Grond (battering ram)
Grond was a battering ram, used by Sauron's forces to destroy the Great Gate of Minas Tirith during the Battle of the Pelennor Fields. The ram was "a hundred feet in length", and its head was of black steel, made to resemble a wolf. It is told that Grond had been induced with "spells of ruin". During the Siege of Gondor, Grond was drawn to the Great Gate by "great beasts" and was wielded by mountain-trolls.
 Portrayal in Adaptions
- The ram took the shape of the whole wolf's body, rather of just its head. Gothmog called it in after a smaller battering ram proved futile against the great gates.
