On 14 June Napoleon obtained an overwhelming victory over the Russians at the Battle of Friedland, wiping out the majority of the Russian army in a very bloody struggle. The scale of their defeat convinced the Russians to make peace with the French. On 19 June, Tsar Alexander sent an envoy to seek an armistice with Napoleon. The latter 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. The very first thing Alexander said to Napoleon was probably well-calibrated: "I hate the English as much as you do". Their meeting lasted two hours. Despite waging wars against each other the two Emperors were very much impressed and fascinated by one another. “Never,” said Alexander afterward, “did I love any man as I loved that man.”
