Then came the battalion problems, the proper use of grenades by men advancing in formations against a mythical enemy in intrenched positions.

From the beginning, the American Army refused to accept the theory that the war would never again get into the open. They trained in open warfare, and with a far greater zest—partly, of course, because it was the thing they knew already, though they found they had some things to unlearn.

Then the war brought about a reorganization of American army units, and it was necessary for the officers to familiarize themselves with new conditions. The reorganization was ordered early in August, and put into effect shortly afterward. The request from General Pershing that the administrative units of the infantry be altered to conform with European systems had in its favor the fact that it economized higher officers and regimental staffs, for at the same time that divisions were made smaller, regiments were made larger.

The new arrangement of the infantry called for a company of 250 enlisted men and 6 commissioned officers, instead of 100 men and 3 officers. Each company was then divided into 4 platoons, with a lieutenant in command. Each regiment was made up of 3 battalions of 4 companies each, supplemented by regimental headquarters and the supply and machine-gun organizations.

This made it possible to have 1 colonel and 3 battalion commanders officer 3,600 men, as against 2,000 of the old order.

This army in the making was not called on to show itself in the mass till August 16, just a month after its hard work had begun. Then Major-General Sibert, field-commander of the First Division and best-loved man in France, held a review of all the troops. The manœuvres were held in a great open plain. The marching was done to spirited bands, who had to offset a driving rain-storm to keep the men perked up. The physical exercise of the first month showed in the carriage of the men, infinitely improved, and they marched admirably, in spite of the fact that their first training had been a specialization in technical trench warfare. General Sibert made them a short address of undiluted praise, and they went back to work again.

A few days later the army had its first intelligence drill, with the result that some erstwhile soldiers were told off to cook and tend mules.

The test consisted in delivering oral messages. One message was: "Major Blank sends his compliments to Captain Nameless, and orders him to move L Company one-half mile to the east, and support K Company in the attack." The officer who gave the message then moved up the hill and prepared to receive it.

The third man up came in panting excitement, full of earnest desire to do well. "Captain, the major says that you're to move your men a mile to the east," he said, "and attack K Company." He peeled the potatoes for supper.

The gas tests came late in August. The officers, believing that fear of gas could not be excessive, had done some tall talking before the masks were given out, and in the first test, when the men were to enter a gas-filled chamber with their masks on, they had all been assured that one whiff would be fatal. The gas in the chamber was of the tear-compelling kind, only temporarily harmful, even on exposure to it. But that was a secret.
