It's aaafter miiiidnight...
Okay, let me clarify a couple of things:
1. Isaac and Neri killed their zombies. Syana and Meera (the wolf) attacked and injured one zombie (who in turn hurt the bard pretty badly), while Volkmar hit his own zombie (twice). So it's not one unstoppable zombie, it's two that just haven't yet taken enough punishment to fall (curse the dice).
2. You have the two zombies still essentially in the road, both damaged. All eight of the new zombies are in the woods, having come up behind you guys from the same direction you originally came. Three of these are now in melee range, the remainder will be in range this coming round.
3. Shianna can indeed attaempt to turn the new arrivals. The basic rule of thumb is that you get one shot to turn any given undead. Since these were not addressed in your last try, you may certainly try again.
If you guys *do* want to break through and run for it, I need some specific questions answered. Neri has stated a willingness to stand and cover your retreat (yay lawful stupid!). What if one or more of you fall in the attempt? Syana is hurt badly enough to require medical attention, and soon. What if she goes down?
Please do note that if you turn and run while engaged in melee, your foe gets a free shot at your back.
