Help Me Take Down a Vastness

[Stryke11]

So I took them down, in the cheapest way possible. Every turn I would throw chaff sea troops at their seiging force and get turned back. I just did it to keep their conventional forces down. Well, I finally attack with about 200 mostly shamblers and tritons, and I took out everything, even their god, but not the vastnesses. I surrounded the vastnesses and they were just wailing on my guys, but they decided for whatever reason to run away, even though they clearly could have won the battle and my guys were at the breaking point.

Unfortunately for them, I owned all the surrounding provinces. So somehow they got lost and died, I guess.

And now I'm assaulting Pangaea on their island from the sea, Normandy style. Those uber minotaurs are pretty nasty. I think I may play them next...
