the arsenal, barracks for two thousand men, thirteen pieces of brass, and eighty-six of iron ordnance, five thousand small arms, three hundred barrels of powder, and abundance of other stores, were captured. The arsenal, barracks, and Fort Marine, four miles from Pont-a-Vedra, with the iron ordnance, were destroyed; the more valuable stores were removed on board the transports, and the detachment returned to Vigo. The king of Spain, being oppressed on every side, his sources exhausted, and his projects defeated, dismissed his turbulent minister and made pacific overtures. A treaty of peace was concluded before the projected expedition against Peru was undertaken, and the SIXTH were again stationed in Ireland. [Sidenote: 1720] [Sidenote: 1738] On the 9th of April, 1720, Colonel Robert Dormer was succeeded in the command of the regiment by his brother, Colonel JAMES DORMER, from the fourteenth dragoons, who was promoted in February, 1738, to the first troop of horse grenadier guards: the colonelcy appears to have remained vacant until November following, when it was conferred on Lieut.-Colonel JOHN GUISE. [Sidenote: 1739] [Sidenote: 1740] The regiment was withdrawn from Ireland in the autumn of 1739, and, after its arrival in England, another war between Great Britain and Spain having become inevitable, its establishment was augmented, and it was ordered to hold itself in readiness to proceed on foreign service. A formidable armament was prepared for the attack of the Spanish colonies in the West Indies, and the land forces were placed under the orders of General Lord Cathcart, a nobleman of approved courage and experience in war. The troops having embarked in October, 1740, sailed under the convoy of a naval force commanded by Sir Chaloner Ogle; and the colonel of the SIXTH, JOHN GUISE, was appointed to serve as brigadier-general in the expedition. This regiment did not form part of the first embarkation, but it was subsequently ordered to proceed to the West Indies to reinforce the troops employed in this enterprise. A tempest dispersed the fleet, consisting of about one hundred and seventy sail, in the bay of Biscay; but the greater part of the vessels were re-collected and proceeded on the voyage. Arriving at the neutral island of Dominica, to provide wood and water, the troops sustained the loss of their gallant leader, Lord Cathcart, who died of dysentery; and the command devolved on Brigadier-General Thomas Wentworth.
