BLÜCHER, who had arrived upon the spot from his Right, having, in consequence of this sudden turn of affairs, been under the necessity of relinquishing his meditated attack upon the French Left, now made a last effort to stem the further advance of the Enemy, and, if possible, to force him back upon Ligny. The rain having ceased, it became lighter, and the Enemy's Columns being more clearly discernible, the Prince immediately ordered the advance of three Regiments of the Cavalry attached to the First _Corps d'Armée_, namely, the 6th Uhlans, the 1st West Prussian Dragoons, and the 2nd Kurmark Landwehr Cavalry. These Regiments, which constituted the only Cavalry force immediately at hand, had for some time been posted in reserve, and had suffered severely from their exposure to the fire from the French Artillery. Lieutenant General RÖDER directed the 6th Uhlans to make the first charge. The Regiment was led on by Lieutenant Colonel LÜTZOW, to whose Brigade it belonged. In the charge which was directed upon the Enemy's Infantry, LÜTZOW and several of his Officers fell under a volley of musketry. The Regiment, which was about 400 strong, lost on this occasion 13 Officers and 70 men. A second attack, made by the 1st West Prussian Dragoons, and supported by the 2nd Kurmark Landwehr Cavalry, seemed to offer a fair prospect of penetrating the French Infantry, when the former Regiment was unexpectedly charged in flank by the Enemy's _Cuirassiers_, and completely dispersed. The Westphalian, and 1st Kurmark Landwehr Cavalry, with several other Squadrons of the Landwehr, were collected together, and formed a mass of twenty four Squadrons, with which a further attack was made upon the Enemy, but without success. The cause of this failure is to be attributed not to the want of sufficient Cavalry, for indeed there was an ample number for the purpose, but to the confusion and disorder consequent upon the surprise which the Enemy's attack had occasioned, and which was augmented by the darkness that had set in upon the Field. Nor was the failure caused by the absence of that most essential requisite in a charge of Cavalry, good example on the part of the Officers who lead the well set Squadrons into the midst of an Enemy's ranks. * * * * *
