Columbus: Ohio State University Press, 1930. First. Hard Bound. Near Fine / Near Fine. Item #632
"The time has come for an impartial and non-controversial study of prisons North and South during the Civil War. Old hates have cooled..." (Publisher's note.)
Arguably the best compilation of prisoner of war information. Extensive bibliography. Each prison is addressed individually.
Nevins I-193: Best secondary account of military prisons, exhausting most published sources…especially adequate on exchange controversy and war psychosis.
Doubt you can find a better copy!
