German submarine U-519

German submarine U-519 was a Type IXC U-boat of the Nazi German Kriegsmarine during World War II. She was laid down on 23 June 1941 at the Deutsche Werft yard in Hamburg as 'werk' 334, launched on 12 February 1942 and commissioned on 7 May 1942 under the command of Kapitänleutnant Günter Eppen.

After training with the 4th U-boat Flotilla, U-519 was transferred to the 2nd U-boat Flotilla for front-line service on 1 November 1942.

1st patrol
The U-boat left Kiel on 17 October 1942, moved through the gap between Iceland and the Faeroe Islands into the Atlantic Ocean and patrolled the vicinity of the Azores, joining the wolfpack Westwall between 8 November and 16 December. However she had no successes. She arrived at Lorient in occupied France on 29 December after 74 days at sea.

2nd patrol
The boat departed Lorient for the last time on 30 January 1943. She has been posted missing since 31 January 1943. She was previously thought to have been sunk by "Tidewater Tillie," a B-24 Liberator of the 2d Antisubmarine Squadron, about six hundred miles west of Lorient.
