This postcard, published in the midst of World War I in 1915, represents the unity of nurses across nations. In war time, many military nurses cared for wounded soldiers regardless of country of origin thus setting military nurses and other field medics apart into an army of their own.

This independence was partially out of necessity—there was little time to identify who was who on the battlefield—and partially out of a sense of moral duty. The moral and ethical duty of medical professionals to remain independent and impartial, to work outside their biases, remains an important aspect of the nursing profession. Those who dedicate themselves to healing dedicate themselves to healing all people.
