At five on the morning of the 30th of June, he marched from Castle Nuovo, with the British and Portugueze Marines, was joined by the Russians in Naples, and proceeded instantly against St. Elmo, whose Commandant he summoned to surrender. Being answered in the negative, that zealous and spirited Officer lost no time in erecting batteries against the Castle. Between the 3d and 5th of July, nine heavy cannon and eight mortars were opened on its garrison and works, which played incessantly, in the hope of effecting a breach sufficient to storm. On the 6th, four mortars were added, and by the indefatigable labours of the Seamen, six 36-pounders were dragged to the summit of an almost inaccessible precipice, which soon compelled Monsieur Mejan to capitulate. The Marine Grenadiers marched into the Castle on the 12th, and the enemy, upwards of 1500, were allowed the honours of war. On the 13th, the main body of the army returned to Castle Nuovo, from whence they advanced against Capua, that key to Naples, upon the 19th, where they arrived on the 21st, pitched their tents near to its walls, and in a short time opened batteries, which continued to play against the town until the 27th, when terms were discussed and agreed on. On the 29th, the French, to the number of 1500, marched out, and were conveyed to Naples, under an escort of 400 Marines, and two squadrons of General Acton's Cavalry. The conduct of Captain Trowbridge was prompt and animated, and he spoke highly of the unremitting attention and discipline of Colonel Strickland, Major Creswell, the Officers and men. The exertions of those of the allied troops were also highly meritorious. Returning to Naples, an embarkation took place against Gaieta on the 30th of July, where they landed on the 3d of August, gained possession of its gates on the next day, and upon the 5th, delivered up the town to the loyal subjects of his Majesty the King of Naples. The retreat of the French armies was felt throughout Italy, and their disasters roused the Tuscans to arms, who drove them from their bosom. Florence was abandoned, and Leghorn was evacuated; but Rome was unsubdued. Its besiegers had been driven from its walls, and every effort to reduce it was ineffectual. It did not, however, resist against the tenders of British honour; for on Captain Trowbridge appearing off the mouth of the Tiber, and a summons being sent to General Garnier, he agreed to surrender Rome, Civita Vechia, and every dependency within the state, to that Commander. Some Seamen, and the Marines of the Culloden and Minotaur, occupied Corneto and Tolsa, as well as Civita Vechia, during the 29th and 30th of September, while the enemy, amounting to 5000, were sent off, agreeable to the terms of capitulation.
