What was he last major battle between white Americans and the Indians?

The last major battle between white Americans and Native Americans is generally considered to be the Battle of Wounded Knee, which took place on December 29, 1890. This tragic confrontation occurred in South Dakota when U.S. troops attempted to disarm a band of Lakota Sioux, resulting in the deaths of around 300 Native Americans and 25 soldiers.
