Military success in war was contingent on men sustaining a determination to fight. Persuading men to continue fighting or returning them to combat after illness or injury depended on maintaining their morale. The use of female nurses in upholding this resolve was integral to the war effort. The chapter explores the value of the presence of women in hospital wards and in social environments on active service overseas. It considers the occasional antipathy of military authorities and male colleagues to the location of female nurses in war zones. However, it is argued through the provision of expert clinical care, domestic acumen and the use of their ‘female-selves’, nurses were able to salvage men in readiness to return to battle. Nursing sisters thus created a space for themselves in frontline duties. However, the chapter argues, this was not without its difficulties. As single, white women in far-flung places, this position situated nurses in a liminal place between the respectable European colonial wife and the ‘biohazardous’ local women. The chapter acknowledges these difficulties, but also demonstrates how the nurses negotiated their way through these contradictions to their advantage and for those in their care.
