Disappointed in their expectations from Hinojosa, the soldiers consulted how to manage their intended rebellion under another leader, and agreed to kill Hinojosa and to elect Don Sebastian de Castilla as their commander-in-chief; and their design was carried on with so little regard to secrecy that it soon became publickly known in the city of La Plata. Several persons of consideration therefore, who were interested in the peace of the country, communicated the intelligence to Hinojosa, advising him to take precautions for his security, and to banish these people from his government. One Hondegardo a lawyer was particularly urgent on this occasion; and offered, if Hinojosa would appoint him his deputy for one month, that he would secure both him and the city from the threatened danger of insurrection; but Hinojosa had so much confidence in the power of his office, and the influence of his vast wealth and reputation, that he despised every thing that he did not see with his own eyes, and neglected all their warnings. Being unable to persuade the governor to listen to him, and as the soldiers still proceeded in their rebellious designs, and threw out many threatenings against the governor, Hondegardo prevailed on the guardian of the Franciscan convent to intimate to the governor that he had received communications respecting these proposed schemes of the soldiers in confession, and to urge him to make judicial examinations into the affair and to punish the offenders; yet even this made little impression on Hinojosa. Notwithstanding these and other intimations of the plot, Hinojosa obstinately refused to attend to the suggestions of Hondegardo and others, proudly declaring he had only to hold up his hand to make the soldiers tremble before him. Impatient of any longer delay, the conspirators came at length to the determination of putting the governor Hinojosa to death, and rising in a general insurrection. The principal ringleaders in this conspiracy were Don Sebastian de Castilla, Egas de Gusman, Basco Godinez, Balthazar Velasquez, and Gomez Hernandez, besides several other soldiers of note, most of whom were then resident in the city of La Plata. Having arranged their plan of operations, Don Sebastian and seven chosen accomplices went one morning to the residence of the governor, as soon as his gate was opened, to execute their vile purpose. The first person they met on entering the house was Alonzo de Castro, the deputy-governor, who questioned them on the reason of their present tumultuous appearance, as they seemed extremely agitated. They immediately put De Castro to death. Then forcing their way into the apartment of Hinojosa, they were astonished to find him gone: But after some search he was found in a retired corner, and dispatched.
