The Asian Military Revolution: From Gunpowder to the Bomb (New Approaches to Asian History) (repost)

Records show that the Chinese invented gunpowder in the 800s. By the 1200s they had unleashed the first weapons of war upon their unsuspecting neighbours. This extraordinarily ambitious book traces the history of that invention and its impact on the surrounding Asian world - Korea, Japan, South East Asia and South Asia - from the ninth through the twentieth century.
