The boat attacked convoy ON-4 and sank the convoy escort HMS Picotee but missed a freighter he also fired on. The other convoy escorts counterattacked the boat and held her down while the convoy escaped. (Sources: Blair, vol 1, page 335)

17 Oct 1941
At 05.49 hours, 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 began to chase U-568 and fired six rounds from the 4in gun but missed. At 06.02 hours, the U-boat fired its stern torpedo which was seen on HMCS Pictou to miss 15 feet on port and shortly thereafter crash dived after turning sharply to starboard. U-568 was already on 40 meters when the first pattern of five depth charges detonated at the diving spot and also the second pattern of five charges detonated too far above the U-boat to cause any damage. No further attacks were carried out because the Asdic of HMCS Pictou broke down and HMS Highlander and HMCS Wetaskiwin were unable to obtain a contact, probably because U-568 already surfaced 45 minutes later with two corvettes in sight and escaped on the surface.

9 Jan 1942
The attack by a Sunderland (RAF-Sqdn 230/X) aircraft on 9 Jan, 1942 in position 32.22N, 26.54E believed to have sunk the U-577 was actually against the U-568 causing minor damage to that boat. (Sources: 1990-11-01, FDS/NHB)
