Then Guzman was murdered, and also the infamous Ynez de Atienza, a woman who bore a shameful part in the affair; and the misshapen Aguirre became leader and "tyrant." His treason was now undisguised, and he commanded the expedition thenceforth not as a Spanish officer, but as a rebel and a pirate. As he steered toward the Atlantic, it was with plans of appalling magnitude and daring. He intended to sail to the Gulf of Mexico, land on the Isthmus, seize Panama, and thence sail to Peru, where he would kill off all who opposed him, and establish an empire of his own! But a curious accident brought his plans to nought. Instead of reaching the mouth of the Amazon, the flotilla drifted to the left, in that wonderfully tangled river, and got into the Rio Negro. The sluggish currents prevented their discovering their mistake, and they worked ahead into the Cassiquiare, and thence into the Orinoco. On the 1st of July, 1561 (a year to a day had been passed in navigating the labyrinth, and the days had been marked with murder right and left), the desperadoes reached the Atlantic Ocean; but through the mouth of the Orinoco, and not, as they had expected, through the Amazon. Seventeen days later they sighted the island of Margarita, where there was a Spanish post. By treachery they seized the island, and then proclaimed their independence of Spain. This step gave Aguirre money and some ammunition, but he still lacked vessels for a voyage by sea. He tried to seize a large vessel which was conveying the provincial Monticinos, a Dominican missionary, to Venezuela; but his treachery was frustrated, and the alarm was given on the mainland. Infuriated by his failure, the little monster butchered the royal officers of Margarita. His plan to reach Panama was balked; but he succeeded at last in capturing a smaller vessel, by means of which he landed on the coast of Venezuela in August, 1561. His career on the mainland was one of crime and rapine. The people, taken by surprise, and unable to make immediate resistance to the outlaw, fled at his approach. The authorities sent as far as New Granada in their appeals for help; and all northern South America was terrorized. Aguirre proceeded without opposition as far as Barquecimeto. He found that place deserted; but very soon there arrived the maestro de campo, (Colonel) Diego de Paredes, with a hastily collected loyal force. At the same time Quesada, the conqueror of New Granada, was hastening against the traitor with what force he could muster. Aguirre found himself blockaded in Barquecimeto, and his followers began to desert. Finally, left almost alone, Aguirre slew his daughter (who had shared all those awful wanderings) and surrendered himself. The Spanish commander did not wish to execute the arch-traitor; but Aguirre's own followers insisted upon his death, and secured it. * * * * *
