Attacks on this boat and other events

25 Aug 1942
1431hrs, 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 target of the attack by a British Whitley aircraft (77 Sqn RAF/V) on 3 September 1942 in position 47.55N, 10.04W, long believed to have sunk U-705, was in fact U-660, which escaped unscathed. (Sources: 1987-11-01, FDS/NHB)

2 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-660 did not suffer any casualties (we know of) until the time of her loss.
