Walkthrough for the "Tribes of the East" expansion.

Has anyone completed the second mission for the Orcs on "Hero" difficulty? I'm just curious – is it even possible? =)
I've restarted twice, and every time, around week six, a turquoise player shows up with 12 Cyclops and a corresponding number of lower-level troops... Eventually, I gave up and switched to "Hard" =)

Of course, I've completed it. I always play on the maximum difficulty; the others aren't interesting. :)
By the way, this mission is quite challenging at the beginning. I myself only passed it on the third try. I had more problems with the brown player than with the turquoise one.
I spent the first two weeks not capturing the first castle, so the yellow player would build it, because I didn't have enough resources. Then, I took it when it was almost fully built. When the brown player arrived with a large army, I destroyed his catapult with my archers, and all his ground troops couldn't reach me anymore. Also, in the first battle with the turquoise player).
