'Pushing forward with a strength equal to their animation, they soon climbed the entrenchments, and entering the embrasures in the face of a continued fire, and on the very muzzles of the guns, they drove the enemy from the works with considerable slaughter; and after spiking the cannon and burning the platforms, together with the gun-carriages, guard-house, and magazine, Boscawen led off his detachment in order, and returned to the fleet with six wounded prisoners. The Spaniards, fully sensible of the support which this battery had afforded them, were indefatigable in their endeavours to repair it; and having in a few days so far succeeded as to be able to bring six guns to bear upon the English fleet, Boscawen was again ordered to reduce it, but in a manner which exposed him less to personal danger than in the service in which it was before deemed expedient to employ him. He was directed to proceed with his own ship, the _Shoreham_, together with the _Princess Amelia_ and the _Lichfield_, as close inshore as the depth of the water would admit them (a dangerous enterprise in consequence of the difficulties of the navigation here), to anchor abreast of the battery, and to bring the ships' broadsides to bear upon it; whilst, on the other hand, a detachment of seamen, under the command of Captains Watson, Cotes, and Dennis, were at the same time to storm it. These measures, taken with so much skill and prudence, would in all probability have ensured the success of the attack; but the Spaniards, intimidated by the formidable appearance of the assailants, _abandoned the battery without firing a shot_.' But the place was too strongly fortified; and the siege of Carthagena was soon after raised (a circumstance which, by the way, tended to hasten the fall of Walpole). Yet before Boscawen left he was again employed, as at Porto Bello, to rase the different forts which the English had taken on the neighbouring coast; and, whilst engaged on this service, was appointed to the _Prince Frederick_, of 70 guns, on the death of Lord Aubrey Beauclerk, who gallantly fell at Boca Chica. Clinton observes that the siege lasted from January to 24th April, 1741; and that as the surf prevented a bombardment from the sea, it was determined to make a lodging on Boca Chica, in order to reduce the fort there. The long-standing jealousy between the navy and the army was, he thinks, the cause of the failure of the siege. However that may be, three thousand men were lost by assaults and sickness; and the fleet returned to Jamaica.
