Some historians say that King Sigismund decided to intervene in Moldavia because of internal problems caused mainly by the dispatch of Lisowczycy mercenaries to the Habsburg side and their conduct in war. Others point out that some nobles threatened with armed rebellion (rokosz), and, in case of a successful intervention, the king would increase his and the hetman's authority and focus noblemen's attention on external instead of internal problems. Additionally, hetman Żółkiewski, foreseeing confrontation with the Ottoman Empire, preferred to meet their troops on foreign soil.
