This has so much potential. Cutting off supply lines causes troop starvation which drives up desertion. A poorly fed army vs a well fed army....
Obviously doesn't work in BM. Long campaigns are already difficult with EQ dmg and payment. If you are warring 3-4 regions from home, and someone 'cuts off supply lines' (what a romantic notion), you just turn around and fight them like you were already going to. It is just a meaningless concept. There is no front line in BM, only army balls.
