===Battery Worth===

Completed in [[1899]], '''Battery Worth''' housed eight 12-inch mortars in two gun pits. Although the battery lost half its armament in [[1918]] in accordance with the War Department policy to reduce weaponry mounted in the nation's older emplacements, the other four mortars remained active until [[1942]]. The battery became essential for Army-Navy defense activities in the 1940s by housing the Fire Control Switchboard Room, Harbor Entrance Control Post and the Harbor Defense Command Post.<ref name="NPS" />
