Ayllon seems to have been vested with no actual authority over Velasquez. He merely tried to dissuade him from executing his purpose. He urged him to content himself with sending one or two vessels on to Mexico, with a summons to Cortez, to return or at least to abandon his pretensions of independence and to acknowledge the authority of Velasquez; under penalty of being reported to the King as a contumacious rebel. The rest of the expedition, he suggested, might be used in explorations elsewhere. Above all, he pleaded with Velasquez not to go to Mexico himself, but to return to Santiago, where his presence was sorely needed. Velasquez yielded to these entreaties so far as to abandon personal leadership of the expedition. He made Panfilo de Narvaez leader in his stead, and then returned to Santiago. Ayllon went along with Narvaez, to keep the peace. The result was that soon after landing in Mexico, Narvaez was wounded and made captive by Cortez, and practically all his men, with their stores, munitions, arms and ships, who had been sent out to subdue Cortez, became loyal followers of that resourceful conquistador. In fact, we may judiciously reckon that Cortez owed his success in the conquest of Mexico to the reenforcements which he thus received from the expedition which had been sent against him.
Later, it is true, some members of Narvaez's party became a source of serious peril to Cortez. This was at the beginning of the year 1521, after the death of Montezuma and the _noche triste_, and at the time when Cortez was planning to return to the city of Mexico as its conqueror. A number of Narvaez's men entered into a conspiracy to assassinate Cortez, and at their head was one Villafana, who had been a very close friend and earnest partisan of Velasquez. Because of that relationship, it was suspected by Cortez that the man had been incited to undertake the crime by Velasquez himself. Of this there was, however, no proof, and no attempt was made to fasten responsibility or odium upon Velasquez; which we may be sure would have been done had any real ground for it been discovered. By interesting coincidence, the conspiracy was made, detected and punished at the very time when, as we shall see, Velasquez was being removed from the Governorship of Cuba.
