Then, on the morning of December 7, 1941—everything changed. Japanese fighter planes dropped bombs on the U.S. naval base at Pearl Harbor in Hawaii, killing 2,400 and wounding another 1,200 Americans. The repercussions of the air attacks included the internment of 120,000 people of Japanese ancestry, sixty-two percent of whom were U.S. citizens. The act of aggression also affected the military. American-born soldiers of Japanese descent were discharged or segregated within their branch of the armed forces.
