He was credited with eight confirmed aerial victories, comprising 1 enemy aircraft captured, 1 destroyed, 1 'forced to land' and 5 'driven down'. Rees and his gunner, Flight Sergeant James McKinley Hargreaves, were the only two airmen to become aces flying the earliest purpose-built British fighter airplane, the Vickers Gunbus.
