With the loss of Arnold Lignitz on 30 September (shot down over Leningrad), Hauptmann Seiler was assigned to command III. Gruppe (also based at Siverskaya), as Barbarossa entered its critical phase. Despite surrounding the city, it could not be taken so Hitler decided instead to besiege it. For the next three years, JG 54 would stay, essentially, encamped outside the city interdicting the supply lines and intercepting the frantic attempts of the Russians to lift the siege in offensive after offensive.
