On 26 December 1939, Triumph hit a German mine in the North Sea. Eighteen feet of bow was blown off and her pressure hull was also damaged, but fortunately the torpedoes in the torpedo tubes did not detonate. She managed to limp back home under the protection of fighter aircraft and destroyers, and was under repair at Chatham Dockyard until 27 September 1940.
Operating in the Mediterranean from early 1941, Triumph sank the Italian merchants Marzamemi, Colomba Lofaro, Ninfea, Monrosa, the Italian auxiliary patrol vessels V 136 / Tugnin F, Valoroso, V 190 / Frieda and V 137 / Trio Frassinetti, the Italian tug Dante de Lutti and salvage vessel Hercules, the German merchant Luvsee, and the Greek sailing vessels Panagiotis and Aghia Paraskeva. She also damaged the Italian armed merchant cruiser Ramb III, the Italian tankers Ardor and Poseidone, the Italian merchant Sidamo and the German merchant Norburg
Triumph was also used for covert operations, such as landing agents in German occupied areas. She was planned to be used as a rendezvous for commandos in Operation Colossus, but this had to be cancelled when the landing site became untenable. She undertook one such mission in December 1941, in which she successfully landed agents in Greece. She was lost just over a week later, off Greece, probably to a collision with a mine in early January 1942. All fifty-nine crew were lost.
There is a memorial to her and her lost crew members in All Saint's church, Lindfield, West Sussex.
