The Battle

History & Significance

The Fetterman Fight occurred during Red Cloud's War as part of broader conflict over the Bozeman Trail, which the U.S. Army sought to protect for travelers. The battle took place on December 21, 1866, near Fort Phil Kearny, Wyoming, and involved a confederation of Lakota, Cheyenne, and Arapaho tribes opposed to U.S. military presence in the region. The engagement occurred on Crow Indian land that had been guaranteed to the Crow by treaty with the U.S. government, though the Lakota and their allies were operating in the area without Crow consent.

A group of ten warriors, including Crazy Horse, executed a coordinated strategy to lure a U.S. Army detachment into an ambush. Captain William J. Fetterman commanded the American forces, which consisted of 81 men. The Native American warriors successfully executed their plan, resulting in the complete elimination of Fetterman's detachment.

The battle resulted in a decisive victory for the Lakota alliance and represented a major military setback for the United States. At the time, the Fetterman Fight constituted the worst military disaster ever suffered by the U.S. Army on the Great Plains. Following this engagement, the remaining U.S. forces withdrew from the area, demonstrating the significant impact of the Native American victory and the effectiveness of the coalition's military tactics.

Historical context

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.
