Cannon

A Cannon is truely a powerful weapon. Once the gun powder is ignited and forcing the iron cannonball on its way, destruction in the one thing that is sure to follow. However, despite being so destructive, the downside is that canons are huge and hard to move and need a constant supply of gun poweder (from Powder kegs) and cannonballs. That makes it only useful for fortresses and ships.

Cannons existed since the time of Ultima I, but they were always installed on ships and could be used to blast away foes. Only beginning with Ultima V was it possible to use cannons on land as well.

According to Vetron's Guide to Weapons and Armour, a Cannon has a damage power of 90.
