In and Out of Rebel Prisons

About the author
A. (Alonzo) Cooper was an American Civil War memoirist born in 1830 and deceased in 1919. He is best known for In and Out of Rebel Prisons, published in 1888, a personal account of his experience as a Union officer held in Confederate prisons.
Library of Congress catalog records identify him as the author of that book, and the work itself has remained in circulation through major public-domain archives. Readers still return to it for its direct, eyewitness perspective on captivity during the war, especially its descriptions of prison life, endurance, and the human cost of the conflict.
Reliable biographical details beyond the dates attached to his name were limited in the sources I could confirm here, so it is safest to remember him chiefly through the memoir he left behind.
