chunk: Because of the growing Pawnee and white threat, Chief Ten Bears decides to move the tribe to its winter camp. Dunbar decides to accompany them but must first retrieve his diary from Fort Sedgewick as he realizes that it would provide the army with the means to find the tribe. However, when he arrives he finds the fort reoccupied by the U.S. Army. Because of his Sioux clothing, the soldiers open fire, killing Cisco and capturing Dunbar, arresting him as a traitor. Senior officers interrogate him, but Dunbar cannot prove his story, as a corporal has found and discarded his diary. Having refused to serve as an interpreter to the tribes, Dunbar is charged with desertion and transported back east as a prisoner. Soldiers of the escort shoot Two Socks when the wolf attempts to follow Dunbar, despite Dunbar's attempts to intervene.
