The Admiral replied, that he was most willing to take upon himself the whole responsibility, and Nelson, nothing daunted, landed his small force on the 9th of April, three miles from the town, and the siege operations commenced. Encamping near a high rock, 2500 yards from the citadel, and the seamen working hard for several days in throwing up works, making roads, and carrying up ammunition, the fire was opened on the 12th of the same month. The works of the besiegers were mounted with four 13-inch and 10-inch mortars, an 18-inch howitzer, five 24-pounder guns, and two 18-pounder carronades. I give these details in order to show with what small means the daring enterprise was accomplished.
Lord Hood had sent in a flag of truce, summoning the city to surrender; to which M. La Combe St. Michel, the Commissioner of the National Convention, replied, “that he had red-hot shot for our ships and bayonets for our troops, and when two-thirds of his men were killed, he would trust to the generosity of the English.”
The place being now regularly invested, there was heavy firing on both sides, “the seamen minding shot,” as Nelson characteristically wrote to his wife, “no more than peas.” The besiegers' works were advanced, first to 1600 yards, and afterwards to a ridge 900 yards from the citadel; and on the 19th of May, thirty-five days after the fire was opened, the enemy offered to capitulate. The same evening, while the terms were negotiating, the advanced guard of the troops from San Fiorenzo made their appearance on the hills above the place, and on the following morning the whole army, under the command of General D'Aubant, who had succeeded Dundas, arrived just in time to take possession of Bastia.
Nelson had anticipated this, for in a letter to his wife, written during the siege, he says, “My only fear is, that the soldiers will advance when Bastia is about to surrender, and deprive our handful of brave men of part of their glory.”
But the work was already done, and Nelson writes after the surrender of the place, “I am all astonishment when I reflect on what we have achieved.” A force of 4000 men in strong defences had laid down their arms to 1200 soldiers, marines, and British seamen.
