The cavalry, under General Allenby, were ordered to cover the retirement. Throughout the 25th and far into the evening, the First Corps continued its march on Landrecies, following the road along the eastern border of the Foret de Mormal, and arrived at Landrecies about 10 o'clock. I had intended that the corps should come further west so as to fill up the gap between Le Cateau and Landrecies, but the men were exhausted and could not get further in without rest. [Sidenote: British brigade in Landrecies.] [Sidenote: French reserve divisions support First Corps.] The enemy, however, would not allow them this rest, and about 9:30 P. M. a report was received that the Fourth Guards Brigade in Landrecies was heavily attacked by troops of the Ninth German Army Corps, who were coming through the forest on the north of the town. This brigade fought most gallantly, and caused the enemy to suffer tremendous loss in issuing from the forest into the narrow streets of the town. This loss has been estimated from reliable sources at from 700 to 1,000. At the same time information reached me from Sir Douglas Haig that his First Division was also heavily engaged south and east of Maroilles. I sent urgent messages to the commander of the two French reserve divisions on my right to come up to the assistance of the First Corps, which they eventually did. Partly owing to this assistance, but mainly to the skillful manner in which Sir Douglas Haig extricated his corps from an exceptionally difficult position in the darkness of the night, they were able at dawn to resume their march south toward Wassigny on Guise. By about 6 P. M. the Second Corps had got into position with their right on Le Cateau, their left in the neighborhood of Caudry, and the line of defense was continued thence by the Fourth Division toward Seranvillers, the left being thrown back. During the fighting on the 24th and 25th the cavalry became a good deal scattered, but by the early morning of the 26th General Allenby had succeeded in concentrating two brigades to the south of Cambrai. The Fourth Division was placed under the orders of the general officer commanding the Second Army Corps. On the 24th the French cavalry corps, consisting of three divisions under General Sordet, had been in billets north of Avesnes. On my way back from Bavai, which was my "Poste de Commandement" during the fighting of the 23d and 24th, I visited General Sordet, and earnestly requested his co-operation and support. He promised to obtain sanction from his army commander to act on my left flank, but said that his horses were too tired to move before the next day. Although he rendered me valuable assistance later on in the course of the retirement, he was unable for the reasons given to afford me any support on the most critical day of all, viz., the 26th.
