The sector occupied a position in what the French called the Pont-a-Mousson front. Our men were to occupy an eight-mile section of the front line trenches extending from a point west of the town of Flirey, to a point west of the ruins of the town of Seicheprey. The position was not far from the French stronghold of Verdun to the northwest or the German stronghold of Metz to the northeast, and was equidistant from both. That line changed from French blue to American khaki on the night of January 21st. The sector became American at midnight. I watched the men as they marched into the line. In small squads they proceeded silently up the road toward the north, from which direction a raw wind brought occasional sounds resembling the falling of steel plates on the wooden floor of a long corridor. A half moon doubly ringed by mist, made the hazy night look grey. At intervals, phantom flashes flushed the sky. The mud of the roadway formed a colourless paste that made marching not unlike skating on a platter of glue. This was their departure for the front--this particular battalion--the first battalion of the 16th United States Infantry. I knew, and every man in it knew, what was before them. Each man was in for a long tour of duty in trenches knee-deep with melted snow and mud. Each platoon commander knew the particular portion of that battle-battered bog into which he must lead his men. Each company commander knew the section of shell-punctured, swamp land that was his to hold, and the battalion commander, a veteran American soldier, was well aware of the particular perils of the position which his one thousand or more men were going to occupy in the very jaw-joint of a narrowing salient. All branches of the United States military forces may take special pride in that first battalion that went into the new American line that night. The commander represented the U. S. Officers Reserve Corps, and the other officers and men were from the reserves, the regulars, West Point, the National Guard and the National Army. Moreover, the organisation comprised men from all parts of the United States as well as men whose parents had come from almost every race and nationality in the world. One company alone possessed such a babble of dialects among its new Americans, that it proudly called itself, the Foreign Legion. For two days the battalion had rested in the mud of the semi-destroyed village of Ansauville, several miles back of the front. A broad, shallow stream, then at the flood, wound through and over most of the village site. Walking anywhere near the border of the water, one pulled about with him pounds of tenacious, black gumbo. Dogs and hogs, ducks and horses, and men,--all were painted with nature's handiest camouflage.
