The Germans retreated from the suburbs of Stalingrad to the city itself. The loss of the two airfields, at Pitomnik on 16 January 1943 and Gumrak on the night of 21/22 January, meant an end to air supplies and to the flying out the wounded. The third and last runway was at the Stalingradskaja flight school, which had the last landings and takeoffs on the night of 22–23 January. After that, there were no landings except for air drops of ammunition and food.
