im staring at the playbook now, it only tells you what corps are attached and what hex it is in, does not say how much SP is contained in an army to start
looking at scenario 2 the debacle
It is all there. The armies SPs are broken down by their individual corps. So the Prussian 1st Army has the VII Corps (5Sp), the VIII Corps (5Sp), I CD (2 CSp), etc.
