Battle of Eylau, Prussia, 1807: Napoléon orders a cavalry assault by Murat
The Battle of Eylau or Battle of Preussisch-Eylau, 7 and 8 February 1807, was a bloody and inconclusive battle between Napoleon's Grande Armée and the Imperial Russian Army under the command of Levin August von Bennigsen near the town of Preussisch Eylau in East Prussia. Late in the battle, the Russians received timely reinforcements from a Prussian division of von L'Estocq. After 1945 the town was renamed Bagrationovsk as a part of Kaliningrad Oblast, Russia. The engagement was fought during the War of the Fourth Coalition, part of the Napoleonic Wars. Of all Napoleonic battles, this is considered to be the most uncertain and mysterious for several reasons--mainly the strength of Murat's reserve cavalry.
