Fort Sumter History
Part of the Harbor Defense of Charleston. Established as one of the forts protecting the entrance to Charleston Harbor along with Fort Moultrie and Castle Pinckney.
Fort Sumter was built upon a sand bar in Charleston Harbor. Seventy thousand tons of New England granite were imported to build the base of the structure. The fort itself was a five-sided brick structure, 50' high and 170' by 190', with walls 5' thick. It was designed to house 650 men and 135 guns in three tiers of gun emplacements, it was never filled to capacity with guns or men.
U.S. Civil War

The Confederate attack on Fort Sumter on 12 Apr 1861 marked the first battle and the real beginning of the U.S. Civil War. The shelling of the fort continued for 34 hours. The fort commander, Maj. Robert Anderson, surrendered on 13 Apr 1861 and the fort remained in Confederate hands until 22 Feb 1865. During the war the fort suffered considerable damage from Union bombardments and it is estimated that 3,500 tons of shells were rained down on the fort just between Apr 1863 and Feb 1865. At the end of the war only one wall remained standing with the others just jagged piles of rubble.
Post Civil War
After the U.S. Civil War the fort was reconstructed but reduced to a two tier structure. The first tier was restored with 100-pounder Parrott rifles. The fort was unmanned 1876-1897.
