After the disaster of the German campaign and the defeat of Leipzig (1813), the armies of the Sixth Coalition converge on the France of Napoleon I. Before and during the campaign in France, the emperor's soldiers will fight in Holland, Belgium and northern France. During these little-known episodes, two characters will shine: Lazare Carnot, in charge of the defense of the port of Antwerp and General Maison who is fighting between Brussels and Lille. This campaign will see Holland become again the Kingdom of the Netherlands and Belgium live a few months of independence before being attached, by decision of the Congress of Vienna (1815), to the Netherlands. These two countries will live the years 1813-1814 under the yoke of their Russian and Prussian liberators leading the inhabitants to name this period the “Cossack years”.
