The Treaty of Jassy in January 1792 ended the Russian war with the Ottomans, and in April, the First Coalition wars began, forcing Prussia to move the bulk of its forces west to deal with Revolutionary France. Russia, angered by Poland's attempt to move out of its influence, invaded Poland in May. Around then, Prussian policy was already set against Poland. Rather than discussing how to aid it, Frederic Wilhelm and his ministers were discussing how to convince Austria and Prussia to a new partition. Lucchesini has already made several declarations that Prussia could not aid the Commonwealth, and in June that year, Potocki's mission to Berlin received a confirmation, motivated on the grounds that the 3 May Constitution changed Poland so much that Prussia did not consider its obligations binding. Prussian Foreign Minister Friedrich Wilhelm von Schulenburg-Kehnert clearly and with rare candor told Potocki that Prussia did not support the constitution but could not say so initially to avoid any Polish-Russian reconciliation and would not help even as a mediator, as it is not in Prussian's interest of the state to see Poland so strengthened that it could later threaten Prussia.
