An estimated 50 million people perished in World War II. Millions across the globe fled war zones to be replaced by soldiers of all creeds and backgrounds. The war changed the world. As technology raced ahead, this was matched by political change, the final end of old empires and the growth of new superpowers. This atlas is a companion volume to The Viking Atlas of World War I. It traces the development of all the major campaigns of World War II, with eye-witness accounts aimed at bringing to life the human experience of war. Detailed introductions aim to clarify the political and strategic conditions that led to war, together with text and map annotations that offer insights into military operations and tactics.
