Experts are certain that a wreck discovered in the Aegean is HMS Triumph. Built in Barrow-in-Furness, the T-class boat was commissioned in May 1939, but disappeared in January 1942 with 64 crew.
Triumph initially served in home waters, surviving a mine strike in which 18ft of her bow was lost – incredibly without human casualties – and was in repair until late September 1940. She reached the Mediterranean in December 1941 and had a string of successes, sinking the Italian merchantmen Marzamemi, Colomba Lofaro, Ninfea and Monrosa, as well as a tug, a salvage ship and two sailing vessels. She also sank several patrol craft and damaged the auxiliary cruiser Ramb III and the cruiser Bolzano.
Triumph sailed from Alexandria on her twelfth patrol on December 26, 1941, part of which involved the landing of two MI9 operatives and their wireless operator at Antiparos in Greece. She was supposed to retrieve them on January 9, 1942, but failed to meet the rendezvous.
