Throughout history, the development of cannons can benefit one side and hurt the other. A good example of this would be when General Han Shizhong used the huochong,( a type of cannon/firearm), to capture a city in Fujian. Han Shizhong’s side prospered while Fujian was destroyed. An example of a battle would be the Battle of Huangtiandang. In this battle, Han used the new flame throwing cannon technology and captured the whole city of Jurchen for 40 days. These events help prove that in battles, one side usually prospers while the other is destroyed and that cannons cause more harm than good.
