<P> Reinforced with the Fifth Cavalry, General Crook took to the field . Hooking up briefly with General Terry, he soon moved out on his own but did not find a large village . Running short on supplies, his column turned south and made what became called the Horsemeat March toward mining settlements to find food . On September 9, 1876, an advance company from his column en route to Deadwood to procure supplies stumbled across a small village at Slim Buttes, which they attacked and looted . Crazy Horse learned of the assault on the village and the next day led a counter-attack, which was repulsed . After reaching Camp Robinson, Crook's forces disbanded . </P> <P> In the wake of Custer's defeat at the Little Bighorn, the Army altered its tactics . They increased troop levels at the Indian agencies . That fall, they attached most of the troops to the Army for operations . They seized horses and weapons belonging to friendly bands at the agencies, for fear they would be given to the resisting northern bands . In October 1876, Army troops surrounded the villages of Red Cloud and Red Leaf . They arrested and briefly confined the leaders, holding them responsible for failing to turn in individuals arriving in camp from hostile bands . The US sent another commission to the agencies . According to historian Colin Calloway, "Congress passed a law extinguishing all Lakota rights outside the Great Sioux Reservation ." </P> <P> Colonel Ranald S. Mackenzie and his Fourth Cavalry were transferred to the Department of the Platte following the defeat at the Little Bighorn . Stationed initially at Camp Robinson, they formed the core of the Powder River Expedition that departed in October 1876 to locate the northern villages . On November 25, 1876, his column discovered and defeated a village of Northern Cheyenne in the Dull Knife Fight in Wyoming Territory . With their lodges and supplies destroyed and their horses confiscated, the Northern Cheyenne soon surrendered . They hoped to be allowed to remain with the Sioux in the north . They were pressured to relocate to the reservation of the Southern Cheyenne in Indian Territory . After a difficult council, they agreed to go . </P> <P> When they arrived at the reservation in present - day Oklahoma, conditions were very difficult: inadequate rations, no buffalo left alive near the reservation, and malaria . A portion of the Northern Cheyenne, led by Little Wolf and Dull Knife, attempted to return to the north in the fall of 1877 in the Northern Cheyenne Exodus . They succeeded in reaching the north . After they divided into two bands, that led by Dull Knife was captured and imprisoned in an unheated barracks at Fort Robinson without food or water . When the Cheyenne escaped on January 9, 1878, many died at US Army hands in the subsequent Fort Robinson massacre . Eventually the US government granted the Northern Cheyenne a northern reservation, the Northern Cheyenne Reservation in present - day southern Montana . </P>
