I've seen books on East Tennessee Confederates. I've seen little to no info on men from predominately Confederate West Tennessee who served in union regiments.

My gg grandfather, Robert Lee Williams unlike most of my ancestors, served in Bradfords Battalion 14th (aka 13th) Cavalry Co. E.

I've always been curious as to what motivated him to serve the north when most of the family fought south. Could he have been conscripted or was is his choice to fight north ?

Thanks for any info.
