Flora Sandes was a part of an ambulance unit that left for Serbia in 1914 to try to aid the humanitarian crises there. Sandes joined the Serbian Red Cross and worked in an ambulance for the Second Infantry Regiment of the Serbian Army. In 1915 Sandes struggled to get to the front, enrolling as a private by General Milos Vasic. She quickly advanced to Corporal. She later received the highest decoration of the Serbian Military, the Order of the Karadorde’s Star, and was promoted to Sergeant major. At the end of the war, she was commissioned as an officer, making her the Serbian army’s first female and first foreign officer. She was also the only British woman to serve as a soldier in WWI.
