Statement of Significance

Description of Historic Place

HMCS Sackville National Historic Site of Canada is a Canadian built, Flower Class Corvette currently berthed at a wharf in downtown Halifax, Nova Scotia. She is an armed, steam-powered ship with a single propeller. These small, warships were used as convoy escort vessels by the allies during the Second World War. The official recognition refers to the vessel herself.

Heritage Value

HMCS Sackville was designated a national historic site of Canada in 1988 because:
- it is a representative example of a Flower Class Corvette;
- of the part that she played in the Battle of the Atlantic.

HMCS Sackville is one of the last Flower Class Corvettes known to exist. Designed for mass production in small shipyards, they were based on a British Admiralty design patterned after a whale-catcher. This class of ship played a major role in the Battle of the Atlantic. In December 1941, HMCS Sackville entered service escorting convoys between Newfoundland and Northern Ireland. On the night of August 3-4, 1942, while escorting an eastbound convoy in thick fog, HMCS Sackville engaged three German U-boats. Lieutenant Alan Easton and his crew seriously damaged one submarine, hit another with gunfire, and depth charged a third. This action won the Distinguished Service Cross (DSC) for Lieutenant Easton and commendations for the crew. After seeing action again in September 1943, HMCS Sackville was redeployed as an officer training ship in 1944, and laid up in reserve in 1945. Recommissioned in 1952 HMCS Sackville then spent the following 30 years supporting oceanographic, hydrographic, and fisheries research. The ship retired from the Royal Canadian Navy in 1982 and was transferred to the Canadian Naval Corvette Trust in 1983. Now restored to her 1944 configuration, HMCS Sackville is open to the public.
