The wall piece or wall gun was a type of smoothbore firearm used in the 16th through 18th centuries by defending forces to break the advance of enemy troops. Essentially, it was a scaled-up version of the army's standard infantry musket, operating under the same principles, but with a bore of up to one-inch (25.4 mm) calibre. These weapons filled a gap in firepower between the musket and the lightest artillery pieces, such as the swivel gun. This sort of weapon may also be found described as an amusette, rampart gun, or Hackbut, a name originally given to early medieval hand cannon.
