This mission is very thick with enemies, so be aware of who has area effect powers and healing powers. Keep most powers on automatic (right-click to have the hero auto-activate), but keep Aragorn's healing power under your control. If you have the Heal power from the EvenStar, keep that recharged before moving into another encounter. Gandalf and Gimli both have area effect attacks, and Gimli's leap attack recharges quite quickly. Other critical powers are Boromir's horn and Frodo's Vial, both of which can buy you time because they essentially incapacitate a lot of the enemy.

The mission consists of various scripted events. When you are given a task, check to see if you can wait or not. The initial tasks to help Gimli and Legolas cannot wait, but both Gimli and Legolas do fine on their own, so there's no need to hurry.
The mission to save Boromir is optional and possible even on Hard Difficulty, but it is very hard if you do not have healing abilities ready. Also notice that Boromir is not added to your hero roster yet, so you can wait on this mission until your existing heroes are fully rested. As soon as you get close, Boromir is added and his health starts ticking down from attacks. Lurtz will probably have him pinned with his power, so you may have to spend one of your healing powers right away.
If a hero is in trouble, try to retreat them first if the others are still quite healthy. In general, keep your heroes fairly close so that you can get all of them with a single application of your healing power.
