On the day following their entry into Seville, Joseph and Soult directed Victor to march in pursuit of Albuquerque, and to take possession of Cadiz. So complete had been the débâcle of the Spanish armies since the Andalusian campaign began, that it seems to have been supposed that the Army of Estremadura would offer no serious resistance, even if it should succeed in throwing itself into Cadiz before it was overtaken. Marching with laudable expedition, the Duke of Belluno covered the eighty-three miles between Seville and Cadiz in four days, and presented himself in front of the place on the evening of February 5th. But Albuquerque, unmolested in his march from Utrera, had arrived on the 3rd, bringing with him not only his own troops and those of Copons, but several recruit-battalions picked up at Xeres, Lebrija, San Lucar, and Puerto Santa Maria, where they had been organizing. He had some 12,000 men in all, not counting the civic militia of Cadiz, which had hitherto been its sole garrison.
Cadiz, in the days when the practicable range of the heaviest artillery did not exceed 2,500 yards, was one of the strongest places in the world. The town lies on the extreme point of a long sandy peninsula, which runs out into the sea from the Isla de Leon, a large island separated from the mainland of Andalusia by the salt-water channel of the Rio Santi Petri, an arm of the sea varying from 300 to 400 yards in breadth, and flowing through marshes which make access to its banks very difficult. The Isla, protected by this enormous wet ditch, has a front towards the continent of about seven miles, from the naval arsenal of La Carraca at its north end to the Castle of Santi Petri at its south. Batteries had already been thrown up at all the commanding points, and Albuquerque had broken the only bridge, that of Zuazo, which crossed the marsh and the Rio. It would be impossible to pass the channel save by collecting great quantities of boats, and these would have to move under artillery fire. Venegas, the military governor of Cadiz, had already ordered all the vessels, small and great, of the villages round the bay to be destroyed or brought across to the city. Moreover, there were a score of gunboats in the channel, manned from the Spanish fleet, which could be used to oppose any attempt to cross the Rio. Indeed, naval assistance to any amount was available for the defence of Cadiz: there were a dozen Spanish and four English line-of-battle ships in the harbour. All through the three long years while the French lay in front of the Isla, no attempt was ever made to throw a force in boats across the channel: the venture seemed too hazardous.
If, however, Victor had, by some expedient, succeeded in crossing the Rio, there were two lines of defence behind it, of far greater strength than that formed by this outer ditch of the Cadiz works. The triangular Isla de Leon forms with its apex a long sand-spit, which projects for four miles into the Atlantic. Half way along it the breadth of the spit is contracted to no more than 200 yards, and here there was a continuous entrenchment from water to water, called the Cortadura, or the battery of San Fernando, armed with many heavy guns. Supposing this isthmus to have been passed, there lies, two miles further along the sand-spit, the outer enceinte of Cadiz itself, with a front of not more than 400 yards in breadth, and deep water on either side.
Cadiz had been captured more than once in earlier wars, but always by an enemy who could attack from the sea. Neither the Isla de Leon nor the San Fernando line could be held against an attack supported by a fleet which came close in shore, and battered the works from flank and rear, or landed troops behind them. The sea, it may be remarked, is four fathoms deep to within a short distance (about 300 yards) of the shore, all along the south front of the Isla and the Isthmus, so that there was nothing to prevent a fleet coming close to the works. But against any naval attack Cadiz was, in 1810, absolutely secured by the predominance of the English fleet. There was no armed French vessel nearer than Bayonne or Barcelona, nor any possibility of bringing one round. All that was done by the besiegers in a three years’ leaguer was to build some gunboats in the northern inlets of the bay, and these they never dared to bring out into the open water.
