Villafana modelled his plans upon those of the slayers of Julius Caesar. All the conspirators were to approach Cortez in public, and one of them was to approach him with what should purport to be a letter from his father, Martin Cortez, just arrived on a vessel from Spain. The moment he took the letter and began to read it, all were to rush upon him and stab him with their knives. Cortez detected the plot just in time. He personally went with guards to Villafana's apartments and arrested him, while others took the other conspirators into custody. Villafana was put to death, and the others were imprisoned. Then Cortez, with characteristic resourcefulness, turned the incident to account for his own profit, by making it the pretext for continually thereafter surrounding himself with an armed body guard of his most trusted soldiers. Velasquez returned to Santiago to find affairs in a sad plight. Small pox, measles and other epidemics were raging, and disastrous tropical hurricanes had swept the island, destroying crops and buildings. A large proportion of the most efficient men of the island had followed Cortez--and Narvaez--to Mexico. Moreover, Diego Columbus, at Hispaniola, was threatening trouble. It must be remembered that Velasquez had practically flouted Columbus's authority, almost as much as his own had been flouted by Cortez. At any rate, the Admiral had a serious grievance against him, and deemed this a fitting time for calling him to account. Apparently he was further aggrieved because Velasquez would not more fully accept the counsel of Ayllon. At any rate, in the middle of January, 1521, he sent over to Cuba an envoy, to take the place of Velasquez as Governor of Cuba and to investigate the manner in which Velasquez had administered his affairs. This envoy was Alfonso de Zuazo, who thus became the second Governor of Cuba. In this action Velasquez acquiesced; probably because he durst not do otherwise. It would have been a dangerous thing in any circumstances to defy the Admiral; and it would have been superlatively so at a time when Cuba had just been stripped of its ships and its best fighting men. Nevertheless, he pointed out that he himself was still commandant of the fort at Baracoa, and was Repartidor of the natives throughout the island. This latter was in some important respects a more influential office than that of Governor, and it Velasquez held, not by the Admiral's appointment but by virtue of a commission granted directly by the King himself. He could not, therefore, be superseded or interfered with in any way by the Admiral or any of his underlings, nor by anybody short of the King himself. In this he was quite right, and when Zuazo, relying upon Diego Columbus's authority, did infringe upon some of Velasquez's functions and powers, the latter complained to the King, and the King disavowed Zuazo, and severely reprimanded Columbus.
