0330	SJ radar contact, bearing 226 (T), range 16,650 yards (ship contact #4). Sent out contact report to pack and commenced tracking from ahead on easterly courses.
0436	With U.S.S. ICEFISH in contact with target and 7000 yards to the north of us, dived for ST scope attack. Sea state 0 to 1, bright full moon behind target, and good solution of TDC. Target identified as class #7 Japanese minelayer (630 tons.)
0500	With target tracking smoothly on TDC at 13.5 knots, 80 degree port track, ST scope giving excellent results, gyros small, and run of torpedoes 1400 yards, fired full nest of Mk. 14-3A torpedoes forward with depth set at four feet and using a one degree spread to intercept 80 feet between torpedoes and insure a minimum of two hits. Torpedoes smoked badly but were observed to run hot and straight directly under the minelayer. Sound tracked the torpedoes directly through the target. No hits. Alerted by his narrow escape the target turned left down the torpedo wakes catching us in the act of turning to bring the stern tubes to bear so at...
0504	Went deep and rigged for depth charge. Much pinging and maneuvering by the minelayer, and at...
0522	Heard and felt fourteen depth charges, none of the charges were close.
0600	With minelayer's echo ranging becoming weak, bearing 100 (T), discovered new pinger at 250 (T), closing steadily. New pinger passed rapidly to the north of us and disappeared on true bearing 090.

1924	Sighted class #7 Japanese minelayer on horizon through high periscope, bearing 163 (T) (ship contact #8). Commenced closing target at flank speed on four engines while simultaneously maneuvering to avoid the submerged reef between Goa Goa and Kemirian Island. The minelayer tracked on course 270 (T) at 18 knots. Tracking resulted in a stern chase with nearest range 12,000 yards.
2110	Broke off the chase as the Jap approached the haven of Madura Strait minefields. Had previously received message from U.S.S. ICEFISH stating that she was unable to close the target.

0845	SD radar contact at 15 miles (plane contact #2). Plane closed to seven miles and was lost on radar at 10 miles going away. Not sighted.
0930	SD radar contact at 9 miles (plane contact #3). Plane sighted from bridge and identified as enemy twin engine bomber with zero angle on the bow. So at...
0933	Dived.
1038	Surfaced; all clear.

1907	Smoke sighted through high periscope, bearing 088 (T) (ship contact #9). Contact developed into five small targets on base course 255 (T) making 7 knots. Commenced tracking from ahead.
1932	SD radar contact at 24 miles (plane contact #4).
1937	SD radar contact at 16 miles (plane contact #5).
1941	SD radar contact at 18 miles (plane contact #6). All three contacts on SD radar scope at once; obviously air cover for small convoy.
2002	Lost last plane contacts on SD radar. Commenced maneuvering for surface torpedo attack on enemy's port flank. Moonrise is at 2235.
2127	Manned battle stations and headed in for attack on main target group.
2150	With range down to 3500 yards targets finally became sufficiently visible to be identified as three Sugar Dogs (400-500 tons), one Sub Chaser (SCS-1, 100 tons), and one smaller patrol craft. Withheld fire since targets are not large enough for torpedoes.
2153	Reversed course and pulled clear leaving targets alerted and maneuvering in tight circles. Resumed tracking targets while awaiting arrival of U.S.S. CAPITAINE. Contemplate suggesting a gun shoot.>

0125	Made rendezvous with U.S.S. CAPITAINE (ship contact #10). It was decided in conversation via VHF that the Capitaine would attack from the north while BAYA attacks from the west. Firing of the deck guns is to commence on receipt of "execute" from the U.S.S. CAPITAINE. The Sub Chaser will be primary target.
0152	"Execute" from U.S.S. CAPITAINE. Commenced firing with fuses set on super quick. Range to target 6000 yards, closing.
0154	Hit in Sub Chaser near stern.
0155	All ships in convoy are now returning fire. Range to Sub Chaser 4400 yards.
0155:35	Another hit in Sub Chaser. The Sub Chaser is firing a 37mm or 40mm, while the Sugar Dogs are returning fire with what are apparently 3" deck guns. The larger projectiles are not tracer but they can be heard whistling over the bridge uncomfortably close.
0156	Shifted local control at the guns and reversed course to open range. Guns fired by local spotting at several of the Sugar Dogs, and several doubtful hits or near misses were observed.
0204	Broke off the engagement and secured from battle stations. Damage inflicted: two direct hits in Sub Chaser, possible damage to two Sugar Dogs. These fellows can out-range us with their three inch guns.
0252	Made rendezvous with U.S.S. CAPITAINE to discuss further action to be taken. The U.S.S. CAPITAINE intends to make a submerged ST radar attack while BAYA stands by to capitalize on any confusion CAPITAINE may create.
0345	Made rendezvous with U.S.S. CAPITAINE. He is unable to make submerged attack since all targets are maneuvering radically and making no particular course good. He suggests that BAYA return to its Point Selatan-Kangean Island patrol line. After trying for another hour and a half to track targets on some steady course to permit a dawn attack, and finding them ever shifting direction of their advance, it was decided to leave their fate to the U.S.S. CAPITAINE.
0533	Lost contact by SJ radar at 14,000 yards.
0605	SJ radar contact, bearing 259 (T), range 18,000 yards (ship contact #11). Exchanged calls by radar with U.S.S. PUFFER.

