An unusual map of Manhattan Island will adjacent parts of Long Island and New Jersey drawn in 1878 for issue in Henry P. Johnston's history of the Battle of Long Island and the loss of New York.  In compiling his history Johnston was frustrated by the lack of a Revolutionary War period map detailing the entire Island of Manhattan.  He thus compiled this map which he published with Julius Bien and incorporated into his book.  Though quite late compared to colonial period information it presents, this map is significant in that it is possibly the first map to show the whole of Manhattan Island during the Revolutionary War.  Cartographically it is based upon the work of <a href="https://en.wikipedia.org/wiki/Bernard_Ratzer" class="extiw" title="en:Bernard Ratzer">Ratzer</a> and <a href="https://en.wikipedia.org/wiki/John_Montresor" class="extiw" title="en:John Montresor">Montresor</a> with regard to the southern part of the Island as far north as 50th street.  North of 50th street it incorporates data from the <a href="https://en.wikipedia.org/wiki/Commissioners%27_Plan_of_1811" class="extiw" title="en:Commissioners' Plan of 1811">Commissioners' Plan of 1811</a> and from <a href="https://en.wikipedia.org/wiki/Claude_J._Sauthier" class="extiw" title="en:Claude J. Sauthier">Sauthier's</a> map of New York.  Beyond the developed southern portions of the city that extend north only as far as modern day Canal Street the city is laid out topographically, with hills, river courses, and plains apparent.  Bloomingdale Road (modern day Broadway) is identified as is the Kings Bridge or Post Road.  Shows various fortifications throughout  as well as military notations regarding the placement of British and American troops.  Though fiercely fought the British ultimately won the <a href="https://en.wikipedia.org/wiki/Battle_of_Long_Island" class="extiw" title="en:Battle of Long Island">Battle of Long Island</a> and the <a href="https://en.wikipedia.org/wiki/Battle_of_Fort_Washington" class="extiw" title="en:Battle of Fort Washington">Battle of Fort Washington</a>, thus seizing control of New York City, which they maintained until the end of the Revolutionary War.
