Warband A and B must make spontaneous advances.
I decided to move A first.
It goes straight ahead and hits C,
then pivots to face the same diection as C and ends its move. It ends closer to the previously nearest enemy element X so it can't use the first bullet to contact X.
Then B advances. A straight ahead move would contact X, but in doing so B has moved in the narrow space between A and X, which is not sufficient for its frontage (depending on in which direction you measure it). THis is not permitted (top of page 32).
Therefore B moves straight ahead until it reaches the gap and then must stop. This ends closer to X so it can't use any of the bullets to do other stuff.
The net result of this is that neither A nor B could contact the enemy in front of them.
Is there anything open to interpretation which I could interpret differently to allow the elements to get into contact?
