Description: Established in 1776, in Brooklyn, Fort Box was constructed during the Revolutionary War to thwart a potential British attack on New York. The fort’s strength was put to the test during the Battle of Brooklyn (Also known as the Battle of Long Island), though, where the American garrison was utterly overwhelmed, and the fortification was captured by British forces in one of the most one-sided battles of the American Revolution. Notes: - Fort took the form of a small diamond shaped outpost - Building was constructed on Bergen's Hill during the spring of 1776. - The site was near present day Pacific Street, above Bond Street. - The fortress was named for Major Daniel Box. - Fort Box was part of a line of entrenchments spanning from Brooklyn to Fort Greene, to Oblong Redoubt, to Fort Putnam, and finally to Left Redoubt at Wallabout Bay. - Each structure was a complete entity surrounded by a wide ditch, the sides of which were lined with pointed stakes. - Each outpost had sally-ports; Most of the line also had abatises. - It is possible that Fort Fireman may have been built on or near the same site. Information contributed by William Harris: 1. During sewer infrastructure work 3 years ago, a previously un- known water well was discovered under a thick bluestone lid just off the northeast corner of the intersection of Pacific and Bond Streets, Brooklyn, 11217. The same is sited about 16 feet from my house property line.  Relying on NYSSMM website notes and a recently discovered map referred to in 2, below, the NYC Landmarks Preservation Commission authorized the wording on the plaque, attached, which will soon be installed adjoining the well site.  2. Of enormous help in verifying the site of Fort Box, I refer here to the recently discovered Sproule map of about 1778. Sproule was employed by the conquering British to survey all military emplacements extant in Brooklyn 1776. It reveals that Fort Box was erected on a promontory created during the glacial period. This was known then as Bergen's Hill. On what is today the same city block, just around the corner, is Fort Fireman from the War of 1812, also on Bergen's Hill and with it's own GPS site.  The Sproule map at the Brooklyn Historical Society and it has been digitized and viewable online. Note: the BHS collections have recently been folded into the Brooklyn Public Library system. You will find the Sproule map contains a wealth of information previously unknown.
