'''[[:Category:Middle Ages|Medieval]]''' weaponry included a large number of '''[[Catapult|Catapults]]''' such as the '''[[Mangonel]]''', '''[[Onager]]''', the '''[[Ballista]]''', and the [https://en.wikipedia.org/wiki/Trebuchet '''Trebuchet'''] which was brought over to Europe in the 4th century AD.

The [https://en.wikipedia.org/wiki/Trebuchet '''Trebuchet'''] was a large machine, about 30m high consisting of a long beam attached by an axle suspended high above the ground by a strong frame and base.

The long beam was winched down and the sling loaded with a large stone typically, but could be almost anything. When released, the [https://en.wikipedia.org/wiki/Counterweight '''Counterweight'''] would cause the arm quickly to swing upwards and the long sling also to rotate and release the load at the end of the movement. This combined motion would impart considerable speed on to the sling and an average load of 50-100kg could be hurled 300m or more.

Two types of [https://en.wikipedia.org/wiki/Trebuchet '''Trebuchet'''] were used. A '''Counterweight Trebuchet''' had a fixed weight either fixed to the short arm of the beam or a '''Traction Trebuchet''' in which weights were loaded into a basket hanging from it and troops would pull it down with ropes to assist and/or control the release.

They were used mainly to throw stones, fire pots and even rotting corpses over the fortifications to cause destruction and create chaos inside the walls.
