Though deeply imbued with these sentiments, the Elector of Brandenburg had hitherto been deterred from lending them any assistance, lest, should they be forced to make a peace with the King of France, the whole power and vengeance of that monarch might be directed against himself. He now induced the Emperor Leopold to enter into an alliance with him, by virtue of which he levied a force of twenty-four thousand men, to be joined with an equal number furnished by himself, for the purpose of opposing the advances of Louis. Though the secret treaty which the Emperor had made with France, binding himself not to afford aid to any member of the Triple Alliance, and of which the Elector was in ignorance, limited the employment of the imperial army strictly to the protection of the empire, and consequently prevented it from marching at once to the support of the provinces, its movement was of considerable advantage to their affairs, in calling off Turenne from Bois-le-Duc, to which he had laid siege, to the defence of the places on the Rhine. The Bishops of Muenster and Cologne, also, whom the brave defence of the garrison of Groningen had forced to raise the siege, were under the necessity of abandoning both that province and Guelderland, and hastening to the protection of their own territories. Among the benefits which the Dutch anticipated with the utmost confidence as the consequence of the elevation of the Prince of Orange to his paternal dignities was the appeasing the hostility of his uncle, the King of England. In this, however, they were wholly deceived. On the meeting of Parliament in this year, the chancellor, Shaftesbury, addressed the two Houses in a strain of hostile feeling to the Dutch nation, more bitter than the court as yet ventured to express. He represented that, "besides the personal indignities in the way of pictures, medals, and other public affronts which the King received from the States, they came at last to such a height of insolence as to deny him the honor of the flag, though an undoubted jewel of the crown, and disputed the King's title to it in all the courts of Europe, making great offers to the French King if he would stand by them in this particular.
