Europe seemed so big when I studied European History. All of the fraught war and diplomacy of 500 years fits into Texas. It's hard, even now, to imagine European reaction to something fought on the scale of the American Civil War. I don't think 99% of them had any idea. When you wonder where our railroads came from back at the beginning, a lot of them grew out of the logistic demands of armies that moved like locusts from Maine in the north to the Mississippi and to Florida in the south.
