Anderson served in the
Princess Christian's Army Nursing Reserve in
Bloemfontein during the
Second Boer War and was mentioned in dispatches in 1901, subsequently being awarded the Royal Red Cross (RRC) award. On return to the United Kingdom, she maintained links with military-reserve nursing services. In 1908, she was invited to join the national advisory committee at the
War Office for the newly formed
Territorial Force Nursing Service (TFNS). In 1910, she was elected to the committee of the City and County of London. The sisters employed to work for Anderson were all chosen because they could speak the
Hindustani language. In 1916, the hospital was taken over by the
New Zealand Medical Corps. At this point, Anderson joined
Queen Alexandra's Imperial Nursing Service (Reserve) (QAIMNS(R)), training as a military matron at the
Queen Alexandra's Military Hospital in London, following which she was posted to
Bagthorpe Military Hospital,
Nottingham, as matron. She resigned from military-nursing service in 1919 and returned to Glasgow. ==Death==
