When the First World War broke out, the suffragettes suspended their campaigning and joined the war effort. For pioneering suffragette doctors (and life partners) Flora Murray and Louisa Garrett Anderson that meant moving to France, where they set up two small military hospitals amidst fierce opposition. Yet their medical and organisational skills were so impressive that in 1915 Flora and Louisa were asked by the War Ministry to return to London and establish a new military hospital in a vast and derelict old workhouse in Covent Garden's Endell Street. That they did, creating a 573-bed hospital staffed from top to bottom by female surgeons, doctors and nurses, and developing entirely new techniques to deal with the horrific mortar and gas injuries suffered by British soldiers. The story of 'Endell Street' provides both a keyhole view into the horrors and thrills of wartime London.
