1st Set: Funnel Smoke 159 T.
    Our tanker in flares
    and down by stern 192 T.

: 2nd Set: Funnel Smoke 155 T.
    Flames and Smoke 172 T.
    Our tanker in flames 186 T.

: 3rd Set: Funnel Smoke 154 T.
    Flames and Smoke 170 T.
    Our tanker in flames 182 T.

These bearings are recorded in detail because they constitute the sole evidence of damage to the AK, at which two torpedoes were fired and on which hits were neither seen nor heard. The second small en- en- engines- aft vessel was never sighted after coming up to periscope depth, nor was the AK, and it is quite possible that the AK and engines- aft went over the hill together, one of them show- ing the funnel smoke; in this contingency the second fire would be from oil on the water given forth by the tanker. However, in view of the differences in bearings between the two fires (140 and 120) at a range of about 5,000 yards, a hit is claimed on the AK, and the attack data has been written up accordingly.

While "AKATAKE and engines- aft were getting farther away, commenced closing tanker and taking pictures of the fires. Rain interfered with photography.

As the rain died out, so did the fires on the tanker. It was soon apparent that the tanker would need killer shots. He got rid of his drag by the stern, extinguished all fires, and commenced tracking at 1 knot. The "AKATAKE and engines aft started heading towards us and getting closer. Depth charging had ceased. The tanker began to swing slowly to port, showing us his port side.

1517 H Fired 4 bow tubes at tanker, spread by periscope, 80% coverage, 2 ft. depth, 111 track (at time of firing), average gyro 3570, average torpedo run 1750 yards. Heard first hit and had periscope up in time to hear and see three more hits. Target disappeared almost immediately leaving a low (140), thin, patch of steam along his length and a small puff of black smoke where his bow had been. "AKATAKE had a bone in his teeth with the engines- aft tagging along. Did not appear to have time to get set-up on him.

1719 H: Reloaded.
: 1834 H: Surfaced.
: 1900 H: Set out down PALA'AY ASSAY to look for AK. Then RAY surfaced told him to form scouting convoy had anchored and would have coast from then on, and scented patrol south of URBANG. I felt, too, that the convoy's most probable destination was CFC'RY BAY and that we were following a slim hope in searching PALA'AY for him. Seas would not permit a speed of more than 11 knots. Reversed course and headed for patrol station of CALAVITZ.

2241 H: APR detected interference.

6 October

0240 H: SJ interference probably RAY.
0410 H: SJ contact 11,600 yards. Ship Contact No. 25. About 8 miles off CAP'S CALAVITZ. Tracked at 8 knots, zigging on 5 minute legs, course south. Closed and looked. It was a patrol craft, 3C size. Avoided. Lost radar contact at 13,510 yards.

0508 H: Submerged for day patrol.
1010 H: Sighted an unusual formation consisting of one BATTY escorted by 2 float-plares, RUTTS, headed for LANIA from southwestward. A/C Contact No. 11.

1114 H: Sighted 2-engine bomber. A/C Contact No. 12.
1306 H: Sighted unidentified plane. A/C Contact No. 13. At the same time sighted a rectangular object above the horizon which gave every appearance of a smoke pipe. Planed up and identified as a tree on the south shore of LUBANG ISLAND.

1825 H: Surfaced and headed for rendezvous with RAY.
2203 H: Received message from RAY that he was attacking convoy four miles north of LUBANG, course 230, speed 8. Set course to intercept and sent RAY probable time of interception. Sent this message blind, since RAY did not answer our callup.

2235 H: SJ interference.

ATTACK IC. 3

2342 H: SJ contact 20,250 yards. Ship Contact No. 26.

7 October

After one hour of tracking with no word from RAY, I began to wonder about KINSELIA. He would never wait this long to attack, I did not want to interfere with him; and I knew that he would rather expect first crack at the target since he had made the original contact. I even began to wonder if we were on the same convoy. It was not like him to keep quiet under these circumstances. I knew that he (or some sub) was on the surface, by the SJ interference.

0045 H Sent composition, position, course and speed to RAY. No answer, sent it blind.

0104 H FAY challenged us by SJ and sent message that he was working up ahead for an attack and that his transmitter was out. I still did not know that he had already made one hit in the target. Thought he was still making his first approach, but I could not let any more chances go by. Decided to get in at next favorable change of escorts' position.

0145 H Sent message to RAY (blind) that we were diving to attack.

0152 H Submerged and commenced approach from radar depth. Went to periscope depth at 3500 yards. Target chose this time to show us zero angle on the bow for ten (10) minutes and I guessed wrong as to where his next zig would be. We pulled off his track to starboard and he zigged to port, giving up a stern tube shot at a greater range than I had contemplated. Lt. Beckman was under the hood for his first live run and did a workmanlike job of calling bearings and angles on the bow. He could never call any angle but zero on the near escort, however, and this got on my nerves, so I had him devote all his attention to the target. The target was a very large oiler, engines aft, two tall masts, one short mast. The foremast was unusually heavy with heavy booms, not normally found on a tanker. It had a medium stack. Next day the largest escort

— page 4 —
0232 H Fired four (4) stern tubes, spread by periscope, 150% coverage, 6ft. depth, average track 104.05 yards. Started deep at once, counting on the explosion time properly for hits, and the RAY saw and heard two hits. Rigg'd for depth charge. Ran silent. They started going off six minutes after firing and there were only eight charges dropped, but the next hour was the most harrowing of my experience. There was a nine degree negative gradient start in at 235 ft., and we got under it in 1 minute and 42 seconds, slowed to 50 turns and commenced evasive tactics. There were two sets of screws, one fast and one slow. They would ping and listen. I tried to put them astern; sometimes we would set one back on the quarter, only to have him make a run across to our other bow, passing ahead or directly over. They stayed one on either bow most of the time, and would turn and make their runs over to the other side. I have spent many hours in the A/S attack teachers at TCU and FRAT, and many of the runs this night were good. There were some runs without sufficient lead angle, when the A/S vessel would pass directly overhead, but the only added to the discomfort. At one time the maneuvering room reported our port screw making a "squishing" sound. This turned out to be the slow speed escort passing overhead. On another occasion both vessels were milling about overhead and I thought surely they must be using a depth finder. And all of this was carried on in the utmost silence. Not a charge was dropped after the first two-minute barrage. It is impossible to describe the tension attached to listening for the charges when you know that the scoundrel is in a food dropping position and he does not drop. I could not believe that they could hear us through the gradient, yet I could not understand why their search did not take them farther afield. Found myself wishing that some charges would be dropped so that we might speed up in the confusion and

1035 H Had now reached position 8 miles on tanker's beam. In one hour he would be in 8 fathoms of water. "With a 7 knot speed advantage, the situation looked hopeless. Broke off and submerged. Set course to N across PALAWAN PASSAGE. Stayed at 200 ft. until every one had four (4) hours sleep. We needed it. Kept sound watch.
1817 H Surfaced.
1915 H Received message from RAY suggesting rendezvous at dawn if there were no fur ther contacts during night. Agreed and told him the bad news on the tanker.

8 October

0140 H Weak SJ interference.
0453 H Exchanged recognition signals with TAY by SJ.
0515 H SJ contact 8,700 yards. Ship Contact No. 27. RAY. He came close aboard and passed over wolf-pack instructions by line-throwing run. Exchanged information. He had made his first attack on the tanker at 2145 and scored one hit. He had seen and heard both of our hits. On his second attack he had been forced deep but had heard four explosions. The tanker had been making ten knots when first picked up, north of LUBANG. Assigned patrol stations and set off for ours, close to CABFA ISLAND, on a northeasterly heading.

ATTACK NC. 4

1100 H Lookout sighted mast astern, bearing 2330T, range about 18,000 yards. Ship Contact No. 28. This was a warship of about 1500 T, coming up from astern, zigging between 0250T and 0650T, making about 18 knots. Went to four enrines and tracked him from ahead with high periscope until range began to close to touch. His destination was apparently the same as ours, CABFA ISLAND, and we were on his base course.
1128 H Submerged. Had angles on the bow starboard, port, then starboard, then zero, for the next four zig legs. Everything was going nicely. Set depths 2 ft. Target then made a wide zig to the left of 60°, putting us well off the track. He was of about 1500 tons, had a tripod.

— page 7 —
1 CL (JU) 1500 tons

After his wide zig to the left, target zigged back, giving us a shot at 3100 yards range. Decided to take it. I was to report this decision later, but at the moment it was just a ship, and we had a chance to sink it. The control party, of course, was all for giving him the works.

1203 H Fired 6 bow tubes, spread by periscope, 200% coverage, 2 ft. depth, average track 104.5, average gyro 007, torpedo run 3100 yards. Noted while firing that the rail was manned aft on the target. There was no doubt why we missed; the target saw them coming, turned right and avoided them. He was headed directly at us when I next put the scope up after firing. Turned to right and went deep. Target drove a pattern of 5 charges, fairly close. "As hoping for a stern tube set-up until the last minute, so did not have the doors closed aft in time. Bent depth setting spindle on No. 10 tube and gyro spindle on No. 9 tube. Kept dead with spars. Lost power on bow planes for a few minutes. No other damage noted. Could still hear no echo-racing on target, and he soon left on his critical course. "He headed in opposite direction at periscope depth.

1813 H Converted No. 4 to ballast tank and flushed cut.

1829 H Sunk.

1911 H Sent COD HIV to Force Commander, "living results of wolf-peck to date and torpedoes remaining. Sent orders to FAY to form north-south patrol.

0915 H Submerged.
: 0958 H Surfaced.
: 1914 H Assigned new patrol stations, forming a submerged line NW of CABRA by day and a patrol north of CABRA for CCD at night. Left it for new station.
: 2200 H Decoded BECURA's report of attack on convoy at 1700. Could not make out whether BECURA had lost contact, from his report, nor whether convoy was headed into DANGEROUS GROUND or PAIA'AN PASSAGE.
: 2305 H Decoded report of CAVALIA sighting some convoy at noon. The two positions showed the convoy headed for DANGEROUS GROUND.

10 October

: 0125 H Decoded report that HAWKBILL had sighted convoy going into north end of PAIA'AN PASSAGE at 2300. Came to 4 engines and headed south.
: Estimated situation. Convoy had a lead of 150 miles. We had a nine-knot speed advantage. Fuel was a factor. If the convoy did not hole up in the nearest shoal water after experiencing a successful attack, it would be the first low-speed convoy in this area not to do so, to try 'knowledge. We had no reports of anyone trailing him to see where he took shelter.
: 0200 H Decided not to form scoutin line with RAY, reversed course and headed for station of CAFFA. Decided to patrol this station 25 miles NW of CABRA on the surface, until forced down by plane. Passed what appeared to be a bloated human body.
: 0610 H OOD sighted BERRY about 6 miles. A/C Contact I.
: 16. Submerged.
: 0958 H Sighted formation of three (3) TILLS, headed south, A/C Contact I'0. 17.
: 1831 E Surfaced.

1850 H Searchlight drill on COHENIDCR. Observed this almost every night while in this area.
: 2127 H SD contact, 11 miles, closing. A/C Contact No. 18. Submerged.
: 2207 H Surfaced.

11 October

0333 H Received contact report from RAY, south of LUBANC, of a destroyer northbound through CALAVITE PASS at 15 knots. If he were headed for IANILA, we might have just intercepted him off EL PRAILE. I had no desire, however, to fight it out with a single destroyer at night in shoal water under the guns of CCF-REGIDOF. Did not chase.
0705 H SD contact, 11 miles, closing. A/C Contact No. 19. Submerged.
0815 H Sighted plane, probably VAL, headed east. A/C Contact No. 20.
1030 H Sighted unidentified single-engine monoplane headed N3. A/C Contact No. 21.
1215 H O.C.D. sighted what he thought was a mast and headed for it. Disappeared.
1408 H C.O.D. sighted smoke close to beach north of LUBANC ISLAND. "e watched this all afternoon and at night we went in to investigate it.
1445 H Sighted two-engines bombed HARD. A/C Contact No. 22.
1728 H Thought we heard pinning from direction of LUBANC.
1817 H Surfaced. Ran east along CABRA ISLAND shore and investigated anchorage north of LUBANC. All clear by radar. Headed out for new station 20 miles off CALAVITE, with RAY close in.
    Received orders. RAY was to leave for new area at dark on the fourteenth. COD was to assume lifeguard duties off SUBIC BAY from dawn sixteen through eighteen October for carrier strikes. BLUCKILL and ARCLIK were to move in to our present area at dark on the fourteenth. That left us the fifteenth without definite assignment, but the intent was clear enough. Decided to spend that day in the WEIC area, which would then be vacant.
2348 H Sent COD SIX acknowledge receipt of orders.

12 October

Tried to run this one on the surface for a while.
0753 H SD contact, 12 miles. A/C Contact No. 23. Submerged.

— page 10 —
1331 H When 19.5 miles west of CAP3 CALAVITI heard a tremendous explosion from the direction of the CAP3, where the RAY was. Saw clouds of intense white smoke rising from a spot about 5 miles north of the CAP3. Decided we had better get over to help the RAY and look for the remnants of whatever he was attacking. Iade preparations for surfacing.

: 1348 H Fourteen explosios on, about four (4) seconds apart.

: 1353 H At 50 feet, making 3D search.

: 1356 H 3D contact & rifles, closing. Closed to 6 miles. "ent to 100 ft. Heard 21 distant explosions of three with about four (4) seconds between each group.

: 1405 E At 60 feet.

: 1412 H All clear on 3D.

: 1416 H Surfaced and headed over for CALAVITI at four-engine speed. Nothing in sight.

: 1500 H C.C.D. sighted plane, PTT3, toward CALAVITI, distant about 6 miles. A/C Contact No. 25. Submerged.

: 1815 H Surfaced. While on the surface before, we would have sighted any remnants from the RAY's attack, had they been headed southwest or south across the mouth of ITIDORO STRAIT. However, a ship might have escaped by hurling the coast of ITIDORO. In this event, the most likely harbor of refuge would be PALAU PAY, where the TUSKALIUTZ had once picked up a convoy. Headed over to mouth of the bay. All clear. Headed out.

: 1918 H In reply to question, received message from RAY that he had sunk a large ammunition ship and that there were only two (2) CIDORI's left of the convoy.

: 1940 H Received message from RAY that he had radar contact on convoy one (1) mile bearing 300T from CALAVITI, course 230, speed 9. Set course to intercept and informed RAY of probable interception time.

: 2001 H 3J contact 19,950 yards. Ship Contact No. 29. Two (2) ships, course 192(T), speed 10. Corr. mened tracking and sending information to RAY. The contacts appeared to be a little smaller than destroyer size. They were raking a sweep off CALAVITI, working through courses 3', 4' and 5', to N. "We were making an end-arcund to port and had so informed the RAY, so I was such surprised to pick up the RAY on the radar on the targets' port flank. Asked him 'Are you on

0638 H Sighted plane, KUFJ. A/C Contact No. 38.
0720 H Sighted plane, KUFJ. A/C Contact No. 39.
0721 H Sighted plane, BETTY. A/C Contact No. 40.
0940 H Sighted smoke, followed by masts, to northeast. Ship Contact No. 30. Closed and investigated. Contact turned out to be two small engines-aft vessels, with two masts, patrolling off FALAUIG FEF. They reversed course from south to north while we were watching them. Echo-ranging. A total of three (3) were seen during the day, running a patrol at 6 knots about one mile off the reef. We stayed to seaward of them and in the afternoon ran north and patrolled off POFT TATALVI.

1442 H Sighted two (2) sailboats close to beach. Ship Contact No. 31.

1821 H Surfaced. Headed over for lifeguard station, thirty miles west of entrance to SUBIC BAY.

0719 H BN signal 26 miles, opening. Code 1. A/C Contact No. 47.
1350 H Sighted sailboat, about 12 miles. Ship Contact No. 34. Avoided.
1819 H (Dark) C.C. and O.C.D. both noted a strange phenomenon in the water. At intervals of several seconds, patches of smooth water near the ship would be lighted with a momentary glow as if some yard-lor patch of phosphorescence suddenly had its lights turned on under the surface. I have never before seen white flashes in the water.
2326, 2340 H SJ contacts on sailboats. Ship Contacts Nos. 35 and 36. Avoided.

18 October

0407 H Submerged.
0505 H Surfaced.
0516 H Sighted a red glow over SUBIC BAY. The hoped it was an indication of our bombers at work, but it may have been connected with the sunrise.
0701 H Lookout sighted flight of six (6) planes headed south along coast of LUZON. Appeared to be TBF's. BN signal at 40 miles, closed to 25 miles. Sighted more planes coming astern of the original six. A/C Contact No. 42.
0710 H Lookout sighted two (2) small planes headed north past LOS FIALIS. Appeared to be fighters. SD pip at 10 miles. A/C Contact No. 49.

— page 14 —
0735 H C.C.D. sighted large unidentified plane headed north along shore. A/C Contact No. 50.
0822 H J.C.C.D. sighted plane, DAVE, 7 miles, low, closing. A/C Contact No. 51. Submerged.

1140 H Investigating possible smoke on hori zon.
1244 H Returned to station.
1313 H C.C.D. sighted plane, SALLY, 10 to 14 miles, headed toward us from beach. A/C Contact No. 53. Submerged.
1347 H Picked up plane, assumed to be same one, in periscope. He was apparently searching. Disappeared to northwest at 1353.
1423 H Surfaced. A line squall was headed our way from the southeast with rain clouds scattered here and there. Evarythin seemed blue and purple. Steered various courses, trying to keep out from under the clouds, with the two-fold purpose of improving electronic performance and attempting to be on our flyers' most probable route. Fan directly through the squall at right angles to its front when it reached us.
1427 H BN signal 16 miles. Lookout sighted 4 planes headed east toward BATTAH. A/C Contact No. 54.
1435 H BN signal 26 miles. Nothing sighted. A/C Contact No. 55.
1455 H BN signal 26 miles. Nothing sighted. A/C Contact No. 56.
1545 H C.C.D. sighted flight of planes approaching from south. Initial BN signals from 22 to 26 miles. Counted 30 planes in all. Appeared to be SB2Cs and F6Fs. This was what we had been waiting for. The planes were headed northeast for SUBIC; we set course to intercept them. Two fighters peeled off as if to investigate us, so we turned right and showed our silhouettes. They passed up our port side, six miles away, and I hope they got half as much satisfaction out of knowing that we were there as the COD did from being on hand to help them, with her BX lit off, searching light rigged, flares mounted, and colors flying. I could think only of:

"For I dipt into the future, far as human eye could see,
Saw the Vision of the world, and all the wonder that would be;
Saw the heavens fill with commerce, argosies of magic sails,

0001 H Orders to lifeguard duty had read "from dawn
sixteen througheighteen:October." Believed
strikes were finished and lifeguard duties cor-
pleted, so shifted voice receiver from lifeguard
frequency to area frequency. Commenced
patrolling in area. Heavy seas; rain and wind.
0324 H 3J contact 14,100 yards. Ship Contact No. 37.
Commenced tracking. Radar pip showed a ship of
about DD size. Tracked on base course 135,
speed 7 to 8. Position was about 45 miles west
of SUBIC BAY; this course headed the target
across the entrance to IANILA BAY. Tried to
get ahead of target at 2-generator speed, but
the seas were so heavy that green water was
coming over the bridge. We were overcoming this
obstacle by closing the upper conning tower
hatch on warnings from the O.O.D. This system
broke down when the C.O. happened to be in the
hatch at the wrong time; the man at the hatch
felt a natural (and praiseworthy) reluctance to
close it on the C.C.; the diving officer got
the lower hatch closed, but we were ankle deep
in the conning tower. Tried to drive through
the seas on 4 generators, but could not get
more than 11.5 knots.

