The disposition of the French Left Column, under NEY, during the night of the 15th, has already been shown. The Centre Column of the French Army was thus located--VANDAMME's Corps bivouacked in the Wood of Fleurus; PAJOL's Corps of Light Cavalry at Lambusart; the Third Light Cavalry Division, under DOMON, on the left, at the outlet of the Wood, and the Heavy Cavalry Corps of EXCELMANS between the Light Cavalry and VANDAMME; the Guards bivouacked between Charleroi and Gilly; and LOBAU's Corps, together with MILHAUD's Heavy Cavalry Corps, lay in rear of Charleroi. The Right Column, consisting of GÉRARD's Corps, bivouacked in front of the Bridge of Châtelet, which point it had reached during the evening. * * * * * The result of the proceedings on the 15th was highly favourable to NAPOLEON. He had completely effected the passage of the Sambre; he was operating with the main portion of his forces directly upon the preconcerted point of concentration of BLÜCHER's Army, and was already in the immediate front of the chosen position, before that concentration could be accomplished; he was also operating with another portion upon the high road to Brussels, and had come in contact with the Left of WELLINGTON's troops; he had also placed himself so far in advance upon this line, that even a partial junction of the forces of the Allied Commanders was already rendered a hazardous operation, without a previous retrograde movement; and he thus had it in his power to bring the principal weight of his arms against the one, whilst, with the remainder of his force, he held the other at bay. This formed the grand object of his operations on the morrow.
