Prince Rilian's Rescue ends the prince's enchanted captivity through a decision that is perilous precisely because the rescuers cannot know its outcome. When the captive invokes Aslan, Jill Pole, Eustace Scrubb, and Puddleglum recognize the final sign and choose to free him; Rilian then destroys the Silver Chair and recovers his identity as Caspian's son. The rescue turns obedience to the signs into a concrete act, and releases both the prisoner and the truth of who he is.

Background and the decisive sign

The rescue reaches its crisis when the bound Knight calls on Aslan and charges the travelers to set him free. The appeal transforms the question before them: they had agreed not to release him, and he warns that he may become their mortal enemy once unbound. Yet his invocation matches the sign they have been instructed to follow. Their uncertainty is not resolved by any assurance that the choice will be safe; the central test is whether they will act on the sign despite not knowing what will follow.

Puddleglum makes that distinction explicit. He does not claim that everything will turn out well, and allows that the Knight could be the death of them. Aslan, he points out, told Jill what to do, not what would happen. The travelers therefore face a choice between the protection of their earlier promise and fidelity to the instruction they have repeatedly struggled to follow. Jill accepts the danger, and the group prepares to release the captive.

Releasing the prisoner

Puddleglum and Eustace Scrubb approach the Knight with their swords drawn and begin cutting the cords in Aslan's name. The action is deliberate rather than a misunderstanding or an accidental release: the travelers identify the words as the sign and obey it consciously, despite their fear. Their release of the prisoner is the immediate consequence of trusting the instruction when its consequences remain unknown.

Freed, Rilian crosses the room in a single bound, takes up the sword that had been removed from him, and turns first against the Silver Chair. His weapon cuts through the chair, leaving twisted fragments on the floor. Its destruction is accompanied by a flash, a sound like small thunder, and a foul smell. The chair is not merely broken furniture: Rilian calls it an engine of sorcery and identifies it as an instrument his captor might use on another victim. His first act as a free man thus prevents its reuse as well as ending its hold over him.

Identity restored

After destroying the chair, Rilian surveys his rescuers, and the earlier wrongness in his face has vanished. He recognizes Puddleglum as a genuine Narnian Marsh-wiggle, a recognition that makes clear that his knowledge of Narnia has returned along with his freedom. Asked whether he had forgotten Narnia while under the spell, he confirms that this and the other enchantments are over.

Rilian then identifies himself publicly: he is Prince Rilian of Narnia, and Caspian the great King is his father. The declaration resolves the central uncertainty surrounding the captive Knight. The apparent stranger whom the travelers have found in the underground chamber is the missing prince they came to seek, and the man who seemed to threaten them becomes their deliverer in the larger political sense: the rightful royal identity concealed by enchantment has been recovered.

Consequences and significance

The rescue changes the scene's governing value from confinement and uncertainty to freedom and recognition. The decisive action does not begin with certainty about the prisoner's character or the safety of the travelers; it begins with their decision to honor the final sign. That decision permits Rilian to act for himself, destroy the instrument of his captivity, and name his lineage. The episode therefore makes obedience consequential without making it a guarantee of personal safety: Puddleglum's warning that events might go badly remains part of the choice they accept.

Rilian's regained identity also confirms the importance of the quest. The travelers' purpose was to find the prince, but the discovery alone could not restore him; he had to be released, and the chair that bound him had to be destroyed. In the scene's sequence, the appeal to Aslan prompts recognition of the sign, obedience brings physical release, and the destruction of the chair clears the way for Rilian to recognize both Narnia and himself. The reunion with his proper identity is thus both the personal outcome of the rescue and the revelation that the mission has reached its goal.
