So, for those that missed it:
It began raining, which was a rather rare event from what we had seen. The villagers woke us up and informed us that the creatures didn't attack during the rain, and so this would be the perfect time to move the village to that tower.
So about three hours in, I believe, it slows to a drizzle and all hell breaks loose. A slaughtervine, feedervine, and two thorn hurlers (something we hadn't seen before, does exactly what it says) attacked our particular group, with a bunch of others attacking the rest of the caravan (mostly abstracted).
So we manage to dispose of the vines, with a lot of failed rolls, Frost nearly dying, and Inmontani both nearly dying and getting a javelin crit kill. Shivex nearly died also, but Inmontani was going right after him so it didn't count.
One of the few times Shivex actually hit with his mark AoO also happened to be bringing down the slaughtervine, which as you may recall is both elite and can shift a total of four squares during its attack, making it a pain in the ass to stop it from eating people.
Afterwards, Shivex and Ramum ran off to help another pack of guards, then returned and everyone rested. Ramum achieved his goal of not taking any (on-screen) damage during the fight, but Tarn had been critically injured and so valiantly perished off-screen.
After our five minute break, there's still sporadic fighting, with a number of the thorn hurlers keeping the caravan pinned. Alas, we've not had time to loot.
