What is the name of the bachelor who disguises as a knight to bring Don Quixote home?

The bachelor who disguises himself as a knight to bring Don Quixote home is Samson Carrasco. He is a learned bachelor from Don Quixote’s village and one of his acquaintances.

Carrasco first attempts to defeat Don Quixote while disguised as the Knight of the Mirrors, also called the Knight of the Wood in some translations. His plan is to win a joust and use the conditions of the challenge to make Don Quixote abandon knight-errantry and return home. Don Quixote defeats him, however, so the scheme fails.

Carrasco later returns in another disguise as the Knight of the White Moon. This time he defeats Don Quixote in Barcelona and requires him to give up his adventures for a year. Bound by his promise, Don Quixote travels home with Sancho Panza. The defeat contributes to the collapse of his imagined chivalric identity, and he eventually regains his ordinary name, Alonso Quixano.

A common mix-up is to identify Pedro Alonso, a neighbor who helps after an early adventure. Pedro assists Don Quixote, but Samson Carrasco is the bachelor who becomes the disguised rival knight.