: 0239 H SJ contact 10,600 yards. Commenced tracking. Position 15 miles off CLINIAO. Radar operator judged it to be a small craft. Target was steerin' southerly courses, ziggin', at 6 knots. Closed and locked. Radar operator was' right. A small patrol boat, rakin' a sweep. Lived in between him and beach for day patrol.
: 0405 H SD contact 7 miles, opening. A/C Contact No. 66. Submerged. Submerged patrol.

GUN ATTACK NO. 1
: 0652 H Sighted sails bearing 024(T). Ship Contatc No. 40. On closing to investigate, the contact proved to be five (5) sea trucks, motor driven with foresails rigged, headed south for ECLIAO. I let the C.O.D. talk me into a battle surface, although we were only five (5) miles from the 100 fathom curve north of ECLIAO HAFBOR. Let them go by, came to parallel course, distance between tracks about 4000 yards, and made plans to pick them off with the 4" gun, starting with the one astern.
: 0818 H Battle surface. Farce 3900 yards. The third shot from the gun was a hit, but had no effect on the target. The foot-firing mechanism then jammed and it took a few minutes to rectify. Meanwhile, all five (5) sea trucks had turned toward us and were spraying the water with shells of about .30 to .50 caliber. Their shot was falling about 1000 yards short, but the ricochets were siring all around us. Turned away until

0924 H Sighted another sea truck about 10 miles astern of the first group. Called L" run crew to their stations again to try to let them save their faces.

0927 H 3D contact 10 miles. A/C Contact No. 67. Cleared deck. Closed to 6 miles. Submerged. Lost breech cover of gun. In reviewing this fiasco I can see that more sea trucks would have been sunk had I dashed in to close range with 20 mms, machine guns, and 4" all blazin'. Perhaps I should have.

1028 H Surfaced. Tryin' to get away from the scene.

1042 H 3D contact, 21 miles, closing. A/C Contact No. 68. This was followed by another rip at 18 miles, the second one very large. O.C.D., high periscope, and lookout then sighted the planes, moving south along the shore by SAN FRANCISCO. Counted 20 planes, with more lost from sight in clouds. Judged that these were reinforcements flown in to oppose our task forces and that a contact report was in order. Accordingly en-ciphered COD 3VJN and cleared it at 1356.

1056 H 3D contact, 9 miles, closing. A/C Contact No. 69. Submerged.

0010 H Received orders to stay in area until further orders.

ATTACK NO. 5

0237 H SD contact, 23,070 yards. Ship Contact No. 41. Contact's position was 4 miles of the beach, north of VIGAR. Headed for it and started tracking. Radar showed four large ships in a rush line abreast, southerly course, about 1500 yards between ships, and five escorts, one on either beam, one astern, and two ahead. At no time was there any indication of radar on target or escorts. We came in from the west and sighted the near escort and the four large ships from a little abaft their

— page 20 —
0402 H With the leg one minute old, fired four gyro
stern tubes, 10 divergent sprcd, 6 feet depth,
average track 61° S, average gyro 171°, average
torpedo run, 4,28 yards.

Commenced tracking the near escort who
was on the target's starboard beam and headed
for us, swung left to formation course, and
built up gradually from 1/3 speed to full power
and pulled out of the formation.

The set-up was so good on the target that
I had the firecontrol tell me when to look
for hits. He did. There were no hits forth-
coring. The target never knew we were there.
(On the followin' right the target group was

0535 H Secured from battle stations and went to our two-section trackin' stations, which we had never used. Tracked target with high peri-scope.

0557 H Sunrise. It was becoming apparent that we were tracking an ASIAN NAKU. Throughout the day the following points of similarity were checked with the photographs on page 1 of ONI-208-J, Revised: Two masts and two funnels, of proper proportions and properly spaced; high bridge, of proper proportion to forward funnel; poop deck higher than foc's' lie; foremast located at break of foc's'le deck; cross yards on masts; no smoke from funnels; size. There were no discrepancies from the photographs noted. The other three ships were AKs of large and modern appearance. All had block superstructures. Nos. 1 and 2 were IKBKM, with funnel abaft the center of the superstructure. No. 3 was IKPKM with funnel in center of superstructure. At least one had topmasts painted blue-green. Various ones smoked. C.C.'s estimate:

1. Large AK, ASIA NAKU class (3C) 16,975 tons
3. Large AKs (JU) 7,500 tons

No effort was made to close the escorts to a range perrittin identification. All that were seen were small.

0601 H High peri scope sighted plane over formation. A/C Contact No. 84.

0620 H SD contact 15 miles. A/C Contact No. 55. Sighted this plane astern of formation.

0635 H SD contact, 5 pips between 10 and 11 miles. A/C Contact No. 86. Closed to 8 miles. Sighted planes headed our way from target formation. Submerged.

0729 H Surfaced. Targets had been tracking on 260(T) since the first contact report. They were not in sight when we surfaced. Set out after them on 270(T). It did not appear that they were headed for LANIIA. That meant that some outfit other than subs of T.F. 71 would have to get them. That, in turn, would require many contact reports from us, both in order to keep the attacking forces informed (whoever they might be) and also to assure the attacking forces that we were acting with good faith and determination, and would not suddenly leave off tracking after

— page 23 —
0738 H Transmitted our second contact report. Addressed this one to CHINA AIR FORCE, also, since it appeared that the targets were headed for INDO-CHINA. Also broadcast it on the area frequency.

: 0745 H C.O.C.D. sighted a large flying boat, NAVIS, crossing our stern, about 9 miles. A/C Contact No. 87. Lost it in the clouds at about 15 miles.

: 0838 H High periscope sighted target. He had been making good about 200(T) since our last observation. Locked like he was headed for NAIR.

: 1015 H Target came to course north and then started working around to the east. Speed had dropped to 14 knots through the water. He was still zigging every five (5) minutes. He settled down on base course 060(T). This was heading him for CAPT ECTADCF.

: 1127 H Sent our third contact report. Named the ASIA TAFU in this report. This was also addressed to the CHINA AIR FORCE, to let them know that the convoy was no longer headed for their area.

: 1151 H O.C.D. sighted two (2) planes over targets. A/C Contact No. 38. SD contact at 15 miles. Faded.

: 1308 H 3D contact 10 miles. A/C Contact No. 89. Faded.

: 1344 H High periscope sighted a single, unescorted, unidentified merchant ship that appeared to be a medium AK. Ship Contact No. 42. He was proceeding on a southerly course and crossed about 8 miles astern of our convoy. I thought it must be a hospital ship, but could see no indication of hospital markers.

1355 H SD contact 12 mils, closing. A/C Contact No. 90. Three pips. Closed slowly to 6 miles. Submerged. "Attched and heard the targets go by and also had a look at the unescorted southbound ship.
1633 H At 50 feet preparing to surface. SD contact 7 miles. A/C Contact No. 91. Faded at 8 miles.
1637 H Surfaced. Convoy in sight heading southeast.
1658 H SD contact 14 miles. A/C Contact No. 92. Faded.
1717 H SJ contact on tarrets, 30,100 yards. We were able to hold the ASAA at 36,000 yards.
1732 H Sunset.
1738 H Received orders that we were to rendezvous later with BREAK to take off his prisoners.
The DEAI was now stuck, and the Navigator was lost until he worked out some stars. Meanwhile, I let the enemy do our navigating for us, and followed them south along the coast very close to the beach. The O.C.D. picked up the white water tower at VICAR in the twilight. Crossed it with some peaks and tan-cants and got ready to send our next contact report.
1907 H Weak SJ interference ahead.
1913 H Transmit ted contact report to VIC, having first sent it blind on the area frequency. Exactly when this transmission was completed, the escort on the near quarter turned on his searchlight and started shooting. We were on the beam of the ASAA at this time and had closed him to 13,900 yards. The moonlight was very bright, from our side of the formation, but we were not silhouetted. Could not see any splashes. Opened the range. The escort swept with his searchlight twice again during the next ten minutes, hesitating ever so little on our bearing during one sweep. Various ships in the formation exercised their guns at intervals for the next 65 minutes, the loudest noises and brightest flashes coming from the direction of the ASAA itself. Ensign KIMBALL, the C.C.D., was very happy about all this, as he had always been at the diving station when we were being shot at during previous patrols. For my part, I was happy not to see any splashes nor hear any shells.
During the shooting, the SJ interference had grown steadily stronger from ahead. It could only be one boat.
2013 H Using the last name of the C.O. of that boat for a call, we raised him on the area frequency.

2020 H (During the above) SD contact 10.5 miles.
    A/C Contact No. 93. Faded at 14 miles.
2048 H SJ contact on the other submarine. Challenged
    him and worked him by SJ. Broke off this con-
    versation in the middle at 2125 as it was
    fruitless and we had lost track of the con-
    voy. Went on down the coast.
2130 H Regained contact on convoy. They were still
    hugging the coast.
2215 H SD contact 7 miles. A/C Contact No. 94.
    Faded at 6 miles, reappeared at 8 miles,
    faded at 9.
2229 H Convoy had rounded RACE RIF off SAFFHANDC,
    slowed, and entered LINGAYEN CHIEF. We headed
    west and patrolled north of CAPT BOLTAC,
    waitin for him to come out.
2306 H Heard four (4) possible explosions through
    the hull.

26 October

0127 H Transmitted COD TIGHT to CTF 71 giving am-
    plifying data on convoy.
0505 H Submerged north of CAPE BOLITAC.
0520 H Heard cne (1) possible distant explosion.
0658 H Sighted two (2) ships and three (3) planes,
    one flat type at about 8 miles, and two (2)
    NELLS at 2 miles. A/C Contact No. 95.
    Heard echo-ranin. The planes presented a
    problem, as the NELLS were an effective A/S
    cover. They were flying very low and dainty
    figure of eights ahead of the ships. The sun
    was almost behind them. However, instead of
    flying separate courses, one would follow
    right astern of the leader. This simplified
    our problem. We would watch them heading for
    us from 65 feet, never training the periscope
    between them and the sun; we would wait until
    they turned; then plane up for a look at the
    ships; then run the scope down before the
    NELLS had started their turn back towards us.
    Then we would go back to 65 feet and start
    over. By this means we saw the blue-green top-
    masts of one of the AIS, many masts, and the
    twin funnels of the ASAIAART. They were
    headed south and hungin the coast. We want

1025 H: SD contact 7 miles, opening. A/C Contact to 96. Sighted from bridge.
1029 H: Transmitted contact report.
1050 H: SD contact, 11 miles. A/C Contact to 97. Closed to 5 miles. Submerged. Did not surface to chase convoy any further because:
(1) I was now sure he was headed for [ANILA] and (2) There was only one boat between us and [ANILA]. I was sure that he would be down for the day, and I expected that he would be on the convoy's track.
1831 H: Surfaced. Headed out for western part of area.
1957 H: SJ interference.
2050 H: Additional SJ interference. There were two radars in the vicinity on bearings 0550T and 0710T.

27 October

0146 H: 0.0.D. and lookout sighted first of a series of flashes from the bearing of the southernmost radar interference. Flashes were observed three times during the next 20 minutes. No signals on the area frequency.
0410 H: SJ contact 26,200 yards. Commenced tracking. Apparently atmospheric.
0702 H: Submerged.
0758 H: Surfaced.
1010 H: Lookout sighted smoke bearing 3030T. Ship Contact to 43. Commenced closing. Smoke disappeared then reappeared at 1325 on bearing 2400T. Commenced tracking by high periscope. Target was a single unescorted AK snorkler intermittently. He judged it to be a medium sized ship for want of better data. Base course 1400T, speed 7 (or the vectorial equivalent), heading for [ANILA].
1626 H: Decoded orders [RIVING: time of rendezvous with ENZA].
1629 H: Transmitted first contact report in aircraft code to CTF 71 with information that we were trailing and could be called by voice.
1737 H: Sunset. Closed target to 16,000 yards for a better look in the twilight. It was a large AK, having mast, bridge, signal mast, funnel, low mast, and mast in that order. There was a structure of some kind directly forward of the funnel. The funnel was old-fashioned and high.

1 Large AK (EU) 7500 T.

There was no escort.  Iadar picked up target at 24,300 yards.

1912 H Sent second contact report after getting star fix and checking target speed at 10 knots.  All boats would normally be on the surface when this report was transmitted on the Bakers.

2006 H Broadcast contact report on area frequency.  An unidentified ship received for it but was never heard again.

2018 H SJ interference ahead.  This was lost in an hour.

2026 H Received message from BREAK giving his probable time of interception.  Sent BREAK two more contact reports giving target's latest position, course and speeds; zig plan, speed through water, base course, etc.

2142 H "leak SJ interference on starboard beam.

2150 H Docoded a message to the BREAK from the Baker schedule giving him the data from our first contact report.  This message had a time group of 1914 H.  It is not apparent which message first reached the BREAK.

2315 H SJ interference.

23 October

0012 H "working BREAK on area frequency in plain language.

0044 H BREAK had made contact.  Asked him if he wanted us to call the zigs, which he did.  We were 16,000 yards directly astern of the target and could easily watch the zigs in the bright moonlight.  Commenced sending tracking data on an average of once every two minutes and could not read for the next two hours.

0103 H Target commenced shooting and turned left.  BREAK indicated submergence by not answering us on the radio.

0113 H Last shot from target.

0116 H SJ interference from BREAK, back on the surface.  Sent latest course and speed.  BREAK had contact and was chasing.  Target had reversed course and speed up from 9.5 to 10 knots.

0213 H Target came to course.  North.  He then commenced zigging at random between courses North and Last.

0243 H SD contact. 21 miles. A/C Contact No. 98. Faded at 24 miles.
: 0246 H Received message from BREAK of which we could not make out the meaning. Interpreted it to mean that he wanted us to keep quiet as he thought the target was listening on the voice frequency. Accordingly maintained radio silence for the next two (2) hours, but could not detect any change in the target's tactics as a result.
: 0443 H BREAK broke off attack. Ceased tracking. The target was now zigging more violently and was last tracked on a northwesterly course.

    Commenced tracking. Yesterday course. The
    following characteristics were apparent: Clean
    fuel's (no run nor other large item visible)
    very low silhouette (about the height of ours),
    no periscope shears, no radar mast, no high
    periscope, short in length, diesel driven, box-
    shaped superstructure, no 20 mm guns visible.
    As the target had reached a position well abaft
    of our beam, apparently without sighting us,
    attempted to get astern of him to track.
    Came left 30 degrees.

1359 I Target disappeared from sight while I was
    looking at it. Enciphered and transmitted COD

1. MINES
: No mines.
: (J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS
: Nothing new in A/S measures was encountered, with the exception of the small explosions during depth-charging on 5 October, which may have been gunfire.
: Patrol craft were encountered as much as forty-five miles from the coast.
: Evasive tactics submerged wcrc conducted at 50 r.p.m., or nearly so, with shaft speeds staggered. The slow progress through the water at this speed limited our tactics to manoeuvers with the rudder to put the A/S vessels astern.
: (K) MAJOR DEFECTS AND DAMAGE:
: 1. Bow Plane Rigging Casualty:
: On 25 September 1944, while making 11.5 knots on the surface, the bow planes, having been rigged out, failed to rig in completely. On attempting to rig them in a second time a fire broke out in the rigging panel caused by an overload. Investigation showed the overload to be mechanical and not electrical. The gear casing in the forward torpedo room was found to be unduly hot (about 1350) and the oil in the gear casing was emulsified. The oil was drained out and the gear casing flushed with new oil; on flushing, part of a six penny nail was found in the drain. The lower half of the gear casing was removed and one-fourth inch of bronze filings and sludge was found in the casing. The steel worm gear had cut about 1/32" on the bronze bull gear and the teeth on both gears were rough. The bull gear was ground smooth in place; the worm gear was smoothed in a lathe. All bearings in the casing showed excessive rust; the forward worm gear bearing was replaced; there were no replacements available for the others.
: The gear casing was reassembled and the planes operated. The result was normal line amperage (64 amps), cool gear case and less noise.
: The entire bow plane rigging system will require realignment and replacement of worm and bull gear in forward torpedo room gear casing next refit.

— page 61 —
2. Casualty to Engine Air Induction Outboard Valve:

On 26 September 1944 on surfacing the engine air induction outboard valve failed to open.

The operating gear in the crow's mess was inspected, the moving parts of the operating mechanism were caked and nearly frozen with corrosion. The force required to shut the induction after once opened was beyond the strength of one man.

The present design of this induct ion valve inside the hull is of such a nature that only two of the pins holding the crosshead linkage can be inspected and worked on submerged. (In the shut position). It would be highly desirable to redesign the existing or install inspection plates on the casing to enable all three of the pins to be inspected and worked on while submerged.

The parts were freed with penetrating oil, cleaned and completely reerased. The induction then operated satisfactorily; however, the action is slightly sluggish.

Complete overhaul and replacement of parts will be required during next refit.

3. Bant Depth Setting Spindle:

Following depth charging on October 8, 1944, the depth setting spindle in No. 10 tube was found to be bent upon withdrawing torpedo from tube. The casualty is believed to have been caused by the spindle being only partially locked in the disengaged position, and upon depth charging the spindle was jarred into a partially engaged position. On attempting to withdraw the torpedo from the tube the spindle was bent. The bent spindle was replaced with spare and tested satisfactorily.

