Iron Fist of Pelor
Given the setup, I kinda think it'd be fun to have a fifth column made up primarily of women who escaped the slaughter, and who are completely badass about it all. If you go with something like this, delay letting the PCs in on the gender of the fifth column until the last possible moment: these women will be very adept at hiding their sex and very wary about whom they let in on the secret. Until that point, they might be completely cloaked and masked whenever they're around the PCs.
Remember that different drow may work at cross-purposes to one another. Come up with some selfish motivations of different bad guys in your adventure, and clever PCs might find a way to drive a wedge between their enemies.
Is the ongoing war just vs. humans, or are the night elves engaged in another conflict? Consider opening a third front on the war at some point: either a demon invasion brought about by a foolish night-elf (or, better yet, human) wizard, or a rival drow clan, or an illithid move, or something like that.
Consider making the war ultimately winnable: maybe there's another human nation across the ocean that can be persuaded to join the war, and if they come over, they stand a good chance of crushing the drow. The PCs could travel there and have some diplomatic adventures; on the way, you'd have a chance for some nautical hijinks. Think resistance forces in Europe during WWII.
Emphasize cruelty: the PCs may find themselves hunted, and the drow might announce to the town in which the PCs hide that they'll burn one human alive every five minutes until the PCs surrender.
