Korecki, despite initial successes, was defeated by the Ottoman-Tatar-Moldavian army in the Battle of Cornul lui Sas in 1616, after which he was captured and imprisoned in Yedikule prison.

Samuel Korecki married the daughter of Moldavian hospodar Ieremia Movilă, famous for her beauty Catherine, which drew him and his wife's brothers-in-law into dynastic struggles in Moldavia and Wallachia.

In view of this, the throne fell to Ieremia's brother Simion, who after less than a year in power died under not entirely clear circumstances.

The Polish nobility intervened in the war, Stanisław Zolkiewski stood up for Mikhail and the Potocki and Wiśniowiecki families stood up for Elisabeta, and in 1607 a private army of the Potocki family marched into Moldavia, defeating the opposition at the battle of Stefanesti and placing Elisabeth's eldest son Constantin on the throne.

[3] Soon after, in 1615, Korecki together with Michał Wiśniowiecki and Alexandru embarked on an armed expedition to the Moldavian capital of Iași where they smashed Tomsa's army.

And soon after the victory, in order to consolidate the alliance, Korecki married Catherine Movila daughter of Ieremia Movilă.

[1][5] The change of power was opposed by the Ottoman Sultan Ahmed I who ordered his other subject, the Wallachian voivode Radu Mihnea, to remove Alexandru from the throne.
