I am researching my ggrandfather, Anfin ERSLAND. He was from Story county, Iowa and served in an unknown unit. He was captured and according to my father, who heard his stories as a young boy, was sent to Andersonville. He had his leg amputated there and survived to return to Iowa after the war. My father's most vivid memory of what his grandfather told him was that he had survived in large part because he had befriended a Confederate guard. They apparently shared a passion for chess and also were both Masons. Apparently this guard would give my ggrandfather extra food now and again, that he would share later with his mates. If anyone could point me in the right direction to find out more information on my ggrandfather, I would appreciate it. Thank you John Tendall
