This situation came up in a game recently.
My buddy is playing the Shadow, I am the Free Peoples. He attacks Osgiliath and hits nothing, I hit nothing. So he decides not to attack anymore.
I want to retreat my two Gondor regulars to Minas Tirith, but he says I can't because it appears as though the rules only allow the defender to retreat if the attacker decides to continue the battle. His strategy here is to force me to leave two regulars exposed for an easier kill, or force me to use an Army die to move them to the stronghold.
Clever, but is his interpretation of this correct?
Thanks
