to Moorsele Airfield where the unit was closer to the RAF "Circus" routes. The infrastructure at Moorsele was ideal for the planned transition to the then new Focke Wulf Fw 190 fighter aircraft which began arriving in July. On 6 July, the RAF flew another "Circus". No. 35 targeted Lille and the Fives-Lille engineering company. In defense of this attack, Adolph shot down a Spitfire from No. 74 Squadron. On 23 July, JG 26 claimed four Blenheim bombers shot down from No. 21 Squadron off the Scheldt Estuary and Ostend, including Adolph's 21st aerial victory. On 16 August, Adolph claimed aerial victories numbering 23 and 24 of World War II while defending against "Circus" No. 75. That day, he shot down a No. 602 Squadron Spitfire northwest of Boulogne and a No. 602 Squadron north of Marquise. On 18 September 1941, elements of JG 26 escorted a German tanker through the English Channel. The tanker came under attack by three Blenheim bombers just off the coast near Blankenberge. The bombers were escorted by Spitfire fighters from No. 41 Squadron and Hurricane fighters from No. 615 Squadron. Adolph headed a flight of eight Fw 190 from II. Gruppe in defense of the tanker. Following the attack on the tanker, one Blenheim bomber was claimed shot down by a German pilot. Adolph, while observing the crashed bomber, was shot down and killed in his Fw 190 A-1 (Werknummer 0028—factory number) northwest of Ostend. The British flying ace F/O Cyril Babbage of No. 41 Squadron is believed to have shot down Adolph. Adolph's Fw 190 was the first of its kind to be lost in aerial combat. Adolph's successor as Gruppenkommandeur was Hauptmann Joachim Müncheberg who took command of II. Gruppe on 19 September. On 12 October 1941, his body was washed ashore near Knokke, Belgium and was interred at the Lommel German war cemetery. Summary of career Aerial victory claims Author Spick lists him with 28 aerial victories, claimed in 79 combat missions. That are three victories more than authors Obermaier, Caldwell, Prien, Stemmer, Rodeike and Bock attribute him with. Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for more than 21 aerial victory claims, plus four further unconfirmed claims. This number includes one claim during the Spanish Civil War and 20 on the Western Front of World War II.