4. Bant Gyre Setting Spindle No. 9 Tube:

The spindle is believed to have been bent as a result of depth charging before the tube was secured on October 8, 1944. The spindle housing was removed from the tube, the spindle sleeve checked and replaced, the housing reassembled and tested satisfactorily.

— page 62 —
5. Loss of Hydraulic Oil in Forward Torpedo Room:

The jarring during the depth charge attack on October 5, 1944, caused hydraulic oil to be blown out of the vent on both windlass - capstan vent and replenishing tank vent and out of the bow plane rigging gear case in the forward torpedo room.

No material damage other than the loss of oil has as yet been noticed.

6. Repeated Failure of the DRAI:

Several times during this patrol the longitude indicator of the DRAI has stuck and failed to register. The same defect was noted on the last patrol and the tender during the last refit failed to correct this defect. (It was removed to shop, tested and inspected, reinstalled and procunced satisfactory).

The fault apparently is in the friction disc of the longitude input, and since the defect apparently cannot be remedied by tender force - a new DRAI is desired this coming refit.

7. Excessive Vibration of Stern Planes:

Early during this patrol a growl has developed in the stern planes. When moving the planes from dive to rise or vice versa in power, a growling noise is heard throughout the after torpedo room, and the movement of the planes causes the entire ship to vibrate. This vibration has become progressively more noticable throughout the patrol.

It is desired that the ship be docked this refit, the planes inspected outside the hull, the shafting and gearing inspected in order to ascertain the cause and correct the noise and vibration. The planes were inspected in SAIPAN, but the trouble could not be located.

8. Cracked Liner No. 2 Cylinder No. 2 Lair Engine:

On September 25, 1944, fresh water pressure on No. 3 Main Engine revealed presence of water in cylinder. The liner was found to be cracked, and was replaced with spare.

— page 63 —
9. Salt Water Pump Failure. No. 2 Main Engine:

On September 29, 1944, excessive water leakage around the packing gland on No. 2 Main Engine salt water pump was noticed. The engine was secured and put out of commission while a spare pump was installed. The engine was out of commission for a period of 25 hours during the exchange of pumps.

Inspection of the clld pump showed powdering of balls and broken ball race in the bearing, this causing the impeller to drop down against the suction pipe.

10. Bridge Talk. Back Casualty:

On 13 October 1944, the key on the bridge for the talkback flooded cut. At first it was believed that the cable packing was faulty but re-packing failed to keep water out of the box. Further investigation revealed that the flexible metal diaphragm was cracked at the point where the key lever goes through the diaphragm.

A new diaphragm was made from shim brass and to prevent this casualty from occurring again the diaphragm was not drilled to allow the key lever to pass through, but key lever was cut at this point and soldered to the diaphragm.

11. Bow Plane Casualty:

Following depth-charging on October 8, 1944, the bow planes failed in power and were shifted to hand power. Inspection showed a taper pin on the ("Rise-Dive" - "In-Out") handle in the control room switch box had worked its way loose and had fallen out. The pin was replaced and the bow planes were put back in the power position, necessitating hand power for about fifteen minutes.

12. Bow Plane Casualty:

On making a trim dive after leaving SAIPAN on the evening of the 8th of November the bow planes failed to tilt in power although the "cut" light was shining. Investigation showed that the "out" limit switch in the forward torpedo room had tripped before the contact arm connecting the rigging circuit had closed. The planes were shifted to

— page 64 —
13. No. 4 Main Generator:

On 11/11/44 while operating at 750 KW on propulsion No. 4 main generator was noticed to be snicking and sparking by the siler on watch in the engine room.

Another generator was immediately started and the load shifted from No. 4, which was then secured.

Examinations disclosed a "fish cover" condition, with molten brush holder metal thrown around the end-bell and riding around on the commutator. Numerous brushes had heated to an extent where the pig tails were unsoldered. The commutator was badly burned.

Molten brass and pieces of lithium were laying in the bottom of the casing. One chart brush was found thrown out of its holder and laying on a lower row of brushes.

It is believed that this brush wore down until the rivet and washer holding the pig tails rubbed on the commutator, bringing the slots and creating a short circuiting path with the resulting flash over.

Due to the extent of the damage to the commutator repair was not attempted. A visual inspection was made and ground readings were taken on

— page 65 —
11/7/44 at which time no defects were found. The
armature ground reading was 1/2 meters.

On November 19th, 1944, a generator corer.ced sparking badly. Inspection by removal of the end-ball and rotating the brush ring revealed uneven brush tension and one brush worn down to the edge of the rivet and washer. This is the same condition as was found in 10th, 4 generator and might have resulted in a "flash over" had not the condition been corrected in time.

(1) RADIO
Radio reception during this patrol was fair. The increased number of jammers on the VHF frequencies was noted with displeasure, but they are still only an annoyance. All messages are received from VHF with comparatively little trouble and very seldom badly garbled. The should express thanks to radio COCAI and radio PIMCO for their excellent service to us during our transmissions to the shore bases. They enabled us to get the message on the air in a minute amount of time and with very few errors. No more efficient stations than these two have yet been contacted. While in 17th, 11th rendered valuable help to us also. On one occasion the 7th. 3. COCAI attempted to call us on the 1st. 7th.

— page 66 —
1. Properly was temporarily rectified by installing a jumper across the switch and permanently repaired by renewing the bakelite insulating members. Several fuses were replaced during this period, their cause of failure believed to have been surges in voltage in addition to the fact that we keep low amperage fuses in the equipment as added protection to the parts. One fuse failure was caused by an arc in the line when the power terminal joins the set. The screw holding the terminal on the terminal block was just loose enough for a small arc to develop.

The carbonization of the insulation on the line from the bias resistor (F-39) to the modulator network allowed this line to short out causing fuse failure in one instance. This line was renewed.

During the trip from FRENANTLE to DARWIN, the radar did not perform as well as usual. No apparent cause could be determined while at sea. The equipment was tuned daily but maximum range on submarine was about 11,000 yards. At DARWIN the TR line was renewed and the ranges were again normal. Submarines could be tracked out to 15,500 - 16,000 yards.

The equipment was out of commission about three hours during the time we were north of the NAIY BARRIER.

The SJ was not overhauled during the last refit.

(2) SD-2 RADAR

The SD radar has been in operation almost continuously day and night since we left FRENANTLE. During this period of approximately 1500 hours this set has been out of commission only about two hours. The only casualty to the SD radar was the failure of condenser C 255 on two occasions. On each of these occasions the 2X2 hed to be renewed as the tr ce on the scope had doubled in length. The SD was deliberately placed out of commission at one time to renew the 8014-A tubes which had given indication that their remaining life was short.

The outstanding performance of this radar during recent patrols is due largely to the care with which it is treated and operated. This radar was not overhauled during the last refit.

— page 67 —
3) IFF

This is the first patrol that IFF has been installed on the COD. Its performance was very good throughout the patrol with no material failures. In many cases ranges on negative pips were around 30-40 miles.

Unusual performance of Model BN radio identification equipment.

On 1 October 1944 at 0138 while operating the BN identification equipment in the near vicinity of some high land a series of irregular negative pips were observed. The ranges of the larger pips coincided with the ranges obtained on the high points of the land by normal SD operation. It is believed that the BN receiver was picking up echoes from its own transmitter pulse, and performing in the same manner as any conventional radar equipment.

(N) SOUND GEAR AND SOUND CONDITIONS

No casualties on the sound gear were experienced this patrol. The selsyn indicator on the port sound head did not operate as smoothly as it should have during the trip from SAIPAN to PEAF. Examination showed the bearings in the unit were wearing down slightly. One of the slip rings had been burned slightly which also caused jerky operation. This may have been caused by moisture or dust in the selsyn unit. The slip ring was renewed to ensure perfect operation although it would have served a short time longer. The selsyn will have to be renewed during the refit.

No unusual sound conditions were noted during this patrol.

(O) DENSITY LAYERS

The density layers observed were identical with those listed in COD's War Patrol No. 4.

1. I can see no necessity for having the calls change at frequent intervals. Then frequent shifts of voice calls were adopted by the 3rd Fleet, it seemed to many of us that the resulting confusion outweighed any security factor that was attained.

Use of 3D Radar. During the major portion of this patrol we keyed the 3D radar for five (5) seconds out of every thirty (30), night and day. I am unable to point to any one plane contact and state that that plane was probably :attracted to us by the 3D. On the contrary, we watched some planes go by, on the surface, while the 3D was being keyed. But neither am I able to state that any one plane was radar equipped or was on a definite anti-submarine search mission. (Except those planes actually accompanying ships.)

In SAIPAN I talked to at least three submarine commanders who did not use the 3D at all in the area. Conditions are undoubtedly different in EMPIRE areas from those existin in the 3CUTT, 3ST PACIFIC, but by use of the 3D my watch officers and myself have felt a certain measure of security in surface patrol-ing, and have made ship contacts on the off-shore routes that we would not have made had we restricted our daytime operations to submerged patrol at the inshore focal points.

Personnel. The personnel of this submarine remain very :cresive. Lany of them were anxious to ask for a reload of torpedoes even when it would have entailed a patrol of more than 100 days. This spirit is gratifying.

Subject: U.S.S. COD Fifth War Patrol, comments on.

1. The fifth war patrol of the COD was conducted in waters west of Luzon and Mindoro under the command of Task Force SEVENTY-ONE. The patrol was of sixty-four days duration. The COD formed a coordinated search and attack group with the U.S.S. MAY, and as such the commanding officer of the COD was the task group commander.

2. The COD made five aggressive torpedo attacks and one gun attack; the COD carried only Mark 23 torpedoes and expended them all. A summary of torpedo and gun attacks follow.

Attack No. 1 - 5 October 1944 - This was a day periscope attack made against a convoy of one large tanker, one large freighter, two small engines aft vessels, and a WAKATAKE destroyer escort. The two large targets were singled out and four torpedoes were fired at the large tanker and two at the freighter. Two hits were observed in the tanker and one hit was probably made in the freighter. This attack was followed by depth charging which kept the COD down for but a short time.

Attack No. 2 - 5 October 1944 - On coming back to periscope depth about an hour later the COD noticed that the convoy group was still in the vicinity so went in for its second attack. The tanker, now damaged, was again the target; four torpedoes were fired with a torpedo run of 1,750 yards. All four hit and the target was seen to disappear.

Attack No. 3 - 7 October 1944 - This was a night radar submerged attack on a very large tanker which had already been hit with one torpedo by the MAY. Four torpedoes were fired and two timed hits were made; the MAY observed these two hits. This attack was followed by an aggressive anti-submarine hunt by the escort vessels. These hits created severe damage to the tanker but did not sink it. The COD later surfaced at about daybreak and set chase for the damaged tanker but was unable to reach it before it found safety in shallow water.

Subject: U.S.S. COD Fifth War Patrol, comments on.

Attack No. 4 - 8 October 1944 - This was another day periscope submerged attack made against a 1,500 ton minelayer. Six torpedoes were fired but the target saw the wakes and was able to take safe evasive action.

Attack No. 5 - 25 October 1944 - This was a night surface radar made on a convoy of four large ships heavily escorted by five escort vessels. The largest of the targets, which later proved to be of the ASAMA MARU Class, was singled out and the last four torpedoes were fired at this fast moving target from the best positions obtainable. Unfortunately, misses resulted even though the fire control problem had been checking perfectly.

Gun Attack No. 1 - 22 October 1944 - This was a day gun attack made against five enemy sea trucks. Various hits were made on one of them but the enemy escaped to safety by running into shallower water.

3. All of the above torpedo attacks were aggressively conducted. Good tenacity was exhibited in the COD's two attacks on the convoy hit on 5 October resulting in the sinking of that important ship. In addition to these five attacks, the COD, out of torpedoes, performed a splendid job of tracking the important ASAMA MARU convoy for approximately thirty more hours sending out reliable contact reports during this period.

4. The COD also conducted lifeguard duty for about a week of Manila Bay during the carrier strikes on Luzon. The COD also picked up six Japanese soldiers from the BRIMAN and returned them to Saipan.

5. The COD returned from patrol in fair material condition and a good state of cleanliness. The COD will be overhauled. The state of morale in this ship is excellent.

6. The Commander Submarine Division FORTY-FOUR, congratulates the commanding officer, officers, and crew for this successful successful war patrol and for having inflicted severe damage upon the enemy.

Subject: U.S.S. COD (SS224) - Report of Fifth War Patrol.
(16 September to 20 November 1944).

1. The fifth war patrol of the COD was conducted in areas west of Luzon and Mindoro under the operational control of Commander Task Force Seventy-One. Upon completion of patrol the COD took passage to Pearl Harbor enroute to the Navy Yard for overhaul. The COD and RAY formed a coordinated attack group during part of the time of this patrol.

2. Five attacks were made during this patrol. The first and second were aggressive and tenacious attacks against a tanker and freighter which resulted in the sinking of the former in the second attack. This second attack on the damaged tanker was an excellent example of how a kill should be performed even though anti-submarine activities forced evasive action after the first attack. The COD succeeded in damaging another very large tanker which was also hit by the RAY, but the tanker succeeded in escaping to shallow water before it could be sunk.

3. In addition to the damage inflicted above, the COD, although out of torpedoes, performed an excellent job of tracking an important convoy, including an ASAMA MARU type transport, for about thirty hours. The COD also carried out lifeguard duty off the north-west coast of Luzon during the carrier strikes in the vicinity of Manila Bay.

4. Award of the submarine Combat Insignia for this patrol is authorized.

5. The Commander Submarine Force, Pacific Fleet, congratulates the commanding officer, officers, and crew for this successful war patrol. The COD is credited with having inflicted the following damage upon the enemy during this patrol:

SUNK
1 - Large Tanker (EU) - 10,000 tons (Attacks Nos. 1 & 2)

— page 86 —
1. Large AK (HU)
1 - Very Large Tanker (EC)
1 - Sea Truck

TOTAL DAMAGED: 22,600 tons

14 April
0609 I Lookout sighted plane dead ahead, position angle 130, estimated range 5 miles, angle-on-bow zero, large 4-engine float type. Submerged. Lat. 29-16 N, Long. 133-42 E.
0616 I One bomb. Jarred loose one electrical connection in after torpedo room.

1212 I Lookout sighted plane, land based type, position angle 10, angle-on-bow zero, range not determined, closing fast. Submerged.
1310 I Surfaced.
1343 I Lookout sighted mine, our position Lat. 29-12.8 N Long. 132-13.2 E. Mine was round, no barnacles, floating about two-thirds submerged, four (4) horns visible. Appeared fairly new with only light coating of rust. Took pictures. 30 Cal. carbine slits bounced off the mine's case. Detonated mine with .50 Cal. fire. Range about 125 yards. Several pieces of spent shrapnel hit us.
1438 I Struck submerged object, heard throughout boat, loudest in forward torpedo room. Pit log out of commission. Rod meter bent. "we were unable to pull in the rod meter with a chain fall. Jettisoned rod meter and installed spare; completed repairs by 2012 I.
1518 I SD contact 8 miles, bogey. Submerged.
1608 I Surfaced in midst of much floating debris and oil slick. Apparently heavy diesel oil. Lat. 29-14 N, Long. 132-50.5 E.
1941 I SJ contact, 3 pips, 22,830 yards, went to tracking stations. Contact developed into 8 pips, opening rapidly, obviously aircraft. Secured from tracking stations.

14 April (Cont.)
sighted in the starlight with slight haze. Some were obviously phantoms since they would disappear, others tracked as birds, and still others gave good solid echoes in the same position down to range 400. "e maneuvered to avoid them all.

15 April
0333 I Entered strait south of AKUSEKI JIMA.
0425 I Airplane flare astern beyond horizon.
0723 I SD contact 12 miles, bogey. Closed to 10. Submerged. Periscope patrol.
1002 I Sighted mine, round horned type, many barnacles, took pictures through periscope. Lat. 29-58.5 N, Long. 128-47.2 E.
Noon Position - Lat. 30-05.7 N, Long. 128-47.2 E.
1500 I Held memorial service in after battery for the late FRANKLIN DELANO ROOSEVELT, President of the United States.
1728 I Surfaced.
1753 I Sighted tracer fire beyond horizon astern.
1849 I SD contact 12 miles, bogey, closing fast. Submerged.
1912 I Surfaced.
2111 I SD contact 12 miles, bogey. Closed rapidly to 8 miles. Submerged. Picked up by SJ at 12,900 yards on way down.
2135 I Surfaced.
2136 I SD contact 10 miles, 18,000 yards by SJ. Closed to 7 miles. Submerged.

2238 I Surfaced.
2316 I SD contact 6 miles, closing. Submerged.

16 April
0013 I All clear by ST, surfaced.
0022 I Observed flicker of light on bearing 230 T, believed from plane.
0108 I SJ contact 030 T, 8,850 yards. SJ interference on same bearing. Thought he was keying us but 8 minutes later interference disappeared. When interference reappeared, exchanged challenge and calls with SPADEFISH. Many floating objects during night which we maneuvered to avoid.
0135 I Sighted flicking object which might have been a mine; cur position Lat. 31-23.3 N, Long. 128-55.1 E.
0210 I Interference on SJ. Not SPADEFISH. Later decided this was a possible 10 centimeter radar on TORI SHIMA.

— page 93 —
16 April (Cont.)
0745 I Sighted floating mine. Our position Lat. 32-27 N, Long. 128-17 E. 3 horns and lifting hook. Commenced firing with .50 Cal. machine guns and .30 Cal. carbines; made several hits with no effect on mine. Gave up after expending 400 rounds of .50 Cal. ammunition. Decided we had better improve our mine shooting technique which we did by holding carbine target practice and by putting sights on our .50 Cal. aircraft guns. Also decided to try 40 MM and 5 inch on the next mine.
1000 I Lookout sighted 2 planes, probably TWILIGHT, angle-on-bow zero. SD contact 9 miles, closing, at same time. Submerged.
1042 I Heard a loud explosion.
1145 I Heard a distant explosion.
Noon Position - Lat. 32-33.5 N, Long. 127-36.7 E.
1208 I Surfaced.
1508 I Sighted object thought to be a mine. Investigation disclosed it as a bucket. Exercised rifle shots with .30 Cal. carbines at range of 150 yards.
2225 I Passed mine close aboard to starboard, plainly seen in moonstreak by lookout and OOD. Our position Lat. 32-22 N, Long. 125-27 E.
2226 I Stopped and commenced maneuvering to pick up mine with intention of sinking it. This maneuver in the darkness was not as foolhardy as it sounds. The SJ radar was very sensitive, and by coming to a course 170° to the left of the moon's azimuth, I knew that I had the mine on the port hand and could pull clear to the right with no danger if unable to locate the mine. It was my intention to silhouette the mine in the moon and sink it with gun fire. SJ radar picked up the mine at range 1000 yards, but as soon as I had maneuvered it into the moonstreak, the moon became obscured by low clouds on the horizon. Resumed course and speed, maneuvering to avoid floating objects.
2352 I SJ contact 2400 yards, closing rapidly, crossed astern, lost at 2250 yards. Believed to be a bird.

