This was where the general wanted the body of men and equipment to be, and here they were. There were no dragging ends in the rear, so far as I could see; nobody complaining that food or ammunition was not up; no aide looking for somebody who could not be found; no excited staff officer rushing about shouting for somebody to look sharp for somebody had made a mistake. The thing was unwarlike; it was like a particularly well-thought-out route march. Yet at the word that company of cavalry might be in the thick of it, at the point where they were wanted; the infantry rushing to the support of the firing-line; the motor transport facing around for withdrawal, if need be. It was only a little way, indeed, into the zone of death from the rear of that compact column.
Thousands of such compact bodies on as many roads, each seemingly a force by itself and each a part of the whole, which could be a dependable whole only when every part was ready, alert, and up where it belonged! Nothing can be left to chance in a battle-line three hundred miles long. The general must know what to depend on, mile by mile, in his plans. Millions of human units are grouped in increasingly larger units, harmonised according to set forms. The most complex of all machines is that of a vast army, which yet must be kept most simple. No unit acts without regard to the others; every one must know how to do his part. The parts of the machine are standardised. One is like the other in training, uniform, and every detail, so that one can replace another. Oldest of all trades this of war; old experts the French. What one saw was like manœuvres. It must be like manœuvres or the army would not hold together. Manœuvres are to teach armies coherence; war tries out that coherence, which you may not have if some one does not know just what to do; if he is uncertain in his rôle. Haste leads to confusion; haste is only for supreme moments. In order to know how to hasten when the hurry call comes, the mighty organism must move in its routine with the smoothness of a well-rehearsed play.
Joffre and the others who directed the machine must know more than the mechanics of staff-control. They must know the character of the man-material in the machine. It was their duty as real Frenchmen to understand Frenchmen, their verve, their restlessness for the offensive, their individualism, their democratic intelligence, the value of their elation, the drawback of their tendency to depression and to think for themselves. Indeed, the leader must counteract the faults of his people and make the most of their virtues.