1200	Lat. 5-18 S., Long. 114-14 E.; 180 miles, 1490 gals.

0658	Made quick dive for trim.
0710	Surfaced.
1200	Lat. 5-46 S., Long. 115-11 E.; 181 miles, 1145 gals.
2020	Exchanged recognition signals by SJ radar with U.S.S. Becuna.
2337	Changed speed to full on four engines, and set course to intercept BECUNA's east bound contact.

0059	SJ radar contact on U.S.S. BECUNA, bearing 279(t), range 15,950 yards (ship contact #16).
0130	SJ radar contact, bearing 273(t), range 20,100 yards (ship contact #17). Sent out Wopaco message to BECUNA informing her that BAYA has contact on her target. Commenced tracking from ahead on course 090 (t).
0140	Took grandstand seat while BECUNA commenced her attack. BECUNA maneuvered down target's port flank and conducted an excellent night surface attack; the two radar pips actually merged on the PPI scope at the firing stage.
0210	Received Wopaco message from BECUNA stating that all torpedoes missed with four foot depth setting.
0221	Manned battle stations. Target still tracking on nearly steady course of 090 (t): apparently not alerted by BECUNA's attack.
0238	Dived to SJ radar depth directly on target's track, range 12,000 yards. In view of BECUNA's misses with four foot depth setting, and our previous misses with a similar setting on steam torpedoes, it is decided to make a deliberate stern tube attack with electrics set on zero.
0246	Target tracking nicely on course 090(t) at 17 knots, night very dark but clear. Commenced turning off track as range reached 9000 yards.
0301	Sighted target through night attack scope; range 3000 yards. Shifted to ST radar ranges and increased depth to 58 feet.
0305:45	With perfect solutions from both TDC and Plot, gyros approaching 180 degree, track angle 90 degrees starboard, run of torpedoes 1100 yards, sea state one, fired salvo of three MK.18 torpedoes aft with zero depth setting and a 3 degree spread to intercept 165 feet at target. All torpedoes tracked hot and normal by sound.
0306:55	Observed and heard one hit in target near stern. Target tracked to a dead stop. He is burning fiercely abaft his after deck house and fire appears to be creeping forward causing numerous minor explosions on deck. By light of fire target is positively identified as an OTORI class Torpedo Boat (600 tons).
0352	The OTORI is still burning and flames have progressed on his port side as far forward as his stack. However, he is still on an even keel and there are signs of bringing the fire under control. Commenced maneuvering to target's starboard beam for a final set-up/
0426:17	With range of 2700 yards and target presenting a 115 degree starboard track. drifting with the wind on course 305 (t) at ½ knot, fired tubes No.1 and 2 forward with depth setting of four and two feet, respectively. Both torpedoes running straight and normal, aimed at MOT with a 28 second firing interval.
0428:00	Observed and heard hit amidships directly under the OTORI's funnel. This was a terrific explosion that completely disintegrated the Torpedo Boat. The second torpedo, trailing by a mere 28 seconds directly in the wake of No.1, found no target to hit.
0432	Surfaced; all clear. No signs of life boats or survivors.
0440	Secured from battle stations.
1200	Lat. 4-51 S., Long. 114-36 E.; 244 miles, 1985 gals.

