Napoléon à la Bataille d’Eylau par Antoine-Jean Gros
The Battle of Eylau or Battle of Preussisch-Eylau, 7 and 8 February 1807, was a bloody and inconclusive battle between Napoléon’s Grande Armée and a Russian Empire army under Levin August, Count von Bennigsen near the town of Preußisch Eylau in East Prussia. Late in the battle, the Russians received a timely reinforcement from a Prussian division. The town is now called Bagrationovsk and it is a part of Kaliningrad Oblast, Russia. The engagement was fought during the War of the Fourth Coalition, part of the Napoleonic Wars.
Napoleon’s armies previously smashed the army of the Austrian Empire in the Ulm Campaign and the combined Austrian and Russian armies at the Battle of Austerlitz on 2 December 1805. Austerlitz forced the Austrians to sue for peace and their Russian allies to withdraw from the conflict. On 14 October 1806, Napoleon crushed the armies of the Kingdom of Prussia at the Battle of Jena-Auerstedt. After a rapid pursuit, the broken pieces of the Prussian army were destroyed at the Battles of Prenzlau and Lübeck and in a series of capitulations at Erfurt, Pasewalk, Stettin, Magdeburg, and Hamelin. Eylau was the first serious check to the Grande Armée and the myth of Napoleon’s invincibility was badly shaken.
