Although the 6th Army had managed to capture most of the city and had pushed the Soviets to the banks of the Volga river in several places, it needed several more infantry divisions (as explained above), to take the city completely. In spite of repeated requests to the German high command, the 6th Army was not reinforced because no other reinforcements were available in the region, or close enough to support them. As the battle grew more intense, the Soviets counterattacked on both sides of the 6th Army's flanks and destroyed the Romanian 3rd and 4th Armies. The Soviet pincers then linked up, thereby surrounding and ultimately destroying the 6th Army.
