Fort Tompkins (1847) (Staten Island, New York)

Staten Island · New York · Civil War

Quick BriefBuilt between 1847 and 1861 under the federal Third System of seacoast fortifications, Fort Tompkins served as a landward defense bastion protecting New York Harbor's Narrows and remained operational until circa 1898. During the Civil War, the fort was important as a mobilization center, though it saw no combat action. Now part of the Gateway National Recreation Area, the fort is preserved at Fort Wadsworth.

History & Significance

Federal rebuilding of Forts Richmond and Tompkins began in 1847 under the federal third system of seacoast fortifications, an across-the-board program of new forts sparked by the burning of Washington, DC in the War of 1812. Fort Tompkins was named for Daniel D. Tompkins, governor of New York State in the War of 1812.

The fort was in the shape of a wide rectangle with a shallow "V" on the landward side and was unusual in having no embrasures for cannon in the main fort. A seacoast cannon battery was mounted on the roof of the seacoast front, and the rest of the fort had only musket loopholes, with a ditch on the landward sides containing tunnels to counterscarp galleries providing additional musket fire against enemies in the ditch, supplemented by a few well-placed flank howitzers.

Both forts were ready for service, though still incomplete, when the Civil War broke out in April 1861. New York City was not attacked in that war, so the fort did not see action. In the 1890s new gun batteries were built under the Endicott Program, and Fort Tompkins' role in the area's defense ceased.
