Here is the situation :

My two Assyrian BGs (A and B) have charged. BG A has conformed, but BG B cannot because it is in contact with two opposing BGs. When it gets to my opponents turn, he also cannot conform because BG Y cannot slide into full frontal contact.
My BG B fights (and would, if it could, conform to frontal contact with) the right file of enemy BG X and the left file of enemy BG Y, so the other two enemy files can both count as overlaps against it. If it could conform with the right file of enemy BG X, then I could expand a file from BG A into contact with the middle file of BG X. However, I am not able to do this because BG B does not conform so there is not room.
Is there nothing we should have done to enable the BGs to conform ?
Both my BGs were fighting at ++, but because BG B was double overlapped I lost it. (yes I know I could have expanded BG B to the right, but I lost a front rank base at impact, and enemy BG Y has more bases out of the picture, so expansion would have made things worse).
