My great-grandfather, Andrew Link, enlisted in the Confederate Army on 1 Oct 1862 in Catawba County NC. I know that he was in the 46th NC Infantry, Company K as a private. At some time he was captured and spent time at Point Lookout as a POW prior to being released after signing allegiance to the US. His daughter indicated to me that he was really sick during this time though he survived and lived to be an old man. What info can anyone provide on his service, capture, pension, etc?
