"The Germans called them 'the Black Devils.' The Allies ultimately credited them with turning their fortunes around in the toughest year of World War II. They were the men of the First Special Service Force. Europe, 1942. Something drastic needed to be done to defeat Hitler. A secret meeting led to the creation of an unprecedented unit made up of men from the United States and Canada, nearly two thousand soldiers superbly skilled in the ways of the wilderness - mountain climbing, skiing, and arctic survival. From the Black Devils' arduous training in the harsh terrain of Helena, Montana, to their bold assault on a prime German position high in the Italian alps, A Perfect Hell features unforgettable portraits of men who achieved the impossible, including Colonel Robert T. Frederick, whom Churchill called the greatest fighting general in history; New Mexico-born Mark Radcliffe, the first Allied soldier to enter Rome; and Joe Glass and Lorin Waling, legendary scouts and best friends, who were interviewed exclusively for this book. A Perfect Hell is the story of inspired leadership, victory in the face of insurmountable odds, and unquestioning camaraderie."-- from the publisher.
