The Federal officers failed to prosecute the Soldiers for the violation of the law of war. Tennessee Historical Marker between Nolensville and Triune commemorates Jobe’s death: “DeWitt Smith Jobe, a member of Coleman's Scouts, CSA, was captured in a cornfield about 1 1/2 miles west, Aug. 29, 1864, by a patrol from the 115th Ohio Cavalry. Swallowing his dispatches, he was mutilated and tortured to make him reveal the contents. Refusing, he was dragged to death behind a galloping horse. He is buried in the family cemetery six miles northeast."
