More than 59,000 American nurses served in the Army Nurse Corps during World War II. Nurses worked closer to the front lines than they ever had before. They served under fire in field hospitals and evacuation hospitals, on hospital trains and hospital ships, and as flight nurses on medical transport planes. The skill and dedication of these nurses contributed to the extremely low post-injury mortality rate among American military forces in every theater of the war. Overall, fewer than 4 percent of the American soldiers who received medical care in the field or underwent evacuation died from wounds or disease.
