Important and urgent news from Constantinople then forced the Prince to bring his tour to an end, and Cotroceni, near Bucharest, was reached on September 7, after some 920 miles had been traversed in seventeen days by means of about 3000 post-horses. The result of the journey was altogether favourable, for not only had the Prince gained a clearer insight into the affairs of Moldavia, but the Separatist faction had been considerably weakened by the intercourse of Prince Charles with the leading men of the Principality.
The following day the Prince received the English and French Consuls, who came to advocate compliance with the demands of the Sublime Porte, which, though couched in far more moderate language, still contained the disputed clauses of the former project. The Ministry thereupon decided to send Ministers Stirbey and Sturdza to Constantinople to negotiate better terms for Roumania.
The Prince received a letter from his father on September 14, 1866, containing the following significant paragraph:
"The political horizon is still very overcast; a war with France is unavoidable, although it will not take place this year. The 'chauvinism' of the French Press is colossal, and the Emperor, who is personally inclined for peace, will probably have to give way to the pressure!..."
The news from Constantinople now became more favourable, as both General Ignatieff and the Marquis de Moustier brought pressure to bear on Ali Pacha in favour of Roumania. Moreover, the condition of Crete, where an insurrection had broken out, aided and instigated by Greece, was in itself a reason why the Porte should come to a definite settlement with Roumania. Negotiations, however, suffered further delays owing to the departure of the Marquis de Moustier and the renewal of impossible demands by Ali Pacha, who was now supported by England and France. The last named believed that Prussian influence caused the Prince's reluctance to comply with the Emperor Napoleon's advice and proceed to Constantinople before receiving recognition by means of a firman, and the relations of Roumania to France became consequently cooler. The whole affair turned upon the words, "partie intégrale de mon Empire," which the Roumanian Ministry refused at first to accept, but now sought to modify by the addition of "dans les limites fixées par les capitulations et le Traité de Paris." This addition was at last agreed to by Ali Pacha, and the long struggle ended on October 20. An exchange of letters, as recommended by the French Ambassador, then took place between the Grand Vizier and Prince Charles, who announced his intention of proceeding to Constantinople to receive the firman from the hands of the Sultan.
The Prince granted an audience to the Consuls of the Powers on the following day to receive the congratulations of their Governments upon his recognition by the Porte before setting out on his journey to Constantinople. At Rustchuk the Governor of the Danubian vilayet, Midhat Pacha, received the Prince with the utmost ceremony. On arriving at Varna Prince Charles embarked at once on the Imperial steam yacht Issedin, which had brought Djemil Pacha and Memduh Bey to escort him to the Golden Horn.
On his arrival at Constantinople the Prince landed at Beglerby, where an imperial palace had been destined for his reception. Thence the Prince, in the uniform of a Roumanian general, proceeded to Dolma Bagdsche, where the Sultan came to the door of his cabinet to welcome him. Next the sofa on which the Sultan was to sit a chair was placed for the Prince, but he pushed it gently aside, and as a Prince of Hohenzollern sat down next to his Suzerain. The conversation which then ensued turned first upon the Prince's journey, and afterwards on the state of affairs in Roumania. At the conclusion of the audience the Sultan handed Prince Charles a paper, which he laid on the table without looking at it, and then asked for permission to present his suite, one of whom took charge of the firman. The Sultan took a hearty leave of the Prince, who then visited the Sublime Porte, where the Grand Vizier welcomed him and presented to him the various Turkish great dignitaries of the Ottoman Empire.
On October 26 Prince Charles received the Ambassadors of the Powers, amongst their number Lord Lyons, who had been of material assistance in obtaining the recognition of the Prince, but who was strongly opposed to any slackening of the bonds between Turkey and the Vassal States.
The impression left in the Prince's mind by the magnificent reception was that it was due more to his descent from the House of Hohenzollern than to the fact that he was ruler of Roumania, for the Hospodars had been treated merely as highly placed officials, and as a symbol of their vassaldom were obliged to hold the Sultan's stirrup as he mounted.
