The Fetterman Fight occurred during Red Cloud's War as part of the U.S. Army's effort to protect travelers on the Bozeman Trail. Fort Phil Kearny, located in Wyoming, served as the base for military operations in the region. The engagement took place on December 21, 1866, on Crow Indian land that had been guaranteed to the Crow by the Fort Laramie Treaty of 1851. Although the Lakota, Cheyenne, and Arapaho had previously accepted this territory as Crow land, they were now operating in the area without the consent of the Crow.
A confederation of Lakota, Cheyenne, and Arapaho warriors executed a coordinated ambush strategy against U.S. forces. A group of ten warriors, including the notable Lakota leader Crazy Horse, acted to lure a detachment of U.S. soldiers into a trap. Captain William J. Fetterman commanded the U.S. detachment, which consisted of 81 men. The Native American warriors succeeded completely in their ambush, resulting in the death of all 81 men under Fetterman's command.
The Fetterman Fight resulted in a decisive victory for the Lakota alliance and represented a major military setback for the United States. At the time, this engagement was the worst military disaster ever suffered by the U.S. Army on the Great Plains. Following this defeat, the remaining U.S. forces withdrew from the area, demonstrating the significant military impact of the Native American victory.
The Indian Wars encompass more than three centuries of armed conflict between the United States government, American settlers, and Indigenous nations — from the Powhatan Wars of the 1620s through the final Plains campaigns of the late 19th century. The eastern conflicts — King Philip's War (1675–1676), the Tuscarora War (1711–1715), and the Creek and Seminole Wars — largely ended organized Indigenous resistance east of the Mississippi by the 1840s. On the Great Plains, the Sioux Wars (1854–1890), Red River War (1874–1875), and Nez Perce War (1877) followed the displacement wrought by the transcontinental railroad and the near-extinction of the American bison — an estimated 30 to 60 million animals reduced to fewer than 1,000 by 1890. The Ghost Dance religious movement and the massacre at Wounded Knee (December 29, 1890), in which US cavalry killed approximately 250 Lakota men, women, and children, marked the effective end of armed resistance. The Dawes Act (1887) allotted reservation land to individual families, opening millions of acres to white settlement and reducing Indigenous landholdings by about two-thirds over the following decades.
