Hi again,
Please look at the diagram attached. Elements A, B, C and D are mounted. A and B are looking leftwards, C and D are a column looking down. Elements 1 and 2 are enemy foot. Element 2 has contacted the flank of A so it must line up. By doing so, element C must be shifted the minimum necessary to allow it, but then 2 will enter the TZ of element D. Is the flank attack cancelled then?
Thank you.
