It is interesting to note two interesting events in his career. The first is his removal of command of KG 77. No doubt he was relieved of his duty due to some reason, as it happened in the middle of the Polish Campaign, and he spend the following month pending an assignment. According to Spick, this was due to his refusal of attacks on civilian targets, but I have also seen suggestions it was due to his incompetent command. The second is when he was retired, and then recalled back to the service in 1945. Rather weird, is not it?
