Attacks on this boat

24 May, 1944
A Canadian Sunderland aircraft (Sqdn 422/R) attacked the boat. The aircraft was shot down but not before wounding 3 men, including the Commander, Oblt. Wolfgang Leu. As the boat crash dived Leu got both his wounded men down but did not manage to get down into the tower himself. He slammed the hatch down as the boat dove and was drowned. The boat reached Trondheim, Norway under the command of the I WO on the 26th. (An American submarine commander received the Medal of Honor for the very same act in the Pacific).

24 May, 1944
