U-Boat Killer , first published in 1956, is an exciting account of a British Royal Navy destroyer in World War II. Tasked with guarding vital Atlantic convoys and later commanding 'Hunter/Killer' groups, author Captain Donald MacIntyre (1904-1981) became a near-legend during the war, with 7 destroyed German submarines to his credit, as well as several U-boat captures. He also survived a torpedo hit, and, after ramming a U-boat, successfully piloted the damaged ship back to safety.
