Attacks on this day


U-62. U-62 encountered an enemy submarine in the North Sea. The latter launched torpedoes, but the U-boat was able to dodge them.


U-441. Aircraft attack, aircraft shot down:
British Sunderland EJ139 (228 Sqdn RAF/L, pilot F/O H.J. Debnam)

20.50 hrs, Bay of Biscay: the flak boat inflicted fatal damage on the Sunderland during its attack run, which nonetheless managed drop five depth charges before crashing with the loss of the crew of 11. U-441 was left with severe damage and one man wounded by strafing, and had to return to base. This was the first 'kill' by a flak boat. (Franks/Zimmerman)

U-523. 11.22 hrs, Bay of Biscay, outbound: six bombs from a British Whitley bomber (10 OTU RAF/J, pilot Sgt C.S. Chatton) caused severe damage and the boat was forced to return to base at Lorient. (Norman Franks)

U-178. 06.05 hrs, off Capetown, South Africa: the boat was attacked by a Dutch Catalina flying boat (RAF Sqn 321/Z) while tracking a small convoy. Three bombs dropped. No damage, but the convoy escaped. (Rohwer / Blair, vol 2, page 301)


U-921. Aircraft attack, aircraft shot down:
Canadian Sunderland flying boat DV990 (RCAF Sqn 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 in an 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.


U-476. Following crippling damage from an attack by a British Catalina flying boat (210 Sqn RAF/V) at 07.18 hrs on this day, the boat was scuttled on 25 May. U-990 saved the commander and 20 men of the crew, but 34 went down with the boat due to bad weather that made the rescue operation difficult. U-990 was then herself sunk by a B-24 Liberator aircraft on 25 May. Three men from U-476 were lost.

U-921. 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). (Franks/Zimmerman)

U-736. Aircraft attack, aircraft shot down:
British Wellington bomber (612 Sqn RAF/L, pilot F/O K.M. Davies)

Bay of Biscay, inbound: the boat shot down the Wellington (killing the crew of six) shortly after being left unable to dive following an attack by a British B-24 Liberator (RAF Sqn 224/C, pilot F/L E.W. Lindsay). The badly damaged U-736 was later escorted into Lorient by five minesweepers.
