You've driven back the attackers, but some of them seized your bags during the fight and took them as they fled. Inside one of those bags is the gold that Saruman gave you for your quest, so you pursue the thieves deeper into Dunland.
When Revealed: Make Munuv Dûv Ravine the active location (returning any previous active location to the staging area). Each player discards each Item and each Mount attachment he controls. Each player chooses 1 ally he controls and discards each other ally he controls.
In your zeal to recover the gold, you have been led into an ambush.
When Revealed: Each player searches the encounter deck and discard pile for a Boar Clan enemy and puts it into play engaged with him. Shuffle the encounter deck. Each player shuffles his discard pile into his draw deck and draws 1 card.
Forced: At the end of the combat phase, advance to stage 3A.
