With peace achieved under the Treaty of Fort Laramie in 1868, the Lakota and their allies were victorious. They gained legal control of the western Powder River country, took down the forts and permanently closed the Bozeman trail. The Crow lost their hunting grounds in the Powder River region to their enemies. With the treaty, "... the States government had in effect betrayed the Crows, who had willingly helped the army to hold the posts for two years". The victory of the Lakota and their allies, however, only endured for 8 years until the Great Sioux War of 1876, when the US started to take some of their territories again, including the sacred Black Hills.
