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." The earl leaped on to his horse, called to a few orderly dragoons who were at hand to accompany him, and ordered that four companies of grenadiers should follow as quickly as possible.
Galloping at full speed Peterborough soon arrived at the gate of San Angelo, and ordered the Spanish guard to open it.

This they did without hesitation, and followed by his little party he rode into the city.
