So, I was wondering what the effect be of Napoleon dying early into his campaign in Russia?
I chose Vilnius at random, but it was convenient enough.
So Napoleon dies right at the very end of June, 1812.
The manner of Napoleon's death isn't too important. His horse slips a shoe, he takes a tumble down some stairs, whatever it is, Napoleon or someone near him accidentally gets him killed.
How does his Empire hold together? Does it? Who is in control?
What is Britain's reaction?
How does that affect their foreign policy in Europe and in the Americas (the USA just declared war on them)
What about Austria's? Marie Louise is Empress of the French and Napoleon II has been born.
