Almost simultaneously the region to the west of Lake Michigan began to emerge from the fur-trading stage. The place of the picturesque trader, however, was not taken at once by the prosaic farmer. The next figure in the pageant was the miner. The presence of lead in the stretch of country between the Wisconsin and Illinois rivers was known to the Indians before the coming of the white man, but they began to appreciate its value only after the introduction of firearms by the French. The ore lay at no great depth in the Galena limestone, and the aborigines collected it either by stripping it from the surface or by sinking shallow shafts from which it was hoisted in deerskin bags. Shortly after the War of 1812 American prospectors pushed into the region, and the Government began granting leases on easy terms to operators. In 1823 one of these men arrived with soldiers, supplies, skilled miners, and one hundred and fifty slaves; and thereafter the "diggings" fast became a mecca for miners, smelters, speculators, merchants, gamblers, and get-rich-quick folk of every sort, who swarmed thither by thousands from every part of the United States, especially the South, and even from Europe. "Mushroom towns sprang up all over the district; deep-worn native paths became ore roads between the burrows and the river-landings; sink-holes abandoned by the Sauk and Foxes, when no longer to be operated with their crude tools, were reopened and found to be exceptionally rich, while new diggings and smelting-furnaces, fitted out with modern appliances, fairly dotted the map of the country." ¹
Galena was the entrepôt of the region. A trail cut thither from Peoria soon became a well-worn coach road; roads were early opened to Chicago and Milwaukee. In 1822 Galena was visited by a Mississippi River steamboat, and a few years later regular steamboat traffic was established. And it was by these roadways and waterways that homeseekers soon began to arrive.
The invasion of the white man, accompanied though it was by treaties, was bitterly resented by the Indian tribes who occupied the Northwest above the Illinois River. These Sioux, Sauk and Foxes, and Winnebagoes, with remnants of other tribes, carried on an intermittent warfare for years, despite the efforts of the Federal Government to define tribal boundaries; and between red men and white men coveting the same lands causes of irritation were never wanting. In 1827 trouble which had been steadily brewing came to the boiling-point. Predatory expeditions in the north were reported; the Winnebagoes were excited by rumors that another war between the United States and Great Britain was imminent; an incident or even an accident was certain to provoke hostilities. The incident occurred. When Red Bird, a petty Winnebago chieftain dwelling in a "town" on the Black River, was incorrectly informed that two Winnebago braves who had been imprisoned at Prairie du Chien had been executed, he promptly instituted vengeance. A farmer's family in the neighborhood of Prairie du Chien was massacred, and two keel-boats returning down stream from Fort Snelling were attacked, with some loss of life. The settlers hastily repaired the old fort and also dispatched messengers to give the alarm. Galena sent a hundred militiamen; a battalion came down from Fort Snelling; Governor Cass arrived on the spot by way of Green Bay; General Atkinson brought up a full regiment from Jefferson Barracks, near St. Louis; and finally Major Whistler proceeded up the Fox with a portion of the troops stationed at Fort Howard, on Green Bay.
