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. On the 24th, after the Germans had fallen back from Trugny 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 co-operating were moving forward at other points. The Third Division had made its advance into Roncheres Wood on the 29th and was relieved for rest by a brigade of the Thirty-second. The Forty-second and Thirty-second undertook the task of conquering the heights beyond Cierges, the Forty-second capturing Sergy and the Thirty-second capturing Hill 230, both American divisions joining in the pursuit of the enemy to the Vesle, and thus the operation of reducing the salient was finished. Meanwhile the Forty-second was relieved by the Fourth at Chery-Chartreuve, and the Thirty-second by the Twenty-eighth, while the Seventy-seventh Division took up a position on the Vesle. The operations of these divisions on the Vesle were under the Third Corps, Maj. Gen. Robert L. Bullard, commanding. BATTLE OF ST. MIHIEL. With the reduction of the Marne salient we could look forward to the concentration of our divisions in our own zone. In view of the forthcoming operation against the St. Mihiel salient, which had long been planned as our first offensive action on a large scale, the First Army was organized on August 10 under my personal command. While American units had held different divisional and corps sectors along the western front, there had not been up to this time, for obvious reasons, a distinct American sector; but, in view of the important parts the American forces were now to play, it was necessary to take over a permanent portion of the line. Accordingly, on August 30, the line beginning at Port sur Seille, east of the Moselle and extending to the west through St. Mihiel, thence north to a point opposite Verdun, was placed under my command. The American sector was afterwards extended across the Meuse to the western edge of the Argonne Forest, and included the Second Colonial French, which held the point of the salient, and the Seventeenth French Corps, which occupied the heights above Verdun. PREPARATION FOR THE ATTACK.
