John II Casimir Vasa
King John II Casimir Vasa and the main Polish army left Warsaw on 23 June and had made it to Toporiv in the final days of July when Mikolaj Skrzetuski (called Jan Skrzetuski in Henryk Sienkiewicz's "With fire and Sword") informed the king of the desperate situation at Zbarazh. The king made it to within a half-mile of Zboriv on 13 August.
