Simulation Strategy: Base of Supply Challenge

In a previous post, I noted the Federal advantage of having access to the B&O Railroad and a Confederate advantage is the rail lines are cut. Another strategic consideration is keeping a clear line of supply. Romney is the primary objective of the campaign with the most points awarded for control. It is in the south central part of the campaign theatre. The opposing bases of supply (Cumberland and Bloomery Gap) are in the northern corners of the theatre, connected by turnpikes and with a short-cut available that is a secondary road. Federals have rail access to Green Spring Depot, about half way to Bloomery Gap.

What will the Confederates do? How much resources will be used defending the supply line to Bloomery Gap and how much will be allocated to taking Romney and other objectives. Likewise, how many resources will the Federals allocated to guarding the railroad and preventing an enemy move against Cumberland?  Green Spring Depot, Okonoko and Lowell's Cross Roads could become a hot spots. Or may a move through Taylors Ford.... 

This is the difference between a campaign simulation and a tactical simulation. During a campaign, there are so many considerations that it becomes almost impossible to have all of your army together at the same place.
