And now after reading the IC i just want to say, with no intent to offend either player of DM, but I think you are severely overestimating the abilities of our characters. That, or you are making enemies way too strong. Having the Mage and the archers die was nice but it seems like Carver can't land a single hit while you are hitting him, or hindering him, every turn. 

And with the party again split and reinforcements on the way it seems like we are again given the choice of flee or die.
