Mangonel

A mangonel was a type of catapult or siege engine used in the medieval period to throw projectiles at a castle's walls. A mangonel had poorer accuracy than a trebuchet (which was introduced later, shortly before the discovery and widespread usage of gunpowder). 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.
