Gandalf's Return as the White Rider

Gandalf's return as the White Rider is the hinge upon which the fortunes of the Free Peoples turn in the War of the Ring. When Aragorn, Legolas, and Gimli encounter an old beggar in Fangorn Forest, they mistake him for Saruman and prepare to shoot; but the figure casts aside his grey rags to reveal white garments beneath, and Legolas recognizes him with a cry of "Mithrandir!" The wizard who fell into the abyss in Moria has been reborn, clothed in white, and his reappearance reunites the scattered Company and redirects the war against Sauron.

The Revelation in Fangorn

On the morning after the three hunters camp at the eaves of Fangorn, an old man in tattered grey approaches them. Gimli urges Legolas to shoot, believing it is Saruman, but Aragorn counsels patience. The old man climbs the rock-wall with surprising agility, and when he stands before them, a gleam of white is glimpsed beneath his rags. Gimli springs forward with his axe, but the old man is too quick: he leaps to a rock, casts off his hood and grey cloak, and stands revealed in shining white robes. Legolas shoots an arrow high into the air, where it vanishes in a flash of flame, and cries out "Mithrandir!" The others gaze in wonder: his hair is white as snow, his eyes bright and piercing, and power radiates from him. Aragorn speaks first: "Gandalf! Beyond all hope you return to us in our need!" The wizard replies, "Yes, that was the name. I was Gandalf," and then, picking up his grey cloak, adds, "Yes, you may still call me Gandalf." He lays his hand on Gimli's head, and the Dwarf looks up and laughs, saying, "But you are all in white!" Gandalf answers, "Yes, I am white now. Indeed I am Saruman, one might almost say, Saruman as he should have been."

The Transformation and Its Meaning

Gandalf explains that he has passed through fire and deep water since they parted on the Bridge of Khazad-dûm. He tells them of his long fall with the Balrog, their fight far under the earth, and the final battle on the peak of Celebdil, where he threw down his enemy and then lay naked upon the mountain-top, "forgotten, without escape upon the hard horn of the world." There Gwaihir the Windlord found him and bore him to Lothlórien, where he was healed and clothed in white. He reveals that he has since striven with the Dark Tower and that the Ring has passed beyond his help—Frodo has resolved to go alone to Mordor, and Sam has gone with him. He also brings messages from Galadriel: to Aragorn, a warning about the Paths of the Dead; to Legolas, a caution about the Sea; and to Gimli, a greeting and the instruction to "lay thine axe to the right tree."

The Reunited Company and the New Course

With Gandalf's return, the three hunters gain a new leader. He summons Shadowfax, the chief of the Mearas, who comes at his call, and together they ride to Edoras to confront Théoden, who has been weakened by Wormtongue's counsels. Gandalf heals the king, casting off the shadow of Saruman, and sets the Rohirrim on the path to war. The White Rider then rides to Helm's Deep, arriving at dawn with Erkenbrand's men to turn the tide of battle. His reappearance restores hope to the Company and to all the Free Peoples, marking the moment when the war against Sauron shifts from desperate flight to organized resistance.
