Once again Samson Carranzo appears, this time at the beach in Barcelona where, in the guise of The Knight of the White Moon, he challenges Don Quixote to battle. Of course, Quixote accepts the challenge and, in the presence of the viceroy and a distinguished company, is roundly defeated. A condition of Quixote's defeat is that he abandon knight errantry for the rest of his life.
In the remaining chapters, Don Quixote and Sancho Panza return to La Mancha, but not before they experience an additional stay with the Duke and Duchess and sundry other humiliating experiences suffered by the ex-knight.
When they arrive home, Don Quixote, apparently broken in spirit, is put to bed. After a long sleep, he declares his name to be Alonso Quixano once more and appears to have regained his reason. Shortly after he denounces chivalry and knighthood, he dies among the lamentation of friends.
