From Southend, Essex, Eustace Osborne Grenfell crashed and broke his leg on the day he scored his last
victory. He became a Group Captain on 1 July 1938 and retired from the Royal Air Force on 17 February 1942. As he isn't listed in the 1986 RAF Retired List, it seems likely that he died between 1957 and 1986.
Military Cross (MC)
Lieutenant (temporary Captain) Eustace Osborne Grenfell, Royal Artillery and Royal Flying Corps.
For conspicuous gallantry and skill. He attacked single-handed and brought down three Fokker aeroplanes.
Captain Grenfell has shown great bravery and initiative at all times.
