Thanks for having me. I am from East Texas, near Tyler Texas, the home of the largest POW camp west of the Mississippi river during the civil war. My dear friend passed away and I acquired his civil war collection which included the attached photographs. I'm trying to identify the two men in the attached photos. Heritage Auction advised one of the men is a Confederate Naval Officer and believes the second may also be Confederate Officer. However they did not know who they were. Can anybody help me identify these two men? Thanks.
