The infantry continued its valiant and persistent see-sawing. On the 29th they made a big swing on the right, and on the left took a _dépôt de machines_, or roundhouse, and the treacherous ravine south of Binarville in which it was situated, by hard and audacious fighting. On the 30th the whole line again made progress, against machine-gunners who had cunningly prepared paths to give them visibility for a greater distance, and to draw the attackers into the line of their fire. They charged down the slopes of the Charlevaux ravine and its irregular branches, across the streams and swamps at their bottoms, and up the slopes on the other side--all this through woods and thickets, of course. The next day an even deeper advance was made over very irregular ground, while the right in triumphant ardor pressed forward, ahead of the left and center, across the Fontaine-aux-Charmes ravine and its branches and their streams until it was past the heights of the Chêne Tondu. As the Chêne Tondu was not yet wholly in the possession of the division on the right, the gallant victors deserved something better in their weariness than to be forced to retire by overwhelming fire in flank and rear from the commanding heights. The night of October 1st the "Liberty" men, after six days in which they had steadily advanced for a depth of six miles, held the line from the Chêne Tondu across the Forest to a point north of Binarville, its supporting flanks on either edge of the Forest in a deadlock. There was forest and still more forest ahead of the 77th. After it had conquered the Argonne, it might have a chance to take the Bourgogne Wood beyond on the way to the Lille-Metz railway. After this experience the New Yorkers ought not to be afraid to go into Central Park after dark when they returned home. They may have thought that the 28th on their right was not keeping up to program, and the 28th may have thought that they were not; but neither had the advantage that I had of seeing the other in action during those terrible days. Astride the Aire river, having the trough as its very own, the 28th put a heart of iron into its first impact, and tempered it to steel in its succeeding attacks. The "scalloping" process which was its mission looked just as simple on a flat map as the swing toward the Meuse of the 33rd; but then, everything looked simple on the map, and everything for all the divisions might have been as simple as it looked if it had not been for the enemy. He was always interfering with our staff plans. If the Aire's course had been straight, and the valley walls had come down symmetrically to the river bottom, the 28th would have had straight open fighting, which is a satisfaction to brave men whatever the cost. A direct frontal attack was as out of the question for the Pennsylvanians as it was mandatory for the 77th. They must exhibit suppleness and cunning, or bull-dog grit was of no service.
