I have to admit, I'm surprised by how many people have told me I should have fudged it, or (even stranger, IMHO) retroactively changed my decision. Isn't one of the appeals of D&D that the ULTIMATE IMPARTIAL CRUELTY OF THE DICE should be superior above all else?!???!!
I know when I'm a player, I obviously don't like it when my PCs die, but at the same time, it kind of "weakens" the campaign when the DM breaks the rules to save people. Nothing is lamer than a DM who hits the players with too-tough opponents, and then has to backtrack ("Uh... the orcs don't attack this round because they're too busy laughing and gloating!") in order to save the PCs from dying or being captured. Then, as a PC, you feel like the DM is just gonna shelter you from harm....
Of course, it's still bad because the player wasn't there... sob....
And of course, this could lead to a much bigger discussion....
