Zieten’s advance infantry pushed down into the valley, where some shots were exchanged by mistake between them and the Nassau troops: the mistake was soon rectified, and both bodies united advanced, and dislodged the French from the houses in the valley of Smohain, and the farms of La Haye and Papelotte. It was about eight o’clock, when Zieten’s advance cavalry drew up on our left, and an infantry brigade and the reserve cavalry of general Pirch’s (second) corps joined Bulow, and in conjunction made the following dispositions for the third attack upon Plancenoit: General Ryssel’s and colonel Hiller’s infantry brigades of the 4th corps under general count Bulow, and general Tippelskircher’s brigade of general Pirch’s (second) corps, formed in columns of battalions; on the left was a regiment of prince William’s reserve, and two battalions of infantry with their skirmishers in front; and three cavalry regiments, part of prince William’s, were in rear of the above brigades. In rear of this cavalry was general Krafft’s infantry brigade of the 2d corps in reserve; and on the right of the infantry brigades were three lines of cavalry, under general Jurgass; and upon their right, and advancing simultaneously with the attack upon Plancenoit, were Hack’s and Losthin’s infantry brigades of the 4th corps; in their rear were three battalions, part of Hack’s brigade. On the right of those brigades was a small force of cavalry, part of prince William’s, and upon their right were four battalion columns, part of general Steinmetz’s brigade of general Zieten’s (first) corps. Upon the ridge on the allied left, was part of general Röder’s cavalry that had just reached the field, and whose battery opened fire in place of one belonging to the allies that had expended all its ammunition. A few battalions were detached to the left of Plancenoit, to secure the flank, and, if possible, to turn the enemy’s right. The whole Prussian force was preceded by skirmishers, and their batteries were most advantageously placed upon the heights. A squadron of Prussian cavalry beat back a company of the Imperial guard from the farm of Chantilly, above Plancenoit. The latter retired upon the wood at the farm of Caillou, closely pursued by the hostile cavalry, which was beaten off by the Imperial baggage guard. The Prussian dragoons soon returned in such force, that the Emperor’s suite, with bag and baggage, made a hasty flight towards Genappe. Whilst Blücher’s army stood as stated, Wellington had defeated both the attacking columns of the Imperial guard; and Adam’s brigade was driving them and Donzelot’s division, that had broken and mixed with them, across the field, toward the Genappe high-road. Vivian’s brigade and the 2d German light dragoons were setting forward at a long trot towards the French reserves, drawn up between La Belle-Alliance and Hougoumont.
