Russo Turkish War 1711

Pruth River Campaign The Russo-Ottoman War of 1710–11, also known as the Pruth River Campaign after the main event of the war, erupted as a consequence of the defeat of Sweden by the Russian Empire in the Battle of Poltava in the summer of 1709 and the escape of the wounded King Charles XII of Sweden and his large retinue to the Ottoman fortress of Bender. Sultan Ahmed III declined incessant Russian demands for Charles's eviction, prompting Tsar Peter I of Russia to attack the Ottoman Empire, which in its turn declared war on Russia on 20 November 1710. Concurrently with these events, the Prince Dimitrie Cantemir of Moldavia and Tsar Peter signed the Treaty of Lutsk (13 April 1711), by which Moldavia pledged to support Russia in its war against the Ottomans with troops and by allowing the Russian army to cross its territory and place garrisons in Moldavian fortresses. After having gathered near the Moldavian capital Iași, the combined Russo-Moldavian army started on 11 July the march southwards along the Prut River with the intention of crossing the Danube and invading the Balkan peninsula.
