The Fetterman Massacre Monument is a rock monolith dedicated to the memory of Lieutenant William J. Fetterman and his 80 men, who died in a December 21, 1866, battle against Lakota-Sioux warriors. Today, an interpretive trail with 21 signs spans the entire length of the battlefield, explaining the combatants, leaders, weapons, tactics, positions, and theories of a battle that lasted all of 30 minutes. This was the worst defeat for the U.S military on the Northern Plains
until the Little Big Horn battle a decade later. Five miles west of the Fetterman site is the site of the Wagon Box Fight, which also has a short interpretive trail. Fort Phil Kearny is the starting point for both battle sites, providing brochures, guides, and an overview of the history of Red Cloud's War.
