I did a little more research and came up with the following:

James M./W. Brotherton enlisted February 28, 1862 as 1st Sergeant, Co. C, 39th Georgia Infantry, he was elected 2nd Lieutenant November 7, 1862, wounded at Baker's Creek, May 16, 1863, died of wounds three days later on May 19.

A fellow member of his regiment Pvt. James Russel Horn, Co. H of the 39th Georgia provides us with the following:

The following letter was provided by Valette Randall randallv@airmail.net of her ancestor Private James Russell Horn. He was killed on 22 July 1864 during the Battle for Atlanta.

A member of my ggrandfather's regiment, Pvt. William Bratcher, Co. B, 43rd Tenn. Inf. was left wounded at Edwards Depot Hospital May 16, 1863 and captured by Union forces the next day.

Edwards Depot/Station is located approximately 15 miles East from Vicksburg, and the Champion Hill battle site some 18 miles East.

Further investigation reveals that "Dr. Estus, a native of the town [Edwards], turned his home into a hospital for southern soldiers during the Civil War."

I would suggest that you might query those I mentioned before with this additional information.

Good Hunting,
