In Fangorn, Aragon, Legolas and Gimli meet Gandalf. He had died, but was sent back to Middle-earth as Gandalf the White, to further help the fight against Sauron. Gandalf tells them that Merry and Pippin are well. They then go to Edoras, the capital of Rohan. Gandalf tells King Théoden that they have to go to war against Saruman. Gríma Wormtongue, a spy and servant of Saruman, is cast out. The people of Edoras, led by Éomer's sister Éowyn, flee to Dunharrow in the White Mountains, while the army of the Rohirrim goes to their fortress at Helm's Deep. Aragorn, Legolas, and Gimli go with the Rohirrim warriors, but Gandalf leaves once more without notice. Saruman sends his army of ten thousand Uruk-hai, Orcs, and Dunland men to Helm's Deep. The next morning Gandalf arrives with another Rohirrim army. They defeat Saruman's army, and win the "Battle of the Hornburg".
