What constitues a legal flank contact?
To count a legel contact on an enemy left flank, the attacker’s left front corner must contact the defenders left fron t corner, and the attacker’s front edge must be in contact with the defender’s flank. A right flank contact is the same, except that front right corners must touch. Note that this means that if the defending element recoils, it may still have the attackers front edge in contact with its flank, but this will not count as a legal flank contact. One or other element must move to resume the contact. There is a school of though that allows this as a legal contact, however.
