On 6 June, "Hauptmann" Adolf Galland was appointed "Gruppenkommandeur" (group commander) of III. "Gruppe", replacing "Major" Ernst Freiherr von Berg. The Armistice of 22 June 1940 ended the Battle of France and III. "Gruppe" was ordered to Mönchen-Gladbach for a period of maintenance and replenishment. On 21 July, III. "Gruppe" was moved to an airfield at Caffiers in northern France, close to the English Channel in preparation for the Battle of Britain. Schöpfel claimed his first two aerial victories during the Battle of Britain on 8 August. In a mission to Dover, clearing the airspace ahead of Junkers Ju 87 dive bombers from "Luftflotte" 3 (Air Fleet 3) attacking Allied convoy "Peewit" during the "Kanalkampf", Schöpfel claimed a No. 600 Squadron Bristol Blenheim bomber and a No. 65 Squadron Spitfire destroyed. The Blenheim crashed into the sea off Ramsgate. Flying Officer D. N. Grice, Sergeant F. J. Keast and A.C.J.B.Q Warren were all killed in action. Schöpfel had originally misidentified the Blenheim and filed the claim over a Handley Page Hampden bomber. On 12 August, one day before "Adlertag", he claimed a Spitfire shot down near Folkestone. The downed aircraft belonged to either No. 151 or No. 501 Squadron, but neither squadron operated the Spitfire at this time. No. 151 reported the loss of three Hurricanes, and one pilot, while No. 501 lost two fighters and one pilot killed—the surviving pilot being Squadron leader A. L. Holland. The day after "Adlertag", he claimed a Hurricane from either No. 32 or No. 615 Squadron. This claim was not confirmed. 32 Squadron suffered damage to three Hurricanes in force-landings after aerial combat; all pilots unhurt. British sources attribute the loss of two pilots and two Hurricanes from 615 Squadron to Messerschmitt Bf 110s.
