THE GREAT EUROPEAN WAR II

The year of 1836 would bring the poisoned fruits of decades of French domination of Central Europe ever since the Austrian defeat in 1809. The death of the cautious King Ludwig I during the new year celebrations in the palace (under suspicious circumstances while he slept) would bring the rule of his son Heinrich I and the old pro-war faction that was kept in check for most of Ludwig’s rule. In a similar manner, Archduke Franz II would drop dead less than a month later and give the throne to the new Archduke Ferdinand. The year had barely started but these two new “casualties” would intensify the war greatly, just as the Coalition seemed to be losing vigor and morale after the battles of Pinsk and Batumi, Napoleon II would have to deal with treason inside his system, including from his own marshals.
Jean-Baptiste Bernadotte was one of Napoleon’s Marshals during the Third and Fourth coalitions, until he was elected as Prince of Sweden in 1810, becoming enamored with his new land. He would be crowned King Karl XIV of Sweden, and rule his country for decades as a loyal member of the Continental system, yet there would be tensions between France and Sweden over the status of Swedish Pomerania, which was invaded by the French in 1835. The Swedish population would be furious with such illegal invasion, and the King felt betrayed that the petulant boy in Paris considered Sweden only a stepping stone, as such he started secret negotiations with Russia, where the Russian Empire offered to sell back the island of Åland in return that the Sweden joined the coalition. The King would accept, and on the 12th of February of 1836 Sweden at last joined the war... by bombarding Christiania and crossing the Norwegian border and declaring war on the Continental Alliance. The enraged Emperor would order Prussian fusiliers to invade the island of Rügen, instead the Prussian army launched dual attacks against Poznan and Mecklenburg, betraying the French on the 14th of February, and on the very next day, Austrian forces would invade Hungary and Illyria, laying siege to Trieste by the 20th.
The sudden betrayal of the 3 nations cut the Poles, Hungarians, and Ottomans from the rest of the Alliance. In a matter of weeks, Prussian and Austrian forces would take the Illyrian provinces, Saxony, Mecklenburg, Danzig and Poznan. But as April came, the Alliance would recover from the shock and the forces of the “Rheinbund” another Grande Armee would march to the west, first hoping to take out Austria and swinging North to Berlin. The French forces would be led by a new generation of military officers after 16 years of peace, trained in the lessons of the Napoleonic Wars with many being veterans of these wars. The “Armee d’Allemagne” would be led by Marshal Charles-Eugene Mercer, member of the post-revolutionary generation of Frenchmen, born in 1792 in Reims and one of the most gifted students of the Military Academy.
The German campaign would follow the footsteps of the 1809 French campaign, advancing through the Danube in Bavaria and heading straight to Vienna. The Austrians expected such a move, creating several lines of defense near the city, forcing the French to test their Élan once again and charge them. But while a Marshal like Bellegarde would surely do that and engage in a brutal battle of attrition until the enemy population was reduced to zero first, Mercer had a more innovative approach. Vienna wasn’t necessary, defeat the Austrians was, the city was put under siege, with the defenders locked around the city. The Siege of Vienna was a maneuver of the French to draw in the main Austrian force to relieve their capital and Emperor (that refused to leave the Palace), and it worked, with the old General Radetzky leading the relief force and ending the siege of Budapest. The Battle of Vienna would be the largest and bloodiest battle in the history of Europe until then, with both sides having the number of troops that not even the Romans had in their peak. While 70,000 defenders were trapped and surrounded near and inside the city, over 250,000 Austrians would come from the North, beating back 130,000 Frenchmen trapped in the opposite bank of the Danube (thanks for Austrian sabotage of French bridges). After 2 days, those French troops were surrounded ironically, and the French approached the Austrians with an offer to exchange the prisoners: Vienna for the French Northern Flank. Radetzky accepted, but as an Englishman once said: Never trust a Frenchman.
On the day of the prisoner exchange, Mercer’s French army crossed to the North of Vienna, meeting the Austrians and receiving their prisoners. But Mercer had set a trap on the Austrians, and as they marched north and the Austrian forces prepared to move south, to the other bank of the river, fire ships filled with explosives burned the bridges, and the French turned against the confused Austrians in a vicious attack. The Austrian forces didn’t have time to enter in formation and every man was left to fend for itself as the banks of the Danube turned red. Eventually Austrian morale was shattered and the people of Vienna watched as their army was destroyed by a dishonorable stab in the back. With no hope of a relief force, Vienna would surrender and Archduke Ferdinand taken as prisoner. Austria was the First Nation in the Coalition to fall, and now the French turned north to Berlin.
