Triton was involved in one of the gravest submarine tragedies in the Royal Navy, and also obtained the most important success of any boat of the class.

Less than one week into the war, in the second torpedo attack of the war by a British submarine (9th September), she fired two torpedoes at Oxley, one hit and sank the British submarine.

Late on the 10th September, off Obrestad, the two British submarines encountered each other. Oxley replied to Triton's challenge with a non-working signal lamp, the former was mistaken for a U-boat and sunk. There were only two survivors, Oxley's commanding officer and one rating.

Seven months later, 10th April 1940, during the invasion of Norway she launched six torpedoes at a German convoy from 2,500 yards. Three torpedoes found their mark, sinking the Friedenau (5,219GRT), Wigbert (3,648GRT) and V1507 (ex-Rau VI, 154GRT). Some 900 German army personnel were drowned, this was the worst disaster suffered by the Germans during the operation.

Believed lost by mining almost certainly struck one of the many mines in this area probably off Brindisi on 7th December 1940.
