Well, I guess a battle plan description and brief account is in order to clarify the results I posted above.

1. Danish
Deployment : Double line with a thin, loose formation of spear militia in front (charge breakers), the axemen at the back, the shooters on flanks oblique, cavalry even further out. Looks someting like this :
- - \ =========== / - -
Account : I marched the army as quickly as I could towards the enemy, and just charged the axemen through the sparse spearline at whatever was in front of them. Cavalry moves to flanks and rear of the enemy. Archers & XBows : plan was to move them outwards and shoot along the line from both sides once the battle was joined. The xbows had not much of an impact though, as they got charged and killed quickly.

Feeling : Tense battle, any mistakes and it could've gone bad.

2. Milan
Deployment and account : similar to the above.
Differences : Solid spearline this time, with the DMAA in square blocks spaced behind. Xbows lasted somewhat longer being protected from the inital charge with a countercharge of my own heavy cav. They still didn't played the major role I remember them from campaign battles.

Feeling : Quite close. I actually thought I would lose this this one until almost the end.

NOTE : In both of the above battles you'll notice there's one cav unit that scored ~300 prisoners. That's the "router patrol", a unit sent behind the enemy whose sole purpose is to make sure the infantry units breaking from the main line don't rally and go back to fight. All along the battle line I tried to create local advantage by numerical superiority or threatening rear charges. This caused the foot knights to rout early (30-45 men), just to be ran down by the patrol. This tactic requires a lot of micro (50-60% of the time spent manually driving that one unit), as the router chasing doesn't work well on auto and the only way to be effective is to use the click-ahead trick.

3. Hungary
Deployment : Back at the map's edge. Double line, xbows front, knights & spears behind. Heavy cav on flanks. HA's in squares, one behind another, further out on flanks and ahead, close to the enemy. Like this :
Code:
h				               h
h				               h
h				               h
h				               h  

   B H       x     x     x        H  H
             == == == == ==
Account : Run the HAs to the sides of advancing enemy, shooting along their line and rear on FaW ; their heavy cav gives chase in vain. Used my heay cav to charge whatever DFK or XBow strayed too far from support. When the line joined, close all available cav (ie those not skirmishing away from HRE knights) from flanks and rear and mass charge then pull back, chase routers and charge again anything that's still standing. When the main line's gone, gang up on the knights.

Feeling : Almost too easy. HAs are the most powerful M2TW unit type.

4. France
Deployment : Three lines : heavy cav at the front, xbows middle and foot at the back, alternating spears with swords in line. Mounted sergeants and additional heavy cav out on flanks, facing inwards (sort of wide U shape).
Account : Heavy cav frontal charge, HRE xbows gone. Pull back a short distance then charge again, since the AI is slow to react and the dismounted knights line is still exposed. Pull the cav to the flanks, while the former flanking unit move to the rear of the advancing enemy. Let the xbows shoot whatever they can, then pull back. Engage the line, matching spearmen to cav and knights to spearmen. Rear charges, sandwich the HRE knights, mass rout, game over.

Feeling : Fun, intense cavalry battle, moderate difficulty. AI a bit dumb, moving xbows too far ahead an failing to push spearmen out to counter the charges.
