This book explores the contributions of Italian Americans employed by the Office of Strategic Services (OSS) during World War II. Italian Americans fluent in Italian language and customs became integral parts of intelligence operations working behind enemy lines. These units obtained priceless military information that significantly helped defeat the Axis. They parachuted into frozen mountains tops to link up with Italian guerrilla units in northern Italy or hovered in small patrol torpedo boats and row boats across the Mediterranean Sea in pitch black darkness to destroy railroad junctions.
