The South Carolina 3rd Cavalry Regiment completed its organization during the spring of 1862 at Charleston, South Carolina. It was made up of men of the 8th South Carolina Cavalry Battalion and new recruits from Marion, Colleton, Beaufort, Barnwell, and Calhoun counties. The 3rd Cavalry was assigned to the Department of South Carolina, Georgia, and Florida, and confronted the Federals in various conflicts in South Carolina. Much of the time it did not serve as one command but in detachments of one, two, five, or six companies. One detachment was involved in the defense of Savannah, then the regiment saw action in the campaign of the Carolinas. It surrendered with the Army of Tennessee. Companies Company A. - Marion County.
