I usually tell my archers to hold fire, then I circle the enemy with my cavalry and harass them so they turn around to face me.
Then I order the archers to open fire in their backs while they are facing me. Doesn't do a LOT, but it takes down some of the lighter units.
And in my book every unit downed by an archer is a unit that didn't get to hit back.
For the most archers are best used for defending in sieges and for taking down archers that are defending in sieges.
Some castles allow archers to do some brutal damage to enemy blobs ie. Norwic.
Cavalry is for as far as I know really most useful for harassing the enemy which causes them to start advancing.
In my experience you are almost always better off using a defencive stance on the battlefield.
The enemy is usually stubborn enough to stick in their starting area until one of their units takes a hit and that's where cavalry comes in.
And even then they sometimes refuse to really advance unless you keep at it
Something else entirely;
Can anyone tell me how to grant a lord a fief if you have kept it unlorded so you could decide later?
Every kingdom report says that granting a certain fief has been on the agenda but it never says where to actually grant it...
I tried talking to the lords, visiting the fief itself and talking to my minister already.
Do I maybe need one of those companion ministers?
Yep, seems like you need a companion minister.
