My larger point -- perhaps not clearly stated -- is that only in Virginia did it appear the CSA had a real chance to alter the Union's strategic goal, capture of Richmond and the bread basket of the Shenandoah.
Furthermore, this was the only theater where it appeared the South had a strategic goal at all! Washington DC was there and so it seemed the goal was to use Washington as bait to trap the AoP.
In terms of Union goals, Shenandoah was a perpetual back-and-forth affair. The Union did suceed in capturing the vital Hampton Roads area and securing one more potential Confederate port of call. In terms of the Anaconda Strategy, the Union had total mastery. Whether Savannah, Wilmington, Hampton Roads, New Orleans, Mobile, or Charleston the South lost nearly all access to the outside world.
If that war was truly about "state's rights" vice a smokescreen excuse allowing "polite society discussions," then the CSA would have freed all slaves, gave the Union one week to pull out of their garrison at Fort Sumpter, and then opened the war. England would have allied with the CSA and Lincoln denied the all-important moral argument of slavery would have been unable to muster years of sacrificial effort among the north necessary to win the war.
Alas, the CSA didn't do that. So, that pretty much seals the truth! And having surrendered all that, the Union had a strategic advantage making Confederate victory a very daunting prospect.
Hence, I'm very happy it turned out as it did.
Cheers,
