Under the arrangement to be proposed to the Ottoman Porte, Greece was to be granted complete autonomy, under the suzerainty of the Sultan, and was to pay a fixed annual tribute. It was to be governed by authorities whom its people were to nominate. In order to bring about a complete separation between the individuals of the two nations and to prevent the collisions resulting from a long struggle, the Greeks were to enter upon possession of all Turkish property, either on the continent or in the isles of Greece, on condition of indemnifying the former proprietors by the payment of an annual sum to be added to the tribute. By an additional secret article it was provided that “if, within one month, the Ottoman Porte did not agree to accept the mediation of the three Powers and consent to an armistice, the signatories of the treaty would find the necessity for an approximation with the Greeks by entering into relations with them, and would employ all their means for the accomplishment of the objects of the treaty without, however, taking any part in the hostilities between the two contending parties.” In accordance with this treaty, a demand was made on the Porte, by the ambassadors of the three Powers, for an armistice, and for a pacification of Greece on the basis above described. The Porte indignantly refused to entertain the proposed mediation. It denied the right of the Powers to intervene as regards its Greek subjects. In a manifesto to its own people, the Porte justified its refusal to mediate on the proposed basis. It denied that the Greeks had any cause for complaint against the Ottoman rule. “It is notorious,” it said, “that these Greeks have been treated like Mussulmans in every respect and as to everything which regards their property, their personal security, and the defence of their homes, and that they have been loaded with benefits by the present Sultan.” The negotiations between the Porte and the ambassadors were protracted by the former, in order that an Egyptian fleet, bringing large reinforcements to Ibrahim in Greece, might arrive at Navarino before the conclusion of them. After the final rejection of the proposals of the ambassadors, instructions were given to the combined fleet of the three Powers to effect a blockade of the Greek ports, and to prevent the entrance or departure of any Turkish or Egyptian vessels of war.
