At this period considerable exertions were making at home, with a view to attack more effectually the Spanish possessions in South America, as well as their own coasts. A large number of men of war was assembled at Spithead, and Lord Cathcart, with six regiments of Marines, now considerably strengthened, with other forces, were encamped in the Isle of Wight, and continued in readiness for these intended services. It was not until the 26th of October that the fleet set sail from St. Helens for Jamaica, where they arrived in the month of January, 1741. The united forces which were embarked on board were Wentworth's, Harrison's, and Cavendish's regiments of Foot, with the six regiments of Marines already detailed. Unfortunately for his country, and that profession of which he was so bright an ornament, Lord Cathcart very early fell a victim to the climate, when the command devolved upon the Honourable Brigadier General Wentworth. The whole force sailed from Irish Bay, in Hispaniola, upon the 25th of February, 1741, consisting in all of one hundred and twenty-four sail, having been reinforced by two of the Marine regiments raised within the American provinces, and other levies which had been previously formed in those colonies. Upon the 4th of March, in the evening, the whole anchored in the Grand Playa, to windward of the town of Carthagena, the intended object of their attack. After the necessary arrangements, the fleet moved forward in two divisions, upon the 9th, to silence the different forts, as preparatory to the landing of the troops. After little more than one hour's cannonade, those of St. Jago and St. Philip were deserted by the enemy, when five hundred grenadiers made a descent under their walls, and took possession of them. Against the 15th, every soldier, with the tents, tools, artillery, and ordnance stores were landed, the ground was cleared, and an encampment formed. About this time, the Admiral being informed by General Wentworth that the army was much incommoded by a strong fascine battery on the opposite side of the harbour, called the Barradera side, he detached a number of boats, full of men, under the conduct of Captain Boscawen, having under him Captains Laws and Coats, of the navy. Upon no occasion was intrepidity ever more conspicuous, and that great man at this time gave an earnest of what his country might expect from him. In their approach they did not observe from its situation a small battery of five guns, but they soon remedied their error, by resolutely pushing on shore, and gaining possession, after a slight resistance. The enemy rousing a little from their surprise at the other, consisting of fifteen 24-pounders, opened their fire from two guns; but following up the same spirited course, the seamen, headed by their gallant leaders, advanced most rapidly, and carried this strong battery also.
