 From July 1874 to February 1875, Miles led a mixed force of the 5th Infantry and 6th Cavalry in campaigns against the Southern Cheyenne, Comanche and Kiowa Indians along the Red and Washita Rivers in Indian Territory and Texas.In the spring of 1876 the largest Indian confederation of the post-Civil War period formed in the northern plains, led by Sitting Bull and Crazy Horse of the Lakota Indians.The Army organized a three-pronged expedition to round up this force, but the Indians scored major victories against two of the three, stopping George Crook's southern pincer at the Battle of the Rosebud on 17 June and destroying half of the 7th Cavalry, vanguard of Alfred Terry's eastern column, at the Battle of the Little Bighorn on 25–26 June.
