Attacks on this boat and other events
25 Aug 1942
14.31 hrs, mid Atlantic south of Greenland: HNoMS Potentilla and HMS Viscount were rejoining convoy ONS-122 when HNoMS Potentilla obtained a radar contact. Three minutes later (and not previously visible due to foggy conditions), U-660 was sighted. Fearing damage to herself from ramming, HMS Viscount forced the U-boat to dive by opening fire, and after an abortive initial approach dropped five heavy depth charges. HMS Viscount then attempted a Hedgehog attack, but lost Asdic contact, as did HNoMS Potentilla. They were unable to regain contact and returned to the convoy after dropping single depth charges for about an hour. U-660 was not damaged. (Sources: ADM reports, KTB U-660)
3 Sep 1942
The attack by a British Whitley aircraft (77 Sqdn RAF/V) on 3 Sept. 1942 in position 47.55N, 10.04W, long believed to have sunk U-705, was in fact on U-660, causing no damage. (Sources: 1987-11-01, FDS/NHB)

Men lost from U-boats
