During the First World War, she trained as a nurse at St Bartholomew's Hospital, London, later joining Queen Alexandra's Imperial Military Nursing Service (QAIMNS) in 1917, which she rejoined in 1937. Jones was mentioned in despatches, while serving in Palestine. In 1938, she returned to Britain where she was appointed the Principal Matron at the War Office.

In 1939, the Second World War was declared and Jones mobilised more than 1000 QAs to France to serve with the British Expeditionary Force (BEF). Along with the British Army the QAs retreated from Dunkirk on 26 May 1940; all were safely returned to England. In July 1940, aged 44, Jones was promoted to Matron in Chief of the QAIMNS.

As Matron in Chief of the QAIMNS, Jones wrote the introduction to Grey and Scarlet, a collection of letters sent to her by Nursing Sisters of the Queen Alexandra's Imperial Military Nursing Service and Territorial Army Nursing Service from France, Iceland, Tobruk, Sudan, Eritrea, Gibraltar, Greece, Middle East, North Africa, Malta, Malaya and Singapore.^[3]
