Also, if the allies retake the west hex of Dinant does that prevent the Germans from building further pontoon bridges until the Germans can regain the town?
I am not sure. The (original) French doesn't make it certain for me either. I think you have to keep the hex occupied to build bridges, but that could be wrong. You could contact jdrommel and ask, I've done so in the past for other scenarios he designed if something was unclear to me.
