patrol. During the 1-irst week at sea the
set became unusually noisy. This was remedied by replacing the 955 oscillators.

In refit the 3A-1 pulse analyser was installed to be used in conjunction with the 3-2. The 3A-1 gave satisfactory operation during the majority of the patrol.

On 22 December a short overshoot in the cathode ray tube of the 3A-1 causing the bleeder resistor R201 to short cut. This short arc caused a distortion trace on the scope and the lines in the line.

The operation of the 3A-1 with the 3L-2 is a great help in reconnaissance contacts and determining the types of contact. The addition of the 3A-1 definitely makes the 3L-2 easier to operate. It also makes the 3L-2 more sensitive when time to a definite contact.

Twice during the patrol a contact on the 3X-2 was reported which was analyzed as rain. The pulse rate varied from 500 to 1000 and the signal increased in intensity as the rain increased.

U.S.S. BASHW (SS 241) - Report of Fourth War Patrol.

1. This fourth patrol of the U.S.S. BASHW was the first under operational control of this task force. BASHW formed a unit of a coordinated search and attack group commanded by the Commanding Officer of the U.S.S. FLOUNDER (SS251). The patrol was conducted between Dangerous Ground and the Indo-China coast.

2. One torpedo attack was made. This was a day periscope attack on a two ship convoy east of TIZARD BANK in Dangerous Ground, on 21 November 1944. Four torpedoes were fired at a medium freighter, range 3100 yards, eight foot depth setting 1100 track. At least one of the torpedoes ran erratic forcing the BASHAW deep before results could be observed. One torpedo hit was heard, timed to be a hit in a medium tanker overlepping the stern of the freighter. A depth charge attack prevented further observation. A full salvo of six torpedoes would have given better chance of success in the attack.

3. A burning ship was sighted that night upon surfacing. The Commanding Officer considered that the ship was a total loss and would probably sink before morning; therefore he continued his search for the original convoy. We know that the enemy has shown remarkable ingenuity in getting cripples in to port and it is believed that expenditure of torpedoes was warranted even if light conditions dictated a submerged attack. However the Squadron Commander was not there and the judgment of the Commanding Officer has always been beyond reproach.

4. The BASHW rendered invulnerable service on 14 December 1944 in sighting and making contact report on a strong enemy task force. This was the first report of this force and the contact report had far-reaching results. Attack could not be made, the minimum range attained being 7950 yards.

5. The transit of Lombok Strait was made submerged. Three petroleums were encountered. They conducted a search, probably based on information from shore reader.

6. The BASHAT returned from patrol in good material condition. A normal refit by U.S.S. SURYALE (AS22) and Submarine Division 182 relief crew will be conducted. The report on material, particularly electronic gear, is very complete.

7. The state of cleanliness upon return was truly excellent. The morale and health of the crew was high in spite of the fact that this was a sixty-six day patrol.

8. The Squadron Commander welcomes the BASHAT back into the fold and congratulates the Commanding Officer, officers, and crew upon the damage inflicted on the enemy.

2. On 21 November BASHAW made her only attack when she fired at one AK in a formation of two MARUS, and timed a hit in the other ship, an AO. That evening BASHAW made contact with a stopped and burning ship at 2232 which was considered a total loss and further expenditure of torpedoes not warranted.

3. On 16 December, in position (06-05N 108-01E), BASHAW sighted the floating bow of a bunker ship whose stern was apparently firmly anchored to the bottom. Two torpedoes were fired and both missed.

4. The award of the Submarine Combat Insignia is not authorized for this patrol.

REASSESSMENT OF DAMAGE BY SUBMARINES

Reference: (a) ComSubPac 1tr. FF12-10/L11(1) of 21 February 1946.

