We left Toul at 1 o'clock and marched toward the front. We were soon within the sound of the heavy guns. We continued on the road for several hours, and then, as we were getting into the zone where shells fell occasionally, we were told to thin out our ranks so that if a shell fell among us our casualties would be light. From then on, we marched about eight or ten feet apart in single file on each side of the road. We were ordered to wear our steel helmets as a protection against shrapnel. Some did not see the need of doing this, but most of us were glad to take the precaution. We crossed several narrow gauge tracks on our march, and saw trains carrying supplies of all kinds to the battle front. They were pulled by gasoline engines. We also saw our first barbed wire entanglements. These were built back of the lines as a protection to the French in case the Germans should break through on that front. They were about twenty-five feet in width and extended north and south as far as the eye could see. Later on we saw barbed wire entanglements as much as 250 feet in width, put up as a barrier to the Boche, should they break through. Airplanes were now very numerous. They were darting back and forth at various heights. We were anxious to see an airplane battle, but none took place on that front on that day. We could see observation balloons in the distance. Those in the very far distance we knew to be enemy observers. We marched until 7 o'clock, when we reached a woods, where we were permitted to stop. We were given our evening meal, which consisted of bully beef and hard tack. The woods was our sheltering place for the night. Some of the boys said they slept well that night, but I will be absolutely truthful and say that I did not. The knowledge that we were under shell fire and the unforeseen events that the immediate future held in store for me so weighed upon my mind that I could scarcely close my eyes. I really do not understand how any of the boys slept. We could hear the screech of the shells as they whizzed by, but, fortunately, none of them hit near us. Only a few days before several hundred American boys were gassed in this same woods, and our gas guard kept a close watch for gas shells.
