Here's how I finally managed to pull this one off: ride the warsteed into the middle of the orcs as they are coming at you, away from the 2 helper npcs. Use the horse heal whenever it is off cooldown, and alternate the 2 aoe attacks as much as possible. The idea is to kill as many orcs as possible as quickly as possible. By the time I got knocked off the horse, there were only 2 orcs left. I killed them, and then I fought the trolls until my morale started to get low. Then I kited the trolls in circles around the helper npcs, and let them do the killing and healing.
I do not love the bright sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only that which they defend. ~ Faramir
