A few days before the outbreak of the Civil War, Manigault participated in the Battle of Fort Sumter. He was colonel of the 10th South Carolina Infantry, and helped construct the batteries for the defense of Winyah Bay in Georgetown County. In March 1862, he was ordered to dismantle the coastal batteries and to ship the guns to Charleston. In April 1862, he was commanded to take his troops and report to General P. G. T. Beauregard with the Army of Mississippi.[5]
On April 26, 1863, he was promoted to brigadier general. During the war, he was wounded twice: first in Georgia at the Battle of Resaca in May 1864, and then at the Second Battle of Franklin during November 1864. His second injury prevented his return to active service.
Postbellum activities
After the war, Manigault returned to manage his rice plantation in South Carolina. From 1880 to 1886, he served as the Adjutant and Inspector General of South Carolina. He died in Georgetown County, South Carolina in 1886 and is buried in the Magnolia Cemetery in Charleston.[7]