0705	Made quick dive for trim.
0715	Surfaced.
1200	Lat. 4-23 S., Long. 112-42 E.; 196 miles, 3245 gals.
2230	Received CTG 71.1 instructions to patrol areas E-2 and E-5 during final week of patrol.

0030	Received instructions from ComWolf in U.S.S. BLENNY to join coordinated activities during afternoon and night of 18 July.
0758	SD radar contact at 27 miles (plane contact #13). Plane closed to 21 miles and was lost at 31 miles. Not sighted.
1120	Exchanged recognition signals via SJ radar with U.S.S. BLENNY.
1200	Lat. 5-47 S., Long. 114-28 E.; 276 miles, 2136 gals.
1400	Patrolling on station assigned by ComWolf in U.S.S. BLENNY.

0600	Departed patrol station and proceeded west to new area assignments E-2 and E-5 in compliance with CTG 71.1 instructions.
0725	Made quick dive for trim.
0740	Surfaced.
0933	Sighted JAKE II type plane, bearing 120 (t) (plane contact #14). Plane passed astern about 12 miles.
0942	Lost sight of plane, bearing 050 (t).
0950	Sighted U.S.S. BLENNY and communicated via VHF.
1200	Lat. 6-05 S., Long. 113-47 E.; 196 miles, 1230 gals.
1230	Sighted JAKE II type plane, bearing 042(t), range 12 miles (plane contact #15). Plane headed towards and closed range rapidly. So at...
1233	Dived to avoid.
1327	Surfaced; all clear.
2145	Converted 3 and 4 FBT's to MBT's
2251	Dived to flush converted FBT's.
2315	Surfaced.

0021	SJ radar contact, bearing 285 (t), range 13,300 yards (ship contact #19). Commenced tracking; sent contact reports to subs in vicinity. Target identified as small man-of-war type vessel, probably PC-4.
0030	Manned battle stations. Target tracking on a nearly steady course of 090(t) at 11 knots. It was decided to make a submerged approach using a salvo of torpedoes set at 2 feet.
0035	TDC out of commission; time motor casualty.
0045	DRT out of commission.
0050	Secured from battle stations until fire control equipment could be made operative.
0130	DRT back in commission.
0150	Target suddenly reversed course to 270(t). This is puzzling since it is fairly certain that BAYA has not been sighted. Commenced end-around at full speed.
0240	Having gained a position due north of target, the PC abruptly changed course to 130(t) and commenced tremendous constant helm zigs or about 90 degrees either side of base course. He is apparently patrolling; this new base course takes him directly toward Surabaya. Target is now echo-ranging occasionally.
0330	TDC is back in commission. Due to target's enormous zigs BAYA is having difficult job gaining position for attack. However, there is little to indicate that the PC is alerted; his maneuvers are apparently intended to waste time to permit a daylight entry into Surabaya Harbor.
0545	Made rendezvous with U.S.S. BLENNY (ship contact #20). Communicated via VHF. It was decided to make a coordinated gun attack on the PC at dawn; one sub attacking from the southwest, and one from the northwest.
0705	Manned battle stations.
0721	Received "execute" from U.S.S. BLENNY. Commenced firing from 8000 yards with both 5"/25 cal. deck guns. Target is returning fire with small caliber automatic weapons which are splashing just short of BAYA; she is returning the BLENNY's fire with what appears to be a 3 inch or six pounder. The PC is belching great volumes of smoke and is maneuvering at a speed approaching 20 knots. Submarine fire control is barely adequate to cope with this type of target, but it's causing him much confusion and loss of face; the hound attacked in his own back yard by the timid foxes! He is running for the barn.
0800	Ceased firing and broke off attack. Ammunition expended: 71 rounds; no casualties, and no hits in target who is fleeing very ungallantly.
0846	SD radar contact at 14 miles (plane contact #16). Plane sighted from bridge and identified as JAKE II type. He is circling posit of our gun shoot.
0928	SD radar contact at 14 miles (plane contact #17), plane sighted from bridge and identified as JAKE II type. Both JAKE's are searching vicinity of gunshoot.
1005	Lost contact with all aircraft.
1200	Lat, 5-43 S., Long. 111-14 E.: 287 miles, 2450 gals.
1900	Entered patrol area E.5.

