This title examines the experiences of Americans in Europe during the First World War prior to the U.S. declaration of war. Key groups include volunteer soldiers, doctors, nurses, ambulance drivers, reporters, diplomats, peace activists, charitable workers, and long-term American expatriate civilians. What these Americans wrote about the Great War, as published in contemporary books and periodicals, provides the core source material for this volume. Author Kenneth D. Rose argues that these writings served the critical function of preparing the American public for the declaration of war, one of the most important decisions of the twentieth century, and of defining the threat and consequences of the European conflict for Americans and American interests at home and abroad.
