145th Field Artillery regiment departs Utah for duty in the "Great War" (World War I). Nearly all of its 1,300 to 1,500 officers and enlisted men are LDS, so the unit is nicknamed "the Mormon regiment." Seventy's president B.H. Roberts serves in the regiment as a chaplain. He is the first active general authority since 1846 to participate in a U.S. war and is among the first three Mormons to serve as U.S. military chaplains. There are 665 deaths (including missing-in-action) among the 21,000 Utahns (primarily Mormons) who serve in World War I.
