The position was a dangerous one. It has already been stated that the pause on the Aisne may not have been unwelcome to the Germans, as they were preparing reserve formations which might be suddenly thrown against some chosen spot in the Allied line. They had the equipment and arms for at least another 250,000 men, and that number of drilled men were immediately available, some being Landwehr who had passed through the ranks, and others young formations which had been preparing when war broke out. Together they formed no less than five new army corps, available for the extreme western front, more numerous than the whole British and Belgian armies combined. This considerable force, secretly assembled and moving rapidly across Belgium, was now striking the north of the Allied line, debouching not only over the river at Menin, but also through Courtrai, Iseghem, and Roulers. It consisted of the 22nd, 23rd, 24th, 26th, and 27th reserve corps. Of these the 22nd, and later the 24th, followed the {236} Belgians to the line of the Yser, but the other corps were all available for an attack upon the flank of that British line which was faced by formidable opponents--a line which extended over thirty miles and had already been forced into a defensive attitude. That was the situation when the Seventh Division faced round near Ypres. Sir John French was doing all that he could to support it, and Sir Douglas Haig was speeding up his army corps from the Aisne to take his place to the north of Ypres, but there were some days during which Rawlinson's men were in the face of a force six or seven times larger than themselves.
