Two Moons (1847–1917), or Ishaynishus, was the son of Carries the Otter, an Arikara captive who married into the Cheyenne tribe. Perhaps known best for his participation in battles such as the Battle of the Rosebud against General Crook on June 17, 1876, in the Montana Territory, the Battle of Little Big Horn on June 26, 1876 and what would prove to be his last battle which was that of the Battle of Wolf Mountain on January 8, 1877. Two Moons defeat in the battle at Wolf mountain by General Nelson A. Miles would inevitably lead to the surrender of his Cheyenne band at Fort Keogh in April, 1877.

After the surrender of Two Moons Cheyenne band in 1877, Two Moons would choose to enlist as an Indian Scout for the same General Nelson A. Miles that he had not long since surrendered to. As a result of Two Moons pleasant personality, the friendliness that he showed towards the whites as well as his ability to get along with the military, Two Moons was thus appointed head Chief of the Cheyenne Northern reservation by General Nelson A. Miles. Under the title as head chief, Two Moons would prove to play a crucial role in the assistance of the surrender of Chief Little Cow's Cheyenne band to Fort Keogh.
