His privy council was immediately summoned and the resolutions taken therein were, in a few days afterwards, put into execution. Eleven o'clock in the night of the fifth of August being, according to the intercepted letters, appointed by the conspirators to commence their operations, his majesty, under pretence of a general review in the great court of the palace, called in all the troops quartered in the neighbourhood, at ten o'clock that same morning. He also gave with his own hands, and in secret, several sealed notes to those of his courtiers whom he knew to be the most attached to his person, with strict orders not to open their respective billets till twelve at noon, when the commands contained therein must be punctually and immediately obeyed. About the same hour, the king, pretending business, sent for the archbishop and the marquis de Villa-Real into his cabinet, where their persons were instantly seized; whilst the captain of the guard arrested the duke de Caminha in the public market-place at the same moment. The sealed billets being then opened, the persons to whom they were addressed, in obedience to their contents, separately seized on a conspirator, and conveyed him to prison, there to be strictly guarded till farther orders; and such was the prudence of the measures taken on this occasion, and so faithfully were they executed, that, in less than an hour the forty-seven conspirators were secured, without even the smallest effort being made towards effecting their escape. The people, on the first report of the conspiracy, crowded tumultuously to the palace, and loudly demanded that the traitors should be instantly delivered up to them. But, though the king was delighted with the affection displayed by his subjects, he felt uneasy at such a multitude, being thus suddenly assembled; fearing such commotions might become habitual, and end, as is always the case, in sedition. He, therefore, after expressing his acknowledgments for their solicitude for the welfare of his person, and assuring them the traitors should meet with the punishment due to their crimes, gave orders to the magistrates to disperse them. This prince, however, lest the resentment of the people should abate, and, as it frequently happens, their furious rage towards the criminals turn to sentiments of commiseration, on reflecting on their wretchedness, thought proper to make public that the design of the conspirators was not only to assassinate him, with the whole of the royal family, but to set fire to the city, when every thing which escaped the fury of the flames must naturally become the prey of the rebels: that Spain, to prevent any future conspiracies, and to wreak its vengeance on the Portugueze, had resolved on peopling the town with a colony of Castilians, and to transport all the citizens to the mines in America, where they would be buried alive in those dreadful abysses, in which they had already destroyed so many miserable human beings.
