I've copied some of my notes on that company here:

Company “H” of Monroe County “Scotland Invincibles”

William Wallace McMillon. Wounded near Atlanta, Georgia, July 28, 1864. Wounded at Franklin, Tennessee, November 30, 1864; captured there on December 17, 1864. Exchanged at Boulware’s Wharf, Virginia, March 27, 1865.

W. J. Robison. Appointed Captain April 20, 1865; formerly 2nd Lieutenant of this company. Surrendered at Greensboro, North Carolina, May 1, 1865.

Officers and men mustered in Confederate service on September 25, 1861, at Camp Davis, Alabama. Survivors formed Company “H”, consolidated 17th Alabama Infantry Regiment.

We have discussed that battle in some detail on this message board. It has several names, including Ezra Church, the Poor House and Lickskillet Road. The battlefield remained in Federal hands, and Federal reports mention spending much of the following day burying the dead. Federal soldiers had to bury several hundred Confederate dead as quickly as possible due to the heat. I would expect burials to have been in shallow trench graves near where the Confederates died.
