The Battle of the Gulf of St. Lawrence, which saw German U-boats penetrate the Cabot Strait and the Strait of Belle Isle to sink 23 ships between 1942 and 1944, marked the only time since the War of 1812 that enemy warships inflicted death within Canada's inland waters. The battle advanced to within 300 kilometres of Québec City. A war that pervaded people's lives but was still somehow remote, had become immediate, threatening, and very real. This site outlines the story of this battle.
