Has anyone done a timeline where Fort Sumter holds until relieved in 1861? It can include earlier reinforcements, different armament, anything reasonable to make the fort reasonably ready for an assault from the land.
If not, what would be needed for the fort to hold? POD can be well ahead of the battle, so long as it doesn't massive butterflies elsewhere.
