I think the Union have screwed up (and by the Union, I'm referring to me). I thought a dismounted cavalry unit and a horse artillery unit were enough to use as a blocking force. It wasn't and now the centre has opened up.
If the Confederates get the victory location on Telegraph Road, they'll have 2 victory locations on the first day and win...if they can hold them until 17:00 (it's currently 14:00) which is entirely another matter
I really, really love this game...but combat can get very, very messy and confusing
