HMCS Charlottetown was a Flower-class corvette constructed for the Royal Canadian Navy during the Second World War. Laid down on June 7, 1941, at Kingston Shipbuilding Ltd. in Kingston, she was launched on September 10, 1941, and commissioned on December 13, 1941, in Quebec City. Shortly thereafter, she arrived at her homeport of Halifax, Nova Scotia. The vessel measured approximately 205 feet in length with a beam of about 33 feet, typical of Flower-class corvettes, built for escort and coastal auxiliary roles. Originally designed based on a whaling ship hull, these ships were adapted for open-sea escort duties, although Canadian corvettes like Charlottetown were initially more suited for coastal auxiliary tasks, including minesweeping, before modifications improved their seaworthiness in open waters. HMCS Charlottetown served primarily with the Western Local Escort Force until mid-July 1942, after which she transferred to the Gulf Escort Force. Her service involved escorting convoys along the Quebec City to Sydney route, playing a role in the Battle of the St. Lawrence, a critical campaign protecting vital supply lines. Her service was cut short on September 11, 1942, when she was torpedoed and sunk by the German U-boat U-517, approximately 6 nautical miles off Cap Chat in the St. Lawrence River. The attack occurred as she was returning to base with the minesweeper HMCS Clayoquot, after escorting convoy SQ-35. The U-boat struck her aft with two torpedoes, causing her to sink rapidly. Despite most of her crew escaping, the sinking resulted in the loss of her captain, Lieutenant Commander John W. Bonner, and eight other crew members, out of a total complement of 64. Some crew members perished in the water when her depth charges detonated as she sank. HMCS Charlottetown's short but active wartime service exemplifies the vital role of Canadian corvettes in WWII Atlantic and Gulf convoy protection, as well as the dangers faced by these small warships in the Battle of the St. Lawrence.
