Sauthier's draft of the conflict at Harlem Plains is reproduced in the _Mag. of Amer. Hist._, May, 1880. Later plans of the locality, drawn with reference to the landmarks of the battle, or interesting for comparison, are the map of 1814 in Valentine's _Manual_ (1856) and the large folding plan of the upper part of New York, with the modern streets, upon which, in colors, is superposed a draft of this action. This last is given, with an account of the fight, in Shannon's _N. Y. City Manual_, 1868, p. 812.[789] We may note some of the principal contemporary and later authorities on this action of Harlem Plains.[790] The origin of the fire of Sept. 21st, by which a considerable part of New York was burned, has been a subject of dispute, the Tories charging it upon the Americans;[791] but later authorities, English as well as American, agree in not believing it the work of incendiaries. It is known that Washington advocated the burning of the city if evacuation became necessary, and Jones (i. p. 84) says committees of Congress had agreed upon it, but that body certainly in the end directed Washington to spare it (_Journals_, Sept. 3, 1776).[792] [Illustration: JOHNSTON'S NEW YORK ISLAND, 1776.
