Final location

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 problem with the latrine. This is not true, but U-1206, a much larger boat, did suffer from such a problem 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.

There was another U-120 in World War One
That boat was launched from its shipyard on 20 Jun 1918 and commissioned into the Imperial Navy on 31 Aug 1918. The Naval war in WWI was brought to an end with the Armistice signed on 11 Nov, 1918. Read about SM U 120 during WWI.
