In the Confederation itself, there were already riots against the French rule, and after the devastation of the French army during the French invasion of Russia, the commander of the Prussian Corps, Yorck, signed a ceasefire with Russia.
Meanwhile, the Prussian rear guard under Yorck took a defensive position between two lakes at the village of Jabel.
Yorck Boyen Insterburg was a German association football club from the city of Insterburg, East Prussia (today Chernyakhovsk, Russia).
