Within the combat units, the vacancies were to be filled two-thirds by men in line of promotion within the unit itself, and one-third from the replacement divisions.

The replacement division's higher officers were those recovered from wounds, who had lost their place in line, and those who had not yet had any assignments. To keep up a sufficient number of replacement divisions, the arriving depot battalions were held to belong with them.

This school was located near the fighting-line, and its instructors were preponderantly American.

It put the "stars of the general into the private's knapsack," and began the great mill of officer-making that the experiences of other armies had shown to be so tragically necessary. Needless to say, it was packed to overflowing from its first day.

CHAPTER XI
SOME DISTINGUISHED VISITORS

SO satisfactory to itself was the progress of the American Expeditionary Force in becoming an army that by the end of its first month of training it was ready for important visitors. True, the first to come was one who would be certain to understand the force's initial difficulties, and who would also be able to help as well as inspect. He was General Petain, Commander-in-Chief of the French Army, and he came for inspection of both French and American troops on August 19, three days after General Sibert had had a family field-day to take account of his troops.

General Petain came down with General Pershing, and the first inspection was of billets. Then the two generals reviewed the Alpine Chasseurs, and General Petain awarded some medals which had been due since the month before, when the Blue Devils were in the line.

After General Petain's visit with the American troops, he recommended their training and their physique equally, and said: "I think the American Army will be an admirable fighting force within a short time."

This was also General Pershing's day for learning—his first session with one of his most difficult tasks. He had to follow the example of General Petain, and kiss the children, and accept the bouquets thrust upon both generals by all the little girls of the near-by Vosges towns.

General Pershing did better with the kissing as his day wore on, though its foreignness to his experience was plain to the end. But with the bouquets he was an outright failure. Graciously as he might accept them, the holding of them was much as a doughboy might hold his first armful of live grenades.
