This is a detailed study of some 150 unpublished and never before seen images of soldiers of the American Expeditionary Force (AEF) and the Army of Occupation taken in France and Germany during and after World War I. As opposed to the stateside training camp photos and formal portraits taken on return to the USA, this is an in-depth look at what the AEF looked like as they were actively engaged in the business of making the world safe for democracy. These images cover every rank and grade of soldier in the AEF from General Pershing to fresh-faced privates, and every occupational specialty from infantryman to cook. Details of uniforms and equipment, locations, times, and places have been painstakingly researched for each image.
