Premise: The Battle of the Big Hole was fought in Montana, August 9–10, 1877, between the U.S. Army and the Nez Perce tribe of Native Americans during the Nez Perce War. Both sides suffered heavy casualties. The Nez Perce withdrew in good order from the battlefield and continued their long fighting retreat that would result in their attempt to reach Canada and asylum.
Hypothesis: The Battle of the Big Hole was fought in Atlanta.
