Then Foch attacked. As rapidly as his line of blue men had come up to strengthen the British Front after the German break-through—I shall never forget the ride of the French Cavalry, on lean horses wet with sweat, and the hurried tide of blue transport waggons, driven by coal-black negroes, and the endless line of guns with dusty, sullen gunners coming to support us when our men had fought back for three frightful weeks—he withdrew them from our Front. They vanished like a dream army. English and Scottish Divisions were entrained for the French Front. Our own lines were thin and weak. Foch was taking the ultimate risks. American infantry and American Marines were put in at Chateau Thierry for their baptism of blood. French infantry, withdrawn from other parts of the line, left almost without defence, were rushed to the Marne. The German salient thrust out like a battering ram, pointing to Paris, was attacked on both sides, at its junctions with the main line. It was pierced and broken. The enemy was panic-stricken and thrown into a mad disorder. “Who attacked?” asked German prisoners. “Foch’s Army of Reserve,” was the answer. “He has no Reserves!” they said with rage. “It was impossible for him to have an Army of Reserve.” It was an Army of Reserve gathered piecemeal, flung together, hurled forward in a master stroke of strategy, at the last minute of the eleventh hour. It was the second “Miracle” of the Marne. That battle broke the spirit of the German people and of the German army. They knew that only retreat and defeat lay ahead of them. They had struck their last great blow and it had failed. They had used up their man-power. They, certainly, had no Army of Reserve. They could only hope that the French and British were as exhausted as themselves and that the Americans were still unready. They prepared for a general retreat when the British army took the offensive of August, 1918, and never stopped fighting along the whole length of its line until the day of armistice, while the French and Americans pressed the Germans on their own front.
