After the three Spaniards returned to Mexico they united in a report to the Audiencia of Española (Santo Domingo), which is printed in Oviedo's _Historia General y Natural de las Indias_ (tomo III., lib. XXXV., ed. 1853). In April, 1537, they embarked for Spain, but the ship in which Dorantes set sail proved to be unseaworthy and returned to Vera Cruz. Invited to the capital by the Viceroy Mendoza, Dorantes was tendered a commission to explore the northern country, but this project was never carried out. Cabeza de Vaca, in reward for his services, was appointed governor, captain-general, and adelantado of the provinces of Rio de la Plata. Sailing from Cadiz in November, 1540, he reached Brazil in March of the following year. Here he remained seven months, when he sent his vessels ahead to Buenos Ayres and started overland to Asuncion, which he reached in March, 1542, after a remarkable experience in the tropical forests. But the province seems to have needed a man of sterner stuff than Alvar Nuñez, for he soon became the subject of animosity and intrigue, which finally resulted in open rebellion, and his arrest in April, 1543. He was kept under close guard for about two years, when he was sent to Spain, and in 1551 was sentenced to banishment in Africa for eight years--a judgment that does not seem to have been carried out, for after serving probably a year or so in mild captivity at Seville, he was acquitted. He died in 1557. Of the subsequent career of Castillo little is known. He returned to New Spain, became a citizen of the City of Mexico, married a widow, and was granted half the rents of the Indian town of Tehuacan. Dorantes, as has been stated, for some reason did not carry out the plan of exploring the north, perhaps because of the projected expedition of Coronado, the way for which was led by Fray Marcos de Niza in 1539 with the negro Estévan as a guide. Dorantes served Mendoza in the conquest of Jalisco, and married Doña María de la Torre, a widow, by whom he had a large family. One of his sons, Balthasar, sometime king's treasurer of Vera Cruz, was born about the middle of the century, and on the death of his father inherited an _encomienda_ that produced an income of five thousand pesos a year. Another son, Gaspar, inherited the _encomienda_ of the pueblos of Ocava; and another, Melchior, "an _encomienda_ of Indians and of very good rents." Of Estévan there is somewhat more definite information. Well on the road toward the north in 1539, he was sent ahead by Fray Marcos to report the character of the country and its people, and with rattle in hand and accompanied by many Indians of the present Gila River region, entered Háwikuh, the first of the Seven Cities of Cibola. Here Estévan and most of his Indian followers were put to death by the Zuñis; those who escaped fled to Fray Marcos, whose life was threatened but who saved himself by regaling the natives with the contents of his pack.
