As my fellow fort visitors were settling in for their introductory chat, I was riveted by the shapes that dominated Fort Wool's parade ground: The Endicott Batteries. Five such batteries were built at Fort Wool at the start of the 20th century. Battery Claiborne was completed in 1908 and named for Ferdinand Claiborne, a Brigadier General of the US Volunteers who fought the Creek Indians in a distinctive manner during the War of 1812. This battery mounted two 6" Disappearing Rifles, which were removed in 1918, when it was popular in the US military to willy-nilly relocate large gun tubes from place to place.

In the lower center of this picture is a granite marker which denotes that Fort Wool has been placed on the National Register of Historic Places (Click here to see it), and there are two historical markers regarding the Endicott batteries: Fort Wool: Rapid-Fire Guns and Fort Wool: Endicott Batteries.
