In short: Napoleon Bonaparte entered Moscow expecting a surrender that would end his Russian campaign. Instead, he found a deserted capital engulfed in flames. As the city burned, the French emperor realized his enemy was willing to destroy its most sacred heart rather than allow his army to occupy it.

In June 1812, Napoleon led the Grande Armée, a force of over 500,000 soldiers, into Russia. His strategy relied on rapid movement and decisive strikes, but the Russian forces consistently retreated, employing a scorched-earth policy that denied the French essential supplies. By the time Napoleon reached Moscow on September 14, 1812, the city was largely abandoned; of its 275,000 residents, only a few thousand remained. Napoleon, anticipating that the fall of the capital would force Tsar Alexander to capitulate, settled into the Kremlin.

The situation shifted violently just hours after his arrival. Fires broke out across the city, and reports soon reached Napoleon that Russian agents were intentionally stoking the flames. The city’s fire-fighting equipment had been removed or disabled, and captured Russian military personnel admitted to receiving orders to burn the city. Napoleon himself witnessed the devastation from the Kremlin, narrowly escaping a firestorm that eventually destroyed more than two-thirds of Moscow. The blaze was so immense it was reportedly visible from over 200 versts away.

While some historians and literary figures like Tolstoy have debated whether the fire was a coordinated act of sabotage or the inevitable result of an abandoned, wooden city being occupied by soldiers, the consensus often points to a deliberate scorched-earth strategy. The destruction of Moscow left the French army without shelter or provisions as winter approached. After waiting a month for a surrender that never materialized, Napoleon was forced to retreat. The disastrous journey back, marked by starvation, subzero temperatures, and constant harassment from Russian forces, effectively shattered the Grande Armée and set the stage for Napoleon’s eventual defeat and exile.