USS BASHAW (SS241) 4th War Patrol
Date of Attack: 21 November 1944
Position: East of TIZZARD BANK

BASAW, on her 4th Patrol, was part of a coordinated attack group consisting of herself, FLOUNDER and GUAVINA. At 1727 on 21 November 1944 BASAW fired four torpedoes at the leading AK of a two ship, escorted convoy. One hit and a series of muffled explosions, were heard but not observed due to BASAW having to go deep because of an erratic torpedo. Later FLOUNDER fired a spread of six bow tubes at the same convoy (composition same as when sighted by BASAW) for three unobserved timed hits. FLOUNDER was forced deep by escort. DNI lists and Japanese verification state that the GYOSAN MARU of 5,698 tons was the ship attacked at this time and DNI credits the sinking to FLOUNDER. A study of the patrol reports indicates that the GYOSAN MARU was sunk as a result of BASAW attack and probably three from FLOUNDER. According to the papers BASAW should now be credited with 2,849 tons sunk in this patrol (1/2 of GYOSAN MARU, shared with FLOUNDER) and her 4th patrol declared "successful for purposes of submarine combat insignia." Commanding Officer, Cdr. R. E. Nichols, U.S. Navy.

2054 (H) Fired stern tubes; (Torpedo attack #1). Three l.h. 18 torpedoes at second target which appeared to be a 250 ton sea truck and one l.h. 18 at the leading target which appeared somewhat smaller. Torpedoes were set or 2 feet, fired down the sea, sea about force three; torpedo run 1500 yards. The first three torpedoes broached about 50 yards astern and then appeared to jump from the fourth and were all the way to the target. The fourth torpedo broached about 10 yards astern and was not definitely seen again, although the Commanding Officer thought he saw it on the port beam a few seconds later.

2057 (H) One hit on larger target seen and heard from bridge (below decks personnel reported two hits). Target sank almost immediately. Just prior to firing visibility improved somewhat so that targets could have been seen through gun sights at a range of 900 - 1100 yards. Considered shifting to gun action but in spite of size of targets decided to continue torpedo approach for several reasons; among them the fact that in the 18 months we have been in commission have never fired a MK 18 war shot and have never fired a war shot from the airt room.

2106 (H) Commenced approach and opened fire at 1100 yards. (Hur accuracy 1). Four inch gun failed to fire, the forward 20 MM jammed with a ruptured cartridge case. After 10 rounds had been fired and the after 20 MM would not train far enough forward to bear on the target. Target turned toward us and emerged to close. Continued run, closing to 600 yards, and asked the target with 1000 rounds of 30 caliber from M.G.'s. Target observed to stop and small fires started in superstructure. FLASHER followed 500 yards astern of us and made two nice runs, getting many hits with her four inch. BASHAW made second run firing 30 caliber and 20 MM, during which time the target rolled over and sank.

2210 (H) Received message from FLASHER that she was searching wreckage of gun victim for survivors. Headed back toward point of torpedo attack.

2245 (H) Sighted more than 50 sail drums in the water and much wreckage. Received message from FLASHER that she had two prisoners.

1632 (H) Commenced firing at escort. (Torpedo attack #2). Gyro attack from 172 to 162, torpedo run 1000 yards, track mile 115 - 125 port. As third torpedo was fired observed escort two-block two large red flags at each yard arm, a large blaze of steam came out of his whistle and a large column of smoke out of his stack. He spun on a dive and started toward us. First three torpedoes missed ahead. Escort either saw pursuers on observation before firing ('scope up less than fifteen seconds) or heard fish start run. Checked fire.

1636 (H) Obtained new set up. Gyro angle 178, angle on the bow about 3 - 5 starboard, range 750 yards, torpedo run about 40 yards; and fired "down the throat shot. Since he already knew where we were, should never changed depth setting to zero or two feet. Not torpedo broad, but this was an extremely.

1637 (H) Torpedo missed or passed under. Went deep to 150 feet - 180 feet depth here - and stuffed cotton in our ears. Escort's first run was pretty good, passing over our stern; but no depth charge was dropped and there was no evidence of contact charges. He got progressively worse and further away. At

0758 (H) Lookout sighted plane on our starboard quarter, range about 5 miles. (Aircraft Contact # 27). Submerged to avoid detection. Decided to close targets submerged.

0924 (H) Identified targets as 4 sea-trucks in column. The leading one was about 150 tons with what appeared to be a large M.G. mounted on the poop deck. The next two were lugger-type, about 75 - 100 tons. The last one was exact duplicat of FUJI MARU Sugar-Charlie sea-truck, 273 tons, with one M.G. in evidence on top of deck house.

