The History Behind the Autograph
During the dramatic capture of U-505 by a U.S. Navy task force on June 4, 1944, Goebeler was the crewman who manually opened the main sea valve (the "plug") in a desperate attempt to scuttle and sink the submarine so it wouldn't fall into enemy hands. U.S. boarding parties miraculously managed to rush aboard, close the valve, cap the leak, and capture the vessel entirely intact.
Decades after the war, Goebeler relocated to the Chicago area, where U-505 is permanently preserved at the Museum of Science and Industry. He spent much of his later life giving unofficial tours of his old boat and warmly signing these exact multi-photo displays for military history enthusiasts.
