The Guysborough was a Bangor class minesweeper built at North Vancouver, British Columbia, and commissioned in 1942. She played an active part in the D-Day invasion, helping to sweep the approaches to the American beaches in Normandy. Late in the war the Guysborough was on a somewhat leisurely patrol in the area of l’Île d’Ouessant west of Brest, Finistère, France, when she was hit in the stern by an acoustic torpedo from U878. Less than an hour later she took a second torpedo amidships and was soon on the bottom, the last Canadian vessel lost overseas 19450317. Only two of the crew of 91 were killed by the explosions, but another 50 were to perish of hypothermia before they were rescued by two Royal Navy frigates the next morning. Among the casualties were GF Adam, GT Gray, OB Konsmo, A Neufeld and RG Stevenson.
Interestingly, a Spanish trawler with “a suspicious amount of electronic gear” and suspected of having played a part in the Guysborough’s sinking was chased out of the area by HMS Loring. Obviously the trawler picked up the body of at least one Canadian sailor since GF Adam is buried in the British cemetery at Bilbao, Spain.
