artillery, chain shot is a type of
cannon projectile
A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in ...

A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A c ...

Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). Th ...

shrouds
Shroud usually refers to an item, such as a cloth, that covers or protects some other object. The term is most often used in reference to '' burial sheets'', mound shroud, grave clothes, winding-cloths or winding-sheets, such as the famous S ...

Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—''standing rigging'', including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are ...
of a target ship.
When fired, after leaving the muzzle, the shot's components tumble in the air, and the connecting chain fully extends. In past use, as much as 1.8 m (6 ft) of chain would sweep through the target. However, the tumbling made both bar and chain shot less accurate, so they were used at shorter ranges.

Chain shot was sometimes used on land as an anti-personnel load. It was used by the defenders of
Magdeburg in May 1631 as an anti-personnel load, which, according to counselor
Otto von Guericke
Otto von Guericke ( , , ; spelled Gericke until 1666; November 20, 1602 – May 11, 1686 ; November 30, 1602 – May 21, 1686 ) was a German scientist, inventor, and politician. His pioneering scientific work, the development of experimental me ...

first English Civil War
The First English Civil War took place in England and Wales from 1642 to 1646, and forms part of the 1639 to 1653 Wars of the Three Kingdoms. They include the Bishops' Wars, the Irish Confederate Wars, the Second English Civil War, the Ang ...

siege of Clonmel in 1650, against the
76th Regiment of Foot in India in 1803, and by the French against the Dutch at the
Battle of Waterloo.
The military usefulness of chain shot died out as wooden sail-powered ships were replaced with armored steam ships—first among navies, and then among commercial fleets—which do not have rigging to serve as proper targets for chain-shot. Additionally, the conversion of naval armament from

In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the proj ...
,
breech-loaded guns further slowed the production of new chain shot ammunition; the chain would damage barrels (degrading maximum range, and further degrading effective range by degrading accuracy), and the new breech loading guns and their ammunition were meant to be effective against armored vessels as well as wooden sailing vessels.
In modern times, the effect is replicated in
