From the Royal Engineers, Lieutenant Herbert Edward Oscar Ellis, the son of Herbert and Caroline Ellis, transferred to the Royal Flying Corps in 1916. He received Royal Aero Club Aviator's Certificate 3829 on a Maurice Farman biplane at Military School, Birmingham on 2 November 1916. On the evening of 4 May 1917, after shooting down two German scouts over the aerodrome at Douai, he was attacked by a third Albatros D.III. During the battle that followed, his Nieuport's machine gun ran out of ammunition. The fight ended when Ellis pulled a Colt semi-automatic pistol from its holster, fired seven rounds and shot down his opponent. On 6 May 1917, Ellis was injured in a crash that ended his career as a fighter pilot.
