A "pill-box" is a tiny concrete fortress, set up in front of the trenches, usually in groups of fifteen to twenty. They have slot-like apertures, through which Germans do their sniping. They are supposed to be immune from anything except direct hit by a huge shell. But the American artillery camp worked out a way of getting them—with luck. Each aperture, through which the German inmates sighted and shot, was put under fire from automatic rifles, coming from several directions at once, so that it was indiscreet for the Boche to stay near his windows, on any slant he could devise. Under cover of this rifle barrage, bombers crept forward, and at a signal the rifle fire stopped, and the bombers threw their destruction in.

All these accomplishments, which did not take overlong to learn, enhanced the natural value of the American artilleryman. He became, in a short time, the pride of the army and a warmly welcomed mainstay to the Allies.

Major-General Peyton C. March, who took the artillery to France and commanded them in their days of organization, before he was called back to be Chief of Staff at Washington, was always credited, by his men, with being three-fourths of the reason why they made such a showing. General March always credited the matter to his men. At any rate, between them they put their country's best foot foremost for the first year of America in France, and they served as optimism centres even when distress over other delays threatened the stoutest hearts.

CHAPTER IX
THE EYES OF THE ARMY

AMERICA'S beginnings in the air service were pretty closely kin to her other beginnings—she furnished the men and took over the apparatus. And although by September 1, 1917, she had large numbers of aviators in the making in France, they were flying—or aspiring to—in French schools, under American supervision, with French machines and French instructors.

There existed, in prospect, and already in detailed design, several enormous flying-fields, to be built and equipped by America, as well as half a dozen big repair-shops, and one gigantic combination repair-shop, assembling-shop, and manufacturing plant.

But in the autumn, when there were aviators waiting in France to go up that very day, there was no waiting on fields trimmed by America.

When the main school, under American supervision, had filled to overflowing, the remaining probationers were scattered among the French schools under French supervision. Meanwhile, the engineers and stevedores shared the work of constructing "the largest aviation-field in the world" in central France.

It was once true of complete armies that they could be trained to warfare in their own home fields, and then sent to whatever part of the world happened to be in dispute, and they required no more additional furbishing up than a short rest from the journey. That is no longer true of anything about an army except the air service, and it isn't literally true of them. But they approach it.

So it was practicable to give the American aviators nine-tenths of their training at home, and leave the merest frills to a few spare days in France. This, of course, takes no account of the first weeks at the battle-front, which are only nominally training, since in the course of them a flier may well have to battle for his life, and often does catch a German, if he chances on one as untutored as himself.
