Seeking info on incident involving 2LT William H. McMillan of Clinch's regiment, 4th GA Cavalry who was shot in the back and killed, purportedly by a drunken LT named Webb from a Louisiana command, near “Boughton” (probably Bowdon in Carroll County) GA on 4 November 1864 at a “grog shop” after a verbal exchange between one of the 4th GA’s company commanders and the Louisianan over the captain having ordered some of the 4th GA’s men away from the establishment.

Specifically, I hope to ID the LA officer involved and establish the outcome WRT subsequent court-martial and punishment, if any.
