An English Woman-Sergeant in the Serbian Army - Flora SANDES

Flora Sandes was the only British woman officially to serve as a soldier in World War I. Initially a St. John Ambulance volunteer, she traveled to Serbia, where, in the confusion of war, she was formally enrolled in the Serbian army. While the Serbian Army was regrouping in Corfu, Ms. Sandes returned to England to recuperate and publish these memoirs.(Summary from Wikipedia)
