The Secret Capture

1st edition dust jacket Nice Copy 8vo. 156pp., b/w pls., maps, index, For fifteen years after the end of the war all official Admiralty records showed the German submarine U 110 as sunk on 9 May 1941 by the surface escorts of convoy OB.318; this was a deliberate deception, as the U-boat was actually captured and its contents fully investigated before being allowed to sink a day later, a fact skilfully kept from even the survivors of the submarine's crew. The reason for the secrecy was that the U-boat gave up valuable codebooks, charts, ciphers and, most significantly, a complete and undamaged Enigma machine.
