just a little idea for the nobles, perhaps when you win a battle in whihc you are outnumberd, say 2:1 or more, and there is a noble nearby, it could increase their loyalty (they will start to see you as a "proper englishman" and a good leader too)
eg:

2:1 +1.5% loyalty
3:1 +2.5% loyalty
4:1 +3.5% loyalty
etc etc
