her in the attempt. England refused to give any answer to the demands of France, and demanded in return what was her case against Spain. To this no answer was given. The part then taken by the Duke was to deprecate hostilities, both publicly as Plenipotentiary of England and privately in the various conversations which he had with the Emperor of Russia, who seems to have been the strongest advocate for making war with Spain. The imprudence of the Spaniards has afforded some colour to the right assumed by their enemies of interfering with their affairs, for they have upon several occasions attempted to foment the troubles which either existed or threatened to appear both in Naples and Piedmont; and the Emperor of Russia told the Duke that he had detected the Spanish Minister at St. Petersburg in an attempt to corrupt his soldiers at the time of the mutiny of the Guards, and that he had consequently sent him out of the country. The Duke replied that if the Emperor of Russia had reasonable grounds of complaint against Spain, he would be fully justified in declaring war against her, and that he would advise him to do so if he could march 150,000 men into Spain; but in suffering three years to elapse without making any complaint he had virtually renounced his right to complain, and that it was unfair to rake up a forgotten grievance against Spain at a time when she was menaced by another Power upon other grounds. The Duke said that the Emperor of Russia once talked to him of the practicability of marching an army into Spain, and seemed to think he might do so. The Duke said that the French Government would never allow it, when he said he could send them by sea. The Duke told him it would take 2,000 ships. One of the arguments of the Emperor of Russia was this: that constituted as their Governments were (military Governments) it was impossible for them to tolerate consistently with their own security any revolution which originated in military insubordination.
