~ Chapter 26: The Fifth Coalition ~
Austrian troops mobilised with a good amount of enthusiasm as the Empire prepared for a new round against the French. Even with the successful reforms of Archduke Charles there was no guarantee of winning, even if the French were very busy in Spain. Napoleon was aware that war was coming, however the real magnitude of the conflict evaded his thoughts. The reality was that Austria, Prussia, Russia and Britain were preparing simultaneous offensives against France to bring the empire down. France had already fought against similar coalitions and came out on top, and this time France started with a vantage point compared to the Third or Fourth Coalitions, as France had a secure control over Germany, an ally in the Duchy of Warsaw, and a Prussia that was militarily occupied by a force of some 10,000 men, garrisoning the towns of Glogau, Küstrin, Stettin and the Spandau fortress of Berlin. In all honesty, King Frederick William III of Prussia was not supportive of the plan, and most of the actual negotiations and planning was carried out by his wife Louise and a clique of men such as vom Stein, von Hardenberg, Gneisenau or Scharnhorst [1].
The Prussian reformers created a system of reserve forces dubbed the Landwehr, which by employing reserve troops only for part of the year managed to train a larger force than that imposed by the limitations of the Treaty of Tilsit (42.000 men, just 2,000 men larger than the French occupation force). Out of the 143 generals the Prussian Army had when the War of the Fourth Coalition started, said number was reduced to only three, with the entire officers corps being depurated and granting the middle class access to higher ranks in the army, thus breaking the monopoly the nobility had on the matter. Von Scharnhorst created a Ministry of War to better manage the military on Christmas Day 1808, replacing the older military institutions that often overlapped each other, and he also opened a War Academy, albeit this one would not open before Prussia joined the war.
The Prussian intelligentsia was also very busy in the months before the War of the Fifth Coalition. The writings of philosopher Johann Gottlieb Fichte promoted the ideas of a German idealism and nation, defending the idea that Germany needed to be reborn with the ideas of patriotism and the mythification of the Germanic past. The ideas of previous thinkers such as Immanuel Kant spread further thanks to Fichte, and it extended to many in the Prussian upper spheres, which led to the creation of secret webs and societies hoping to initiate a new era of German glory, such as the League of Virtue or Tugendbund [2]. These ideas were not effective in mobilising the peasants for war and would ultimately fail in their primary objective [3], but would prove to be an useful asset in the war.

