 Until 1899, the fort was named the Long Island Military Reservation.From 1874 to 1876, the fort had a battery of 10 cannon, called the Long Island Head Battery, on the northeast tip of the raised northern portion of the island.Remains of this battery can still be found, concealed by heavy brush, about 100 feet (30 m) north of Battery Ward, the easternmost concrete battery on the tip of the island (see the map of the "Obsolete Battery" at right).
