Dull 
                      Knife (or Morning Star, as he was called by the Cheyennes) 
                      was not at the Little Bighorn. He was one of the few Northern 
                      Cheyenne Council Chiefs that had remained close to the White 
                      River Agency to show the whites that he wished to remain 
                      at peace. Other Chiefs who stayed at the agency were Turkey 
                      Leg, Standing Elk, Spotted Elk, Living Bear, and Black Bear.
                     
                      The most important Cheyenne Chief Little Wolf only arrived 
                      shortly after the battle ended. 
                     
                      Most of the other 44 Council Chiefs of the Northern Cheyenne 
                      were at the Little Bighorn at the time of the battle. The 
                      two Old Man Chiefs Old Bear and Black Moccasin (a/k/a Limber 
                      Lance) were regarded as the principal Chiefs. (See Father 
                      Peter Powell: People of the Sacred Mountain.)
                     
                      In some Indian accounts you can find the name Dull Knife. 
                      Often he is confused with Lame White Man. I guess the other 
                      reason is that Dull Knife's son Bull Hump, often called 
                      Dull Knife himself, was in the battle.

                    Apparently 
                      Dull Knife was either unlucky or did not have enough skill 
                      as a leader.
                     
                      It was his village that was attacked in November 1876 by 
                      the military that broke the back of the Northern Cheyenne. 
                      This after several warriors insisted that the village stay 
                      put and celebrate all night over some minor victory over 
                      other Indians. 
                     
                      It was Dull Knife and Little Wolf that separated the band. 
                      Dull Knife's people were eventually captured and sent to 
                      an army fort and imprisoned in barracks after they refused 
                      to go to another reservation. They broke out of barracks 
                      on a winter night after the military refused them food, 
                      water, and heat only to have most of them shot down. Little 
                      Wolf's band hid out for the winter and eventually surrendered 
                      under better conditions. —

                    Dull 
                      Knife was one of the most peace-loving chiefs of the Cheyenne. 
                      He was elected as a council chief in 1854 when he was some 
                      forty-six winters old. Although he was a brave warrior in 
                      his younger days, he by then already possessed the wisdom 
                      of years. He was a strong peace man, who believed that the 
                      Cheyenne and the Whites must get along together.

                    I 
                      read in Joe Starita's book about the Dull Knife family that 
                      Chief Dull Knife (or Morning Star by his Cheyenne name) 
                      had one son (Bull Hump, his eldest) and four daughters with 
                      Pawnee Woman, his first wife, who he had stolen once from 
                      the Pawnee.
                     
                      He had a second wife named Short One (or Slow Woman) who 
                      bore him three sons and three daughters.
                     
                      So altogether he had four sons and seven daughters, who 
                      were called the “Beautiful People” by the army troops.
                     
                      His wife Short One, his son Little Hump, and two daughters 
                      were killed on the flight back north in 1879.
                     
                      His youngest son was George Dull Knife, born in 1875. Because 
                      he was only about three years old in 1879 and too weak to 
                      travel the hard way, he was left behind at the Darlington 
                      agency in Oklahoma with some Cheyenne relatives. He came 
                      to Pine Ridge in 1883 with 300 other Cheyenne and settled 
                      down in Yellow Bear's Oglala camp. Since then George Dull 
                      Knife and his family is rated as Lakota not Cheyenne. —

                    This 
                      is often said to be a photo of Dull Knife. Perhaps it's 
                      Buffalo Hump, his son:
