Wladyslaw picked Lwow as a rallying point for the campaign against the Tatars, stocking it with artillery, although that may have only been a rumor. These preparations led some to believe that the king was preparing for a government overtaking and the Kraków Senat of July 1646 requested that he stop all preparations, intending to raise that issue at the upcoming council session (Sejm). Being left without support from the parliament, Wladyslaw was only hoping that the Cossacks, nonetheless, were able to "obtain justice for themselves with their own forces".
