Several different visions of the campaign and political goals clashed in the Polish camp. Some of the former members of the Zebrzydowski Rebellion, opponents of Sigismund, actually advanced proposals to have Sigismund dethroned and Dmitriy, or even Shuyski, elected king. Żółkiewski, who from the beginning opposed the invasion of Russia, came into conflict with Sigismund over the scope, methods, and goal of the campaign. Żółkiewski represented the traditional views of Polish nobility, the szlachta, which did not support waging aggressive and dangerous wars against a strong enemy like Russia. Thus Żółkiewski favored the plans for peaceful and voluntary union, much like that with Lithuania. Żółkiewski offered Russian boyars rights and religious freedom, envisioning an association resulting in the creation of the Polish–Lithuanian–Muscovite Commonwealth. To that end, he felt that Moscow's cooperation should be gained via diplomacy, not force. Sigismund III, however, did not want to engage in political deals and compromises, especially when these had to include concessions to the Orthodox Church. Sigismund was a vocal, almost fanatical, supporter of the Catholic Church and counter-reformation, and believed that he could win everything and take Moscow by force, and then establish his own rule along with the rule of Roman Catholicism.
