Someone posted Antietam/Sharpsburg in response to another comment about Lee's invasion of the North being Gettysburg, as if those two battles were a northern invasion.
I stated that since much of MD favored the south, those two battles weren't actually an invasion of the North, since they were fought in an area with plenty of CSA sympathzers. So, what was incorrect? Lee's expectation of picking up more troops in MD, has never been documented, that I know of?
