To the military man the subject is extremely simple. There is no mystery about it. The chaplain is in the army as the physician is, as the thousands of other non-combatants are, for a strictly military purpose. It happens that the non-combatants may use non-military methods. One may drive a locomotive, another carry a stretcher, another sit in an office and make out papers. All are essential to the military machine; none is in the service for any special humanitarian purpose; none is present as a survival of mediaevalism, but all to take part in the grim conflict of the twentieth century. The work of a physician in the military service is the very utilitarian one of saving men's lives and returning them to the front. The work of a chaplain is the equally essential and practical one of stimulating the morale of the troops. Many factors bear upon the morale of a body of men,--their physical environment, the strength and spirit of their individual units, the temper and ability of their leaders. In our army we were very fortunate in the activity of various civilian organizations which labored among the men in the service with the backing of our entire citizenry, or at least of large and influential groups. The home service of the Red Cross and other non-military organizations was of great importance in keeping up the morale of the families left behind and through them of the men overseas. These important organizations, however, were under the handicap of doing civilian work among soldiers--a handicap whose seriousness only a soldier himself can ever realize. Some months after the war was over, the army recognized its obligation by appointing morale officers for both larger and smaller units, with others under them to supervise athletics, entertainment, and the like. The civilian organizations then conducted their activities under the orders of the morale officer. But nearest of all to the men, because themselves a part of the actual military machine, were their own chaplains. The chaplain was under the same orders as the men, took the same risk, wore the same uniform, and naturally was regarded in every way as one of their own. I have even heard old army men scorning the new advances of all these new war-time societies. "We have our own chaplain," they said, "He looks after us all right."
