In the disordered condition of the country years passed before an expedition to the golden land of the Omaguas could be contemplated. The Marquis of Cañete readily perceived how favorable an occasion this story of the Brazilian visitors and the “dorado fever” it excited afforded him. After a personal interview with the Indians he proceeded energetically with preparations for an expedition to the shores of the Middle Amazon. Drafts were made upon the royal treasury for this object. The disorderly elements in the country seized the occasion with not less eagerness than the viceroy to secure for themselves an unmolested withdrawal; and thus the dorado, which had provoked the conquest of New Granada and had brought the colony of Venezuela to the verge of destruction, was this time the beneficent messenger of rest to Peru.

A campaign of this kind required a strong leader. The choice of the Marquis of Cañete fell upon Pedro de Ursua, who readily accepted the dangerous commission. Besides several other rewards he was to receive, in case of success, the title and all the rights of a governor of the countries expected to be conquered and settled.

A whole year passed before the preparations were completed, and it was not till the spring of 1560 that Ursua collected his men at Santa Cruz de Capacoba, on the Rio Llamas, a branch of the Huallaga, where he had had boats built for the voyage to the Amazon and upon it. It was really a “picked company” that met there. The scum of Peru formed the principal part of it; the majority, men accustomed to everything except order and morals; and with them were women.

To lead such a rabble with success in the face of uncertainties required an earnest and prudent, and at the same time a decided, character of moral worth. Ursua was frivolous and indolent, and often rashly bold. His preparations were incomplete. Much was still lacking when his money had all been spent, and his men were eager to embark. With the help of some officers—“all doughty champions with elastic consciences,” says Simon—Ursua forced the priest of Santa Cruz to “lend” him all his ready money, some four or five thousand pesos. By this act he set the example of violence.

He likewise furnished an example of immorality from the beginning. He kept up a close relation with Iñez de Atienza of Pinira (near the coast), the young and beautiful widow of Pedro de Arcos. Without heeding the counsels of his friends, he took his mistress with him on this campaign in search of the dorado, and lived with her so intimately that the chronicler feels impelled to make the remark, in excuse, that “they all said, indeed, that he intended at some later time to marry Iñez de Atienza.”

While the start was delayed, in consequence of the defects in Ursua’s preparations, trouble was brewing in the camp. It culminated in crime—the murder of Ursua’s lieutenant, Pedro Ramiro. Ursua’s behavior in this affair (he drew the perpetrators of the murder from their hiding-places by promising them immunity and then in the face of his pledge had them arrested and hung) made him personal enemies. With the other elements of discontent among the men were now associated hatred and vindictiveness against their leader.

On the first day of July, 1560, Juan de Vargas was able to go forward with an advance guard in a brigantine to the mouth of the Rio Ucayali. The main body, increased by the colonists of Moyobamba with their goods, should have followed at once, but of all the fleet only three flatboats and one brigantine were seaworthy; the other vessels were unavailable. It was necessary to build rafts and canoes. The embarkation could not be effected till September 26th, when it took place in great confusion. The available space in the boats was unevenly allotted; only forty out of three hundred horses were taken; and all the cattle were left, without masters, on the shore. The flotilla at last moved slowly down along the thickly wooded shores of the Rio Huallaga. It sailed three hundred leagues, according to Pedro Simon (vi.), without passing in sight of a single Indian hut. Harmony among the men was not promoted by their getting under way. Every one appeared dissatisfied and envious of the others, while most of them censured Pedro de Ursua. At the mouth of the Ucayali they came upon the advance expedition under Juan de Vargas; the men were nearly famished in the midst of the richest vegetation. Their vessel had rotted, and it was necessary to distribute them among those who crowded the other already overloaded boats. Fresh discontent arose over this measure, and the dissatisfaction was increased by the fact that Ursua always claimed a full share of room for himself and Iñez de Atienza. At last settlements were reached above the mouth of the Rio Napo, in which were found maize, sweet potatoes, beans, and other vegetables. At one of these places the flotilla landed, and the boats were repaired and rebuilt. Some of the Brazilian Indians who had given the original motive to the expedition and who accompanied it as guides pointed farther eastward as the direction of the rich country of which they were in search. The Ticunas, indeed, on the southern side of the Amazon (between the Ucayali and the Yavari) possessed some gold, but the dorado lived north of that river. The fleet therefore sailed on, despite the murmurs of the men, who had become tired of the constant promises and deceptions.

Before Christmas of 1560 Ursua reached Machiparo, where he was near the country of the Omaguas. Encouraged by the extent of the Indian settlements he found there, and by the friendly demeanor of the inhabitants, he determined to make a longer sojourn at that place, for his crews were worn out by their labor, especially by rowing. The men were glad to resign themselves to rest on the shore, but their idleness also gave them leisure to consider and mature criminal plans. Besides their dissatisfaction with Ursua’s leading, personal hatred, and many worse passions, thoughts of wider bearing lay at the bottom of their schemes.

Some of the members of the band had divined the secret thoughts of the viceroy of Peru, or had joined the expedition while realizing the improbability of the dorado legend, in order to use it for their own purposes. It is only certain that a conspiracy against Ursua was formed at Machiparo. He and his lieutenant were to be killed, and Fernando de Guzman, a young knight from Seville and the ensign of the campaign, was to be chosen commander in Ursua’s place. Under his direction they would return to Peru and with armed hand conquer the country, expel the royal officers, and establish a new kingdom there. The soul of this conspiracy was the Biscayan Lope de Aguirre.

Born at Oñate in Biscay, Aguirre was then about fifty years old. He had spent twenty years in Peru, chiefly in the occupation of a horse-trainer. Involved in all kinds of violent and seditious acts, he had been several times condemned to death and then pardoned, and having become at last a fugitive from province to province, was glad of the opportunity to join Ursua’s expedition. He is described as having been “small and spare in figure, ugly, ... with black beard and an eagle eye, which he turned straight upon others, particularly when he was angry.” Burning through and through with hatred against the Spanish Government, at home, at the same time, in all circles and ranks, endowed with remarkable shrewdness and great physical and mental force—a logical and impressive speaker, withal—with clearly defined purposes, he was in every respect a dangerous man. He was the most detestable character of the conquest.
