It was supposed at that time that there must be a strait somewhere north of Panama across the narrow isthmus, which would connect the waters of the Atlantic and Pacific oceans. Several expeditions had been fitted out in search of this all-important passage. Almost invariably a company of priests joined these expeditions, who exerted all their energies to convert the Indians to nominal Christianity. A fanatic adventurer by the name of Giles Gonzales, acquired much celebrity for his success in inducing the natives to accept the Christian faith and to acknowledge fealty to the king of Spain. He was at the head of one hundred steel-clad warriors. His mode of persuasion, though unique, was very potent. When he approached the seat of the chief of Nicaragua, he sent a courier to him with the following message: "I am coming as a friend to teach you the only true religion, and to persuade you to recognize the most powerful monarch on the globe. If you refuse to yield to my teachings, you must prepare for battle, and I challenge you to meet me in the field." The gentle and peace-loving natives contemplated with consternation these fierce Spaniards mounted on powerful war horses, animals which they had never before seen, and glittering in coats of mail. They had no religious creed to which they adhered with any tenacity. The Nicaraguan chief unhesitatingly expressed his readiness to accept the new faith, and in token of friendship, sent Gonzales a quantity of gold, equal it is said in value to seventy-five thousand dollars of our money. The Spanish historian Herrera, whose record is generally deemed in the main accurate, says that the chief, his family, and nine thousand of his subjects, were baptized and became Christians. Influenced by this example, and by the glowing representations of the rewards which were sure to follow the acceptance of the Christian faith, more than thirty-six thousand of the natives were baptized within the space of half a year. The baptismal fees charged by Gonzales amounted to over four hundred thousand dollars. While Gonzales was engaged on his own responsibility in this career of spiritual conquest, with its rich pecuniary accompaniment, Don Pedro sent two of his generals, Ferdinand de Cordova and Ferdinand De Soto, to explore Nicaragua and take possession of it in his name. He assumed that Gonzales, acting without authority, was engaged in a treasonable movement. The two parties soon came into collision.
