Which battle in Leo Tolstoy’s War and Peace is fought on 7 September 1812?

The battle in Leo Tolstoy’s War and Peace fought on 7 September 1812 is the Battle of Borodino.

Borodino was the largest and bloodiest single-day battle of Napoleon’s 1812 invasion of Russia. It pitted Napoleon Bonaparte’s Grande Armée against the Russian army commanded by Mikhail Kutuzov. The battle took place west of Moscow and ended without a simple decisive victory, although the Russians withdrew afterward.

Tolstoy devotes a major section of War and Peace to Borodino. His narrative challenges the idea that one heroic commander controls the course of history. Instead, he emphasizes confusion, countless individual decisions, and the movement of enormous armies.

The date can cause confusion because Russia used the Julian calendar in 1812. The battle was 26 August in the Old Style calendar and 7 September in the Gregorian calendar. Napoleon later entered Moscow, which the Russians had abandoned.
