Along that portion of the Hougomont Avenue which is nearest to the Nivelles road was extended the Light Company of the 23rd Regiment. On its right was an _abatis_, which had been thrown across the great road; and close upon the right of this artificial obstacle, a Company of the 51st Regiment was posted. Four more Companies of this Regiment, and the Light Company of the 14th, were extended along the hollow way alluded to as stretching across the ridge, on the extreme Left of the French position. The remainder of the 51st stood in Column of Support, about two hundred yards in rear of the hollow way. The 23rd Regiment was stationed on the left of the Nivelles road, on the reverse slope, and immediately under the crest of the main ridge, in rear of the Second Brigade of Guards. The 14th Regiment was posted in Column on the southern descent from the plateau, on which was assembled the Second British Division; and from the view which it possessed of the ground occupied by the 51st, it was well placed as a Reserve to the Light Infantry. In a ravine, descending from the immediate Right of the Skirmishers of the Brigade down into the valley, was posted a Squadron of the 15th British Hussars (under Captain WODEHOUSE), from which a Picquet was detached to the right of the _abatis_, as also an intermediate one for keeping up the communication; and some Vedettes were thrown out to the right, having in their front a continuation of the ravine, possessing a more marked and distinct character. * * * * * The troops posted upon the plateau already described as situated on the west of the Nivelles road and in front of the Village of Merbe Braine, and which, together with Colonel MITCHELL's Brigade, constituted the extreme Right of the Anglo-Allied Army, under the command of Lord Hill, were available either as a Reserve to the main Line of Battle, or as a defence against any hostile attempt upon the Right Flank. They consisted of the main body of the Second Infantry Division, commanded by Lieutenant General Sir HENRY CLINTON. This was composed of the Third British Light Brigade, under Major General Sir FREDERICK ADAM; of the First Brigade of the King's German Legion, under Colonel DU PLAT; and of the Third Hanoverian Brigade, under Colonel HALKETT.
