<P> There are a number of discrepancies in the various accounts of the event . According to Cortés himself, on 27 February 1525, he learned from a citizen of Tenochtitlan, Mexicalcingo, that Cuauhtémoc; Coanacoch, the ruler of Texcoco); and Tetlepanquetzal, the ruler of Tlacopan, were plotting his death . Cortés interrogated them until each confessed and then had Cuauhtémoc; Tetlepanquetzal; and another lord, Tlacatlec, hanged . Cortés wrote that the other lords would be too frightened to plot against him again, as they believed he had uncovered the plan through magic powers . Cortés's account is supported by the historian Francisco López de Gómara . </P> <P> According to Bernal Díaz del Castillo, a conquistador serving under Cortés who recorded his experiences in his book The True History of the Conquest of New Spain, the supposed plot was revealed by two men, named Tapia and Juan Velásquez . Díaz portrays the executions as unjust and based on no evidence, and he admits to having liked Cuauhtémoc personally . He also records Cuauhtémoc giving the following speech to Cortés through his interpreter Malinche: </P> <P> Oh Malinzin (i.e., Cortés)! Now I understand your false promises and the kind of death you have had in store for me . For you are killing me unjustly . May God demand justice from you, as it was taken from me when I entrusted myself to you in my city of Mexico! </P> <P> Díaz wrote that afterwards, Cortés suffered from insomnia because of guilt and badly injured himself while he was wandering at night . </P>
