Below is an article from The Alleganian (Cumberland, Maryland) dated August 24, 1864. It describes a battle near Atlanta that took place on August 6, 1864. The article describes the 100th Ohio but then calls out the 200th Ohio's flag, which is probably a typesetting error. I can not find a reference to the 200th Ohio being in Georgia, and it appears that regiment near took the field.

The article also describes the 8th Tennessee's flag being captured.
