D. John of Austria never saw Prince Carlos again, or heard from the lips of D. Philip the slightest allusion to his unhappy son. These sad events drew the brothers together, and it must be confessed that D. Philip was at this time a real father to D. John. At the beginning of May, 1568, he announced to D. John that the hour had come for him to take command of the galleys of Cartagena, first to meet and escort the fleet coming from the Indies, and then to clear the coasts of the Mediterranean of corsairs. These pirates went far inland with the greatest effrontery, and it was known that their real leader and protector, Selim II, was having galleys and engines of war constructed with the intention of taking them to the Ionian Sea. The news of the expedition prepared for D. John filled the young nobles with enthusiasm, as formerly the unlucky Maltese one had done, and the flower of them hastened to enlist under his banner. D. Philip was pleased to see his brother's influence, which might be so useful to his political ends, and, in order to stimulate and inspire warlike ardour in these illustrious volunteers, divided the galleys among parties of four, giving the command of each to a captain, chosen from among them, who afterwards were commonly called "cuatraldos." As lieutenant to D. John, D. Philip named no less a person than D. Luis de Requesens, Knight Commander of Castille, who was ambassador at Rome, and, as secretaries, Juan de Quiroga, already acting as such, and Antonio de Prado, a man of great parts, who was afterwards a statesman under Philip III. Among the brilliant band of volunteers who followed D. John the most distinguished were D. Martin de Padilla, who was afterwards Governor of Castille and Captain-General of the Ocean; D. Pedro de Cervellon, D. Juan de Zúñiga, afterwards Conde de Miranda; D. Francisco de Rojas, afterwards Marqués de Poza and President of the Treasury; the brothers D. Jerónimo and D. Antonio de Padilla, D. Luis de Córdoba, D. Juan de Gúzman, D. Alonso Portocarrero, D. Rodrigo de Benavides, D. Mendo Rodriguez de Ledesma; D. Hernando de Gamboa, D. José Vázguez de Acuña, D. Hernando de Prado, D. Pedro Zapata de Calatayud, and D. Hernando de Zanguera. All these gentlemen accompanied D. John to take leave of the King, who was at Aranjuez, and were received with much attention by all the Court. On saying good-bye D. Philip handed to his brother, for his guidance, the following document, written by his own hand, notable for the great maxims for the rule and conduct of a prince which it contains, and for the fraternal solicitude which it shows on the part of Philip II towards his brother:
