Cannonballs

Deadly iron cannonballs are necessary to fuel the numerous cannons seen throughout the realm. When propelled at high speed through the use of powder kegs, these destructive metal spheres are capable of sinking most waterborne craft, or blasting down stubborn gates and doorways.

Ship-mounted cannons have existed since Ultima I, only in the time of  Ultima V did land-based cannons (and piles of cannonballs) appear.

Trivia

 * Through Ultima V, cannons had unlimited shots -- even when not placed next to a supply of cannonballs.


 * Only in Ultima VII the player can pick up the cannons and used elsewhere.


 * The acquisition of custom-made steel cannonballs fashioned by Andrew Carnegie was an essential component of finishing  Martian Dreams, allowing access into Argyre.
