The Russo-Ottoman War of 1710–1711, also known as the Pruth River Campaign, was a brief military conflict between the Tsardom of Russia and the Ottoman Empire. The main battle took place during 18-22 July 1711 in the basin of the Pruth river near Stănilești after Tsar Peter I entered the Ottoman vassal Principality of Moldavia, following the Ottoman Empire’s declaration of war on Russia. The ill-prepared 38,000 Russians with 5,000 Moldavians, found themselves surrounded by the Ottoman Army under Grand Vizier Baltacı Mehmet Pasha. After three days of fighting and heavy casualties the Tsar and his army were allowed to withdraw after agreeing to abandon the fortress of Azov and its surrounding territory. The Ottoman victory led to the Treaty of the Pruth which was confirmed by the Treaty of Adrianople.

The Prut is a 953 km (592 mi) long river in Eastern Europe. It is a left tributary of the Danube. Part of its course forms Romania's border with Moldova and Ukraine.
