Einmal ist keinmal
You'll Never Walk Alone
Just picked up this game. Played my first a couple days ago.
If I have more than 5 army units in say, Minas Tirith, and the shadow player attacks it, can I retreat only 5 army units into the stronghold and leave the remainder to fight a field battle? Or do I have to retreat the entire army, sending any remaining units to the reinforcements box?
I'm afraid not. When retreating into the stronghold, any units above five are eliminated. (Remember that leaders and minions/characters do not count as units).
Edit: Here is the rules reference, p. 31:
Any unit in excess of five is removed immediately when a Stronghold comes under siege. Units removed in this way can re-enter the game later as reinforcements.
