1. Anderson decided on his own to occupy Ft. Sumter. Ft. Moultrie would not have been a menace.
2. Lincoln decided to re-supply the Ft. , when the soldiers would have been forced to leave due to lack of food.
3. As I mentioned earlier, the Confederate Government was left NO choice, but to reduce the fort, because of it’s position.
Oh hang it up, would you? Admit it, there was no legal justification for stealing the fort. They wanted it. They took it. they started a war over it. They lost the war they started. End of story.
No more legal reason than then US had by invading Cuba.
I will give up. (when I’m dead. :)
