Of the officers whose names have been mentioned, it is to be remembered that Duarte Barbosa was brother-in-law to Magellan and that Estavam Gomez, who, by returning to Seville on the 6th of May, 1521, did not participate in the conclusion of this memorable voyage, was afterwards sent by Charles V. to seek for the north-west passage, and in 1524 sailed along the coast of America from Florida to Rhode Island, and perhaps as far as Cape Cod. Nothing could have been better arranged than this expedition, for the equipment of which the whole resources of the nautical science of that epoch had been taxed. At the moment of departure Magellan gave his last orders to his pilots and captains, and the code of signals which were to ensure unanimity in manoeuvres, and prevent a possible separation. On Monday morning, the 10th of August, 1519, the fleet weighed anchor and sailed down the Guadalquiver as far as San Lucar de Barrameda, which forms the port of Seville, where the victualling of the ships was completed, and it was the 20th of September before they were really off. Six days afterwards the fleet anchored at Teneriffe in the Canary Archipelago, where both wood and water were taken on board. It was on leaving this island that the first symptoms appeared of the misunderstanding between Magellan and Juan de Carthagena which was to prove so fatal to the expedition. The latter claimed to be informed by the commander-in-chief of the route which he intended to take, a claim which was at once rejected by Magellan, who declared that he was not called upon to give any explanation to his subordinate. After having passed between the Cape de Verd Islands and Africa, the ships reached the shores of Sierra Leone, where contrary winds and dead calms detained the fleet for twenty days.