17 April
0024 I Submerged to work on hydraulic plant.
0134 I Surfaced.
0614 I Sighted mine; our position Lat. 31-45 N, Long. 134-35 E. Fired at mine with .30 Cal. carbines and sub-machine guns. Hits bounced off with a noise like that of hitting the bulls-eye in a

— page 94 —
17 April (Cont.)
shooting gallery. Manned 5 inch. Decided that the mine was worth 3 rounds. First round was on deflection, but short 5 yards. Second round was on deflection and about 4 yards short. The third round was on deflection and about 2 feet short. This round was a dud and exploded when it hit the water after ricocheting. Secured the 5 inch, manned the 40 MM guns. Exploded mine with a direct 40 MM hit.

GUN ATTACK NO. 1
0748 I Lookout sighted two ships in haze, bearing 170 T. Ship contact #2. Our position Lat. 31-45°; Long. 124-35°;.. Set tracking stations. Could not get radar range on target. Maneuvered to keep them just in the haze and got up ahead. Course about 030 T from bearings and estimated ranges. Could hear no pinging; took a sounding; 17 fathoms. PCO and others looking through binoculars and high periscope were convinced the we had a large two-masted ship with one escort. The CO was unconvinced and submerged ahead of targets at 0909. Set section watch and waited for targets to show up.

0925 I JP picked up, target's screws.

0935 I Sighted target through periscope. Set battle stations. Sea was glassy. Went to silent running. Made approach. Made ready the bow tubes. Due to the glassy condition of the sea I was too economical with the periscope exposures, and ST was unable to get a range. Sighted a cable extending between the two ships. One was 3 islands, MMM, the other one was an engines-aft vessel. I was undecided about shooting torpedoes at these targets. PCO took a look for the express purpose of helping me decide and so did the Executive Officer. They were both very positive in asserting that the targets were worth torpedoes. I was still unconvinced, and let the targets go by, not because of size, but for the following reasons: (1) Did not have a good speed solution and, in fact, had no range in which I felt any confidence, (not being at all sure of the mast head height), until the first ping range of 2900 yards. (2) I had not been able to see any gun larger than an estimated 20 MM on top of the bridge of the MMM. (3) I didn't feel that the targets had any chance of getting away from us..(4) I was still mystified by the cable between the ships. Actually the MMM was towing the engines-aft, but due to the yawing of the tow, at times through the periscope they appeared to be almost abreast of each other, and I

— page 95 —
17 April (Cont.)

was not sure that they were not sweeping. JP reported two sets of screws, JK reported only one. Accordingly I had the 5 inch gun pointer take a look at the targets, got a good set-up by ST when abaft their beam, and set stations for battle surface, 5 inch and 40 MM guns.

1052 I. Surfaced 3750 yards astern of targets. It was apparent that one was towing the other. Manœuvred to keep the towing vessel (with the gun), masked by the tow. Closed the range and opened fire at 3200 yards with the 5 inch gun. Intercepted radio transmission on 500 kcs, (see radio section). Opened fire with 40MM at range about 2000 yards. 5 inch hits set tow on fire. He obviously had a cargo of oil. Great clouds of black smoke poured out and flames roared forth as if from jets. Shifted 5 inch fire to towing vessel.

1108 I. SD contact 15 miles, bogey. 2 planes. Closing slowly. An observer on the bridge thought he saw a torpedo. Towing vessel let go his tow and decided to shoot it out with us. SD contacts closed to 13 miles. The great weakness of a battle surface as we conduct it with only 1 hatch open is in getting the gun crews back down below in a hurry. Sent 40 MM crews below and turned away from towing vessel. He was now headed directly for us, making about 10 knots and was on in range with his 20 MM gun. Opened range to 3700 yards, which left his fire falling about 50 yards short. SD contacts opened to 16 miles and were lost. Manœuvred around tug while shooting slow fire with the 5 inch. A very close over put his rudder, or screws, or both, out of commission. He abandoned ship. "Be closed him and before the 5 inch shells started pounding into him at every shot, we could see that shorts he'd riddled him with shrapnel. Closed range and sank the tug with 5 inch and 40 MM fire. Then went back to the oiler and sank it with three 5 inch hits along the waterline.

Noon Position - Lat. 31-52 N, Long. 124-55 E. There were several survivors. Picked up one prisoner from each vessel, apparently both military. Picked up a second survivor from the tug, apparently a mercantile sailor. Picked up a life ring from tug with lettering CHOYO MAHU. The identity is uncertain. We took pictures, both moving and still, and I would prefer to have the damage assessment made from them. However, the available

— page 96 —
17 April (Cont.)

data is: The tug while transmitting used the call JUJV. This may be an indefinite call. The life ring was inscribed CRYO MARU SHIMONOSAKI. I questioned the mercantile prisoner and he confirmed the name CHOYO MARU for his ship and also gave the name BAISHI MARU. One of the other prisoners drew a rough picture of a tug and towed for his guard later and in English wrote KARI MARU by the tug and BAISHI MARU by the tow. Until more accurate information is available from the photographs and from the prisoners the CO's estimate of the damage is:

SUNK:

One SMC. Tug. Wooden hull with steel deck house. Possibly CHOYO MARU (EU), 2000 tons.

One SMC. Oiler. Wooden hull. Possibly BAISHI or BANSHI MARU (EU), 2000 tons.

The mercantile marine prisoner was shown a chart and indicated that the vessels were out of KELUNG for SHIMONOSAKI, without stop, and that their route was to the north of QUILPART ISLAND.

The prisoners were stripped and placed in the 5 inch magazine.

1300 I Resumed course and speed, enroute to area.
1319 I JOOD sighted 3 planes. Submerged.
1532 I Surfaced.
1551 I JOOD sighted plane. Submerged.
1646 I Surfaced.

18 April

0517 I Sighted mine. Lat. 29-05.4 N, Long. 123-32.2 E. Mine had 7 horns, 6 arranged around the outside and 1 sticking up vertically on top. Detonated mine with 40 MM fire. 34 rounds.

1137 I Submerged for trim.

Noon Position - Lat. 28-28.5 N, Long. 128-23.3 E.

1227 I Surfaced.

1808 I Sighted mine. Lat. 27-27.5 N, Long. 122-36.6 E. 4 horned type. Commenced firing with .30 Cal. carbines which rattled off the mine's case with loud pings as before. Fired 62 rounds of 40 MM with no hits. Finally exploded mine after expending 225 rounds of .50 Cal. ammunition.

1948 I Sighted a flash of light bearing 215 T. Headed over to investigate and sighted a flash again at 200 T, but could not find anything else.

19 April

0935 I Lookout sighted ship bearing 276 T. Set bottle stations surface and closed to investigate. Turned out to be a fishing sampan.

— page 97 —
19 April (Cont.)
1010 I. Sighted a second sailboat with two masts, apparently a junk.
1019 I. Fired one round of 40 MM across bow of sampan. Maneuvered in close and examined him. It was a typical Chinese fishing boat, eyes painted in the bow, oldest man at tiller, youngest and smallest at the sculling oar, one small boy hiding under deck boards, lots of yammering. Had the sampan come alongside. Chief of the Boat boarded her and found one sack of beans, a half-bushel of potatoes and one fish. Gave the occupants 5 packages of cigarettes with which they were highly pleased. Took pictures.
Moon Position - Lat. 26-06 N, Long. 121-00.5 E.
1230 I. Could not get to life ward station but raised covering plane by VHF, gave him our position and received receipt. No business.

0900 I Surfaced.
0903 I Suspicious trace on TDM, relative bearing did not change with maneuvers.
Noon Position - {DF} Lat. 25-32 N, Long. 121-04.5 E.
1255 I Commenced circling on lifeguard station.
1311 I SD contacts 30 and 52 miles, friendly. One sighted from bridge by OOD. Broken clouds, poor visibility. Worked planes by VHF. Numerous friendly planes. Sighted PBM with P-38 cover.
1649 I SD contact 6 miles, boring, closing. Submerged.
1734 I Surfaced.
1745 I SD contact 10 miles, bogey, closed to 7. Submerged.
1851 I Surfaced. Headed over to investigate HAITAN HARBOR.

24 April
0105 I Secured SD radar while approaching harbor.
0124 I Stopped. Searched HAITAN HARBOR with the 5X expanded sweep in a dense fog. All clear. Then ran north off HAITAN ISLAND about 3 miles off the beach.
0230 I Resumed SD search.
Noon Position - {DF} Lat. 25-16.3 N, Long. 120-47.1 E.
Inside restricted area.
1217 I Circling on lifeguard station.
1219 I SD contacts 12 and 16 miles, friendly. Heavy overcast. "I've made this rendezvous with the lifeguard plane by telling the plane when we could hear him pass overhead.
1250 I Sighted mine. A new and larger type. Four (4) horns with a hand hole on top. Told lifeguard plane what we were going to do and fired 43 rounds of 40 MM. The mine took two 40 MM hits before exploding. The second hit caused a puff of black smoke and a flat burst of yellow flame near the

— page 99 —
24 April (Cont.)
water with very little noise. Possibly one of those "second order" explosions. Our position Lat. 25-09.8 N, Long. 120-45.0 E.
1320 I Sighted an oil drum. Position Lat. 25-07.9 N, Long. 120-45.5 E.
1323 I Headed out of mine field.
1338 I Sighted lifeguard plane for first time.
1619 I Lookout sighted object on horizon bearing 339 T. Our position Lat. 25-20.7 N, Long. 120-48.5 E. Investigated. Turned out to be a bow of a sunken sampan. Opened range to 2800 yards and bore sighted 5 inch gun.
TORPEDO ATTACKS NOS. 1, 2 and 3.
2130 I TDM picked up pinging. Checked with JK. Bearing 110 T. Headed over to investigate. Ship contact No. 3.
2154 I SJ contacts - two ships, 115 T and 120 T, range 9,450 yards. Our position Lat. 25-42.4 N, Long. 121-15 E. Battle stations. Two sets of pinging, 15.6 kcs. Closed target. Base course 355 T, speed 11.75 knots. Larger ship was the nearer, with a smaller ship on his starboard quarter. Could make them out from the bridge at 4,000 yards range. Planned to shoot 4 torpedoes at the leading ship and 2 at the trailing ship. Set depths 2 feet. Opened outer doors, came to course for an 800' track and waited for favorable gyro angles, and about 3,000 yard torpedo runs. Accepted a sharper track in the early part of a zig toward. Just before firing, radar picked up a third ship in the formation on the starboard bow of the trailer. Tried to raise POPON with contact report. Broadcast it.
2253 I Fired 4 torpedoes forward. COD speed 4.5 knots. Gyro angles 000.5 to 001.5, average track angles, 46 P, average torpedo run 3100 yards; shifted to trailing ship. Each torpedo jumped out of the water as soon as launched and then proceeded down the range like a porpoise, alternately broaching and plunging with a rhythmic tempo. Glassy. Calm sea with haze. Decided against shooting, any more torpedoes with this depth setting. Turned right and went to flank speed. Commenced reload. The target turned left shortly after the torpedoes were due to hit and gave chase. 11.19 knots we opened him slowly. He commenced shooting with one gun at a range of about 3700 yards. Very small gun flash. At times I was unable to see the flash at all.

24 April (Cont.)
Splashes were short in the mein with the closest two felling about 40 yards from the bow and 20 yards to the starboard of the after engine room hatch. This one splashed water on us. The splashes were white and were accompanied by a deafening detection. The COD has been used for a target by probable Japanese 3.15 inch guns previously but these splashes and accompanying bursts were many times stronger and louder. This leads me to believe that the guns were of about.4.7 inch caliber. No fuzed shrapnel was fired; all shells detonated on impact. Target ceased fire with his main battery and opened up with machine guns and tractors. At this time I felt that we would be able to outrun this chap and get in another attack on his convoy. The tractors that I saw were well to port (although on in range), so I was feeling very happy about their marksmanship. The following day, however, we dug a lead slug out of the bridge rail immediately in back of where I had been standing. The target next commenced yawing 300 at a time and giving us a broadside of 2 guns. These splashes were mostly ahead. He then came left to a steady course, showing us about 800 angle-on-bow and settled down to two-gun salvoes. When he placed a salvo one hundred yards ahead of us with one splash on either bow, I decided that he was just playing with us and would soon be on. During this time tried to raise POMPON again. Submerged. Tracked target by sound, periscope and ST. Maneuvered to get ahead of him and went deep - 150 feet. There was 270 feet of water. Commenced receiving a close depth charging of 18 charges. All below us by the DCDI. Conducted evasive tactics, trying to maneuver away from two anti-submarine vessels. When it appeared that one vessel was starting in for a good run, fired an MAE beacon. This was apparently a dud. At any rate, we could not hear it on any sound gear, and it was followed by 10 more close depth charges, laid up and down our port side, ahead and astern, but all fortunately below. No major damage was experienced. The boat was shaken, conning tower was banged about, cork knocked off, light bulbs shattered, overloads knocked loose, several of the crew were converted, two sea valves backed open, and one sea valve operating gear was sheared. After this run one of the anti-submarine vessels shoved off, leaving one who was milling about on our port quarter and pining.

0031 I: Came up, to periscope depth to look over the situation. The anti-submarine vessel was there on our port quarter, about 4,000 yards, apparently lying to. The depth charging had knocked out the tuning of the ST. Made ready 3 torpedoes forward and 3 aft, depth setting 3 feet and waited for the ST to get tuned before starting in on the target. The target saved us the trouble by commencing a sweep in our direction, zigging about 60° from side to side, Ensign WALLACE and THOMAS, W.H., RTC got the ST back in commission when the range was down to 3500 yards, and there was enough light to estimate the angle on the bow when it was 15° or less. It looked for a minute or two as if we would get a nice stern shot from about 300 yards on his port beam, but the target kept swinging more and more to his left, toward us. We speeded up to 80 r.p.m. to get off his track. Target countered at once by reducing his pinging interval from the 7,000 yard scale to the 3,000 yard scale and by showing a steady 5° port angle-on-bow. We slowed to 50 r.p.m. and steadied up. Lt. PODORFAN on the TDC, did not like the gyro angles, and neither did I, but with the torpedo run down to 400 yards there wasn't much to be done about it except hold her steady and use a spread.

0056 I: Fired 3 stern torpedoes, gyro angles 235 to 228, average track angle 15° S (due to curved run of torpedo), average torpedo run 310, with target swinging slowly to his left to head directly at the periscope. I assumed that the torpedoes would make a wider and slower curve than the one set up in the TDC and spread them accordingly by periscope, the first one a full target width (as foreshortened to view) to the right, the second at the right tangent, and the third at the bull nose. With ST range 490, pulled down the scope and went to 150 feet.

0056-44 I: One explosion. Pinging and screws from target stopped. Sound tracked two torpedoes running. Commenced to come up to periscope depth. Loud noise from our own screws.

0104 I: Loud explosion from target.

0105 I: Breaking up noises in direction of target. Sound could still track two torpedoes running.

0126 I: Surfaced. Ran through oil slick. Heard the breaking up noises beneath us. Sighted many men in the water. Our position as rectified by next

fix - Lat. 26-02 N, Long.: 121-11.7 E. 78 heads were
couted in the water on one side only as we passed
through the oil slick. There were more than this
swimming. Most of them were shouting and moaning
in a melancholy manner. Picked up one prisoner. I
was in a hurry to get off after the rest of the
convoy, so did not investigate his condition before
sending him below. He was badly injured internally
and had no will to live. On the afternoon of his
being brought aboard he was questioned by the CO
and he was later questioned by the Executive Officer
and gave out the following information: Name -
ALYEEMA, 1st class petty officer, engineering branch.
(KI-KAN). His ship had no name, but was "So-kai'-te
yo-en-ju-itsi, gol", This appears with very little
doubt to be minesweeper No. 41, although the "gol"
remains unexplained. The prisoner wrote the number
41 along with several Japanese chops which will be
given to the first available language officer. He
was very insistent about pointing to the paravanes
in the pictures of minesweepers in the Recognition
Manual, although his exact ship could not be found.
Prisoner indicated on a chart that his route had
been from KEELUNG to NINGPO. The CO's best estimate
of damage inflicted is:
SUNK: AM No. 41 (EC). Approximately 1000 T.
Tried to raise POMPON again. Broadcast contact re-
port.
Set out after remainder of convoy on their base
course.
Tried to raise POMPON to tell him to patrol across
southeast approaches to NAMKWAN and that we would
run search curve to northeast. Broadcast it.
SJ interference.
APR contact 118 mcs. Indications were that this
was the POMPON. Tried to raise him. Broadcast a
signal to shift to SCR 610-A. Then tried to raise
him on the assigned frequency with this equipment.
Slowed to 10 knots to listen on JK.
SJ contact 027 T, 11,920 yards. Two pips. Battle
stations. Targets were tracking on the same base
course, 355 T. Heard echo ranging from one source
only. Set depth 3 feet and commenced end-around
to port. Target was zigging on 5 minute legs.
Pinging on 15.3 kcs, shifting between 5,000 cnd
7,000 yard scale. At range 3600 could make out
targets from bridge. The leading target was the
largest, both by radar and visually. Could get
TBT bearings out to about 4,000 yards, but could
not make out types of ships until just before firing.

