Another thing I've learned; many of the men joined the CSA in self-defense. They knew the Union was headed their way and wouldn't know the difference between Union households and CSA. They saw themselves as simply protecting their families from an invading army. When their year's, etc., enlistment was up, if they didn't feel like staying, they went home. Many were disenchanted with the war by that time. Also, the CSA practice of impressment was not taken kindly. (Impressment may not be a good term. They initiated a draft program which was not liked, a'tall!)
Incidentally, my 2gtgrandfather, McSewell HENDRIX, of Geneva Co., Al., was in Murphey's Bn., Al. Cavalry. Would love to know where he was killed, if anyone knows.
God bless the USA and thank God I'm Southern!
