Battle of Arcis-sur-Aube
The Battle of Arcis-sur-Aube (20–21 March 1814) saw an Imperial French army under Napoleon face a much larger Allied army led by Karl Philipp, Prince of Schwarzenberg during the War of the Sixth Coalition. On the second day of fighting, Emperor Napoleon suddenly realized he was massively outnumbered, and immediately ordered a masked retreat. By the time the Austrian Field Marshal Schwarzenberg realized Napoleon was retreating, most of the French had already disengaged and the Allied pursuit afterwards failed to prevent the remaining French army from safely withdrawing to the north. This was Napoleon's penultimate battle before his abdication and exile to Elba, the last being the Battle of Saint-Dizier.
