The Head Quarters of this Corps were at Liege, where was also stationed the Thirteenth Infantry Brigade; the Fourteenth Brigade was cantoned in and around Waremme; the Fifteenth Brigade at Hologne; the Sixteenth Brigade at Liers; the First Brigade of Reserve Cavalry at Tongern; the Second Brigade at Dalhem, and the Third Brigade at Lootz; the Reserve Artillery was cantoned in and about Gloms and Dalhem. Prince BLÜCHER's Head Quarters were at Namur. The points of concentration for the respective Corps were therefore Fleurus, Namur, Ciney, and Liege. The four Corps were so disposed that each could be collected at its own Head Quarters within twelve hours; and it was fully practicable to form a junction of the whole Army at any one of these points within twenty-four hours from the time of such collection. At Namur, the most central point, it would of course be accomplished in much less time. BLÜCHER had decided, in the event of an advance by the French across the line of the Sambre, by Charleroi, upon concentrating his Army in a position in front of Sombref, a point upon the high road between Namur and Nivelles, above fourteen miles from the former place, and only seven miles and a half from Quatre Bras, the point of intersection of this road with the one leading directly from Charleroi to Brussels, and at which WELLINGTON had agreed, in that case, to concentrate as large a force as time would admit, in order to check any advance in this direction, or to join BLÜCHER's Right Flank, according to circumstances. [Illustration] [Illustration] Should the Enemy advance along the left bank of the Meuse towards Namur, this place would become the point of junction of the First, Second, and Fourth Corps of the Prussian Army, whilst the Third, collecting at Ciney, would, after presenting a stout resistance at Dinant, operate as effectively as circumstances would admit, against the Right of the line of attack; and should he advance by the right bank of the Meuse towards Ciney, the Army would concentrate at this point, with the exception of the Fourth Corps, which would assemble at Liege as a Reserve, for the better security of the Left Flank and of the communications with the Rhine. * * * * * Such were the dispositions of the Allied Commanders, who contemplated no change in their arrangements until the moment should arrive of the commencement of hostile demonstrations of a decided character, for which they were perfectly prepared, and for which a vigilant look-out was maintained along the general line of the Advanced Posts.
