about from the wood, it was attacked by French cavalry on the plain, but formed square, and repelled several charges. As the vigour of the French attacks began to slacken, the Battalion cleared its way with the bayonet through the cavalry that continued hovering round it. One of its companies extended itself along the edge of the wood, and kept the French cavalry at bay. The French cavalry suffered severely on this occasion. General Letort who led the attacks was mortally wounded and died two days later on 17 June. Historians such as Philip Haythornthwaite postulate that if Letort had been present at Waterloo on 18 June, he might have affected the great French cavalry charge, and perhaps the outcome of the battle. The Brandenburg Dragoons (Watzdorf's) had been detached by Zieten in support of the 2nd Brigade (Pirch II's), and opportunely reaching the field of action, they made several charges against the French cavalry, which was repulsed, ending its pursuit of the Prussian infantry. The 2nd Brigade (Pirch II's) now took up a position in front of Lambusart, which was occupied by some battalions of the 3rd Brigade (Jagow's). General Röder joined it with his remaining three regiments of cavalry and a battery of horse artillery. At this moment the French cavalry, which was formed up in position, opened a fire from three batteries of horse artillery. This brought on a cannonade, with which the affair was terminated. Prussian retreat is concluded The Prussian 1st Brigade (Steinmetz's) having safely executed its retreat from Heppignies towards Fleurus, reached Saint-Amand about 23:00. The detachments left by the 3rd Brigade (Jagow's) at Farciennes and Tamines, had also effected their retreat without incident as did the 2nd Brigade (Pirch II's) from Lambusart, by , towards Fleurus, being protected by the reserve cavalry. By 03:00 I Corps (Zieten's), had established a line of advanced posts in length, from Dinant on the Meuse, crossing the Sambre at Thuin, and extending as far as Bonne-Espérance in advance of Binche. The main force occupied the Sambre from Thuin as far as its confluence with the Meuse, an extent of at least, , exclusive of the numerous windings by the river between those two points. Since daybreak the Prussians of I Corps had been constantly pursued and engaged by a superior French force, headed by the elite of the French cavalry. It was not until about 23:00 that
