In my PBEMs as the Union, Missouri starts off with strong union control in much of the state. But by late 1861-early 1862, most of the state suddenly changes from blue to gray control. I assume this change is driven by event as typically, the confederates are on the defensive (outside of raids) and certainly haven't conquered the state.
In my games, I haven't used martial law or police control because the state was under blue control and I saw no reason to lose the VPs for St Louis and Fort Leavenworth. However now that the state has suddenly converted to gray control (by event??), I believe it is too late to effectively implement martial law as you must have 51 percent military control to use martial law.
So issue number one-How to maintain military control of Missouri? Is it absolutely essential for the Union to implement martial law or police control from the very beginning of the game? If rebel military control is driven by event, will martial law or police control override any event driven changes in military control?
If you have already lost military control of Missouri regions, it is too late to implement martial law/habeas corpus. So how do you regain military control of the state? I am guessing the only solution is to conquer all cities in the state and heavily garrison all cities and all railroad lines.
So any thoughts on maintaining military control of Missouri??
