That would be great to have a website for this unit.
There were also many men from Greene Co, TN in the unit.
I am researching the Payne men that were in Company K.
One of the units' famous expolits was participating in 'Stoneman's Raid' into North Carolina at the end of the war.
A good book on the unit is 'History of the 13th Regiment TN Volunteer Cavalry USA', by Scott and Angel.
E-mail me if you would like any more info on the 13th.
