Black Kettle, chief of a band of around 800 Cheyenne Indians, plus some Arapaho, camped at Sand Creek near Fort Lyon. This, had been agreed at peace talks at Fort Lyon and Black Kettle believed he would be protected by US troops. Some warriors had left the camp to hunt buffalo, leaving mostly Women, Children and the old in camp. Black Kettle had left an American flag flying over his tipi to show that his was a friendly village. Meanwhile Colonel Chivington with 1000 volunteers had arrived at Fort Lyon where he was told that Black Kettle had not been promised any protection. Chivington and his men set off for Sand creek and on the morning of 29th November Colonel Chivington and 700 soldiers attacked the village, even though Black Kettle also raised the white flag of surrender. A few Indians escaped. However, 450 men, women and children were killed were killed. Some of Chivington men took scalps as trophies. Black Kettle managed to escape and alert other tribes so the attacks on the ranches, wagon trains and mail coaches continued. There was an enquiry into the event, with survivors and some officers who had refused to take part giving evidence. It concluded that Chivington had planned and carried out a "foul and dastardly massacre". He was never brought to justice.
