Prince Carlos, probably because of his uncle's position, and also due to the friendship they had for years, confided to John of Austria his plans to flee Spain and to travel towards the Spanish Netherlands from Italy. Prince Carlos needed John's help to acquire a galley that would ferry him to Italy. In exchange for his assistance, the Prince had promised John the Kingdom of Naples. John told the Prince that he would give him an answer, and went immediately afterwards to the El Escorial to report it to the King.
