Early in February Muravieff was back at Constantinople. The terms which Halil Pasha had been empowered to offer had not been accepted, but Mehemet Ali had promised Muravieff that, for the present, the Egyptian army should not advance beyond Kiutayeh.[295] Upon the news that no immediate forward movement on the part of Ibrahim was to be apprehended, both the French and British ministers again endeavoured to persuade the Porte to ask that the despatch of the Russian succour might be delayed. According to the Reis-Effendi such a request was actually made to Boutenieff, who replied that he had no ship at his disposal to send to Sevastopol, although a Russian brig of war was at the time at anchor in front of the embassy.[296] On the other hand, accounts of these proceedings, derived from Russian sources, state that the question of postponing the departure of the fleet was never seriously raised.[297] Be that as it may, on February 20, 1833, the Russian squadron, consisting of four sail of the line, three large frigates, a corvette and a brig, entered the Bosphorus and anchored at Buyukdere.
Three days earlier, on February 17, Admiral Roussin, the newly appointed French ambassador to the Sublime Porte, arrived at Constantinople. Upon the appearance of the Russian fleet he at once instructed his dragoman to warn the Porte that, unless the admiral in command were requested to depart within twenty-four hours, he should consider his mission at an end. At the same time he tried to induce the British minister to make a similar representation. Mandeville, however, could only reply that he had no authority “to hold language of so high and energetic a character.” Roussin appears to have seen very soon that he had acted with undue precipitation, and that his own withdrawal would not hasten by an hour the departure of the Russian ships. But his next step was scarcely more judicious. On the 21st, he affixed his signature to a document guaranteeing that Mehemet Ali would make peace with the Sultan, upon the terms proposed by Halil Pasha and which had already been rejected. In return the Sublime Porte was to undertake to refuse “foreign succour” of any kind in the future.[298]
It was hoped to satisfy Mehemet Ali by conferring upon him the government of the districts of Acre, Naplous, Jerusalem and Tripoli. He, however, was resolved to extend his rule over the whole of Syria, and to acquire, in addition, the pashalic of Adana and the seaports of Selefkeh and Alaia. Adana possessed an especial value in his eyes, by reason of its forests from which he proposed to obtain the timber necessary for the building of his ships. He understood the difficulties of the Sultan’s position and he was well informed about the rivalries of the Powers.[299] He perceived clearly that he was never likely again to have so favourable an opportunity for pressing his demands upon the Porte. On March 23, accordingly, Reshid Bey arrived at Constantinople bringing a letter in which Mehemet Ali rejected scornfully Admiral Roussin’s proposals. He would rather, he declared, meet with an honourable death than submit to be deprived of territories which were his by right of conquest. At the same time, Ibrahim was directed to march on Constantinople if, within five days of Reshid’s arrival, the Sultan should not have agreed to the required concessions.[300]
Terrible consternation prevailed in the Seraglio, and great was the perplexity at the French and British embassies. Roussin counselled a complete surrender to Mehemet Ali, and Mandeville had no alternative to propose. It was decided, finally, that a Turkish plenipotentiary should proceed, accompanied by M. de Varennes, to Ibrahim’s headquarters at Kiutayeh with authority to offer the pashalics of Damascus and Aleppo.[301] Ibrahim, however, would not entertain the idea of a compromise, and Varennes could only report the failure of his mission and advise the cession of Adana. In opposition to the recommendations of Mandeville, but with the approbation of Admiral Roussin, the Sultan consented to yield up to his vassal this valuable district.[302] The preliminaries of this agreement, known as the Convention of Kiutayeh were signed on April 8, 1833, and Ibrahim forthwith began his preparations for retiring into Syria.
In the meantime, however, on April 6, a second division of the Russian fleet had arrived in the Bosphorus and 5000 troops had been disembarked on the Asiatic shore opposite to the British embassy at Therapia. The Tsar Nicholas was greatly incensed at Admiral Roussin’s attempts to induce the Porte to ask for the withdrawal of his squadron. Pozzo di Borgo was, in consequence, charged to protest vigorously in Paris against the admiral’s conduct, and the complaints of the Russian ambassador were warmly supported by his colleagues of Austria and Prussia. Broglie, although he might allow Lord Granville to perceive that he was not altogether convinced of the wisdom of Roussin’s actions, invariably met the representations of the agents of the Northern Courts with the reply that the admiral’s conduct was fully approved of by his government.[303] At Constantinople Boutenieff declared emphatically that nothing short of the complete evacuation of Asia Minor by the Egyptians would induce his Imperial master to recall either his fleet or his troops to Sevastopol.[304]
When the list of the pashalics to which Mehemet Ali had been appointed was officially made public, it was seen that no mention had been made of the province of Adana. Upon hearing of this breach of the Convention of Kiutayeh, Ibrahim promptly arrested the homeward march of his army.[305] A few days later, however, on April 22, a third division of the Russian fleet and a second detachment of troops entered the Bosphorus. These reinforcements, which should have added to the Sultan’s powers of resistance, became, in effect, the determining cause of his decision finally to give way about Adana. Ever since the entry of Ibrahim into Asia Minor, the people of Constantinople had been deprived of their usual sources of supply. The necessity of provisioning the Russian fleet and corps d’armée had greatly aggravated the difficulties of the situation. Confronted by the prospect of a famine and a rising of the populace, Mahmud elected to humble his pride and to obtain the withdrawal of the Egyptians at the price of the surrender of Adana.[306] Yet he could not bring himself openly to nominate his rebellious vassal to the governorship of this important province. Ibrahim was, in consequence, officially appointed collector of the crown revenues of the district. Mehemet Ali, provided he could exercise an effective dominion over Adana, was content, in this instance, to waive his claim to be styled its Pasha. In point of fact he was delighted that matters had been so satisfactorily arranged. Under Campbell’s threat that, should he persist in claiming Adana, the coast of Egypt would be blockaded by the British fleet, he had actually announced his intention of withdrawing his demand, when the news arrived that the Sultan had invested his son with the administration of the territory in dispute.[307] Relations of amity were thus once more officially established between the Sublime Porte and the Pasha.
