In speaking of Catherine’s foreign policy we must confine ourselves chiefly to two heads,—the humiliation of Turkey, and the spoliation of Poland. Very soon after her accession, a vacancy in the throne of Poland gave her the opportunity of imposing upon that unhappy nation as its new king one of her former lovers, Stanislaus Poniatowsky, whom she knew, from the weakness of his character, to be a fit instrument of maintaining and increasing her influence. Fear of the aggrandizement of so powerful and hostile a neighbour, and, more especially, jealousy of her designs upon Poland, induced the Porte to declare war against her in 1768. For eight years the contest continued, in all respects to the advantage of the Russians; and during the course of it a Russian fleet (conducted, however, in great measure by British officers) appeared for the first time in the Mediterranean, and signalized its prowess by the total destruction of a superior Turkish armament in the bay of Tchesme, in Lemnos. Not less successful were the Russian arms in the Black Sea, and in Moldavia and Wallachia. Still peace was desirable, even to the victor, from the exhaustion of the contest, and it was concluded in 1774, by the treaty of Kainardgi, upon terms very advantageous to Russia, yet perhaps more favourable than Turkey had cause to expect. The reason of this moderation we shall see presently. The free navigation of the Mediterranean seas and the passage of the Dardanelles were secured to Russia, and the district between the rivers Dnieper and Bog was ceded to her. The Tartars of the Crimea were declared independent, which was nearly equivalent to rendering them tributary to Russia: and in fact that country was formally ceded to Catherine in 1783, by the reigning Cham, and the Porte, unwillingly enough, yielded to that arrangement. But the insulting pomp of Catherine, which almost dared in a moment of bravado to threaten Constantinople itself with an invasion, led to a second war in 1786, which, after a bloody and exhausting conflict, terminated in 1791–2, by the treaty of Jassy, by the farther cession, on the part of Turkey, of the provinces between the Bog and the Dniester, which was declared to be thenceforward the frontier of the two empires. The Russian conquests in Bessarabia, Moldavia, and Wallachia were restored. Memorable in this war, for the desperation of their defence by the Turks, and the awful cruelties which attended their capture by the Russians, were the sieges of the strong fortresses of Oczakow at the mouth of the Dnieper, and Ismail on the Danube. On this occasion again, but for the intervention of other European powers, especially England and Prussia, Catherine might probably have obtained more favourable terms. But the importance of the acquisitions thus made by her on the Black Sea, from the Straits of Kertsh to the Dniester, is not to be measured by their wealth, scarcely by their extent. It was the command
