Morris Island is an 840-acre uninhabited island in Charleston Harbor in South Carolina, accessible only by boat. The island lies in the outer reaches of the harbor and was thus a strategic location in the American Civil War. The island forms parts of the cities of Charleston and Folly Beach, in Charleston County.HistoryMorris Island was heavily fortified to defend Charleston harbor, with the fortifications centered on Fort Wagner. On January 9, 1861, the first shots of the American Civil War were fired from cannons by cadets of The Citadel at the Star of the West as the ship tried to resupply Fort Sumter.It was the scene of heavy fighting during the Union Army's campaign to capture Charleston, and is perhaps best known today as the scene of the ill-fated assault by the 54th Massachusetts Volunteer Infantry, an African-American regiment. The regiment and this assault, where it suffered over 50% casualties, was immortalized in the film Glory.
