Hill troll

Hill-trolls are closely related to cave-trolls and mountain-trolls and are minions of Sauron in J.R.R. Tolkien's The Lord of the Rings.

They are usually found in the Mountains of Shadow and the Mountains of Ash, the two mountain ranges bordering Mordor.

They were used in the War of the Ring during the siege of Minas Tirith, mostly in the pulling of heavy objects and loading the enormous stones into the catapults.

The armies of the West fought "Hill-trolls out of Gorgoroth" at the Morannon; since the battle took place in direct sunlight, these hill-trolls are inferred to have been Olog-hai.
