In response to the complaints of the settlers, Governor Reynolds, of Illinois, called out sixteen hundred mounted volunteers and marched them to the Island and General Gaines at Saint Louis proceeded immediately to the scene of action with the Sixth United States Infantry. General Gaines ordered all the settlers to move to the Island, and then invited Black Hawk to talk over the situation. The military and settlers met in the Council House, and Black Hawk, with about one hundred warriors in their war paint, approached and entered and soon commenced shouting in an intimidating manner. It was thought that an attempt at a general massacre would be made. An Indian called "The Prophet" raised his voice very high, gesticulating and speaking rapidly in an angry tone as if he desired to excite the warriors to an attack. At length quiet was obtained and General Gaines spoke to Black Hawk, reminding him of the sale of the lands in dispute to the United States Government. Black Hawk and his followers claimed that the lands had never been sold. The treaty was then read and explained to the chief, which seemed to enrage him greatly. Black Hawk shouted: "The white people speak from paper, but the Indian always speaks from the heart." He further said that their lands had not been sold, that the men who signed the treaty had no authority to do so, or to sell their land. And even if it was sold, they were not paid for it. The General said that the Government had assigned him and his people land on the west side of the Mississippi. His only answer was that he would neither leave nor fight and if the whites attempted to drive him off, he would sit down in his wigwam and they might do what they liked with him. General Gaines understood by this that he would defend what he considered his rights. Preparations for an attack were now made by the commanding officers and Governor Reynolds, and on June 19, 1831, troops were assembled near the mouth of Rock River. The next morning they moved upon the Indian village. Black Hawk, however, and all his people had left in the night, crossed the Mississippi and were camped a few miles below Rock Island. Ten days after, the chief presented himself on the Island with twenty-seven warriors and voluntarily signed a treaty of peace with General Gaines and the Governor of Illinois, the latter representing the National Government. The terms of this treaty included a pledge on the part of Black Hawk not to return to the east side of the river or give any more trouble to the white settlers.
