On 4 October 1944, the German submarine U-1227 torpedoed the Canadian frigate HMCS Chebogue, which was escorting a westbound convoy.

The acoustic torpedo homed in on the sound of Chebogue's propellers, and its exploding warhead blew off 10 metres of the ship's stern, killing seven sailors. In this photograph, an officer (left) examines the extensive damage that nearly sank the frigate and left it unable to move under its own power. Towed by a series of ships, Chebogue reached Wales after eight days. Declared a total loss, the frigate was not repaired.