0730	Made quick dive for trim.
0749	Surfaced.
1200	Lat. 5-26 S., 107-56 E.; 214 miles, 2365 gals.

0732	Made quick dive for trim; -- made an even quicker surface; #5 MBT vents had failed to open. Ship actually submerged to 60 feet with #5 MBT dry. This casualty was result of a recent alteration made at Subic which placed stop valves in hydraulic lines to #5 MBT vent gear. Valves were located in crew's shower in close proximity to shower control valves; someone had inadvertently shut off the return side which prevented operation of vent in either hand or power. Valves were opened and wheels promptly removed!
0736	Resumed trim dive.
0752	Surfaced.
1200	Lat. 5-09 S., Long. 107-31 E.; 201 miles, 1450 gals.

1338	SD radar contact at 14 miles (plane contact #19). Not sighted. Plane closed rapidly, so at...
1340	Dived to avoid.
1424	Surfaced; all clear.
1530	SD radar contact at 25 miles (plane contact #20). Plane closed to 22 miles and was lost at 26 miles. Not sighted.

1030	SD radar contact at 28 miles (plane contact #21). Plane not sighted; lost contact at 34 miles.
1050	SD radar contact at 23 miles (plane contact #22). Plane closed rapidly to 8 miles, so at...
1055	Dived to avoid.
1118	Surfaced; all clear.
1140	SD radar contact at 18 miles (plane contact #23). Plane closed to 12 miles and was lost at 18 miles. Not Sighted.

(C) WEATHER:

The weather was typical of the Java Sea area during the months of June and July. From 1 July to 8 July sky was largely overcast with low nimbus clouds and frequent showers. Cloud concentration for the remainder of the period averaged 20 percent. Visibility was excellent, temperatures consistent, wind velocity 10 to 12 knots from the southeast and seas mild. Average sea state one to two.

(D) TIDAL INFORMATION:

Eastern Java Sea currents were consistently westward at 0.6 knots. Currents in northern approached to Lombok Strait were southerly and variable in rate; one freak current of an extreme nature (at 400 feet) was encountered on 27 June which caused even full rudder to be ineffective at 3 knots. Central Java Sea currents were consistently westward at 0.5 knots. Northern approaches to Sunda Strait had a 2 knot southerly current on 22 July. Contrary to information contained in H.O. Supplement to Sailing Directions, the current near the coast between Cheribon and Semarang, Java, eddies strongly to the eastward at velocited of 1.5 to 2.0 knots.

(E) NAVIGATIONAL AIDS:

The following navigational aids were sighted:
(1) Edam Light, Batavia Roads; Group flashing every 9 minutes;
(2) Tegal Light, Java; Irregular flashes;
(3) Etna Rock Lighthouse;
(4) Discovery East Bank Lighthouse.

(F) SHIP CONTACTS:

In the war report this section contains all of the ships sighted during the patrol, their location, date of sighting, vessel type, range, course, how contacted (radar, visual, etc) and other remarks. This information, which is already presented in the Narrative section of the report is shown in a table form. If you are interested in this info, please email me and I'll send it to you.

(G) AIRCRAFT CONTACTS:

In the war report this section contains all of the aircraft sighted during the patrol, their location, date of sighting, aircraft type, range, course, how contacted (radar, visual, etc) and other remarks. This information, which is already presented in the Narrative section of the report is shown in a table form. If you are interested in this info, please email me and I'll send it to you.

(H) ATTACK DATA:

In the war report this section contains technical information (and a lot of it too) for the BAYA's two torpedo attacks and two gun attacks during the war patrol. The majority of this information is already contained in the Narrative section of the report. This section lists sea states, course and track info, as well as which tubes were fired, torpedo serial numbers, depth settings, etc. If you are interested in this info, please email me and I'll send it to you.

(I) MINES:

No mines were encountered.

(J) ANTISUBMARINE MEASURES AND EVASION TACTICS:

Antisubmarine measures encountered consisted of two patterns of seven depth charges dropped at a considerable distance following the attack on a Japanese Minelayer on 27 June. No unusual evasion tactics were employed. The small convoy attacked by gun fire on 30 June utilized their guns to good advantage, but effected no hits. Once alerted the convoy steamed on aimless courses until daylight and air coverage arrived. The PC-4 encountered on 20 July evaded torpedo attack (although it is doubtful that he was alerted) by reversing course frequently, making complete circles, and zig-zagging on no set base course.

