0635 hours - Dived
1215 hours - Sighted an unidentified aircraft
1810 hours - Surfaced
1814 hours - Sighted two submarine chasers about five nautical miles inshore steering north-west along the coast. They sighted Tantivy at the same time and turned towards. Tantivy retired to seawards at 13 knots. One of the submarine chasers turned towards the coast again to other continued to follow Tantivy. A merchant was now sighted about two to three nautical miles to the westward of the escorts in position 05°15'N, 97°10'E. After about ten minutes the submarine chaser that was following Tantivy abandoned the pursuit. Tantivy now proceeded towards the south-east point of Pulo Weh to intercept as the merchant was obviously bound for Sabang.
(5)

1 Aug 1944
While trying to attack the merchant spotted the previous day, HMS Tantivy (Cdr. M.G. Rimington, DSO, RN) is spotted by an aircraft. The attack therefore had to be broken off.

(All times are zone -6,5)
0508 hours - Dived off the south-east corner of Pulo Weh.
0608 hours - The masts and bridge of a ship were sighted. Also one single engined aircraft was patrolling over the Malacca Passage. After a while the ship suddenly turned towards leaving Tantivy perfectly placed for an attack. At 0704 hours when Cdr. Rimington wanted to have a last quick peep through the attack periscope an aircraft bomb went off. Fortunately it was not close. The aircraft had probably seen us and dropped the bomb as a warning that a submarine was very close. The target immediately changed course. One of the escorts was only 400 yards away and turned strait towards Tantivy. Cdr. Rimington immediately ordered Tantivy deep. It was only after seven minutes that the first two depth charges were dropped and these were not close. When Tantivy was able to return to periscope depth the target could be seen stern on and out of range. At the same time a twin-engined bomber, a Sally, was seen to dive towards us from 1000 feet but failed to drop anything as Tantivy went deep again
0910 hours - Returned to periscope depth to find the sea and sky clear. Proceeded to a position to the north-west of the One Fathom Bank
1852 hours - Surfaced.
(5)

6 Aug 1944
HMS Tantivy (Cdr. M.G. Rimington, DSO, RN) is spotted by a Japanese torpedo boat. She is depth charged but no damage was done.

(All times are zone -6,5)
0440 hours - In position 210°, 3 nautical miles from Observation Island (Butangs) a light was sighted flashing. It was challenging us. Tantivy turned to the south stern on to the light. A small destroyer was then sighted that started to challenge again. We had clearly been sighted and as it was getting light Cdr. Rimington dived at 0449 hours. Tantivy went deep immediately expecting to be attacked. The destroyer was picked up on the Asdic and was approaching at 12 knots. No attack however developed and by 0540 hours Tantivy came to periscope depth. It was now light enough to see the destroyer, (Otori class) about 4 nautical miles to the eastward steering towards Langkawi
0750 hours - The destroyer was seen to make off towards Penang. Also the first aircraft of the day was sighted at this time. During the day at least one aircraft was in sight. Sometimes up to three were in sight at the same time
1815 hours - The mast of an escort vessel (most likely the Otori-class destroyer again) was sighted bearing 110°, 5 to 6 nautical miles. She appeared to be heading slowly north. Tantivy was at this time about 3.5 nautical miles to the south-east of Observatory Island. Cdr. Rimington turned to the west to open up the range to the vessel before surfacing. She was very soon out of sight in the dusk
1908 hours - Surfaced
2030 hours - The after lookout sighted the destroyer closing us. She was then about 4 nautical miles away on the starboard quarter. Turned to the south-west, stern on to the destroyer and increased speed to 13 knots. The destroyer soon followed us and appeared to have increased speed
2116 hours - Distance was now about 3 nautical miles and decreasing so there was no other choice then to dive. Just before diving a second vessel was sighted bearing 050 about 4 nautical miles away. On diving Tantivy turned to port to 090°, hoping the destroyer's Commanding Officer was thinking the submarine would turn to seaward. The destroyer steamed on to the diving position and as she crossed fairly close astern she dropped a single depth charge. She ten reduced speed and to Cdr. Rimingtons disgust also turned to Port and steamed up Tantivy's Starboard side dropping two more depth charges about half a mile apart. The destroyer then turned to Port, crossed close ahead and then drew out to the North of Tantivy. Cdr. Rimington started to turn slowly 180° to Starboard to 270°. During this time nothing had been heard from the second vessel. The destroyer appeared to be at fault. As the destroyer drew clear, Cdr. Rimington took the risk to increase speed to get clear of the search area. At this moment the second vessel was heard to approach fast from the South-West (Port bow). She passed very close to port and then joined the destroyer. The game of cat and mouse continued during the whole night and Tantivy was unable to surface during the night so measures were taken to conserve battery power and improve the air quality.

