Obedience to the King and death
He was a supporter of a strong and centralized royal power (limiting Liberum Veto), and supported the concept of a successor of the throne with the current King being still alive (Vivente Rege – a kind of Royal election). At the command of the King wanted to solve the issue of the Fraternal Association, an insurrection created by some long unpaid members of the army claiming the termination of obedience to the King (at the beginning for economic reasons, but later, considering any limitation to Liberum Veto and Vivente Rege proposal as "treason" to Commonwealth constitutional laws). In July 1662, he went to Vilnius for talks with the rebel troops in Lithuania. There he was treacherously captured by Konstanty Kotowski, Deputy Speaker of the Fraternal Association, which is thus intended to prevent any agreement that may in effect resulted in the termination of the insurrection. Wincenty Korwin Gosiewski was shot to death on 29 November 1662 near Ostrynia [=Astryna]. Later, the perpetrators of the murder were sentenced to death.
