Commencing from the right, near to the Nivelles road, stood the Fifth Brigade, under Major General Sir Colquhoun Grant, consisting of the 7th and 15th Hussars, and of the 13th Light Dragoons (under Colonel Doherty.)
On the left of Grant's Brigade was posted the Third Brigade under Major General Sir William Dörnberg, consisting of the 23rd Light Dragoons, and of the 1st and 2nd Light Dragoons of the King's German Legion. The Cumberland Hanoverian Hussars (under Lieutenant Colonel Hake) were attached to, and formed in rear of, this Brigade. They properly belonged to Colonel Estorff's Hanoverian Cavalry Brigade: as did also the Prince Regent's Hussars (under Lieutenant Colonel Ferdinand Count Kielmansegge), and the Bremen and Verden Hussars (under Colonel August von dem Bussche); which Regiments were detached with the force at Hal.
Still more to the left, and in rear of the Right of Alten's Division, stood the 3rd Hussars of the King's German Legion, under Colonel Sir Frederick von Arentsschildt.
Immediately on the right of the Charleroi road, and in rear of Alten's Division, the First or Household Brigade, under Major General Lord Edward Somerset, was drawn up. It comprised the 1st and 2nd Life Guards, the Royal Horse Guards (Blue), and the 1st Dragoon Guards.
On the left of the Charleroi road, and in rear of Picton's Division, stood the Second Brigade, under Major General Sir William Ponsonby; consisting of the 1st Dragoons (Royals), the 2nd Dragoons (Scots Greys), and the 6th Dragoons (Inniskillings).
The Fourth and Sixth Brigades, under Major Generals Sir John Vandeleur and Sir Hussey Vivian, were posted upon the extreme Left of the main Line of the position, as previously explained.
The Reserves consisted of the Dutch-Belgian Cavalry Division, under Lieutenant General Baron Collaert; of the Brunswick Corps, comprising both Cavalry and Infantry, the command of which, since the fall of the Duke, had devolved upon Colonel Olfermann; and of the Tenth British Brigade, under Major General Sir John Lambert. The latter formed part of the Sixth Division, commanded by Lieutenant General the Hon. Sir Lowry Cole; and had only just reached the Field, after having performed forced marches from Ghent.
Collaert's Division was stationed in rear of the Centre, and within the angle formed by the junction of the high roads leading from Charleroi and Nivelles. It comprised the First Brigade, commanded by Major General Trip, and consisting of the 1st Dutch Carabiniers, the 2nd Belgian Carabiniers, and the 3rd Dutch Carabiniers; the Second Brigade, commanded by Major General Ghigny, and consisting of the 4th Dutch Dragoons, and the 8th Belgian Hussars; and the Third Brigade, commanded by Major General van Merlen, and consisting of the 5th Belgian Light Dragoons, and the 6th Dutch Hussars.
