Fort Mott is an Endicott-era fortification dating to about 1896 that was begun before the Spanish-American War. An earlier fortification, known as the Battery at Finns Point, was begun in 1872 but never completed, and parts of it were incorporated into the 1896 construction plan and remain visible at the west end of the main batteries. The fort was officially named in 1897 for Major General Gershom Mott of Burlington, New Jersey, who served with distinction in the Mexican and Civil Wars. Fort Mott has five batteries that originally mounted twelve guns: Battery Arnold with three 12-inch disappearing guns, Battery Harker with three 10-inch disappearing guns, Battery Gregg with two 5-inch rapid fire guns, Battery Krayenbuhl with two 5-inch rapid fire guns, and Battery Edwards with two 3-inch case mates rapid fire guns.
