Close up of grapeshot from an American Revolution sketch of artillery devices

Grapeshot is a type of anti-personnel ammunition used in cannons. Instead of solid shot, a mass of loosely packed metal slugs is loaded into a canvas bag. Grapeshot can also be improvised from chainlinks, shards of glass, rocks, etc. When assembled, the balls resemble a cluster of grapes (hence the name). On firing, the balls spread out from the muzzle at high velocity, giving an effect similar to a shotgun but scaled up to cannon size.

Grapeshot was devastatingly effective against massed infantry at short range. It was used to quickly savage massed infantry charges. Cannons would fire solid shot to attack enemy artillery and troops at longer range (although the Shrapnel round was invented to increase the effect of grape shot at a distance), and switch to grape when they or nearby troops were charged.

Grapeshot was largely replaced by canister shot during the early 19th century, with the cloth bag being replaced with a wood-sealed metal canister, guided by a wooden sabot. This gave improved range, more controllable dispersal, and allowed the shot to be safely fired at higher velocity.

Conflicts in which grapeshot was famously and effectively used include:

• The noted pirate Bartholomew Roberts (popularly known as Black Bart) was killed by a blast of grapeshot from H.M.S. Swallow on the 10th February 1722.
• Battle of Culloden - 1746, Jacobites under Bonnie Prince Charlie vs British forces under the Duke of Cumberland
• Battle of Guilford Court House, when Cornwallis ordered two Grapeshots to be fired into the middle of a battlefield, where hand-to-hand combat between the British and Rebels was taking place.
• 13 Vendémiaire - Napoleon, then a brigadier general during the later stages of the French Revolution, famously dispersed a Royalist mob on the streets of Paris with a "whiff of grapeshot" on 5 October 1795. He was rewarded with the command of the Army of Italy in 1796, and his victories at the battles of Lodi, Castiglione, Arcola and Rivoli provided a springboard for his military and political ambitions.
• During Irish Rebellion of 1798, widely used by British forces against Irish rebels, notably in battles of New Ross, Arklow and Vinegar Hill
• Battle of Borodino, 1812 (Prince Mikhail Kutuzov (Russia) v Napoleon Bonaparte (France) ).
• In Victor Hugo's novel Les Misérables, grapeshot was the weapon used against the barricades in the 1832 insurrection in Paris.
• British commander Sir Edward Pakenham was fatally wounded while on horseback by grapeshot fired from the earthworks during the Battle of New Orleans.

Since the passing of muzzle loaded cannon, and the introduction of the fixed round, grape has been replaced by canister or case round, where a brass cartridge contains the shot.
