WELLINGTON, though he had been compelled to relinquish all hope of being enabled to afford that aid to BLÜCHER which, in the morning, he had proffered to him, yet, by maintaining his ground at Quatre Bras sufficiently long to admit of the arrival of reinforcements which enabled him to obtain a brilliant victory, he completely succeeded in frustrating the grand object of NEY's movements, which had been to defeat the Anglo-Allied troops thus advancing, in detail, and also to operate upon BLÜCHER's Right Flank. The Duke's success gave ample and convincing evidence of the sagacity and foresight with which his plans had been devised and matured, as also of the soundness of those calculations by which he had for some time previously placed himself, with the confident security of a master of his art, in a posture of defence, fully prepared to meet every emergency, from whatever point, or however suddenly, the coming storm might arise. And now that he had gained the Battle, and secured the important point of Quatre Bras, upon which the remainder of his troops were advancing, and where the greater portion of them would arrive in the evening and during the night, he was perfectly ready and willing, should the Prussians prove victorious at Ligny, to renew the contest on the following morning, by attacking NEY with his collected force; and then, if successful (of which little doubt could be entertained), by a junction with BLÜCHER's Right, to operate upon NAPOLEON's Left, so as to bring the great mass of the combined Armies to bear directly upon the main body of the French; or, in case of a defeat of the Prussians, to make good his retreat along his principal line of operation, in such a manner, as to secure a position between Quatre Bras and Brussels, favourable for a co-operation of BLÜCHER's forces with his own, and for presenting a bold and determined stand against the further advance of the French Emperor. Orders were now forwarded for the movement of CLINTON's Division on the following morning, at daybreak, from Nivelles to Quatre Bras: and of COLVILLE's Division, at the same hour, from Enghien to Nivelles. The Reserve Artillery was directed to move at daybreak, on the following morning, to Quatre Bras, there to receive further orders; and the Tenth Infantry Brigade, under Major General Sir JOHN LAMBERT, was directed to march, at the same hour, from Assche to Genappe, there to remain until further orders. * * * * *
