The Dull Knife Fight, or the Battle on the Red Fork, part of the Great Sioux War of 1876, was fought on November 25, 1876, in present-day Johnson County, Wyoming between soldiers and scouts of the United States Army and warriors of the Northern Cheyenne. The battle essentially ended the Northern Cheyennes' ability to continue the fight for their freedom on the Great Plains.
Background
After soldiers from Fort Fetterman in Wyoming Territory under Brigadier General George Crook fought the Northern Cheyenne at the Battle of Powder River, on March 17, 1876, the Battle of Prairie Dog Creek on June 9, 1876, the Battle of the Rosebud on June 17, 1876, and the Battle of Slim Buttes on September 9–10, 1876, General Crook received reinforcements at his Goose Creek, Wyoming supply base and began to move up the old Bozeman Trail towards Crazy Horse. After learning of a village of Cheyennes in October, 1876, Crook sent Colonel Ranald S. Mackenzie into the Southern Powder River Country to locate it.
Colonel Mackenzie departed Camp Robinson, Nebraska with nearly 1,000 soldiers in 11 companies of the 2nd, 3rd, 4th, and 5th United States Cavalry Regiments. He also had a large contingent of 400 Indian scouts, including Pawnee led by Li-heris-oo-li-shar, Shoshone led by O-ho-a-tay, Arapaho led by "Sharp Nose", Sioux led by "Three Bears", Bannocks led by Tup-si-paw, and Cheyenne. The expedition of 1500 officers and men left Fort Fetterman on 14 November 1876, accompanied by four dismounted companies of the 4th Artillery and eleven companies of infantry from the 4th, 9th, 14th and 25th regiments under Colonel Richard I. Dodge, and a medical staff of 6 surgeons. The Indian scouts "scoured" the front, flank and rear up to . The cavalry then pushed forward, ready to fall back on the infantry if necessary. A train of some 168 wagons, 7 ambulances, 219 drivers and attendants, 400 mules and 65 packers in the pack-train supplied the column. They waited out a snow storm at Cantonment Reno until 22 Nov.
The battle
On 23 Nov., a Cheyenne Indian from the Red Cloud Agency informed the soldiers of an "extremely large" Cheyenne village at the source of Crazy Woman Creek, further upstream from the current US camp, in a Bighorn Mountains canyon. Col. Mackenzie was ordered to take the Indian scouts, and all of the cavalry except one company, in search of the village. He led 1000 men, one third of which were Indians. The Cheyenne village of 200 lodges and all its contents were entirely destroyed, and the soldiers captured about 700 "head of stock".
Other survivors never surrendered. A large number of Dull Knife's band traveled north along the Bighorn Mountains, eventually reaching the upper Tongue River regions. Some joined Chief Crazy Horse's Oglala Sioux camp on Beaver Creek, and on January 8, 1877, would fight alongside Crazy Horse and Two Moon at the Battle of Wolf Mountain on the banks of the Tongue River, in Montana Territory.
The Dull Knife Fight ended the Northern Cheyennes' resistance to the United States for all practical purposes. General Crook telegrammed the War Department, "This will be a terrible blow to the hostiles, as those Cheyennes were not only their bravest warriors but have been the head and front of most all the raids and deviltry committed in this country."
