| History | HMS Spearfish (Lt.Cdr. John Hay Forbes, DSO, RN) sailed from Rosyth on 31 July 1940. The next day she was hit by 1 torpedo from the German submarine U-34 and sank about 130 nautical miles north-east of Aberdeen, Scotland in position 58º07'N, 01º32'E. U-34 was returning from her last patrol as a combat boat. She had only one torpedo remaining after a succesful patrol (already 4 ships sunk). The u-boat picked up the sole survivor from HMS Spearfish.
