The new Foreign Minister speedily availed himself of this offer; and the cause of peace was greatly furthered by secret negotiations which he carried on with Count Shuvaloff. The Russian ambassador in London had throughout bent his great abilities to a pacific solution of the dispute, and, on finding out the real nature of the British objections to the San Stefano Treaty, he proceeded to St. Petersburg to persuade the Emperor to accept certain changes. In this he succeeded, and on his return to London was able to come to an agreement with Lord Salisbury (May 30), the chief terms of which clearly foreshadowed those finally adopted at Berlin. In effect they were as follows: The Beaconsfield Cabinet strongly objected to the proposed wide extension of Bulgaria at the expense of other nationalities, and suggested that the districts south of the Balkans, which were peopled almost wholly by Bulgarians, should not be wholly withdrawn from Turkish control, but "should receive a large measure of administrative self-government . . . with a Christian governor." To these proposals the Russian Government gave a conditional assent. Lord Salisbury further claimed that the Sultan should have the right "to canton troops on the frontiers of southern Bulgaria"; and that the militia of that province should be commanded by officers appointed by the Sultan with the consent of Europe. England also undertook to see that the cause of the Greeks in Thessaly and Epirus received the attention of all the Powers, in place of the intervention of Russia alone on their behalf, as specified in the San Stefano Treaty. Respecting the cession of Roumanian Bessarabia to Russia, on which the Emperor Alexander had throughout insisted (see page 205), England expressed "profound regret" at that demand, but undertook not to dispute it at the Congress. On his side the Emperor Alexander consented to restore Bayazid in Asia Minor to the Turks, but insisted on the retention of Batoum, Kars, and Ardahan. Great Britain acceded to this, but hinted that the defence of Turkey in Asia would thenceforth rest especially upon her--a hint to prepare Russia for the Cyprus Convention.
