This is the story of American volunteer pilots who risked their lives in defense of Britain during the earliest days of World War II—more than a year before Pearl Harbor, when the United States first became embroiled in the global conflict. Based on interviews, diaries, personal documents, and research in British, American, and German archives, the author has created a colorful portrait of this small group who were our nation’s first combatants in World War II.<br><br>As the author’s research shows, their motives were various: some were idealistic; others were simply restless and looking for adventure. And though the British air force needed pilots, cultural conflicts between the raw American recruits and their reserved British commanders soon became evident.

They saw action and suffered casualties in both England and France, notably in the attack on Dieppe.
