In March 1918, he joined 84 Squadron under Sholto Douglas, flying the S.E.5a in combat. He was wounded for the second time on 10 May 1918. Promoted to Captain on the 8 September 1918, he commanded "B" flight until the Armistice. Upon his return to to England, Falkenberg transferred to the Royal Canadian Air Force and served as a flight commander with 1 Fighter Squadron until his discharge on 18 October 1919.
