The last of the Indian removals in Indiana occurred during Wallace's term, and only the few unwilling to leave voluntarily remained in the state. The Treaty of Chicago—signed in 1833 with the Potawatomi—led to their removal. Wallace ordered General and U.S. Senator John Tipton to remove the band of 859 Potawatomi from the vicinity of Plymouth, Indiana and send them to the Kansas Territory. Forty-two Potawatomi, mostly children, died from disease and the stress of the two-month march in what became known as the "Trail of Death".
