Have you seen "Of Savage Fury: The Battle of Richmond, Kentucky," by Anthony Hawkins?
There's a color image of the battle-flag of the 30th (later redesignated 25th) Arkansas Infantry, with Farmington and Richmond battle honors. Also a color image of the battle-flag of the 1st Arkansas Infantry, which is mis-identified by the author as the flag of the 1st Arkansas Mounted Rifles. Also color images of Union and Confederate flags from other states.
There is a comprehensive list of casualties. I helped Mr. Hawkins with the Arkansas casualty lists, so I can vouch for their accuracy. And I assume that he put as much care into his research of casualties from other states.
Includes transcriptions and excerpts from soldiers' letters, as well as official reports and newspaper accounts of the battle.
The book was privately printed in 2004. ISBN 1-933304-15-4.
