Explanation:

The U.S. army retaliated by attacking the camp and killing over 150 people, mostly women and children. ... General Sheridan ordered the U.S. army to destroy the Kiowa and Comanche villages, kill and hang all warriors, and bring back all women and children. The Red River War crushed the resistance on the Southern Plains. During the ensuing Wounded Knee Massacre, fierce fighting broke out and 150 Indians were slaughtered. The battle was the last major conflict between the U.S. government and the Plains Indians. By the early 20 century, the American-Indian Wars had effectively ended, but at great cost.
