Book excerpt: Some of the most dramatic and consequential events of the Civil War era took place in the South Carolina Lowcountry between Charleston and Savannah. From Robert Barnwell Rhett's inflammatory 1844 speech in Bluffton calling for secession, to the last desperate attempts by Confederate forces to halt Sherman's juggernaut, the region was torn apart by war. This history tells the story through the experiences of two radically different military units--the Confederate Beaufort Volunteer Artillery and the U.S. 1st South Carolina Regiment, the first black Union regiment to fight in the war--both organized in Beaufort, the heart of the Lowcountry.
