Good point. Texas is still at war with the United States! Thanks for pointing that out.
My point was that any State Militia troops not in Confederate service (and there were such troops throughout the South, a lot of them in Texas from reading other sources about the Confederates' difficulty in obtaining Militia troops) would not have been stood down by Gen. Kirby Smith's order.
His writ ran only to Confederate troops.
Again, giving the contempt for constitutions prevalent in the confederacy, Texas may very well have considered herself to be at war on her own. But I think I can safely say that the rest of us are not losing any sleep worrying about the Texas hordes launching a summer offensive.
