German submarine U-320

German submarine U-320 was a Type VIIC/41 U-boat of the Nazi German Kriegsmarine during World War II.

She carried out just two patrols, but did not sink any ships.

The boat was sunk in May 1945 by a British aircraft and scuttling in the North Sea, the last to be sunk by direct action.

Service history
The submarine was laid down on 1 December 1942 by the Flender Werke yard at Lübeck as 'werk' 320, launched on 6 November 1943 and commissioned on 30 December under the command of Oberleutnant Siegfried Breinlinger.

She served with the 4th U-boat Flotilla for training, from 30 December 1943 to 1 April 1944 and the 5th flotilla for operations until her sinking on 8 May 1945.

1st patrol
U-320 departed Kiel on 16 April 1945 and arrived in Horten (south of Oslo), on the 21st.

2nd patrol and loss
The boat left Horten on 27 April 1945. On 8 May she was badly damaged by depth charges dropped from a British Catalina of No. 210 Squadron RAF. The battered submarine managed to surface off the Norwegian coast, where she was scuttled.
