While these events were in progress, Cortez, at the head of an expedition fitted out by Velasquez, the governor of Cuba, was destroying the empire of Montezuma, in Mexico, then recently discovered. The success of Cortez excited the jealousy of Velasquez, for he feared a renunciation of his authority by that bold leader. He sent Pamphilo de Narvaez, with a strong force, to arrest and supersede Cortez; but he was defeated, and most of his troops joined his enemy. Narvaez afterward obtained from the Spanish court a commission as _adelantado_ or Governor of Florida, a territory quite indefinite in extent, reaching from the southern capes of the peninsula to the Panuco River in Mexico. With a force of three April 22, 1528 hundred men, eighty of whom were well mounted, Narvaez landed in Florida, where he raised the royal standard, and took possession of the country for the crown of Spain. With the hope of finding some wealthy region like Mexico and Peru, he penetrated the vast swamps and everglades in the interior of the flat country along the northern shore of the Gulf of Mexico. His men suffered terribly from the almost daily attacks of the natives and the nightly assaults of the deadly malaria of the fens. They reached the fertile regions of the Appalachians; but the capital of the tribe, instead of being a gorgeous city like Mexico or Cuzco, was a mean village of two hundred huts and wigwams. Disappointed, and one third of his number dead, Narvaez turned southward, reached the Gulf near the present site of St. Mark's, on the Appalachie Bay, constructed five frail barks, and launched upon the waters. Nearly all his men, with himself, perished during a storm. Four of the crew, who were saved, wandered for years through the wild regions of Louisiana and Texas, and finally reached a Spanish settlement in Northern Mexico. These men gave the first intelligence of the fate of the expedition. Two years after the return of these members of the expedition of Narvaez, Fernando de Soto planned an expedition to explore the interior of Florida, as all North America was then called, in search of a populous and wealthy region supposed to exist there. By permission of the Spanish monarch, he undertook the exploration and conquest of Florida 1538. {xxxi}at his own risk and expense. He was commissioned governor-general of that country and of Cuba for life. Leaving his wife to govern Cuba during his absence, he sailed in June, 1539, and landed at Tampa Bay with a force of six hundred men in complete June 25, 1539 armor.
