The emperor is warned that the king of England would assuredly break off his alliance with him the moment he had no longer cause to dread the Pretender; and he is reminded that while the former was at best a cold and crafty ally, he would find the prince a staunch and powerful confederate. "It is therefore," he continues, "for Your Majesty's interest to bring about a marriage, and not to allow the royal house of Stuart to become extinct. And even, taking the worst for granted, if the Pretender did not succeed in realizing his pretensions to the British throne, it would be only fair on the part of Your Majesty to remind King George that the marriage would detract nothing from, and have no influence whatever upon, the alliance between him and Your Majesty." Sobiesky closes his letter by assuring the emperor how deeply he regretted his displeasure, and by declaring that he had acted in good faith to the emperor; "for," said he, "I would never have advocated this match without the consent of Your Majesty had I not received the written assurance of Her Majesty the empress Eleonora (the emperor's mother) that she had spoken to Your Majesty on this matter. To me this was sufficient; for, considering the course of European politics, I dared not hope to receive open signs of Your Majesty's approbation." Count Praschma remarks, in his private report to the emperor, that he believes "Prince Sobiesky places great reliance on the assistance proffered by the Roman Curia, on the good-will displayed by the regent of France, no less than on the guarantee ensured to him by Sweden and Prussia, and on the concurrence of Russia."