HMS Tantivy (Lt. P.H. May, RN) is attacked with bombs by a Japanese aircraft in position 07°30'S, 101°56'E. Three bombs were dropped but these all failed to explode.

(All times are zone -6,5)
1016 hours - In position 07°30'S, 101°56'E dived for an aircraft overhead reported by a lookout. The aircraft was not picked up by radar. The aircraft was identified as a Betty flying at 1000 feet.

4 Sep 1944
HMS Tantivy (Lt. P.H. May, RN) makes a torpedo attack on a Japanese merchant. Three torpedoes were fired but these all missed their target.

(All times are zone -8)
0632 hours - Dived south of Flat Cape
1100 hours - Established a patrol off Flat Cape
2212 hours - Radar reported a possible ship 7400 yards away. This was soon seen to be a submarine chaser that turned towards
2217 hours - Dived and turned away. H.E. was soon heard to fade away
2235 hours - Surfaced and found nothing in sight so set off at 13 knots towards the last bearing of the H.E. After 5 minutes an object was sighted and a few minutes later two small ones ahead. It was decided that this was a worth-wile target. It looked like they were coast crawling very close inshore along Flat Cape. Tantivy increased to full speed. Radar range was 7800 yards. When it came down to 6000 yards the course was estimated at 110°, which was through the strait, passing close to Krakatoa, speed was 9 knots. The escorts were broad on each bow of the target so it was decided to fire from 4000 yards, the nearest escort would then be 3000 yards away
2314 hours - After slowing down, three torpedoes were fired, five torpedoes were intended but the target turned away after the third torpedo so the other two were not fired. The target turned away and Lt. May thought they had been spotted so he turned away and increased speed. In the meantime they started to reload the torpedo tubes that had been fired. However the target remained on her new course, approximately 350°, and also the escorts did nothing. So it was decided to follow them at slow speed. It now appeared they continued to coast crawl until they were north of Tabuan, then cross to the other side of Samanka Bay, coast crawl down again and so through the strait. Lt. May decided to cross to the west coast of Tabuan and then steer north up the coast and get a shot at them as they crossed north of the island. This was done but despite that Tantivy ran at full power plus, they passed north of the island while the range was over 5000 yards. After been foiled again it was decided that rather than follow them round and been silhouetted against a very bright moon while they were against the far shore, Tantivy would turn, go south of Tabuan and meet them on opposite course, thus getting between them and the shore. This was done but when they were sighted again at ......... (continues on 5 September 1944)

5 Sep 1944
HMS Tantivy (Lt. P.H. May, RN) torpedoed and sank the Japanese merchant cargo ship Shiretoko Maru (1799 GRT, former Dutch Siberoet, built 1927) in Semangka Bay in position 05°44'S, 104°58'E.

(All times are zone -8)
(continuation of 4 September 1944) ??? 0238 hours it was seen that they were so close inshore that the attack would have to be from the seaward and as the moon would be behind Tantivy again the attack had to be submerged
0310 hours - After manoeuvring into position for attack and having dived, 7 torpedoes were fired from 1500 yards. One minute after firing a dull flash was observed followed by a fairly heavy explosion. The nearest escort, 700 yards away, turned towards so Lt. May took Tantivy deep. H.E. from the target ceased. The escort that turned towards counter-attacked for half an hour dropping 11 depth-charges in all but none were very close. The other escort did not participate in the counter-attack. Tantivy remained deep until daylight, then came to periscope depth and set course for Princess Island. Nothing further was sighted all day
1928 hours - Surfaced and patrolled south-west of the Princess Passage.

