General Atkinson, with two and a half regiments of United States soldiers, forcibly moved 4,500 Winnebagoes to the west side of the Mississippi; from 1840 to 1848 six companies of soldiers were kept in Wisconsin.

The evidence

• “In the treaty of 1837 they had agreed to remove within eight months, but by October, 1839, had not yet made any general effort to do so. Therefore in 1840 General Atkinson with two and a half regiments of United States soldiers forcibly moved 4,500 of them to the west side of the Mississippi. Some 300 Winnebagoes, however, did not leave our territory, and from 1840 to 1848 six companies of United States soldiers were kept in Wisconsin to protect the citizens and remove the renegades, but the latter effort failed.”
