The Battle of Borodino, fought on September 7, 1812, was the largest and bloodiest battle of the French invasion of Russia, involving more than 250,000 troops and resulting in at least 70,000 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 failed to destroy the Russian army. About a third of Napoleon's soldiers were killed or wounded; Russian losses, while heavier, could be replaced due to Russia's large population, since Napoleon's campaign took place on Russian soil."
