4. Onagers were cranked down to launch a rock or heavy object.

5. Trebuchets were the ultimate castle- destroying machine! Heavy counterweight was placed in a swinging box, which, when released, would sling the weapon (rock, dead and diseased bodies, etc.) into or over the castle wall. This was the first weapon that could take a castle down!
