When Virginia pretended secession it meant nothing, as they had not the legal authority to break the union of all the states. When they made war against the US, they made their state government invalid, but did not removed the territory and people of the state from the union, as again, they had no authority to accomplish that. The state became a territory, and the Congress had authority to redraw the boundaries and to set up local government just as the Congress has authority to set up local governments in any US territory. Subsequent to that, the Congress admitted WV as a state, just as other states (like Vermont) had been accepted as states, despite failed claims by both NY and NH.
Glad I could help you with that.
That’s some imagination you have there. Have you considered writing novels of fantasy or alternative realities? You seem well-qualified. As between us, you may feel free to have the last word.
