The pursuers came up with the savages at Prairie du Sac. Here the south bank of the Wisconsin consists of steep, grassy bluffs, three hundred feet in height; hence the encounter which ensued is known in history as the Battle of the Wisconsin Heights. With consummate skill, Black Hawk made a stand on the summit of the heights, and with a small party of warriors held the whites in check until the noncombatants had crossed the broad river bottoms below, and gained shelter upon the willow-grown shore opposite. The loss on either side was slight, the action being notable only for the Sac leader's superior management. During the night, the passage of the river was accomplished by the fugitives. A large party was sent downstream upon a raft, and in canoes begged from the Winnebagoes; but those who took this method of escape were brutally fired upon near the mouth of the river by a detachment from the garrison at Prairie du Chien, and fifteen were killed in cold blood. The rest of the pursued, headed by Black Hawk, who had again made an attempt to surrender his forces, but had failed for lack of an interpreter, pushed across country, guided by Winnebagoes, to the mouth of the Bad Ax, a little stream emptying into the Mississippi about forty miles above the mouth of the Wisconsin River. His intention was to get his people as quickly as possible on the west bank of the Mississippi, in the hope that they would there be allowed to remain in peace. The Indians were followed, three days behind, by the united army of regulars, who steadily gained on them. The country between Wisconsin Heights and the Mississippi is rough and forbidding in character; there are numerous swamps and rivers between the steep, thickly wooded hills. The uneven pathway was strewn with the corpses of Sacs who had died of wounds and starvation; and there were frequent evidences that the fleeing wretches were sustaining life on the bark of trees and the flesh of their fagged-out ponies. On Wednesday, the 1st of August, Black Hawk and his now sadly depleted and almost famished band reached the junction of the Bad Ax with the Mississippi. There were only two or three canoes to be had, and the crossing of the Father of Waters progressed slowly and with frequent loss of life. That afternoon there appeared upon the scene a government supply steamer, the _Warrior_, from Fort Crawford (Prairie du Chien), at the mouth of the Wisconsin. The Indians a third time tried to surrender, but their white flag was deliberately fired at, and round after round of canister swept the camp.
