Just clarification here:
When South Carlina seceded in December of 1860, all (previously) federal properties within her borders returned to the State.
Fort Sumter was OUR property, NOT federal property. It was within OUR territorial waters according to all international law.
For the tyrant Lincoln to reject Confederate peace emmissaries, then notify them that he would reinforce the troops was an act of war.
We drove the invaders out.
The tyrant Lincoln wanted a war, and he got a war.
Based on what rule of law?
