Boone Hall plantation near Charleston is hosting the annual event. In June 1862, Confederate forces stopped a Union bid to take the city.
Although the battle was minor, it served as a powerful propaganda victory, increasing morale particularly in Charleston and offsetting recent Confederate losses in the Western Theater.
Hundreds of re-enactors are expected to take part Saturday and Sunday. About a dozen sutlers will be on hand.
