This book goes deeper into some aspects of the First World War, which, the author believes, the world must know and remember, not only as a memorial of men's courage in tragic years, but as a warning of what will happen again if a heritage of evil and of folly is not cut out of the hearts of people. It presents the reality of modern warfare not only as it appears to British soldiers, but to soldiers on all the fronts where conditions were the same. Presenting the tragic record of the battles, it reveals the truth of the war as revealed in the minds of men out of their experience. It argues that some new system of relationship between one people to another and some new code of international morality must be explored so that another massacre of youth must be prevented..
