After Napoleon’s triumph at Austerlitz, a new war loomed on the horizon. In 1806, Prussia confronted the growing French ambitions in the War of the Fourth Coalition. It proved to be a mistake as Napoleon routed the Prussian army barely two weeks into the war. After humiliation of Prussia, on the battlefield at Jena, the French Emperor turned his attention to subduing his Russian foe and marched into Poland in the winter of 1806. Six months later, the Russians had been beaten and brought to the peace table and Napoleon was at the height of his powers.
