A knight must finish a pledged undertaking before taking a new adventure

A knight must finish a pledged undertaking before taking a new adventure is a rule Don Quixote treats as binding: once his word and faith are committed to an enterprise, he must bring it to an end before beginning another. At the inn, this code checks his impulse to intervene, turning a declared obligation into a practical limit on his actions. The episode also distinguishes that limit from a second restriction on whom a knight may fight, showing how several rules can govern the same moment.

The Pledge and Its Priority

When four travellers arrive, Don Quixote is furious that they ignore his challenge. He would attack them, but reasons that it would be improper to undertake a new enterprise before he has established Princess Micomicona in her kingdom. Rather than follow his anger, he keeps silent and waits to see what the travellers will do. The rule does not make him indifferent: it holds his desire for immediate action in check because he considers an earlier commitment unfinished.

Permission to Aid the Landlord

The rule is tested again when two guests beat the landlord after he demands payment. The landlord’s daughter asks Don Quixote to help, but he says he cannot involve himself in another adventure until he has brought his pledged one to a happy conclusion. He instead asks Princess Micomicona for permission to succour the endangered innkeeper. She grants it, and he arms himself and hurries to the inn-gate. His appeal places the immediate plea for help within the framework of his existing obligation; the scene shows him seeking authorization rather than simply abandoning his pledge.

A Second Limit on Action

At the gate, Don Quixote stops. Although the princess has permitted him to assist, he says it is not lawful for him to draw his sword against persons of squirely condition and calls for Sancho Panza, whom he considers responsible for the defence and vengeance. The landlord continues to be beaten while the women grow angry at Don Quixote’s hesitation. The distinction matters: the unfinished undertaking first delays his response, while the restriction on fighting men of that condition determines how he will act even after permission has been obtained.

Narrative Function

The rule makes Don Quixote’s conduct legible through his own chivalric system, but its application also produces comic friction between his solemn reasoning and the urgent, physical trouble at the inn. He is ready to fight, then holds back for the sake of his pledge; when released to help, he halts again under a different rule. The episode therefore presents knightly obligation not as a single general command to intervene, but as a hierarchy of commitments and restrictions that can complicate the aid Don Quixote intends to give.
