After the encounter at Vyázma, where Kutúzov had been unable to hold back his troops in their anxiety to overwhelm and cut off the enemy and so on, the farther movement of the fleeing French, and of the Russians who pursued them, continued as far as Krásnoe without a battle. The flight was so rapid that the Russian army pursuing the French could not keep up with them; cavalry and artillery horses broke down, and the information received of the movements of the French was never reliable.

The men in the Russian army were so worn out by this continuous marching at the rate of twenty-seven miles a day that they could not go any faster.

To realize the degree of exhaustion of the Russian army it is only necessary to grasp clearly the meaning of the fact that, while not losing more than five thousand killed and wounded after Tarútino and less than a hundred prisoners, the Russian army which left that place a hundred thousand strong reached Krásnoe with only fifty thousand.
