Again, if Lincoln sent an unarmed, unescorted supply ship to provision Sumter, Davis would have ordered Beauregard to reduce the fort before the resupply effort could be accomplished. He could not allow the status quo to continue.
You are repeating that like a mantra. It clearly isn't true based upon the actual records. Since you won't look it up yourself, I'll find it for you.
Montgomery, April 11. To Gen. Beauregard, Charleston:We do not desire needlessly to bombard Fort Sumter if Major Anderson will state the time at which as indicated by him he will evacuate, and agree that in the mean time he will not use his guns against us, unless ours should be employed against Fort Sumter. You can thus avoid the effusion of blood. If this order should be unequivocally refused, reduce the Fort as your judgement decides to be the most practicable.
L. P. Walker, Secretary of War.
