Legend:

Laid down means that the ship's construction was officially started by laying down the keel (often just a single steel beam but could also mean the first of many pre-fabricated sections).

Launched means that the ship was launched from its shipyard, it then began its fitting out period (installation of smaller systems, weapons etc.) - in many yards the ships were launched very complete and needed little work afterwards.

Commissioned is when the navy takes the ship officially over and gives command of it to its new captain.

The target was thought to be of 1700 tons. 1710 hours - Fired five torpedoes from 1700 yards. Went to 80 feet after firing the last torpedo. 1711 hours - Heard a loud torpedo explosion at the correct interval for the 3rd or 4th torpedo. Heard the HE of the escort approaching from the South. Continued to the North at 5 knots while still at 80 feet. 1728 hours - HE of the escort ceased so returned to periscope depth. Found only the escort and one Jake aircraft in sight.

Royal Navy Submarine HMS Trenchant: 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)
