The submarine was sent by Germany at the end of the war to cause havoc along the East Coast of the United States, in an attempt to repeat the success of Operation Drumbeat. However, she saw no combat in that mission and did not sink or damage any allied ships during the war. Her captain, Kapitanleutnant Thilo Bode, formally surrendered her on 14 May 1945 at Fort Miles near Lewes, Delaware. This was the first instance of a foreign surrender occurring within the United States since the War of 1812. After surrendering, the submarine was used for publicity in war bond drives. After being used for torpedo practice near the New England area, she was scuttled by the U.S. Navy on 21 November 1947. ==Notes==
