You know as well as I do that Davis ordered Beauregard to reduce the fort prior to the arrival of the resupply ships.
It would not have made a difference whether there were warships escorting them or not. Davis was not going to allow Sumter to be resupplied under any circumstance.
He knew it would probably lead to war. But he was not going to allow the continued occupation of Sumter by U.S. forces.
Right, and this is typically the point where DiogenesLamp claims that he can't respond because you're answers are "too long" or "just talking points", etc.
In fact even before Lincoln took office, Davis ordered Beauregard to prepare to assault Fort Sumter.
