ww2dbaseU-40 was commissioned into service in Feb 1939. In her short career, she had two commanding officers, Kapitänleutnant Werner von Schmidt and Kapitänleutnant Wolfgang Barten. She conducted two war patrols. In Oct 1939, she struck a mine in the Strait of Dover and sank. 39 were killed during the sinking and 9 survived. 6 of the survivors would die of wounds or exposure, however. The 3 survivors were rescued and taken prisoner aboard destroyer HMS Boreas.

On 10 February 1944, HMS Boreas (Lt. Cdr. Michael W. Tomkinson, RN), the ‘B Class’ destroyer which picked up the survivors from U-40, was loaned to the Greek Navy and renamed RHN Salamis. She was returned to the Royal Navy in 1951 for decommissioning.

That would have to be one of the shortest operational careers of any U-Boat in WW2 - 7 weeks and 2 patrols.
