was a short-lived Indian victory.

Explanation:

The Sioux leaders on the Great Plains, Sitting Bull, and Crazy Horse vigorously opposed the U. S. government's attempts in the mid-19th century to constrain their people to Indian reservations. The Battle of Little Bighorn was fought between Sioux leaders and Cheyenne warriors who have outnumbered the federal troops led by Lieutenant Colonel George Armstrong Custer. Around two hundred soldiers died in the battle and U. S forces justified the event to showcase the wild nature of native Indians. And therefore the efforts to confine native tribes were increased after this event.
