I,too, would greatly appreciate getting the scans of what you mentioned. My e-mail is firstname.lastname@example.org.
My Greatgrandfather, E.C. Hallmark, rode with the 13th TEXAS Cavalry. I am not sure if it was the Battalion or the Regiment.
I have documents that will answer that question, but they are in TEXAS and ,at this time , I am in Missouri. I will check next time I am home.
I thought that my greatgrandfather's unit only served in the northeast part of TEXAS. I don't remember where I got that info. From my Dad, I think.
Also, he told me that the 13th that Greatgranddad served in, was dismounted after their first year. That unit was formed in 1862 and continued as a unit until the Wars' end.
