History
Established as a Federal post in September 1864 by Capt. Nelson Minor, Dakota Cavalry, on the Crow Creek Indian Reservation and it served as the agency headquarters.

This post was originally built as a 300' by 400' stockaded two company fort garrisoned by Iowa Volunteers. The stockade was later expanded to 450' by 650'. The post was abandoned on 9 Jun 1867 and troops withdrawn. In 1870 the post became a sub-post of Fort Sully (2) and in 1871 it was turned over to the Crow Creek Agency for use by the reservation. In 1878 the post was dismantled.
