Adolphe Pégoud scores his fourth and fifth aerial victories, becoming history ’s first ace, although the designation is not widely known or accepted. Pegoud had been a pre-war daredevil pilot and a publicist of his own efforts to demonstrate aviation to the public. The French newspapers described him as a “Volant l’As” (Flying Ace). A sixth victory follows on July 11, but on August 31 Pegoud is killed in an air-to-air encounter with one of the German students he taught before the war, Corporal Walter Kandulski.
