As we don't see informations about, we consider that evading units follow the same rules as fleeing units when they have friends on their path.
So going around if larger or tempting to pass through unit otherwise with the risk of not crossing the unit and so remaining in front of it.
From the previous point we make interpretation that unit flowing around are after at the unit's rear, even if they have insufficient move, is this correct ?
Other question, what happened if there are several units in a column, does the unit finish at the rear of the last unit of the column ?
If a unit goes around an other one, its attacker have a mandatory contact to the second if it is less than half charge distance, he can't go around as the fleing or evading unit, or is there a difference between charging and pursuing ?
