Endicott Period

Originally built as an Endicott Period concrete coastal gun battery with four 6" M1903 guns mounted on M1903 disappearing carriages. This is a one story gun battery with two magazines, each serving two guns and a central multi purpose structure. Each gun and carriage sat on a raised loading platform. Shell carts were used to move the shells from the magazine to the loading platform stairs and the shells were hand carried to the loading platform. A separate powder passage was used to bring the powder from the magazine's powder room to the loading platform. No shell or powder hoists were needed or provided. Power was provided from the Battery Thompson power plant.

World War I

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. All four of Battery Gadsden guns were transferred for service overseas on 31 Dec 1917 to Watervliet and eventually made it to France. They were returned to the U.S. in 1919 and sent to other locations. Battery Gadsden was not rearmed after World War I. All four disappearing carriages were scrapped 26 May 1920.

World War II

Battery Gadsden remained unarmed throughout World War II. In 1944 the tops of Battery Gadsden's two magazines were each fitted with a 60" Anti Aircraft searchlight on a 20' demountable wooden tower and designated as searchlights 7 and 8. A portable 18KW generator powered both searchlights. The installation was transferred for service on 23 Feb 1944 at a cost of $ 5,404.00.
