In Minas Tirith they meet Faramir, who tells them of his meeting with Frodo. The next day Faramir goes off to defend the old city Osgiliath, but the city falls, and so do the outer defenses of Minas Tirith. During the retreat Faramir is badly wounded. Minas Tirith is besieged by the armies of Mordor, led by the Witch-king, the leader of the Nazgûl who (it was said) could not be killed by any man. Denethor goes insane and burns himself, and almost also kills the injured Faramir, but this is prevented by Pippin and Gandalf.