On May 1 Lord Ponsonby, the newly appointed British ambassador, arrived at Constantinople, preceding by three days Count Orloff, the generalissimo of the Russian military and naval forces in the Black Sea and the Bosphorus, and Ambassador-Extraordinary to the Sublime Porte. His appointment was due to the Tsar’s desire to be represented at Constantinople by some one who could be depended upon resolutely to oppose Admiral Roussin. Boutenieff appears to have been considered as somewhat deficient both in energy and strength of character. Orloff had been furnished with very wide powers, but he was charged to regard the task of convincing the Sultan and his ministers that their safety entirely depended upon the degree of support which, in the future, the Tsar might be disposed to afford them, as the primary object of his mission. He must be admitted to have carried out his instructions most faithfully. From the day of his arrival Russian influence was supreme at the Porte and in the Divan. Roussin’s request that French war ships should be allowed to pass through the Dardanelles was peremptorily refused. Ponsonby saw clearly that, for the time being, he must submit to be overshadowed completely by the Russian ambassador. For the present he could only gaze moodily from his windows at the Russian encampment in the valley of Unkiar-Skelessi and endeavour to restrain his French colleague from affording Orloff any excuse for delaying the departure of his troops. At last, on July 9 and 10, the Egyptian withdrawal behind the Taurus mountains having been completely carried out, the Tsar’s soldiers were embarked and his ships sailed out of the Bosphorus.[308]
For some weeks prior to the departure of the Russian expedition, it had been reported that an offensive and defensive treaty was on the point of being concluded between the Tsar and the Sultan.[309] The truth of this rumour was confirmed after Orloff had quitted Constantinople. It would appear that it was the Sultan himself who first suggested an alliance, at an audience accorded to Orloff shortly after his arrival, and that Ahmed Pasha acted as the intermediary between the palace and the Russian embassy in the very secret negotiations which followed. The diplomatic instrument, known as the Treaty of Unkiar-Skelessi, concluded between the Porte and Russia on July 8, 1833, for a duration of eight years, consisted of six public and one secret article. The public articles merely proclaimed the existence of peace and friendship between the two Empires and provided for their mutual succour in case of need. The whole importance of the treaty lay in the secret clause in which it was stipulated that, inasmuch as Russia had no intention of exercising her right to ask for military assistance, the Porte, in return, would, “upon demand and in accordance with the principle of reciprocity,”[310] close the Dardanelles to the warships of all nations.
It appears that, when it became necessary to inform the Turkish ministers of the projected treaty, they one and all evinced the greatest repugnance to the idea of an alliance with their hereditary enemies. But, at the news that the British fleet was approaching the Dardanelles, they withdrew their objections. They had besought the British government for naval assistance in the struggle with Mehemet Ali, and their request had been refused. The arrival, on June 25, in the Bay of Tenedos of Sir Pulteney Malcolm’s squadron, which, a few months earlier, could have intercepted the communications with Egypt and changed the course of the campaign, now only served to revive painful recollections of Admiral Duckworth’s proceedings in 1807.[311]
The question of access to the sea, which bathes the coasts of the richest provinces of the Empire, must necessarily be a matter of the highest importance to Russia. The principle of regarding the Black Sea as a mare clausum found a place in the treaty concluded between the Porte and Russia, on December 23, 1798. It was again inserted into the treaty of September 23, 1805, but with this important addition—that to the Russian fleet was granted a right of passage to the Mediterranean through the straits. These conditions, however, had been terminated by the outbreak of hostilities in 1806, and in the subsequent treaty of peace, signed at Bucharest on May 10, 1812, no mention was made of the special privilege which Russia had obtained seven years before. Again in the treaty of peace concluded between Great Britain and Turkey, on January 5, 1809, England undertook to observe “the ancient rule of the Ottoman Empire,” which declared the straits of Constantinople closed to the warships of the Powers. But this arrangement, which had ever since been regarded as a law of nations, was suddenly terminated by the act, signed at the palace of Unkiar-Skelessi, restoring Russia to the favoured position which she had enjoyed for a brief space of time in 1805. No specific mention, it was true, had been made of her right of passage to and from the Black Sea to the Mediterranean. Nevertheless, although for obvious reasons both Russian and Turkish ministers might prefer to elude a direct statement on the subject, they unquestionably placed this interpretation upon Orloff’s treaty.[312] It was in this light also that it was looked upon by Lord Palmerston and the Duc de Broglie.
