Andrew Carroll spent three years traveling throughout the United States and around the world to seek out the most powerful and unforgettable letters ever written during American wars.

Behind the Lines is the result of that extraordinary trip and represents the first book of its kind: a dramatic, intimate, and revealing look at warfare as seen through the personal correspondence of US and foreign troops and civilians who have experienced major conflicts firsthand. From handwritten missives penned during the American Revolution to e-mails from Afghanistan and Iraq, Behind the Lines captures the full spectrum of emotions — exhilaration, fear, devotion, despair, courage, heartache, patriotism, rage, and even humor — expressed in times of war.
