I (Castille) have 31000 men in my army (20 regiments of infantry and 11 of cavalry). Computer (Aragon) has 21000. During the battle I can see how much damage each one is producing. Every attack from them damages me 300 to 500. I only damage them 7 to 15.
Why is this happening? My men have high morale. I'm in my own territory. By the end of many battles I went from 31000 to 15000 and they only lost 3000 men and even regained their forces faster than me.
So pretty much I want to understand what I'm doing wrong and what exactly do I need to do to have a successful army. Also if someone can give me some pointers on the game overall.
