Book excerpt: "Soldier mortals would not survive if they were not blessed with the gift of imagination and the pictures of hope," wrote Confederate Private Henry Graves in the trenches outside Petersburg, Virginia. "The second angel of mercy is the night dream." Providing fresh perspective on the human side of the Civil War, this book explores the dreams and imaginings of those who fought it, as recorded in their letters, journals and memoirs. Sometimes published as poems or songs or printed in newspapers, these rarely acknowledged writings reflect the personalities and experiences of their authors. Some expressions of fear, pain, loss, homesickness and disappointment are related with grim fatalism, some with glimpses of humor.
