At midnight on the fourteenth of September, 1775, the detachment crossed to James' Island. The disembarkation was effected with delay and difficulty, occasioned by the inadequate size and number of the boats. The forlorn hope, consisting of a detachment from the grenadiers of Capt. Pinckney, joined by the Cadets, and led by Lieut. Mouatt, were to scale the walls of the fort on its south bastion; Col. Moultrie with the rest of Pinckney's Grenadiers, and Marion's Light Infantry, were to enter or force the gates over the ravelin; while Capt. Elliott, with his grenadiers, penetrated the lower battery over the left flank. It was broad daylight before the landing was effected; and on making the assault they were surprised by an easy victory. The fort was abandoned. The enemy had probably been apprised of the attack. A detachment from the ships had landed some hours before -- had dismantled the fort, dismounted the cannon, and withdrawn the garrison; retreating in safety to the ships.
A gunner and three men only, fell into the hands of the provincials.
The very day that this event occurred, Lord William Campbell, the Governor, fled to the Tamar sloop of war. His flight was no doubt hastened by a proceeding so decisive. That evening he dispatched his secretary to Fort Johnson, which he was not permitted to enter. He was met at the water-side by Capt. Pinckney, of whom he demanded, in the name of the Governor, by what authority he had taken and held possession of the fortress. The answer to this demand brought up the vessels of war, which, on the seventeenth of September, presented themselves within point blank shot of the fort. Up to this time, but three of the dismantled cannon had been remounted and put in order for action. With these, the provincials prepared for battle, relying, however, less upon their cannon than upon their ability to oppose the landing of any body of men. But the demonstration of the squadron was without fruits. They hauled off without a shot, and resumed their former less offensive position.
Here, however, the popular leaders were not disposed to suffer them to remain.
Still they hesitated at coming to blows. They adopted a middle course, which, in such cases, is generally the worst. They ordered that the ships should not be victualled or supplied with water from the city, except from day to day. This produced a threat from Captain Thornborough that, unless supplied as before, he should prevent the ingress, or departure, of any vessel from the harbor. A menace of this kind, to have been properly met, should have been answered from the eighteen pounders of Fort Johnson. And, but for the reluctance of several highly esteemed patriots, such would have been the mode of answer.
This temporizing policy continued to prevail until the 9th November, 1775, when the Provincial Congress resolved, "by every military operation, to oppose the passage of any British Armament." Such were the orders issued to the officer commanding at Fort Johnson. This fort had now been in possession of the popular party for nearly two months.
It was in some degree prepared for use. It was well manned with a portion of those brave fellows who afterwards fought the good fight of Fort Sullivan. They would have done as good service here.
The resolution of the Province once adopted, it was communicated as well to the commanders of the British vessels, as to the officers of the fort.
There was still an open passage, through Hog-Island channel, by which the British vessels might approach the town without incurring any danger from the Fort. This passage it was determined to obstruct;and an armed schooner, called the Defence, fitted up for the occasion, was ordered to cover and protect a party which was employed to sink a number of hulks in that narrow strait. This drew upon them the fire of the British. It was returned by the "Defence", but with little injury to either side. The garrison at Fort Johnson endeavored to take part in this little action, but the distance was too great for any decisive results from its fire. Some of the shots took effect, but after a few rounds the fire was discontinued. Meanwhile, the alarm was beat in Charleston, where the troops stood to their arms, and every heart throbbed with the expectation of a close and bloody fight.
But the time was not yet. Indecisive in itself, this brief combat was of great importance in one point of view. It was the beginning of the game. The blow for which all parties had been waiting, was now fairly struck. The sword had been drawn from the scabbard, not again to be sheathed, till the struggle was concluded. The local Congress proceeded vigorously. Ships were impressed for the purpose of war, new troops were enlisted and armed, and bills of credit issued.
The British vessels, meanwhile, became more than ever troublesome, and, carrying out the menace of Captain Thornborough, proceeded to the seizure of all vessels within their reach, whether going from or returning to the port. It became necessary to drive them from the roadstead. To effect this, Col. Moultrie, with a party of newly raised Provincials and the Charleston Artillery, took post on Haddrill's Point, and, mounting a few pieces of heavy artillery, opened upon them with a well-directed fire, which drove them out to sea.
This step was followed by one of preparation. The fortifications at Fort Johnson and Haddrill's Point were completed -- the city was fortified --a new fort was raised on James', and another begun on Sullivan's Island.
