I am not sure Napoleon was ever really himself after the Russian campaign. What he expected after his victory at Borodino and what really turned out was very different. Expecting the Russians to surrender only having them chase him all the way back to France may have put some doubt in his mind. Maybe that doubt is what affected his decisions at a place like Waterloo. I know in sports that if you loose your confidence it can be hard to get back. I imagine the same could be said about war generals. Just a thought. Enjoyed the post.
Under the Bismarck sortie the BC Prince of Whales should have been finished off and the 2 ships together made way for Brest. Then waited for Tirpitz to come out along with Scharnhorst and Gneisenau (spelling). Those 4 BB would have been something to behold. The admiralty would have been in stiches. Most of her capital ships were on convoy escort in many locations and the Germans had the advantage of deciding to focus on a single point of there choosing.
