Soto Expedition to Florida, the American South and Texas, 1539-1543

The King of Spain gave Hernando de Soto the funds and resources to conquer and colonize the American continent. Not knowing the size of North America, the King gave Soto four years to conquer America and locate riches that would entice Spanish settlers and investors to follow. Six-hundred-forty volunteers joined the expedition that left Cuba in 1539. Among them were expert tradesmen that might help settle a new land. Carpenters, merchants, engineers, blacksmiths, priests, and farmers were among Soto’s “army.” They carried with them all manner of military equipment, as well as seeds, nails, horses, dogs, and pigs. The massive entourage spent four years walking four-thousand miles through the interior of North America but did not establish a settlement. The Soto expedition began in Cuba and moved on to cover territory in what today are the states of Florida, Georgia, North and South Carolina, Tennessee, Alabama, Mississippi, Arkansas, Oklahoma, Louisiana, and Texas. For its exact route during the four-year journey, see the reference map accessible from this document’s home page.

From his campaigns against the Inca in Peru, Soto had earned a reputation for killing Indians as sport, and his North American expedition was among the most savage on record. Soto’s army brutalized and enslaved Indians they encountered all across the southeast, killing thousands and spreading disease throughout the native populations. Many nations first observed on this trip were decimated by diseases introduced during their first contact with Europeans.

Overcome with fever in the third year of the trip, Soto died in May 1542 on the banks of the Mississippi River. Before dying, he conferred command of the expedition to Luys de Moscoso. Moscoso hid Soto’s death from the local Indians because Soto had told them that he was immortal, but when Indian servants became curious about a fresh grave, Moscoso had unearthed the explorer’s body, wrapped it in cloth, weighted it with sand, and sunk it in the river.

Once in control of the expedition, Moscoso tried to discover the fastest route home. Indian guides, however, led the Spanish into the wastes of east Texas in the hope that they would be lost and then starve. Moscoso managed to find his way back to the Mississippi where the expedition built seven small ships in six months. The remaining Spaniards and their animals then set sail downriver. As they progressed, groups of Indians in large canoes attacked them. When the Spanish sent boats with soldiers to repulse these attacks, the Indians ditched the Spaniards’ boats, beat them with wooden clubs, and then drowned the armor-clad soldiers. The Indians then followed a bowshot behind the ships and patiently shot the Spaniards with arrows. Up to fifty canoes followed the Spaniards, attacking them day and night. The Spanish finally reached the mouth of the Mississippi River and headed west. They sailed into the Rio Panico, Mexico, on September 10, 1543, with only 300 men remaining from the original 640.

Document Note

This report was written by the factor, an official of the Spanish court, specifically for the King. Biedma wrote it while living in Mexico and presented it to the King in 1544. It was first published in 1841 in a French translation. The original text was published by Buckingham Smith in his Colleccion de Varios Documentos para la historia de la Florida y tierras Adyacentes. Tomo I (London, 1857).
