For both to hit in the same turn, assuming the defenders move forward in Round 1, I think attacking infantry would need to be set up on the front row and attacking cavalry on the middle row, but there doesn't seem to be a marshal setting for that. Am I missing something?
Sometimes the best options not to use any marshal settings whatsoever it certain situations, but instead rely on experience and use custom battle lines etc, as even while have all the marshal commands myself I still find that works best in many situations.
