Wow, how wonderful to own an artifact of the 1st Arkansas Cav.. Quite a rare find. You must be proud. I would be. I'll check out the book and take the flag information into consideration. Thank you so much for your help. My GGGgrandfather was Ptolema Philadelpious Brown of Company L. Served in the Battle of Prairie Grove as well as I can determine and later served for a time as Head Cook of the Regimental Wagon Yard in Fayetteville (Leading hash tosser for the muleskinners).
