text_A: Gladstone, who had left the Liberal leadership and retired from public life, was appalled by reports of atrocities in Bulgaria, and in August 1876, penned a hastily written pamphlet arguing that the Turks should be deprived of Bulgaria because of what they had done there. He sent a copy to Disraeli, who called it "vindictive and ill-written ... of all the Bulgarian horrors perhaps the greatest". Gladstone's pamphlet became an immense best-seller and rallied the Liberals to urge that the Ottoman Empire should no longer be a British ally. Disraeli wrote to Lord Salisbury on 3 September, "Had it not been for these unhappy 'atrocities', we should have settled a peace very honourable to England and satisfactory to Europe. Now we are obliged to work from a new point of departure, and dictate to Turkey, who has forfeited all sympathy." In spite of this, Disraeli's policy favoured Constantinople and the territorial integrity of its empire.
text_B: If Gladstone's recommendation is followed, is a Bulgarian considered under Ottoman rule after August, 1876?
NO.
