In the early part of 1779, General Prevost's[4] force was distributed in posts along the frontier of Georgia; Hudson's Ferry, twenty-four miles above Savannah, being the upper extremity of the chain. Watching these posts was the American general, Lincoln, with the main body of the American Army of the South, at Purrysburgh, about twenty miles above Savannah, and General Ashe, who was posted with about 2000 of the Militia of North and South Carolina and Georgia, at Briar Creek, near the point where it falls into the Savannah River. General Ashe's position appeared most secure, his left being covered by the Savannah with its marshes, and his front by Briar Creek, which was about twenty feet broad, and unfordable at that point and for several miles above it; nevertheless, General Prevost determined to surprise him. For the purpose of amusing General Lincoln, he made a show of an intention to pass the river; and, in order to occupy the attention of Ashe, he ordered a party to appear in his front, on the opposite side of Briar Creek. Meanwhile General Prevost, with 900 chosen men, made an extensive circuit, passed Briar Creek fifteen miles above the American position, gained their rear unperceived, and was almost in their camp before they discovered his approach. The surprise was as complete as could be wished. Whole regiments fled without firing a shot, and numbers without even attempting to seize their arms; they ran in their confusion into the marsh, and swam across the river, in which numbers of them were drowned. The Continental troops, under General Elbert, and a regiment of North Carolina Militia, alone offered resistance; but they were not long able to maintain the unequal conflict, and, being overpowered, were compelled to surrender. The Americans lost from 300 to 400 men, and seven pieces of cannon. The British lost five men killed, and one officer and ten men wounded. After this success, the British and American forces remained on opposite sides of the River Savannah, until the end of April, when General Lincoln, thinking the swollen state of the river and the inundation of the marshes was sufficient protection for the lower districts, withdrew his forces further inland, leaving General Moultrie with 1000 men at Black Swamp. By this movement Lincoln left Charlestown exposed to the British. General Prevost at once took advantage of this, and, on the 29th of April, suddenly crossed the river, near Purrysburgh, with 2500 men, among whom was the South Carolina Regiment, which had been considerably increased by accessions of loyalists and freed negroes.
