What alias does Samson Carrasco use when he defeats Don Quixote?

Samson Carrasco uses the alias Knight of the White Moon when he defeats Don Quixote. The battle takes place on the beach at Barcelona in Part Two of Cervantes’s novel and becomes the turning point that forces Don Quixote to abandon knight-errantry.

Carrasco is a young bachelor and a friend of Don Quixote’s household. He first disguises himself as the Knight of the Mirrors, but Don Quixote defeats him in that encounter. Later, Carrasco returns under the new identity of the Knight of the White Moon and challenges Don Quixote again.

The second contest is carefully arranged around a promise: if Don Quixote loses, he must return home and cease his adventures for a year. After his defeat, he honors the terms and travels back toward La Mancha with Sancho Panza. The White Moon should not be confused with the earlier Knight of the Mirrors, or with the Lions episode, another famous adventure from the novel.
