At the time it disbanded, the commission was widely seen as a failure, as violence had already returned to the Southern Plains, following the collapse of the agreements made at Medicine Lodge. In the following month, George Armstrong Custer fought the Cheyenne at the Battle of Washita River, and by 1876, would fight his final battle after open war again broke out with the Sioux, despite the agreement at Fort Laramie that all parties would forever cease hostilities. The second Treaty of Fort Laramie would eventually be modified three times by the Congress between 1876 and 1889, each time taking more of the of land granted through the agreement with the commission, including unilaterally seizing the Black Hills in 1877.
