I also have a question about stopping at least a 1/3 foot move from an enemy. If I'm moving infantry a short distance in column and I stop 1/3 foot move from an enemy, and I still have at least 1/3 of a normal (non-column) move left, can I then approach and engage the enemy in normal formation? (I assume yes, I just couldn't keep moving toward that enemy in column)
Does cavalry also get a 3x movement bonus if moving on a road in column?
(I assume yes)
I would think Yes to both questions. Units can really fly across the map in the PB system if unimpeded.
