He was then grounded from flying on operations, as his experience and leadership qualities were regarded as too valuable to risk further in front line combat. He did fly on occasional sorties, the most famous involving the shooting down of an Avro Lancaster bomber of No. 44 Squadron RAF piloted by Warrant Officer G. T. Rhodes in April 1942, during a rare RAF daylight raid on the MAN engine plant in Augsburg. It was his 101st kill. In August 1942, the "Geschwaderstab" of JG 2 exchanged their Bf 109 F aircraft for Fw 190 A–2s.
