Marshal Soult, having been repulsed, retired, and the THIRTEENTH Dragoons were sent in pursuit of the enemy. The French rear-guard having been driven from _Usagre_, that post was occupied, on the night of the 24th of May, by a portion of the troops under Major-General Lumley; the THIRTEENTH being in bivouac near the town. The French advanced on the following day, when some sharp fighting occurred, in which the third dragoon guards and fourth dragoons distinguished themselves. The conduct of Colonel Head, of the THIRTEENTH Dragoons, as well as of every officer and soldier present, was commended in Major-General Lumley's despatch. The siege of _Badajoz_ having been resumed, Marshal Soult's army, strongly reinforced, again advanced; Marshal Massena's army also marched into Estremadura, and the allies again raised the siege of Badajoz, and took up a position behind the Caya, where the enemy did not venture to attack them. When the French armies retired, the Marquis of Wellington proceeded towards the Agueda, leaving the THIRTEENTH Dragoons in the Alemtejo, under Lieut.-General Hill; they were formed in brigade with the ninth dragoons and second hussars, of the King's German Legion, under Major-General Long, and were stationed at Villa Viciosa, and afterwards at Monforte, a small town nineteen miles from Portalegre. From Monforte, the THIRTEENTH Dragoons marched, towards the end of October, to the Spanish frontiers, and with other troops under Lieut.-General Hill, were engaged in the surprise of a French force under General Girard at _Arroyo de Molinos_. By forced marches, performed in stormy weather, the British arrived in the vicinity of the village at day-break on the morning of the 28th of October; a storm of rain with a thick mist concealed the advance, and the French were surprised in the act of assembling to commence their march. The cavalry marched with every precaution to avoid giving the alarm. The enemy's troops were soon broken; their artillery was captured by a squadron of the THIRTEENTH, commanded by Captain Mansell Bowers, and their infantry, attempting to escape by climbing steep mountains, were intercepted, and the greatest part made prisoners. Captain Bowers, with his troop of the THIRTEENTH, pursued a body of French cavalry, and captured a number of men and horses. The conduct of Lieutenant-Colonel Joseph Muter, who commanded the regiment on this occasion, was commended in Lieutenant-General Hill's public despatch.
