Entering a Marsh in this game is really dangerous you do it at your own risk. Therefore is not a good idea especially if you are retreating.
You have to roll to check your units.
So it is clear what happens when 1 unit (cavalry, infantry and leaders) enters the swamp (rolling the symbol implies loss of block/leader).
Less so when a Leader is attached to a unit. Rule at page 21 says:
If leader is attached to unit that loses a block, this loss does not require a leader casualty check but what happens if the unit doesn't lose a block? Do I have to roll for my Leader?
