Such then was the disposition of the 2nd A.C. The 1st A.C. lay back, as has been explained, almost at right angles to the line of the canal, along the two roads that branch off from Mons to Beaumont and Maubeuge respectively. On the first-named road was the 1st Division reaching as far as Grand Reng. This division, however, as events turned out, was merely a spectator of the operations of August 23rd. The 2nd Division was very much scattered, the 6th Brigade being at Givry, and the 5th at Bougnies, while of the 4th Brigade the two Coldstream Battalions were at Harveng and the rest of the brigade at Quévy.
The gap between the 1st and 2nd A.C. was patrolled by the 2nd C.B., an operation which brought about the first actual collision between British and German troops. This was on the 22nd near Villers St. Ghislain, when Captain Hornby with a squadron of the 4th Dragoon Guards fell in with a column of Uhlans, which he promptly charged and very completely routed, capturing a number of prisoners.
The rest of our cavalry was spread along the Binche road as a covering screen for the 1st A.C., with the exception of the 4th C.B. which was at Haulchin cross-roads, guarding the approach to that place from the direction of Binche, and at the same time keeping up a communication between the 1st and 2nd Divisions.
Such then was, generally speaking, the position on August 22nd. During that night, however, all the cavalry was withdrawn from the Binche road and moved across to the left of our line, where they took up a position guarding that flank along the two roads running north and south through Thulin and Eloges to Andregnies. The 4th C.B., having the shortest journey to make, went four miles further west again to Quiverain. This change of position meant a twenty mile night march for the cavalry on the top of a hard day's patrol work, and the journey took them from six o'clock in the evening till two o'clock the following morning.
The morning of the 23rd opened sunny and bright. The weather was set fair with a breeze from the east, a cloudless sky, and the promise of great heat at midday. A pale blue haze rounded off the distance, and softened the outlines of the tall, gaunt chimney stacks with which the entire country is dotted.
