For decades, a major piece of World War II history has gone virtually unwritten. China was the fourth great ally--partner to the United States, the Soviet Union, and Great Britain--yet its drama of invasion, resistance, slaughter, and political intrigue remains little known in the West. In this book, made possible through access to newly unsealed Chinese archives, Rana Mitter unfurls the story of China's World War II as never before and rewrites the larger history of the war in the process.
