one hangar was left operational at Kenley. The low-level raid put the airfield out of commission for two hours. In combat, two Hurricanes were shot down by the Dornier's return fire. Low-level attacks were abandoned after The Hardest Day. I./KG 76 was reduced to 19 out of 29 serviceable machines by 18 August 1940 but II. Gruppe numbers are unknown for this period. III. Gruppe reported 17 from 24 Do 17s ready for action on 24 August. 76 were in action on 23 August and reported one loss. On 24 August III./KG 76 attacked RAF North Weald and RAF Hornchurch while II./KG 76 bombed Biggin Hill. The Stab unit lost two Dorniers in action with No. 264 Squadron RAF and 4 staffel lost two and one damaged in combat with the same RAF squadron. KG 76 are known to have been in action on 25 August, for 3 staffel lost a bomber in combat with No. 32 Squadron RAF. II./KG 76 returned to Biggin Hill on 31 August. The group apparently flew with a formation of Heinkel He 111s from an unknown unit. A mixed force of Dorniers and Heinkels bombed both Biggin Hill and RAF Croydon. The He 111s appear to have bombed Biggin Hill, destroying two of the three remaining hangars, the living quarters and operations room eliminating the telephone system. II. Gruppe lost one Do 17 in combat with No. 151 Squadron RAF over the Thames Estuary. Elements of KG 76 bombed Kenley on 6 September. 6. Staffel reported the only losses of the wing this day. Three Ju 88s crashed, one being badly damaged in combat with No. 41 Squadron RAF fighter ace Eric Lock. Two more were posted missing after being engaged by 111 Squadron and anti-aircraft artillery. KG 76 probably took part in the attack on London the following day which began The Blitz and marked a change in German strategy from attacking RAF airfields to bombing cities. No loss appears to have been reported on 7 September by KG 76 although 63 German aircraft suffered destruction or damage on 7 September. On 15 September 1940 KG 76 were part of an all-out attack on London that became known in the historiography of the Battle of Britain as the "Battle of Britain Day". The wing spearheaded the first major raid of the day. Major Alois Lindmayr Gruppenkommandeur of I./KG 76, led the entire formation.
