As most of us know, fragging is a term coined in Vietnam to describe grenades or "stray" shots directed to an unpopular superior. Braxton Bragg, who later led the Army of Tennessee, had a lit shell rolled into his tent when he was a captain of artillery during the Mexican-American War. Here's an attempted fragging effort by one Union soldier against his lieutenant:
The bullet whizzed over us, but at the same moment Orr got onto his knees, turned around and fired at me. That would have certainly settled my carier [career] had not Charles Buck, at the moment Orr pulled the trigger, with a quick move of his arm pushed the rifle upward exclaiming: 'Orr, what are you doing?!' The bullet whizzed close over my head.
The lieutenant took Orr's rifle and cartridge box for his own use and had a guard posted over Orr to prevent him from further attempts. He wrote Orr up to the Colonel who supported a court martial which would certainly result in his execution. The Colonel deferred the outcome to the lieutenant who forgave Orr on account of his wife and child.
