Just as the West Point system, which takes the "plebes" in hand, was being applied in our training camps, so Leavenworth staff college was reproduced in France in the ancient city of Langres, near Chaumont, which had been a fortress in many wars. Here regulars worked beside reserves, while the regulars had no special privileges except the first choice of horses to ride. Here they were to learn how to solve the tactical management of troops in action, the technique of all the different G's of the staff: G-1 and G-4, which had to do with transport and supply; G-2, which had to do with intelligence; G-3, with operations, and G-5, with training. There was much to teach in that three months' course. How long will it take to reach all the units of a division, billeted in ten villages in an area of ten square miles, with an order for movement? How will it be sent? How will it be written after consultation with G-1, who knows the transport available? Which units will march out first? How long will it take to entrain those going by train? If the motor transport, and the horse-drawn transport, too, have to go overland, what roads will they take to reach their destination? Have the drivers their maps? In making a relief in the trenches, how long will it take to march up and complete the task? Four German prisoners say one thing, four another, and three another. Take their reports in connection with aeroplane reports and general observation. What is your decision as to the enemy's strength on your front? Two additional divisions are suddenly brought into your sector. How are you to feed them? An attack is planned to pinch out a salient. How long is to be your artillery preparation? What its character? What points will you cover with the corps artillery fire? What with the divisional howitzers? There is your map with the information in G-2's possession for G-3 to consider in working out details. The infantry must be preceded by a barrage worked out with a mathematical accuracy, that will be practicable for the gunners and the infantry. All the fundamentals of technical knowledge were what arithmetic, algebra and geometry, and the strength of materials are to a bridge builder, in solving the problems presented to civilians, lawyers, engineers, and scholars of ages from twenty-five to forty-five, who worked them out and went to recitation in a school-room where they sat at little desks, as they did in boyhood days.
