General's Morale and other Bonus

[Maltz]

There are two kinds of General's morale bonus:

(1) Personality Trait
(2) Retainers

Question 1: Are they always applied to all units wherever they are, or do they only apply to units that come within the daimyo's blue influence radius? If it is the former, what kind of bonus does a unit receive when it enters the general's blue circle?

Question 2: If there is a general leading reinforcement, does the reinforcement army gets their own general's bonus (morale, attack, accuracy, etc.)? Or does the reinforcement army gets the main army leader's bonus? Or any gerneal' bonus if they enter the general's blue circle? Or both general's bonus at all times?

Thanks.
