The German Army had as yet shown no demoralization, and, while the mass of its troops had suffered in morale, its first-class divisions, and notably its machine-gun defense, were exhibiting remarkable tactical efficiency as well as courage. The German General Staff was fully aware of the consequences of a success on the Meuse-Argonne line. Certain that he would do everything in his power to oppose us, the action was planned with as much secrecy as possible and was undertaken with the determination to use all our divisions in forcing decision. We expected to draw the best German divisions to our front and to consume them while the enemy was held under grave apprehension lest our attack should break his line, which it was our firm purpose to do.
Our right flank was protected by the Meuse, while our left embraced the Argonne Forest, whose ravines, hills, and elaborate defense, screened by dense thickets, had been generally considered impregnable. Our order of battle from right to left was the 3d Corps from the Meuse to Malancourt, with the 33d, 80th, and 4th Divisions in line and the 3d Division as corps reserve; the 5th Corps from Malancourt to Vauquois, with the 79th, 87th, and 91st Divisions in line and the 32d in corps reserve, and the 1st Corps from Vauquois to Vienne le Château, with the 35th, 28th, and 77th Divisions in line and the 92d in corps reserve. The army reserve consisted of the 1st, 29th, and 82d Divisions.
On the night of Sept. 25, our troops quietly took the place of the French, who thinly held the line in this sector, which had long been inactive. In the attack which began on the 26th we drove through the barbed-wire entanglements and the sea of shell craters across No Man's Land, mastering all the first-line defenses. Continuing on the 27th and 28th, against machine guns and artillery of an increasing number of enemy reserve divisions, we penetrated to a depth of from three to seven miles and took the village of Montfaucon and its commanding hill, and other villages. East of the Meuse one of our divisions, which was with the 2d Colonial French Corps, captured Marcheville and Rieville, giving further protection to the flank of our main body. We had taken 10,000 prisoners, we had gained our point of forcing the battle into the open, and were prepared for the enemy's reaction, which was bound to come, as he had good roads and ample railroad facilities for bringing up his artillery and reserves.
