Every man, every platoon, and on through the different units to divisions and corps, was moving on a time schedule. A competition between companies to "get there" first would have resulted from the start in a hopeless tangle. If not literally, it may be said broadly that each company was to be at a given point on the map at a given hour; and if one company, or battalion or regiment, for that matter, outdistanced another, it was because it had kept its schedule and the other had not. In case it became "heady" and was on its objective in advance of schedule, it ran the risk of "exposing its flanks." At least that is the theory of the staff in its essence. An ideal army, according to the staff, would be at a given line on the map at 10.30, at another at 11.30, and so on. This might be possible if there were no enemy to consider, although it would require an adept army, as everyone who has ever drilled recruits well appreciates. He knows how long it takes to train them, and to learn how to direct a small force in carrying out satisfactorily a practice skirmish evolution over slightly uneven ground. The gregarious instinct of itself seems to break uniformity by drawing men into groups in face of infantry fire in battle for the first time, as well as eagerness to close with the enemy and gravitation away from the points of its concentration. Shell-bursts scatter them, casualties make gaps which lead to further disorganization. Could our army have had reproduced for its edification the confusion of the battle of Bull Run or of Shiloh, it would have realized the purpose of all the painstaking drill, the monotonous and wearing discipline, which made the well-ordered movement possible. Its very deliberateness in maintaining the coördination of all its units gave it a majesty in its broad and mighty sweep, which was more like the sweep of a great river than the cataract rush of the small forces of the old days, which the public still continued to visualize as a charge. I thought of it too as in keeping with the organization of modern life, in the trains entering and leaving a great city station or the methodical processes of a vast manufacturing concern. How did our men know whether or not they were keeping their schedule? Did they look at their watches as they counted their steps? They had a monitor at first in the rolling barrage, that curtain of fire which preceded them. This was their moving shield which the guns far in rear provided for their guidance as well as protection. If they came too close to the barrage, they were exposed no less than their enemies to death from its hail.
