HMCS Truro (pennant J268) was a Bangor-class minesweeper constructed for the Royal Canadian Navy during World War II. Laid down on 20 March 1941 by Davie Shipbuilding in Lauzon, Quebec, and launched on 5 June 1942, Truro was commissioned into service on 27 August 1942. As part of the diesel-powered variant of the Bangor class, she measured approximately 162 feet in length with a beam of 28 feet and a draught of 8 feet 3 inches. Displacing around 592 long tons standard and 690 long tons fully loaded, the vessel was powered by a 9-cylinder diesel engine generating 2,000 brake horsepower, enabling her to reach a maximum speed of approximately 16.5 knots. Her armament included a single QF 12-pounder gun mounted forward, a QF 2-pounder gun aft, and eventually, QF 20 mm Oerlikon guns on the bridge wings. For convoy escort duties, she was equipped with two depth charge launchers and chutes for carrying up to 40 depth charges. Throughout her service, HMCS Truro participated actively in convoy escort operations, notably in the Battle of the Atlantic and the Battle of the St. Lawrence. She was assigned to the Western Local Escort Force and later to Sydney Force, protecting convoys through the Gulf of St. Lawrence. One significant engagement occurred on 6–7 September 1942 when her convoy was attacked by German U-boats U-165 and U-517, resulting in the sinking of multiple merchant vessels and the armed yacht Raccoon, with Truro engaging in counterattacks but without success in sinking the submarines. After the war, Truro was paid off on 31 July 1945 and transferred to the Royal Canadian Mounted Police, where she was renamed Herchmer. The vessel was sold in 1946 for mercantile conversion, emerging as Gulf Mariner, a 609 GRT merchant ship. She served in this capacity until 1964, when plans to convert her into a suction dredger failed. Subsequently abandoned on the Fraser River shore, the vessel was broken up in Canada the same year, marking the end of her maritime service.
