Thanks for the links! Interesting stuff.
This was against two Italian liners, the Sumatra and the Volpi, at Phuket, north of Penang, Malaya. On 27 October 1944, the Trenchant (Lt. Cdr. A.R. Hezlet RN) successfully launched two Mk.II 'Terry' Chariots. These were a great improvement on the Mark 1, with the two-man crew sitting back-to-back. The two chariot teams comprised Sub-Lt 'Lofty' Eleridge with Petty Officer Woollcott, and Petty Officer W.S. Smith and Steward A. Brown. The first pair successfully attacked and sunk the Sumatra in a text-book raid. The second team found that they unable to attach their charge to the hull of the Volpi, due to the deep draught and lack of space underneath the hull and then the barnacle-encrusted hull itself. Brown, therefore, had to place the charge inside the ship's engine-room, a job which took twenty extra minutes. Both crews returned to the Trenchant and were able to watch as their targets exploded. This was the last chariot attack of the war. After the war, Chariots were used in clearing harbours of wrecks and mines.
