Sunk on 30 April 1945 in the North Atlantic east of Cape Hatteras, USA, in position 36.34N, 74.00W, by depth charges from the US patrol frigate USS Natchez and the US destroyer escorts USS Coffmann, USS Bostwick and USS Thomas. 52 dead (all hands lost). (Axel Niestlé, January 1990).
Because U-879 was lost while operating in the same area as U-857 in April 1945 it is unclear which U-boat was responsible for three attacks on merchant ships between 14 and 23 April and which one was sunk by the depth charge attacks carried out by four US warships on 30 April.
Another possibility is that one of them was sunk by a US blimp (airship) that made a claim of dropping a homing torpedo on a submarine on 18 April 1945.
Previously recorded fate
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-879 did not suffer any casualties (we know of) until the time of her loss.
