I think we know how the sad story turned out.
So I've been putting some of the text from the papers of the War Dept. into search engines and I found this, The speech of the Cornplanter and New Arrow to Major General Wayne, Chinuchshungutho, 8th December, 1792.
We thank the Great Spirit, that we with the rest of our chiefs, who were at council, have again arrived safe at our towns. According to the promise of our chiefs, made last winter in Philadelphia, we have been to council with the hostile Indians, to endeavor to bring them to a peace. After we arrived at their towns, and had acquainted them that it was the wish of General Washington to be at peace with the whole of the Indians, even those from the rising to the setting of the sun: after they had considered, they all, as one, agreed to make a peace: but as General Washington did not let us know the terms on which he would make peace, it was referred to a council the ensuing spring, where they wish he should be present.. They wish it to be considered that they were the first people the Great Spirit seated on this island, for which reason we look on the Americans as children, to call them our younger brethren.
