Some questions from a Newbie

[kosmoface]

1.) How does the enigne decide who wins the fight? Sometimes I have big losses, but I'm also the winner. How so?

2.) Sometimes I win and my soldiers have to leave the region, as if they lost the battle. What are the rules for that?

3.) Okay, the turn period is 15 days. If a column enters a region on day 13 and it has to go one or more regions in the next turn, does the enigne add the 2 days or are they lost? Do the two extra days count in the next turn then? Or am I thinking to complicated?

4.) under the little buttons on the left (reight to the minimap). there's one where I can oder my soldiers to enter enemy structures (if they have a marching order). What do I gain from that?
