About this time, the 10th Hussars were moved across the Namur road, and down the slope in front where they were halted, in _echelon_ of Squadrons; and while they were thus posted, WELLINGTON and his Staff came to the front of the Regiment. From this spot the Duke was attentively watching, through his telescope, the dispositions and movements of the French, whom he could discover as soon as they reached the Quatre Bras side of Little Marbais; when all at once at a distance of about two miles, masses were seen forming on the side of the Namur road, conspicuously glittering in the sun's rays; by which the Duke was at first induced to believe that they were Infantry, whose bayonets were so brilliantly reflected; but it was soon discovered that they were _Cuirassiers_. After a short time, these were observed to advance, preceded by Lancers, and it was not long before the Picquet of the 18th British Hussars, posted on that road, began skirmishing, as did also the Picquet of the 10th British Hussars, more in the front of the position, and likewise, still further to the right, in front of Quatre Bras, a Picquet consisting of a Squadron of the 11th British Light Dragoons, detached from Major General VANDELEUR's Brigade, which comprised the 11th Light Dragoons (under Lieutenant Colonel SLEIGH), the 12th Light Dragoons (under Colonel the Hon. FREDERICK PONSONBY), and the 16th Light Dragoons (under Lieutenant Colonel HAY). The 10th Hussars then fell back again into their proper place in the line. VIVIAN now took up a new alignment, throwing back his Left so as to present a front to the Enemy's advance, and to protect the left of the position. VANDELEUR's Brigade was then in Right Rear of VIVIAN's and close to Quatre Bras. The Anglo-Allied Infantry having, some time previously, entirely crossed the Genappe, with the exception of the Light Companies of the Second Brigade of Guards on the right, and of the 1st Battalion 95th British Regiment (Rifles), on the left, which troops had been directed to remain until the last moment, and were now retiring to Genappe (where they were subsequently drawn up at the entrance of the town), and the Duke having satisfied himself that a formidable body of the French Cavalry was endeavouring to fall upon him and to molest his retreat, it became a question with his Grace, at that moment, how far it might be advisable to offer any serious resistance to the advance of the Enemy; but Lieutenant General the Earl of UXBRIDGE, the Commander of the Anglo-Allied Cavalry, having remarked that, considering the defiles in the rear, and the distance to which the great mass of the Infantry had already retired and from which it could offer no immediate support, he did not think the Cavalry was favourably situated for making such an attempt, the Duke assented to the correctness of this view, and requested his Lordship at once to carry into effect the retreat of the Cavalry.