The real danger to Cadiz lay not from the sea side, nor on the Isla front, but from the inner side of the harbour and the east. Here a long spit of land runs out from beside the town of Puerto Real in the direction of Cadiz. It is called the Trocadero, from a village situated on its south-eastern side. At its extreme point is a fort named San José, while another fort, named San Luis, lies alongside of the other on a low mud-island. In advance of both, built right in the marsh, and surrounded by water at high-tide, was a third called Matagorda. These three forts were the outer defences of the harbour against a naval attack, and could cross fires with the town batteries and a castle called Puntales, which lies on the easternmost point of the isthmus, a mile from the battery of San Fernando. Matagorda is only 1,200 yards from Puntales, and 3,000 yards from the eastern point of the city of Cadiz. If the French took possession of it, and of the neighbouring San José and San Luis, they could bombard the Puntales castle and all the neighbouring section of the Isthmus, to the grave danger and discomfort of all who had to pass between the city and the Isla de Leon. They would also be able to annoy ships lying in all the eastern reaches of the great harbour. But before Victor arrived in front of Cadiz, San José, San Luis, and Matagorda were blown up, with the leave of the governor Venegas, by a detachment of seamen from the British fleet. There could, therefore, be no trouble from this direction, unless the enemy succeeded in restoring and rearming the three forts,—no easy task under the fire of the Puntales castle and the fleet. It was not till some months had passed that the struggle began for these ruined works, the only points from which the defence could be seriously incommoded.
On his first arrival Victor summoned the town, and received a prompt and angry answer of refusal from the governor and the local Junta. The marshal inspected the city’s outer defences, and was forced to report to the King at Seville that it seemed that nothing could be done against the place till he had brought up heavy artillery, and built himself boats. Joseph, unwilling to believe anything that contradicted the hopes of complete triumph that he had been nourishing ever since the passage of the Sierra Morena, came up to Puerto Santa Maria, on the bay of Cadiz, looked at the situation, did not find it reassuring, and wrote to his imperial brother to propose that he should send out his Toulon fleet to attack the place on the sea side[144]. Napoleon, still smarting under the memory of how Admiral Martin had destroyed an important section of that fleet in the preceding October, ignored this proposal. He did not forget, though his brother had apparently done so, the fact that the British Mediterranean fleet was still in existence.
Thus the position in front of Cadiz assumed the shape which it was to maintain for months, and even for years. Victor’s corps could provide enough men to observe the whole shore of the bay, and to blockade the garrison. But the Spaniards recovered their courage when they saw the enemy reduced to inactivity, and began ere long to receive reinforcements. The first to arrive were 3,000 of the regular troops which had been at Seville. This corps, under the Visconde de Gand, had escaped westward after the capitulation, and, though pursued by a brigade of Mortier’s corps, reached Ayamonte, at the mouth of the Guadiana, and there took ship for Cadiz. Somewhat later there arrived some troops sent by Wellington. The Spaniards in their day of disaster had forgotten their old jealousy about Cadiz, and asked for aid. Wellington, though loath to spare a man from Portugal, sent them in the early days of February three British[145] and two Portuguese battalions from Lisbon, under General William Stewart. So promptly were these troops shipped and landed, that they arrived at Cadiz between the 10th and the 15th of February, to the number of about 3,500 bayonets[146]. Thus the town was placed in security from any coup de main on Victor’s part.
The internal situation in Cadiz, however, left much to be desired. The town had elected a local Junta of defence, of which the governor Venegas was made President, and this body had frequent disputes with the new Regency, nominated by the Central Junta at the time of its abdication, and also with Albuquerque, whom Venegas did not wish to recognize as his hierarchical superior. The local body could make a fair show of objections to recognizing the legitimacy of the Regency: the old Central Junta itself had a doubtful origin, and the government nominated by those of its members who had taken refuge in Cadiz could not claim a clear title. But to raise the point at this moment of crisis was factious and unpatriotic, and the conduct of the local Junta became merely absurd when it tried to arrogate to itself authority extending outside its own city, and to issue orders to the outlying provinces, or the colonies of America. Still worse, it refused to issue clothing and footgear to Albuquerque’s army, whose equipment had been worn out by the long march from Estremadura, or to subsidize the military hospitals, though it had a considerable stock both of money and of military stores at its disposition. At the end of February the Regency nominated Venegas Viceroy of Mexico, and having bought him off with this splendid piece of preferment, made Albuquerque his successor in the governorship of Cadiz. But even thus they did not succeed in getting proper control over the city, for the Junta refused to allow the Duke to place his head quarters within the walls, or to issue orders to the civic militia. A modus vivendi was only reached when the Regents made an ignominious pact with the local oligarchy, by which the latter, in return for recognizing their legitimate authority, and undertaking to pay and feed the garrison, were granted the control of the port-revenues and other royal taxes of Cadiz, as well as of all the subsidies arriving from America. How the functions of government became still further complicated, when the members of the long-expected Cortes began to arrive, and to claim their rights as the sole legitimate representatives of the nation, must be told in another chapter[147].
