1) Do leaders count as part of the stacking limit for a space?
It clearly says terrain does not count, but I couldn't find any mention about leaders and stacking in the book.
2) In the deployment/setup phase, do you have to put exactly 4 cards per rear position, and 4 in your hand?
2a) How about in 1st St Albans, scenario 1, does Henry VI count as one of your 16 cards? Do you take 4 cards initially, then discard 1 to respect the modified 3-card limit?
3) For the flank spaces, is it 4 combat units per player per flank space?
4) Flank spaces can have units of both sides occupying simultaneously, and no combat is possible inside of flank spaces?
Thanks for your help! I played tonight with leaders not counting towards stack limit, but not sure if that was right.
2a) Henry should be set aside (not in a battle). Take the initial 16 cards and then discard one from your hand to account for Henry.
3) No. Unlimited.
