Then the retreaters get chased.How would you rule it if 2/4 members of the party are unconscious and the remaining two players decide it's time to retreat, and the enemy has reason to pursue them?
The question then becomes whether a) all the enemy chase the retreaters thus leaving the unconscious characters behind to - if they're lucky - recover on their own, or b) the enemy splits, leaving some to deal with the fallen characters while others chase the retreaters.
Beyond that it'd be entirely situational what happens next.
