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.
