Attacks on this day



On 28 Apr 1941 southeast of Iceland, in position 60.04N, 15.45W, the British corvette HMS Gladiolus depth charged a German U-boat. This was for some time thought to have sunk U-65, but the target was actually U-96, which escaped unscathed.

U-552. After torpedoing a ship in convoy HX 121 south of Iceland, U-552 was depth charged in five separate attacks from the escorting destroyers HMS Maori and HMS Inglefield, forcing the boat to remain submerged for hours until the convoy was out of range. (Blair, vol 1, page 272)


U-386. In attacking convoy ON(S) 5 the boat suffered severe damage from the escorts. (Blair, vol 2, page 293)

U-528. Damage inflicted by the escorts after U-528 attacked convoy ON(S) 5 forced the boat to break off the patrol and return to France. She was sunk nine days later. (Blair, vol 2, page 293)

U-532. In attacking convoy ON(S) 5 the boat suffered damage during an exhaustive 15 hour hunt by the escorts. (Blair, vol 2, page 293)


U-802. The target of the depth charge attack on 28 April 1944 in the Bay of Biscay west of Nantes, France in position 45.38N, 09.43W, by a British Wellington bomber (Sqdn. 612/W), formerly credited with sinking U-193, was actually U-802, which escaped undamaged. (1996-07-01, Axel Niestle)

U-473. 03.27 hrs, Bay of Biscay, outbound: the boat was attacked using the Leigh Light by Halifax Mk.II aircraft HX152 (RAF Sqdn 58/M, pilot F/L W.D.C. Erskine-Crum) after being located on radar. The aircraft dropped seven depth charges following an exchange of gunfire, which damaged the port wing. The pilot barely regained control, but brought the Halifax to St. Eval, where four cannon hits to the wing and one to the port mainplane were discovered. Despite being straddled by depth charges U-473 was not damaged. (Franks/Zimmerman)
