She had been in convoy with Oceania, Neptunia and Marco Polo escorted by the destroyers Ugolino Vivaldi, Nicoloso da Recco, Vincenzo Gioberti, Alfredo Oriani, Scirocco and the torpedo boats Giuseppe Dezza and Partenope.

(All times are zone -2)
0636 to 0725 hours - Sighted the torpedo boat Partenope, 2 MAS boats and 3 minesweepers. They were passing about a mile inshore of Unique. From their movements the position of the swept channel was fixed and Unique was placed near the entrance to await the convoy of troopships that was reported.

2015 hours - Unique was at periscope depth when an explosion was heard. A thin column of water was sighted about one mile away through the periscope. This was repeated four times. It appeared that Unique was bombed from the air although no aircraft were sighted. Two minutes later, HE was heard and fire was opened on the periscope with a gun. Unique was taken to 90 feet and course was altered. For the next 45 minutes Unique was hunted but no depth charges were dropped. (3)

6 Jul 1942 (position 72.07, 31.09)
HMS Trident (Lt. A.R. Hezlet, DSC, RN) encounters two German U-boats in position 72°07'N, 31°09'E. They were not attacked (see below for the reasons).
These two U-boats were most likely the U-334 and U-456.

(All time are zone -2)
0925 hours - While submerged in position 72°07'N, 31°09'E the officer of the watch sighted two objects to the northward. The objects were distorted by mirage and could not be identified. As they might well have been tops of the German heavy units thought to be in the area they were closed at full submerged speed for five minutes until it was seen that they were two German U-boats. Their course and speed was 195° and 8 knots. They passed 2300 yards ahead of Trident.

They were not attacked for the following reasons (in order of importance)
1) It was thought they German heavy units were to the eastward about to attack the scattered convoy PQ 17. Trident was well placed to intercept them on their return.
2) The patrol orders stated that a full salvo had to be retained for these German heavy units. Therefore only 4 at max. could be fired as two torpedoes were already expended during the scuttling of the American merchant Alamar on 27 May. If a salvo of 10 torpedoes was to be retained four out of the six C.C.R. (magnetic) pistols would have to be expended.
3) The U-boats were homeward bound and therefore no longer a menace to the convoy.
4) We were instructed by signal not to attack submarines to the west of 30'E. Despite the fact that Trident was to the east of 30'E the order was clearly meant to apply. (10)

25 May 1945 (position -6.23, 110.55)
HMS Trenchant (Cdr. A.R. Hezlet, DSO, DSC, RN) sank the Japanese auxiliary minesweeper Wa 105 (175 tons, former Dutch Grissee) east of Mandalika Island in position 06°23'S, 110°55'E.

(All times are zone -9)
1205 hours - In position 010°, Mandalika lighthouse, 3.3 nautical miles, sighted an eastbound coaster of about 550 tons and one escort vessel bearing 221°, distance 3 nautical miles.

1245 hours - Surfaced in position 031°, Mandalika lighthouse, 3.6 nautical miles to engaged the escort vessel with gunfire from 4000 yards. The escort immediately increased speed and turned towards opening fire with automatic weapons. When range had decreased to 2500 yards a number of hits were scored on the escort resulting in it to decrease speed and turn away. The 4" gun then refused to eject and empty cartridge so Trenchant turned away to clear the gun. Firing with the Oerlikon nonetheless continued. After a few minutes the gun was cleared. The escort was now out of control and on fire abaft the bridge. Fire with the 4" gun was re-opened. Shortly afterwards the enemy was seen to abandon ship.

1302 hours - The escort was now stopped , range was 400 yards. Fired a torpedo from nr.4 tube. The torpedo was set to 4 feet but did not reach this depth due to the short range.

1306 hours - The escort was seen to sink. About 15 survivors were left in the water. In all 115 rounds of 4" were fired. The coaster meanwhile had beached herself. She was taken under fire from 6000 yards but after 12 rounds fire was checked as she proved very difficult to hit at that range and it was considered wise to withdraw to deeper water before aircraft arrived at the scene.

1352 hours - Dived in position 024°, Mandalika lighthouse, 4.4 nautical miles.

1445 hours - Sighted the first aircraft arrive on the scene of the sinking.

The coaster must have been have been the Japanese naval auxiliary Kamisihima Maru (556 GRT, built 1941) (29)
