Silesia, and only made Prince Karol Ferdynand (Władysław's brother) bishop of Wrocław. Neither did Habsburgs provide any help against the Ottoman Empire. The Lisowczycy crushed Transylvanian forces led by George I Rákóczi (Jerzy Rakoczy) at Závada, Humenné District and Humenné (November 13 or 21–24, sources vary; see Battle of Humenné) and started looting, plundering, killing even children and dogs (as a contemporary historian wrote), and burning Eastern Slovakia, thus forcing Bethlen to lift his siege of Vienna and try to save his own lands. Later, the Lisowczycy plagued Silesia and Bohemia and took part in the Battle of White Mountain. The ruler of Moldavia, another vassal of the Ottoman sultan, a hospodar of Italian origin, Gaspar Graziani (Kasper Gratiani in Polish), decided he would be better off under Polish rule and started talks with the Polish king, promising to send 25,000 men. The Polish envoy to Constantinople who arrived in April 1620, was received very coldly. Later Cossack raiding and burning of Constantinople suburbs did not help. The Habsburgs had no qualms about repaying Sigismund's help with treachery. Their envoy actively worked against a new treaty between the Commonwealth and the Ottoman Empire because the Habsburgs knew that any Polish-Ottoman conflict meant less trouble for themselves. This intrigue, coupled with Ottomans annoyance with Commonwealth pro-Habsburg actions and constant attempts by some Polish magnates to gain influence in Moldavia, caused a new war to be unavoidable. In Poland, the king and the hetmans exaggerated the danger in order to recruit more troops and raise taxes for the army. However, the nobles did not trust such measures, and could not be convinced to pay raised taxes for the army, speculating about the reasons behind the expedition. The nobles often thwarted the king's initiatives, even if these could prove to be in the interest of the country at large (including their own long-term purpose), becoming suspicious of any rise in the king's power as a potential reduction of their privileges. The status quo, which translated into their high standard of life, was generally favoured over any alternative. 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
