Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-55 did not suffer any casualties (we know of) until the time of her loss.
There was another U-55 in World War One
That boat was launched from its shipyard on 18 Mar 1916 and commissioned into the Imperial Navy on 8 Jun 1916. The Naval war in WWI was brought to an end with the Armistice signed on 11 Nov, 1918. Read about SM U 55 during WWI.
