A messenger comes forward and offers them Frodo's mithril coat and his cloak. The messenger tells them that Sauron demands that they retreat to Gondor and pay him tribute to return Frodo alive. Gandalf asks the messenger how Sauron could expect one prisoner to be worth so much. He takes the mithril coat and cloak from him but says that there will be no retreat. The messenger lets loose a hideous cry and the gates of Mordor crash open.
Armies come from behind the hills and pour from the gate.
The men of Gondor leap to battle. Pippin prepares to die as he draws his sword. The swarms of orcs break like a storm on the ranks of Gondor. A great orc falls over Pippin and as he passes out he thinks he hears men yelling about eagles. That came in his tale, long long ago.
