The Dog Soldiers and their allies nearly obliterate a force of U.S. Army scouts, but the charismatic warrior, Roman Nose, is slain in a battle on a tributary of the Republican River in northeastern Colorado in late summer of 1868. A few months later, on November 27, nearly four years to the day after Sand Creek, the 7th U.S. Cavalry under Lt. Col. George A. Custer launches a surprise attack on Chief Black Kettle's village on Washita Creek in what is now Oklahoma. The village is destroyed. Black Kettle, a staunch peace advocate to the end, is killed, along with his wife and over 100 other Cheyenne men, women, and children. General Phillip Sheridan reportedly remarks on hearing of Black Kettle's death,
"So the old scoundrel is dead at last." The Comanche, Kiowa, Cheyenne, and Arapaho tribes continue the fight to save the last buffalo herds on the southern plains.
