Commanders Break Beserk Once Healed? (and) Flying Troops make Morale Checks?

[Immaculate]

I have wanted to know the answer to these two questions and searching the forums has produced contradictory answers:


1) Once a commander who has gone berserk heals the damage that caused him to go berserk (though regeneration for example), does he stop his berserker spree? If so, does this occur in all cases or only in the case of a strong nature bless?

2) If a flying unit is ordered to attack rear, what sort of checks does it need to make to actually reach the rear? Is it morale based?

2b) Same question for cavalry or other flanking units making an 'attack rear' attempt.
