Red Bird made but one request, that, although sentenced to death, he should not be placed in chains. This was granted; and while, during his subsequent imprisonment at Prairie du Chien, he had frequent opportunities to escape, he declined to take advantage of them. A few months later he fell an easy victim to an epidemic then raging in the village, thus relieving the government from embarrassment, for it was felt that he was altogether too good an Indian to hang; indeed, his execution might have brought on a general border war. The murderers of Methode were also apprehended and given a death sentence; but upon the Winnebagoes promising to relinquish forever their hold upon the lead mines of southwestern Wisconsin and northwestern Illinois, President Adams pardoned all the prisoners then living. The following year (1828), a fort was erected at the Fox-Wisconsin portage, near the scene of Red Bird's surrender; being in the heart of that tribe's territory, it was called Fort Winnebago. Thereafter the Winnebagoes were kept in entire subjection. Indeed, the three forts, Howard at Green Bay, Winnebago at Portage, and Crawford at Prairie du Chien, now gave the United States, for the first time, firm grasp upon the whole of what is now Wisconsin. THE BLACK HAWK WAR In November, 1804, the Sac and Fox Indians, in return for a paltry annuity of a thousand dollars, ceded to the United States fifty million acres of land in eastern Missouri, northwestern Illinois, and southwestern Wisconsin. There was an unfortunate clause in this compact, which quite unexpectedly became one of the chief causes of the Black Hawk War of 1832; instead of obliging the Indians at once to vacate the ceded territory, it was stipulated that, "as long as the lands which are now ceded to the United States remain their property, the Indians belonging to said tribes shall enjoy the privilege of living and hunting on them." Within the limits of the cession was the chief seat of Sac power, a village lying on the north side of Rock River, three miles above its mouth. It was picturesquely situated on fertile ground, contained the principal cemetery of the tribe, and was inhabited by about five hundred families, being one of the largest Indian towns on the continent.
