At length, the attack evinced symptoms of exhaustion; the charges became less frequent and less vigorous; disorder and confusion were rapidly augmenting; the spirit of enthusiasm and the confidence of superiority were quickly yielding to the feeling of despondency and the sense of hopelessness. The Anglo-Allied Cavalry again advanced, and once more swept the mingled host, comprising every description of mounted troops, from off the ground on which they had so fruitlessly frittered away their strength. On this occasion, a body of _Cuirassiers_, having been intercepted in its direct line of retreat by a party of British Light Dragoons, was induced to surrender; but taking advantage of the weakness of their escort, they suddenly broke away, and galloped down the Nivelles road, by which they hoped to return to the French Lines. They were fatally deceived. As they passed the high bank, covered with brushwood, on the right of the road, where a Detachment of the 51st Regiment was stationed as one of the Supports to the Light Troops extended in front of the extreme Right, they were fired upon, though but partially, in consequence of their close pursuit by the Light Dragoons. This attracted the attention of Captain Ross of that Regiment, who was posted with his Company more in advance, and close to the _abatis_ which had been thrown across the road near the head of the Avenue leading to Hougomont. Captain Ross, being thus prepared, also fired upon the _Cuirassiers_; whereupon their Commanding Officer, finding all further retreat effectually cut off by the _abatis_, surrendered to Captain Ross, declaring that he would not give himself up to the Dragoons. At this spot eighty of the _Cuirassiers_ and twelve of their horses were killed; and the remainder, about sixty, were dismounted, taken, or dispersed. * * * * * Shortly before this, NEY, perceiving the ill success of his Cavalry attacks, determined on combining them with such Infantry as he had at his disposal. Between D'ERLON's and REILLE's Corps there was now a great interval, and the only troops of which he could make use for the above object, consisted of BACHELU's Division, on the right of the latter, as DONZELOT's Division, on the left of the former, was still required for the attack upon La Haye Sainte, which he now ordered to be vigorously renewed, whilst he advanced a heavy Column of BACHELU's Infantry towards the Centre of the Allied Right Wing.
