Hi Robert,
The flag shown in the book is an 1864 issue Hardee flag, it has crossed cannons on the moon, while the battle honors Murfreeboro and Chickamauga are in the blue field. I recently talked to Mr. Hawkins about the image. He says it was a drawing done by a researcher and hoped that it would cause someone to find more information about it. I believe that if they would have recieved a Hardee flag, it would have been a late issue; very similar to the 16th Alabama's flag.
