Having a history that dates back more than two centuries, Fort Moultrie, located on Sullivan’s Island off the coast of Charleston, South Carolina, has a long history of seacoast defense, encompassing three different forts over the years.
The first fort began to be built to protect the city of Charleston in 1776. Constructed of palmetto logs, these inspired the state flag and nickname — Palmetto State — of South Carolina. The fortress was still incomplete when British Admiral Sir Peter Parker and nine warships attacked it on June 28, 1776. After a nine-hour battle, the ships were forced to retire, and Charleston was saved from British occupation. The fort was then named in honor of its commander, William Moultrie. However, four years later, the British would attack again, taking the fort and the city of Charleston.
When the American Revolution was over, Fort Moultrie was neglected, and by 1791, little of it remained. Then, in 1793, war broke out between England and France. The following year Congress, seeking to safeguard American shores, authorized the first system of nationwide coastal fortifications. A second Fort Moultrie, one of 20 new forts along the Atlantic Coast, was completed in 1798. It, too, suffered from neglect and was finally destroyed by a hurricane in 1804. By 1807 many of the other First System fortifications needed extensive repair. Congress responded by authorizing funds for a Second System, which included a third Fort Moultrie. By 1809 a new brick fort stood on Sullivan’s Island.
Between 1809 and 1860, Fort Moultrie changed little. The parapet was altered and the armament modernized, but the significant improvement in Charleston’s defenses during this period was the construction of Fort Sumter at the harbor entrance. The forts ringing Charleston Harbor – Forts Moultrie, Sumter, Johnson, and Castle Pinckney — were meant to complement each other, but, ironically, they received their first shots as opponents.
In December 1860, South Carolina seceded from the Union, and the Federal garrison abandoned Fort Moultrie for the stronger Fort Sumter. Three and a half months later, Confederate troops shelled Fort Sumter into submission, plunging the nation into Civil War. In April 1863, Federal ironclads and shore batteries began a 20-month bombardment of Fort Sumter and Moultrie, yet Charleston’s defenses held. When the Confederate army evacuated the city in February 1865, Fort Sumter was little more than a pile of rubble, and Fort Moultrie lay hidden under the bank of sand that protected its walls from Federal shells. The new rifled cannon used during the Civil War had demolished the brick-walled fortifications.
Fort Moultrie was modernized in the 1870s, employing concepts developed during the war. Huge new cannons were installed, and magazines and bombproofs were built of thick concrete, then buried under tons of earth to absorb the explosion of heavy shells. In 1885, President Grover Cleveland appointed Secretary of War William C. Endicott to head a board to review the coastal defenses of the United States and recommend how they might be improved in light of newly developing weapons technology. The system that emerged, named for Endicott, again modernized the nation’s fortifications. New batteries of concrete and steel were constructed in Fort Moultrie. Larger weapons were emplaced elsewhere on Sullivan’s Island, and the old fort became just a small part of the Fort Moultrie reservation that covered much of the island.
As technology changed, harbor defense became more complex. The world wars brought new threats of submarine and aerial attacks and required new means of defense at Moultrie. Yet, these armaments also became obsolete as nuclear weapons and guided missiles altered the entire concept of national defense.
Today, Fort Moultrie has been restored to portray the significant periods of its history, from the time of the earliest European settlements to the end of World War II. The story of two centuries of seacoast defense is told through a unique plan of restoration. Five sections of the fort and two outlying areas, each mounting typical weapons, represent a different historical period in the life of the three Fort Moultries.