(K) MAJOR DEFECTS AND DAMAGE:

Only one major casualty occurred during the patrol. A clogged drain in the ventilation supply line aft resulted in several gallons of condensate pouring from the forward starboard louver causing an electrical fire in the main control cubicle. One field and two armature bus bars to No. 3 MM were burned through. Fire from the bus bars burned through seven of the sixteen main power cables (to No.1 MM) running in a nest directly above the damaged bus bars. The bus bars were repaired and the cables renewed by SRU, Navy 137, Fremantle, W.A.

(L) RADIO:

No major defects or damage. Radio reception and transmission were both very good. The new short antennas amidships are excellent for transmissions and satisfactory for reception. It is believed that installation of a whip type antenna would improve reception.

(M) RADAR:

SJ Radar performance was excellent. Results were superior to those obtained during any previous war patrol. The ST radar was a valuable addition to the ship's radar equipment even though it was not effective at ranged beyond 10,000 yards when submerged to 58 feet. It requires frequent tuning for optimum performance. SD radar performance was average; maximum ranges for aircraft being about 33 miles.

The 6AC7 type tubes received from the U.S.S. CLYTIE were second hand tubes wrapped in old cardboard and represented as new tubes. All tubes showed usage and some were marked defective. When tested 90% of them showed a short and some of the remaining were unsatisfactory when their use was attempted in the Radar equipment. The 6AC7 is the most used spare in the radar equipment aboard this vessel and if supplies had run out might easily have impaired the safe conduct of this war patrol. It is urgently requested that activities using this method to increase their stocks stop the practice immediately.

(N) SONAR GEAR AND SOUND CONDITIONS:

Performance of sonar gear, both sonic and supersonic, was satisfactory. Sound conditions varied from good to excellent. It is suggested that a decibel meter be installed integral with the JT unit in place of the "magic eye." The decibel meter has twice the versatility in view of present JT uses.

(O) DENSITY LAYERS:

This section of the war report lists Isothermal levels/layers encountered during the patrol. If you are interested in this information, please email me and I will send it to you.

(P) HEALTH, FOOD, AND HABITABILITY:

The health of the crew had been good, and the boat was maintained in a satisfactory sanitary condition. There have been no vermin, but due to the boat's age and number of patrol runs it is desirable to have a carboxide fumigation prior to its next departure. The commissary department has furnished well balanced and healthful meals.

There were three injuries to personnel:
(a) A CMoMM received a piece of metal imbedded deep in the cornea of his right eye necessitating surgical removal. A corneal ulcer resulted, but was cured by use of Penicillin.
(b) While clearing the bridge a lookout struck his mouth and broke three teeth, two of which were forced into the upper jaw. One tooth was extracted and the patient transferred to the U.S.S. CAPITAINE for further transfer to a medical activity.
(c) While acting in the capacity of 40mm loader during GUN ATTACK #1, an EM2c sustained what is believed to be a ruptured ear drum.

Primary syphilitic lesions appeared in the cases of a MoMM1c and a TM3c early in the patrol. The men were placed under strict isolation and transferred to the U.S.S. ICEFISH for further transfer to a medical activity.

On July 24th, seven days prior to estimated completion of patrol, Atabrine prophylaxis was commenced for all officers and men.

(Q) PERSONNEL:

Number of men detached after previous patrol	13
Number of men on board at start of patrol	81
Number of men on board at end of patrol	78
Number of men qualified at start of patrol	59
Number of men qualified at end of patrol	66
Number of unqualified men making their first patrol	10

The performance of all officers and men was of the highest order, but it is still a losing battle to train new men properly in the ration of transfers of experienced men demanded at the end of each patrol.

(R) MILES STEAMED --- FUEL USED:

(S) DURATION:

(T) FACTORS OF ENDURANCE REMAINING:

(1) 8 Mk. 14-3A Torpedoes;
(2) 2 Mk. 18 Torpedoes;
(3) 5 Mk. 27 Torpedoes;
(4) 8000 gallons of fuel;
(5) 20 days of provisions;
(6) Personnel--20 days

(U) RADIO AND RADAR COUNTERMEASURES:

No radio or radar countermeasures were encountered. There was only one indication of the presence of enemy radar, this was the early warning radar at Lombok Strait.

(V) REMARKS:

None.

The Commander Submarines SEVENTH FLEET authorized the award of the Submarine Combat Insignia for this war patrol. and he congratulated the Commanding Officer, Officers and Crew of the BAYA for the aggressive patrol during which the following damage was inflicted upon the enemy:
