The division proceeded on the 21st of March from Almendralejos to Merida, and on the 26th advanced towards Medellin and Don Benito, from which places it forced the enemy to retire. Advices were here received, that the enemy, under Marshal Soult, was advancing to Llerena, with a view to relieve Badajoz, to the vicinity of which place the covering army was directed to retire. On the 31st of March, the division proceeded towards Merida, where it arrived on the 2nd of April; it marched on the 5th to a position near Talavera Real. On the night of the 6th of April, Badajoz was assaulted and carried by the troops under the Earl of Wellington, Marshal Soult consequently retraced his steps towards Seville. The battalion marched into quarters in Almendralejos on the 13th of April. A French force having made an irruption into the province of Beira, the Earl of Wellington, with the main body of the army, crossed the Tagus immediately after the fall of Badajoz. On the 12th of May, the battalion marched from Almendralejos, and bivouacked near Merida; on the 13th near Arroyo-del-Molinos; on the 14th near Villa Mesias; on the 15th entered Truxillo, and marched again about midnight; on the 16th bivouacked near Jaraicejo, and on the following day proceeded to the mountains near Casas del Puerto. On the 18th of May, the NINETY-SECOND marched at night to attack the enemy’s fortifications covering the bridge of _Almaraz_. The ruggedness of the footpath through the mountains, and the darkness of the night, presented serious obstacles to a rapid march; it was consequently daylight before the troops were formed in the Valle de Canas. The fiftieth regiment and a wing of the seventy-first were formed in one column, and were destined to assault Fort Napoleon on the 19th of May; while the NINETY-SECOND under Lieut.-Colonel Cameron, and the other wing of the seventy-first, were formed in a second column, ready to support the attack on Fort Napoleon, or to carry the _tête-de-pont_ at the same moment, both columns being provided with scaling ladders. Fort Napoleon was carried in gallant style by the column sent against it, the enemy flying from it towards the _tête-de-pont_; the NINETY-SECOND dashed forward and entered with him. The commandant of Fort Ragusa, on the opposite bank of the Tagus, being seized with a panic, had cut away the bridge of boats; many of his countrymen consequently were either drowned or made prisoners. The attention of all was now directed to the passage of the river. Some of the NINETY-SECOND immediately leaped in, and swam to the opposite side, bringing the boats back with them.[14] Thus was the bridge secured, together with Fort Ragusa, which the enemy immediately abandoned.
