201 RCSCC GRILSE is named after HMCS GRILSE (SS-71).  She was a US Submarine called USS BURRFISH, commissioned on 13 September 1943.  BURRFISH conducted six War Patrols during the Battle of the Atlantic in World War II.  She continued to serve in the US Navy before being commissioned into the Royal Canadian Navy as HMCS GRILSE on 11 May 1961.  She served Canada for over eight years until 2 October 1969 when she was paid off.  On 19 November 1969, she was sunk as a target.




The Battle of the Atlantic was one of the longest running battles in history, beginning in 1939 and not ending until 1945.  For six years, the Royal Canadian Navy (RCN), Canadian Merchant Navy, and Royal Canadian Air Force (RCAF) played a vital role in keeping the supply lines to Europe open and protected.


By the end of the war, over 2000 RCN members and over 700 RCAF members were killed in maritime operations.  In the end, the Battle of the Atlantic was won by the Allies with massive help from Canada.


On the first Sunday of every May, we recognize the sacrifices that were made in this theatre.  For more information on Canada's contribution to the Battle of the Atlantic, visit Veterans Affairs Canada.
