In the course of the 20th century, no war looms as profoundly transformative or as destructive as World War II. Its global scope and human toil reveal the true face of modern, industrialised warfare. Now, for the first time, we have a comprehensive, single-volume account of how and why this global conflict evolved as it did. This book is a history of the Second World War that tells the full story of battle on land, on sea, and in the air.
