Fort Tompkins is a fort on Staten Island in New York City, within what is now Fort Wadsworth. Construction was completed in 1860. The site was first fortified with a blockhouse in 1663. During the Revolutionary War it was the site of the American redoubt Flagstaff Fort (1776). Taken by the British, it was enlarged and used until 1783. New York State started a masonry fort in 1807-1812. In the early 1840s Captain Robert E. Lee, stationed at Fort Hamilton, proposed rebuilding the Staten Island works, which was done by 1860. It controlled Forts Morton, Hudson, and Richmond (Water Battery, later Battery Weed). It is the last of four forts in the U.S. named Fort Tompkins.
