In North America, we think of the Second World War as being fought far away (except for the Japanese sneak attack on Pearl Harbor). Few know that German U-boats prowled largely unchallenged up and down the St. Lawrence River, sinking unwary Canadian military and Allied merchant vessels in an attempt to stop the flow of goods, troops and armaments to war-ravaged Britain. Fewer still know that prior to the war, Hitler tried to purchase Anticosti Island, located at the mouth of the St. Lawrence, from a wealthy French chocolate-bar manufacturer. Victory in the St. Lawrence tells the riveting true story of how shortsighted government priorities and advanced German submarine technology allowed the Nazis to stalk shipping in Allied home waters. Although much of the Second World War is well documented, missing chapters still surface even now, a half century later -- stories of chilling events that might have changed the course of history. Victory in the St. Lawrence reveals how courageous, independent-minded heroes defended North America deep within its defenses.
