"Of the approximately 115,000 American dead in the Great War, only about 52,000 died of battlefield wounds. More than 200,000 became more or less seriously wounded. Some 60,000 soldiers and sailors died of disease, mainly the complications of the global pandemic flue (influenza).
During the war over 4,355,000 American men and women served in the armed forces. At the end of the war 1,950,000 Americans were actually fighting in France and Flanders. One in five was foreign-born and one in four was functionally illiterate."
