Was I grossly unfair here? What does everyone think?
I am much more interested in "what you thought"?
What was your expected "good" resolution for this scenario when you designed it up?
Did you expect the PCs to be able to fight off or beat the assassins? if so, what did you expect them to do it with that they ignored? You mentioned them being frustrated by the enemy invisibility, so how did you expect them to counter that when you chose the adversaries? Or did you build this to be an encounter they would not beat and would have to sue for peace to get out of?
Now, assuming you meant for this to go to negotiation as it did, did you expect the everyone to agree to the back off, even the paladin? if so, why do you think he surprised you and would not go along? Was this decision "out of character" and surprising or what?
Also, you seem to think the ranger tracking the bad guys was not a good idea. It certainly doesn't sound like a good idea
as you presented it but moving beyond that, why do you think the ranger (player) thought it was a good idea? Was it an intentional suicide or did he have a wholly different expectation somehow of how that would turn out? if so, why did he have that expectation?
basically, can you look at
what you had expected the results of this encounter to be when you put together the challenge and designed the foes and circumstances, compare them to
how it turned out and comment on what was different between those two and why it was different?
EDIT: Read more of the thread and saw where you said
For the record, I expected the party to be beaten by this group in this setting - surprised, at night, in a well-coordinated ambush
So that answers part of it.
So, how did you expect this to turn out, with the party getting beaten as the expected tactical event... knowing you had a paladin, knowing the ranger's past performaces?
Has the party shown in the past a penchent for smartly backing down when overmatched?
has the paladin previously been willing to abandon quests?
has the ranger in the past been frequently heading off to track and stealkth enemies? has he typically been successful or failing at this?
Basically, we know you built the scenario for the party to lose the fighting part, but what were your expectations for how it would then resolve, how did the actual play vary from those expectations, and why do you think your expectations were so far off, if indeed they were?
