Shortly after the capture of Badajoz the FOURTH marched with the army towards the Agueda; on the 14th of May, the second battalion joined from Ceuta; and the brigade, consisting of the two battalions of the KING'S OWN, and second battalions of the thirtieth and forty-fourth regiments, was commanded by Major-General Pringle; Major-General Walker having returned to England in consequence of his wounds received at the storming of Badajoz. The FOURTH advanced with the army to Salamanca, and this city being rescued from the power of the enemy, exhibited a scene of tumultuous joy and rejoicing; the houses were illuminated, and the people, shouting and singing, welcomed their deliverers; while the army took up a position on the mountain of St. Christoval a few miles in advance; but the FOURTH remained behind the Tormes, and the forts which the enemy occupied at Salamanca were besieged. Marshal Marmont advancing on the 20th of June, to succour the forts, the regiment crossed the Tormes and was formed with the army in order of battle on the top of the mountain. After the capture of the forts, the enemy retired towards the Douro, and the regiment descended the heights and followed the French army, which took up a new position near Tordesillas. The KING'S OWN bivouacked in front of Tordesillas from the 2d to the 9th of July, and at Nava del Rey until the 16th; the weather being fine, the country rich, rations regularly supplied, and wine abundant, the soldiers fared luxuriously; but the enemy having passed the Douro and the Trabancos, turned the left of the allies, and marched on the 18th of July towards the Guarena, when the British retired. The two armies directing their march towards the Guarena as to one common goal, and important results depending on which should first pass the stream, a strife of speed arose. Several of the hostile columns, proceeding in parallel lines a distance of ten miles, within musket-shot of each other, marched impetuously towards the stream in perfect order, while clouds of dust arose, and a most interesting spectacle presented itself; for the officers on each side, being strangers alike to malice and to fear, were seen pointing with their swords, touching their caps, or waving their hands in courtesy as they urged their course towards the river. The British gained the stream first; the soldiers being tormented with thirst, many of them drank as they marched, and others halting in the river a few moments, were saluted with a shower of bullets; but they passed on, and the French marshal's designs were frustrated. He, however, passed the river on the 20th of July higher up, turned the right flank of the allied army, and gained a new range of hills; when Lord Wellington made a corresponding movement, and an evolution similar to that on the 18th was repeated, and it ended in the British resuming their position on the heights of St. Christoval.
