Walkthrough tips, Discussion of Campaigns [Heroes 5]

My patrol units were constantly running around. I gathered almost everything I could on the surface, entered the Fortress, upgraded my units, and went into the Dungeon. Then, one of the orange players also went down there and captured the Castle while I was exploring the Dungeon. I defeated him there.

I don't remember this mission very well because I completed it quickly on my first attempt. But I remember the second one well, and even better – the third.
