The Lévis was a Flower class corvette built at Lauzon, MRC de Desjardins, Québec, and commissioned in May 1941. She was among the earliest of the 107 corvettes built for convoy escort duties during the war, and thus one of the most poorly equipped. The tactics, techniques and equipment for the anti-submarine battle in the north Atlantic were very much made up as they went along, gaining hard won experience. The Lévis was hit by a torpedo from U74 in the early morning of 19410919. Remarkably for corvettes, which usually sank like a stone, the Lévis stayed afloat for over 12 hours with the result that only 18 of her crew of 58 were lost, 17 of them in the initial explosion. Among them were GE Jaynes and RB White.
