Actually, I have to disagree with this. To my knowledge, all of the
details of target selection have never been publicly posted. (Not that
they are all that complicated, but....)
The rules as I understand them:
(1) All fighting men or beasts belonging to characters in the front

(2) A character in the front row is a target only once all of the
fighting men or beasts belonging to that character have been
(3) The stack leader is a target only once everyone else in the stack
has been taken out of the battle (killed or wounded).
