All armies are looking either back at the last war or ahead to the next. One element, leaning back on its oars, considers the lessons of the last war, if it were won, as setting all precedents for present policy. Another, usually the men who were not in the last war except as captains and lieutenants, considers that new conditions will again set new precedents in the next war. The officers in the forties in the days of the war with Spain and the Philippine rebellion, who chafed at the Civil War traditions of their seniors, now had command of divisions, while in the Great War the Leavenworth men who were in the thirties and forties were pushing up from below. If the later generation lacked rank on this occasion, it had power in France as the result of Leavenworth and the new staff system, while promotion by selection called its ambition. Leavenworth graduates sat in the seats of the mighty on the right and left hand of the Commander-in-Chief; the tables of organization were of their devising; the orders signed by the Chief of Staff, which the divisional and the corps generals and all the generals of the Services of Supply had to obey, originated from this inner circle in the barracks buildings at Chaumont, which was surrounded with professional mystery. Divisional and corps chiefs of staff were Leavenworth men in touch with the inner circle. The disrespectful thought of these officers as the Leavenworth "clique"; but it was not the fashion to do much thinking aloud about them, such was their power. They did not think of themselves as a clique; not even the members of a secret society think of themselves in that way. They were a group of veterans, who if they had not the scars won in battle--we had had no great battles since the Civil War--had burned the midnight oil and played the war game together. They had, as volunteers, in order to learn their profession, when the people of the country knew no more of their existence than if they had been in a monastery, gone through a post-graduate course as rigorous as West Point itself. They thought of themselves as apostles, their voices unheard in a land saturated with pacifism and indifference, who, in fasting, prayer, and industry, had studied the true gospel in their holy of holies. They alone had conned the pages of the sacred books behind the altar where the regular army kept the sacred fires burning. "War is the greatest game on earth," as one of them said. In this thought they had the same reason for enthusiasm in study as a chemist in his experiments or an architect in his building. In their school in the wheat fields of Kansas they were manipulating in theory forces which made a hundred million dollar corporation an incidental pawn. But they were dealing with the imaginary, and the managers of the corporation with the real. When the war came all their forces of imagination became real.
