He was commissioned as a Pilot Officer and flew Hurricanes with 85 Sqn. Initially based in France as part of the Air Component of the BEF, the squadron was withdrawn during the Battle of France and then operated from Debden. Pilot Officer Peter Gossage was killed on 31 May 1940 and is buried near his family, in Buxted.
