Outcome : A victory for Russo-Prussian Forces over French Forces [Grande Armee]

Type of battle : Land


Initially only the Reserve Cavalry Corps and Soult's IV Corps came up against what they thought, and because of their messages sent back to him, Napoleon thought, was the Russian Rearguard. Initial attacks were costly and unsuccessful and it was realised that the Russian main body had made a stand. Hastily summoned Napoleon came up with Lannes V Corps and the Imperial Guard. He immediately threw in Lannes Corps in yet another fuitless and costly frontal attack. During this engagement Count Bennigsen, the Russian commander, was so ill that he fell unconscious from his horse several times. The Russo-Prussians retired from the battlefield on the 11th having inflicted heavy casualties on their opponent.
