It was soon after this that NEY received another despatch from NAPOLEON, dated at two o'clock. From its general tenor it was evidently written previously to the departure of Colonel LAURENT with the Order for the flank movement of D'ERLON's Corps, and therefore the bearer of it must have taken longer time than was necessary in conveying it to the Marshal. It announced that the Prussians were posted between Sombref and Bry, and that at half past two GROUCHY was to attack them with the Third and Fourth _Corps d'Armée_, and expressed the Emperor's wish that NEY should also attack whatever Enemy might be in his front, and, after having repulsed the latter, fall back in the direction of Ligny, to assist in enveloping the Prussians. At the same time it stated, that should NAPOLEON succeed in defeating the latter beforehand, he would then manoeuvre in NEY's direction, to support in like manner the Marshal's operations. It concluded by requesting information both as to NEY's own dispositions and those of the Enemy in his front. This despatch reached NEY at a moment when he was most seriously engaged, when the issue of the battle was extremely doubtful, and the probability of his being enabled to afford the support required by NAPOLEON most questionable. Upon the extreme Left of the Anglo-Allied forces, the advance of the French Light Troops from Piermont and its vicinity was met in a most determined and gallant manner by the head of KIELMANSEGGE's Hanoverian Brigade (which after having moved along the Nivelles road, exposed to the continued fire from the Batteries on the French Heights, had just reached that part of the field), in conjunction with the 1st Battalion 95th British Rifles, and the 2nd Brunswick Light Battalion. The most determined efforts were made by the Enemy to turn the Anglo-Allied Flank. The French Infantry had already gained the high road, and were boldly pressing forward, when the British Rifles, the Brunswick Light Infantry, and the Hanoverian Field Battalion Lüneburg (under Lieutenant Colonel KLENCKE) dashed in amongst them. The contest was obstinate and severe; but the Allied Light Troops having been reinforced by the Hanoverian Field Battalion Grubenhagen (under Lieutenant Colonel WURMB), gradually obtained the ascendancy, and, dislodging their opponents from one inclosure after another, continued steadily advancing, and gaining ground. Along the whole front of the central portion of the Anglo-Allied Army, the French Cavalry was expending its force in repeated but unavailing charges against the indomitable Squares. The gallant, the brilliant, the heroic, manner in which the remnants of KEMPT's and PACK's Brigades held their ground, of which they surrendered not a single inch throughout the terrific struggle of that day, must ever stand pre-eminent in the records of the triumphs and prowess of British Infantry.
