The Jacobites were in ecstasies at this new phase of their old enterprise. By Charles's adhesion, their scheme was stripped of all those prejudices which had insured its ruin with the English. It had no longer the unpopular aspect of a French invasion; it was no longer headed by a Popish but a Protestant leader; it was no longer consigned to an untried or doubtful general, but to one of the most victorious monarchs living, who came as a Protestant to call on a Protestant nation to receive their rightful king. Money was not wanting. Spain remitted to Baron Spaar a million of livres for the expedition, and the Court of the Pretender offered sixty thousand pounds. But unfortunately for the Pretender, at the moment that the Swedish hero should prepare his armament for the earliest spring, the conspiracy exploded. Whilst the leaders of it had been flattering themselves that it was conducted with the profoundest secrecy, the English Ministry were in possession of its clue. As early as October they had found reason to induce them to intercept the correspondence of Gyllenborg, and had come at once on the letters of Gortz. The matter was kept close, and as nothing was apprehended in winter, Ministers used the time to improve their knowledge of the scheme from the inspected letters passing between Gortz and Gyllenborg. On the king's return it was resolved to act, and accordingly Stanhope laid the information regarding this formidable conspiracy before the Council, and proposed that the Swedish Minister, who had clearly, by conspiring against the Government to which he was accredited, violated the law of nations, and deprived himself of its protection, should be arrested. The Cabinet at once assented to the proposal, and General Wade, a man of firm and resolute military habits, was ordered to make the arrest of the Ambassador. The general found Count Gyllenborg busy making up his despatches, which, after announcing laconically his errand, Wade took possession of, and then demanded the contents of his escritoire. The Dutch Government acted in the same manner to Gortz, and the evidence thus obtained was most conclusive. [Illustration: JAMES EDWARD STUART, THE "OLD PRETENDER."]
