A firsthand account recounts the formation and operations of an all-woman medical corps that established and ran hospitals in Paris, Wimereux, and a London military hospital, describing organization, daily surgical and medical practice, administrative duties, nursing and orderly work, and the logistics of supplies, laboratories, and visitor relations. It profiles key leaders, the corps' interactions with military authorities, and the practical challenges of treating wounded soldiers under wartime conditions. Chapters cover hospital openings and closures, staff roles, public support and inspections, and the relationship between professional service and the broader movement for women's opportunities in medicine.