The War of the Fifth Coalition officially started when the Austrian Army under Archduke Charles crossed the Inn River into Bavaria on April 10. The forces of Jean-Baptiste Broussier [4] pulled an ordained retreat as bad weather hampered the Austrian advance, stopping at a defensive line near Ingolstadt. The Austrian offensive, however, was defeated by the French at multiple battles, such as those of Abensberg, Ratisbon or Teugen-Hausen, with the Austrian Landwehr retreating across the border with Napoleon himself in pursuit. It was not after the Battle of Ratisbon, when he was recovering from an artillery shot landing near him and hurting his ankle, that Napoleon received news of the Prussian uprising and Russia’s refusal to aid him. Napoleon considered that the best course of action was to continue the campaign in Austria and ignore the myriad of rebellions that rose up all across the French dominions, and Masséna’s bloody assault at Ebelsberg on May 3 1809 opened the gates to Vienna.
When Austria invaded Bavaria, the kingdom called for a mobilisation of its population in all of its territories, which had been greatly expanded by becoming a French ally. One of those possessions was Tyrol, which had been obtained in 1805, and was not happy at all with its new status as three Bavarian districts. When a group of young boys fled Axams to avoid conscription, a general uprising began commanded by Andreas Hofer that rapidly dispatched the Bavarians sent to suppress them at the Battle of Sterzing, and then set up a trap which the hard-drinking French general Bisson set up and resulted in the capture of over 2,000 Frenchmen and copious amounts of equipment, as well as an imperial eagle, an affront to French pride. In early May Napoleon sent general Broussier to Tyrol, where he relieved the Bavarian garrison trapped at the Kufstein Fortress, but was soundly defeated at the Battle of Rattenberg on May 14, failing to capture Innsbruck [5].
Stories of the success of the Tyrolean militias spread like wildfire all across Napoleonic Europe. In Italy, when the Austrians under Archduke John launched an invasion across the Alps after scoring a victory at the Battle of Sacile, with Napoleon’s stepson Eugène de Beauharnais retreating behind the Adige river fearing to be attacked by Austrian forces coming from the Tyrol. The Austrians rallied the Venetians to their cause and a general mutiny in Venice destroyed taxation and conscription records and laying siege to Ferrara, however the Austrian Army was unable to keep up with their promise of help as Archduke John retreated most of his forces across the Alps to protect Vienna, followed by Stoichewich’s Dalmatian Army.
In Germany, former Prussian officer Friedrich von Katte launched an uprising at the town of Stendal on April 2, which succeeded in taking over the town of Magdeburg five days later from Michaud’s surprised French garrison [6], securing a crossing of the Elbe river for the upcoming Prussians under Ferdinand von Schill, who had departed Berlin earlier, and defeated the Franco-Westphalian forces at Sülzetal on April 12, with a good chunk of the Westphalian troops deserting to the Prussian Army. By late April, the French garrisons in the Prussian fortresses had either been overwhelmed or had capitulated, which allowed the core of the Prussian Army to attack French-allied Saxony in May, defeating the Saxon forces at the Battle of Herzberg on May 27 and pushing towards Leipzig. At the same time, Frederick William, Duke of Brunswick, raised the flag of rebellion and joined forces with the Austrians, causing a general chaos in the eastern part of the Confederation of the Rhine. In Poland, the Austro-Prussian forces launched simultaneous offensives, which the Poles managed to grind to a halt, however when Russia officially joined the War of the Fifth Coalition on May 24 the Polish Army was pushed into a desperate situation, which only grew worse when the (theoretical) Duke of Warsaw, Frederick Augustus, who was also King of Saxony, switched sides as Austrian forces took Dresden on June 8 and the Prussians captured Leipzig.

By late May, however, Napoleon’s army was very close to Vienna, albeit he still needed to cross the Danube River. He chose to do so at the island of Lobau, distributing his forces between the towns of Aspern and Essling, managing to bring 40,000 troops to the Marchfeld, crossing the river uninterrupted as Archduke Charles wanted the French to cross in order to trap them in the left bank of the river. Fighting broke out on May 21, and despite the increasing danger of crossing the unstable bridges the French kept advancing and launched fierce attacks on the Austrian forces even after the main bridges shattered. The Austrians then launched a counterattack and quickly took over Aspern, with the battle for Essling extending all throughout May 22, resulting in an Austrian victory and having Jean Lannes, one of Napoleon’s personal friends, mortally wounded on the leg as he was struck with an artillery round. The Battle of Aspern-Essling was a victory for the Austrians, and the first time a large Napoleonic force had been defeated in open battle outside of Spain.
However, the victory was so unexpected that the Austrian Army did not capitalize on the situation and allowed the French to regroup on the other bank of the river. During the six weeks it took Bonaparte to reassemble his forces, the Prussians were advancing through Westphalia and a Russian contingent of 30,000 men under Peter Wittgenstein arrived to reinforce the Austrians. The fate of Austria would be decided when 150,000 [7] Frenchmen crossed the Danube and headed towards the Coalition Army of 170,000 men.

[1] - Frederick William was extremely shy and indecisive, barely taking part during the Treaties of Tilsit, and it was usually the duty of Queen Louise to control the matters of the state, especially when it came to taking decisions.
[2] - Minister vom Stein was staunchly opposed to these secret societies as he considered them to be too radical, however he did not take action against them as they were a useful asset against the French.
[3] - Major spoiler here, if you can read between lines.
[4] - Lefebvre IOTL. Lefebrve himself is replacing Claude Victor in Spain as he was dismissed from command and is now commanding a cavalry regiment in Westphalia.
[5] - IOTL this force was commanded by Lefebvre and defeated the Tyroleans at Wörgl a day before TTL’s Rattenberg.
[6] - IOTL the uprising failed as the French captured Eugen von Hirschfeld, one of Katte’s collaborators and he disbanded his forces on the night of April 5 without trying to take Magdeburg.
[7] - 188,000 men IOTL, French units are busy elsewhere.
