Once Aslan Susan, and Lucy are in the courtyard, Aslan begins to breathe on each statue. The girls cannot figure out what Aslan is doing until they notice what happens to the stone lion, the first statue that Aslan breathes on. A ripple of gold appears and the statue transforms into a real lion. Throughout the courtyard all the statues come alive, including the loyal Narnians that the Witch had enchanted—the talking animals, centaurs, satyrs, and even a giant. Next, Aslan, Susan, and Lucy storm the dungeons, where they find more stone prisoners, including the faun Tumnus.
Once Aslan restores all of the statues, Aslan leads all of the creatures as a troop to help Peter in battle. Peter's army had been faltering against the Witch's troops, and was desperately in need of reinforcements. When Aslan's troops arrive, they see Peter and the Witch dueling furiously. Peter wields the sword that Father Christmas gave him and the Witch holds her stone knife. Aslan quickly interrupts the fight. Aslan leaps upon the Witch and kills her instantly.
Once Aslan's new army joins the fight and the Witch dies, the battle is brief. Lucy immediately notices that Peter has become stronger and seems older. Peter recounts the fight to Aslan and tells him that they would have been decimated if it had not been for Edmund's intelligence. Peter's army was losing against the Witch, because she would turn Peter's army into stone. Edmund furiously fought the Witch and realized that he should smash her wand instead of attacking her directly. The destruction of her wand had restored some hope in Peter's army, but Edmund was terribly wounded in the attack.
Peter leads Aslan, Susan, and Lucy to where Edmund lies on the ground, mortally wounded. Aslan reminds Lucy of the magic healing cordial that Father Christmas gave her, and Lucy eagerly pours a few drops down Edmund's throat. Lucy cannot stay to see if the cordial works because there are so many other wounded people. When Lucy finally returns, Edmund is well again and looks better than ever. Edmund has lost the sullen, spiteful look that he had had ever since he began attending school. Edmund returns to his real old self and Aslan knights him.
Aslan crowns the children as the kings and queens of Narnia, and then Aslan disappears. Mr. Beaver explains that Aslan is expected to leave and then return whenever necessary. The children reign long and faithfully. They enact fair laws and keep Narnia peaceful and harmonious. Naturally, they grow up to become adults. Peter is known for his valor and strength, and is called King Peter the Magnificent. Susan is known for her beauty and grace, and is called Queen Susan the Gentle. Edmund is famous for his intelligence and fairness, and is called King Edmund the Just. Lucy is known everywhere by her gaiety and high spirits, and she is called Queen Lucy the Valiant.
One day, after the Pevensies have ruled over Narnia for many years, the now middle-aged Faun Tumnus speaks to them about the White Stag. The White Stag is fabled to grant wishes to whoever catches him, and he has been spotted in Narnia. The Pevensies immediately embark on a hunt and are drawn into Lantern Waste, the wood where the lamppost stands, and where they entered Narnia many years before. There, they find the door through which they originally entered Narnia. The lamppost engenders strange feelings in the four of them, because they can't quite remember what it is, or where they've seen it before. They continue to seek the White Stag, but all at once they find themselves tumbling out of the wardrobe. Suddenly the Pevensies are children again and Mrs. Macready is still in the hall. The children tell the whole story to the Professor, who assures them not to worry. The Professor says that they will return to Narnia again someday, though not through the wardrobe. He explains that they will find other ways into Narnia and will have many more adventures there.