0751 hours - Two bombs were dropped close aboard. These were only small bombs and were followed by machine gun fire. Tantivy was then at 22 feet with nothing under the keel
0803 hours - Another bomb, and more machine gun fire followed. All were rather distant. Tantivy was now at 34 feet
0810 hours - Now at 45 feet made a 45° course change
0850 hours - Came to periscope depth to see if the aircraft was still about, he was so went to 60 feet and altered course again
1400 hours - Came to periscope depth. Sighted an armed coaster steering 265° at 5 knots along the coast. Decided to sink this ship with a torpedo, from tube no.8. This torpedo had been leaking air for several days and was considered to be to unreliable to be fired in a salvo
1501 hours - In position 05°45'S, 119°44'E fired this torpedo from 3000 yards. The torpedo missed the target
1511 hours - Surfaced for gun action
1520 hours - Sighted an escort vessel on the port bow, 8 nautical miles away. Considered that there would be enough time to deal with the coaster before the escort got to near
1525 hours - Opened fire on the coaster at 3600 yards. The target fired back with possibly a 12 pounder gun and a machine gun
1532 hours - In position 05°44'S, 119°44'E, the target was seen to be burning furiously, listing to starboard and was probably beached. It was considered that the target was a total loss. Turned to seaward to reach deeper water
1534 hours - Dived. When the escort vessel came nearer nothing was dropped at all
1615 hours - An aircraft was seen to join the escort
1728 hours - Another escort vessel arrived but it remained close inshore
1730 hours - Lt. May was looking through the periscope at the second escort vessel when it was suddenly totally obscured by a large explosion. When it reappeared it had settled considerably and it was considered that it was on the bottom as it was very close inshore. It is thought possible that by chance it set off the torpedo fired earlier as the positions checked (the torpedo was fitted with a magnetic exploder)
1820 hours - Surfaced and set course for Sangean Island.

23 Oct 1944
HMS Tantivy (Lt. P.H. May, RN) sank a Japanese sailing vessel with gunfire west of Sangean Island in position 08°15'S, 118°55'E.

(All times are zone -8)
Patrolled on the surface in the vicinity of Sangean Island during the forenoon. The visibility was very poor
1215 hours - In position 08°15'S, 118°55'E sank a small schooner with gunfire
1300 hours - Visibility much improved. Dived. Nothing in sight
2030 hours - Closed firm radar contact at 8000 yards and chased. This later turns out to be most likely a US submarine (possibly USS Muskallunge) so the chase was abandoned.
(5)

25 Oct 1944
HMS Tantivy (Lt. P.H. May, RN) sank the Japanese barge No. 136 and the Japanese motor sailing vessel Tachibana Maru No.47 with gunfire off Miro, Sumbawa, Netherlands East Indies in approximate position 08°08'S, 117°45'E.

(All times are zone -8)
0635 hours - Dived and inspected Batahai Strait and anchorage. Sighted one topsail schooner steering North-East from Salah Bay. As there was almost no wind, Lt. May decided to leave the schooner for the moment as he could not get far hoping that bigger pray might show up
1500 hours - Sighted a large coaster coast crawling northwards
1520 hours - Sighted another large coaster following the first one
1612 hours - Both coasters anchored two nautical miles apart off Kunanga village
1628 hours - In position 08°08'S, 117°46'E. Fired one torpedo at the nearest (and largest) coaster from 1000 yards. After 22 seconds and after running 400/500 yards the torpedo exploded prematurely
1629 hours - Surfaced for gun action. The target returned fire with machine guns but this soon ceased as the target burst into flames. Fire was checked and course was set to go after the second coaster that was getting under way. The crew opened fire on Tantivy but started to abandon ship before fire was returned. This coaster was also sunk with gunfire. Tantivy now set off at 14 knots to go after the schooner seen earlier this day
1830 hours - In position 08°05'S, 117°53'E sank the schooner with 3 starshell and 1 H.E. round and two pans of Oerlikon
1835 hours - Set course for deeper water to the westward
1900 hours - Set course for Sangean Island
2000 hours - The coasters were still seen burning from a distance of 15 nautical miles.

