For more than twenty years the British flag flew unmolested from the “Rock.” But, in 1727, Spain made a more determined attempt to regain her lost possession. The strength of the fortress had been increased since the previous siege, but the armament was indifferent, many of the guns being so honeycombed as to be liable to burst on the first fire, and at least a hundred of them were so destroyed during the coming siege. But the command of the sea, and the presence of Hopson’s powerful fleet, prevented stores reaching the Spanish army save by land, and reinforcements, composed of the Edinburgh Regiment, the 35th, some Engineer and Artillery officers and men, as well as, later on, another line battalion and one of the Guards, were despatched to the aid of the beleaguered fortress. So again, after a tedious four months, during which time about 3000 of the enemy and 300 of the garrison had fallen, a suspension of hostilities was agreed to, and followed by a treaty of peace.
But the last and most sustained attack upon the place was made during the years 1781–83. Great Britain had been somewhat occupied, since 1775 and before, with warlike operations on the American Continent, and needed much of her naval strength to cope with French fleets and American corsairs, let alone to protect in addition her home waters. The entry of Spain into the arena intensified her difficulties; and, as might be expected, the great dream of the new enemy was to seize the opportunity of England’s difficulty and repossess herself of the key to the Straits. There was a strong French fleet cruising off Cape Finisterre in 1779, and a Spanish one in Cadiz Bay, either of which could spare a sufficiently powerful blockading squadron without risk.
So that, by the middle of August 1779, the place was closely invested by a Spanish army at San Roque, and a fleet of four ships, five xebecs, and numerous “row-galleys” in the bay; and preparations were made for the capture of Gibraltar by a formal siege, trenches, parallels, and siege batteries being carefully and laboriously constructed.
The fortress was commanded by that gallant “Cock of the Rock,” George Augustus Elliot. His garrison consisted of the 12th, 39th, 56th, and 58th Regiments, the old 72nd, or Royal Manchester Volunteers, disbanded in 1783, three Hanoverian regiments, and a company of Engineers. The strength of the place had been greatly increased, especially on the side facing the isthmus and Spain. Powerful batteries had been erected there, and galleries with portholes for guns had been hewn out of the solid rock. It was deemed impregnable in those days. It was thought that “No power whatever can take that place, unless a plague, pestilence, or famine, or the want of ordnance, musketry, and ammunition, or some unforeseen stroke of Providence should happen.” Throughout 1779 the place was simply blockaded, and there was little firing on either side. But provisions ran short. General Elliot himself tested practically that it was just possible to exist on four ounces of rice a day! The arrival of Sir George Rodney’s fleet early in 1780, after the destruction of a Spanish squadron off Cape St. Vincent, was therefore joyfully welcomed. It reprovisioned the fortress, removed the women, children, and invalids, and strengthened the garrison by a strong battalion of Highlanders, then numbered the 73rd, but now the 71st Highland Light Infantry. But by March 1781 the stores again began to fail, and soldiers were directed to economise flour and go with unpowdered hair; and a cargo of potatoes “run” by a polacca fetched £7, 10s. 6d. a hundred-weight.
The Spanish batteries, being complete and fully armed, opened a tremendous fire. Far from discouraging the garrison, they replied to it vigorously, though inferior in number of guns, and, more than that, executed a most brilliant sortie, storming the siege works and trenches, and setting fire to all the combustible material, doing damage, it was said, to the tune of £2,000,000, and that with a loss of but four killed and twenty-five wounded.
In second line to the 12th, 39th, 72nd, 73rd, etc., who led the assault, were the 39th and 58th Regiments, commanded by General Picton, the uncle of the Peninsular hero. Finally, the continuous bombardment, broken only by the diversion effected by a British squadron conveying the 25th and 39th Regiments, culminated, on the 13th September 1782, in a desperate attack both by sea and land. Specially constructed floating batteries, the sides of which were formed of timber with wet sand between, took part in the bombardment, when some 400 guns were hurling their projectiles into Gibraltar. But it was of no avail: the vessels were disabled and many burned. From the eighty cannon, with some mortars and howitzers, which formed the artillery of the defence, more than 8000 rounds were sent in reply, and quite one-half of them were red-hot shot.
So the attempt failed, and though the fire was steadily continued, the attack was practically exhausted; and the preliminaries of peace, signed in February 1783, were welcomed by all. The famous siege had lasted three years, seven months, and twelve days. The loss suffered by the garrison amounted to 1231 men, and 205,328 shot were fired during that time.
But other regiments embarked for local or special service were also meanwhile earning naval honours for the army. The 6th Regiment showed conspicuous gallantry in the attack on Fort Monjuich at Barcelona. The 6th, 9th, 11th, 17th, 33rd, and 36th Regiments also served at Almanza in 1707, and the 6th also at Saragossa; while nothing can exceed the gallantry of the defence of the Castle of Alicante by a regiment now disbanded, when the officers refused to surrender, and drank the health of good Queen Anne in a bastion over the mine that a few minutes later blew the castle nearly in pieces!
Again, in the melancholy expedition to the Spanish Main in 1740–41, the 6th, 15th, 16th, and 36th Regiments served; and the 6th, especially, suffered so terribly from fever at Jamaica in 1742 that when it returned home it had, from this and other causes, only eighteen men left of the eight hundred who sailed from England. The expedition, including the abortive attacks on Cuba and Carthagena, was throughout conducted in such a way as to be fruitless of result, and is noteworthy as a rare event in such expeditions, for the want of cordial co-operation between the naval and military commanders.
In 1746 the Royal Scots, 15th, 28th, 30th, 39th, and 42nd were embarked under General Sinclair to destroy Port L’Orient, but beyond a feeble bombardment little was done, and the army re-embarked to make a similar abortive attempt at Quiberon Bay. Similarly, the 30th fought in the naval action of Finisterre as marines (in addition of course to those troops that had been definitely enlisted for sea service), and received the thanks of the Admiral for their general behaviour. At that time the proportion of marines embarked in vessels of war was one man per gun; a fifty-gun frigate carrying therefore fifty men.
