JEROME now moved down fresh Columns to reinforce his Skirmishers. They were directed more against the Allied Right of the Wood, while a part of FOY's Division was ordered to support the attack by a simultaneous advance against the front. The descent of JEROME's troops was observed from the position of the extreme Right of the Allied Second Line, which afforded a partial view up the valley on that side of Hougomont. Two guns were therefore detached, under Captain NAPIER, from Captain BOLTON's Battery, to open a fire upon the advancing Columns; but they were instantly cannonaded by the Batteries on the French Extreme Left, particularly by the Horse Battery of PIRÉ's Light Cavalry, on the Height intersected by the Nivelles road. The remaining guns of the Battery were brought into action, as were also those of Major SYMPHER's Hanoverian Horse Battery; and a vigorous fire was now maintained against both the attacking troops and the French guns. Lieutenant Colonel WEBBER SMITH, whose British Horse Battery was also with CLINTON's Division, but lower down the slope, commenced firing up the valley, across the Nivelles road, at one of JEROME's Columns; but on ascertaining that the latter was somewhat beyond the effectual range of his six pounders, he detached an Officer to the right of the Front Line in rear of Hougomont, to discover whether a more commanding position could be obtained for his Battery on that part of the Field. In the mean time, JEROME's Skirmishers, having been very strongly reinforced, renewed their attack upon the Wood, in conjunction with FOY's Infantry on their right. The Light Companies of the British Guards presented a stout and desperate resistance, but were forced to yield to an overwhelming superiority of numbers. Retiring from tree to tree, and frequently hazarding a bold and obstinate stand, by which they suffered most severely, they at length withdrew from the unavailing contest: those of the Coldstream and 3rd Regiment seeking shelter partly in the Lane adjoining the right of the Château, and partly behind a Haystack which fronted the Wood near the south-west angle of the buildings; while those of the 1st Regiment fell back into the Great Orchard, on the left.
