This chapter presents an analysis of soldier-writers of the Great War. It focuses on an overview of a singular phenomenon closely linked to literary history and more generally to the political, cultural, social and economic history of the Great War. The war itself and the form that it took account for the development in most of the warring nations of this new category of soldier-writers. Daily writing, of letters or personal diaries, was certainly not understood as a literary gesture, but it favoured the emergence of front literature. The death of writers and poets was an essential element in the legitimation of war literature. Repeated references to their sacrifice reinforced the writers contribution to the war effort and gave to the cause a quasi-universal dimension. The chapter also discusses a transnational history of war literature and the soldier-writers.
