In 1787, the Ottomans demanded that the Russians evacuate the Crimea and give up their holdings near the Black Sea, which Russia saw as a casus belli. Russia declared war on 19 August 1787, and the Ottomans imprisoned the Russian ambassador, Yakov Bulgakov. Ottoman preparations were inadequate and the moment was ill-chosen, as Russia and Austria were now in alliance. The Ottoman Empire opened their offensive with an attack on two fortresses near Kinburn, in southern Ukraine. Russian General Alexander Suvorov held off these two Ottoman sea-borne attacks in September and October 1787, thus securing the Crimea. In Moldavia, Russian troops captured the Ottoman cities of Chocim and Jassy. Ochakov, at the mouth of the Dnieper, fell on 6 December 1788 after a six-month siege by Prince Grigori Potemkin and Suvorov. All civilians in the captured cities were massacred by order of Potemkin. Although suffering a series of defeats against the Russians, the Ottoman Empire found some success against the Austrians, led by Emperor Joseph II, in Serbia and Transylvania. By 1789, the Ottoman Empire was being pressed back in Moldavia by Russian and Austrian forces. To make matters worse, on 1 August the Russians under Suvorov attained a victory against the Ottomans led by Osman Pashaat Focsani, followed by a Russian victory at Rymnik on 22 September, and drove them away from near the Râmnicul Sărat river. Suvorov was given the title Count Rymniksky following the battle. The Ottomans suffered more losses when the Austrians, under General Gideon E. von Laudon repelled an Ottoman invasion of Croatia, while an Austrian counterattack took Belgrade. A Greek revolt, which further drained the Ottoman war effort, brought about a truce between the Ottoman Empire and Austria. Meanwhile, the Russians continued their advance when Suvorov captured the reportedly "impenetrable" Ottoman fortress of Ismail at the entrance of the Danube, in December 1790. A final Ottoman defeat at Machin, coupled with Russian concerns about Prussia entering the war, led to a truce agreed upon on 31 July 1791. After the capture of the fortress, Suvorov marched upon Constantinople, where the Russians hoped they could establish a Christian empire. However, as Prof. Timothy C. Dowling states, the slaughters that were committed in the ensuing period somewhat defiled Suvorov's reputation in many eyes, and there were allegations at the time that he was drunk at the siege of Ochakov. Persistent rumors about his actions were spread and circulated, and in 1791 he was relocated to Finland.
Aftermath
Accordingly, the Treaty of Jassy was signed on 9 January 1792, recognizing Russia's 1783 annexation of the Crimean Khanate. Yedisan was also ceded to Russia, and the Dniester was made the Russian frontier in Europe, while the Russian Asiatic frontier—the Kuban River—remained unchanged. The Ottoman war goal to reclaim the Crimea had failed, and if not for the French Revolution, the Ottoman Empire's situation could have been much worse.