26 Oct 1944
HMS Tantivy (Lt. H.S. May, RN) damaged a coaster off Sangean Island in position 08°15'S, 119°10'E.

(All times are zone -8)
0608 hours - Sighted a coaster steering north-west from Banta Island, range 12000 yards. Closed at 14 knots. The coaster was seen to alter course to the west to pass through the channel between Sangean Island and Naru Point. Tantivy kept dead astern of the coaster with the rising sun behind them
0713 hours - It was decided to fire two torpedoes against the target. In position 08°16'S, 119°09'5"E fired tube 5. This torpedo immediately turned hard to starboard and passed close under the stern. Went to full speed to get out of the way as soon as possible. After 15 minutes turned our attention to the coaster again
0737 hours - In position 08°15'S, 119°10'E fired a torpedo from no.7 tube. This torpedo also malfunctioned and exploded 300 yards away. This also made the coaster decide that Tantivy was up to no good. He opened fire with a 12 pounder gun and two heavy machine guns. Fire was quite accurately. Tantivy made off at full speed but after about a minute turned towards now opening fire with her deck gun. 20 rounds were fired with four with (with two on the waterline) before ammunition ran out. The Oerlikon also jammed at the same moment. The coaster ran towards the shore and beached herself on Sangean Island. Her stern had settled down. The action had to be broken off until the Oerlikon was repaired as the coaster was still firing with their guns. The barrel of the Oerlikon had to be replaced
0847 hours - Dived for an aircraft. It was now decided to return to Fremantle as we were out of ammunition for the deck gun and the torpedoes proved to be unreliable. Set course for Lombok Strait
1712 hours - Surfaced and completed changing the barrel of the Oerlikon.

28 Nov 1944
HMS Tantivy (Lt. P.H. May, RN) arrived at Exmouth Bay to top up with fuel and load fresh provisions. Also minor defects were repaired. She departed from early the next morning. (5)

29 Nov 1944
HMS Tantivy (Lt. P.H. May, RN) suffers a burned out motor for the fore hydroplanes. (5)

30 Nov 1944
HMS Tantivy (Lt. P.H. May, RN) suffers three cracked breech ends. There was only one spare carried, it was decided to keep it in reserve for the moment. (5)

1 Dec 1944
One of the breech ended cracked began to leak so badly that it had to be replaced with the spare. Also a hole in the Port muffler tank was repaired. (5)

2 Dec 1944
HMS Tantivy (Lt. P.H. May, RN) has to abandon her Northbound passage of Lombok Strait.

(All times are zone -8)
2 December 1944
2000 hours - Started passage of Lombok Strait
2242 hours - In position 08°33'S, 115°47'4"E sighted one motor launch ahead, range was 3000 yards. Turned to the westwards to go round him. Just before reaching the shelter of a rain squall at 2250 hours a violent lightning flash disclosed two more motor launches right ahead, in the rain squall in position 08°31'7"S, 115°46'5"E well under 1000 yards away. Turned 180° and increased to full speed to run around the original motor launch inshore to eastwards. Reduced to 14 knots after 10 minutes. After 3/4 of an hour, when near the North entrance to the Straits, close to the eastern shore, with the original motor launch abaft the beam drawing aft, range 2000-3000 yards, the moon shone out at full brilliance. After a few minutes the motor launch increased speed and turned towards
2348 hours - Dived to 230 feet in position 08°26'1"S, 115°54'7"E and rigged for depth charging.

