The 20th Infantry Regiment, South Carolina Infantry was organized at Orangeburg, South Carolina, during the winter of 1861-1862. It was also called Keritt's Regiment. Many of the men were recruited in Sumter, Orangeburg, and Calhoun counties. In the spring of 1864 it moved to Virginia and was assigned to General Kershaw's, Kennedy's, and Conner's Brigade. On April 9, 1865 the 20th Regiment was consolidated with the 2nd Infantry Regiment and parts of the1st, 2nd, 6th, and 7th Battalions of Blanchard's South Carolina Reserves to form the (new) 2nd Regiment. The 2nd Infantry Regiment surrendered on April 26, 1865 with the Army of Tennessee near Greensboro, North Carolina.
Companies in this Regiment with the Counties of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.
