They are the forgotten members of the Greatest Generation: the animals who kept up morale, rushed machine gun nests, and even sacrificed themselves picking up live grenades. In this illustrated history, the author of Sgt. Reckless: America's War Horse tells the heartwarming stories of the dogs, horses, mules—and even one cat—who did their bit for the war effort, including Cher Ami, the pigeon who nearly died delivering a message that saved American troops from friendly fire; Olga, the horse who braved shattering glass to do her duty during the London Blitz; Judy, the POW dog who helped her beloved human survive brutal Japanese prison camps; and Smoky, the Yorkshire terrier who did parachute jumps and laid communications wire through a pipe so small that only she could navigate it.
