General notes on this boat

30 Oct 1942. The sinking boat was boarded by three men from HMS Petard who had swum over to her. Two of them went down with the wreck when it foundered, but they had managed to pass out the Enigma code machine, with the current rotor settings, and the cipher books. This allowed the Allies to read naval traffic for several weeks and crack Enigma codes thereafter.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-559 did not suffer any casualties (we know of) until the time of her loss.
