A six week war from August through September 1862 constitutes a turning point in American Indian relations. With the nation preoccupied with the Civil War, Little Crow leads his band of Santee Sioux against the settlers in frontier Minnesota. Outnumbered, the settlers must band together under experience of local elders and the leadership of Colonel Henry Sibley. Little Crow will set Minnesota ablaze and drive thousands of settlers fleeing east. It will be the bloodiest massacre of civilians up to this point in American history.
