Sullivans Island in Charleston County, South Carolina — The American South (South Atlantic)
Battery Jasper, the primary Endicott System battery on Sullivans Island, was rushed to completion in 1898 when the Spanish-American War began. This massive, reinforced-concrete structure before you was named for Sgt. William Jasper. Revolutionary War defender of the palmetto log fort.
Four powerful 10-inch disappearing rifles were mounted on the deck of Battery Jasper. These new, breech-loading weapons each weighed 55 tons, had a range of 8.5 miles, and fired shells weighing 571 pounds.
You may explore Battery Jasperís gun deck and the cave-like magazine (shell room) beneath the gun deck, walking in the footsteps of soldiers who stood ready to defend against enemy attack.
Lt. Johnson Haywood of Company C,
1st Artillery, recalled the hectic days.
“A thousand and one parts, all the way from nuts and bolts in gunny sacks up to twenty and thirty ton pieces of steel had been dumped haphazardly in the sand wherever the transportation contractor had found it convenient to his purpose. I had to collect these things together, clean them up, and fit them together, all without any instructions.”

More about this marker. A drawing in the upper right of the marker shows the loading process for the big guns at Battery Jasper. The text says “The breech-loading disappearing rifle (1) rose above the parapet to fire, then recoiled, (2) moving back and down, “disappearing” behind the wall to allow the crew to reload in safety.
Artillery crews worked in the shell room, deep within Battery Jasper. Overhead trolleys (3) moved the 571-pound shells (4) to the chain hoist, (5) which raised the shells to the gun deck (6) above.”
