I have trawled through the manual and forum posts to no avail: I cannot get Army detachments to move. A box pops up listing all the Corps and asking whether I wish to make it an independent force. If I say yes or click on an Army the same thing happens again.
This happens when I try to move the German II Army - one part besieges Liege and the detachment just stands still back in Germany, ecven though I try to move it. I am sure I am doing something wrong but don't know what.
