Maj. Gen Ambrose E. Burnside VS Clement L. Vallandigham

Click to enlarge.. After Burnside's troops arrested Vallandighham and roughly hauled him to Cincinnati to stand trial in a military court he was asked to enter a plea for the charges against him. Vallandigham said: 'This is a military tribunal. I do not recognize this court's authority to try me!"

Another interesting aspect of this story is Clement Vallandigham's accidental death at the Golden Lamb in Lebanon, Ohio.
  John Zimkus historian at the Warren County Historical Society and author of Historical Footnotes of Lebanon, Ohio wrote a colorful account how Vallandigham died. While representing a defendant in a murder case, Vallandigham enacted his view of what occured at the crime scene. He attempted to prove the murdered man actually shot himself while pulling a pistol out of his pants pocket. Thinking that a pistol he was using as a prop was unloaded, Vallandigham pointed it at himself and pulled the trigger. The gun went off, and Vallandigham was mortally wounded.
Clement Laird Vallandigham was buried at Woodland Cemetery in Dayton, Ohio.