0940 (H) Surfaed and approached targets from port quarter. Opened fire at 2400 yards on largest target. Observed 4 hits, two of which demolished dock house but did not set target afire. The target uncer fire speeded up, and on parallel courses we passed the others at about 10 knots. The two laggers did not change course but the leadig sea-truck turned stern toward us. As we passed the leading one, shifted fire to him and scored two 4 inch hits which started him smoking.

1000 (H) The original target closed us to 1800 yards and opened fire with small M.G. Very inaccurate at that range but it seemed as though there were a lot of bullets flying around the gun crew and the bridge. Shifted fire to the original target and obtained one additional hit amidships. M.G. fire stopped.

It became evident that the starboard board was to carry out original plan would give us absolutely large track angle.

1006 (H) Swung hard right at flank speed to cut in a head of escorts, stopped to kill headway, and when pit log read 12 knots fired six torpedoes forward, depth set 6 feet, torpedo run 3700 - 3300 yards, 210 starboard track angle, 0 gyro angle, 220 % divergent spread, estimating target's length to be 400 feet. (Torpedo attack # 4). As last torpedo went out, shifted redark back to escort who was 1490 yards on our port beam. Went ahead flank and turned to open out, expecting him to pop out of the fog at any minute.

1009 (H) Two very loud and solid-sounding explosions 8 seconds apart, timed for # 5 and # 6, followed 29 seconds later by a more muffled explosion. Hoped that we had been lucky enough to get a hit in one of the far escorts but never saw anything to substantiate this wishful thinking.

1015 (H) Heard no depth charges, but it was evident that the escort was following down torpedo tracks and probably our wake. Range 2,000 yards, opening slowly, and we are making over 19 knots. Target tracked as stopped.

Considered making a submerged approach on the escorts out decided clearance of success would be better when they had settled down on a definite course and speed. If they waited long enough before leaving, good chance for a night surface attack.

2003 (H) Fired # 6 tune - HMM. Target seemed to settle somewhat, smoke slightly and nothing else. Decided that we were best we could do. APR contact 150 a.m. 6:00 H.M., saturation strength, but weakening.

Handed back to vessel area.

2030 (H) At 7,000 yards, pi suddenly disappeared from radar screen. Returned to firing point and found that wreck had disappeared.

Final verdict: SHK: one large tanker. The estimate of tanker is based on the sight-ing by the BLOWER. The estimate of "large" is based on the size of the radar pip, the fact that target was making 14 knots, and the fact that target was at least 450 feet long.

Patrolling NE of CAPE TOURANE. Decided to stay 12-15 miles off shore and patrol on surface.
0849 (H) Slighted small ship from bridge, (Ship contact # 8), coming from direction of yesterday's firing. No radar contact. Started tracking.
0900 (H) Target tracks at about 6 knots, headed for TOURANE.
0907 (H) Submerged on track to look him over.
1000 (H) Target is small sea-truck (100 tons). Planned to let him open out and then battle surface.
1030 (H) Second sea-truck sighted, about 6 miles as-
tern of the first. This second one was much larger, Sugar-Charlie type, about 250 tons, with two life-boats on deck house, and one M.G. visible.
1106 (H) Let him go by and surfaced astern. Had under estimated his size and range was 7200 yards when I expected it to be about 4000 yards.
Manned the 4 inch gun and closed on four engines.
1125 (H) Opened fire when range was about 3800 yards. (Gun attack # 4). Target kept stern toward us and maneuvered radically. Only three hits

1125 (H) Cont'd: - In first 20 rounds. After range had closed to 200 yards, began hitting 4 out of 5 times. Continued to close range until 900 yards, at which time target sank.

1152 (H) Closed wreckage on deck over 50 Japs in the water, some were clinging to half-submerged rafts, some were clinging to debris, but most were just swimming around. Almost all had on life-belts that resembled water-wings; all wore very new, iron helmets uniformed (trousers and jackets) and all had on caps with the Jap Navy insignia.

1155 (H) Maneuvered to try to get one aboard. The "whole" ones would have no part of it and turned their backs whenever the boat came alongside. "Briefly" to encourage them with a few rounds from the "stray gun", inadvertently snatches of the ship's radio and refused to cooperate.

