The Yorkist battles each have 6 standard units. The Lancastrian battles each have 8 standard units. The battles must be deployed in the areas described above, but the units may be re-deployed within those areas & both sides are allowed to transfer up to 2 units from any battle to another while deploying. The Yorkists also have 3 small crossbow units & 2 medium cannon which can be attached to any battle but don't affect break tests.
Movement in the boggy ground in front of the Yorkist centre, the woods, the cornfields & on the scrubby hill on the Lancastrian left is 3" per move for all except open order bows or crossbows.
Shooting at cover is -1 to hit.
Shooting at buildings & barricades is -1 to hit plus -1 save.
Attacks on buildings are infantry only, no charge bonus, no supports (for either side), 5 dice per unit regardless of arms (3 if small), defenders save 4+, defenders ignore fall back result.
Attacks up the Yorkist ridges lose charge bonus.
Attacks on hedgerows, barricades & woods are no charge bonus, all troops 5 dice (3 if small), defenders ignore fall back results.
Lancastrians get 1st turn. Command is 8 for all, but our barbarian rule applies unless in road column (that is 9 to charge full steam ahead, 7 otherwise).
