Han Shizhong
The first documented battlefield use of gunpowder artillery took place on 29 January 1132, when Song General Han Shizhong used huochong to capture a city in Fujian. The world's earliest known hand cannon is the Heilongjiang hand cannon dated 1288, which was found in Mongol-held Manchuria. In his 1341 poem, "The Iron Cannon Affair", one of the first accounts of the use of gunpowder artillery in China, Xian Zhang wrote that a cannonball fired from an eruptor could "pierce the heart or belly when it strikes a man or horse, and can even transfix several persons at once."
