Among the inspirational women of the First World War on my list is Lise Rischard, an 'ordinary' housewife from Luxembourg. Officially neutral in WW1, the people of Luxembourg had suffered greatly during the wars that ravaged Europe in the previous years. Lise's son by her first marriage - Marcel Pelletier - was a member of the French Olympic Team sent to the Olympic Games held in Stockholm in 1912.
During a visit to her son, who was in the French Army and in Paris before being sent to the Front, Lise was recruited to help the Allied cause. Her story is amazing as she travelled from her home in Luxembourg in the area held by the Germans via Switzerland to Paris, which remained a free city during WW1, and then set up a network to provide vital information to the British.
I mention Lise in "No Woman's Land" but you can find out the whole amazing story in the book 'The Secrets of Rue St. Roch' by Janet Morgan (London: Allen Lane, 2004).
