The Battle of Friedland (June 14, 1807) was a major engagement of the Napoleonic Wars between the armies of the French Empire commanded by Napoleon I and the armies of the Russian Empire led by Count von Bennigsen. Napoleon and the French obtained a decisive victory that routed much of the Russian army, which retreated chaotically over the Alle River by the end of the fighting. The battlefield is located in modern-day Kaliningrad Oblast, near the town of Pravdinsk, Russia. On June 19, Emperor Alexander sent an envoy to seek an armistice with the French. Napoleon assured the envoy that the Vistula River represented the natural borders between French and Russian influence in Europe. On that basis, the two emperors began peace negotiations at the town of Tilsit after meeting on an iconic raft on the River Niemen.
