matteo,
I mostly agree with that.
I think the 'forced retreat' is you saying potayto, me saying patahto. The russians went with an unorthodox move because, as you say, they knew simply going toe to toe with France's armies was not a good strategy.
As you also say, it takes two to do the dance, and Nap stupidly played his part to russian perfection. I seem to recall Davout advocating a different plan of action, but Nap shot him down. I also recall that the Russian commander planning the retreat was under immense criticism, and that it was only Nap's willingness to play his part and lose his army that gave the Russians hope. If Nap had declined to play his role, the Russians would have been forced to come forth and go toe to toe, which they likely would have lost.
Nap was a great general, but he was saved in some of his battles by subordinates. In the end, he lost his luster and proved himself mortal. I don't know that this was the result of taking on too much as head of state and supreme military leader, a belief that he knew better than davout, whether physical ailments were clouding his judgement, whether he just wasn't as great as he thought, or a combination of all that.
I think we both agree that his actions in Russia were the wrong actions. Don't know that different actions would have been successful, but we do know that what he did do was wrong (hence his demise).
I do wonder if he could have held on til his OTL death. I don't think he could ever win, because his style of winning depended on total domination, and total domination on such a global scale is impossible, IMO. but, he could have stayed on top longer than he did.
Victory in an alternate war would depend on finances. Was France in 1812 fiscally sound? could they ride out the storm with their army in Poland? Could Russia pay for their army for a couple of years without a real battle victory? Did Britain have enough left in the coffers to prop up Russia? It would be interesting that one of Nap's biggest blunders (taking on Britain economically) may have been his one hope for victory blown because he decided to settle Russia militarily. Everybody at that time was fiscally and materially hurting. France was bled by Spain, but everyone was drained. An alternative to massive military victory in Russia would depend on a war of attrition both materially and financially. Could France last til 1821 financially? Could Britain?
