Sorry if I misunderstood you.
I thought you were trying to say Georgians today could effectively resist a similar march by the US Army.
Which is of course nonsense on really high platform shoes.
I live in Georgia, in one of the towns along Sherman’s route.
What you say is true, but the US Army could only do ONE "march" at a time as it is miniscule compared to the US population. So while the Army was in say GA there would be 20 other states massing against them. Think about that.
