Shelter Island Heights
The rule says a defender must retreat (if possible) in a friendly space.
Does this mean the defender can retreat in an ennemy space if there is no friendly spaces? Or the defender can't retreat and is eliminated if there isn't any friendly spaces?
The former. It just sets a priority, friendly space over enemy space. Not enemy space does not mean enemy-occupied, but enemy-controlled. It is not possible to retreat into an enemy-controlled space.
I have a comment about the set up: Richmond is empty at start and Mc Dowel can take Richmond via the Potomack river after garissoning Fredericksburg on the first turn if the player has a card to size the confederate initiative. Any comments?
At first blush, I think that's a possibility, but the CSA would still have the option and better chance to intercept.
At last how can I deploy Lee as the east theater commander in reinforcement phase of the third turn if J.Johnson is the theater commander? In the rules, I understand I can't demote a commander in this phase and I can't deploy a commander in place of one I transfer, but I'm not sure.
Well, I don't think you can in the reinforcement phase, but if there's an opportunity to remove Johnston during the campaign phase (defeat in battle, clash of egos, shot from the saddle), you might want to seize the opportunity.
I like this game.
