In 1867 a Man by the Name of O.W. Weeler took the First Herd of 2400 Head of Texas Steers on the Chisholm Trail for the First Time.
Duke said the Man He Played in the Film "Red River" Thomas Dunson was Based on the O.W. Weeler Story.
So I think You Could Call O.W. Weeler "Thomas Dunson" a Real Character !
Below is the Story of the Chisholm Trail and the Film "Red River."
