In this conjunction of hostile planets, Ferdinand had recourse to his favourite policy of wile and stratagem. Turning against the Jews the very treaty Almamen had once sought to obtain in their favour, he caused it to be circulated, privately, that the Jews, anxious to purchase their peace with him, had promised to betray the Moorish towns, and Granada itself into his hands. The paper, which Ferdinand himself had signed in his interview with Almamen, and of which, on the capture of the Hebrew, he had taken care to repossess himself, he gave to a spy whom he sent, disguised as a Jew, into one of the revolted cities.
Private intelligence reached the Moorish ringleader of the arrival of this envoy. He was seized, and the document found on his person. The form of the words drawn up by Almamen (who had carefully omitted mention of his own name--whether that which he assumed, or that which, by birth, he should have borne) merely conveyed the compact, that if by a Jew, within two weeks from the date therein specified, Granada was delivered to the Christian king, the Jews should enjoy certain immunities and rights.
The discovery of this document filled the Moors of the city to which the spy had been sent with a fury that no words can describe. Always distrusting their allies, they now imagined they perceived the sole reason of their sudden enthusiasm, of their demand for arms. The mob rose: the principal Jews were seized and massacred without trial; some by the wrath of the multitude, some by the slower tortures of the magistrate. Messengers were sent to the different revolted towns, and, above all, to Granada itself, to put the Moslems on their guard against these unhappy enemies of either party. At once covetous and ferocious, the Moors rivalled the Inquisition in their cruelty, and Ferdinand in their extortion.
It was the dark fate of Almamen, as of most premature and heated liberators of the enslaved, to double the terrors and the evils he had sought to cure. The warning arrived at Granada at a time in which the vizier, Jusef, had received the commands of his royal master, still at the siege of Salobrena, to use every exertion to fill the wasting treasuries. Fearful of new exactions against the Moors, the vizier hailed, as a message from Heaven, so just a pretext for a new and sweeping impost on the Jews. The spendthrift violence of the mob was restrained, because it was headed by the authorities, who were wisely anxious that the state should have no rival in the plunder it required; and the work of confiscation and robbery was carried on with a majestic and calm regularity, which redounded no less to the credit of Jusef than it contributed to the coffers of the king.
