The concentration was practically complete on the evening of Friday, the 21st ultimo, and I was able to make dispositions to move the Force during Saturday, the 22nd, to positions I considered most favourable from which to commence operations which the French Commander-in-Chief, General Joffre, requested me to undertake in pursuance of his plans in prosecution of the campaign. Position at Mons The line taken up extended along the line of the canal from Condé on the west, through Mons and Binche on the east. This line was taken up as follows:-- From Condé to Mons inclusive was assigned to the Second Corps, and to the right of the Second Corps from Mons the First Corps was posted. The 5th Cavalry Brigade was placed at Binche. In the absence of my Third Army Corps I desired to keep the Cavalry Division as much as possible as a reserve to act on my outer flank, or move in support of any threatened part of the line. The forward reconnaissance was entrusted to Brigadier-General Sir Philip Chetwode with the 5th Cavalry Brigade, but I directed General Allenby to send forward a few squadrons to assist in this work. During the 22nd and 23rd these advanced squadrons did some excellent work, some of them penetrating as far as Soignies, and several encounters took place in which our troops showed to great advantage. Sunday, August 23 2. At 6 a.m., on August 23rd, I assembled the Commanders of the First and Second Corps and Cavalry Division at a point close to the position, and explained the general situation of the Allies, and what I understood to be General Joffre's plan. I discussed with them, at some length the immediate situation in front of us. From information I received from French Headquarters I understood that little more than one, or at most two, of the enemy's Army Corps, with perhaps one Cavalry Division, were in front of my position; and I was aware of no attempted outflanking movement by the enemy. I was confirmed in this opinion by the fact that my patrols encountered no undue opposition in their reconnoitring operations. The observation of my aeroplanes seemed also to bear out this estimate. About 3 p.m. on Sunday, the 23rd, reports began coming in to the effect that the enemy was commencing an attack on the Mons line, apparently in some strength, but that the right of the position from Mons and Bray was being particularly threatened. The Commander of the First Corps had pushed his flank back to some high ground south of Bray, and the 5th Cavalry Brigade evacuated Binche, moving slightly south: the enemy thereupon occupied Binche.
