Swamp Angel, ca.1907 Postcard from author’s collection |
As The Defense of Charleston, including Fort Sumter and the Adjacent Islands, 1863-1865 (Johnson 1890) tells the story, “The Swamp Angel, so called by the Union soldiers, was purchased, with a number of other condemned cannon at the close of the war by the late Charles Carr, founder, of Trenton, N.J. It lay at his foundry several years, and, being loth to melt such a historic relic, he united with a number of public-spirited citizens and took means for the preservation of the piece.”
Gillmore was tasked with taking Charleston in 1863. He determined that a long range gunnery was needed, but the nearest safe distance was five miles distant on Morris Island. Since the island was little more than a marsh, a battery was constructed in two parts. The parapet was built on piles driven into the marsh, a grillage bolted onto the pilings, and a layer of 800 tons of sand. Once the foundation was completed, the platform was built of a layer of marsh grass, canvas, and sand onto which was placed a plank deck.
