The Battle of Boroino (Russian: Бородинская битва Borodinskaja bitva, French: Bataille de la Moskowa), fought on September 7, 1812, was the largest and bloodiest single-day action of the Napoleonic Wars, involving more than 250,000 troops and resulted in at least 70,000 total casualties. The French Grande Armée under Emperor Napoleon I attacked the Imperial Russian army of General Mikhail Kutuzov near the village of Borodino, west of the town of Mozhaysk, and eventually captured the main positions on the battlefield, but it failed to destroy the Russian army.