25 April (Cont.)
The trailing target was about 1,000 yards on the starboard quarter of the leader. Tentatively decided upon surface attack, shooting 3 torpedoes at each target. Perhaps I was too optimistic in thinking that because the last submerged attack with a 3 foot depth setting had been successful, that the torpedoes would run properly with the 3 foot setting when fired from the surface. Asked fire control party and PCO if they had any better plan, and none was forthcoming. Perhaps the recent close depth charging, the failure of the NAE beacon, etc., had influenced me against a submerged attack. But the surface attack did appear to give the best chance of getting both targets. The targets' speed was unchanged - 11 3/4 knots. They were still zigging on 4 to 5 minute legs. Ran up their port side to get a firing position near the beam.
Lookout picked up a sailboat on the port hand. Ran by it.
Slowed to 5 knots.
Fired 3 bow tubes at leading ship. Average gyro 352. Average track 122 P. Torpedo run 3470 yards.
Fired 3 bow tubes at second ship. Average gyro 009. Average track 116 P. Torpedo run 2900 yards. Turned right and went around stern of formation. Each torpedo jumped out of the water once, right after firing. The propellers made a loud whirring sound while they were in the air, similar to a high speed sewing machine. Two of the torpedoes made wide hooks to the left. One observer on the bridge thought we had a circular run from this. I watched them, however, and they all settled down eventually on a straight course, although the initial nocks had dispersed them somewhat. Both targets continued on their present course and speed. At that time the torpedoes were due to hit the leader, a large cloud of black smoke came from his direction which totally obscured him from view for a time. They were apparently a reference in his radio. The enemy was now out of the circle of his sight. The plan. The sea was clear. I was on the time of firing. I was at a pre-set of about 3B size and I was in the middle of a previously sunk vessel. The torpedoes sank to a depth of 3,000 feet. Dawn was beginning to break out in the were scattered low rain clouds. Commenced end-around on starboard.

0648 I Abandoned chase.
0712 I Having been unable to work POMPON directly after many attempts, cleared message to POMPON through NPN telling him to take lifeguard station until we got back.

0714 I Submerged. Periscope patrol.

1357 I Sighted overturned sampan.
1431 I Sighted mine. Our position - Lat. 26-35.2 N, Long. 121-51.8 E. Usual four (4) horned type. Exploded after expending 8 rounds of .50 Cal.
1507 I Sighted floating object, proved to be a crate trussed up heavily with mine.
1535 I Sighted floating object, proved to be a rusty oil drum without any barnacles.
1639 I Sighted floating object, a mine. Our position - Lat. 26-19.5 N, Long. 121-56.1 E. Commenced firing 40 MM's at mine.
1658 I A 40 MM hit blew a large jagged hole in the top of the mine. This hole was 10 inches in diameter. Commenced firing with .50 Cal. which splashed water into the hole. The mine slowly sank.
1717 I TDM trace. Bearing remained constant as we swung ship.
1807 I Sighted mine. Our position - Lat. 26-08.5 N, Long. 121-57.2 E.
1814 I SD contact 10 miles, bogey. Closed. Lost contact. Regained at 14. Opened to 26 miles. Lost at 23. Regained at 24, faded. During this time opened fire with .50 Cal. on mine. One hit made a hole in the mine from which thin smoke came out. It is believed that other hits made holes. The mine slowly sank from view.
1921 I Sighted what was thought to be a mine. Proved to be another crate.

1745 I SD contact 25 miles, bogey. Closed to 12. Submerged.
1822 I Squeak in shelf again noted on JP. This may have been started by the depth charging, but became progressively worse throughout the patrol and reached the point where it could be heard through the hull in the after torpedo room at 65 turns. At 80 turns at periscope depth the noises by JP grew to alarming proportions. Both shafts were bad, with the starboard being markedly worse. The noise sounds like a bearing squeal, and will, I think, be tracked down to unseasoned lignum vitae. However, I don't know of any treatment for this in the area except to run at slow speed during the attack and evasion. Made mental note to do so soon next submerged approach.
1920 I Surfaced.
2041 I Flash of SJ interference bearing 000 T. This phenomenon occurred several times during patrol and could not be traced to friendly SJ, nor to an enemy radar, nor to any other source.
2135 I Fire in after torpedo room. Went to fire quarters. Stopped. Secured battery charge. Readings were being taken after the completion of the charge on the Mk. 18 torpedoes which were partially withdrawn from tubes 8 and 10. An explosion occurred in torpedo No. 99264 in tube No. 8. The battery of this torpedo burned with a very hot fire which could not be extinguished with the CO2 extinguishers. The after torpedo room was filled with a dense, suffocating smoke. The smoke lungs were totally inadequate. This left our two rescue breathing apparati and one shallow water diving mask which could be used and which thus permitted only 3 men to enter the torpedo room to fight the fire. The torpedo itself was too hot to touch. The battery was burning fiercely. The torpedo tube was warm. The Executive Officer at the scene of the fire requested permission to open the after torpedo room hatch in order to fight the fire. This was granted. An engine was located up on propulsion to clear the smoke. I was in the conning tower with a hand telephone getting my information from the maneuvering room.

— page 106 —
26 April (Cont.)

FOLEY, L.E., QM2c, was in the conning tower and had just been relieved. Quartermaster-of-the-Watch. He immediately asked my permission to go down on deck and assist in opening the after torpedo room hatch. He took the lifejacket from the conning tower, told the OOD, and went aft. After FOLEY had gone down on deck the Executive Officer asked for help from the outside in opening the hatch. The OOD was watching FOLEY and saw him having difficulty with the hatch. JOHNSON, A.G., Slc had come to the bridge to warm up for lookout. The OOD had a wrench passed up, gave this to JOHNSON and sent him aft to help FOLEY. JOHNSON carried the wrench aft, returned to the vicinity of the conning tower, told the OOD the hatch was clear except for the depth charge dags and then went back aft to further assist FOLEY. A wave washed both men over the side. JOHNSON had no 'lifejacket. I want up to the bridge at this point, marked ship's head, made a complete circle to the left and stopped. The 'fire, meanwhile was blazing with increasing intensity and was leading to thoughts of grave danger with respect to the warhead. I was fully prepared to flood the after torpedo room, even by bottoming with the hatch open if necessary. The Executive Officer requested permission to fire the torpedo. This was granted and the torpedo was fired with a propeller look, after the handhole plate, warped by the explosion, had been torn loose, and through efforts which were no less than heroic on the part of Lt. K.F. BECKMAN, KRUSENKLAUS, D.H., TM2c and GRUMPER, J.J., Slc. These efforts included working in intense heat and smoke, rigging jiggers to the torpedo which was too hot to touch, and holding the irr thumbs over the hydrogen burner hole in the torpedo tube door during firing. It is true: impossible to express my feelings in regard to the actions of these men. It is a privilege to have been their shipmate. Meanwhile on the bridge, I had two life rings tied together with an automatic floating electric lantern and tossed over the side. After the torpedo was fired, I sent the OOD down to shut the after torpedo room hatch. Resumed power steering and commenced searching in the vicinity of the life rings. We would make circles in all directions from the life rings and return to the rings for another departure. The sky was overcast, mattress about 1000 feet, obscuring the moon. There were only a few scattered whitecaps.

26 April (Cont.)
but there were many small waves which showed up black with no white crest. We had many volunteers on the bridge, listening and searching. All binoculars were in use.
2300 I SD contact 10 miles, closing. I decided to give this plane one free pass at us. He showed friendly, however, and replied to us on VHF. He was a PBM from ORINNA, using the call 55V464. We told him we were looking for two of our men in the water and he offered to help. He dropped flares which illuminated well but only when they were very close to us. He also dropped a life raft. He said that he thought his base could send another plane out in the morning, (in reply to my question), and took our message "living" the number of men and position in accordance with the standard operating procedure. This plane was very helpful. The pilot was worried for fear he had been the cause of the men going overboard. In reply to our thanks he said that it was a pleasure to help the submarines out. After the departure of the plane at 2344, I returned to the life rings and commenced a systematic search, using the DRT. Injection temperature was 74° and I refused to give up hope of recovering these men. Our searchlight did not improve our visibility, but we kept it on, sweeping about the beam as a beacon for the moon in the water.

27 April
0034 I Skies cleared, giving us bright moonlight. Decided we would not be able to see a man at more than 250 yards, and altered search accordingly. The life rings were drifting faster than us from our DRT positions. When passing by the liferings on one occasion, there was a dark shape in one of the rings. This turned out to be a bird.
0114 I Sighted object in the water. Turned out to be a wave.
0214 I An elusive TDM trace faded out.
0520 I Heard FOLEY calling us. He was utterly exhausted, and remembered nothing from this point on. Lt. (jg) "I. K. SMITH did an excellent job of keeping FOLEY in sight while we maneuvered to pick him up.
0540 I Took FOLEY on board. He reported that JOHNSON and he had been together when they went over the side, that he had helped JOHNSON take off his heavy clothing and had supported him in the water.

until about two hours before we picked him up. He and JOHNSON together had seen the ship go by twice, one time very close aboard. About two hours ago, JOHNSON had said good-bye, had slipped down off FOLEY's back and FOLEY had not seen him come up. I decided to lie to until daylight and then continue the search for JOHNSON. Had already told POMPON to rendezvous at daylight to assist in search.

0602 I SD contact 16 miles, faded; regained at 10 miles, closing. Submerged.

0835 I Sighted plane coming out of clouds. "SALLY". Angle on the bow, about 80 port. Passed us at 3 miles and continued on his way. POMPON confirmed that it was a "SALLY" but did not submerge either. Told POMPON to patrol at discretion after completing search at dark.

Noon Position - (DR) Lat. 26-00 N, Long. 121-33 E.

1217 I SD contact 8 miles, friendly. Picked up planes on SJ, worked them by VHF. This was a PBM using call "RODEO 4" and four fighters using call "PONTIAC". These planes came down under the overcast which was 500 feet from the water and took up the search. The fighters told the PBM that they were reaching the limit of fuel, but offered to stay on and search. PBM told the fighters to return and that he would stay on and search without them. The fighters replied that they needed PBM for navigation, but that they would be very glad to stay beyond their limit of fuel. The PBM apparently had bogies on his radar when he was trying to send his fighters home without him. The weather at this time was getting worse, ceiling was closing in, and the wind was gusty. It appeared to me that the planes were taking considerable risk to even attempt to fly under the overcast. In view of the weather I thanked them and told them to leave. They searched for an hour anyway and said they were only too glad to be of any assistance. We felt that we were being backed up by a pretty fine organization when these fliers came out in this stinking weather to help us.

junks with flares, came back and reported that
he could not identify them as anything but
friendly. This plane also said that he would
be in the area most of the night and to call
on him if needed.

1159 I Sighted mine. 4 horns, 2 lifting pads. Apparently new. Low in water.
Noon Position - Lat. 28-43.5 N, Long. 123-57 E.
1223 I Detonated mine with .50 Cal. fire. The JOOD claims to have heard a .50 Cal. hit bounce from the mine prior to the hit which detonated it. No one else observed this but all observers did report a delay between the activating .50 Cal. hit and the detonation. This delay was variously estimated as being up to 3 seconds and so was probably of about one second's duration. The explosion, when it occurred, was strong and scattered shrapnel well beyond us.
1530 I Sighted small lifering in water near a piece of wood. Picked up lifering. Painted light green, no marking. Our position - Lat. 28-57.9 N, Long. 123-48.9 E.

0955 I Sighted many sailboats. A large junk with sampans working out from it.
1042 I Fired one round of 40 MM across bow of junk, went alongside. Exchanged a bag of food for fish. They must have started a process of drying these fish in the sun as we had to throw them over the side.
Noon Position - Lat. 27-50 N, Long. 121-49.2 E.
2000 I Formed scouting line with POMPON.

7 May
Noon Position - Lat. 26-11 N, Long. 120-34.5 E.
1627 I Made trim dive.
1726 I Surfaced.
1854 I OOD and lookout, in fog, heard what sounded like two explosions, apparently coming from 250 T, the direction of HAITAN ISLAND. Nothing whatever was heard below decks in any compartment. Stopped, listened on JK. Headed over on that bearing for one-half hour. No reoccurrence. Resumed course and speed.
2000 I In scouting line with POMPON.
2124 I TDM commenced acting jittery. Straight line trades would show up but would remain on the same bearing as we swung ship. We could not verify any of the TDM phenomena with the JK.
2135 I SD contact 14 miles, bogey. Closed to 8. Submerged.
2200 I Surfaced.
2317 I APR contact 160 mcs.
2350 I Commenced swinging ship at one-third speed, steadying up at every 450 change of head. Checked APR signal and found no appreciable difference in signal strength.

8 May
0225 I SJ operator had a momentary pip as he swept by bearing 000 T at a range of 8 to 10,000 yards. Swept carefully on same bearing and could not regain contact. Changed course to 000 T, ran for 2 miles and then searched in a small parallelogram. No contact by sound, radar, or APR.

8 May (Cont.)
0330 I Swingship to investigate 150 mc. APR contact.
No results.
0636 I Submerged for periscope petrol off HAITAN ISLAND, north of TURNABOUT ISLAND. Sighted numerous fishing sampans and nothing else. Two of these fishing boats sighted the periscope when they passed close aboard; one of them decided to retrieve it from the water and made two passes at the scope, one with a boat hook and one by a man leaning out of the bow of the sampan. Our pink periscope camouflage is apparently better than I had thought.
Noon Position - (DR) Lat. 26-36.5N, Long. 119-59.3E.
1926 I Surfaced. Formed scouting line with POMPON.
2028 I Sighted searchlight beams on clouds from direction of FCFMOSA. This continued for over an hour.

9 May
0032 I SD contact 19 miles, bogey. Closed to 8 miles.
Submerged.
0119 I Surfaced.
0500 I SD contact 17 miles. Friendly. Did not reply to VHF. Closed to 5 miles, submerged.
0535 I Surfaced.
0758 I Submerged for patrol off HAITAN ISLAND. Numerous fishing boats but none so close as yesterday. Had a good look in HAITAN BAY and along the beach. All clear.
Noon Position - Lat. 25-30 N, Long. 120-00 E.
1900 I Surfaced. Found fish net and line draped over boat. Made them up into a bundle.
1935 I Closed nearest fishing sampan and called him alongside. Passed over net and line. Hoped he would return them to the owner, but it was apparent that our contribution was accepted as a gift. This was also the best gift we had made to any Chinaman yet. The fishermen were all smiles and chased us for several minutes when we shoved off, attempting to give us their fish.
1946 I Circling a fishing sampan without sails. This was a good example of how imagination lends color to reports. While we had been returning the fish net, the high periscope had picked up this sampan and had reported it as a power boat. One officer, the CQM and a QM2c had agreed that the boat was "definitely under power". It had even been reported as similar in appearance to a Navy motor launch. Upon closing to investigate, of course, it turned out to be the typical fishing

sampan, mast not stepped, sculling cars, eyes in bow, and all. Returned to scouting line in FOMOSA STRAIT.
2255 I Swung ship to investigate APR contact at 220 mcs. No results. This interference disappeared. Believed to have been airborne.

10 May
0206 I Challenged by POMPON on SJ.

2258 I Surfaced.

11 May
0040 I First of several floating objects on SJ radar.
0610 I Set course into blind bombing zone for lifeguard station.
0735 I On lifeguard station. Heavy overcast.
1025 I SD contact 22 miles, friendly. Raised lifeguard plane on VHF and directed him to our position at the edge of the overcast.
1042 I Sight contact with PBY. No business.
1158 I Submerged to clear blind bombing zone. Periscope patrol.
Noon Position - Lat. 24-52.5 N, Long. 120-20.5 E.
1519 I Broached in heavy sea.
1530 I Surfaced.

12 May
0159 I Took over POMPON's lifeguard station for remainder of patrol, telling him to work the area at discretion.
0643 I Submerged. Periscope patrol. Depth control difficult due to swells.
Noon Position - (DR) Lat. 25-47.9 N, Long. 121-01.9 E.
1850 I Surfaced. Mountains of northern FOMOSA visible at 40 miles. This clearest weather we have had in the area.
2111 I Observed searchlight drill on FOMOSA.
2259 I OOD, J00D and lookout sighted green flare with orange tail, bearing 090 T. Headed over to investigate. Listened on JK.
2321 I SD contact 8 miles, closing. Bogey. Submerged. This flare was explained.

Noon Position - (DR) Lat. 25-43.2 N, Long. 121-31.8 E.
1727 I  At 55 feet 00D sighted object which he thought
    was a periscope, bearing 132 T.  This was allegedly
    complete with feather.
1733 I  I sighted the alleged periscope but with a more
    judicious length of own periscope exposed.  The
    alleged feather was on the opposite side from
    that originally reported.  This object did not
    form a silhouette against the sky as a submerged
    periscope should and does, with the proper amount
    of own periscope exposed.  The sea was calm with
    an easy swell and an occasional whitecap.  All
    clear by sound.  Headed over to investigate on
    last bearing.
1842 I  Reversed course.
1845 I  00D (a new one), sighted what he thought was a
    piece of wood with a bird sitting on it.
1925 I  Surfaced.  Went close aboard of object with bird
    on it.  This was a peer shaped object similar
    to an airplane belly tank or wing-tip float.  It
    was probably the "periscope".
2120 I  Forward torpedo room and conning tower heard
    what sounded like distant explosions.  These
    are believed to have come from misalignment or
    other disarrangement of the Q3-TDM head.
2130 I  Set course for lifeguard station.

15 May
0112 I  Observed searchlight drill on FORMOSA.
0259 I  Searchlight display.
0810 I  SD contact 11-miles, bogey, closing to 8.  Submerged.  Set course in the blind bombing zone for
    lifeguard station.
1017 I  Surfaced.

— page 117 —
15 May (Cont.)
1150 I Heard first of several rumbling explosions from direction of FONOSA, 20 miles away. Probably due to our strikes.
1151 I On lifeguard station. SD contacts, 28 and 32 miles, friendly. Faded.
Noon Position - Lat. 24-58.9 N, Long. 120-27.3 E.
1422 I Submerged. Headed out of blind bombing zone.
1552 I Surfaced. Headed over for western side of FONOSA STRAIT.
2023 I SD contact 7 miles, bogey. Submerged.
2109 I Surfaced.
2203 I Observed strange pip on "A" scope of SJ. At a range of about 6000 yards there was a persistent pip on a steady true bearing, which stayed on the screen no matter what our heading. The pip for the most part remained at a constant height of about 4 inch. Occasionally, however, it would rise to saturation. It was 900 yards wide and plotted by rough check as stationery. The most peculiar feature was that the pip was fuzzy at all times on both sides and on the top. The sky was absolutely clear with no clouds, and with a quarter-moon at about 170 degrees from the bearing of the pip.
2215 I After everyone had a look at the pip and couldn't make anything out of it, we went to tracking stations and started an end-around on the pip, intending to get it up-moon and look at its source. The pip immediately disappeared. We ran through its former position and found nothing.
2300 I SD contact 6 miles, closing. Bogey. Submerged.

