The conspirators, after having deliberated on several different plans, for ensuring the success of their enterprise, at last adopted one proposed by the archbishop, who had consulted the principal Spanish minister on the occasion. It was, therefore, unanimously agreed, that on the fifth of August, the Jews should not only set fire to the four corners of the palace, but to several other houses in the city, by which means the people would be sufficiently employed in their different quarters, without attending to what passed in the palace, whither the conspirators were to repair immediately, on pretence of endeavouring to extinguish the flames; but, in the midst of the hurry and confusion occasioned by so dreadful an event, they were to seek an opportunity of approaching the king, and stabbing him to the heart, whilst the duke de Caminha should secure the person of the queen, together with those of the young princes, her sons, in order to take the same advantage of their situation, which had been taken of the princess of Mantua, to enforce the surrender of the citadel. Fire-works were at the same time to be employed in burning the fleet; and the archbishop, together with the grand inquisitor, and the officers of the holy brotherhood, were to parade through the streets, to prevent any commotions amongst the people; who would never venture to take an active part in the business, from their natural dread of drawing upon themselves the indignation of the inquisition. The marquis de Villa-Real was to be appointed governor of the kingdom, till the Spanish monarch should make known his intentions relative to the measures to be taken on so important an occasion. There was, however, no certainty of the people declaring in their favour: it was, therefore, deemed necessary to be provided with troops to enforce their obedience. They, accordingly, decided on applying to the count-duke to engage him to send a considerable fleet on the coast; which would then be in readiness to enter the port on the first breaking out of the conspiracy; and immediately on receiving intelligence of their success, he was to be requested to march troops to the frontiers, to subdue all, and every one, who should be tempted to make any further resistance. This plan, however, was easier imagined than executed, it being extremely difficult for the conspirators to hold any secret correspondance with the prime minister; the king having placed guards on the frontiers, in consequence of the discovery he had made of the princess of Mantua's having written to Madrid, with the strictest orders not to allow any one to quit the kingdom, without his express permission. Any attempt to corrupt these guards might be attended with danger, since those who betrayed their sovereign, might likewise betray them, and deliver up their letters, relating, at the same time, the methods employed to tempt them from their duty.
