Sumter's men had been wary to the possibility of surprise attacks, which were a popular British tactic. His officers had ordered their men to lie on their arms, to keep their fires burning, and had specific instructions about how to form up in case of attack. When Wemyss led the British attack against Sumter's sentries, he was hit twice by musket fire and went down. His dragoons continued the charge into the camp, where the campfires illuminated them, providing easy targets for Sumter's men, who had lined up in the woods just outside the camp. Their first volley took the British lead company by surprise, killing and wounding several men. They retreated, and Wemyss infantry then advanced into the camp, where they also came under fire from the woods. The British attempted a bayonet charge, but it was confounded by a fence between the two lines in the darkness. After twenty minutes of battle, the British retreated, leaving their wounded, including Major Wemyss, on the field.
Sumter played virtually no role in the battle, escaping from his tent to the riverbank early in the action.
