The geography of the Verdun country unrolled before us with absolute clarity; the whole relation of hills and river and railroads was unmistakable. But despite the faint sound of musketry, the occasional roar of a French gun, I might have been in the Berkshires looking down on the Housatonic. Six miles to the north around Le Mort Homme that battle which has not stopped for two months was still going on. Around Douaumont the overture was just starting, the overture to a stiff fight in the afternoon, but of all the circumstances of battle that one has read of, that one still vaguely expects to see, there was not a sign. If it suited their fancy the Germans could turn the hill on which I stood into a crater of ruin, as they did with Fort Loncin at Liège. We were well within range, easy range; we lived because they had no object to serve by such shooting, but we were without even a hint of their whereabouts. I have already described the military geography of Verdun. I shall not attempt to repeat it here, but it is the invisibility of warfare, whether examined from the earth or the air, which impresses the civilian. If you go to the trenches you creep through tunnels and cavities until you are permitted to peer through a peephole, and you see yellow dirt some yards away. You may hear bullets over your head, you may hear shells passing, but what you see is a hillside with some slashings. That is the enemy. If you go to an observation post back of the trenches, then you will see a whole range of country, but not even the trenches of your own side. From the Grand Mont east of Nancy I watched some French batteries shell the German line. I didn't see the French guns, I didn't see the German trenches, I didn't see the French line. I did see some black smoke rising a little above the underbrush, and I was told that the shells were striking behind the German lines and that the gunners were searching for a German battery. But I might as well have been observing a gang of Italians at blasting operations in the Montclair Mountains. And the officer with me said: "Our children are just amusing themselves." From Fort de la Chaume we rode back to the citadel; and there I was the guest of the General and the officers of the town garrison; their guest because I was an American who came to see their town. I shall always remember that luncheon down in the very depths of this rock in a dimly lighted room. I sat at the General's right, and all around me were the men whose day's work it was to keep the roads open, the machinery running in the shell-cursed city. Every time they went out into daylight they knew that they might not return. For two months the storm had beaten about this rock, it had written its mark upon all these faces, and yet it had neither extinguished the light nor the laughter; the sense of strength and of calmness was inescapable, and never have I known such charming, such thoughtful hosts.
