Charleston was then a town of but a few thousand inhabitants; but, small as it was, it had become particularly obnoxious to the British on account of the strong revolutionary sentiment of its people, and their many open acts of defiance of King George's authority. When the offensive Stamp Act first was published, the people of Charleston rose in revolt; and the stamps for the city being stored in an armed fortress in the bay, known as Castle Johnson, a party of a hundred and fifty armed men went down the bay, surprised the garrison, captured the castle, and, loading its guns, defied the authorities. Not until the promise had been made that the stamps should be sent back to England, did the rebellious Carolinians lay down their arms. Nor was their peace of long duration. When the news of the battle of Lexington reached the little Southern seaport, the people straightway cast about for an opportunity to strike a blow against the tyranny of England. The opportunity soon offered itself. An English sloop laden with powder was lying at St. Augustine, Fla. Learning this, the people of Charleston fitted out a vessel, which captured the powder-ship, and, eluding a number of British cruisers, returned safely to Charleston with fifteen thousand pounds of gunpowder for the colonial army. Soon after the colonial troops took possession of the forts in the harbor, and Charleston became a revolutionary stronghold. Therefore, when the war authorities of Great Britain prepared to take active, offensive measures against the seaport cities of the rebellious colonies, Charleston was one of the first points chosen for attack. It was on the 4th of June, 1776, that the British fleet, under the command of the veteran admiral, Sir Peter Parker, appeared off Charleston bar. The colonists had learned of its approach some time before; and the town was crowded with troops, both regular and volunteer. Two forts, Johnson and Sullivan, were erected at points commanding the entrance to the harbor. Troops were thrown out to oppose the advance of landing parties. The wharves were covered with breastworks, and the streets leading up from the water-side were barricaded. There was a great scarceness of lead for bullets; and to supply that need the leaden sashes, in which window-panes were at that time set, were melted down. When the fleet of the enemy appeared in the offing, Charleston was quite ready to give the invaders a warm reception.
