* * * * * The Third general Line, forming the Grand Reserve of the whole Line of Battle, and comprising the entire force of the Imperial Guards, Cavalry and Infantry, under the command of Lieutenant General Count DROUOT, was thus formed. The Infantry of the Imperial Guard constituted the Centre of the Reserve. It consisted of four Regiments of Grenadiers, four Regiments of _Chasseurs_, two Regiments of _Tirailleurs_, and two Regiments of _Voltigeurs_; each Regiment divided into two Battalions. The 1st and 2nd Regiments of Grenadiers, and the 1st and 2nd of _Chasseurs_, formed the Old Guard, under Lieutenant General Count FRIANT; the 3rd and 4th Regiments of Grenadiers, and the 3rd and 4th of _Chasseurs_ formed the _Moyenne_, or Middle, Guard, under Lieutenant General Count MORAND; the four Regiments of _Tirailleurs_ and _Voltigeurs_ constituted the Young Guard under Lieutenant General Count DUHESME. This force was posted somewhat in advance of the Farm of Rossomme, in six Lines of four Battalions each, at a distance of twenty yards from one another, and so disposed that the Charleroi high road alone separated the two Right, from the two Left, Battalions of each Line. To each description of the Infantry of the Imperial Guard; the Old, the Middle, and the Young, Guard, two Batteries, of eight guns each, were attached. These were stationed on either Flank; and the Reserve Artillery of the Guard, consisting of twenty four guns, was posted in rear of these Lines. The Right Wing of the Third Line, or Reserve, consisted of the Light Cavalry of the Imperial Guard, commanded by Lieutenant General LEFÈBVRE DESNOUETTES, namely, the _Chasseurs_ and Lancers of the Guard. It was posted at a distance of about two hundred yards in rear of the Fourth Cavalry Corps and deployed in two Lines, the second at a distance of sixty yards in rear of the first. The two Batteries of Horse Artillery belonging to the Corps, comprising six guns each, were posted in its centre. The Left Wing of the Third Line, or Reserve, consisted of the Heavy Cavalry of the Imperial Guard, commanded by Lieutenant General Count GUYOT, namely, the Grenadiers and Dragoons of the Guard. It was stationed in rear of the Third Cavalry Corps, and deployed in two Lines, the second at a distance of sixty yards in rear of the first.
