 This cooled France's relations with Poland, as Sobieski abandoned his pro-French stance.The Polish-French alliance had completely fallen apart by 1683 when some of the pro-French faction members within Poland were accused of plotting to overthrowing Sobieski, and French ambassador Nicolas-Louis de l'Hospital, Bishop of Beauvais and Marquis of Vitry was forced to leave the country.The failure of this plan prompted the king to promote Prince James through participation in the war against the Ottoman Empire.
