Stealth Troops

[Falkor]

1. Stealth does not help by retreating. Troops will not sneak in nearby enemy provinces after loosing a battle. Best example is a scout being captured far away in enemy's land. If he's not been killed you get the message about him escaping into enemy's province and dying.

2. You can not attack your own province. You can only defend it.
No troops, commanders in Dominions can attack a province after loosing a battle in neighbouring province.
It can happen that you fight the same army twice in a turn. If you defeat your enemy in magic phase (teleporting etc.) you can still find some remnants of the same army in neighbouring provinces if you attack these provinces by normal moovement or by using stealthy troops hiding in the province. Stealth has nothing to do with it, though.
