For this purpose, ten large ships, from 600 to 1400 tons burden, had been cut-down, and 200,000 cubic feet of timber worked in their construction. To protect them from bombs, and the men at the batteries from grape, or descending shot, a hanging roof was contrived; which was worked up and down by springs. The roof was composed of a strong rope-work netting, laid over with a thick covering of wet hides, while its sloping position was calculated to prevent shells from lodging, and to throw them off into the sea before they could burst. To render the fire of these batteries the more rapid, a kind of match had been contrived, so to be placed that all the guns in the battery could go off at the same instant. To defend them from red-hot shot, with which the fortress was supplied, the newest part of the plan was that by which water could be carried in every direction to neutralise its effect. In imitation of the circulation of the blood, a variety of pipes and canals perforated all the solid workmanship in such a manner that a continued succession of water could be conveyed to every part of the structure, a number of pumps being adapted to afford an unlimited supply. It was thus believed that these terrible machines, capable of inflicting destruction, would themselves be invulnerable. The largest carried 21 guns, and their complement of men was 36 for each gun in use, exclusive of officers and mariners for working the ships.

General Elliot, undaunted by the preparations made by the enemy, determined to try what he and his brave garrison could do to counteract them. Accordingly, at seven o’clock in the morning of the 8th of September, he opened a tremendous fire on their works with red-hot shot, carcasses, and shells. At ten o’clock the Mahon battery, with the one adjoining it, were in flames. By five in the evening both were entirely consumed; a great part of the eastern parallel, and of the trenches and parapet for musketry, were likewise destroyed. A large battery near the bay was so much damaged by having repeatedly been set on fire, that the enemy were compelled to abandon it, while they lost an immense number of men in their endeavour to extinguish the flames. The next day the French and Spaniards opened a new battery of 64 heavy cannon, which, with the artillery from the lines and mortars, continued to play upon the garrison without intermission the whole day. At the same time, seven Spanish ships of the line and two French, with some frigates and small vessels, passing along the works discharged their broadsides, until they had passed Europa Point, and got into the Mediterranean.

In the meantime, the English squadron being too small to compete with them, the seamen had been landed, under the command of Captain Roger Curtis, and had been placed in the batteries at Europa Point. Hence they had attacked the Spanish line-of-battle ships, and compelled them to haul off.

About eight o’clock in the morning of the 13th of September, the battering ships lying at the head of the bay, under the command of Rear-Admiral Don Moreno, got under sail to attack the fort. At ten o’clock the admiral having taken up his station off the king’s bastion, the other ships extended themselves at moderate distances from the old to the new mole, in a line parallel with the rock, at a distance of about one thousand yards, and immediately commenced a heavy cannonade, supported by the cannon and mortars on the enemy’s lines. On seeing this the garrison opened a tremendous fire; the red-hot shot were thrown with such precision that about two o’clock in the afternoon, the smoke was seen to issue from the admiral and another ship, the men in vain endeavouring to extinguish the fire by pouring water into the holes. By one o’clock the two ships were in flames, and seven more took fire in succession. Signals of distress were now seen flying on board the Spanish ships, while the launches came up for the purpose of taking the men out of the burning ships, it being impossible to remove them. When he saw this, Captain Curtis advanced with his gunboats and drew them up so as to flank the enemy’s battering ships, which were annoyed by an incessant, heavy, and well-directed fire from the garrison. The Spanish boats were so assailed by showers of shot and shell that they would not venture on a nearer approach, and were compelled to abandon their ships and friends to the flames. Several of the enemy’s boats were sunk; the crew of one of these were all drowned, with the exception of an officer and twelve men, who floated on the wreck under the walls, and were rescued by the English.

The scene was full of horrors. Numbers of men were observed in the midst of the flames, imploring relief; others were seen floating on pieces of timber; while even those on board the ships not on fire expressed the deepest distress, and were equally urgent in asking for assistance. Captain Curtis and his gallant sailors, though exposed to the greatest possible danger, eagerly boarded the burning ships to rescue the now conquered enemy from destruction. While they were thus engaged, one of the largest of the Spanish ships blew up, spreading its wreck far around. By this accident, one English gunboat was sunk, and another much damaged. A piece of falling timber struck a hole through the bottom of Captain Curtis’ barge, by which his coxswain was killed and two of his crew wounded; the rest were saved from perishing by the seamen stuffing their jackets into the hole, which kept the boat afloat until others came to their assistance. While the ships were burning, numbers of Spaniards were seen floating on pieces of timber, liable every moment to be washed off, or destroyed by the shot from the garrison. As soon, however, as it was discovered that the enemy were defeated, the firing from Gibraltar entirely ceased, and every possible effort was made to save the Spaniards from death. Nine of these formidable batteries were burnt by the red-hot shot, and the tenth was set on fire by her crew, as it was found impracticable to carry her off. Even had the battering ships not taken fire, the Spaniards would have had no chance of success, as the works of the fortress, notwithstanding the tremendous fire directed against them, were scarcely damaged. During the nine weeks the siege had been going on, only 65 of the garrison had been killed, and less than 400 wounded, while the seamen had only lost two or three men.

