This is the first book to attempt to measure and describe the full scale of civilian deaths during the world wars, from all causes, including genocide, starvation, aerial bombardment, and disease. While nations went to great lengths to record military casualties, they often didn’t count or deliberately obscured civilian deaths. Getting the numbers right is important. It reveals much about the true human costs of the wars, the nature of modern warfare, and the failure of efforts to stop civilian casualties. It also makes it possible to argue with those who try to deny, minimize, or exaggerate wartime savagery.
