The Battle of the Little Bighorn, fought on June 25, 1876, near the Little Bighorn River in Montana Territory, pitted federal troops led by Lieutenant Colonel George Armstrong Custer (1839-76) against a band of Lakota Sioux and Cheyenne warriors.

After a secret meeting, a death sentence was approved on the imperial family, and Nicholas, his wife, his children, and several of their servants were gunned down on the night of July 16.
