German Submarine U-110 (1940)

German submarine U-110 was a Type IXB U-boat of the German Kriegsmarine that operated during World War II. U-110 was captured by the Royal Navy on 9 May 1941 which provided a number of secret cipher documents to the British. U-110's capture, later given the code name "Operation Primrose", was one of the biggest secrets of the war, remaining secret for seven months. President Franklin D. Roosevelt was only told of the capture by Winston Churchill in January 1942.
