Lord Cornwallis retreats out of North Carolina.

The destruction of this party arrested the progress of Lord Cornwallis in North Carolina, and inspired serious fears for the posts in his rear. He retreated to Wynnsborough, between Camden and Ninety Six, where he waited for reinforcements from New York.

The victory obtained on the 16th of August having suggested views of more extensive conquest in the south, Sir Henry Clinton had determined to send a large reinforcement to the southern army. In the opinion that Lord Cornwallis could meet with no effectual resistance in the Carolinas, he had ordered the officer commanding this reinforcement to enter the Chesapeake in the first instance, and to take possession of the lower parts of Virginia, after which he was to obey the orders he should receive from Lord Cornwallis, to whom a copy of his instructions had been forwarded.

The detachment amounted to near three thousand men, under the command of General Leslie. It sailed on the 6th of October, and, entering James River after a short passage, took possession of the country on the south side as high as Suffolk. After a short time, Leslie drew in his out-posts, and began to fortify Portsmouth. At this place he received orders from Lord Cornwallis to repair to Charleston by water.

While Cornwallis waited at Wynnsborough for this reinforcement, the light corps of his army were employed in suppressing the parties which were rising in various quarters of the country, in opposition to his authority. Marion had become so formidable as to endanger the communication between Camden and Charleston. Tarlton was detached against him, and Marion was under the necessity of concealing himself in the swamps. From the unavailing pursuit of him through marshes which were scarcely penetrable, Tarlton was called to a different quarter, where an enemy supposed to be entirely vanquished, had reappeared in considerable force.

Sumpter had again assembled a respectable body of mounted militia, at the head of which he advanced towards the posts occupied by the British. On receiving intelligence of his approach, Earl Cornwallis formed a plan for surprising him in his camp on Broad River, the execution of which was committed to Major Wemyss. That officer marched from Wynnsborough at the head of a regiment of infantry and about forty dragoons, reached the camp of Sumpter several hours before day, and immediately charged the out piquet, which made but a slight resistance. Major Wemyss attacks and is defeated by Sumpter.Only five shots are said to have been fired, but from these Wemyss received two dangerous wounds which disabled him from the performance of his duty. The assailants fell into confusion, and were repulsed with the loss of their commanding officer and about twenty men. After this action, Sumpter crossed Broad River, and, having formed a junction with Clarke and Branan, threatened Ninety Six.

Alarmed for the safety of that post, Earl Cornwallis recalled Tarlton, and ordered him to proceed against Sumpter. So rapid was his movement that he had nearly gained the rear of his enemy before notice of his return was received. In the night preceding the day on which he expected to effect his purpose, a deserter apprised Sumpter of the approaching danger, and that officer began his retreat. Tarlton, pursuing with his usual rapidity, overtook the rear guard at the ford of the Ennoree, and cut it to pieces; after which, fearing that Sumpter would save himself by passing the Tyger, he pressed forward, with, as he states, about two hundred and eighty cavalry and mounted infantry, and, in the afternoon, came within view of the Americans, who were arranged in order for battle.

Sumpter had reached the banks of the Tyger, when the firing of his videttes announced the approach of his enemy. He immediately posted his troops to great advantage on a steep eminence, having their rear and part of their right flank secured by the river, and their left covered by a barn of logs, into which a considerable number of his men were thrown.

Tarlton, without waiting for his infantry, or for a field piece left with them in his rear, rushed to the charge with his usual impetuosity. After several ineffectual attempts to dislodge the Americans, he retired from the field with great precipitation and disorder, leaving ninety-two dead, and one hundred wounded.

After remaining in possession of the ground for a few hours, Sumpter, who was severely wounded in the action, crossed the Tyger, after which his troops dispersed. His loss was only three killed, and four wounded.
