While being the "Geschwaderkommodore" of JG 1 Oesau frequently received his share of Hermann Göring's anger and frustration over the failure to beat off the Allied bomber offensive. Göring questioned the commitment of commanders who were not flying regularly and thus not really "leading" their respective units. In this context it should be stated that in order not to risk one of the Luftwaffe "expert"'s life fighter aces were called "Experten", there was an automatic ban on Oesau for further combat flying since his 100th victory. Perhaps the ban was lifted temporarily or bypassed when he was appointed "Geschwaderkommodore" of JG 1. On the other hand, Oesau might simply have ignored the ban and continued to lead missions.
