What was Napoleons "plan B" in Austerlitz?
Of course this battle is very famous for everything going essentially exactly according to his plan. He forsaw that, because tsar Alexander and others were prideful and desperately wanted glory, they would try to take advantage of napoleons inferiority in numbers by charging when his line appeared weak, abandoning the pratzen heights. But what if, in another timeline, Tsar Alexander and the austrians were a lot more forward thinking, or levelheaded generals held more control over the field and DIDNT abandon the heights? I assume Napoleon would have had a plan B to defend himself and his shaky supplylines with his inferior numbers, if the enemy didnt catch the bait? Or is his whole career based on "not interrupting his enemies while they make mistakes"?
