The entry of the United States into the First World War in late 1911 found Herbert Hoover at a crossroads. Three years earlier, he had been a successful mining engineer in London. Then, as the war intensified in Europe, Hoover founded and led the Commission for Relief in Belgium, which provided desperately needed fuel to more than nine million Belgian and French citizens trapped between the German army of occupation and the British naval blockade.National Review has called this book a magisterial work of scholarship on one of our least-known presidents, and an important era in American history.
