On the same night the island of Santa Clara, situated at the entrance of the harbour, and partially enfilading the defences of the castle, was surprised and stormed by a mixed party of sailors and soldiers, and its garrison made prisoners. On the 27th, a second sortie on the whole front of the isthmus failed entirely, and the assailants were instantly driven back. The siege and working artillery had been now augmented to eighty pieces, and on the 30th the breaches were so extensively battered down, that Lord Wellington issued orders that they should be assaulted, and the next morning was named for the attempt.
In the annals of modern warfare, perhaps there is no conflict recorded which was so sanguinary and so desperate as the storming of that well-defended breach. During the blockade, every resource of military ingenuity was tried by the French governor, and the failure of the first assault, with the subsequent raising of the siege, emboldened the garrison, and rendered them the more confident of holding out until Soult could advance and succour them. The time from which the battering guns had been withdrawn, until they had been again placed in battery, was assiduously employed in constructing new defences and strengthening the old ones. But though the place when reinvested was more formidable than before, the besiegers appeared only the more determined to reduce it.
Morning broke gloomily, an intense mist obscured every object, and the work of slaughter was for a time delayed. At nine the sea-breeze cleared away the fog; the sun shone gloriously out, and in two hours the forlorn hope issued from the trenches. The columns succeeded, and every gun from the fortress that could bear, opened on them with shot and shells. The appearance of the breach was perfectly delusive; nothing living could reach the summit; no courage, however desperate, could overcome the difficulties, for they were alike unexpected and insurmountable. In vain the officers rushed forward, and devotedly were they followed by their men. From intrenched houses behind the breach, the traverses, and the ramparts of the curtain, a withering discharge of musketry was poured on the assailants, while the Mirador and Prince batteries swept the approaches with their guns. To survive this concentrated fire was impossible; the forlorn hope were cut off to a man, and the heads of the columns annihilated. At last the debouches were choked with the dead and wounded, and a further passage to the breach rendered impracticable from the heap of corpses that were piled upon each other.
Then, in that desperate moment, when hope might have been supposed to be over, an expedient unparalleled in the records of war was resorted to. The British batteries opened on the curtain, and the storming parties heard with, surprise the roar of cannon in the rear, while, but a few feet above their heads, their iron shower hissed horribly, and swept away the enemy and their defences.
This was the moment for a fresh effort. Another brigade was moved forward, and, favoured by an accidental explosion upon the curtain, which confused the enemy while it encouraged the assailants, the terre-plain was mounted, and the French driven from the works. A long and obstinate resistance was continued in the streets, which were in many places barricaded, but by five in the evening opposition had ceased, and the town was in the possession of the British. Seven hundred of the garrison were prisoners, and the remainder were either disabled in the assault or shut up in the castle.
The town presented a dreadful spectacle, both of the work of war and of the wickedness which in war is let loose.
It had caught fire during the assault, owing to the quantity of combustibles of all kinds which were scattered about. The French rolled their shells into it from the castle, and while it was in flames the troops were plundering, and the people of the surrounding country flocking to profit by the spoils of their countrymen. The few inhabitants who were to be seen seemed stupefied with horror; they had suffered so much that they looked with apathy at all around them, and when the crash of a falling house made the captors run, they scarcely moved. Heaps of dead were lying everywhere—British, Portuguese, and French, one upon another; with such determination had the one side attacked and the other maintained its ground.
Very many of the assailants lay dead on the roofs of the houses which adjoined the breach. The bodies were thrown into the mines and other excavations, and there covered over so as to be out of sight, but so hastily and so slightly, that the air far and near was tainted, and fires were kindled in the breaches to consume those which could not be otherwise disposed of.
The hospital presented a more dreadful scene, for it was a scene of human suffering; friend and enemy had been indiscriminately carried thither, and were there alike neglected. On the third day after the assault, many of them had received neither surgical assistance nor food of any kind, and it became necessary to remove them on the fifth, as the flames approached the building. Much of this neglect would have been unavoidable, even if that humane and conscientious diligence which can be hoped for from so few, had been found in every individual belonging to the medical department, the number of the wounded being so great; and little help could be received from the other part of the army, because it had been engaged in action on the same day.
The unfortunate town seemed alike devoted by friends and enemies to destruction. The conquerors were roaming through the streets, the castle firing on the houses beneath its guns, in many places fire had broken out, and a storm of thunder, rain, and lightning added to the confusion of a scene which even in warfare finds no parallel.
