Sam Houston.
A man who served as President of one country and later ran for the presidency of another. The US.
Sam Houston was also very much against Texas joining the Confederacy. Smart guy, old Sam.
“Let me tell you what is coming. After the sacrifice of countless millions of treasure and hundreds of thousands of lives, you may win Southern independence if God be not against you, but I doubt it. I tell you that, while I believe with you in the doctrine of states rights, the North is determined to preserve this Union. They are not a fiery, impulsive people as you are, for they live in colder climates. But when they begin to move in a given direction, they move with the steady momentum and perseverance of a mighty avalanche; and what I fear is, they will overwhelm the South.”
Sam Houston, April 1861
