For two years, U-boats patrolled the inland Canadian waterway of the St. Lawrence River. During that time, they would sink multiple ships, take the lives of dozens of Canadian sailors and put a country on edge as the war reached the home front. Today, I look at the Battle of the St. Lawrence, a time when Canada had to defend its waters against a silent killer. It is a story of success and failures, spies and the tragic killing of civilians.
