While they were at this point a sudden wind arose, with so great a concussion of thunder and darkness, and a stronger blast than they had yet experienced, and the sea rose so much that the ships could not see one another, except when they were upheaved by the seas, when they seemed to be among the clouds. They hung out lights so as not to part company, for the anxiety and fear which the captain-major felt was the losing one of the ships from his company, so that the seamen would put back to Portugal by force, as, indeed, they had very much such a desire in their hearts.
But the captains took very great care of this, because Vasco da Gama, before going out to Lisbon, when conversing alone with the Jew Zacuto in the monastery, had received from him much information as to what he should do during his voyage, and especially recommendations of great watchfulness never to let the ships part company, because if they separated it would be the certain destruction of all of them.
Vasco da Gama took great care of this, personally, and by means of his servants and relations in whom he trusted; and this they attended to with much greater solicitude after they heard the sailors say that they were many, and the captains only a few single men, and in fact they had in their minds such an intention of rising up against the captains, and by force putting back to Portugal, and they thought that, if it became necessary to arrest them for this and bring them before the King, he would have mercy upon them, and, should they not find mercy, they preferred rather to die there where their wives and children and fathers were, and in their native country, and not in the sea to be eat by the fishes. With such thoughts they all spoke to one another secretly, determining to carry it out, and trusting that the King would not hang them all for the good reasons which they would give him; or else to secure their lives they would go to Castile until they were pardoned. This was the greatest insolence they were guilty of; and so they decided upon executing their plan. In taking this decision they did not perceive the danger of death, into which they were going more than ever.
