 The Soviets continued to pour aerial reinforcements into the Stalingrad area in late September, but continued to suffer appalling losses; the "Luftwaffe" had complete control of the skies.The burden of the initial defence of the city fell on the 1077th Anti-Aircraft Regiment, a unit made up mainly of young female volunteers who had no training for engaging ground targets.Despite this, and with no support available from other units, the AA gunners stayed at their posts and took on the advancing panzers.
