On the 31st of May, 1813, the battalion proceeded with the army, under Lieut.-General Sir John Murray, intended for the reduction of _Tarragona_, and on arrival formed part of the force detached under Lieut.-Colonel Prevost, of the SIXTY-SEVENTH, for the purpose of investing the fort of _San Philippe_, in the Col de Balaguer, which blocks the direct road from Tortosa to Tarragona. The fort of San Philippe is situated upon the eastern extremity of an insulated village, in the centre of the Col de Balaguer, commanding completely the great road through the pass. It was a square fort with some bastions, and commanded on two sides by almost inaccessible mountains. Lieut.-Colonel Prevost and the brigade under his command, consisting of the second battalion of the SIXTY-SEVENTH, the battalion of Roll Dillon, and a detachment of royal artillery, landed, about eleven o'clock in the forenoon of the 3rd of June, about one mile to the eastward of the entrance to the pass from Tarragona, where he was joined by the Spanish regiments of Barcelona and Palma, under the command of Don Jose Charles. On the 3rd of June the fort was invested, and on the day following a summons was sent to the commanding officer to surrender, offering favourable terms, which were, however, rejected. On the 5th of June the batteries continued a heavy fire upon the fort, which was returned by the enemy, who kept up a heavy and galling fire of shells, round and grapeshot, during the whole of the night, which occasioned some loss. About ten o'clock a most violent storm of thunder and lightning commenced, which impeded the works greatly, and as the seamen and troops were quite exhausted, it became expedient to delay bringing the guns upon the platforms, and to keep the embrasures masked. In the evening of the 6th of June a battery of two eight-inch mortars was placed upon the road, within a few hundred yards of the Castle, under the breaching battery; one four-pounder was likewise placed upon the heights to the right, where the riflemen were stationed. At daybreak on the 7th, three batteries opened to protect the working party at the breaching battery, and kept up a tremendous fire until six o'clock, when that of the Castle having ceased, their magazines upon the batteries having been blown up by the shells from the mortars, the white flag was hoisted upon the Castle, and the garrison offered to surrender upon conditions of marching out and grounding their arms upon the glacis, with permission to carry off the personal baggage, which terms were granted, as Marshal Suchet's approach was hourly expected, and Lieutenant-Colonel Prevost would be enabled to put the fort in a good state of defence. Possession was taken of the Castle on the 7th of June. Lieutenant-General Sir John Murray, in his despatch to the Marquis of Wellington, stated--
