The submarine was laid down on 13 February 1943 by the Flender Werke yard at Lübeck as 'werk' 322, launched on 18 December and commissioned on 5 February 1944 under the command of Oberleutnant zur See Gerhard Wysk.
2nd patrol and loss
The boat left Horten on 15 November 1944, heading for the 'gap' between the Faroe and Shetland Islands and passing west of Ireland. On 23 December, she sank the Dumfries off St Catherine's Point, Isle of Wight in the English Channel. On the 29th, seven miles off the Portland lighthouse near Weymouth, she attacked the Arthur Sewall and the Black Hawk, causing both vessels to be declared a total loss. She was sunk on the same day by depth charges dropped from the Canadian frigate HMCS Calgary.
Fifty two men died; there were no survivors.
Previously recorded fate
The wreck has been found; although it was originally thought to be that of U-772, it has been identified as U-322.
