By the mid-nineteenth century, settlers were replacing the fur traders, and the military came to protect this Euro-American migration to the West.
In 1863 General Henry H. Sibley led US troops from Minnesota across Dakota Territory, pursuing bands of Dakota Indians, some of whom the military believed had participated in the US-Dakota War of 1862.
General Alfred Sully and the 2,000 soldiers in his command who traveled north along the Missouri River were also part of this military reprisal. Gen. Sully and his forces returned in 1864, still pursuing Dakota bands.
