This book is about how people behaved during the German occupation of France during the Second World War, and more specifically about how individuals from different social and political backgrounds recorded and reflected on their experiences during and after these tragic events. The book focuses in particular on the concepts of treason and sacrifice, as they affected the behaviour of individuals and groups and their relationship to the nation state. An introductory overview, discussing problems of representation, moral issues and the nature of collaboration and resistance, is followed by contextualised case studies in the areas of politics, daily life, civil administration, paramilitary action, literature and film. The figures examined are chosen not only because of their representative or even iconic nature but also because most of them left a record expressing their own vision of the occupation. This is very much an interdisciplinary study, linking political, historical, moral and cultural ideas.
