Many of the Cavalry companies which made up the SC 4th Cavalry existed prior to the war as Militia Companies, and we have documentation that the Charleston Light Dragoons which became company K of the 4th Cavalry traced its roots back to pre-Revolutionary War times. This company is first mentioned in Confederate Military History as a part of the State Militia charged with guarding Fort Sumter in the summer of 1860.
The 4th Cavalry Regiment was organized in January, 1863, by consolidating the 10th and 12th Battalions South Carolina Cavalry.
The 10th Cavalry Battalion [also called 3rd Battalion] was organized during late spring of 1862 with five companies. The unit served in the Department of South Carolina, Georgia, and Florida, and in January, 1863, merged into the 4th South Carolina Cavalry Regiment. Majors James P. Adams and William Stokes were its commanding officers.
The 12th Cavalry Battalion was also known as the 4th Battalion prior to its merger into the 4th Cavalry Regiment.
The 4th Cavalry Regiment served in the Department of South Carolina, Georgia, and Florida, then in March, 1864, moved to Virginia with 1,350 officers and men. Attached to General Butler's Brigade, it participated in The Wilderness Campaign, the battles around Cold Harbor, and in various conflicts south of the James River. Transferred to Logan's command, it fought in the campaign of the Carolinas and with less than 200 men surrendered with the Army of Tennessee.
