"In and Out of Rebel Prisons" is a book based on a Lieutenant Alonzo Cooper's diary. During his ten months imprisonment in the South, Cooper kept a complete diary of events which occurred there and gave a reliable account of what came under his personal observation.
"Many books have been written upon prison life in the South, but should every survivor of Andersonville, Macon, Savannah, Charleston, Florence, Salisbury, Danville, Libby and Belle Island write their personal experiences in those rebel slaughter houses, it would still require the testimony of the sixty-five thousand whose bones are covered with Southern soil to complete the tale."
