Involuntarily I searched the faces of these men as they passed. They were hardly ten feet from me. Platoon after platoon, company after company, whole regiments in columns of fours. And seeing the faces brought an instant shock; they all wore the same calm, steady, slightly weary expression, but there was in the whole line scarcely a young man. Here were men of the thirties, not the twenties; men still in the prime of strength, of health, but the fathers of families, the men of full manhood. Almost in a flash the fact came home. This was what all the graves along the road had meant. This was what the battlefields and the glories of the twenty months had spelled--France had sent her youth and it was spent; she was sending her manhood now. In the line no man smiled and no man straggled; the ranks were closed up and there were neither commands nor any visible sign of authority. These men who were marching to the sound of the guns had been there before. They knew precisely what it meant. Yet you could not but feel that as they went a little wearily, sadly, they marched willingly. They would not have it otherwise. Their faces were the faces of men who had taken the full measure of their own fate. You had a sense of the loathing, the horror, above all the sadness that was in their hearts that this thing, this war, this destruction had to be. They had come back here through all the waste of ruined villages and shell-torn hillsides; all the men that you saw would not measure the cost of a single hour of trench fighting if the real attack began. This these men knew, and the message of the artillery fire, which was only one of unknown terrors for you, was intelligible to the utmost to each of them. And yet with the weariness there was a certain resignation, a certain patience, a certain sense of comprehending sacrifice that more than all else is France to-day, the true France. This, and not the empty forts, not even the busy guns, was the wall that defended France, this line of men. If it broke there would come thundering down again out of the north all the tornado of destruction that had turned Northeastern France into a waste place and wrecked so much of the world's store of the beautiful and the inspiring. Somehow you felt that this was in the minds of all these men. They had willed to die that France might live. They were going to a death that sounded ever more clearly as they marched. This death had eaten up all that was young, most of what was young at the least, of France; it might yet consume France, and so these men marched to the sound of the guns, not to martial music, not with any suggestion of dash, of enthusiasm, but quietly, steadily, all with the same look upon their faces--the look of men who have seen death and are to see it again. Instinctively I thought of what Kipling had said to me in London:
