At the Battle of Maloyaroslavets the French tried to reach Kaluga, where they could find food and forage supplies. The replenished Russian Army blocked the road, and Napoleon was forced to retreat the same way he had come to Moscow, through the heavily ravaged areas along the Smolensk road. In the following weeks, the "Grande Armée" was dealt a catastrophic blow by the onset of the Russian Winter, the lack of supplies and constant guerrilla warfare by Russian peasants and irregular troops.
