The admiral was ready to sail from Messina in June 1284 with forty armed galleys, besides smaller vessels. With this force he gained one of his most brilliant victories. He shaped a course for Naples, and formed in line of battle about two bow-shots from the mole, as a defiance and a challenge. Charles of Anjou was intriguing at Rome, but his eldest son and heir was in Naples, and ready to accept the challenge. His followers were not equally willing. The name of Roger de Lauria was one of dread, and the Neapolitans held back. The younger Charles was furious. He embarked himself, and shame obliged his officers to follow. A fleet of thirty-eight galleys and many smaller vessels was got ready, and came forth to encounter the terrible Roger de Lauria. A battle raged in the Bay of Naples from nine in the morning until dusk, but as usual victory attended on the banners of the admiral of Aragon. The Prince’s galley was surrounded and boarded by En Roger himself, to whom Charles, after a long and brave resistance, was forced to surrender. The admiral said to the usurper’s son: ‘You must do two things. If not, be sure that the death of Conradin will be avenged.’ The Prince answered that he would do anything to save his own life. ‘The first thing,’ continued the admiral, ‘is that you order the daughter of King Manfred to be released from her prison and brought safely on board my galley.’ This demand was complied with. The long-imprisoned princess was taken from the Castel del Novo and brought safely on board the flagship, where the admiral joyfully received the sister of his Queen, kneeling before her and treating her with all honour and respect. ‘The second thing,’ continued he to Charles, ‘is that you deliver up to me the town and castle of Ischia.’ This also was done. The victorious fleet then returned to Messina with the released princess and the captive prince. Never had there been seen such rejoicings in Messina as greeted the admiral on his return. The Queen and her sons went on board the galley to receive their long-imprisoned relation. It was a most affecting scene. The two sisters embraced each other, weeping for joy mingled with sorrow. Since they had seen each other their father Manfred and their cousin Conradin had been killed; their mother and all the rest of their family had died in prison. The crowd of spectators was equally moved when the sisters, with the young princes, walked together from the landing-stage to the palace. Charles was sent to the castle of Matagrifone. The Sicilian Parliament met at Messina soon afterwards and decreed the death of the younger Charles, as a reprisal for the death of Conradin. He would certainly have been executed if the young Prince En Jayme had not interfered, preferring the more generous course of returning good for evil. Charles was confined for some time in the castle of Cefalu, and eventually removed, by order of King Pedro, to a prison at Barcelona.
