Wall guns were large caliber smooth-bore muskets that were used in the 16th through 18th centuries by defending forces to break the advance of enemy troops. They were too heavy to be fired from the shoulder and so were usually rested on window ledges or low walls, hence the name. They were also known as Hackbuts, a name originally given to early medieval hand cannon. Many were fitted with a barrel hook to absorb shock. Some of these weapons had multiple barrels which enabled volleys to be fired much faster than a normal single shot wall gun.
Wall Guns were used in India as early as the 17th century and there is a Burmese source from the late 15th century mentioning the use of "cannon and muskets" by the defenders of the besieged town of Prome. There are examples of later wall guns fitted with bipods.
A wall gun's barrel could be over 54 inches (140 cm) in length with a bore of at least 1 inch (2.5 cm). This made them more accurate than the standard flintlock or matchlock musket. George Washington acquired several wall guns during the American War of Independence; tests showed that they were capable of hitting a sheet of common writing paper at 600 yards (550 m). Wall guns were part of the standard equipment of some artillery pieces at that time.
A breech-loading wall gun was issued to the French army in 1819 for the defense of towns. Improved caplock versions were introduced in 1831 and 1842, as were muzzleloading versions. Bolt action wall guns firing metallic cartridges were used in India and China in the late 19th century.
When HMS Espoir captured the Genoese privateer Liguria on 7 August 1798, Espoir's captain, Commander Loftus Otway Bland, catalogued Liguria's armaments as: 12 long 18-pounders, four long 12-pounders, 10 long 6-pounders, 12 long wall-pieces, and four swivel guns. Mentions of wall guns are rare in such enumerations; what is more common are mentions of the swivel gun. These, though, were shorter than wall guns, did not have stocks, and generally fired 1 or 1½-pounder round shot.
