In the aftermath of the encirclement of the 6th Army on 23 November 1942, the "Geschwaderstab" was moved to Morozovskaya-West, outside the Stalingrad pocket. Wilcke organized fighter escort missions for the transport aircraft delivering supplies for the 6th Army. Pressed by the advancing Soviet armored spearheads, Morozovskaya-West had to be abandoned by the "Geschwaderstab" on 23 December, and the aircraft were moved to Morozovskaya-South, which was not yet threatened by the Soviet Army. On 3 January 1943, this airfield had to be abandoned as well and the "Geschwaderstab" was relocated to Tazinskaya, there it remained until the fighting over the Stalingrad pocket ended. During this period the "Geschwaderstab" claimed 25 victories, 21 by Wilcke and 4 by Dahl, for the loss in action of two pilots.
