I can't imagine how they must have looked for those letters! Several things about the letters intrigue me. First, the fact that the U.S. Gov't allowed them to use CSA stamps to mail their letters. Those letters had to go through the U.S. Postal Service. Second, how did the people back home know where to send letters? I suppose they didn't until they received a letter, but do you know if families were given information about POW's and where they were in prison?
I ordered a badge through a Sons of Confederate Veterans Camp in Texas as a descendant of a confederate prisoner. On the back I was able to have them inscribe information about my ancestor, his company and the date/place he was captured. They also sent a certificate in his name stating where he was held prisoner (all info that I provided). It's a wonderful addition and I am proud to own it. I haven't seen them advertise the badges in the last couple of Confederate Veteran magazines, so wonder if they're still making them.
