where is true grit supposed to take place
True Grit (novel) As Mattie's tale begins, Chaney is employed on the Ross's family farm in West-Central Arkansas, near the town of Dardanelle in Yell County. Chaney is not adept as a farmhand, and Mattie has only scorn for him, referring to him as "trash" and noting that her kind-hearted father Frank only hired him out of pity. One day, Frank Ross and Chaney go to Fort Smith to buy some horses. Ross takes $250 with him to pay for the horses, along with two gold pieces that he always carried, but he ends up spending only $100 on the horses. Later, Ross tries to intervene in a barroom confrontation involving Chaney. Chaney kills him, robs the body of the remaining $150 and two gold pieces, and flees into Indian Territory (now Oklahoma) on his horse.
In the Valley of Elah It turns out that Deerfield is wrong. The soldiers had killed and dismembered Mike after a seemingly insignificant quarrel. The soldier who confesses to Deerfield and the police seems emotionally detached from his words and actions, apparently to suggest he suffers post-traumatic stress disorder from events of the war.
