General notes on this boat
The to-become Oblt. z. S. Alfred Radermacher was from 09.40 to 04.42 the Obersteuermann on U-96 (Buchheim described him in his novel Das Boot). Later he became an officer and Commander of U-120 and U-393.
Sunk by a toilet?
In many sources it is stated that this boat was lost due to a toilet problem. This is not true but U-1206, a much larger boat, did have similar problems that helped to contribute to its loss in April 1945.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-120 did not suffer any casualties (we know of) until the time of her loss.
