Lieut.-Colonel Southwell, of the Sixth foot, to commence the attack with the grenadiers; this service was performed with signal intrepidity and resolution. Upon this success the Prince of Hesse Darmstadt advanced to possess himself of a post which would prevent the enemy’s communication with the town, and in the attempt was mortally wounded. The loss of this officer damped the spirits of the soldiers;--the enemy, perceiving some disorder amongst the Confederates, called out, “Long live King Charles!” and invited the assailants to come to them; upon Colonel Allen’s advance to the fort, with about two hundred and fifty men, the Spaniards opened the gate the better to conceal their stratagem, but immediately fired upon the men, and compelled this detachment to surrender; at the same time, a large reinforcement was seen advancing from the town to aid the garrison in the castle, whereupon the troops were seized with a panic, and Lord Charlemont, with other officers, endeavoured to counteract the disorder which ensued. Upon the Earl of Peterborough receiving this intelligence, his lordship placed himself at the head of the detachments that were retreating,--rallied them, and ultimately regained the posts they had before so nobly acquired; the Spaniards who were advancing from the town retired, and the outworks of _Montjuich_ were gained. Batteries were then constructed, and the inner works were assailed with cannon balls, bombs, and grenades. After the action was over, the Earl of Peterborough introduced Lord Charlemont and Lieut.-Colonel Southwell to the King of Spain, as officers that had done His Majesty signal service on this occasion; for which they both received the thanks of that Prince.[6] On the 17th of September, Lieut.-Colonel Southwell, of the Sixth regiment of foot, being on duty in the trenches, observed that the bombs thrown by a Dutch bombardier from a small mortar fell to the left of the fort, and concluding that there was a magazine in the place, he traversed the mortar himself more to the right, and fired it; the bomb fell into a small chapel where the garrison had stored their powder, which exploded, and buried a number of officers and men in the ruins. Lieut.-Colonel Southwell advanced at the head of his men, and was met by the surviving officers and men of the garrison, who immediately surrendered the fortress. The Lieut.-Colonel was made Governor of the place, in consideration of his services.
