Frank, the 1st Arkansas Battalion Reserve Cavalry has got to be the most obscure outfit ever. There is no reference to it in the Compiled Service Records or the O.R. I first became aware of it several years ago in a handful of references in various Goodspeed's South Arkansas biographical sketches. Later, I ran across a few pension applications from men who served in the battalion. Based on this very limited information, I think that Lieut. Col. Henry D. Flippin's battalion was comprised of four to six mounted companies from Bradley, Dallas and Ouachita counties; mustered into service sometime in late 1863 (possibly in State, rather than Confederate, service); and may have been peripherally involved in the Camden Expedition actions. The companies may have been originally organized as home guard companies. That's the extent of my knowledge of this battalion -- not much to show for 20 years of looking. My hope is that someone out there is sitting on some as yet unknown information about this unit.
