Keep 2 DPS characters in the Base
Their Job is to destroy all the portals that pop up.
Dont worry so much about what comes out of the portals, just kill the portals and get outside as fast as possible.

The 4 characters outside must focus on killing the Catapults.
Healers keep all of the little soldiers alive.
If you are unable to kill the Catapults and they close in on the base.  Have the assassins windwalk and take them out 1 by 1.

If both bosses get to the base at the same time, have a tank taunt 1 of them and lure him into one of the castle wings.
The boss will get stuck there and you can focus on killing the other one without problems.

Useful tip.  All of the troops you buy, place them into the Dwarf King's throne room.
