"I request you will say to the Duke of WELLINGTON, in my name, that even ill as I am, I shall, nevertheless, put myself at the head of my troops, for the purpose of immediately attacking the Enemy's Right Flank, should NAPOLEON undertake anything against the Duke. If, however, the day should pass over without a hostile attack, it is my opinion that we ought tomorrow, with our combined forces, to attack the French Army. I commission you to communicate this as the result of my inward conviction, and to represent to him that I consider this proposal to be the best and most suitable in our present position. "BLÜCHER." The Prussians very soon discovered that the French had made no disposition whatever for the protection of their Right Flank. Major WITOWSKY had proceeded as far as Maransart before he fell in with an Enemy's Patrol; and Major FALKENHAUSEN found the Defiles of the Lasne perfectly free and unobserved. Upon receiving this intelligence, BLÜCHER decided upon supporting the Anglo-Allied Army, by directing the march of his whole force, or at least of three Corps, towards the Wood of Paris, and debouching from thence upon the Flank and Rear of the Enemy; and Major LÜTZOW was immediately despatched for the purpose of narrowly watching, from the other side of the above Wood, the French movements directed against the position of the Anglo-Allied Army. No report as yet had been received from the Rear Guard, concerning GROUCHY's advance, and as BLÜCHER's object was now to gain the Defiles of the Lasne without interruption, and to occupy in force the Wood of Paris, he determined to avail himself of the time and opportunity which offered for the projected movement. Being, however, uncertain as to the amount of GROUCHY's force, the Prince deemed it advisable that Wavre should not be abandoned until the greater part of the Army had passed the Defiles of St Lambert; and with this view, he directed that as soon as BÜLOW's Corps should have proceeded beyond Wavre, ZIETEN's Corps was to commence its march by Fromont and Ohain to join the Left Wing of WELLINGTON's Army near La Haye. PIRCH's Corps was ordered to follow BÜLOW's in the direction of St Lambert; and THIELEMANN's Corps, after retaining possession of the Defile of Wavre sufficiently long to render the general movement of the Army secure, was then gradually to follow ZIETEN's Corps upon Ohain.
