The concentrated activity which had begun at the Emperor's headquarters in the morning and had started the whole movement that followed was like the first movement of the main wheel of a large tower clock.

One wheel slowly moved, another was set in motion, and a third, and wheels began to revolve faster and faster, levers and cogwheels to work, chimes to play, figures to pop out, and the hands to advance with regular motion as a result of all that activity.

Just as in the mechanism of a clock, so in the mechanism of the military machine, an impulse once given leads to the final result; and just as indifferently quiescent till the moment when motion is transmitted to them are the parts of the mechanism which the impulse has not yet reached.
