Hassan, after this successful exploit, was made Capitan Pasha of the Ottoman navy. He managed to collect together another fleet, and engaged the Russian fleet again off Mondreso. Both fleets claimed victory, but it would seem that the Russians had the worst of it, for they sheered off and left these waters. When next heard of, the Russian fleet was engaged in giving support to Ali Bey, the head of the Mamelukes of Egypt, who had risen in rebellion against the Turkish pasha there, and who was now invading Syria. Orloff landed four hundred soldiers in Syria in support of this rebel. But Ali Bey soon found himself in difficulties. An outbreak took place in his own army against him, fomented by his brother-in-law. Ali Bey was defeated and put to death, and the four hundred Russians were slain in battle. The Porte for a time recovered its hold on Egypt.
The story of Orloff’s expedition has been told as it is a good illustration of the use of a naval force which can command the sea in a war of this kind, and of its inability to undertake operations on land, or to force its way against land batteries, unless supported by an adequate army. Orloff’s fleet remained in the east of the Mediterranean till the close of the war in 1773, but it did not effect anything of importance.
Reverting to the military operations on the Danube, the autumn campaign of 1770 was very unfavourable to the Ottoman cause. Khalil Pasha, who was now in command, proved himself to be no more competent than his predecessor. Romanzoff, in command of the Russian army, overran the whole of Moldavia. Khalil led thirty thousand efficient soldiers and a host of Tartar irregulars against him. The two armies came in contact at Karkal, where Khalil entrenched himself in front of the Russians, while his Tartars ravaged the country behind them and threatened their communications. Romanzoff then stormed the Turkish line. The Turks fled in panic. Their camp and guns and immense stores fell into the hands of the Russians. The surviving Turks recrossed the Danube. At the close of the campaign of 1770 all the Turkish fortresses north of the Danube were in the hands of the Russians. The Grand Vizier’s army was practically destroyed. Only two thousand men were left to him under arms.
In the following year, 1771, still greater disasters attended the Turks. Prince Dolgorouki, at the head of eighty thousand Russians and sixty thousand irregular Tartars, invaded the Crimea after storming successfully the lines of Perekop. The whole province was overrun. Kertch and Yenikale were captured. Wallachia and Moldavia successively fell into the hands of the Russians. Khoczim and Jassy were captured. The only gleams of success to the Turks in this campaign were the recovery of Giurgevo on the Danube and the successful defence of Oczakoff and Kilburn on the shores of the Black Sea. In the Caucasus the Russians were also successful and drove the Turks from Georgia and Mingrelia.
These repeated successes of the Russians began to cause alarm to Austria and Prussia, who by no means wished for the undue aggrandizement of their neighbour. They therefore attempted negotiations with Russia for mediation on behalf of the Ottoman Empire. But the Empress Catherine obstinately resisted anything in the way of interference by other Powers, and made it known to the Sultan that terms of peace must be settled with herself alone. In his desperation the Sultan proposed to Austria a joint partition of Poland as a bribe for assistance against Russia, oblivious of the fact that he had entered upon war with Russia on behalf of Poland. The offer was declined by the Emperor, not because he had any objection to a scheme of plunder, but because he did not consider the Porte to be in a position to become an effective partner in such a scheme. As a matter of fact, Austria, Russia, and Prussia were continually negotiating schemes for the dismemberment either of Poland or Turkey, as might be most convenient to them.
At the end of the campaign of 1771 an armistice was agreed to between Russia and the Porte, and the greater part of the following year was occupied in discussing terms of peace at a conference or congress at Bucharest. An ultimatum was eventually presented by Russia, embodying terms of what might seem to be a very moderate character, in view of the great success of her armies and the extent of territories which they had practically conquered. The Sultan himself and his Grand Vizier and principal ministers and generals were in favour of accepting the terms as offered, but the Mufti and the whole body of the ulemas were vehemently opposed to them. The Divan therefore rejected them and war was renewed. As these terms did not substantially differ from those which were accepted two years later, it is not worth while at this stage to explain them.
Meanwhile there had been for more than a year a suspension of hostilities, and a breathing time had been afforded to the Porte, during which strenuous efforts were made for another campaign. At the end of 1772, Mouhsinzade Pasha, who had so distinguished himself in the defence of the Morea, was again appointed Grand Vizier. He infused new vigour into the army. In the spring of 1773, when the negotiations at Bucharest were brought to a conclusion, hostilities were recommenced. The campaign in Europe, in this year, was confined within the quadrilateral formed by the fortresses in Silistria and Rustchuk on the Danube, the city of Varna on the Black Sea, and the great fortress of Schumla to the north of the Balkan range. There were several engagements between divisions of the two armies in this district, in which the Turks were generally worsted, but these victories were not of much avail to the Russians so long as the three great fortresses of Silistria, Varna, and Schumla remained in the hands of the Turks.
The two main features of the campaign were the successful defences by the Turks of Silistria and Varna against overwhelming forces of Russians. General Romanzoff crossed the Danube early in the year near Silistria. He defeated a Turkish division and compelled it to retreat to that fortress, where it added to its garrison. Romanzoff then laid siege to it. His army stormed the outer defences with the utmost vigour and succeeded in forcing them. But their difficulties only then commenced. The Turks, under command of Osman Pasha, maintained an heroic resistance. The whole male population turned out in aid of the army. They fought the advance of the Russians street by street. In the end the Russians were compelled to retreat, after the loss of eight thousand men. Later, Romanzoff inflicted a severe defeat on the Turks at Korason. This opened the way to Varna. But here again a successful defence was offered by the Turkish garrison, supported by the seamen of the Ottoman fleet in the Black Sea. This was the closing scene of the campaign of 1773. Sultan Mustapha died towards the close of this year, and was succeeded by his brother, Abdul Hamid, who had been secluded in the Cage for forty-eight years. As was to be expected, he showed no capacity for the position to which he was now at last called. He was, however, favourable to peace, as was also Mouhsinzade, who was maintained as Grand Vizier.
At the commencement of the campaign of 1774 the Grand Vizier issued from his camp at Schumla with twenty-five thousand men, with the intention of taking the offensive and attacking the Russians at Hirsova, on the Danube. The Russian forces in that district were under command of Suvorov, who now and later was to show himself the greatest general Russia had as yet produced. He did not wait to be attacked by the Turks. He advanced from Hirsova and met the Grand Vizier’s army at Kostlidji, where he gained an overwhelming victory. The Turkish camp and all its guns and stores were captured. The defeated army dispersed, and the Grand Vizier found himself with only eight thousand men to defend Schumla. The Russians manœuvred so as to cut off the communications of Schumla with the capital. Mouhsinzade thereupon asked for an armistice. This was refused by the Russians, but they were willing to discuss terms of peace. The assent of the Porte was obtained by the Grand Vizier, and on July 16, 1774, after seven hours only of discussion between plenipotentiaries at the village of Kainardji, a treaty of peace was agreed to.
