Is there an *1812, and when in relation to the European war?
Instead of going for Moscow, Napoleon stations his armies in Smolensk and Vilna, extending the campaign but building up the supply lines and logistics do Duchy of Warsaw.
Forcing Russian attack, the Grand Army manages to deal several blows to Russians, which lead to peace in 1813, the terms of which are quite easy on the Tsar. In terms of territory only parts of Lithuania are lost.
During the campaign Napoleon starts to realise that his battle genius is no longer the same as it was, and that enforcing peace by military means alone will not be sufficient.
As a result in the years 1813-1816 he tries to build up political position of France versus other powers, in part using his connections to France.
England continues to scheme against France and builds up another great coalition made of Austria, Prussia and Russian Empire.
Unknown to them Austrians have betrayed them, and when the war starts, Austria switches sides(it also gave information about war plans to France), moving against Prussia and Russian Empire. Metternicht is imprisoned for plotting against interests of Austria.
The resulting war ends with defeat of Prussia by which is turned into a depedency of Austria, and Silesia annexed back into Austrian holdings.
In North Sweden is convinced to join French side and together with French troops manages to take Petersburg, while Austrians, French and Poles manage to throw back Russian invasion.
In the aftermath Napoleon does arrange a Congress of Paris where European matters are resolved finally.
Sweden takes back its Baltic holdings, with Russia having only Petersburg as its sea outlet. Poland is restored with borders based on its pre-second partition with Louis-Nicolas Davout as its king. Additionaly an Cossack Hetmanate is made with its armies directly under command of French Emperor.
Out of Confederation of the Rhine the Kingdom of the Rhine is formed, with the exclusion of Saxony, that remains a seperate state and whose rulers gain Free City of Danzig as dependency(part of the city taxes go the Saxon court-compensation for losing Polish throne).
The system of French alliances looks like this-Kingdom of the Rhine, Kingdom of Poland, Sweden and Cossack Hetmanate.
The Congress is largely acceptence of Napoleon that France is leading but not the ruling country in Europe as the second power is Austria which gains Silesia and Prussia as dependency(reduced to territory of Brandenburg, Pomerania, and East Prussia with parts of West remaining).
During the Congress a truce agreement is made with England as well.
I know it's sketchy but those are the ideas I have so far.
Obviously I know little about French dealings with Spain, Italian states and I am not sure how to formulate the truce with England.
As for Latin America I want something like FRCA to exist as one of the migration destinations of Prussians in XIX century who are dissatisfied with Austrian rule over their country(doesn't have to be republic but a larger Central American state).
