Attacks on this boat and other events

24 May 1944
Aircraft attack, aircraft shot down: Canadian Sunderland flying boat DV990 (RCAF Sqdn 422/R, pilot F/O G.E. Holley)

14.20 hrs, off Norway: the boat was attacked while searching for U-476, which had been badly damaged by air attack earlier in the day. The Sunderland was hit by flak during the attack run and and crashed into the sea after dropping three depth charges (no damage). The crew of 12 all died.

24 May 1944
After shooting down one Sunderland at 14.20 hours, U-921 was sighted shortly afterwards by Sunderland DW111 (RCAF Sqdn 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. 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 IWO. (An American submarine commander was awarded the Medal of Honor for the selfsame act of heroism in the Pacific). (Sources: Franks/Zimmerman)
