Thank you Brent Cox, for an important contribution to understanding the 19th (sometimes called the 9th) Tennessee Calvary and, in particular, the life of its leader, Colonel Jacob Barnett Biffle. I'd reached the end of the Internet in research for my third novel, when I came across your publication.
Published in November 1991, Cox's 48 page report, is well annotated and coil bound. If you don't mind your information coming off of a copy machine--personally, I don't care, as long as as it answers my questions, is well documented and complete--you'll find Cox's treatment of the life and military career a helpful contribution to your research or reading. I needed a quick reference to Biffle's recruitment of southern sympathizers and conscripts in western Tennessee. I also needed a description of the cavalry's movements in Tennessee during the war. I hoped for better details, than I'd found in my search, on Biffle's death in Texas. I found all three in this short reference work.
Cox's preface reads: "I would like to express thanks to the descendants of Colonel Jacob Barnett Biffle. Harold, Jake, and Olin Biffle have been a clear inspiration in the writing of this paper. To them, I extend special thanks and would like to express to them personally, 'that it is an honor to know each of you.' I would like to thank Dr. Lonnie Maness at the University of Tennessee at Martin for suggesting I write on Colonel Biffle, and for his deep interest he has placed in me as a student. As I am studying to get my degree, he inspires me and has made it possible for my continuing struggle."
I've known a few historians in my professional career--some of them armchair and others academic. I don't know anything about Brent Cox and where he's ended up after writing this paper, but I appreciate and recommend his contribution.
