A simple mangonel illustration

A 'mangonel was a type of catapult or siege machine used in the medieval period to throw projectiles at a castle's walls. A catapult is any one of a number of non-handheld mechanical devices used to throw a Projectile a great distance without the aid of an explosive substance—particularly various A siege engine is a device that is designed to Break or circumvent City walls and other Fortifications in Siege warfare. A castle is a defensive structure seen as one of the main symbols of the Middle Ages. The mangonel had poorer accuracy than a trebuchet (which was introduced later, shortly before the discovery and widespread usage of gunpowder). A trebuchet or trebucket is a Siege engine that was employed in the Middle Ages either to smash Masonry Walls or to throw Gunpowder is a an explosive mixture of Sulfur, Charcoal and Potassium nitrate (also known as saltpetre/saltpeter that burns rapidly producing volumes The mangonel threw projectiles on a lower trajectory and at a higher velocity than the trebuchet with the intention of destroying walls, rather than hurling projectiles over them. It was more suited to field battles. Mangonels shot heavy projectiles from a bowl-shaped bucket at the end of the arm. The bucket could launch more rocks than a sling; this made it different from an onager. The onager was a post-classical Roman Siege engine, which derived its name from the kicking action of the machine similar to that of an Onager (wild ass In combat, mangonels hurled rocks, burning objects (fire pots, vessels filled with flammable materials that created a fireball on impact), or anything else readily available to the attacking and defending forces. The more unusual types of projectile included dead, and often partially decomposed, carcasses of animals or people, used to intimidate, demoralize, and spread disease among the besieged. This tactic often proved effective. The short supply of food, which was often of low quality or rotting, combined with the cramped living space of the defenders, poor hygiene, and vermin infestations provided an ideal scenario for the spread of disease. It should be noted, however, that the mangonel's principal role in battle, particularly medieval battle, was to knock down a castle or city's walls and infrastructure, not to kill/demoralize troops. Its unpredictable, yet powerful strikes were best suited to hitting broad, non-moving targets such as buildings or walls. Mangonels might also have thrown burning sand at enemies, the hot sand would enter openings in armor, leading to painful burning or death.

In addition to laying enemy castles to waste during sieges, the mangonel was also eventually adapted to provide cover for troops on the battlefield. This tactic was first devised and employed by Alexander the Great.

Despite its low accuracy, the versatility and maneuverability of the mangonel ensured that it was the most popular siege catapult used during the medieval period.
