German U-Boat U 534 was raised from the sea bed in 1996, and the wreck and the artefacts, including an enigma machine, were saved. U-534 was attacked and sunk by two Royal Air Force Liberator bombers in the Kattegat sea between Denmark and Sweden on 5 May 1945. Discovered by a Danish wreck diver in 1986 and raised from the seabed by a Dutch salvage company in 1993, she later was moved to Birkenhead, England, where she became a star exhibit at the Warship Preservation Trust’s Birkenhead Docks Museum.