16 May
0013 I Surfaced.
0659 I Submerged. Periscope patrol off LAMYIT, working up toward TURN-BOUT.
Noon Position - (DR) Lat. 25-00.9 N, Long. 119-32.5 E.
1530 I Observed object through periscope, was not well seen, might possibly have been a mine. Attempted to copy 8KC lifeguard sked on SD antenna. Could hear NPN and other stations but was unable to hear 8KC.
1917 I Surfaced.
2000 I SJ interference bearing 078 T. The radar officer was sure that we had a Japanese 10 centimeter radar at this point. We had built up a little reserve of fuel so I decided to chase this will-o'-the-wisp. We maintained a search on the SJ radar, and would break off from this and listen on the SJ at frequent intervals. The interference

— page 118 —
16 May (Cont.)

remained on the same true bearing and kept growing weaker as we drew closer. There was no land on this bearing. After remaining steady for 2 hours the bearing of the interference drifted to the right to 100 T, where it remained for the rest of the night. At 0145 SJ interference was picked up from another source, bearing 260 T. This bearing too, remained constant for the remainder of the night despite our maneuvers of steaming in a square in the middle of FORMOSA STRAIT. My conclusion is that interference on the SJ radar does not necessarily indicate another SJ, nor even another 10 centimeter radar. I believe that we have quite a bit to learn about skip distances, harmonics, refraction, reflections, side lobes, back lobes, and general atmospheric conditions in connection with this radar. During the night, APR contacts were noted on the following frequencies: 200, 203, 222, 230, 226, 160, 164 mcs.

17 May
0049 I Brief searchlight display from FORMOSA.
0704 I SD contact 6 miles, submerged.
0854 I Sighted three-masted junk bearing 180 T. He was right on our lifeguard station.
0908 I Surfaced. Manned 40 MM and .50 Cal. guns and started in to investigate junk. It was a fairly large three-master with no markings nor pennants nor paint of any kind except for the eyes in the bow. Circled him and looked him over. He was making 4 knots with the wind headed for FORMOSA. Position: Lat. 25-09.5 N, Long. 120-40.3 E, which is a point 20 miles off the FORMOSA west coast. His course and speed thus aroused my suspicions. In over a month in the area this was the first time that we had seen a junk of this size, this far from the CHINA coast.
0952 I Fired two 40 MM shells across bow of junk. The junk made no attempt to lower his sails, but maintained his course and speed.
0957 I Shot down mainsail. He still made no attempt to lower his other sails. Shot down all sails. No other damage was done. Went close aboard junk, told the occupants to get into the sampan. They launched the sampan readily enough, but only half the crew of 14 threw in a few personal belongings and jumped in. They sculled over and came along-side of us and swarmed aboard like flies. They were happy to be aboard. We managed to keep them all from getting out of the sampan and to put some

— page 119 —
17 May (Cont.)
back in and sent it back to the junk. This left about 3 Chinamen on board. Went alongside junk. About 4 more Chinamen jumped right aboard the submarine. Pulled clear from junk and directed rest of crew by megaphone to man the sampen. They thought they were all being invited over to the submarine so they climbed into the sampen without delay and came alongside. We had the boarding party down on deck waiting for them this time. Took their painter and secured it, and by threats with guns and main force, prevented the occupants from boarding us. We then forced all 14 Chinamen to get into the sampan with their bags and baggage. This was a feat of no mean suasion on the part of the Chief of the Boat. Those who were on board went to their knees and protested while those who were in the sampan joined them in moaning and sighing. We finally got them all loaded. The sampan, although it was taking water over the gunnels from time to time, was in no danger of sinking. The occupants protested, however. While we kept the sampan secured alongside to starboard with a guard with a carbine keeping the occupants in their places, we went alongside the junk and secured it alongside to port. Boarding party examined it thoroughly. It had a small amount of fish, very little fishing tackle, about 3 bags of rice, a few papers, one suitcase of fairly good civilian clothes, but nothing more suspicious. The papers will be turned over to the language officer. It now appeared that the junk might be actually engaged in the fishing trade. His movements were still unexplained but it was obvious that he was not carrying cargo for the enemy. Decided not to sink the junk. Cast loose both junk and sampan. Told the middle-aged leader of the group to head west, not east, and backed clear. Gave them a gunny sack full of canned food and a whole carton of cigarettes, which should more than make up for the holes in their sails and the damage to their halyards.

1121 I SD contact 20 miles, friendly. Never sighted this plane but talked to him on VHF. He was not our cover.

1137 I SD contact 19 miles, bogey, closing, and by the rate of closing, apparently headed right for us. SD contact 27 miles, friendly, closing, at the same time. We were working one plane

— page 120 —
17 May (Cont.)
on the VHF at this time but did not know whether it was the bogey or the friendly. The bogey kept coming right in.
1142 I Sighted plane, position angle 40, nearly up-sun, angle on bow abcut 10. Range 4 miles. This plane had 4 engines but neither the OOD nor myself could see any other friendly characteristics. Tail and fuselage were not visible. Submerged. On the way down "JUKEBOX ONE" informed us that he should now be about 3 miles southeast of us. Assumed that "JUKEBOX ONE", (who was our B-17 cover) was the bogey that we had just sighted. Went to periscope depth and searched for him. He was not visible. This was the only ill-mannered plane that we had yet encountered. All the time we were down he hovered overhead so that we were not able to see him. I finally realized that this what he was doing. Raised the SD mast and immediately got the plane at 4 miles. Came up to 46 feet and raised him on the VHF. Asked him to make his cockerel crow and to keep it crowing while he was near us. He did. We surfaced. The plane said that he had a report that a B-25 was in trouble at 34 GOLDEN GATE 21(sic). We finally got settled that 34 GOLDEN GATE 021 was the place to search. "JUKEBOX ONE" said that he would make a brief search and come back and let us know. We set course for the spot in question.
Noon Position - Lat. 25-23.5 N, Long. 120-48 E.
1305 I Sighted plane, 4 engines, position angle 50, about 10 miles, headed directly for us. Called "JUKEBOX ONE" on VHF and asked him to turn on his IFF again. He did. He was the plane in sight. He reported negative results of his search. We continued on to the spot and on the afternoon sked received word that no plane was down.
1819 I SD contact 15 miles, bogey. Closed to 10. Sighted from bridge a formation of one bomber and about seven fighters headed south for FORMOSA. Submerged.
1915 I Surfaced. Sighted floating object. Headed over to investigate.
1926 I Lookout sighted "BETTY" about 15 miles, headed south for FORMOSA.
1934 I Lookout sighted second "BETTY" about 10 miles, headed south for FORMOSA.
1938 I Floating object identified as metallic object almost a cube in shape, about 4 feet on a side. Very similar in appearance to a pontoon of type used in making up our pontoon barges.

17 May (Cont.)
1930 I Copied LUZON sked which included no lifeguard for us for tomorrow. Had tried to raise MUSKAL-LUNGE unsuccessfully to determine his STA at the lifeguard station, but now decided that since he was due on the 18th and there was no business scheduled for that day, that, even if he were delayed 24 hours he would be in plenty of time. There was very little prospect of the lifeguard station being left unguarded. Set course out of area in accordance with orders already received from ComSubPac.
2000 I SD contact 15 miles, bogey. Closed to 10, sighted from bridge. Angle on bow 10. Submerged.

18 May
0515 I SD contact 5 miles, closing. Submerged. Lost power on stern planes.
0612 I Surfaced. Set course north along China coast for search by daylight of the area which has now become blind bombing by night. Sighted many junks.
0730 I Circled close aboard junk #11704. He doused his sails at our approach. All hands showed considerable alarm until we broke out the colors, at which the occupants smiled and waved at us.
0740 I Flying flag for junk #9407. Sighted more junks during morning but did not investigate any more of them closely.
1150 I Decoded orders from ComSubPac, directing COD and MUSKAL-LUNGE to rendezvous in vicinity of 32 N - 126 E to transfer PCO from COD to MUSKAL-LUNGE to assume command and to transfer CO of MUSKAL-LUNGE, who was ill, to COD, for further transfer to GUAM.
Noon Position - (DR) Lat. 27-38:8 N, Long. 121-35.8 E.
1215 I Commenced first of several attempts to raise MUSKAL-LUNGE on area frequency to arrange time of rendezvous.
2114 I Decoded 5th Air Force request for lifeguard submarine on 19 May. There was nothing we could do about this and the information was available to ComSubPac.
2130 I Worked MUSKAL-LUNGE. From his reply it was apparent that he had not received the orders to the rendezvous. Referred him to the message. In reply received request for rendezvous closer to base. Assigned new rendezvous at Lat. 32-23 N, Long. 127-30 E. This rendezvous was as far east as I thought it advisable to prescribe

— page 122 —
18 May (Cont.)
and still be in the open sea west of DANJO GUNTO.
Asked MUSKALLUNGE whether he was proceeding on
surface, and held in abeyance the matter of
shifting the rendezvous to the south of DANJO
GUNTO. MUSKALLUNGE replied that he was proceeding
submerged on the 20th but would try to run surface
thereafter.

19 May
0405 I Immediately upon changing the location of the
rendezvous which had been designated by ComSubPac,
I sent a 'message to ComSubPac informing him of
the new location and of my estimated time of arrival.
I did this 'because the MUSKALLUNGE was in commu-
nication with ComSubPac and was sending him
information without making it available to me.
Communications between the MUSKALLUNGE and COD
had not been reliable. My experience with rendez-
vous has shown that it is best to keep all parties
concerned fully informed.

0430 I Decoded message from ComAir OKINAWA telling sub-
marines in vicinity of Lat. 32, Long. 127 to be
alert for planes in trouble during the after-
noon of the 19th. Apparently a strike at the
KOREAN coast. Sent message to OKINAWA telling
them our estimated noon position, course, and
speed, and volunteering to serve as lifeguard.

0806 I Sent message to ComSubPac telling him all avail-
able information that I had obtained from the
MUSKALLUNGE with my plans for rendezvous.

0910 I SD contact 7 miles, bogey. Submerged. Rain
and general poor visibility all day today.

0935 I Surfaced.
Noon Position - (DR) Lat. 31-14.8 N, Long. 125-13.1 E.
1254 I SD contact 23 miles, friendly. Worked him on
VHF. No targets.

1934 I Decoded message from radio OKINAWA saying the
strike had been delayed until the 20th.

20 May
0034 I Worked MUSKALUNGE, getting his position, course,
speed and estimated time of arrival at rendezvous
of 0200 I on the 21st. A plot showed that he was
intending to run submerged on the 20th. This
factor ruled out a rendezvous south of DANJO
GUNTO. Accordingly I did not change the rendez-
vous and sent a message to OKINAWA telling them
we would be in the rendezvous position on 20 May
and would like to lifeguard.

20 May (Cont.)
0245 I Exchanged calls with SEGUNDO by SJ.
0804 I Arrived at rendezvous station. Ran a short line up towards QUELPART ISLAND during the day and returned.
Noon Position - Lat. 32-41.1 N, Long. 127-26 E.
1245 I Lookout sighted two planes, distance 4 miles, apparently Coronados. Submerged.
1319 I Surfaced.
2239 I Exchanged signals with MUSKALLUNGE by SJ radar.
2329 I SJ contact on MUSKALLUNGE. Worked him by VHF. Ascertained that CO would be able to make trip in rubber boat. Fairly heavy seas. Had MUSKALLUNGE lie to and pump oil while we circled him, spreading oil.

21 May
0040 I Cast loose rubber boat containing Comdr. W. H. LAWRENCE, 73367, USN with SOP orders to assume command of MUSKALLUNGE and with Lt. HURST as Cox. Spread 5 more gallons of oil from the Forward Torpedo Room head, backed clear, and withdrew to leeward. Sent MUSKALLUNGE in to recover boat.
0110 I MUSKALLUNGE received boat alongside.
0116 I MUSKALLUNGE east loose boat and pulled clear to windward. Commenced maneuvering to recover boat. The oil slick proved reasonably effective in keeping the waves from breaking. Lt. HURST reported that his chief difficulty came from the fish nudging him through the bottom of the boat. He turned off his light for a short time when this happened but turned it on again as soon as we started playing the searchlight.
0150 I Recovered boat and occupants, taking aboard Lt. Comdr. L. A. LAJAUNIE, Jr., 78819 USN., the former CO of the MUSKALLUNGE.
0155 I MUSKALLUNGE departed on patrol. We set course for GUAM.
Noon Position - Lat. 31-19.7 N, Long. 128-58 E.
We had been experiencing squally weather all day with wind and sea from the northeast, gradually veering to eastward, and with a falling barometer. When the barometer dropped 0.30 inch in one hour, it was apparent that we were in the northeast quadrant of a cyclonic storm. At 1600 the barometer steadied at 29.60 inches. The winds decreased in intensity and rapidly veered to southwest, and for a short period we had an almost calm sea with a slight up and down movement and the sun shining overhead.

— page 124 —
21 May (Cont.)
By 1700 wind and sea had commenced picking up again from the southwest as we passed the storm center.
2124 I Commenced uneventful transit of the NANSEI SHOTO using the passage, south of AKUSEKI JIMA. Our control of the air was well demonstrated. I had judged that the weather was too poor for any plane contacts this night. In actuality we had no enemy plane contacts and had one contact with an OKINAWA-based search plane. After receiving his report of no targets we told him about the typhoon to the north-westward. He replied that he knew about it since he had been flying around in it for the past 3 hours. I doubt that the American public will ever fully realise the risk and hardships involved in the non-glamorous aspects of the air war.

22 May
0515 I Submerged. Unable to maintain depth control at periscope depth. Commenced watering batteries and making routine repairs.

24 May (Cont.)
1655 K Intercepted message from a plane to AGATE BASE telling of 3 Corsairs last seen 75 miles from our position. Raised AGATE BASE and offered to help in the search. AGATE BASE did not understand our Victor call, so we had to explain to him that we were a submarine. He replied that he could use us the next day, told us to stay in the joint zone and that the Dumbo planes would contact us in the morning. Sent message to ComSubPac advising him that we were doing this.
2041 K Conducted battery discharge at 6-hour rate.

25 May
0155 K Received messages from ComSubPac and ComTask Group 17.7 permitting us to search a 90-mile square surround in the reported position, and informing us that an emergency submarine notice had been issued to cover us. Entered air-surface zone and commenced search. Reported our movements to AGATE BASE as soon as he came up on the lifeguard frequency in the morning. Sighted Dumbo. Worked them by VHF and on lifeguard frequency.
Noon Position - Lat. 25-47.3 N, Long. 138-30.3 E.
1932 K Sunset. Discontinued search. Returned to Joint zone and resumed course for GAM.

we were at 200 feet with the ventilation running when the bomb exploded. As we proceeded further westward we had more contacts the same day and throughout the transit.

No new tactics were encountered.

On only one occasion did we encounter bad manners on the part of a friendly plane. The difficulty arose, ironically enough, with a JUGO E-17 U.S. JUKBOX ONE) who was our air cover on a illegal mission. It was apparent that he just didn't know her better than to close right in on us from up-sun with his BK secured, and then, after driving us down, no hover directly overhead. (See narrative for 17 May.) This was in marked contrast to the behavior of sl other IUZON planes, OKINAWA planes, and MAKAIAS planes encountered east of the NANSEN SHOTO. We found it very easy to exchange information with most of them by VHF.

It is indeed a privilege and a pleasure to witness the feats of skill and airmanship which are apparently routine with the search squadrons based on OKINAWA.

U.S.S. COD (SS224) GUN ATTACK NO. 1 PATROL NO. 6
Time 1101 I Date 17 April 1945 Lat. 31-51.5 N.
Long. 124-51.5 E.
Target Data - DAMAGE INFLICTED
SHIPS SUNK: One tug, possibly CHUYO MARU
One loaded wooden oiler.
DAMAGED OR PROBABLY SUNK:
DAMAGE DETERMINED BY: Observed to sink.

DETAILS OF ACTION
USED: (1) 5"25 cal. gun; Expended 69 rounds, fuzed HC.
(2) 40 MM guns; 316 rounds expended.

Surfaced astern of tug with tow at range of 3750 yards. Closed range, maneuvering to keep tow between COD and tug, to 3200 yards and opened fire with 5" gun. Third round struck in waist of oiler and a great ball of flame enveloped the midship section of the ship, followed by dense clouds of black smoke rising immediately. Abcut 17 more rounds were fired rapidly and approximately 90% were observed to hit the forecastle, poop, and sides, sending new sheets of flame aloft and a pall of oil smoke several hundred feet high, enveloping the target. Tug had meanwhile cast loose the tow and placed herself in protected position with oiler between COD and herself, at the same time attempting to clear the area. COD speeded up, closed oiler, raking entire length with 40 MM fire, and opened fire on tug. Crews of tug and oiler were observed mounting and manning machine guns at this time, many splashes around COD.

First seven to ten rounds were observed to fall close aboard tug, who at this time was swerving wildly from side to side, finally presenting a zero angle on bow to COD. Tug was firing at COD with 20 MM or heavy Hotchkiss gun mounted on wheelhouse and two other guns, when a near miss on tug's starboard side caused her to lose steerage way and steering. Sharp turn to her port and marked reduction in speed indicated this as she presented 90 starboard angle on bow. Crew of tug abandoned ship. At this time target was observed to be completely riddled by fragments from H.E. shells.

U.S.S. COD (SS224).

ATTACK DATA (Cont.)

The metal superstructure was shredded and from the vicinity of the engine room arose many small streamers of smoke. Several hits were observed on various parts of the vessel further rendering the deck houses and hull. 40 MM opened up on tug at this time, raking hull and 5" put several rounds in the engine rooms: starting 'additional fires and causing several violent explosions believed to be boilers. COD closed to 2000 yards putting several rounds in waterline which sent ship to the bottom.

Closed oiler to about 500 yards, firing into hull along waterline on side and stern, causing it to sink. During this firing several bright flashes were noticed amidships followed by sheets and jets of flame. As the oiler sank, drums which were on deck floated off into the water and the crackling and popping noises continued for some time.

While at MAKE ISLAND we adopted the 5" fire control system which had been promulgated by Comdr. D. C. WHITE. This consists of telephone control from the conning tower, with control and spotting officer on a periscope. Target is kept set up on TDC, using gun as a range finder after initial salvo. Range spots are by SJ radar. Every 40-yard increment is sent to the gun. The system has many advantages. The control party is behind armor in the conning tower in relative quiet, yet in easy communication with C.O. on the bridge by 7 MC. The gunnery officer on the periscope shears is free to control all rapid fire guns by voice. The executive officer at the other periscope is free to watch all targets and pick up any item being overlooked by the commanding officer.

In an effort to simplify ammunition stowage and supply, this vessel mounted the following secondary guns for this patrol: Two 40 MM, four .50 cal., zero 20 MM. This decision was made against the advice of the force gunnery officer, who pointed out that the 20 MM is a more reliable gun than the 40 MM. It required most of our training period to learn about the 40, especially to find the best weight and amount of grease to be used. The guns during this patrol were thoroughly reliable and their performance is a fitting tribute to the industry and attention to duty of Lieut. Charles PODOREAN and ALDRIDGE, J. E., GM2c.

