"Sir:--The expedition you are appointed to command is to be directed against the hostile tribes of the Six Nations of Indians, with their associates and adherents. The immediate object is their total destruction and devastation, and the capture of as many persons of every age and sex as possible. It will be essential to ruin their crops now in the ground and prevent their planting more." At this time it was supposed that the expedition would reach the Indian country in the early summer, but it was not until August that the work of destruction began. Writing again of the expedition Washington said the purpose was "to cut off their settlements, destroy their crops, and inflict upon them every other mischief which time and circumstances would permit." The purpose of the expedition was primarily to destroy the crops and villages of the Indians, after which Sullivan was to move forward and capture Niagara, if such action should prove to be practicable. The expedition was to be made up of three divisions. The first was directly under the command of Sullivan; and the forces of which it was composed assembled at Easton, Pa., from which point they marched to Wyoming on the Susquehanna, and from there to Tioga Point. Here they waited for the second division under the command of General Clinton, who had sent an expedition into the Onondaga country, after which he was to assemble his forces at Canajoharie and march across the country to the head of Otsego Lake and then come down the Susquehanna River to join Sullivan at Tioga. The third division was under the command of Colonel Daniel Brodhead, who started from Pittsburgh, Pa. He never directly co-operated with Sullivan, but no doubt aided him by his movement. He left Pittsburgh on the 11th of August with a force of six hundred and fifty men. He followed the Allegheny river and passed up into the Seneca country, where he destroyed more than one hundred and fifty houses and about five hundred acres of corn. His presence in the southern portion of the Seneca country kept some of the Senecas from joining in the movement to oppose Sullivan and so lessened the Indian force at the battle of Newtown and possibly somewhat affected the expedition. The original intention was to have Brodhead join Sullivan at Genesee and aid in the movement against Niagara, but as for some reason no movement was made against Niagara there was no occasion for him to do more than he did, and no further attention need be given his movement as a part of the Sullivan expedition. Brodhead marched three hundred and eighty miles, destroyed houses, cornfields, and gardens, and did his part in destroying the Indian civilization.
