Ronald M. Keirstead

Keirstead learned to fly at the civilian Curtiss School in Toronto in 1916. He then joined the Royal Naval Air Service, Keirstead would win three more times in 1917, ending the year with an out of control win on 6 December. His DSC would be gazetted on 22 February 1918. The big day of Flight Commander Keirstead's career as an ace came on the afternoon of 21 March, when he drove down a Pfalz D.III fighter, destroyed another, and teamed with a Belgian Spad to destroy yet another Pfalz. He would score two more single victories after his squadron was redesignated 204 Squadron RAF, rounding off his tally on 12 June 1918. In summary, Keirstead was credited with destroying six enemy airplanes, including three shared wins; driving six more down out of control; and sharing in the capture of a Rumpler. ==Post World War I==

On 24 September 1917, he engaged single-handed four enemy aeroplanes, of which two were destroyed by him. On 21 October 1917, during an engagement between a British and a German formation, he attacked one of the enemy scouts and shot its port wings away from the rest of the machine. He then dived on to some enemy scouts which were attacking another of our machines and brought one of them down in a spinning nose dive. ==References==
