The individual pioneers differed much in their morals and their cultural antecedents, but were uniform in their determination to enjoy the profits for which they had risked the dangers of the wilderness. Notable among them, and typical of their highest virtues, was Henry Dodge, later governor of Wisconsin, and representative and senator for his state in Congress, but now merely one of the first in the frontier movement. It is related of him that in 1806 he had been interested in the filibustering expedition of Aaron Burr, and had gone as far as New Madrid, to join the party, before he learned that it was called treason. He turned back in disgust. "On reaching St. Genevieve," his chronicler continues, "they found themselves indicted for treason by the grand jury then in session. Dodge surrendered himself, and gave bail for his appearance; but feeling outraged by the action of the grand jury he pulled off his coat, rolled up his sleeves, and whipt nine of the jurors; and would have whipt the rest, if they had not run away." With such men to deal with, it was always difficult to enforce unpopular laws upon the frontier. Dodge had no hesitation in settling upon his lead diggings in the mineral country and in defying the Indian agents, who did their best to persuade him to leave the forbidden country. On the west bank of the Mississippi federal authority was successful in holding off the miners, but the east bank was settled between Galena and Mineral Point before either the Indian title had been fully quieted, or the lands had been surveyed and opened to purchase by the United States. The Indian war of 1827, the erection of Fort Winnebago in 1828, the cession of their mineral lands by the Winnebago Indians in 1829, are the events most important in the development of the first settlements in the new Northwest. In 1829 and 1830 pioneers came up the Mississippi to the diggings in increasing numbers, while farmers began to cast covetous eyes upon the prairies lying between Lake Michigan and the Mississippi. These were the lands which the Sauk and Fox tribes had surrendered in 1804, but over which they still retained rights of occupation and the chase until Congress should sell them. The entry of every American farmer was a violation of good faith and law, and so the Indians regarded it. Their largest city and the graves of their ancestors were in the peninsula between the Rock and the Mississippi, and as the invaders seized the lands, their resentment passed beyond control. The Black Hawk War was the forlorn attempt to save the lands. When it ended in crushing defeat, the United States exercised its rights of conquest to compel a revision of the treaty limits.
