On the 2d of April the FOURTH marched through Guarda; on the following day they passed the Coa with their division by the bridge of _Sabugal_; and the enemy, having been previously attacked by the light division, was forced to make a precipitate retreat, and he fell back upon Alfayates. The French having retreated on Ciudad Rodrigo, the allied army stood triumphant on the confines of Portugal, from whence the KING'S OWN advanced into Spain, and were cantoned at Aldea de Bispo from the 9th of April to the beginning of May. When Marshal Massena advanced to the relief of Almeida, the allied army went into position to oppose his progress, and the fifth division taking post near Fort Conception, on the left of the line, was not attacked; the FOURTH regiment was consequently not engaged in the action at Fuentes d'Onor. After the repulse of the French army, the garrison of Almeida lost all hope of assistance, and the commandant made preparations for destroying the works, and for vacating the place. At midnight, on the 10th of May, he exploded the mines, and sallying forth in a compact column, broke through the blockading force; but was followed by a few men collected on the instant, and by the thirty-sixth regiment. Early on the following morning, as the KING'S OWN were on the march to _Barba del Puerco_, they heard the firing of musketry at a distance, and hastened towards the scene of conflict. The enemy was on the march; but the British soldiers, throwing off their knapsacks, followed at such a pace, that they overtook the rear of the column in the act of descending the deep chasm of Barba del Puerco. Many were killed and wounded, and three hundred were taken; but the remainder escaped. The KING'S OWN had two rank and file killed, and one lieutenant and ten rank and file wounded. On the 15th of June the regiment was stationed at Nava de Aver, in Portugal, where it remained three weeks, forming part of the four divisions of infantry left behind the Agueda to observe the movements of the French army under Marshal Marmont during the time the second siege of Badajoz was undertaken. When the enemy moved southwards, the regiment directed its march by Castello Branco for the Alentejo; and went into position on the Caya, being hutted near the wood and town of Aronches until the 2d of July, when it proceeded to Portalegre. While at this station the FOURTH had the misfortune to lose their commanding officer, Lieut.-Colonel Bevan, who died on the 8th of July, and was buried with military honours in the castle-yard, all the officers of the division attending. He was succeeded by Lieut.-Colonel Brooke, and brevet Lieut.-Colonel Faunce was appointed lieutenant-colonel in the regiment and placed at the head of the second battalion.
