Here at Gièvres other trains were made up to continue the journey forward in answer to the daily requisitions of the regulating stations upon the intermediate reserves. War being a one-way business, all expenditure and no income, all loaded cars were going one way except those bringing lumber and ties that we were cutting from the forests for construction, salvage from the battlefield, broken trucks, and vehicles--and the hospital trains. Here prevision must be most sure. Man was the most valuable piece of machinery; his repair the most important of all repairs. We had enormous hospitals in the intermediate zone as well as at the base ports; and indeed all over central and southern France. The medical corps used great hotels and other buildings to care for the hosts of broken, gassed, exhausted, sick men from the Meuse-Argonne battle; but when we had to build we ran out spur tracks--deep was our faith in spur tracks--into open fields upon which rose cities of standardized unit hospital buildings, all of a color, all of a pattern, and also operating rooms and Y. M. C. A. clubs and theaters, under the autocracy of some regular surgeon who looked up from his desk at the chart on the wall showing the number of his patients and the number of vacant beds. The hospital trains ran up on the spur tracks, and hobbling wounded descended, and wounded who could not hobble were carried on stretchers to their beds--each a card-indexed automaton, no less than when he entered the training camp, as he would remain until he was demobilized or buried in France.
