The next morning Prevost crossed Ashly River, and encamped just without cannon shot of the works. The town was summoned to surrender, and the day was spent in sending and receiving flags. The neutrality of South Carolina during the war, leaving the question whether that state should finally belong to Great Britain or the United States, to be settled in the treaty of peace, was proposed by the garrison, and rejected by Prevost; who required that they should surrender themselves prisoners of war. This proposition being also rejected, the garrison prepared to sustain an assault. But an attempt to carry the works by storm was too hazardous to be made; and Prevost came to the prudent resolution of decamping that night, and recrossing Ashly River.

The British army passed into the island of St. James, and thence to that of St. John's, which lies south of Charleston harbour; soon after which General Lincoln encamped in the neighbourhood, so as to confine them in a great degree to the island they occupied. This island is separated from the main land by an inlet, to which the name of Stono River has been given; and the communication is preserved by a ferry. A British post was established upon the main land at this ferry, and works were thrown up in front for its defence. When Prevost commenced his retreat, and the troops were moving from island to island, the occasion seemed a fair one for attacking it. Only eight hundred men, commanded by Lieutenant Colonel Maitland, defended it; but a large corps still lay on the island. To prevent these troops from supporting those on the main land, General Moultrie, who commanded in Charleston, was ordered to pass over a body of militia into James's island, who should amuse the enemy in St. John's, while a real attack should be made on the post at the ferry. Lincoln attacks the British at the ferry but without success.About seven in the morning, General Lincoln commenced this attack with about one thousand men; and continued it with great spirit, until he perceived that strong reinforcements were crossing over from the island; when he called off his troops, and retreated, unmolested, to his old ground.

General Moultrie had been unable to execute that part of the plan which devolved on him. Boats were not in readiness to convey the men into James's island, and consequently the feint on St. John's was not made.

The loss of the Americans, in killed and wounded, amounted to twenty-four officers, and one hundred and twenty-five privates. That of the British was stated to be rather less.

Three days after this action, the posts at Stono and St. John's were evacuated. The heat now became too excessive for active service; and the British army, after establishing a post on the island contiguous to Port Royal and St. Helena, retired into Georgia and St. Augustine.

The American militia dispersed, leaving General Lincoln at the head of about eight hundred men; with whom he retired to Sheldon, where his primary object was to prepare for the next campaign, which it was supposed would open in October.

The invasion of the southern states wore so serious an aspect, that Bland's regiment of cavalry, and the remnant of that lately Baylor's, now commanded by Lieutenant Colonel Washington, with the new levies of Virginia, were ordered to repair to Charleston, and to place themselves under the command of General Lincoln. The execution of these orders was for a time suspended by the invasion of Virginia.

An expedition against that state had been concerted in the spring between Sir Henry Clinton and Sir George Collier, the Commander-in-chief of the British naval force on the American station. Invasion of Virginia by General Matthews.The land troops assigned to this service were commanded by General Matthews. The transports, on board of which they embarked, were convoyed by the Admiral in person. On the 9th of May the fleet entered the Chesapeake, and the next day anchored in Hampton Roads.

Virginia had raised a regiment of artillery for the performance of garrison duty in the state, which had been distributed along the eastern frontier; and slight fortifications had been constructed in the most important situations, which were defensible on the side of the water, but were not tenable against a military force strong enough to act on land. Fort Nelson, on the west side of Elizabeth river, garrisoned by about one hundred and fifty soldiers, commanded by Major Matthews, was designed to protect the towns of Norfolk and Portsmouth, which were on each side of the river just above it; and the town of Gosport, which lies still higher up on a point of land intervening between two branches of the river. Norfolk and Portsmouth were places of the most considerable commerce in Virginia. Large supplies for the army were deposited in them; and the state government had established at Gosport a marine yard, where ships of war and other vessels were building, for which naval stores were collected to a very great amount. The destruction of these vessels and stores, constituted the principal object of General Matthews.

On the morning of the tenth, the fleet entered Elizabeth river, and the troops were landed about three miles below the fort, without opposition. Foreseeing that the works would be attacked the next morning on the land side, the garrison evacuated the fort in the night, and took refuge in a deep and extensive swamp, called the Dismal, which could not be penetrated without difficulty, even by single persons.
