The name "Battle of the Atlantic", coined by Winston Churchill in 1941, covers a campaign that began on the first day of the European war and lasted for six years, involved thousands of ships and stretched over hundreds of miles of the vast ocean and seas in a succession of more than 100 convoy battles and perhaps 1,000 single-ship encounters. Tactical advantage switched back and forth over the six years as new weapons, tactics and counter-measures were developed by both sides. The British and their allies gradually gained the upper hand, driving the German surface raiders from the ocean by the end of 1942 and decisively defeating the U-boats in a series of convoy battles between March and May 1943. New German submarines arrived in 1945, but they were too late to affect the course of the war.

When war broke out, Canadian navy personnel amounted to just 3,684 officers and crew, including RCN Reserve and Volunteer Reserve.

Within a year, more than 10,000 had mustered in and by 1944, Its numerical strength peaked at 95,705 officers and men serving in 378 warships. In total, 110,000 men and women served in the RCN during the War, every one of them a volunteer.

This recruitment represents an amazing fifty-fold in pre-War strength, compared to a twenty-fold increase of the US Navy, a fourteen-fold increase of the Royal Australian Navy and an eight-fold increase of the Royal Navy.

The Merchant Navy lost 1,629 Canadians and Newfoundlanders, or others who served on ships registered in Canada or Newfoundland. It includes the names of eight women. Many other Canadians, whose names are unknown, died serving on ships of Allied merchant navies. Also, 198 Canadian seamen were taken prisoner when their ships were captured or sunk, often in the very early years of the war. Many spent more than four years interned and eight died as prisoners of war or during repatriation.



The RCN lost 1,965 men and 24 ships during the War, most of them in the Atlantic.

The following is a list of HMC ships that were lost.

We salute those ships and all who sailed in them...

Accompanying the Fraser was the Canadian destroyer HMCS Restigouche and the British cruiser HMS Calcutta. In rough seas and poor visibility, the captain of the Fraser decided that the three ships should move closer together and ordered a turn to port in order to bring his ship behind HMS Calcutta. In doing so the two ships collided, the bow of the heavier Calcutta sliced into the side of the Fraser with such force that the lighter vessel was cut into three pieces. Forty-five crewmembers were killed and nineteen men from the Calcutta lost their lives.
