I wanted to give you folks a chance to step in. We're three or so rounds into battle. The main party is making very slow progress in the tactical withdrawal, as the foes refuse to break engagement. The turning of the undead resulted in nine(!) zombies being removed from the fight, but you are still badly outnumbered. I have thus far resisted the urge to have a rapeghoul paralyze Ch'dau and end the satellite party, though I am unsure where I have found the willpower to do so.
Note that slow moving as they are, the zombies are beginning to overtake you with your "fighting retreat" tactic - it's not a line versus a line any longer, it's a longer line beginning to wrap around the flanks of a shorter one.
Health:
Ch'dau - light wound
Aranwen - moderate wounds
Gib - light wound
Kithran - moderate wounds
Midge - moderate wound
Cedric - moderate wounds
Magic:
Midge has six mana points remianing.
Cedric is down one 1st level spells and one bonus light spell.
