The successful defence of Fort Moultrie, on Sullivan's island, is justly considered one of the noblest achievements recorded in the annals of the Revolution.
The reduction of the southern colonies to obedience, was deemed a measure of prime importance by the British government, nor was it considered a project of difficult achievement. Hitherto the principal theatre of the war had been in the north; and, hence, it was calculated that preparations for the defence of the southern colonies had been so much neglected, that little more than a demonstration in that quarter would be necessary to bring the people to terms.
Early in 1776, an expedition having the above object in view was devised, the command of which was entrusted to Sir Peter Parker and Earl Cornwallis. Accordingly, on the 3d of May, Admiral Parker, with twenty sail, arrived at Cape Fear, with Generals Cornwallis, Vaughan, and several others.
General Clinton was expected from New York, with another considerable corps, to cöoperate in the attack. With his troops he had arrived at the point of destination, even anterior to the naval armament; and, being the senior general, on the junction of the forces, assumed the command. The immediate object was the reduction and possession of Charleston, the capital of South Carolina; on the fall of which, the subjugation of that and the other southern provinces would be an easy achievement.
The meditated invasion was not unknown to the Carolinians, who, being a high-minded and chivalrous people, determined that if their capital fell, it should be at an expense of a treasure of British blood.
With great activity and energy, therefore, they betook themselves to the fortification of every assailable point. With patriotic disinterestedness, the citizens demolished their valuable store-houses on the wharves to supply materials for defence. Streets were barricaded, and intrenchments erected along the shore. Even windows were stripped of their weights, to supply the demand for bullets. The inhabitants generally came to the work of defence, and scarcely a man on the ground could be discovered without a spade, a pickaxe, or other implement of work. Even the blacks from the city, and for miles in the country, were employed, and seemed animated with the enthusiasm and zeal of their masters. The commanding general was Major-general Lee, who, having been appointed by congress to the command of the southern forces, and possessing the entire confidence of the troops and of the people, was enabled to carry to completion the various works of defence, which his knowledge and skill had decided to be important. Governor Rutledge, also a man of great influence in the province, cöoperated with General Lee, in all his measures of defence, and by his example and exhortations essentially contributed to the happy results which followed.
At the distance of six miles from the point of land formed by the confluence of the two rivers, Ashley and Cooper, and on which Charleston is built, lies Sullivan's island. It commands the channel which leads to the port. The due fortification of this point was a matter of great moment. The outline of a fort had already been marked out, to complete which, Colonel William Moultrie, a singularly brave and accomplished officer, was dispatched early in March. Palmetto trees, which from their soft and spongy texture, were admirably calculated to deprive a ball of its impetus without causing splinters, had been cut in the forest, and the logs in huge rafts lay moored to the beach. "Ignorant of gunnery, but confident in their own resources, and nerved with resolute courage, Moultrie and his coadjutors, hardy sons of the soil, heaved those huge logs from the water, and began the work. A square pen was built, with bastions from each angle, capable of covering a thousand men. The logs were laid in two parallel rows, and sixteen feet apart; bound together with cross-timbers dove-tailed and bolted into logs, and the wide space filled with sand. When completed, it presented the appearance of a solid wall, sixteen feet wide; but its strength was yet to be tested. Behind this, Moultrie placed four hundred and thirty-five men, and thirty-one cannon, some of them twenty-sixes, some eighteens, and the rest of smaller caliber—throwing in all five hundred and thirteen pounds.
"It was at this juncture that Lee arrived from the north, and took command of the troops. When his eye, accustomed to the scientific structures of Europe, fell on this rudely-built affair, he smiled in derision, calling it a 'slaughter-pen,' and requested Governor Rutledge to have it immediately evacuated. But that noble patriot was made of sterner stuff, and replied, 'that while a soldier remained alive, he would never give his sanction to such an order.'"
The naval force of the British, consisted of the Bristol and Experiment, of fifty guns; four frigates, the Active, the Acteon, the Solebay, and the Syren, of twenty-eight; the Sphynx, of twenty, the Friendship, of twenty-two, two smaller vessels of eight, and the Thunder, a bomb-ketch. On reaching the bar, at the entrance of the channels of Charleston, it was found that the fifty-gun ships could not pass without being lightened. The removal and rëplacement of their guns was attended with incredible labor; and although thus lightened, they struck, and for a time were in danger of bilging.
Meanwhile, General Clinton issued his proclamation, which he dispatched to the city with a flag, demanding the citizens to lay down their arms, and to return to their allegiance, on pain of an immediate attack, and an utter overthrow. To this demand, not even the civility of a reply was accorded, and the threatened attack, on the morning of the 28th of June, was commenced.
