The Moldavian campaign of the Polish–Ottoman War of 1683–1699 was launched by the Polish–Lithuanian Commonwealth led by the Polish king, Jan III, in order to control Moldavia.

After the victory at the Battle of Vienna, the Polish king, Jan III, decided to continue the war to oust the Ottomans from Europe.

[1][2] In fall 1683, the Polish king appointed Stefan Kunicki as the leader of a campaign to oust the Ottomans from Moldavia [ru; uk].

[1] In April 1684, Jan made plans to launch another Moldavian campaign by conquering the Danube river mouth.

On September 4, the construction of a bridge to cross the Dniester had begun, which was complicated by the rain and strong winds, as well as battles with the Crimean troops.

The King dispatched a force to build another crossing near Gródek; however, the Polish army would face the Crimeans in bloody battles, which would slow down their march.

Large Ottoman-Crimean forces approached the Dniester, and famine and disease began in the Polish army.

[4][3][5] Pope Innocent XI demanded the Polish king more vigorous action against the Ottoman front.

The Polish king, facing serious difficulties during the siege, preferred to march against Moldavia, hoping not only to obtain territory but to cut off supplies from Kamenets.

Five days earlier, the Polish received information of an Ottoman army of 15,000 led by Sulieman Pasha concentration at Țuțora who were delivering supplies to Kamenets.

At this time, the Ottomans decided to change their plan, and instead of heading towards Kamianets they turned towards the enemy reaching from the west.

[3] Thus ended the Moldavian campaign of 1685, an unsuccessful expedition due to lack of instruction by the king or the Senate.

The unfortunate treaty's settlements needed to be delayed, or better yet, rejected completely, in order for the Polish monarch to obtain a military and political edge over Russia.

The advantage would be assured if he subjugated Moldavia and Wallachia and installed Prince Jakub on the throne of one of the aforementioned nations.

[9][3][10] The Polish assembled an army of 36,000 men and 88 cannons, supported by a small number of foreign officers, mainly French and German.

The Polish side gave up on trying to conquer Moldavia in the future and instead concentrated on trying, albeit unsuccessfully, to take Kamenets back from the enemy.

[3] Following little participation from Poland in the war for some years, the Polish king, Jan III, decided to turn to Austria again in 1691.

The king initially achieved success, he managed to capture Soroca and Suceava and routed a detachment of Ottoman-Crimean forces on September 13 near Pererîta.

[3][5] The Polish king issued a manifesto stating:[5] For the second time, we are not going to this land for another, but only to give our hand and salvation to these countries, which belong to faith, unity, and Christian community and have fallen under the domination of the filthy against their will.However, the Moldavian prince, Constantin Cantemir, refused to ally with the Poles.

The gentry's desire for peace prevented many people from accepting John III's plans for Moldavia and Wallachia; instead, they were viewed as Sobieski's dynastic interests rather than those of the state.

[5] The old and sick king was losing more and more energy, and Queen Marie Casimire Sobieska took the helm of government from his weakening hands.

Poland's military and diplomatic activity fell sharply, while others collected the fruits of the Viennese victory.
