[Sidenote: Powers save Turkey] [Sidenote: Russia's hold on Turkey] In the Balkans Russia's war with Turkey was waged with vigor. The winter months had been spent in bringing up reserves. The Czar withdrew from interference at headquarters, and Wittgenstein was superseded by General Diebitsch, a trained Prussian soldier. This general made preparations to cross the Balkans as soon as Silistria should have fallen, without waiting for the fall of Shumla. On the other side of the Balkans the Russian fleet made a diversion so as to prepare the way for joining forces on the banks of the Black Sea. In accordance with these plans Diebitsch sent a strong force against Silistria. Before anything had been effected in front of Silistria, Reshid Pasha, the Turkish Grand Vizier, moved eastward from Shumla and took the field against the weak Russian forces at Varna. He lost time, however, and suffered himself to be held at bay by the Russians. Diebitsch hurried across Bulgaria in forced marches. Coming up in Reshid's rear he could either fall upon Shumla or force the Turks to open battle. He chose the latter course. The Turks, harried in their rear, attempted to regain the roads to Shumla. On June 10, the two forces met in a pitched battle at Kulevtcha. Reshid was badly defeated, losing 5,000 men and forty-three guns, but made good his retreat to Shumla. Diebitsch had to lay siege to Shumla. Soon after this, Silistria fell into the hands of the Russians. Turning Varna over to the Bulgarians, and leaving a blockading force before Shumla, Diebitsch boldly crossed the Balkans. The resistance of the Turks was weak. On August 19, the Russians appeared before Adrianople. In the Black Sea the Russian frigate "Mercury" defeated two Turkish men-of-war. The Turks were seized with terror. Adrianople surrendered without a blow. In the Morea the Turks evacuated Tripolitza and Missolonghi and acknowledged the independence of Greece. The ports of the Black Sea, almost as far south as the Bosphorus, fell into Russian hands. Flying columns of the Russian army penetrated down to the AEgean coast and as far as the Euxine. Yet the Russians were so weak in numbers that anything like determined resistance could easily have checked them. As it was, all Turkish resistance collapsed before the Russian onward march toward Constantinople. The Sultan appealed to the Powers for help. England and Austria intervened, and peace was forced upon Russia. The treaty of Adrianople, signed on September 14, confirmed to Russia its protectorate over the Danubian principalities. No Mussulman was to be permitted to stay within the principalities, and all Turkish lands were to be sold within eighteen months. No fortified point on the left bank of the Danube was left to Turkey. Territory in Asia was ceded to Russia, as well as the ports of Poti and Anapa on the Black Sea. The waters of this sea were thrown open to international navigation; and the straits of Constantinople and the
