With grateful thanks to Ciaran Conlan, an Irishman who has a love of WW1 and helps anyone who needs hel. Ciaran helps me a great deal with my research.
During the First World War, Louise was recruited and worked as a secret agent for the British during WW1, using the code name Alice Dubois. She was arrested by the Germans and condemned to death on 16th March 1916.
Louise said “I am French. I would never do anything against my country, my conscience and my honour”. The sentence was commuted to hard labour for life and Louise was sent to Germany, where she died due to pleural abscesses poorly operated upon at St. Mary's Hospital in Cologne on 27th September 1918.
