This peril was only an incentive to the adventurous spirit of the Spanish commander. To abandon the enterprise and return without the gold, would be not only humiliating, but would be his utter ruin. He had already expended in the undertaking all that he possessed. He had no scruples of conscience to retard his march, however sanguinary the hostility of the natives might render it. It was the doctrine of the so-called church at Rome, that Christians were entitled to the possessions of the heathen; and though De Soto himself by no means professed to be actuated by that motive, the principle unquestionably influenced nearly his whole army.
But he did assume that he was a peaceful traveller, desiring to cultivate only friendly relations with the natives, and that he had a right to explore this wilderness of the new world in search of those precious medals of which the natives knew not the value, but which were of so much importance to the interest of all civilized nations.
For three days the Spaniards toiled painfully along over an arid, desert plain, beneath a burning sun. About noon on the fourth day they reached a vast swamp, probably near the Estauhatchee river. This swamp was bordered by a gloomy forest, with gigantic trees, and a dense, impervious underbrush, ever stimulated to wonderful luxuriance by an almost tropical sun and a moist and spongy soil. Through this morass the Indians, during generations long since passed away, had constructed a narrow trail or path about three feet wide. This passage, on both sides, was walled up by thorny and entangled vegetation almost as impenetrable as if it were brick or stone.
In the centre of this gloomy forest, there was a sheet of shallow water about a mile and a half in width and extending north and south as far as the eye could reach. The Indians had discovered a ford across this lake till they came to the main channel in the centre, which was about one hundred and twenty feet wide. This channel, in the motionless waters, was passed by a rude bridge consisting of trees tied together.
De Soto encamped on the borders of this gloomy region for a short time to become acquainted with the route and to force the passage. There were various spots where the Indians, familiar with the whole region, lay in ambush. From their unseen coverts, they could assail the Spaniards with a shower of arrows as they defiled through the narrow pass, and escape beyond any possibility of pursuit. Compelling some Indians to operate as guides, under penalty of being torn to pieces by bloodhounds, De Soto commenced his march just after midnight. Two hundred picked men on foot, but carefully encased in armor, led the advance in a long line two abreast. Every man was furnished with his day's allowance of food in the form of roasted kernels of corn. They pressed along through a path which they could not lose, and from which they could not wander, till they reached the lake. Here the guides led them along by a narrow ford, up to their waists in water, till they reached the bridge of logs. The advance-guard had just passed over this bridge when the day dawned, and they were discovered by the Indians, who had not supposed they would attempt to cross the morass by night.
The Appalachian warriors, with hideous yells and great bravery, rushed into the lake to meet their foes. Here Spaniard and Floridian grappled in the death struggle up to their waists in water. The steel-clad Spaniards, with their superior arms, prevailed, and the natives repulsed, rushed into the narrow defile upon the other side of the lake. The main body of the army pressed on, though continually and fiercely assailed by the arrows of the Indians. Arriving at a point where there was an expanse of tolerably dry ground, De Soto sent into the forests around forty skirmishers to keep off the Indians, while a hundred and fifty men were employed in felling trees and burning brush, in preparation for an encampment for the night.
Exhausted by the toil of the march and of the battle; drenched with the waters of the lake; many of them suffering from wounds, they threw themselves down upon the hot and smouldering soil for sleep. But there was no repose for them that night. During all the hours of darkness, the prowling natives kept up a continuous clamor, with ever recurring assaults. With the first dawn of the morning the Spaniards resumed their march, anxious to get out of the defile and into the open prairie beyond, where they could avail themselves of their horses, of which the Indians stood in great dread. As they gradually emerged from the impenetrable thicket into the more open forest, the army could be spread out more effectually, and the horsesmen could be brought a little more into action. But here the valor of the natives did not forsake them.
"As soon as the Spaniards," writes Mr. Irving, "entered this more open woodland, they were assailed by showers of arrows on every side. The Indians, scattered about among the thickets, sallied forth, plied their bows with intense rapidity, and plunged again into the forest. The horses were of no avail. The arquebusiers and archers seemed no longer a terror; for in the time a Spaniard could make one discharge, and reload his musket or place another bolt in his cross-bow, an Indian would launch six or seven arrows. Scarce had one arrow taken flight before another was in the bow. For two long leagues did the Spaniards toil and fight their way forward through this forest.
"Irritated and mortified by these galling attacks and the impossibility of retaliating, at length they emerged into an open and level country. Here, overjoyed at being freed from this forest prison, they gave reins to their horses, and free vent to their smothered rage, and scoured the plain, lancing and cutting down every Indian they encountered. But few of the enemy were taken prisoners, many were put to the sword."
