Bernal Díaz del Castillo was a Spanish conquistador, who participated as a foot soldier in the conquest of Mexico with Hernán Cortés. In his later years he was an encomendero and governor in Chiapas and Guatemala where he wrote his memoirs called "The True History of the Conquest of New Spain". He began his account of the conquest almost thirty years after the events and later revised and expanded it in response to the account published by Cortes's chaplain Francisco López de Gómara, which he considered to be largely inaccurate in that it did not give due recognition to the efforts and sacrifices of common soldiers.
