Napoleonic Wars: The French Grande Armée enters Moscow. The Fire of Moscow begins as soon as Russian troops leave the city.

The Napoleonic Wars (1803–1815) were a global series of conflicts fought by a fluctuating array of European coalitions against the French First Republic (1803–1804) under the First Consul followed by the First French Empire (1804–1815) under the Emperor of the French, Napoleon Bonaparte. The wars originated in political forces arising from the French Revolution (1789–1799) and from the French Revolutionary Wars (1792–1802) and produced a period of French domination over Continental Europe. The wars are categorised as seven conflicts, five named after the coalitions that fought Napoleon, plus two named for their respective theatres: the War of the Third Coalition, War of the Fourth Coalition, War of the Fifth Coalition, War of the Sixth Coalition, War of the Seventh Coalition, the Peninsular War, and the French invasion of Russia.

The Grande Armée was the primary field army of the French Imperial Army during the Napoleonic Wars. Commanded by Napoleon, from 1804 to 1808 it won a series of military victories that allowed the First French Empire to exercise unprecedented control over most of Europe. Widely acknowledged to be one of the greatest fighting forces ever assembled, it suffered catastrophic losses during the disastrous French invasion of Russia, after which it never recovered its strategic superiority and ended its military career with a total defeat during the Hundred Days in 1815.

During the French occupation of Moscow, a fire persisted from 14 to 18 September 1812 and all but destroyed the city. The Russian troops and most of the remaining civilians had abandoned the city on 14 September 1812 just ahead of French Emperor Napoleon's troops entering the city after the Battle of Borodino. The Moscow military governor, Count Fyodor Rostopchin, has often been considered responsible for organising the destruction of the former capital to weaken the French army in the scorched city even more.
