Attacks on this boat and other events
26 Sep 1940
A few hours before reaching base at Lorient, U-138 encountered the British submarine HMS Tribune which fired four torpedoes at her. None hit the U-boat, which docked shortly afterwards.
1 recorded attack on this boat.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-138 did not suffer any casualties (we know of) until the time of her loss.
There was another U-138 in World War One
That boat was launched from its shipyard on 12 Jan 1917 and commissioned into the Imperial Navy on 26 Mar 1918. The Naval war in WWI was brought to an end with the Armistice signed on 11 Nov, 1918. Read about SM U 138 during WWI.
