 The long eastern flank of 2 panzer group was a problem, and Generaloberst Guderian shifted the 112th division as part of the LIII corps to his right to shore up the protection there

The division, redeploying to the region south of Tula, met forces from the Soviet 13th Army near Teploye, who were attempting to drive on Tula from the east and disrupt the German armoured thrust towards Moscow.The Soviets using the superior mobility of their cavalry units, delayed the LIII corps mission so much that Guderian had to reinforce it with tanks, artillery and flak, a move which slowed the whole advance of the Panzer Grupe.With the aid of the reinforcements, the 112th infantry division drove the 13th Army forces off to the east and advanced towards Stalinogorsk.
