The discernment of the King led him to at once reject this insidious proposal, and Ibn-Ammar retired to his tent. The spirit of the minister was not discouraged by his apparent failure; he quietly secured the co-operation of some of the most influential nobles of the court by the bestowal of treasure with which he was amply provided with a view to just such an emergency. The plausible presentations of these powerful allies soon overcame the fears of the monarch, and an insignificant plaything was deposited as the prize of the winner against the magnificent stake of an empire. The tact of the Moslem procured the appointment as judges of those nobles already purchased with his gold. The game proceeded; Alfonso proved no match for his practised opponent, who, when the time arrived to announce his request, demanded the unconditional evacuation of Andalusia by the Christian army. The mortification of the King at this unexpected demand may be imagined, and, in a moment of anger, he even meditated the violation of his royal word; but the efforts of the courtiers, and the tender of a double tribute willingly contributed by the government of Seville, appeased his vexation, and he relinquished with reluctance the splendid prize already within his grasp. Thus, by the shrewdness and cunning of a statesman, whose act has no parallel in the annals of diplomacy, the matured plans of an able sovereign were foiled; a national calamity was averted; and means were even provided for the further aggrandizement of a territory whose effeminate government and demoralized condition had invited the attack of a formidable invader. Not only Seville, but not improbably the other states of Andalusia and of Eastern Spain as well, were saved by the ruse of Ibn-Ammar, and the end of the death-struggle between Christian and Moslem in the Peninsula was protracted for more than four hundred years. The military genius of Alfonso, the distinction and experience he had gained in a long series of victorious campaigns, the tested valor of a numerous army excited by the spirit of military emulation, and the blind fury of religious zeal constantly inflamed by fanatics, justify the presumption that the fall of Seville would have soon been followed by the subjection of every other Moslem state, and that, upon apparently so insignificant a thing as a game of chess, once depended the existence and the destinies of the Hispano-Arab domination. The obligation due to the ingenuity and perseverance of Ibn-Ammar may be appreciated when it is recalled that a hundred and sixty-three years elapsed after the retirement of Alfonso from the walls of Seville before that city passed into the hands of the Christians, and that it was more than three centuries after that event when, by the surrender of Granada, the Moorish dominion in the Peninsula was finally terminated.
