The South were not mere rebels, they were secessionists with a large territory bigger than Spain and Portugal combined and with their own organised military. You talk of the Confederates as if they were some kind of Communist anti-colonial guerrilla.If the US had armies trained & equipped on the Continental scale prior to the Civil War then, provided the troops remain loyal to the Union, the rebellion is probably crushed in a matter of weeks.
