We have seen that the British retirement (following the dotted lines upon Sketch 60) had reached, upon the Friday night, the position from Noyon to La Fère, marked also in dots upon the sketch.
What had happened meanwhile to their French colleagues upon the east?
Sketch 60.
The first thing to note is that the fortress of Maubeuge, with its garrison of reserve and second line men, had, of course, been at once invested by the Germans when the British and French line had fallen behind it and left it isolated. The imperfection of this fortress I have already described, and the causes of that imperfection. Maubeuge commanded the great railway line leading from Belgium to Paris, which is the main avenue of supply for an invasion or for a retreat, running north-east to south-west on the Belgian frontier upon the capital.
The 5th French Army retired parallel to the British along the belt marked in Sketch Map 60 by diagonal lines. At first, as its retirement had begun earlier, it was behind, or to the south of, the British, who were thus left almost unsupported. It lay, for instance, on Monday, the 24th, much along the position 1, at which moment the British Army was lying along the position 2. That was the day on which the Germans attempted to drive the British into Maubeuge.
But during the succeeding two days the French 5th Army (to which the five corps, including the Prussian Guard, under Buelow, were opposed) held the enemy fairly well. They were losing, of course, heavily in stragglers, in abandoned wounded, and in guns; but their retreat was sufficiently strongly organized to keep this section of the line well bent up northwards, and just before the British halted for their first breathing space along the line La Fère and Noyon, the French 5th Army attempted, and succeeded in, a sharp local attack against the superior forces that were pursuing them. This local attack was undertaken from about the position marked 3 on Sketch 60, and was directed against Guise. It was undertaken by the 1st and 3rd French Corps, under General Maunoury. He, acting under Lanrezac, gave such a blow to the Prussian Guard that he here bent the Prussian line right in.
Meanwhile the 4th French Army, which had also been retiring rapidly parallel to the 5th French Army, lay in line with it to the east along that continuation of 3 which I have marked with a 4 upon the sketch. Farther east the French armies, linking up the operative corner with the Alsace-Lorraine frontier, had also been driven back from the Upper Meuse, and upon Friday, the 28th of August, when the British halt had come between La Fère and Noyon (a line largely protected by the Oise), the whole disposition of the Allied forces between the neighbourhood of Verdun and Noyon was much what is laid down in the accompanying sketch. At A were the British; at B the successful counter-offensive of the French 5th Army had checked and bent back the Prussian centre under von Buelow; at C, the last section of what had been the old operative corner, the army under Langle was thrust back to the position here shown, and pressed there by the Wurtembergers and the Saxons opposed to it. Meanwhile further French forces, D and E, had also been driven back from the Upper Meuse, and were retiring with Verdun as a pivot, leaving isolated the little frontier town of Longwy. This was not seriously fortified, had held out with only infantry work and small pieces, and had not been thought worthy of attack by a siege train. It surrendered to the Crown Prince upon Friday, 28th August.
