From August 27, 2014 through to February 2015, the Brooklyn Historical Society will present an exhibition, “Unlocking Two Revolutionary War Era Maps”. The exhibition will include a map of New York used by British General Hugh Percy, who commanded a British Division during the Battle of Long Island. Notations that Percy made before the battle concerning American troop locations are still visible. The map was purchased jointly by the Brooklyn Historical Society and the Green-Wood Historic Fund in 2013. For more on the story of the Percy map, see this recent article in The New York Times.
