The letters between military surgeon Georges Duhamel and his wife Blanche lay forgotten in a family attic for 75 years. Recently rediscovered, they reveal a poignant love story set against the backdrop of the First World War. In 1914, Blanche Duhamel moved to the frontline capital at Amiens, from where the lights of the trenches were visible, in order to be closer to her husband. Previously unseen film footage shows how business and pleasure continued alongside scenes of suffering as British and colonial troops came and went from the city.
