On the 3d of September, the governor being summoned to surrender demanded terms inadmissible, his resolution was not to be shaken, and the vertical fire was therefore continued day and night, though the British prisoners suffered as well as the enemy; for the officer commanding in the castle, irritated by the misery of the garrison cruelly refused to let the unfortunate captives make trenches to cover themselves. The French on the other hand complain that their wounded and sick men, although placed in an empty magazine with a black flag flying, were fired upon by the besiegers, although the English prisoners in their red uniforms were placed around it to strengthen the claim of humanity. The new breaching batteries were now commenced, one for three pieces on the isthmus, the other for seventeen pieces on the land front of the horn-work. These guns were brought from the Chofres at low water across the Urumea, at first in the night, but the difficulty of labouring in the water during darkness induced the artillery officers to transport the remainder in daylight, and within reach of the enemy’s batteries, which did not fire a shot. In the town the besiegers’ labours were impeded by the flaming houses, but near the foot of the hill the ruins furnished shelter for the musqueteers employed to gall the garrison, and the guns on the island of Santa Clara being reinforced were actively worked by the seamen. The besieged replied but little, their ammunition was scarce and the horrible vertical fire subdued their energy. In this manner the action was prolonged until the 8th of September when fifty-nine heavy battering pieces opened at once from the island the isthmus the horn-work and the Chofres. In two hours both the Mirador and the Queen’s battery were broken, the fire of the besieged was entirely extinguished, and the summit and face of the hill torn and furrowed in a frightful manner; the bread-ovens were destroyed, a magazine exploded, and the castle, small and crowded with men, was overlaid with the descending shells. Then the governor proudly bending to his fate surrendered. On the 9th this brave man and his heroic garrison, reduced to one-third of their original number and leaving five hundred wounded behind them in the hospital, marched out with the honours of war. The Spanish flag was hoisted under a salute of twenty-one guns, and the siege terminated after sixty-three days open trenches, precisely when the tempestuous season, beginning to vex the coast, would have rendered a continuance of the sea blockade impossible.
