Winston Churchill once wrote that the only thing that "ever really frightened" him during the Second World War was the threat presented by Germany's U-boats. The Battle of the Atlantic was the struggle to protect Allied ships in the North Atlantic from these marauding German submarines. Every year, Canada remembers the sacrifice made by its armed forces and merchant fleet on Battle of the Atlantic Sunday, the first Sunday in May.
This year, Canada Post will honour the Canadians who helped to keep these important shipping lanes open, with a stamp that portrays this battle fought at sea. The stamp will be available in post offices across the country on April 29, 2005.