1200 (H) Several on a raft indicated they would like to come aboard. "We" (or "we" or "we") agreed to try to get aboard. We will probably have to wait for the other boats to come aboard. We will probably have to wait for the

    C.  PRINCIPAL:
    During the month of February, the weather
    LAND was constantly overcast and rain was
    squalls and low clouds. The wind and sea were
    from the north. The sea was a moderate force of about
    six (Beaufort Scale).

B.  TWILIGHT:
    A coast was set to the south was ex-
    perienced off the east and north east coast of HAINA
    ISLAND with an overcast velocity of from .5 to 1.5
    knots varying with the strength of the wind and sea.
    During the early part of the night a slight set to the
    south east was observed on the TOWARTH BAY, but the cur-
    rent was never greater than .5 knots.

E.  NAVIGATIONAL AIDS:
    No navigational aids were observed. Due
    to consistently overcast weather all navigation while
    on station was by means of radar fixes on land.

    during the approach, gradually closing to 500
    yards and occasionally opening to 4000 yards.  0800
    Target group appeared to be a large ship with four
    escorts.  Tracked targets at 1,000 - 14,000 yards
    on course 035 true, speed 10, not zigzagging.
    Dove twice at 0806 and 0825 for SJ contact (air-
    craft) closing on a steady bearing to 3 miles.
    0832  Surfaced and resumed tracking.  Had inter-
    mittent SJ contact on aircraft which appeared to
    be circling convoy.  0845  Pilot showed 3 escorts
    in column on port side of target.  With target
    bearing 184 true, range 1,000 yards, AOB 30
    port, commenced working ahead to attack from star-
    board side.  0945  Contained 4th escort on targets
    starboard bow.  Planned to fire system of starboard
    escort on 90 - 100 seconds - track but as firing
    point was approached the escort dropped back to
    target's starboard quarter, raising it necessary to
    fire ahead of escort who was bearing 280 relati-
    v&.  Firing range was 370 yards, torpedo run
    3850 - 3200 yards.

DAMAGED DETERMINED BY: Two 1- and 6-inch explosions were heard
    throughout the ship's time for hits by # 5 and # 6
    torpedoes.  This was followed by a muffled explo-
    sion 29 seconds later.  Radar pip decreased in
    size until lost at 16,000 yards.  Target tracked
    as stopped.  At 1200 observed 80 to 100 feet of

J. ANTI-SUBMARINE MEASURES AND EVASIVE TACTICS.

Anti-submarine measures can best be described as encouraging. Lost of this patrol was spent on the surface and aircraft contacts were fairly numerous. None of them got in position for a very good run, but it seemed to me they passed up one or two fair opportunities to shake us up.

Seven different escort vessels were seen, and all were practically identical. The superstructure was bulkier than that of a torpedo boat, square bridge, one gun forward, dislocated on a partial turret, two or three similar guns aft. The forward gun was very close to the bridge structure. This type had broken decks with slender stack, slightly raked, just aft of bridge structure.

Foremost was 85 to 95 feet high with what could have been a radar at the top. (Not horn type). Maximum was small stick type with cross arm, much smaller than on the Jap Patrols. Have never seen anything exactly like these before, and they dont correspond with any of our pictures or silhouettes. Probably a version of the Jap D2 UN-1 or UN-2. Maximum speed, about 17 to 18 knots. The one encountered on February 25 was echo-ranging on 18.2 kts. The

I. RADAR: - Cont'd:

By over six thousand yards. After the equipment had been in operation for about a year the crystal current again dropped and the tube fell off. A new crystal was installed and the results were again obtained. During the mid twenties the tube developed out of commission for any reason other than the trouble was temporarily cut off by installing a new crystal. At this writing the crystal has been in operation about fifteen hours and is still satisfactory. It is believed that the trouble is due to the TR cavity. If the present crystal fails the TR system will be thrown. The new crystal current is adjusted to the new crystal. On February 28 it was necessary to replace the first IF tube in the range indicator so bring the grass up to optimum operating level.

During the last refit period several field changes were made on this equipment. The increased signal overload modification has greatly improved the operation by making weak lips much easier to see. The addition of a twenty sonar range sweep on the PFI was very helpful. Most of the radar approaches were made using this sweep. Changing the position of the audio output in the cables resulted in a 330 ohm cable for ground. The cable of 77 (2200 ohms a-bove ground) greatly increased the strength of the communications signals received. With the 330 ohm tap the signals could often be read visually from the "A" scope before they were even heard in the phones. It is believed that this change in range of the equipment is caused the communication The OBU echo box was a great aid in checking the receiver tuning in the absence of the jocks; however, the 60AHM is still preferred for tuner the transmitter.

