This chapter concentrates on the early months of the war, and delving into autobiographical testimonies looks more closely at the suffering and fate of enemy aliens. The chapter then describes the implementation of the policies adopted in the early months and deals with expulsion, forced repatriation and deportation. It then addresses the internment of civilians, which was one of the major novelties that the belligerent countries introduced in the European war. The chapter follows the spread of concentration camps throughout Europe and the British and French Empires, the internment gender and generational dimensions, and the beginning of the humanitarian activities that the mass internment of enemy aliens triggered. The third part of the chapter deals with another crucial novelty that concerned the property rights of the enemy aliens. States at war sequestered and confiscated their assets as part and parcel of the economic war they waged. The internment and sequestration of enemy property led to enormous growth in the apparatuses of the state. And this meant that state involvement in the lives of civilians increased disproportionately.
