What is the summary of the Cheyenne war

Answer: The Cheyenne war was the attempt of the Northern Cheyenne to return to the north after being placed on the Southern Cheyenne reservation in the Indian Territory and due to this the USA army attempted to stop them.

Explanation: This is due to the fact that the natives suffered terrible conditions on this new land (including an outbreak of measles) and began to retaliate against the US removing them from their original land by attacking stage coaches. About 50 people died in this war.
