Wow, this is a very challenging mission! And, as always, it offers a lot of experience. Although I only reached level 8 in the previous mission, I achieved a record-high level 17 in this one. Maybe even Tiangbo will reach that level :). And the main secret of this mission, which I realized too late, is this: don't rush after capturing the Wolf Fortress! Don't go to the second town; instead, first build up the first town as much as possible and clear the surrounding area. Then, more reinforcements will gather in that town ;).
