The Torsion Catapult is a siege weapon from the Middle Ages. It was the long-range weapon of William the Conqueror. Horses were normally used to pull the catapult back, giving it more tension than a crank powered or human powered catapult.

The Torsion Catapult went up against Joan of Arc's Siege Cannon. On the field, the catapult was set to hit targets at 50 yards. The objective was to launch projectiles over the wall and strike as many targets as possible. This included guards along the ramparts, and villagers in the "castle courtyard". The crew used four stones and a pig's head, representing Norman soldiers using dead animals to spread the bubonic plague.

The first shot cleared the wall but didn't hit any targets. The second shot used a pig head to spread the plague. The next three rocks hit three targets, one in the village, one in a house and one guard on the rampart (in the head).

While the Catapult could reload faster, the cannon did more damage and the loudness of the blast caused a psychological impact, so the edge went to the cannon.


  • Roman catapults could use hair as a substitute for rope. Roman women could donate their hair to support the construction of catapults.
