Having regard to the continued retirement of the French on my right, my exposed left flank, the tendency of the enemy's western corps (II) to envelop me, and, more than all, the exhausted condition of the troops, I determined to make a great effort to continue the retreat till I could put some substantial obstacle, such as the Somme or the Oise, between my troops and the enemy, and afford the former some opportunity of rest and reorganisation. Orders were, therefore, sent to the Corps Commanders to continue their retreat as soon as they possibly could towards the general line Vermand-St. Quentin-Ribemont.
The Cavalry, under General Allenby, were ordered to cover the retirement.
Throughout the 25th and far into the evening, the 1st Corps continued its march on Landrecies, following the road along the eastern border of the Forêt 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.
The enemy, however, would not allow them this rest, and about 9.30 p.m. a report was received that the 4th Guards Brigade in Landrecies was heavily attacked by troops of the 9th 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 1st 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 1st Corps, which they eventually did. Partly owing to this assistance, but mainly to the skilful 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 towards Wassigny on Guise.
By about 6 p.m. the 2nd Corps had got into position with their right on Le Cateau, their left in the neighbourhood of Caudry, and the line of defence was continued thence by the 4th Division towards 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 4th Division was placed under the orders of the General Officer Commanding the 2nd Army Corps.
On the 24th the French Cavalry Corps, consisting of three divisions, under General Sordêt, had been in billets north of Avesnes. On my way back from Bavai, which was my "Poste de Commandement" during the fighting of the 23rd and 24th, I visited General Sordêt, 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.
At daybreak on August 26 it became apparent that the enemy was throwing the bulk of his strength against the left of the position occupied by the 2nd Corps and the 4th Division.
At this time the guns of four German Army Corps were in position against them, and Sir Horace Smith-Dorrien reported to me that he judged it impossible to continue his retirement at daybreak (as ordered) in face of such an attack.
