HMS Truant (N68) was a T-class submarine of the Royal Navy, launched on 5 May 1939 by Vickers-Armstrongs in Barrow. As a vessel of the T-class, she was designed for versatility and operational effectiveness during World War II. Although specific dimensions are not provided in the source, her service history indicates she was capable of extended patrols across diverse theaters, including Home waters, the Mediterranean, and the Pacific Far East. Truant’s combat record was notable for several engagements. Her first major victory involved damaging the German light cruiser Karlsruhe off Kristiansand, Norway, disabling its engines and power stations before the Karlsruhe was scuttled by the German torpedo boat Greif. She also engaged in operations against merchant ships, including the attack on the British merchant Alster, which she missed, and the interception of the German merchant Tropic Sea, a vessel with a complex history involving Norwegian service, capture by Germans, and eventual scuttling. During this period, Truant rescued survivors from the Haxby and Tropic Sea, including the captain and crew, showcasing her role in rescue operations. In the Mediterranean, starting from mid-1940, Truant sank multiple Axis vessels such as the Italian merchant ships Providenza, Sebastiano Bianchi, Multedo, the tankers Bonzo and Meteor, and others. She damaged vessels including the Italian tanker Prometeo and the Italian torpedo boat Alcione, which was later lost. Her operations extended to the Far East in 1942, where she participated in the Battle of Badung Strait, launching torpedoes at the Japanese cruiser Nagara, though without hits. She successfully sank Japanese merchant ships Yae Maru and Shunsei Maru and engaged in combat with Tamon Maru No.1, which sank shortly after. By late 1942, engine trouble hampered her missions, and after a lengthy refit completed in May 1943, she resumed training and patrols, including a planned sortie against the German battleship Tirpitz. However, engine issues persisted, preventing further combat patrols. In 1945, she was used as a trials vessel, notably testing snorkel equipment. After surviving the war, HMS Truant was sold for scrap on 19 December 1945 but was wrecked en route to the breakers in December 1946. Her service exemplifies the versatility and resilience of the T-class submarines during wartime operations.
