Laughable. Shows a clear misunderstanding of Virginians, Washington the man, and history. The thought of FedGov going to war to keep Virginia IN the USA would have been laughed at.
No. It shows that you are so romantically attached to the insurrection that you have lost objectivity.
Significant parts of Virginia were opposed to the insurrection, to include what is now West Virginia, and the region near Arlington. Fitzhugh Lee said he would fortify Arlington with the guns pointed south.
Again, Thomas, Scott, and many other Virginians disagreed with the pretended secession, as did Lee, but Lee also was strongly attached to the institution of slavery and the privileges it gave him.
I will point out that old Virginia provided the 1st, 2nd, 3rd, 4th, 5th, 6th, and 7th Cavalry, as well as the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, 14th, 15th, 16th, and 17th Regiments of Infantry to the Union, as units from West Virginia, all fighting to put down the insurrection. Virginia never left the Union, and could not by the means pretended.
