When the news of the retirement of the French and the heavy German threatening on my front reached me, I endeavored to confirm it by aeroplane reconnoissance; and as a result of this I determined to effect a retirement to the Maubeuge position at daybreak on the 24th. A certain amount of fighting continued along the whole line throughout the night and at daybreak on the 24th the Second Division from the neighborhood of Harmignies made a powerful demonstration as if to retake Binche. This was supported by the artillery of both the First and Second Divisions, while the First Division took up a supporting position in the neighborhood of Peissant. Under cover of this demonstration the Second Corps retired on the line Dour-Quarouble-Frameries. The Third Division on the right of the corps suffered considerable loss in this operation from the enemy, who had retaken Mons. The Second Corps halted on this line, where they partially intrenched themselves, enabling Sir Douglas Haig with the First Corps gradually to withdraw to the new position; and he effected this without much further loss, reaching the line Bavai-Maubeuge about 7 P. M. Toward midday the enemy appeared to be directing his principal effort against our left. I had previously ordered General Allenby with the cavalry to act vigorously in advance of my left front and endeavor to take the pressure off. [Sidenote: General Allenby supports Fifth Division.] About 7:30 A. M. General Allenby received a message from Sir Charles Fergusson, commanding the Fifth Division, saying that he was very hard pressed and in urgent need of support. On receipt of this message General Allenby drew in the cavalry and endeavored to bring direct support to the Fifth Division. During the course of this operation General De Lisle, of the Second Cavalry Brigade, thought he saw a good opportunity to paralyze the further advance of the enemy's infantry by making a mounted attack on his flank. He formed up and advanced for this purpose, but was held up by wire about 500 yards from his objective, and the Ninth Lancers and the Eighteenth Hussars suffered severely in the retirement of the brigade. The Nineteenth Infantry Brigade, which had been guarding the line of communications, was brought up by rail to Valenciennes on the 22d and 23d. On the morning of the 24th they were moved out to a position south of Quarouble to support the left flank of the Second Corps. [Sidenote: Sir Horace Smith-Dorrien suffers great losses.] With the assistance of the cavalry Sir Horace Smith-Dorrien was enabled to effect his retreat to a new position; although, having two corps of the enemy on his front and one threatening his flank, he suffered great losses in doing so.
