Young Brunette Girl Shows Off On The Cannon

Joseph Needham suggests that the proto-shells described in the Huolongjing may be among the first of their kind. The Chinese also mounted over 3,000 cast bronze and iron cannon on the Great Wall of China, to defend themselves from the Mongols. The weapon was later taken up by both the Mongol conquerors and the Koreans. Chinese soldiers fighting under the Mongols appear to have used hand cannon in Manchurian battles during 1288, a date deduced from archaeological findings at battle sites.
In the 1593 Siege of Pyongyang, 40,000 Ming troops deployed a variety of cannon to bombard an equally large Japanese army. Despite both forces having similar numbers, the Japanese were defeated in one day, due to the Ming advantage in firepower. Throughout the Seven Year War in Korea, the Chinese-Korean coalition used artillery widely, in both land and naval battles.
