[FN-3] Since these sheets were in the hands of the printer, the author has discovered an official manuscript account of a grand Indian council held at Niagara, in September, 1776, by Colonel John Butler, and Lieutenants Matthews, Burnit, and Kinnesley, and Ensign Butler, with the Hurons, Chippewas, Ottawas, Pottawatamies, Missiasagas, Senecas, Cayugas, Onondagas, Oneidas, Tuscaroras, Mohawks, Delawares, Nanticokes, Squaneghiges{?}, and Conagreves{?}--in presence of Lieut. Colonel John Caldwell, then in command at Niagara. It appears that only one Oneida sachem was present and one Tuscarora. They {illegible} an address which was unanimously signed{?} by the chiefs attending the Congress declaring their intention to embark in the war, and abide the result of the contest of the King with his people. They also made a strong appeal to the Oneidas and the Tuscaroras, "to quit the {illegible}, and be strong and determined to fulfill their engagements to the King." They also exhorted the Mohawks to be strong, and assured them "that they all their western brethren, would fly to their assistance at the first cal," &c.--_Manuscripts of Gen Gansevoort._ {Transcriber's Note: The above footnote, [FN-3], from the word "Delawares" forward, the following paragraph, and its footnote are on a page that did not scan well. It is nearly illegible. The transcription presented here is a best guess.} The plan of this campaign was well devised and matured{?}. It was to be commenced by a combined movement of two divisions--the one from Pennsylvania {transiting?} the valley of the Susquehanna to the intersection of the Tioga river under General Sullivan, who was invested with the command in chief; and the other from the north under General James Clinton, which was to descend the Susquehanna from its principal source, and after forming a junction with Sullivan, the whole to proceed, by the course of the Chemung river, into the fertile country of the Senecas and Cayugas. The expedition was intended as the principal campaign of the year; since the relative military strength and situation of the two contending powers rendered it impossible that any other offensive operations could be carried on by the Americans at the same time.
