While the Stalingrad Front launched its offensive on 20 November, the 65th Soviet Army continued to apply pressure to the German 11th Corps along the northern shoulder of the Sixth Army's flank. The Red Army's 4th Tank Corps advanced beyond the German 11th Corps, while the 3rd Guards Cavalry Corps crashed into the German unit's rear. The German 376th Infantry Division and the Austrian 44th Infantry Division began to redeploy to face the enemy on their flanks, but were hindered by shortage of fuel. The 14th Panzer Division's panzer regiment destroyed a flanking regiment of the Soviet 3rd Guards Cavalry Corps, but its anti-tank artillery suffered heavy casualties when it was overrun by Soviet forces. By the end of the day the Soviet 1st Tank Corps was chasing the retreating 48th Panzer Corps, while the Soviet 26th Tank Corps had captured the town of Perelazovsky, almost to the northwest of Stalingrad.
