The people had a single aim: to free their land from invasion. That aim was attained in the first place of itself, as the French ran away, and so it was only necessary not to stop their flight. Secondly it was attained by the guerrilla warfare which was destroying the French, and thirdly by the fact that a large Russian army was following the French, ready to use its strength in case their movement stopped.
The Russian army had to act like a whip to a running animal. And the experienced driver knew it was better to hold the whip raised as a menace than to strike the running animal on the head.
