The confederation, encouraged and aided by Roman Catholic France and Austria, declared a war on Russia. Its irregular forces, formed from volunteers, magnate militias and deserters from the royal army, soon clashed with the Russian troops and units loyal to the Polish crown. Confederation forces under Michał Jan Pac and Prince Karol Stanisław Radziwiłł roamed the land in every direction, won several engagements with the Russians, and at last, utterly ignoring the King, sent envoys on their own account to the principal European powers, i.e. Ottoman Empire, the major ally of Bar confederation, France and Austria.