SD-4 EQUIPMENT: - Fair results were obtained from the SD-4 radar. Ranges varied from six to twenty four miles. However, the 5J was more reliable in picking up aircraft than the SD. The only material replacements were one RF tube (the first) and the port whip of the antenna. No explanation can be given for the breaking of this whip. The break occurred

REMARKS: Due to the shallowness of the water at location of contacts 2 to 5, echo ranging contacts were made at relatively short ranges (about 15,000 yards). Maximum range obtained on escort screw contacts was 7,000 yards.

An attempt to take a ping range on the escort, contact # 2, failed (periscope range at the time 1,200 yards. During the second approach on the target group a ping range of 2000 yards was obtained on a small AK.

Due to the shallow water in which this patrol was conducted no bathyphotographic data was obtained.

P.  HEALTH, FOOD AND HABITABILITY

General health was excellent. No cases of illness or injury occurred.

The food, although well prepared, was not as varied as on previous patrols. This condition was largely due to the lack of variety of meats and canned vegetables which were available at the N.S.D., Freemantle, W.A. or from the U.S.S. SURYALER.

U. K.DIO AND RADAR COUNTERMEASURES: - Cont'd:

Due to the fact that the APR-1 is much more sensitive than the SH-2 some difficulty was encountered during the beginning of the patrol in distinguishing between ship noise and the actual radar contacts. After studying literature carried or expenses frequencies and pulse rates and identifying ship noises by the use of the SPE-1 and a new version of the antenna. The APR-1 proved very valuable, as warning devices. The receiver was used whenever the SH-4 was not in operation which made for almost 24 hour operation.

Noise was encountered on 15th mes and 278 mes from radiation from the SH-1 radar. Interference occurs at 200 mes and 300 mes when the SH-1 is being keyed.

On February 5th a very peculiar electrical interference occurred. This interference was a very strong strength, steady signal, with a pulse rate varying from 30 - 60 and with no trace width. This occurred strongest at frequencies between 125 and 150 mes. This interference was also causing the SD-4 receiver to be blocked so that no contact could be recognized. It was determined by the use of the pulser circuit in the SD-4 that this interference came from an outside source. It is suggested that this might have been some systematic jamming.

Numerous times during the patrol the APR-1 gave warning of aircraft soon 12 minutes before aircraft was sighted or contact was made by radar. The SD-4 had two contacts at 22. The pulse two minutes before any APR-1 contact on a second. Several times we attempted to check the APRO-1 radar direction from which interference came by switching ship and utilizing the directional features of the APR antenna. This was a complete failure.

There were no major breakdown of equipment. On the third week of the patrol the noise level seemed to decrease with maximum gain and increase with lowered gain. Trouble was traced to the A.V.C. circuit.

Subject:
U.S.S. BASHI (C-1) - Report of Fifth War Patrol.

1. The BASHI's first patrol was of 47 days duration, H.S. Simpson, USNR, was in command. Lieutenant Commander as Commanding Officer.

2. BASHI made 5 torpedo attacks on three of five contacts which the commanding officer acknowledged partly of torpedoes; in addition, four gun attacks were made, two of which were in joint action with FLASHER.

3. Two contacts that were not developed into attacks were a radar contact on 2 unidentified ships. On the first BASHI was unable to close due to radiol. signals of force; one of the BASHI fired a large calibre shell at BASHI which landed 2000 yards short. On the second of the contacts the two unidentified ships were tracked into Taurano Bay precluding attacks.

4. Torpedo attacks:

Attack No. 1: In night surface attack 4 mark 16's set at 2 foot range fired; 3 more fired at 25 and 35 mark 16's set at 2 foot range. One hit was made in the 30 which disintegrated.

Attack No. 2: The contact was conducted of one small AK with one DE as escort. During approach attack 4 mark 16's set at 4 foot range fired at 1000 yards. DE evaded torpedoes and headed for BASHI. Five minutes later 1 mark 16's set at 4 foot range fired in a depth-charge attack at DE with a torpedo run of 450 yards. Torpedo raised, possibly running under.

