About Burnside's difficulty in crossing the Rohrbach Bridge? Horrible thing is that Antietam Creek can be forded on foot. I've been there and it's not that deep. Then there's the ford a bit down river too. Must be feng-shui where Burnside had this thing about cross water or something. If anyone doubts that, look at Fredericksburg (I).
