Sunk 9 Feb 1945 in Kiel Bay, in position 54.31N, 10.18E, by a mine. 48 dead (all hands lost).

Loss position

The fate above, the usual given, is most probably incorrect according to information I have received. When the boat was raised a dud rocket was found. This proves that the boat was sunk by a rocket-equipped fighter plane on or near this date, possibly a Typhoon.

The boat was raised in January 1953 and broken up.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-923 did not suffer any casualties (we know of) until the time of her loss.