Attack No. 3: This attack was made in the 30 in convoy of attack No. 2 after an on-ground contact of report was given to FLASHER. In a night submarine patrol attack, 4 mark 16's were fired range 2000 yards. Target sighted radiol. by between 2/3 of third and fourth torpedoes; all missed. Two depth charges were dropped, no damage suffered. BASHI saw two or three explosive flashes in direction of AK and later received report from FLASHER that she sank to 2.

20,000 yards, at which time it was a saturation
pip.  Then began to decrease in size.
200 (H)  Closed to 3,000 yards and identified target as
sail boat.
There has been some theory advanced that these
sail boats have radar reflectors and act as
decoys for enemy submarines.  I think this is
highly improbable.  In this area we noticed
this same radar phenomenon of remarkable ranges
every night from about mid-night to 0200.

K.  MAJOR DEFECTS AND DAMAGE:
ENGINEERING DEPT.: #2 EVAPORATOR: - On April 12th silver nitrate tests indicated salt water in the distillate of #2 Evaporator. Total coil heat is this time were 1281.8. Hours since cleaning and washing were 148. The unit was disassembled and pin holes were discovered in coils two and six. Coils five and six were so jammed together that they could not be separated. The holes were silver-soldered and the evaporator reassembled. Operation was normal and no further indications of salt water were noted.

#2 LOW PRESSURE BLOWER: - After surfacing on April 4th excessive/sparking was noticed at the commutator of the blower motor. The motor was immediately secured. The inspection plates were pulled, the commutator cleaned and checked for high mica. A bar to bar check was made and two coils were discovered shorted together. This was traced to some loose solder between two coil connections at the risers. The connections were also loose. These were cleaned, resoldered, and coated with glycol. Operation returned to normal.

ORDNANCE DEPT.: A full voltage ground was discovered on one electric torpedo, Mk 18-1, register # 57076, battery serial # 1793 during the first battery charge of the torpedo after its receipt on board from the USS ANTHEDON, 26 March 1945. After following the normal preliminary procedure, this torpedo was put on charge at the 7 amp rate. After one hour of charge a full voltage ground was detected in the charging panel and traced to a section

K.  MAJOR DEFECTS AND DAMAGE: - ORDNANCE: Cont'd:

of the battery positive lead and charging plug lead between the battery compartment after bulkhead and the connection of the leads to the #6 field pole. At one point, the triped insulation on the leads was worn and wet and touching one of the bulkhead ribs. After cleaning thoroughly, the lead was retaped; the ground eliminated.

L.  RADIO:

Only one missing serial - #56 - during last three days of March. None since.

Bakers frequencies 4370 useless in patrol area. Heard only during early morning hours - too much static and interference to be read.

9250 kcs. best frequency for most of day and night but has heavy interference during first evening schedule - usually occurs up by 1330 GCT - stays clear until 1630 GCT when voice transmission renders it unreliable for about an hour.

12630 kcs. very good during most of day and night. Usually fades during mid-day and after midnight for two to three hour periods.

1617.0 kcs. very useful during early morning and afternoon.

Wopaco frequencies - Most subs use preliminary call up - sometimes losing as much as 30 minutes in calling in violation of order. Procedure bad. These frequencies are very noisy - both static and other transmitters but are suitable for close range work.

VHF operation has been unsatisfactory in more than 3000 yards away. Reception ranges seem normal. Apparently fault lies in our transmitter. Unable to determine trouble.

No major casualties to either transmitter or receiving equipment. Receiver protective relay operation unsatisfactory.

L. RADIO: - Cont'd:

The transmitter blower motor failed. Since frequency stability unaffected did not attempt repairs because surface operation made inadvisable to place transmitter in necessary inoperative and unstable condition.

M. RADAR: - SJ-1 - Operation:

The operation of the SJ-1 radar was satisfactory and reliable during the SIXTH war patrol. The equipment was used extensively for navigation as well as for normal searching.

