Actions for province with a fortress...

[earwicker7]

This is a fairly simple question. If you control a province with a fortress, I know that you can keep the troops inside with the Defend command, and outside with the Patrol command.

My question is... where are the units which do commands other than these two? If a leader is preaching, will he be doing so outside the fortress? Same goes for researching, blood hunting, etc.. I could see a blood hunter being outside, but you'd think a researcher would be behind castle walls.

One other side question... what are the pros/cons of defending vs. patrolling if the attacker has a weaker force? Is it best to just patrol, and that way you take most of their force out when they attack, or are there any cases to be made for staying in the fortress (other than it being cold outside lol)?
