In 1866, cloud refused to sign a non-aggression treaty at Fort Laramie and declared war on all non-Indians entering the region. He and his band of Oglala Sioux made a number of attacks against U.S. settlers and miners who were traveling the Oregon and Bozeman Trails. When Captain William Fetterman led a relief party into Indian territory in December of 1868, they were never seen again. After more battles including the Wagon Box Fight and the Hayfield Fight, the army finally evacuated the region in 1868 In the spring of 1868 a conference was held at Fort Laramie, in present day Wyoming, which resulted in a treaty with the Sioux. This treaty relinquished the Bozeman Trail in exchange for the cessation of further Indian raids. It was meant to bring peace between the whites and the Sioux. The treaty established the "Great Sioux Reserve" giving the land west of the Missouri River, including the sacred land of the Sioux, the Black Hills of the Dakota Territory, to the Indians. In the 1868 treaty, signed at Fort Laramie and other military posts in Sioux country, the United States recognized the Black Hills as part of the Great Sioux Reservation, set aside for exclusive use by the Sioux people. Red Cloud insisted that certain government forts, including Fort Laramie, be removed from Native lands before he would sign. The Sioux celebrated the signing of the treaty by burning down every abandoned fort along the Bozeman Trail. Signed by various Native parties over a period of months after hard negotiations, this treaty sought to establish peaceful relations between the United States and Indian parties, as well as to settle reservation boundaries within which Indian people agreed to settle.
