The districts south of the old Roman earthworks which link the Dniester with the Pruth along the line of the Botna, just south of Bender, consist of level pastureland known as the Budjak steppes.
Limit of the ante-steppe is represented by a line drawn from the Pruth through Zhitomir, Kursk, Tambov and Stavropol-on-Volga to the sources of the Ural river.
During the unlucky campaign of 1711, he succeeded against all expectations in concluding the peace of the Pruth (see Turkey: History).
Negotiations for peace were now opened and on the 21st of July - chosen by the Russian plenipotentiary as the anniversary of the humiliating convention of the Pruth - the treaty of Kuchuk Kainarji was signed.
Having annihilated at Poltava the army of Charles XII., Peter was not at all indisposed to renew the struggle with Turkey, and began the campaign in the confident hope of making extensive conquests; but he had only got as far as the Pruth when he found himself surrounded by a great Turkish army, and, in order to extricate himself from his critical position, he had to sign a humiliating treaty by which Azov and other conquests were restored to the sultan.
Of undulating country separate the Dniester from the margin of the Carpathian chain, and in this space the Palaeozoic floor sinks far beneath the surface, so that not even the deep-cut valley of the Pruth exposes any beds of older date than Miocene.
The Turks succeeded in surrounding Peter the Great near the Pruth, and his army was menaced with total destruction, when the Turkish commander, the grand vizier Baltaji Mahommed Pasha, was induced by the presents and entreaties of the empress Catherine to sign the preliminary treaty of the Pruth (July 21, 1711), granting terms of peace far more favourable than were justified by the situation of the Russians.
The Pruth and Sereth are navigable for a short distance by small sailing craft; the conservancy of the Danube (q.v.) is controlled by a European commission, which sits at Galatz.
Athanaric next attempted to establish himself in the territory between the Pruth and the Danube, and with this object set about heightening the old Roman wall which Trajan had erected in north-eastern Dacia; before his fortifications, however, were complete, the Huns were again upon him, and without a battle he was forced to retreat to the Danube.
