Toward nightfall of one of these days of desperate fighting it was discovered that the ammunition supply of the first battalion of the 110th was running low, and Corporal Harold F. Wickerham, Washington, Pa., and Private Boynton David Marchand, Monongahela City, Pa., were sent back with a message for brigade headquarters. When they reached the spot where the headquarters had been they found it had been moved. They walked for miles through the woods in the darkness and finally came to a town where another regiment was stationed, and they sent their message over the military telephone. They were invited to remain the rest of the night and sleep; fearing the message might not get through properly, however, and knowing the grave need of more ammunition, they set out again, and toward morning reached their own ammunition dump and confirmed the message orally. Again they refused a chance to rest, and set out to rejoin their command, which they reached just in time to take part in a battle in the afternoon. Such are the characteristics of the American soldier. Somewhat the same fate as befell Epieds, which had been completely leveled by artillery fire, came to the village of Le Charmel. After violent fighting lasting two hours, during which the village changed hands twice, it was blown to pieces by the artillery, and our men took possession, driving the Germans on northeastward. The Pennsylvanians now began to feel the change in the German resistance as the Boche retreat reached its second line of defense, based on the Ourcq River, and the fighting became hourly more bitter and determined. This, as well as the dense forests, where the Germans had strung a maze of barbed wire from tree to tree, slowed up the retreat and pursuit. Also the density of the woods hampered observation of the enemy from the air and therefore slowed up our artillery fire. The process of taking enemy positions by frontal assault, always a costly operation, gave way, wherever possible, to infiltration, by which villages and other posts were pinched off, exactly as Cambrai, St. Quentin, Lille and other places were taken later by the British farther north. The process of infiltration from a military standpoint means exactly the same thing as the word means in any other connection. A few men at a time filter into protected positions close to the enemy until enough have assembled to offer battle, the enemy meanwhile being kept down by strong, concentrated fire from the main body and the artillery. Although much slower than an assault, this is extremely economical of men. During this progress from the Marne northward, the various headquarters had found some difficulty in keeping in touch with the advancing columns. A headquarters, even of a regiment, is not so mobile as the regiment itself. There is a vast amount of paraphernalia and supplies to be moved, yet it is necessary that a reasonably close touch be maintained with the fighting front.
