Coosawhatchie, South Carolina

Coosawhatchie (koo-saw-HATCH-ee) is an unincorporated community and census-designated place (CDP) located in Jasper County, South Carolina, United States at the northern head of the Broad River. It served as the headquarters for General Robert E. Lee during the early part of the American Civil War. It was first listed as a CDP in the 2020 census with a population of 57. It is accessible from Interstate 95 via Exit 28.

History
The area derives its name from its original inhabitants, the Coosaw band of Native Americans and their word for river, hatchie. A sub-group of the Muskogees, they spoke a mixture of the Muskogee and Koasati languages. Located on the King's Highway that stretched from Boston to Charleston, Coosawhatchie was settled by trappers in the 1740s. The town grew around a store owned by rice planter brothers, Henry and Daniel DeSaussure. During the American Revolutionary War, much of the town was burned by British forces in 1779. It became the seat of Beaufort District in 1788.

In 1810, the local court of equity was relocated to Coosawhatchie. Seven years later a new courthouse was constructed in town. Designed by British architect William Jay, the two story structure remained in use until 1840, when the county seat was moved to nearby Gillisonville. After 1840 Coosawhatchie declined somewhat due to the perception that its marshy terrain was unhealthy.

During the Civil War, it was the site of several small battles. Robert E. Lee made his headquarters in Coosawhatchie when he was fortifying the coastal defenses of South Carolina and Georgia during late 1861 and early 1862. To protect the railroad bridge in Coosawhatchie against Federal gunboats coming up the Broad River, Lee's troops dug massive earthworks along its banks. Lee bought and named his famous horse Traveller in Coosawhatchie.

In 1912, Coosawhatchie became part of newly created Jasper County.
