Owing to the rapidity of the French flight and the Russian pursuit and the consequent exhaustion of the horses, the chief means of approximately ascertaining the enemy’s position⁠—by cavalry scouting⁠—was not available. Besides, as a result of the frequent and rapid change of position by each army, even what information was obtained could not be delivered in time. If news was received one day that the enemy had been in a certain position the day before, by the third day when something could have been done, that army was already two days’ march farther on and in quite another position.

One army fled and the other pursued. Beyond Smolénsk there were several different roads available for the French, and one would have thought that during their stay of four days they might have learned where the enemy was, might have arranged some more advantageous plan and undertaken something new. But after a four days’ halt the mob, with no maneuvers or plans, again began running along the beaten track, neither to the right nor to the left but along the old⁠—the worst⁠—road, through Krásnoe and Orshá.
