Previously recorded fate (Last revised by FDS/NHB during June 1987). More on revised fates

The attack by a British Liberator aircraft (RAF 120/H) on 15 Oct, 1942 in position 53.58N, 33.43W, formerly credited with sinking this boat was instead against the U-615, causing no damage.

General notes on this boat

There was going to be another loss around convoy SC-104 as U-353 was sunk the next day.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-661 did not suffer any casualties (we know of) until the time of her loss.
