Running Antelope or Tȟatȟóka Íŋyaŋke became a head chief of the Húŋkpapȟa in 1851. Known for his bravery in war, and skills in oratory and diplomacy, Running Antelope was one of four Huŋkpapȟa principal chiefs who acted as close advisors to Sitting Bull during the Plains Indian Wars. His belief that compromise with the whites was in their best interests led to his eventually distancing himself from Sitting Bull. He is the only Native American depicted on U.S. paper money, but the picture caused ill will as the Series 1899 $5 Silver Certificate pictured Running Antelope as a chief wearing a Pawnee head dress as the original Sioux head dress was too tall for the engraving.

Fort Rice was a frontier military fort in the 19th century named for American Civil War General James Clay Rice in what was then Dakota Territory and what is now North Dakota. The 50th Wisconsin Infantry Regiment became the garrison in October 1865.
