Why do you think that only Alfstanna would have good archers?
Because it is not indicated anywhere else in the story. Unless a noble would bother with the training ( The English who were famed for their archers had weekly practices ) then a crossobw would be better.
If an opponent is armored then even WITH training an archer is weaker, much weaker in fact.
I've been thinking about terrain, and also about how slowly an army moves. I know high ground is good, but the opposing side would know what they were doing a long time before they got into position. Of course, they'd move just as slowly.
All ground can be given away if necesary. To focus on holding a patch of ground is to lose, to focus on destroying the enemy is to win. Using the forests to move your army is a very good strategy. or hell engaging the enemy with the majority of your army then sending a part to ambush them is sound strategy.
If the enemy is keen on defense, then pin him, encircle him and then wait for him to be forced to attack, then crush him
If the enemy is keen on attack, then draw him in a frontal assault and then flank him.
If he is both outwit him.
Of course, they'd move just as slowly. One thing I was wondering about was retreat. Suppose an army was losing. How do you retreat when you're toe to toe with the enemy and you have no fast moving vehicles or air support? If you turn and run, they'll just slaughter you. And where would you go? How would you get far enough away to regroup or excape to fight another day?
Rear Guard troops, usually reserve cavalry forces.
People will die during a retreat, but a good commanders always keeps some reserve units. Either for the purpose of frustrating the enemy while your force is retreating or to hunt the enemy down while they retreat.
It is always a good idea to always let the enemy have some way of escape, if not then well...he will fight like a cornered animal.
