In one of these affairs, Captain HEYLIGER of the 7th Hussars, made a very brilliant charge with his Troop; and when the Duke of WELLINGTON sent to check him, his Grace desired to be made acquainted with the name of an Officer who had displayed so much gallantry. A very spirited charge was also made by the Right Troop of the 2nd Light Dragoons of the King's German Legion, under Lieutenant HUGO; who was allowed by his Commanding Officer to volunteer for that service, and who, from the vicinity of Hougomont, boldly rushed up the Height intervening between that point and Mon Plaisir, and gallantly drove back a portion of the French Advanced Guard of Cavalry; recapturing at the same time three carriages filled with British sick and wounded. * * * * * The manner in which the Duke of WELLINGTON withdrew his Army from the position of Quatre Bras to the one of Waterloo, must ever render that retreat a perfect model of operations of this nature, performed in the immediate presence of a powerful Enemy. Those dispositions which have been described as having been made by him for the purpose of masking the retirement of the main body, of affording perfect security to the passage of the Defile in his rear, and of ensuring the orderly and regular assembly of the several Corps on the ground respectively allotted to them in the new position, evince altogether a degree of skill which has never been surpassed. In such operations, the covering of the Army by its Cavalry and Light Troops necessarily forms an important feature; and a glance at the manner in which this duty was fulfilled by the Earl of UXBRIDGE, with the Cavalry, Horse Artillery, and a few Light Battalions, at his disposal, is sufficient to show that the exemplification of such feature on this occasion was exceedingly beautiful. Indeed, so orderly and so perfect were all the arrangements connected with this retreat, from its commencement to its close, that the movements partook more of the appearance of a Field Day upon a large scale, than of an operation executed in the actual presence of an Enemy; and this was particularly observable as regarded the protection afforded by the Cavalry and Horse Artillery, which manoeuvred to admiration, and in a style that, combined with the brilliant charge by the 1st Life Guards at Genappe, evidently impressed the Enemy with a due sense of the efficiency of the gallant troops immediately in his front. It may here also be remarked, that the judicious dispositions made by Lord UXBRIDGE in covering this retreat, and the high degree of confidence with which he inspired the Cavalry, afforded well grounded anticipations of the success likely to attend his measures when conducting that Cavalry in the open battle field, on which, it was foreseen, its prowess would so very soon be tested. The British and German portion of the Cavalry was in excellent order, and seemed already to have imbibed, in a high degree, that
