The chief was to assemble his warriors, to the number of about ten thousand, upon an extensive plain, just outside the city, ostensibly to gratify De Soto with the splendors of a peaceable parade. To disarm all suspicion, they were to appear without any weapons of war, which weapons were however previously to be concealed in the long grass of the prairie. De Soto was to be invited to walk out with the chief to witness the spectacle. Twelve very powerful Indians, with concealed arms, were to accompany the chief or to be near at hand. It was supposed that the pageant would call out nearly all the Spaniards, and that they would be carelessly sauntering over the plain. At a given signal, the twelve Indians were to rush upon De Soto, and take him captive if possible, or if it were inevitable, put him to death. At the same moment the whole band of native warriors, grasping their arms, was to rush upon the Spaniards in overpowering numbers of ten to one. In this way it was supposed that every man could speedily be put to death or captured. Those who were taken prisoners were to be exposed to the utmost ingenuity of Indian torture. This seemed a very plausible story. De Soto, upon careful inquiry, became satisfied of its truth. He consulted his captains, and decided to be so prepared for the emergence, that should he be thus attacked, the Indian chief would fall into the trap which he had prepared for his victims. The designated day arrived. The sun rose in a cloudless sky and a gentle breeze swept the prairie. Early in the morning, Vitachuco called upon De Soto, and very obsequiously solicited him to confer upon him the honor of witnessing a grand muster of his subjects. He said they would appear entirely unarmed, but he wished De Soto to witness their evolutions, that he might compare them with the military drill of European armies. De Soto, assuming a very friendly and unsuspicious air, assured the chief, that he should be very happy to witness the pageant. And to add to its imposing display, and in his turn to do something to interest the natives, he said he would call out his whole force of infantry and cavalry, and arrange them in full battle array on the opposite side of the plain. The chief was evidently much embarrassed by this proposition, but he did not venture to present any obstacles. Knowing the valor and ferocity of his troops, he still thought that with De Soto as his captive, he could crush the Spaniards by overwhelming numbers. Matters being thus arranged, the whole Spanish army, in its most glittering array, defiled upon the plain. De Soto was secretly well armed. Servants were ready with two of the finest horses to rush to his aid. A body-guard of twelve of his most stalwart men loitered carelessly around him.
