And when they first reached the cave entrance, things looked promising. The druid spoke with a rabbit and convinced him to go into the cave and scout things out....
The rabbit runs in and several minutes later runs out - with some dolgrim behind him. The party sees the dolgrim and without waiting to talk to the rabbit about what he saw inside decided to charge them - so they did.
The whole time I felt really bad and just kept thinking, "It wasn't supposed to turn out this way. If they had talked to the rabbit, they would have figured that out."
Did the PCs actually have time to question the rabbit?
Perhaps I've misunderstood the situation, but it does not appear that they did from what you've said in your narrative. If Mr. Bunny's information was crucial to their success, I would probably have allowed the players to receive the information before the dolgrim came running out of the cave in pursuit. This also rewards the players for being clever; in the situation that played out here, you allowed their good idea (sending in Rabbit to scout) to blow up in their faces, thus further discouraging them from using stealth and subterfuge as a means of resolving problems.
It also seems that Mr. Bunny stirred up quite a hornets nest by venturing into the cave. I don't know much about dolgrim, but do they always get up in arms like that over small animals wandering into their lair? I can visualize one or two of them perhaps trying to catch Mr. Bunny as a tasty morsel, but sounding the alarm and raising the lair over one small rabbit seems a bit much.
You wanted a "sneaky, stealthy session", but it seems to me that the reasons it turned out otherwise were primarily the result of your own decisions as DM.
The players did the right thing sending in their little scout. I would have sent the rabbit scampering out of the cave entrance, running for its life, but I would also have allowed the characters to communicate, however briefly, with the rabbit before one or two dolgrim show up at the cave entrance in pursuit of the rabbit.
Even if the players' still charge the monsters, they will at least have received the rabbit's warning and can react appropriately as the fight unfolds and the rest of the lair becomes aware of their presence.
Hope that helps.
