This easy triumph changed Black Hawk's purpose. He regarded it as an omen of victory and determined to go on. But his strenuous efforts to enlist the Pottawatomi in the cause were unavailing. Old Chief Shaubenee had absolute control over them and steadily said "no." Even Chief Big Foot at the head of Lake Geneva refused. He was a drunken, sullen, brutal savage, but had given his word to keep the peace and did so, though he bitterly hated the whites and would have been glad to see the war go on. About one hundred reckless, lawless individuals of the Winnebago and Pottawatomi tribes joined Black Hawk, but gradually deserted him as his fortunes waned.
Black Hawk was now anxious to take his women, children and old men to a place of safety, and, following the guidance of two Winnebagoes, they made their way up the Rock to Hustisford Rapids and there went into camp. Fish, game, clams, roots and the bark of trees constituted their food while there, but Black Hawk in his biography says they found it difficult to keep from starving. And, adding to their present misery, the thrifty, provident squaws saw another harvestless summer passing and a winter of famine before them. With his warriors he then returned to continue the contest. A few skirmishes and collisions took place along the line that now separates Wisconsin and Illinois, and predatory parties of Winnebagoes and Pottawatomi worked out their grudges and revenges on whites who had incurred their enmity. These outrages were numerous and were attributed to the Sauks, as their perpetrators expected would be the case. It is now believed that not a single case of the murder of an unarmed man or of a woman or child was justly chargeable to the Sauks.
Governor Reynolds had called for a second levy of two thousand volunteers, and General Atkinson, with a considerable force of regulars, was in the field. All were under his command, and he followed Black Hawk, as the latter retired northward, with an army of four thousand, all mounted, fully twelve times as great in number as the starving band which he was pursuing. They camped near Beloit, camped at Milton, near the south end of Storr's Lake, and followed on cautiously to Lake Koshkonong, for Atkinson had a most wholesome regard for Black Hawk's prowess. At the lake they found an old blind Sauk who had been left behind. They gave him food, but a straggler coming along later shot him as he was crawling to a spring for water. His bones lay on the ground unburied for years after the country was settled, the skull having been hung on a bush. At the junction of the Bark and Rock rivers Atkinson went into utter bewilderment and uncertainty as to Black Hawk's whereabouts, and he finally built the stockade at the point which bears his name. He dispatched a considerable force under Colonels Alexander, Dodge and Henry to Portage for supplies. There they learned where Black Hawk's camp was; Henry and Dodge set out to attack it, while Alexander returned to Atkinson. The latter had heard that Black Hawk was in full force at Burnt Village on the Whitewater River, about four miles north of the location now occupied by the city bearing that name. He sent off messengers for the remainder of the army to join him for an attack.
