As to the First Arkansas Mounted Rifles, there is an interesting book written thirty years after the fact by Robert Dacus called "Reminiscences of Company "H", First Arkansas Mounted Rifles" available through Morningstar, I think. It reads like the Sam Watkins "Company Aytch" only Dacus is more bitter and a little bit 'ornerier' than Watkins. It's small but I like it.