1. ANTISUBMARINE MEASURES AND EVASION TACTICS
2. During attack No. 2, (the submerged attack on AM #41), the target was using a modulated signal with automatic keying, shortening range scale as the range closed. He continuously shortened the keying interval as the range closed under 800 yards, indicating the use of equipment similar to the chemical range recorder of our own A/S vessels. The frequency of his equipment and that of the PC in company was 15.6 kcs. During attack No. 3 a zero beat was obtained on the same PC at 15.3 kcs.

Evasion tactics consisted of steering a continuously curving course at 50 r.p.m., running silent at 150 feet with depth of water 270 feet. Serious damage was avoided by reason of the depth setting of the charges, which were all too deep. We could have done a much better job of avoiding the first depth charge attack. "Then it was apparent that one A/S vessel was starting in for a good run on the second depth charge attack, we fired an MA5 beacon and speeded up The MA5 beacon was a dud, as had been the one which we fired during the training period at PEARL.

(K) MAJOR DEFECTS AND DAMAGE

HULL AND MACHINERY
QB The QB sound head installation as presently connected with the TDM is unsatisfactory. The high speed training of the QB head has caused noticeable wear on the shaft, which in turn, creates excessive vibration due to the increased clearances. The vibration keeps the hydraulic lines to the sound head loose.
There is present in the QB sound head installation a pounding noise, the cause of which is unknown. The fault may be with a loose spider and drum or the outer door.

SHAFTS The starboard shaft has a squeal when running at speeds of 65 r.p.m. higher. The intensity of this squeal has progressively increased throughout the patrol. Investigation has revealed no abnormal high temperatures at the stern tube bearing. The squeal may originate in the strut or possibly the stern tube bearing and its frequency is one per revolution. A lesser noise is present in the port shaft.

HYDRAULIC SYSTEM The hydraulic plant acquired a pounding noise in the accumulator. This defect was traced to faulty packing. Upon disassembly the leather packing was found hard and dry despite proper maintenance. The oil side was repacked and the shaft stoned. This eliminated

1. MAJOR DEFECTS AND DAMAGE (Cont.)
2. #1 EVAPORATOR Due to a leaky vapor seal, the complete compressor was replaced with a spare by the tender repair force. After 6 hours operation a leak developed on the pulley end and was renewed by parts from ship's spares.

MASTER: GYRO COMPASS The follow-up system of the meter gyro was out of commission twice during this patrol. On 18 April, the left hand vacuum tube failed causing all the repeaters to be out of commission. The faulty tube was replaced and the gyro was placed back in commission. On 12 May the bakelite drum holding the automatic speed correction slip rings short circuited due to carbon dust and dirt. The drum was removed, cleaned with alcohol, scraped, built up with sealing wax and replaced.

HEAD SEA VALVES During the depth charge attack on 24 April the first string of charges was of such intensity as to cause the discharge sea and stop valves in the officers' head to open violently; the sea valve operating handwheel was observed to spin rapidly and the stop valve operating lever was thrown to the open position with such force as to shear the pin joining the hand lever to the vertical operating shaft. Fortunately this was detected immediately by personnel in the forward torpedo room and the sea valve was shut after having taken enough water aboard to fill the bowl and run several inches on deck. The stop valve was shut with difficulty by using a wrench, and the sheared pin was removed and replaced.

During our overhaul at MARE ISLAND a job order had been issued to remove this opening in the hull by running the head discharge into the No. 1 Sanitary Tank. The job was cancelled by the yard without reference to the ship, but with the approval of certain administrative officers who have never been depth charged. At this stage of the war priority of submarines for overhaul is low. It is recommended, therefore, that the delays in overhaul schedules be accepted in order to accomplish all essential work.

TORPEDO / AND GUNNEFY

Four hydrogen burner casualties were experienced during this patrol, three being the result of voltage surge when I.C. motor generator speed regulator failed to function.

No grounds were noted on any of the torpedoes and no dead cells were located.

A major torpedo casualty occurred on the 26 of April. A hydrogen explosion in torpedo #99264 started a battery fire and also detonated hydrogen in torpedo #99218.

— page 138 —

3. which resulted in damage or destruction of 75% of its cell caps. A careful check was made of #99218 but no further damage noted. Ruptured cell caps were replaced by rubber gloves.
4. Torpedo #99264 was fired from #8 tube with propeller lock in place and with stop valve shut. The great heat of battery fire and resulting smoke made this necessary for the safety of the ship.
5. At this point this ship would like to point out the inadequacy of the present submarine allowance of the rescue breathing apparati. The old type smoke canister, as every one knows, is of no value whatsoever. At PERIL HARBOR this ship attempted to draw four of the Rescue Breathers but only two could be obtained. (The ship's allowance). Thus, when this fire occurred as a result of the torpedo battery explosion, only two rescue breathing apparati were available (one at each end of the ship), and only two men could work in the compartment, plus one other wearing a shallow water diving mask.
6. At one time a smoke canister and lung was authorized for each compartment. It would seem to follow, therefore, that a rescue breathing apparatus should be authorized for each compartment on the ship. This change is recommended for submarine allowances.
7. Investigation indicates that the explosion occurred as a result of hydrogen accumulation during charge. The battery charge had been completed on #99264 and #99218 torpedoes, readings had been taken on #99264 and hand hole covers replaced. When the charging cable was removed from #99264, a spark resulted, flashing through to battery compartment and causing hydrogen explosion. Number 7 held holes cover was blown off and an intense battery fire was started. The hydrogen in the room and in #99218 was detonated as the hand hole covers had not yet been replaced on this torpedo.
8. It is highly recommended that during charge, Mk. 18 torpedoes be ventilated continuously, using low pressure air through ventilation plug with at least two hand hole covers off. No exhaust lines in ship's ventilation system except at the torpedo room bulkheads makes for high concentration and accumulation of hydrogen gas in the torpedo rooms, especially around the torpedo tubes. This boat now has portable blowers rigged for exhausting this gas. Tests with portable hydrogen detector indicate that an explosive mixture exists at nearly all times in the torpedo

(M) RADAR

COD carried a specially trained radar officer for the
first time on this patrol. This came about at GUAM when
JOHN WALLACE, CRT(A/A) received his commission as Ensign.
The performance of the radars during patrol, naturally,
was commensurately improved. Less than one hour was lost
on the SJ and about 3 hours were lost on the SD.
Troubles experienced were: Routine tube failures,
fuse failures due to fluctuations of line voltage, a
break in the flexible cable drive to the PPI unit of the
SJ, and a short in the high voltage winding of the pwer
supply transformer of the BN. The winding burned out
and had to be removed. High voltage for the BN was then
obtained from a spore SD radar high voltage transformer
which had to be stepped down from 18,000 volts to 4,500
volts by means of a resistance net work. The BN gave
satisfactory performance for the remainder of the patrol.
During this patrol, as in previous ones, the SD radar
was keyed for a brief period every 30 seconds, day and
night. It is my opinion that no planes were attracted
by this.

(N) SONAR GEAR AND SOUND CONDITIONS

Sound conditions were average and performance of material
normal except as noted.

I was unable to detect any difference in performance on the part of personnel that could be attributed to the effects of our visit to the United States. Everyone seemed just as aggressive and the commanding officer was just as stupidly willing as ever to let the Japanese use us for a target.

— page 145 —
3) PERSONNEL (Cont.)

STUART, D.J., SL, USNR was received at MARE ISLAND. He is a recent graduate of the West Coast Sound School, without previous experience at sea. He was given a battle station on the JK. His performance was worthy of a veteran and reflects great credit on the Sound School. He was absolutely reliable and unperturbed during the most trying conditions. Most striking to me was his ability to give accurate range estimates from the sound of the target screws alone. All hands received a great deal of benefit from the ship's week of services to the same school. Instruction was given us both on shore and on board. I believe that all prospective submarine commanding officers would profit from a course of instruction in the surface ASW school.

During this patrol, for the first time, I encountered a Naval Academy graduate whose goal was to attain a 2.5 in the theatre of war. 2.5 is not passing with me. This is a game for experts. To raise a man's sights from 2.5 to 4.0 entails a shift of 60% in his point of aim. Making that snift is tantamount to acquiring a new philosophy of life. The process is painful.

I would like to recommend that the Executive Officer of a fleet submarine on war patrol, if he be in the grade of lieutenant, be issued a spot promotion to lieutenant commander. The billet is one of considerable responsibility; the officer holding it is in training for command.

1. Radio: The usual enemy countermeasures, keyed and unkeyed CW and "hcwler" jamming, were heard on all circuits continuously, but, with a few exceptions, were more bothersome than effective. On at least three occasions 8KC (LUZON) was completely blocked out by unkeyed CW jamming. Jamming on the fundamental and secondary harmonic of the ship-shore primary frequency series made it very difficult to work NPN, but NKN was very helpful on most of these occasions and was able to read us well above the intensive keyed CW used by the Japs. On one occasion while lifeguarding, channel one of the VHF was jammed with fair effectiveness by an intermittent unkeyed CW tone. There is the possibility, however, that this was interference from an enemy radar in the 140 mc band rather than intentional jamming.

2. Radar: The APR performed reliably, though no information from it was usable. Several careful attempts were made to get a directional indication from the APR by swinging ship, without success. A simple directional antenna would make the APR more useful. No attempt is made to list all of the APR contacts made on this patrol. Instead, the following list shows those contacts which we were unable to identify by means of the information furnished us. There may be some previously unrecorded signals in the lot.

Subject: U.S.S. XDD (SS224) - Report of War Patrol June 6th.

1. The sixth war patrol of the U.S.S. XDD, under the command of Commander J. A. ADKINS, U.S. NAVY, was conducted in the East China Sea, in company with the U.S.S. POMPON; both vessels participating in coordinated patrol and lifeguard operations.

2. The patrol was of six six (66) days duration, of which, thirty (30) days were spent on station. Thorough area coverage was maintained. The patrol was terminated by a dispatch from Jomsubspac. Four ship contacts were made. The first contact was on a friendly convoy while enroute from Pearl to Guam. Contact number two, a tug and tow, was developed into a successful gun attack. Contact number three on 24 April, was developed into three torpedo attacks. A properly marked enemy hospital ship was the fourth contact, and it was avoided.

3. A summary of the attacks follows:

GUN ATTACK NUMBER ONE - 17 April, 1945.

In the late morning of 17 April 1945, two ships were sighted and after carefully inspecting them, it was decided to battle surface and engage them with the deck guns. Upon surfacing, it was apparent that one vessel was towing the other. The two was engaged with 5" gunfire at a range of 3,200 yards, and with the 40 mm at a range of about 2,000 yards. 5" hits set the bow on fire. The tow obviously had a cargo of oil as great clouds of black smoke poured out and flames engulfed the vessel. The towing vessel let go his tow, and decided to shoot it out. The 40 mm crews were secured due to aircraft contacts and the towing vessel was taken under fire at a range of about 3,700 yards, and was sunk with 5" and 40 mm fire. The 30D then returned to the oiler and sank it with three five inch hits along the waterline. Three prisoners were picked up. It is estimated that the following damage was inflicted. Sunk: One (1) SKI Tug; Possibly SHOYO MARI (EU), 2,000 tons; one (1) SKI Oilers; Possibly DASHII MARU (EU), 2,000 tons.

TORPEDO ATTACK NUMBER ONE - 24 April, 1945.

On the evening of 24 April, 1945, SJ contacts were made on two ships at a range of 9,450 yards, base course 355 T. Upon closing, four Mk 16-2 torpedoes were fired from the bow; tubes at the leading ship, with depth settings at two feet, gyro angles 000.5 to 000, average track angles 46 P, torpedo run 3,100 yards. Just before firing, radar picked up a third ship in this convoy. Each torpedo jumped out of the water as soon as launched and then proceeded down the range like a porpoise, alternately breaching and plunging. No hits were obtained. The trailing ship was not fired upon considering the performance of the torpedoes at a depth setting of two feet. The target detected the COD and gave chase. The increasing accuracy of the target's gunfire forced the COD to submerge and a severe depth charging followed.

TORPEDO ATTACK NUMBER TWO - 25 April, 1945.

Upon coming to periscope depth after torpedo attack number one, the same target was observed on the port quarter, range about 4,000 yards, apparently lying to. The previous depth charging had knocked out the tuning of the 5T. The target commenced a sweep in the direction of the 30D, which terminated when COD fired three stern tubes with gyro angles 235 to 228, average track angle 150 S, depth setting three feet, average torpedo run 310 yards. With range 490, COD submerged to 150 feet. One explosion was heard which stopped pinning and target screws. Upon surfacing, COD passed through an oil slick and head breaking up noises beneath her. Over 70 men were observed in the water and one prisoner was picked up. The internal injuries sustained by the prisoner resulted in his death three days later. However, from interrogation of the prisoner, it is estimated that the following damage was inflicted by this attack. Sunk: One (1) Mk No. 41 (E3), approximately 1,000 tons.

TORPEDO ATTACK NUMBER THREE - 25 April, 1945.

At 0410 I, on the morning of 25 April, 1945, the remaining two ships of the convoy were contacted by SJ on the same base course of 355 T, after a three hour chase. Three bow tubes were fired at the leading ship, which was the larger of the two, with average gyro 352, average track 122 P, torpedo run 3,470 yards, and three bow tubes were fired at the second ship with average gyro 009, average track 166 P, torpedo run 2,900 yards. Each torpedo breached once immediately after firing and two of the torpedoes made wide hooks to the left. All torpedoes eventually settled down on a straight course, although the initial hooks had dispersed them. No hits were obtained. The leading ship appeared to be a PG and the trailing ship an engines aft ship of about SB size or smaller.

4. The major torpedo casualty which occurred on the 26th of April was indeed unfortunate and the Commander Submarine Division 20L regrets exceedingly with the commanding officer, officers and crew of the U.S.S. 30D, the loss of their shipmate and friend Andrew G. JOHNSON, SL, USNR, who was washed overboard while assisting in opening the after torpedo room hatch to alleviate the serious condition caused by the torpedo casualty. The commendable manner in which the torpedo casualty was handled by all hands is deserving of the highest praise.

5. Many floating mines were sighted. Alven were sunk by gunfire.

6. The U.S.S. 30D returned from her patrol in an excellent state of cleanliness. There are no major material defects which will necessitate extending the refit period, and the 30D will be refitted in the normal refit period.

7. The Commander Submarine Division 20L congratulates the commanding officer, officers and crew of the U.S.S. 30D upon their return from the long, tenacious and well conducted patrol. It is recommended that the 30D be credited with infiltrating the following damage upon the enemy:

SUNK

One 3M Tug (Possibly CHOYO HAIU (EU), Gun Attack No. 1 2,000 tons.
One 3M Oiler (Possibly BASHI or BANSHI HAIU (IU), Gun Attack No. 1 2,000 tons.
One AM No. 41 (EC), Torpedo Attack No. 2 1,000 tons.

TOTAL SUNK5,000 tons.

1520 H Now have 80 fathoms chain aboard, taken from 0-19. Have lashed ten fathoms of it to mooring line with marlin. Will send him line from throwing gun, 21-thread, mooring line and chain, in that order.
1530 H Maneuvering to close. This is ticklish cruising. Allowing for current, try to put my bow within ten feet of his stern, fathometer reading 3 and 4 fathoms with bottom jagged and appearing to be extremely near. Can remain close to him for only fifteen or twenty minutes, twisting all the time, before I am set so close to reef that it's necessary to back clear, and come in again.
1605 H Lt. Comdr. VAN HOOFF left the ship.
1615 H 0-19 has both ends of chain. He will secure one end around conning tower tonight, and at dawn tomorrow we will take other end aboard for final tug at high tide.
1900 H Received message from 0-19 telling us he could not lift chain with his capstan and requesting us to lift it for him. Do not want to maneuver around reef after dark, at low tide and with the unpredictable current. Told 0-19 we would return at dawn.
1920 H Sent COD's SIXTH giving results and plans, and requesting instructions. Our patient, HEMPHILL, is greatly improved tonight, up and about a bit.

0815 H End of chain secured on 0-19. Now for our end.
0915 H First two attempts to have in chain uncess-
    ful. Current seems to be stronger than yester-
    day. Also, bitter end of chain, manila moor-
    ing line and at least twenty fathoms of 21-
    thread are on bottom. Have life jackets on
    end of line as marker. At each new approach,
    we pick up end of line and have in until line
    snags or until current sets us away toward
    the reef and we are forced to back clear.
0950 H SD contact, 13 miles - gave IFF.

    freeing line.
1100 H Will make one more approach, pick up manila
    line and try to clear mess on bottom. This
    is wearing on nerves.
1145 H Last line has parted. Sent message to 0-19
    that we will stand by to take off personnel.
    Felt almost as bad as the 0-19 skipper at his
    having to abandon his ship. However, did not
    see what more we could do. Had worked eight
    hours yesterday and six today with no progress.
    Had touched bottom forward ourselves at least
    once in our many approaches, and did not desire
    to have two submarines aground. Our towing gear
    was makeshift, and our personnel, though will-
    ing and resourceful, were inexperienced at rig-
    ging for a tow. Also, Jap planes and/or subs
    might have appeared at any embarrassing moment.
1200 H Posit: Lat. 80-40' N, Long. 1110-40' E. (LADD
    REFF).
1255 H First boatload aboard. Am using two rubber
    boats, lashed together with line from each
    submarine to rubber boats. Have to back clear
    and come in again after every two or three
    trips of lifeboats because of current.
1330 H Sent over two demolition charges with Gunnery
    Officer.

1700 H Ceased firing, having expended 16 rounds, for 16 hits. Remainder of 0-19 is still on reef, though it has a slightly greater list. She has a dozen holes in her hull from the 5-inch gun, her entire stern is wreckage and she was left smoking heavily. With my first torpedo fired had been at a slant-eye instead of this. Could appreciate the captain's feeling as he silently watched his boat being destroyed.
1702 H Set course for SUBIC BAY at two-engine speed.

