HMCS Sorel was a Flower-class corvette built for the Royal Canadian Navy during the Second World War, primarily serving as an ocean escort in the Battle of the Atlantic. Constructed by Marine Industries Ltd. in Sorel, Quebec, she was ordered on 22 January 1940, laid down on 24 August 1940, and launched on 16 November 1940. She was commissioned at Sorel on 19 August 1941. The vessel featured two water tube boilers, which supplied power for her propulsion and operational needs. Designed as a small, versatile warship, Sorel’s class was based on a whaling ship design, reflecting the reactivation of the corvette class by Winston Churchill in the late 1930s for escort duties. Canadian Flower-class corvettes like Sorel were initially intended for coastal auxiliary roles, often fitted with minesweeping gear, but were later modified for better performance on the open sea. Sorel underwent three major refits during her service: the first in January 1942 at Leith due to mechanical issues; the second between October 1942 and February 1943 at Liverpool, Nova Scotia, Pictou, and Halifax; and a final overhaul beginning in November 1943, during which her forecastle was extended. Her wartime service included initial deployment with Sydney Force, before transferring in November 1941 to Newfoundland Command for convoy protection between St. John’s and Iceland. After experiencing mechanical problems, she was sent to the UK for repairs in January 1942. Subsequently, Sorel joined the Western Local Escort Force in May 1942, serving as a convoy escort. She also functioned as a training ship in early 1943 at Digby, St. Margaret's, and Pictou, and temporarily joined the Mid-Ocean Escort Force C-3 in September 1943. Returning to active duty in mid-1944, she was assigned to the Western Escort Force’s group W-4 for the remainder of the war. Decommissioned on 22 June 1945, Sorel was sold to the Yugoslav Navy on 16 November 1945. Her post-war service was short-lived; while manned by a Yugoslav crew, she ran aground on the southern point of Henry Island on 13 December 1945. Sorel’s service record underscores her role in Atlantic convoy protection and her adaptability through multiple refits and operational roles during wartime.
