After four hours' artillery preparation, the seven American divisions in the front line advanced at 5 A. M. on Sept. 12, assisted by a limited number of tanks, manned partly by Americans and partly by French. These divisions, accompanied by groups of wire cutters and others armed with bangalore torpedoes, went through the successive bands of barbed wire that protected the enemy's front-line and support trenches in irresistible waves on schedule time, breaking down all defense of an enemy demoralized by the great volume of our artillery fire and our sudden approach out of the fog.
Our 1st Corps advanced to Thiaucourt, while our 4th Corps curved back to the southwest through Nonsard. The 2d Colonial French Corps made the slight advance required of it on very difficult ground, and the 5th Corps took its three ridges and repulsed a counterattack. A rapid march brought reserve regiments of a division of the 5th Corps into Vigneulles and beyond Fresnes-en-Woevre. At the cost of only 7,000 casualties, mostly light, we had taken 16,000 prisoners and 443 guns, a great quantity of material, released the inhabitants of many villages from enemy domination, and established our lines in a position to threaten Metz. This signal success of the American First Army in its first offensive was of prime importance. The Allies found they had a formidable army to aid them, and the enemy learned finally that he had one to reckon with.
Meuse-Argonne Offensive, First Phase
On the day after we had taken the St. Mihiel salient much of our corps and army artillery which had operated at St. Mihiel, and our divisions in reserve at other points, were already on the move toward the area back of the line between the Meuse River and the western edge of the Forest of Argonne. With the exception of St. Mihiel the old German front line from Switzerland to the east of Rheims was still intact. In the general attack all along the line the operations assigned the American Army as the hinge of this allied offensive were directed toward the important railroad communications of the German armies through Mézières and Sedan. The enemy must hold fast to this part of his lines, or the withdrawal of his forces, with four years' accumulation of plants and material, would be dangerously imperiled.
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 Exermont, Gercourt, Cuisy, Septsarges, Malancourt, Ivoiry, Epinonville, Charpentry, Very, 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.
In the chill rain of dark nights our engineers had to build new roads across spongy, shell-torn areas, repair broken roads beyond No Man's Land, and build bridges. Our gunners, with no thought of sleep, put their shoulders to wheels and drag ropes to bring their guns through the mire in support of the infantry, now under the increasing fire of the enemy's artillery. Our attack had taken the enemy by surprise, but, quickly recovering himself, he began to fire counter-attacks in strong force, supported by heavy bombardments, with large quantities of gas. From Sept. 28 until Oct. 4 we maintained the offensive against patches of woods defended by snipers and continuous lines of machine guns, and pushed forward our guns and transport, seizing strategical points in preparation for further attacks.
Other Units with Allies
Other divisions attached to the allied armies were doing their part. It was the fortune of our 2d Corps, composed of the 27th and 30th Divisions, which had remained with the British, to have a place of honor in co-operation with the Australian Corps on Sept. 29 and Oct. 1 in the assault on the Hindenburg line where the St. Quentin Canal passes through a tunnel under a ridge. The 30th Division speedily broke through the main line of defense for all its objectives, while the 27th pushed on impetuously through the main line until some of its elements reached Gouy. In the midst of the maze of trenches and shell craters and under crossfire from machine guns the other elements fought desperately against odds. In this and in later actions, from Oct. 6 to Oct. 19, our 2d Corps captured over 6,000 prisoners and advanced over thirteen miles. The spirit and aggressiveness of these divisions have been highly praised by the British Army commander under whom they served.
