Good luck finding hardly any kind of records about the prisoners at Camp Douglas. Most were deliberetly destroyed to coverup the true amount of deaths that occured. I've gone through every channel myself trying to find my GGGrandfather, Sam Graham and his stay at Camp Douglas. I have found his exsistance from Tenn CSA Cav and his oath of allegence and enlistment into the 3rd Illinois Cav. His stay at Camp Douglas can not be found.
