The great force of the German Chateau-Thierry offensive established the deep Marne salient, but the enemy was taking chances, and the vulnerability of this pocket to attack might be turned to his disadvantage. Seizing this opportunity to support my conviction, every division with any sort of training was made available for use in a counter-offensive. The place of honor in the thrust toward Soissons on July 18 was given to our First and Second Divisions in company with chosen French divisions. Without the usual brief warning of a preliminary bombardment, the massed French and American artillery, firing by the map, laid down its rolling barrage at dawn while the infantry began its charge. The tactical handling of our troops under these trying conditions was excellent throughout the action. The enemy brought up large numbers of reserves and made a stubborn defense both with machine guns and artillery, but through five days' fighting the First Division continued to advance until it had gained the heights above Soissons and captured the village of Berzy-le-Sec. The Second Division took Beau Repaire farm and Vierzy in a very rapid advance and reached a position in front of Tigny at the end of its second day. These two divisions captured 7,000 prisoners and over 100 pieces of artillery. [Sidenote: The Twenty-sixth and the Third.] The Twenty-sixth Division, which, with a French division, was under command of our First Corps, acted as a pivot of the movement toward Soissons. On the 18th it took the village of Torcy while the Third Division was crossing the Marne in pursuit of the retiring enemy. The Twenty-sixth attacked again on the 21st, and the enemy withdrew past the Chateau-Thierry-Soissons road. The Third Division, continuing its progress, took the heights of Mont St. Pere and the villages of Charteves and Jaulgonne in the face of both machine-gun and artillery fire. [Sidenote: Germans fall back.] [Sidenote: The Forty-second relieves the Twenty-sixth.] [Sidenote: Third and Fourth Advance.] On the 24th, after the Germans had fallen back from Trugney and Epieds, our Forty-second Division, which had been brought over from the Champagne, relieved the Twenty-sixth and, fighting its way through the Foret de Fere, overwhelmed the nest of machine guns in its path. By the 27th it had reached the Ourcq, whence the Third and Fourth Divisions were already advancing, while the French divisions with which we were cooperating were moving forward at other points. [Sidenote: The Forty-second and Thirty-second.] [Sidenote: The Twenty-eighth and the Seventy-seventh.]
