I'm enjoying the quest. I'm digging into the resources I have for the Red River Campaign (TransMississippi territory). I've made an inquiry on the Civil War Project about categorization of specific battles. I don't want to stick a new category up without being assured that it hasn't already been done and I just haven't found it. As for Buck, I'm looking more at the Battle of Sabine Crossroads which lead to the Battle of Mansfield, LA. Sabine Pass, TX seems less and less likely considering where Byrd enlisted and fought. I've seen the other individuals you have listed as well. Carman name goes way back in my lines, too. Classic example of how the war pitted family against family.
