In obedience to the Queen, and this her secret counsellor, he was to influence the Marquis de Castellor to extort an act of aggression from the French arms against the German Emperor.
Since the public betrothment of Maria Theresa to the Prince of Lorraine, Isabella had become reconciled to Louis the Fifteenth; and she now wanted to attack the grasping power of the rival Empire, by a concerted act of open hostility. France was to invade Austria on the side of Germany; while Spain, in consequence of the death of the Duke of Parma, should resist the pretensions of the Emperor to that dutchy; and, in support of the rights of Prince Carlos, (the late Duke's kinsman, and Isabella's son,) overrun that part of Italy with Spanish troops.
Her secret counsellor had already moved the cardinal minister of the French King to thwart the establishment of the pragmatic sanction; and through the Queen of Spain and De Paz, he had drawn from the treasury of Philip a large subsidy to support the pretensions of Bavaria.
On the open rupture between Isabella and the Empress, the former was not long at a loss how to revenge herself on the wide ambition of her rival. Her midnight familiar whispered the means. He told her that Gibraltar was not more the fortress of England than of Austria. Whoever possessed that rock, commanded the Mediterranean, and bound all on its banks to his feet. The interest of Austria and the House of Brunswick were now the same. He therefore exhorted her to categorically demand Gibraltar of the King of England; and to make her husband and his council, see the wisdom of considering him the King of England who would restore that gem to the Spanish crown.
One of the last acts of George the First was to reject this demand with a positive refusal; and the following evening saw a tall, dark man, of a noble mien, pass into the private cabinet of the King of Spain. They were alone together for some time; and then the Queen and the two ministers of state being introduced, a paper was signed in their presence by Philip and the stranger, and the royal seals of Spain and of Great Britain solemnly affixed to the deed.
Santa Cruz met this personage as he withdrew through the vestibule of the King's apartment. He knew him, and stood with his hat in his hand till he passed.
