I hate what just happened to me. I got a nice group of Swadian recruits, and trained them to Men at Arms. I then headed to Rivacheg to farm Sea Raiders. After I took on a few groups I now have: 7 Swadian Knights, 1 Swadian Man at Arms, and me (who counts for quite a few.

) I accidentally attacked a group of raiders close to another group, and so it is us 9 against 59 Sea Raiders.
Here is the deal - we killed 46 of them before I was knocked unconscious (I was careless) and did not lose a man. I figured, hey, might as well finish it. I didn't lost a man with 9 against 59, my 8 against 13 ought to go easy.
I was wrong! I lost 2 knights and the Man at Arms!

And I still did not take all the Sea Raiders out. In disgust, I left the rest of the miserable bandits. So yeah. I freaking hate the autoresolve function in this game.
