The recent fall of the French occupied fortress city of Badajoz, on 6 April 1812, allowed the Anglo-Portuguese forces under Wellington to take the strategic offensive.
Prior to moving the bulk of his forces north where he would launch his Salamanca campaign Wellington entrusted a considerable proportion of his available cavalry to a force under General Sir Rowland Hill who was ordered to drive the retreating French army of Marshal Soult, who had failed in his attempt to relieve Badajoz, back into Andalusia to the south.
Hill's cavalry, under Sir Stapleton Cotton, were indeed pressing those French forces still remaining in the province of Extremadura hard.
The French cavalry force, attached to D'Erlon's two infantry divisions, commanded by General François "Charles" Lallemand was composed of the 2nd Hussars and the 17th and 27th Dragoons.
During the night he despatched Ponsonby with the 12th and 14th Light Dragoons to probe the Villagarcia area, whilst Le Marchant was sent on a circuitous march to get on the French left flank and, it was hoped, cut off their retreat.
Coming down from rugged hills bordering the plain where the action was fought Le Marchant and the 5th Dragoon Guards had pulled considerably ahead of the other two regiments of the brigade.
[6] Lallemand, it is recorded, caught a glimpse of red-coated figures in the woods to his left and rode to alert General Peyremmont, who was leading the 2nd Hussars.
[8] The British pursuit, continuing to inflict casualties and take prisoners, was conducted all the way back to the walls of Llerena where the bulk of D'Erlon's force was concentrated.
