This might help. It is from a manuscript written by John Witherspoon DuBose and is in the Alabama Dept. of Archives and History. John M. Hamrick was member of Co. I, 36th Ala. Infantry. It fits the time line of his death on July 4, 1863. "On the night of July 4, we bivouacked on Battle Creek. On July 5 and 6, the brigades of Generals Clayton and Liddell occupied in succession the position of rear guard."This is all that is found touching the brigade in the action. This was a master stroke by which he turned the flank of General Bragg, and drove him out of his two strongly fortified positions, giving the possession ofMiddle Tennessee to the Federals, with but slight loss to either army. General Rosecrans reports his loss at 85 killed, 462 wounded, 13 missing; a total of 560. He says, "The killed and wounded of the enemy is unknown, but we took 1,634 prisoners, of which 59 were commissioned officers. We captured six pieces of artillery, many small-arms, considerable camp equipage, and large quantities of commissary and quartermaster's stores." O.W.R.
