It was just as great a mistake to preach about sacrifice after a battle. In battle sacrifice was the most common thing; ordinary men rose to heights of heroism to save their "buddies" or to assist in the advance. The high courage of self-sacrifice became familiar. Preaching self-sacrifice to these men was useless--for Christian as well as Jew. They had seen stretcher bearers shot down while carrying their precious burdens to the rear. They had seen officers killed while getting their men under shelter. They had seen the gas guard, as a part of his daily duty, risk the most horrible of deaths in order to give the alarm for his comrades. Such men responded to an appeal on the divine in man, on the brotherhood of all those heroes about them, on Americanism, on a hundred congenial themes; they did not see the cogency of an appeal to sacrifice. The profound friendships and violent dislikes of the soldier have been often noticed. His fidelity to his "buddy," to any popular officer, to his company and regiment, stand out as part of his vigorous, boyish outlook. On the other hand, a swiftly acquired prejudice would go with him forever in the face of many facts and much argument to the contrary. The relative standing of the Y. M. C. A. and the Salvation Army among the men is a case in point. The Young Men's Christian Association was by far the largest war work organization which worked among the mass of the soldiers, as the Red Cross confined its activities largely to hospitals and related fields. It was a wide-spread organization, covering practically every unit and almost every type of activity, religious, athletic, entertainment, canteen. But the soldier, while using the Y. M. C. A., disliked it. The Salvation Army, a very small organization in both amount and scope of work, which I never saw in action because I did not happen to be in the limited sector it covered, was, however, popular if only by hearsay in every part of the great army. Now, the soldier had very real grievances against the "Y." It charged him more for its tobacco than did the quartermaster's store; it gave away very little, while other organizations, not burdened with the canteen, gave away a great deal; it had a certain proportion of misfits, men who did not belong in any military work, who considered themselves better than the common soldier and did not share his trials or his viewpoint.
