Citation:
"During operations over enemy territory in December, 1939, this airman, as tail gunner, maintained a steady and accurate fire at all enemy aircraft that came within range. He himself shot down one Messerschmidt. This aircraft engaged the leader's aircraft at extremely close range. Corporal Bickerstaff quickly brought his guns to bear and directed a cool and accurate fire, his tracer being seen to pass directly through the pilot's position before the enemy aircraft burst into flames and crashed into the sea."
