Endicott Period (1890-1910)
Part of the Harbor Defense of Portsmouth, New Hampshire.
Originally built as an Endicott Period concrete coastal gun battery with two 8" M1888MII guns mounted on M1894 Disappearing carriages. This was a two story battery with the guns located on the upper level and the magazines below. Shells were moved from the magazine level to the gun loading platform by platform ammunition lifts operated by hand. No shell or powder hoists were provided. Electrical power was furnished by the emplacement power plant.
World War I (1917-1918)
The U.S. entry into World War I resulted in a widespread removal of large caliber coastal defense gun tubes for service in Europe. Many of the gun and mortar tubes removed were sent to arsenals for modification and mounting on mobile carriages, both wheeled and railroad. Most of the removed gun tubes never made it to Europe and were either remounted or remained at the arsenals until needed elsewhere. The guns of Battery Farnsworth were ordered dismounted for use abroad on 24 Aug 1917. They were transferred to NYC on 1 Oct 1917. The carriages were ordered scrapped in May 1918. Battery Farnsworth was not rearmed.
World War II (1941-1945)
A reinforce concrete mine observation station (M1) was built on top of Battery Farnsworth gun emplacement #1 and accepted for service 13 March 1943 at a cost of $ 4,061.
Part of Fort Constitution State Historical Site, New Castle Island, Rockingham County, New Hampshire. No period guns or mounts in place.
