The forces of a dozen European nations burst into Russia. The Russian army and people avoided a collision till Smolénsk was reached, and again from Smolénsk to Borodinó. The French army pushed on to Moscow, its goal, its impetus ever increasing as it neared its aim, just as the velocity of a falling body increases as it approaches the earth. Behind it were seven hundred miles of hunger-stricken, hostile country; ahead were a few dozen miles separating it from its goal. Every soldier in Napoleon’s army felt this and the invasion moved on by its own momentum.
The more the Russian army retreated the more fiercely a spirit of hatred of the enemy flared up, and while it retreated the army increased and consolidated. At Borodinó a collision took place. Neither army was broken up, but the Russian army retreated immediately after the collision as inevitably as a ball recoils after colliding with another having a greater momentum, and with equal inevitability the ball of invasion that had advanced with such momentum rolled on for some distance, though the collision had deprived it of all its force.
