Emperor Napoleon I of France wins the Battle of Craonne.

The Battle of Craonne was a battle between an Imperial French army under Emperor Napoleon I opposing a combined army of Imperial Russians and Prussians led by Prussian Field Marshal Gebhard Leberecht von Blücher. The War of the Sixth Coalition engagement began when the bulk of Napoleon's army tried to drive Mikhail Semyonovich Vorontsov's 22,000 Russians off the Chemin des Dames plateau to the west of Craonne. After a bitter struggle, Napoleon's attacks compelled Vorontsov's force to withdraw, but French casualties exceeded Russian losses. While the battle raged, Blücher's attempt to turn Napoleon's east flank ended in failure due to poor planning.
