World War II was the largest and most destructive war in history. Some 100 million people fought as combatants across Europe, Africa, and West and East Asia. This series describes why and how the war was fought, and explains its impact on those who lived through it. Japan's early conquests left it in charge of the Pacific region, but U.S. naval power eventually regained the initiative. This book explains how U.S forces fought their way across the vast Pacific Ocean in a series of amphibious landings and jungle battles that eventually brought U.S. bombers within range of Japan itself.
