Especially since we have only one clear leader (and that's only because he's the only with a famous dynastic name), I was thinking we should simply randomly allot the crusader numbers among the characters participating in the battle.
I feel this is the most currently fair way to hand out power.
*I will not enter characters that have not been RP'd yet, however.

Let me know if you want out or in.
NB: Soldiers a character leads here are not necessarily their own troops; they are simply crusaders that chose to follow that character for the crusade, or were ordered to follow that character. However, depending on RP and effort, the soldiers may become loyal followers.
