A great company of Hill-trolls from Gorgoroth fought at the Battle of the Morannon. Since the battle took place during the day, these Hill-trolls may have been of the Olog-hai strain. The Hill-trolls struck down many Men of Gondor with their heavy hammers. The Troll-chief wounded Beregond and would have bitten his throat, but Pippin Took stabbed the Troll with his sword of Westernesse, which he later called "Troll's bane." After the battle, Gimli found Pippin alive under the Troll's heavy carcass.
