Giant beasts who inhabited Harad and were ridden by the Haradrim, who constructed great towers upon their backs. They were called Mumakil by the Haradrim. Hobbits sang songs about them, and Sam gamgee wanted t0 see one on the quest. They did, but it was marching to War in service of the Haradrim, who were evil and served Sauron. It was shot at by Rangers of Ithilien, who drove it into the woods where it may have lived or perished. More Oliphaunts brought the Haradrim to war in the Battle of Pelennor Fields, where they were ambushed and killed. Haradrim fought in the Battle at the Black Gate, but it is not known whether or not they rode Oliphaunts.
