24 May 1944
After shooting down one Sunderland at 14.20 hours, U-921 was sighted shortly afterwards by Sunderland DW111 (RCAF Sqn 423/S, pilot F/L R.H. Nesbitt), responding to a Mayday call, which had apparently observed the first Sunderland crash from a distance of about 12 miles (19 km). U-921 avoided the five depth charges it dropped, but strafing wounded three men, including the commander, Oblt. Wolfgang Leu. Oblt. Leu got both wounded crewmen below as the boat was diving, then closed the hatch, sacrificing himself to prevent the boat sinking. U-921 reached Trondheim on 26 May under the command of the I WO. (An American submarine commander was awarded the Medal of Honor for the selfsame act of heroism in the Pacific). (Sources: Franks/Zimmerman)
