The Return of the King: Being the Third Part of the Lord of the Rings · Chapter 14
The Destruction of the Ring
Sam carries the failing Frodo up Mount Doom. They face Gollum; inside the Sammath Naur, Frodo claims the Ring, but Gollum's struggle sends it—and himself—into the Crack of Doom. Mount Doom erupts; Sauron's power collapses.
Outcome
The Ring is destroyed; Sauron's realm falls; the Nazgûl perish; Frodo and Sam are rescued by the Eagles.
