Battle of the Atlantic
The Battle of the Atlantic was the longest battle of the Second World War and was fought at sea from 1939 to 1945. Much of the burden of fighting the battle fell to the RCN which, at the outbreak of the war, was comprised of only six destroyers and a handful of smaller vessels.
We honour our past by remembering the tremendous efforts Canadian sailors made in fulfilling their commitment to secure Allied victory, and we salute the RCN’s resolute path forward in remaining committed to the safety, security and defence of Canada at home and abroad.
