Attacks on this boat and other events
12 Aug 1941
U-568 attacked convoy ON-4 ON-4 southeast of Iceland, sinking the British corvette HMS Picotee, but missing a freighter. The other convoy escorts counterattacked and held the boat down while the convoy escaped. (Sources: Blair, vol 1, page 335)
17 Oct 1941
At 05.49 hrs, mid Atlantic, south of Iceland: the boat was sighted by HMCS Pictou on the port side of the convoy SC-48 and tried to escape at full speed on the surface into a rain squall. The corvette immediately pursued U-568, and fired six rounds from the 4in gun, all of which missed. At 06.02 hours, the U-boat fired a stern torpedo, which was seen on HMCS Pictou to pass 15 feet to port, and the boat dived shortly thereafter after turning sharply to starboard. U-568 had reached 40 metres when the first pattern of five depth charges detonated at the diving point, and the second pattern of five charges detonated too shallow to cause any damage. No further attacks were carried out because HMCS Pictous Asdic broke down and HMS Highlander and HMCS Wetaskiwin were unable to obtain a contact. U-568 had already surfaced 45 minutes after the attack, sighted two corvettes, and escaped on the surface. (Sources: KTB U-568/ADM 237-164)
9 Jan 1942
The attack by a Sunderland aircraft (RAF Sqdn 230/X) on 9 Jan. 1942 off Sidi Barrani, Egypt in position 32.22N, 26.54E, believed to have sunk U-577, was actually against U-568, and caused only minor damage. (Sources: 1990-11-01, FDS/NHB)
3 recorded attacks on this boat.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-568 did not suffer any casualties (we know of) until the time of her loss.
