Thus ended this eventful campaign, in which the allied army, after capturing the two important fortresses of Ciudad Rodrigo and Badajoz, gaining the glorious victory of Salamanca, and penetrating to the metropolis of Spain, was forced, by the superior number of the enemy's concentrated forces, to return to its former posts. The gigantic power to which the French revolution had given birth was, however, on the eve of being broken; Bonaparte, the tyrant of Europe, had resolved on the fatal expedition to Russia, where he lost a powerful army in the snow, and the victory at Salamanca was the precursor of greater triumphs over the disturbers of christendom. The immense distance marched by the FIFTH DRAGOON GUARDS during the year 1812, with the scarcity of forage and constant exposure to every description of weather, occasioned the loss of many horses; it has been computed that the regiment marched about two thousand miles within twelve months.
The regiment was again in motion in February, 1813, and having taken post at Viride, in the valley of the Mondego, occupied that station until the middle of April, when it proceeded to Guimarers, and halted there seventeen days.
In May the army commenced operations with a prospect of more splendid results than on any former occasion; and Colonel Ponsonby's brigade, which still consisted of the FIFTH DRAGOON GUARDS, and Third and Fourth Dragoons, traversed the wild and mountainous country of Trasos-Montes, and crossed the Esla on the 26th of May. The enemy, no longer possessing that superiority of numbers by which he had formerly gained so many advantages, abandoned the line of the Douro; Ponsonby's brigade directed its march on Valencia, passed that town, and advanced on Burgos. On the 12th of June, the brigade overtook the enemy's rear-guard on the heights of Estepar, when the Third Dragoons were detached to cut off part of the enemy's force, in which they succeeded, and Captain Miles, of the Fourteenth Dragoons, charging, took some prisoners and one gun. During the succeeding night, the French blew up the castle of Burgos, and retired behind the Ebro. Colonel Ponsonby's brigade moved to the left, and after traversing a romantic tract of country, over mountains and rugged precipices, crossed the Ebro on the 15th of June, and advanced on _Vittoria_, where the enemy concentrated his forces and took up a defensive position.