A heavy gale coming on, several of the French and Spanish ships suffered material damage, and the Saint Michael, a 72-gun ship, carrying 650 men, was driven close under the works, and struck after a few shot had been fired into her. She was got off by Captain Curtis a few days afterwards, with the loss only of her mizen-mast.

On the 11th of October Lord Howe appeared with a large fleet, which the enemy endeavoured to avoid. After seeing the troop-ships which he had convoyed into the harbour, he went in search of the enemy’s fleet, which, after a short engagement, hauled their wind and stood off to the north-west.

In the bomb-proof vessels above described we recognise the idea of our present floating batteries; while the result of their attack on Gibraltar might have shown our naval commanders in the Crimean war the slight hope there was of any advantage being gained by their attack on the batteries of Sebastopol.

The great object of the French was to capture the island of Jamaica. For this purpose, the Comte de Grasse, who commanded their fleet in the West Indies, was using every exertion to equip his fleet and to form a junction with the Spaniards. Sir George Rodney, with Sir Samuel Hood and Admiral Drake and Commodore Affleck under him, were on the look-out to prevent them. At length, on the 8th of April, while the English fleet was at anchor at Saint Lucia, Captain Byron, in the Andromache frigate, communicated to the admiral by signal that the enemy’s fleet, with a large convoy, were seen coming out of Fort Royal Bay, and standing to the north-west. Sir George instantly made the signal to weigh, and on the morning of the 9th the enemy were seen forming a line of battle to windward, and standing over towards Guadaloupe. For some time the British fleet was becalmed, but as the breeze reached the van division, commanded by Sir Samuel Hood, he stood on and closed with the enemy’s centre. At nine o’clock the action commenced, and was maintained with determined bravery for upwards of an hour by this division, the Barfleur having generally three ships firing upon her at once. At length the leading ships of the centre got the breeze, and were enabled to come up to the assistance of the van. These were soon after followed by the Formidable, Bake, and Namur. The action raged it for some time, much gallantry being displayed by the captain of a French 74-gun ship, who, backing his main-topsail, steadily received and returned the fire of these three ships in succession. The Comte de Grasse, seeing the remainder of the British fleet coming up, withdrew out of fire, and by the 11th his fleet was nearly hull down. All hopes of being able to keep up with them appeared to be at an end, when two French ships, which had been much damaged, were perceived about noon to leeward of their fleet. Chase was instantly made by the English, when the Comte de Grasse bore down to their relief. Sir George Rodney on this recalled the ships in chase, and formed a close line of battle, carrying sail to windward all night. At dawn of the 12th, a French ship of the line, the Zélé, 74 guns, was seen much disabled, and towed by a frigate. The Comte de Grasse, on perceiving that she must be taken, bore up with his whole fleet for her protection. He could now no longer avoid an engagement. At half-past seven Rear-Admiral Drake’s division, which led, commenced the action, which soon became general from van to rear. Captain Gardner, in the Duke, having unsuccessfully attempted to force the enemy’s line, in consequence of the loss of his main-topmast, Sir George Rodney, in the Formidable, supported by the Namur and Canada, broke through their line, about three ships from the Ville de Paris, and was followed by the ships in his rear, when he wore and doubled upon the enemy. By this manoeuvre the French line was broken and thrown into the utmost confusion; their van bore away, and endeavoured to re-form to leeward, but this, hardly pressed as they were, they were unable to accomplish. Sir Samuel Hood’s division, which had been becalmed the greater part of the forenoon, now coming up, completed the victory. Several of the French ships struck. Captain Cornwallis, to whom the Hector had yielded, left his prize, and made sail after the French admiral in the Ville de Paris. The well-directed fire of the Canada so much annoyed her, and some other ships approaching, made it impossible for her to escape; but the Comte de Grasse seemed determined to sink rather than yield to anything under a flag. At length Sir Samuel Hood came up in the Barfleur, and poured in a tremendous and destructive fire. The brave Frenchman maintained the action for a quarter-of-an-hour longer, when finding further resistance vain, and that he was deserted by his second, hauled down his flag. The enemy’s fleet continued going off before the wind in small detached squadrons and single ships, pursued by the British. On this, Sir George made the signal to bring to, in order to collect his fleet and secure the prizes. Some of the ships, however, not observing the signal, did not return till the next day. Before the prisoners could be shifted from the Caesar, she caught fire and blew up, an English lieutenant and 50 men belonging to the Centaur, together with 400 Frenchmen, perishing.

The French are supposed to have lost 3000 men killed, and double that number wounded, for, besides the ships’ crews, the fleet had on board 5500 troops. It was said that at the time the Ville de Paris struck there were but three men left alive and unhurt on the upper deck, and that the Comte de Grasse was one of the three.
