History & Significance

Established in the aftermath of Custer's defeat at Little Bighorn and the capture of Chief Joseph's Nez Perce at the Bear Paw Battlefield, Montana's largest military post arose on the northern frontier in 1879. Sitting Bull's presence in Canada was the primary reason for the fort's construction.

Overlooking Beaver Creek in the shadow of the Bear Paw Mountains, the fort was designed to house ten companies of infantry and cavalry charged with monitoring regional Indian groups and protecting settlers from cross-border incursions. Between 1879 and 1903, it served as a key component of national military strategy to secure the International Border with Canada and enforce containment of Native American nations.

In 1892, the first Black 10th Cavalry companies arrived, making the post a major garrison for African-American Buffalo Soldiers. In May 1898, Chaplain William T. Anderson became the first Black officer to ever command an American military fort.

A 1911 fire that destroyed the hot water tower, combined with military assessment that the original border-defense purpose no longer existed, led to the fort's closure. In 1913 the property was transferred to Montana State University as an Agricultural Research Station, and a portion was set aside for the Rocky Boy Indian Reservation.
