[World War I]
After the United States entered the war on 6 April 1917, many Utahns were directly affected as relatives and friends joined the armed services or were drafted. Approximately 21,000 Utahns saw military service; of these, 665 died and 864 were wounded. Of the 665 deaths, 219 were killed on the battlefield or died from wounds received in action; 32 died of accidental causes; the remaining 414 died from disease and illness. Of the 10 percent of the Utahns who served were of foreign birth or were members of U.S. ethnic or racial minorities. A number of Utah women, including eighty registered nurses, served during the war as nurses, ambulance drivers, clerical and canteen workers.
