In no result was the fact more evident than in our traffic direction that in making a large army we must crack the mold of a small army. In time our capacity for organization would make a new mold. Meanwhile, though it might be applied at cross-purposes, our American energy, adaptable, tireless, furious, and determined, must bring results. The many broken-down trucks in ditches beside the road were only the inevitable casualties of a prodigious effort. Let the infantrymen keep on advancing; we would force their supplies up to them in one way or another. VIII THE FIRST DAY Out in the open--The enemy limited to passive defense--And relying on machine-gunners--Their elusiveness--Problems of the offense--Slowing down--Up with the infantry--Why dispersion--_Liaison_ up, down, and across--How keep the staff informed?--The spent wave before Montfaucon. What of the infantry lost to view in the folds of the landscape? They were confronting the originals of the hills, woods, and ravines, whose contours on paper had been the definite factor in making plans, while the character and resistance of the enemy had been the indefinite and ungovernable quantity. As the day advanced, irregular pencilings, reflecting the reports of the progress of the fighters, moved forward on the maps of the different headquarters toward the heavy regular lines of the objectives which were the goals of our high ambition. The loss of the first-line fortifications to the Germans could not be considered as serious as in an offensive in the first years of the war. Even as early as the Verdun battle, proponents of the mobile school of warfare, who had never been altogether silenced by the engineering school, had advocated a yielding elastic defense, which, after drawing the Crown Prince's Armies away from their depots, would counter by a sudden attack of the gathered French forces; but such a maneuver was too daring and contrary to the thought of the time, with its dependence upon rigid defense. Infantry had fallen into the habit of feeling "undressed" and helpless unless in trenches. When the soldier was forced into the open, he had hastened to hide his "nakedness" in a shell-crater, or instantly, in the very rodent instinct that he had developed, set to digging himself a pit. Since the German offensive of March, 1918, all the practice had been to wean the infantry away from settled defenses to the supple use of light artillery, trench mortars, and machine-gun units. Happily, as we know, the basic training of our infantry had been in keeping with this idea.