Land ranges from forty two thousand yards on a six hundred foot island up to one hundred thousand yards on higher land were obtained. Second sweep land echoes were seen almost constantly while operating off Hainan, Indo-China and the China Coast. In addition to the normal second sweep echoes which appear fuzzy and narrow in bearing a "ghost" echo was seen on the morning of 24 April. This target first appeared at 10,800 yards; closed rapidly to 10,000 yards; remained at this range for about two minutes and then disappeared. The pulse rate was changed proving the contact to be a secondary echo. The pip covered more than ten degrees on the PPI and had the appearance of a large ship contact. Our position at the time: 20 - 45 N; 111 - 27 E.; contact bearing 225 true.

Aircraft contacts were made usually from twelve to twenty thousand yards. However, there were exceptions when planes closed to a shorter range before being picked up. Small sail boats averaged from seven to fifteen thousand yards, birds often appeared out to three thousand yards. The condition of the sea seemed to affect the operation of the radar in some cases. During rough weather the second sweep land echoes would usually disappear and the first sweep land ranges would be reduced. It was during periods of calm that the exceptional ranges were obtained. On the evening of 4 April a pip was seen close to the beach at a range of forty three thousand yards. Considering the range and the size of the pip the target seemed to be quite large. The range was closed. At twenty thousand yards the pip was still the same size. From fifteen thousand yards the pip was still the same size.

and yards the pip became weaker. It was just possible to keep contact at ten thousand yards. The target was finally identified as a sail boat. This phenomonon was believed due to favorable atmospheric conditions that probably produced air "ducts".

SJ-1 - Materiel:
There were no major breakdowns during the patrol. Only tube replacements and monitor adjustments were necessary with the exception. On April 9th, during a routine check it was found that the trace on the "A" scope did not appear. The 2X2 tube in the range indicator was replaced correcting the trouble. On April 15th intermittent noise and high grass was seen on the "A" scope along with changes in intensity on the PPI. The 717A tubes in the Transmitter-Receiver were replaced and two of the IF-tubes in the Range Indicator that seemed unusually noisy when knocked were also renewed. A new coax from the IF input jack on the front panel of the Range Indicator to the IF amplifier strip was also installed. Two condensers, C26 and C21.1, 21.2 seemed to be leaking badly and were also replaced. The trouble did not appear again. The flexible shaft that drives the PPI seemed to be broken or slipping on April 22nd as the PPI bearings and those of the bearing indicator did not agree. The trouble was due to the fitting on the PPI end of the shaft slipping on the flexible spring conductor of the shaft.

SD-4:
Good results were obtained from the SD-4. Flinois were usually contacted between ten and twelve miles and were followed out in some cases to twenty miles. The megger readings on the SD mast dropped to below one megohm after several all day dives. The insulator at the top of the mast was cleaned by scraping and with alcohol and the readings went up to infinity. However, after long dives the resistance would again drop. The trouble was corrected by cleaning the insulator and then applying two heavy coats of glycol to prevent water from entering the rubber cover of the insulator.

V. REMARKS:
There was absolutely no traffic along the east coast of Indo-China while we were there. The same is true of the east coast of Hainan. Any traffic which might have passed west of Hainan hugged the coast in the shallow water of the blind bombing zone, out of the reach of submarines.

While from the overall point of view it is encouraging to know that Japan's sea lanes between the empire and the Indies are definitely severed, it certainly makes for a disappointing submarine patrol.

Subject: U.S.S. BASIAW (SS241) - Report of Sixth War Patrol.

1. The sixth war patrol of U.S.S. BASIAW (SS241) was conducted in the SOUTH CHINA SEA off the east coast of FRENCH INDIA and in the area east of HAINAN and south of KWANGTUNG. The first part of the patrol was coordinated with BLUEBACK (Pack commander) B.H.G. L.L., BLUEGILL, and CROAKER. The patrol lasted for 34 days, four of which were spent enroute to and from SUBIC; 10 days were spent submerged.

2. Despite thorough area coverage and close in patrol of coastal traffic lanes no contacts worthy of torpedo fire were made. Three properly marked enemy hospital ships were sighted. The lack of enemy air activity off the IND CHINA coast is noteworthy.

3. Excess torpedoes and critical spares will be removed, voyage repairs will be completed and BASIAW will return to the United States for navy yard overhaul.

4. The squadron commander regrets the lack of targets encountered during this well conducted patrol and wishes the personnel of BASIAW a successful "Golden Gate Patrol" and an enjoyable period of well earned relaxation from combat.
