Upon the exterior slope of that portion of the ridge which lies between the before mentioned Knoll and the Genappe high road, BYLANDT's Brigade of PERPONCHER's Division of the troops of the Netherlands was deployed in Front Line. It consisted of the 27th Battalion of Dutch Light Infantry, the 7th Battalion of the Belgian Line, and of the 5th, 7th, and 8th Battalions of Dutch Militia. Of the above, the 5th Battalion of Dutch Militia was posted in reserve, along with the remaining four guns of Captain BYLEVELD's Battery of Horse Artillery attached to this Brigade, in rear of the straggling hedge which lines the Wavre road, between the Knoll and the Charleroi high road. Upon the interior slope of the ridge, and at a distance of about two hundred yards from the Wavre road, was posted the Ninth Brigade of British Infantry, under Major General Sir DENIS PACK, in a Line of Battalion Columns, at deploying intervals. It consisted of the 3rd Battalion 1st Royal Regiment, the 1st Battalion 42nd Royal Highlanders, 2nd Battalion 44th Regiment, and of the 92nd Highlanders. The Left Regiment, the 44th, was stationed on the Knoll, in rear of the Right of BEST's Hanoverian Brigade; and on the right of the 44th stood, in succession, the 92nd, 42nd, and 1st Royals. Upon the right, but more in advance, of PACK's Brigade, and at a short distance in rear of the hedge along the Wavre road, stood the Eighth Brigade of British Infantry, under Major General Sir JAMES KEMPT, also in Line of Battalion Columns, at deploying intervals, and comprising the 28th Regiment, the 32nd Regiment, the 1st Battalion 79th Highlanders, and the 1st Battalion 95th Rifles. The Right of the 32nd Regiment rested upon a high bank of the Charleroi road; on its left stood the 79th Highlanders, and the 28th formed the Left Regiment of the Brigade. In the immediate front of the Right of the Brigade, and at a distance from the Wavre road of about 120 yards, there was a Knoll having on its right a large Sand Pit, adjoining the Charleroi road; and partially facing the small Garden in rear of La Haye Sainte. On the Allied side of the Knoll was a single hedge, extending about 150 yards from the Charleroi road in a direction parallel to the Wavre road. In the Sand Pit were posted two Companies of the 1st Battalion 95th British Rifles; the Knoll and hedge were occupied by another Company of the same Regiment. These Advanced Companies had placed an _abatis_ across the high road, near that part of it which is joined by the hedgerow. The remaining Companies lined a portion of the Wavre road, commencing from the point of its intersection with the Charleroi road. These two Brigades, namely, the Eighth and Ninth British, together with the Fifth Hanoverian Brigade, constituted the Fifth Division, under Lieutenant General Sir THOMAS PICTON. * * * * *
