Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-4 did not suffer any casualties (we know of) until the time of her loss.

There was another U-4 in World War One
That boat was launched from its shipyard on 18 May 1909 and commissioned into the Imperial Navy on 1 Jul 1909. The Naval war in WWI was brought to an end with the Armistice signed on 11 Nov, 1918. Read about the U 4 during WWI.
