Battery Decatur was a reinforced concrete Endicott Period gun battery with two, 10" BLR M1888 guns mounted on a M1894 disappearing carriages. Construction probably started in 1892 or 1893 but was halted pending the development of what became the M1894 disappearing carriage. Work resumed in 1896 or 1897 and the Battery was accepted for use 6 Jul 1899.

The Battery seems to have been deactivated sometime in 1918. The two guns were removed and sent to Fort Moultrie in March of 1919. The carriages were scrapped in 1920.
