Answer:
Lincoln sent an expedition to look for suitable locations for a fort, find a route to the southwest, and to investigate the possibility of gold mining. The expedition set up a camp at the site of the future town of Custer; while Custer and the military units searched for a suitable location for a fort, civilians searched for gold, and it is disputed whether or not any substantial amount was found. Nonetheless, this prompted a mass gold rush which in turn antagonised the Sioux Indians who had been promised protection of their sacred land through Treaties made by the US government,[2] and who were later to kill Custer at the Battle of the Little Big Horn in the Great Sioux War of 1876–1877 between themselves and the United States.[1]