3 December 1944
0057 hours - A pattern of four depth charges was dropped right on top of us, they were to close for comfort. 10 more depth charges were dropped in the next minutes. These caused minor damage (and violent squealing from the rats behind the woodwork !!!). During the first pattern of depth charges something scraping down the side was reported from aft and the port screw became extremely noisy. Oil fuel was now leaking into the boat through the spindle of number 5 Port Kingston Valve, and the vent to number 3 Port External. It seemed very likely that we were leaking oil fuel from the external tanks, which would also account for the accuracy of the depth charging so at 0130 hours turned South to run back trough the Straits
0330 hours - Surfaced in position 08°35'2"S, 115°50'9"E to get clear of the Straits by daylight
0402 hours - In position 08°38'8"S, 115°48'3"E sighted a motor launch 3000 yards away. Turned to Port to run around him
0414 hours - Turned back to original course but the wheel jammed. Both engines were stopped but we went in the direction of the motor launch
0422 hours - The range was about 2500 yards so dived in position 08°40'7"S, 115°50'2"E and rigged for depth charging. No attack followed however. As daybreak was at 0500 hours decided to remain dived until well clear of the Straits
0830 hours - Surfaced in position 09°04'8"S, 115°39'5"E to charge and make good defects. No fuel leaks were found
1400 hours - Dived in position 09°15'S, 114°56'5"E and went to 120 feet to repair steering gear
1852 hours - Surfaced in position 09°13'3"S, 114°54'E and set course for Lombok Strait
2350 hours - Commenced passage of the Strait.

4 Dec 1944
HMS Tantivy (Lt. P.H. May, RN) successfully transits Lombok Strait Northbound.

(All times are zone -8)
0102 hours - In position 08°36'8"S, 115°41'5"E sighted two motor launches 3500 yards away. Turned away to run round them
0137 hours - Altered course back North again
0300 hours - Passage completed
1313 hours - In position 06°36'2"S, 116°30'E dived for 2 aircraft detected by radar, range 7000 yards. They were not seen. The radar set had just been switched on again after 10 minutes of cooling, which accounts for the short range
1400 hours - Came to 20 feet to sweep round with the radar before surfacing. Got a radar contact at 2000 yards, went to 80 feet
1445 hours - Surfaced in position 06°31'4"S, 116°30'E
1930 hours - Discovered 1/4 inch of salt water in the drain oil tank, as the separators could deal with this amount it was decided to carry on until the next morning, then dive and investigate.
(5)

5 Dec 1944
Traces of salt water were found in both camshaft cases. Also Tantivy spent the day submerged to make repairs to both main engines.

(All times are zone -8)
0340 hours - Found traces of salt water in both camshaft cases, stopped both engines
0420 hours - In position 05°16'S, 114°34'E went ahead on both engines (320 revs) to carry out an attack on a darkened ship. This turned out to be a fishing prau
0555 hours - Dived in position 05°16'1"S, 114°31'E to make good defects on main engines
1720 hours - Surfaced in position 05°06'S, 114°11'E and proceeded.
(5)

6 Dec 1944
More engineering problems were found aboard HMS Tantivy. They were of such nature that it was decided to abandon the patrol and return to Fremantle.

(All times are zone -8)
0645 hours - Dived in position 04°32'S, 112°12'E to clean inlet boxes and examine breech ends. It was discovered that number 6 Starboard breech end was cracked so badly that it would have to be cut out. The situation was now as follows. The Starboard engine with only five cylinders could not propel by itself and could only give a Down Group standing charge of 200 amps per battery. One of these five cylinders had a cracked breech end, likely to go completely at any time, which would put the engine completely out of action. The Port engine was still going on all six cylinders but one of the cylinders had a cracked breech end also likely to go at any given time. The spare breech end had already been used. Thus Tantivy was left with virtually only one engine. As the patrol are was still over 800 nautical miles away. A signal was sent to base of the intentions
1025 hours - Surfaced in position 04°32'N, 112°12'E and set course for Lombok Strait.
