On the 17th, however, Colonel Southwell by a well aimed shot brought the siege to a close. He noticed that a small chapel within the fort appeared to be specially guarded by the besieged, and ordered a Dutch sergeant of artillery, who was working a heavy mortar, to try to drop a shell upon it. The artilleryman made several attempts, but each time missed the mark. Colonel Southwell undertook the management of the mortar himself, and soon succeeded in dropping a shell upon the roof of the building, which proved, as he had suspected, to be in use as a magazine. There was a tremendous explosion, the chapel was shattered into fragments, Caraccioli and three other officers were killed, and a great breach was blown in the main rampart.
A loud cheer broke from the besiegers, and Colonel Southwell at once put himself at the head of the men in the trenches and advanced to storm the breach before the enemy could recover from their confusion. The disastrous effects of the explosion had, however, scared all idea of further resistance out of the minds of the defenders, who at once rushed out of the works and called out that they surrendered, the senior surviving officer and his companions delivering up their swords to Colonel Southwell, and begging that protection might at once be given to their soldiers from the Miquelets, whose ferocity was as notorious then as it was a hundred years afterward.
Peterborough appointed Colonel Southwell governor of Montjuich, and at once turned his attention to the city. The brilliant result of the attack on the citadel had silenced all murmurs and completely restored Lord Peterborough's authority. Soldiers and sailors vied with each other in their exertions to get the guns into position, and the Miquelets, largely increased in number, became for once orderly and active, and labored steadily in the trenches.
The main army conducted the attack from the side at which it had been originally commenced, while General Stanhope, his force considerably increased by troops from the main body, conducted the attack from the side of Montjuich. Four batteries of heavy guns and two of mortars soon opened fire upon the city, while the smaller vessels of the fleet moved close in to the shore and threw shot and shell into the town.
A breach was soon effected in the rampart, and Velasco was summoned to surrender; but he refused to do so, although his position had become almost desperate. The disaffection of the inhabitants was now openly shown. The soldiers had lost confidence and heart, and the loyalty of many of them was more than doubtful. The governor arrested many of the mutinous soldiers and hostile citizens, and turned numbers of them out of the city.
On the 3d of October the English engineers declared the breach on the side of Montjuich to be practicable, and Peterborough himself wrote to the governor offering honorable terms of capitulation, but declaring that if these were rejected he would not renew his offer.
Velasco again refused. He had erected a formidable intrenchment within the breach, and had sunk two mines beneath the ruins in readiness to blow the assailing columns into the air.
The guns again opened fire, and in a very short time a Dutch artillery officer threw two shells upon the intrenchment and almost destroyed it, while a third fell on the breach itself, and crashing through the rubbish fired Velasco's two mines and greatly enlarged the breach. The earl could now have carried the town by storm had he chosen, but with his usual magnanimity to the vanquished he again wrote to Velasco and summoned him to surrender.
The governor had now no hope of a successful resistance, and he therefore agreed to surrender in four days should no relief arrive. The terms agreed upon were that the garrison should march out with all the honors of war, and should be transported by sea to San Felix, and escorted thence to Gerona; but as a few hours later the news arrived that Gerona had declared for King Charles, Velasco requested to be conveyed to Rosas instead. The capitulation was signed on the 9th of October, and the garrison were preparing to march out on the 14th, when, in the English camp, the sound of a tumult in the city was heard.
“Quick, Stilwell!” the earl cried, running out of his tent, “to horse! The rascals inside are breaking out into a riot, and there will be a massacre unless I can put a stop to it.”
