when was the gun first used in war
History of the firearm The direct ancestor of the firearm is the fire lance, a black-powder–filled tube attached to the end of a spear and used as a flamethrower (not to be confused with the Byzantine flamethrower); shrapnel was sometimes placed in the barrel so that it would fly out together with the flames.[3][4] The earliest known depiction of a gunpowder weapon is the illustration of a fire-lance on a mid-10th century silk banner from Dunhuang.[5] The De'an Shoucheng Lu, an account of the siege of De'an in 1132 during the Jin–Song Wars, records that Song forces used fire-lances against the Jurchen.[6]
