How is movement determined?

[carlosib]

There's one scenario that hasnt been mentioned. What if an enemy army is sieging one of my fortresses? According to the map that province is neither mine nor his...it has both flags. It happened to me in a MP game and i expected that since moving to a friendly province happens earlier than moving to an enemy prov at turn resolution i would catch his army. After all, if that province (the one with the fortress) had both flags, it should be taken as friendly for both of us, right? Well it doesnt...he still moved before me, taking another of my provinces...and kept running...
I assume that provinces with both flags arent friendly for any of us then. But i think giving the "friendly" status for both nations would be a nice way to make fortresses more useful while defending, isnt it? I mean, raiding a fortified province would mean that you have a chance to get caught by a defending army coming for you, and should be taken in consideration both as a defensive as well as an offensive strategy.
Anyway, just a thought

I'm pretty sure the besieger is considered the province owner, so the province is friendly for him. Which makes sense. He gets the income, can patrol, etc. He owns everything in the province except the fortress, so an army moving into the province is treated as if it was his.

Mostly correct, thejeff. He owns everything in the province except the fortress, lab, and temple.

My experience lines up with theJeffs. Though...
IME - Assassinations happen before movement.

I'm not certain what happens when the defending army trys to break siege and the attacking army tries to pull back to friendly territory. My guess is the siege breakers attack before movement since they're already there.

What happens when a scout belonging to player Y attacks the province A belonging to player Z he's in and the defending army belonging to player Z moves from province B to Province A?

Assassinations do happen first. Catching sneaking troops happen after other battles.

Siege breaking happens along with movement, since reinforcements for either side can arrive before the battle. The besieger pulling out to friendly territory happens first. Invading a different province should work normally.

I'd assume stealthy units attacking don't interfere with movement. In your example the defending army would move first, since it's friendly movement, then the scout would attack. I've seen this happen, using scouts to take 0PD provinces from the AI.
