Interview with Smith Thornton Vian, Oklahoma By Field worker, James S. Buchannan, September 16, 1937
The most serious gun battle in the history of Vian occurred in 1892 . It was the result of a difficulty between my brother, Bill Thornton, and Jesse Landrum. It occurred in Thompson's store and my brother cut Landrum with a knife before I could separate them. Later in the evening, Landrum, seeking revenge, came to Thompson's store where my brother and I were. When I saw him coming I told my brother that Landrum had threatened his life and he had better watch him. My brother saw Landrum approach the front of the store and not having a gun on him, he took a gun from the holster of a friend, Jim Girty, who was in the store. He fired one shot at Landrum as Landrum jumped back from the door. There were other shots fired outside the store by someone, and when the shooting ceased, George Starr, who was also in the store, heard someone groaning out in the street. I took the oil lamp from the counter in Thompson's store, and George Starr took the gun that my brother had, and we went out to see who was shot, as George thought it was his brother Joe Starr. To our surprise we found Isaac Girty, a friend, shot and dying. As George Starr and I stood by Girty, George with Jim Girty's gun in his hand, and I with the lamp in my hands, Landrum approached and said "George Starr killed Isaac Girty for nothing." He was implying that Starr had killed Girty, when we all knew that Starr had not fired a shot, and besides, Starr and Girty were friends. The instant Landrum made the remark, Starr and Landrum both began shooting and fired two shots each. Landrum turned and said "Come on boys he's got me," walked a few steps, sat down and fell over dead. Starr sank down where he was standing and asked me to pull his boots off as his feet were getting cold. I stepped back to set the lamp down and stumbled over something, and discovered a white man by the name of Boots Hanson lying behind me dead, supposedly accidentally shot by Landrum. I set the lamp down and pulled George's boots off. Others gathered and around by that time and we carried Starr, Landrum, Girty, and Hanson into the blacksmith shop nearby. All were dead except Starr, who died about two hours later. I then took Thompson's lamp back to the store.
