Unfortunately, the Marquis de Villeneuve, Louis XV’s ambassador, and the Comte de Bonneval, who had been converted to Islam, had been the last Frenchmen who had supported the Sublime Porte against the Russian Tsar’s hostility and endeavoured to use Islam as the protector of the liberty of peoples imperilled by the Tsars; and yet this old policy of France had the advantage both of benefiting French trade and counterbalancing the power of the enemies of France.[46] On the other hand, at the Congress of Sistovo in 1791, Sir Robert Murray Keith, who acted as mediator in the conclusion of the Austro-Turkish treaty of peace, recommended his fellow-countrymen “to let the Turks dwindle down in their own dull way.” So now French policy and English policy were going the same way. During the reign of Charles X, the Polignac Cabinet was willing to sacrifice Constantinople to the Russians in return for the left bank of the Rhine, and in 1828 Chateaubriand, French ambassador at Rome, favoured an alliance with the Tsar in order to obtain the revision of the 1815 treaties, at the cost of Constantinople. Moreover, Admiral Sir Edward Codrington, by destroying the Turco-Egyptian fleet at Navarino on October 20, 1827, with the combined fleets of Great Britain, France, and Russia, furthered the Russian Tsar’s plans. As the direct capture of the Straits was bound to raise diplomatic difficulties, Nicholas I, on September 4, 1892, summoned a secret council to discuss what policy Russia was to pursue on this point. The opinion which prevailed was expressed in a memorandum drawn up by a former diplomatist, Dimitri Dashkov, then Minister of Justice, and in a draft partition of the Turkish Empire penned by a Greek, Capodistria. This secret committee, dreading the opposition of the Western States, decided to postpone the partition lest, as Great Britain and France refused their consent, it should not finally benefit the designs of Russia and Greece on Constantinople. These secret debates have been summed up in a book published in 1877;[47] and M. Goriainov, in the book he wrote on this question in 1910,[48] thought it proper to praise the consistent magnanimity of the Tsars towards the Turks—whereas the policy which maintained that no reforms would ever be instituted by Turkey of her own free-will if they were not urged on by diplomatic intrigues or international interference, and that “the sick man” could only be restored to health by the intervention of Christendom and under the Orthodox tutelage, was the real cause of the decay of Turkey and the origin of all the intricacies of the Eastern problem.
