At that moment, when all hope seemed lost, Frodo put on the One Ring, revealing to Sauron that Frodo was inside Mount Doom, and the Ring was in peril. He immediately summoned the Nazgûl from the battle to intercept Frodo; the army of Mordor, bereft of Sauron's attention, was thrown into disarray. Gollum bit the Ring off Frodo's finger. As Gollum celebrated, he fell with the ring into the Crack of Doom, destroying Sauron's power. The Nazgûl perished. Barad-dûr, the Black Gate and the Towers of the Teeth collapsed as their foundations were built with the power of the Ring. Sauron perished; his gigantic shadow formed in the sky and reached out in wrath, but was blown away and his spirit was left forever bodiless and impotent.
