Lee's Failure to Invade the North

It was all around just kind of bad strategy, cocky strategy that came from over confidence because of all the victories. So he decided to sort of try and do a knockout blow invading the north. And things were different than any. Troops fight differently when they're on what they consider their home ground. If Ukraine really, well, now it's pretty clear Ukraine is not going to invade Russia because they can't even advance in Ukraine very well. But if they did, Russian troops might very well behave very differently.
