The result was that the King in March, 1565, appointed him to be Adelantado of Florida, and captain-general of the Spanish fleet in that part of the world specially commissioned to guard the coasts and ports of the Indies. That was six months before Osorio became governor of Cuba. The commission of Menendez bade him to "guard the coasts and ports of the Indies." Very well. Cuba was certainly one of the Indies. Therefore he was commissioned to guard the ports and coasts of Cuba. Being familiar with Cuba, and recognizing its very great importance, he naturally deemed the guarding of that island as one of the very first of his duties. Mazariegos did not demur, since he was himself soon to retire from the governorship. But when Osorio came to Havana six months later, and found Menendez in command of all that pertained to harbor and coast defence, there was trouble. Osorio asserted his rights and authority as governor of Cuba. Menendez replied with an assertion of his as captain-general "to guard the coasts and ports." The first clash came because Menendez interpreted his jurisdiction as extending to fortifications on land as well as to shipping; which we must regard as extreme if not overstrained. He assumed direction of the garrison of Havana, and had two hundred men sent thither from a large detachment which was sent to Florida. As La Fuerza was not yet finished sufficiently to accommodate them, houses were hired to receive them. Osorio was not notified in advance that they were coming, or that they had arrived; and after they were there they refused to regard his authority but took orders solely from Baltazar Barreda, a captain whom Menendez had assigned to their command. Presently Barreda took charge of La Fuerza and began moving thither the artillery, including the four pieces which Osorio had brought with him from Spain. Osorio remonstrated, saying that the fort was not yet sufficiently completed for use. Barreda defied his authority, and was sustained by Menendez, who happened to be in Havana at the time. The governor yielded, for the time. But as soon as Menendez was out of the city he clapped Barreda into jail, after a violent physical struggle, and appointed Pedro de Redroban to the command of the fort in his stead. News of this reached Menendez and he hastened back and released Barreda. As for Redroban, he and half a dozen of his men fled to the woods, in well-founded fear of Menendez.
