In the long history of the American Indians no name is more widely known than Osceola. At the time of his death especially, he was talked of throughout the entire country. Towns in a score of states were named for him, and there are three counties which bear his name - in Iowa, Michigan, and Florida. This was largely because of a small piece of white cloth: the violation of a flag of truce under the orders of General Jesup, then in command of the Army in Florida. Standing under the white flag, Osceola was seized, imprisoned, and died soon afterwards in captivity. He was a remarkable man; but, except for that seizure, would not have been known outside of Florida and the nearby states which furnished volunteers for the war.
