The Crow Scouts were involved in the only armed conflict between the United States and the Crow tribe of which US state?
Crow scouts Enlisted Crow Scouts were first used by the United States Army in 1876 during the Great Sioux War. Because the Crow tribe was peaceful with the Americans and in particular, because parts of the old Crow country was flooded with hostile Lakotas, Northern Cheyennes and Arapahoes (Northern Arapaho), the army was able to enlist Crow warriors to help track hostile Native Americans. Already in 1873, the Crows had called for U.S. military actions against the Indian invaders in the Crow reservation. They were just waiting to offer their expertise. A small group of Crow scouts witnessed General George A. Custer's defeat at the Battle of the Little Bighorn in the Crow reservation. Many Crows served against the Nez Percés in 1877, and again in the Bannock War the next year. Crow scouts rode along with Assiniboines, Bannocks and Cheyennes during Colonel Nelson A. Miles search for Sitting Bull north of the Missouri in 1879. Some former scouts fought in the Crow War of 1887.
