U-110 was a German IXB type submarine, which in May 1941 was captured south of Iceland, intact by a British fleet after being forced to the surface and a British Destroyer (HMS Broadway) made to ram the submarine. Fearing for the crew, and believing the submarine would be sunk, the submarine's commander ordered everyone to abandon the submarine, leaving everything behind. However, the commanding British destroyer ordered the destroyer to abort the ram. The survivors were picked up and a boarding party entered the submarine and removed code books, signal books and charts. The code and signal books proved invaluable in decoding the enigmacodes used by the German navy during the Second World War. Fritz Lemp (the commander of U-110) was never seen again. Suggestions that he was shot by the boarding party are rebuked by the leader of the boarding party who suggests that the German commander, ashamed at his error of judgement in allowing his vessel to be captured intact, committed suicide in the water. The submarine was allowed
to sink the next day so that the German's would not know of the capture, and the loss of essential code and signal books. Research U-110
