As the Polish winter is in full swing, Napoleon is in pursuit of the Russians who are under the command of the timid Bennigsen. This one seeks to protect the city of Königsberg and retreats in front of the French. In the battle of Hoff, the French heavy cavalry particularly stood out, then the fight of Ziegelhoff, in front of Eylau, was only the prelude to one of the most terrible battles of the Empire. On February 8, 1807, the French and Russian armies met in front of the small town of Preussich-Eylau. Although outnumbered, the French resist the might of the Russian artillery. The bravery of the troops of Davout's 3rd Corps, the deadly heroism of Augereau's 7th Corps and the large cavalry charge led by Murat and Bessières are the major episodes of this battle, which unfolds more complex than there is. appears. A battlefield located in the Kaliningrad enclave and, long closed to visitors, Eylau therefore finds its place in the "forgotten battles".
