First invented in China, cannon were among the earliest forms of gunpowder artillery, and over time replaced siege engines âamong other forms of ageing weaponryâon the battlefield. In the Middle East, the first use of the hand cannon is argued to be during the 1260 Battle of Ain Jalut between the Mamluks and Mongols.The first cannon in Europe were in use in Iberia by the mid-13th century.estern cannon during the 19th century became larger, more destructive, more accurate, and could fire at longer range. One example is the American 3 in (76 mm) wrought-iron, muzzle-loading rifle, or Griffen gun, used during the American Civil War, which had an effective range of over 1.1 mi (1.8 km).