1830 : Gunnery Officer has dug a Jap 20MM slug out of superstructure. Evidence of 10 or 12 hits in superstructure.
1848 : Sighted plane from bridge; distance about 12 miles.
1855 : Lost sight of plane.
2003 : Closed beach to investigate anchored junk. (J/15).
2010 : Determined not to be our junk.
2018 : Fired one round 40MM. to chase off native crew. Junk is abandoned, but has large cargo space amid-ships and is low in water.
2019 : Commenced firing 40MM at junk.
2022 : Junk sunk. (J/15)1 Continued search.
2110 : Commenced firing Very stars every ten minutes. Boarding party has flashlights, and one signalman striker is aboard. Have notified BLENNY and CTF 71 of situation.

2 August
0800 : Searching for junk with COD boarding party aboard. Commenced search close inshore. Have been assigned western-most sector by BLENNY who is coordinating search.
1200 : Posit: Lat. 4°-24' N, Long. 103°-32' E.
1456 : Sent COD's TENTH to CTF 71 correcting the impression that we had party aboard.
1930 : Intend to find an English-speaking native, put him ashore at the fishing village here to ask for dope on our missing party. Will hold junk as insurance of his compliance.
1955 : Alongside junk near scene of strafing attack.
1956 : One of the native crew speaks a little English.
2024 : Have man aboard. Laboriously explained what we wanted. Flooded down, heading for beach.
2130 : At 800 yards from beach put man over in junk's lifeboat, which promptly swamped.
2240 : Replaced native aboard junk and headed for rendezvous with BLENNY and BOARFISH. Until dark tonight these seemed to be little doubt that we would at any moment find our missing shipmates. They were, individually, and as a group, experienced, capable and full of common sense. They were well-armed with one Thompson, one carbine and four pistols. They carried a total of three flashlights. Each man had a sheath knife. A pre-arranged rendezvous point 5 miles south of PULO TENGGOL had been understood in case of just such an occurrence. We had returned to this point after each search along the beach. Am now beginning to be apprehensive and will try to calmly write down an "estimate of the situation".

2 August (Cont.)

1. Party are ashore.
   a. Free to move about.
      Do not believe this likely, as we would surely have noticed any attempt to attract our attention from shore, which they would be certain to do.
   b. Prisoners.
      Do not think this is probable because from all the available information it appears there are few Japs in this immediate vicinity.

2. Party are at sea.
   a. In another junk or sampan.
      If this were the case, feel we would have had some sign from them before now, as we have closed all the boats, big and small. If any turn away from us on our approach, we abandon pursuit.
   b. Prisoners on a junk or sampan.
      Very unlikely. Party is too-well-armed; prisoners would be put ashore; there have been no hostile crews encountered.
   c. Still in original junk.
      This is the most logical assumption. Wind and current have been from south southwest and could carry them far. It would be difficult, tedious and slow work to beat back south.

3. Foul Play.
   a. All or part wounded by strafing attack.
      Junk was seen to have made sail after we submerged, so the possibility of at least some of our group being okay is good. At any rate, getting any wounded men back aboard COD would be the best policy.
   b. Plane suspicious and notified convoy.
      This is the worst possibility and, unhappily, the second most logical. Plane may have seen one or more of our men aboard junk and sent a smaller escort vessel to investigate, in which case our shipmates would have been taken aboard, and the native crew and boat sent on its way. Although we did not see this happen through the periscope, junk was not in sight at all times.

GUN ATTACK NO. 7 (Cont.)
Average range was 1000 yards. This was a night attack on a large group of anchored junks and schooners in conjunction with USS BLENNY. BLENNY and COD opened fire with .50 Cal. guns over targets as warning to personnel. Shortly thereafter both submarines commenced concentrated fire with 40MM and 5-inch guns. Fire-inch gun fired on selected targets. Two hits were registered on each of six targets by COD 5-inch and 40MM guns. Additional hits by BLENNY leaves these six as definitely sunk. At least 8 other hits were scored with 5-inch gun and numerous other hits with 40MM guns, but darkness prevented further accurate evaluation of target damage.

It is believed that several other junks were severely damaged, but shallowness of water made a speedy departure imperative.

12. (I) MINES
13. No mines, moored or drifting, were observed and no mining or sweeping operations were noted.
14. (J) ANTI-SUBMARINE ESCAPES AND VASION TACTICS
15. Both convoys had extensive air cover, ranging from 8 - 10 miles in advance of convoy, 4 - 5 miles astern. These planes were both float planes and land-based fighters. On morning of 1 August, we were strafed by a Tony which was at least 15 miles ahead of convoy.
16. Convoy on 19 July had one KATIKAZE-type destroyer and one trawler as escorts. DD protriled ahead and along forward outboard flank of convoy, trawler along after outboard flank and astern. We were not close enough to convoy on 1 August to see more than one KATIKAZE-type DD as escort, although two bearings of pingers were obtained by sound. DD patrolled as before. Convoy could not have been more than a mile from the beach.
17. On 19 July, contact was made on COD and first depth charge dropped by trawler escort or by plane before torpedoes were fired. After firing, began fishtailing and working toward deeper water. Fired MAC beacon set on 3 minutes and 17.5 - 22.5 kts, and when it was believed escort had contact, fired another MAC beacon 10 minutes later at same setting. Believe that on or both of these did the trick, because when we came to periscope depth, both the DD and trawler were milling around astern on the bearing of our MAC.

(K) MAJOR DEFECTS AND DAMAGE

HULL AND MACHINERY
#3 Main Engine - 7 July 1945
: Pulled #1 unit to determine cause of wrist pin
: being frozen to the bushing. The bearing surfaces were
: found to be worn excessively on one end. The following
: pieces were removed:
: Piston Pin, (N9709 - Po. #7); Bushing, piston pin,
: (N-9707 - Pc. #3); Bushing, con-rod, (N-9709 -
: Po. #9).

No reason for this failure is offered other than
: possible defective workmanship when installed in More
: Island Navy Yard.

Subsequent inspections revealed all except six
: wrist pins were frozen to the bushing on 3M.E. Six on
: #4M.E. were in the same condition. These will be re-
: newed during the regular 1500 hour of 24-hour duty the
: next refit.

#1 Evaporator Compressor - 16 July 1945

While operating #1 evaporator the compressor froze
: and would not turn. The compressor was dismantled and
: the bushing was found frozen to the casing having worn
: a 4" groove in the casing before freezing. The casing
: was smoothed down with a file and the compressor assembled
: with a leather seal and placed in operation.

The two evaporators operate at approximately 67%
: capacity due to leaky seals and worn compressors. Two
: new compressors are required during the next refit.

— page 199 —
35 Main Engine - 15 July 1945

During the one day of voyage repairs at SUBIC BAY, Relief Crew 261 installed a tender rebuilt salt water circulating water pump on 35 Main Engine. Then the ship's force tested the engine only 12 lb. pressure could be built up at the pump. Inspection revealed that the tender had installed a left hand injector in a right hand pump. The spare pump was then installed on the engine by the ship's force, leaving the ship with no spare on hand.

A spare pump is desired during the forthcoming refit.

35 Main Generator - 19 July 1945

Routine inspection revealed a ring worn entirely around the commutator and a groove 1/16" by 1/4" worn in the third brush from the after end in each brush holder. One section of the end ball was removed and a small piece of forcign material was found lodged between two commutator bars. This was removed, twenty brushes replaced and the commutator stained with a brush seating stone and buffed. The generator was cleaned and placed in operation after being out of commission a total of 11 hours.

Master Gyro Compass - 22 July 1945

Failure of the follow-up system of the master compass was traced to an open potentiometer, and condensers 4C-11. Both parts were repaired from ship's spares.

Noise - Vibration

Throughout the patrol vibration has been experienced; particularly noticed from the bridge while running at high speeds and while accelerating. The vibration has grown progressively worse with time and at present is experienced at practically all speeds above 10 knots. Inspection of shafts and propellers at sea showed nothing apparently wrong or fouled. High cavitation noises from both screws is serious and possible bearing squeals are present with the cavitation noise.

— page 200 —
1. MAJOR DEFECTS AND DAMAGES (Cont.)

Sound Heads
JB and JK-3C have excessive clearances and rumble noisily. Believe both shafts may be sprung due to difficulty experienced at times while raising them. Excessive noise coming from superstructure reduces materially the effect of JP-1 sound gear. Parties at sea checked topside regularly, but cannot locate any loose gear; should be checked thoroughly during refit.

ORDN'NE 'ND GUNNERY
During exercise torpedo firing conducted in training area GUAM, attempt was made to fire torpedoes from tubes #6 and #7. Both torpedoes failed to leave the tubes. Investigation made subsequent to the attempts to fire indicates that possibly the tail buffers were excessively tight. It is difficult to explain why this casualty should occur in both rooms at nearly the same time and it is surmised that at the time of firing, pressure on the 200 lb. air system was down due to improper operation of reducer. No further indications of reducer malfunction were found however.

Both torpedoes were fired on the next exercise and ran hot, straight and normal for hits.

Pointer's telescope on 5-inch gun flooded out and was replaced by spare at sea.

(L) RADIO
Radio reception of the Baker Skeds was satisfactory, in that no serial messages were missed nor was there any great difficulty in copying them. Best results were obtained on 4370 kcs. from 2000 to 0400, and 9250 kcs. during the rest of the day.

Ship to shore transmission were effectively handled on 8470 kcs. except for a few exceptions. It was necessary to shift to 4235 kcs. once, and to a very high frequency, 12705 kcs. twice, when 8470 kcs. was over-crowded with transmissions. Point to point communication with NVB was not always obtainable; on three occasions it was necessary to have our messages relayed by other shore stations, namely, NPM, NPI and VHM. Unlike most relayed messages, rebroadcasts of our transmissions over the Bakersskeds indicated very few errors. Effective Jap jamming, (random CW keying), was only experienced once and was overcome by shifting frequencies.

CONFIDENTIAL
(L) RADIO (cont.)

Communicate between the submarines in our area using the SAFPLAN frequencies left little to be dis-
sired. Jamming was light and never offered any great
hindrance in clearing our traffic. On one occasion
we could not load our horizontal antenna sufficiently
to transmit over the effective SAFPLAN frequency. To
overcome this we shortened the centerline antenna by
15 feet. The whole alteration took all of five hours
but we were amply rewarded for the time spent by the
highly satisfactory results obtained using the shorter
antenna for wolf pack work. The SD mast was used while
the horizontal antenna was being shortened. The re-
sults were so gratifying that we intend to ask for a
vertical antenna during our next refit to facilitate
wolf pack transmissions.

The VHF again proved to be a highly satisfactory
piece of equipment. Although ranges of over two miles
are something to be desired, reception within 2 miles
between subs was good. The "coming" tower microphone
and speaker were helpful on several occasions to en-
able the commanding officer to communicate with the
pack commander to effect rendezvous and attacks with-
out giving up the conn of the ship.

(M) RADAR

The SJ radar performed satisfactorily throughout
the patrol with one exception. At this time we were
endeavoring to make a radar approach on a convoy and
the failure of the radar forced us to discontinue the
attack. The nature of the failure was an electrical
fire in the main control unit of the SJ-ST radar. The
fire damaged a large portion of the internal wiring
of the main control unit, causing the radar to be cut
off commission for approximately fifteen hours. It is
believed the trouble was caused by a surge in the
equipment's A.C. supply voltage. The operators of
other radar equipment operating from the same A.C.
supply observed a rise of approximately 30 volts in
the A.C. supply voltage at the time of the failure,
which burned out the pilot lights in the APR and SD
radar.

It is suggested that some type over-voltage cut-
out system be installed in the A.C. supply for the
radar equipment to prevent further failure of this
type.

1. RADAR (cont.)
2. The ST radar operated very erratically during most of the patrol. Poor ranges were obtained on both land and ship targets, several attempts were made to locate the trouble and retuning of the equipment, but with no success. The ringing time of the equipment was between 2700 and 3000 yards which has always been normal for our equipment.
3. SD, APR, BK, BN
4. The SD, APR, BK and BN radar equipment performed satisfactorily throughout the patrol, the only casualties were normal tube failures.
5. SONAR GEAR AND SOUND CONDITIONS
6. Sound conditions were quite good at all times. Pinging detected from a destroyer and small escort was heard at over 15,000 yards.
7. The TDM offered us the usual minor casualties. In the absence of any specific instructions for use of TDM (limiting speed, etc.), this equipment was never used while making spades of more than 15 knots, while submerged or at night with no moon. The most frequently occurring trouble arose from the breaking of the gut cord which pulls the stylus across the paper.
8. The JP was noted to pick up screws of a destroyer at 5,000 yards. However, interference caused by electrical machinery aboard ship decreased the effectiveness of the gear at closer ranges. A thorough investigation of the causes will be attempted during our next refit to eliminate the interference.
9. DENSITY LAYERS
10. Few density layers were found in this area, the water maintaining usually a constant temperature with very slight negative gradients. One notable exception was a six degree negative gradient between 30 and 100 feet encountered July 19th and which proved very useful in evasion tactics that day.

:  (P) HEALTH, FOOD AND HEALTHBILITY
:  Health:
:  During the patrol, there was the usual number of
:  colds, constipation, fungus of the feet, and many cases
:  of heat rash. They responded readily to routine treat-
:  ment. One man developed an urethral discharge, which
:  was thought to be URTICITIS CUTIS, NON-VIRAL. The
:  Sulfadiazine helped to eliminate his ailment.
:  Two men were admitted to the sick list during the
:  month of July, one for POISONING CUTS, LID, believed
:  to be a result of picnicking during the rofit, and which
:  accounted for nine sick days. This man failed to re-
:  spond to sulfa treatment, and it was necessary to com-
:  mence intravenous feeding. Finally as a last resort,
:  penicillin was administered, the patient responding
:  after the second injection and was shortly back to nor-
:  mal. Another, for FOOD INTOXICATION, BOTULISM, believed
:  due to a bad can of Deviled Ham. This man was on the
:  sick list for three days.
:  Five members of the boarding party spent about forty-
:  eight hours on a native track, and were forced to use the
:  food and water present aboard. Only two men experienced
:  ill feelings from the change of diet. They suffered in
:  a mild form, abdominal cramps and diarrhoea, which did
:  not incapacitate them from duty. The symptoms quickly
:  left without any form of treatment.
:  Foods:
:  The food throughout the patrol was very good, the
:  men varied and well prepared.
:  Habitability:
:  The ship was kept clean and comfortable with daily
:  "clean ups". The two days that the Dutch crew were a-
:  board, the boat was crowded and hot; periodical
:  through the boat were made by opening the forward tor-
:  pedo room hatch which helped considerably.

Subject: U.S.S. COD (SS224) - Report of Seventh Patrol.

1. The seventh war patrol of the U.S.S. COD under the command of Lieutenant Commander E.M. STERROCK, Jr., U.S. Navy, was conducted in two phases; the first off the coast of INDOC-HINA, and the second in the GULF of SIAK. The patrol was of 49 days duration with 19 days spent in patrol areas. It was highlighted by 12 successive days of profitable gun actions in the GULF of SIAK.

2. On 9 and 10 July the COD was skilfully maneuvered for 14 hours in close proximity to the grounded Dutch Submarine O-19 in a vain endeavor to tow her clear of INDOC RAAF. The crew of the O-19 was finally transferred to the COD and the O-19 was completely destroyed by two demolition charges, two torpedo hits, and sixteen hits from COD's 5-inch gun. The high speeds, 34 and 35 knots, of the LK.13 torpedoes for the short runs is noted.

3. On 19 July, the COD made an unsuccessful submerged attack on a small convoy. Convoy had air cover and COD had to run at standard speed submerged in smooth sea to close. She was bombed or depth charged just prior to firing. Three torpedoes were fired on sound bearing immediately thereafter. No hits were obtained. The counter attack was not too close. That night, after the unsuccessful attacks on the same convoy by BRILI and BUMPER, an en-roun was made to attain position ahead of the convoy. On commencing approach the radar power supply burned out. Without radar, a submerged daylight attack appeared to be the logical choice and COD proceeded to a position to intercept the convoy after dawn. No further contact was made.

4. During the period 21 July - 1 August, the COD made twenty gun attacks on twenty-three junks and motor sampans, plus one towed oil barge, sinking them all for a total of 2200 tons. A total of sixty-five rounds of 3-inch and 1092 rounds of 40 IAM ammunition were expended during these attacks. Her actions in regard to boarding, inspection, and thoughtfulness of the lives of native crews symbolize the type action which has made the United States respected the world over.

— page 212 —
5. The obvious objections to using a submarine as a gunboat were practically and thoroughly demonstrated during this aggressive series of ten day actions. On 21 July the CD was twice bombed while in the act of diving. On 1 August she was straffed by a fighter plane and forced to dive, leaving her boarding party unassisted on an enemy ship. Fortunately the boarding party was rescued by the BLENNY after 48 hours. They were in good health and suffered no ill effects from their junk cruise. At this stage of the war such tactics are essential, despite the obvious objections, if submarines are to continue to do a heavy share of damage to the enemy.

6. The practice of firing lk.14 and lk.18 torpedoes in the same salvo, as done by the CD, is not recommended. The inherent advantage of each type torpedo is lost. The wakeless feature of the lk.18 is compromised by the lk.14 in the salvo. The high speed advantage of the lk.14 is not fully utilized with 30 knot torpedoes fired in the same salvo. An additional load is placed on the TDC operator at his busiest moment.

7. Spirit and morale aboard the CD were high when she arrived from this shooting patrol. Material condition is fair with extensive work indicated on the main engines, hydraulic system, master gyro and thrust bearings.

8. The Squadron Commander welcomes the CD back to this area and congratulates the Commanding Officer, officers and crew on their arduous, extended, and successful gunshot in shallow enemy controlled waters.

Subject: U.S.S. COD (SS224) - Report of Seventh War Patrol (26 June to 13 August, 1945).

1. The Seventh War Patrol of the COD under the command of Lieutenant Commander E. M. WESTBROOK, Jr., U.S.N., was spent partially in life-guard duties off the INDIO-CHINA Coast and partially on offensive patrol in the GULF of SIAM.

2. COD was one of the first ships employed in attempting to break up the considerable small boat traffic in the GULF of SIAM which was transporting valuable enemy cargo in small lots to and from SINGAPORE. In twelve days she sank 23 junks and 1,000 tons of cargoes consisting of rice, sugar, oil, soap, crude rubber, coffee, paper, horseshoes and army blankets. The Commanding Officer was careful throughout to inspect and determine the nature of the cargoes and provide for the safety of friendly natives. In addition the COD made a valiant effort to pull a grounded Dutch submarine from a reef, but finally had to salvage the crew and destroy the ship. This episode and a later one of losing a boarding party eventually recovered by another submarine, are covered by the Squadron Commander's endorsement whose remarks are fully concurred in.

3. The award of the Submarine Combat Insignia for this patrol is authorized.
