The Council of Elrond decided to send the Ring to Mount Doom to destroy it and Sauron's power. It was carried into Mordor by two Hobbits, Frodo Baggins and Sam Gamgee; they entered by the pass of Cirith Ungol. In the War of the Ring, Sauron attempted to storm Minas Tirith, the capital of Gondor, but was defeated by Gondor and Rohan in the Battle of the Pelennor Fields. The victors sent an army to the Black Gate to distract Sauron from the Ring. He responded by emptying Mordor of its armies, sending them to the Black Gate. As a result, the plain of Gorgoroth was left almost deserted and Frodo and Sam were able to travel across it to Mount Doom. During the Battle of the Morannon, the One Ring was destroyed in Mount Doom, along with Sauron's power, Barad-dur, and the morale of his armies. This ultimate defeat of Sauron ended the Third Age. Gorgoroth became empty as its Orcs fled or were killed. The land of Núrn was given to Sauron's freed slaves.
