Before his return there came a fleet of seventeen vessels, bearing fifteen hundred men, with arms, munitions, and supplies, under Sancho de Arciniega. Relief was immediately sent to San Mateo and to Santa Elena, where most of the soldiers had mutinied, and had put Stephen de las Alas in irons, and sailed away. Menendez divided part of his reinforcements among his three posts, and then with light vessels ascended the St. John’s. He endeavored to enter into negotiations with the caciques Otina and Macoya; but those chiefs, fearing that he had come to demand reparation for the attacks on the Spaniards, fled at his approach. He ascended the river till he found the stream narrow, and hostile Indians lining the banks. On his downward voyage Otina, after making conditions, received the _adelantado_, who came ashore with only a few attendants. The chief was surrounded by three hundred warriors; but showed no hostility, and agreed to become friendly to the Spaniards. On his return Menendez despatched a captain with thirty soldiers and two Dominican friars to establish a post on Chesapeake Bay; they were accompanied by Don Luis Velasco, brother of the chief of Axacan, who had been taken from that country apparently by Villafañe, and who had been baptized in Mexico. Instead, however, of carrying out his plans, the party persuaded the captain of the vessel to sail to Spain. Two Jesuit Fathers also came to found missions among the Indians; but one of them, Father Martinez, landing on the coast, was killed by the Indians; and the survivor, Father Rogel, with a lay brother, by the direction of Menendez began to study the language of the chief Carlos, in order to found a mission in his tribe. To facilitate this, Menendez sent Captain Reynoso to establish a post in that part of Florida.[894] News having arrived that the French were preparing to attack Florida, and their depredations in the Antilles having increased, Menendez sailed to Porto Rico, and cruised about for a time, endeavoring to meet some of the corsairs. But he was unable to come up with any; and after visiting Carlos and Tequeste, where missions were now established, he returned to St. Augustine. His efforts, individually and through his lieutenants, to gain the native chiefs had been to some extent successful; Saturiba was the only cacique who held aloof. He finally agreed to meet Menendez at the mouth of the St. John’s; but, as the Spanish commander soon learned, the cacique had a large force in ambush, with the object of cutting him and his men off when they landed. Finding war necessary, Menendez then sent four detachments, each of seventy men, against Saturiba; but he fled, and the Spaniards returned after skirmishes with small bands, in which they killed thirty Indians.
