This plaque is part of a campaign started in 2020 by the Royal United Services Institute of Regina, a local organization of civilians and retired military personnel, to install a series of twelve commemorative plaques around the cenotaph. It was unveiled on 8 August 2022. The plaques explain Canada's wartime history.
HMCS Regina was a revised Flower Class Corvette named for the city of Regina, and served in the Second World War. She was designed as a convoy escort vessel, with a length of 62.5 metres, a 102 mm gun, various machine guns, a hedgehog mortar, 40 depth charges, sonar and radar. Her maximum speed was 16 knots (30 km/h).
Her crew of 85 served in the North Atlantic and Mediterranean, escorting convoys and supporting the invasion of North Africa and the D-Day landings. She was credited with sinking the Italian submarine Acorto off the coast of Algeria on 8 February 1943. On 8 August 1944, while rescuing the crew of a damaged American Liberty Ship off the coast of Cornwall, England, she was struck by a torpedo from the German submarine U-667 and sank with the loss of 30 crew members. HMCS Regina was awarded five Battle Honours.
