Having been subjected to intensive operations over the Amiens battle in August 1918, by mid-September an exhausted JG I was withdrawn from the British part of the front, having lost all four Jasta commanders by the end of August; Lowenhardt of Jasta 10 was killed, Jasta 6's Co Lt. Paul Wenzel and Lothar von Richthofen of Jasta 11 both wounded and hospitalised, and Lt. Ernst Udet (Jasta 4) exhausted and sent on leave. JG I scored just 17 claims during September, despite the month seeing the highest losses for the Allied Air Forces of the war (The Jasta force claiming some 721 victories for the month). For the next three months the likes of Leutnant Friedrich Noltenius in Jasta 11, Jasta 6's Commanding Officer Ulrich Neckel, and Leutnant Arthur Laumann (Jasta 10) did the majority of the scoring.
