Theres some guy with a big cresent moon,
"i cant build him only seen enemy's send him to get my land i had taken from them so i dunno what its called"
if he comes along he asks you to hand over the province peace fully,

And i usuly get help from an ally when im beseiged in my castle and moove a unit up to releve the seige without Takeing ppl out of the castle.

I will always March my troops to the aid of a besiged ally.

But i hadnt noticed that the larger army in a combined attack took the province,
