Howdy,
You might want to look at www.fortunecity.com/victorian/pottery/1080/ for the Confederate Order of Battle at Peachtree Creek and Atlanta. The 2nd is listed for both, however; I have read somewhere that Cleburne's Division may not have been heavily committed at Peachtree Creek (?).

Army of Tennessee (Gen John Bell Hood)

Hardee's Corps (LGen William Hardee)

Cleburne's Div (MGen Patrick Cleburne)

Govan's Brigade (BGen Daniel Govan)

2nd Ark Inf (Col E. Warfield)
