This article discusses the experiences of Russian nurses in World War I. An examination of Russia's sisters of mercy—as Russian nurses prior to 1918 were called—in World War I reveals the significance of women's medical service and exposes the fallacy of the notion of war as a distinctly male experience. Russian women's wartime nursing experiences share many of the features of the male war experience. Although conventional wisdom draws lines of demarcation between the active killing and dying of combat and the passive nurturance and support of nursing, in reality, Russian women's wartime medical service blurred such separations. In many ways, the narratives of female medical personnel mirror those of male combat personnel. The nurses who served in Russia during World War I indicate clearly the variety of ways that women intersected with and were affected by the war and the inadequacies of gendered notions of wartime experience.
