Linda, I am working with the Arnold Family Foundation on the last three of the planned wayside exhibits for DeValls Bluff (funding in part by the Arkansas Humanities Council). Coincidentally, one of the panels deals with the many troops who passed through DVB (I think that only Helena may have seen more). So, based on Dyer's Compendium, I think this might be a comprehensive list of Yanks who moved through there at various times.
