Those troops were ordered not to reinforce Sumter so long as there was no Confederate resistance.

The one thing that is absolutely known is that the commander of the Mission had secret orders.

Why secret orders for a resupply mission? Were the ships carrying secret Bacon, or Secret flour?

And so you, ahem, conjecture that those allegedly "secret orders" which we don't know about somehow contradicted those other official orders which we do have on record?
I don't think so.
Links have been posted to copies of orders which confirmed Lincoln's message to SC Governor Pickens, that no Union troops would reinforce Fort Sumter if they met no resistance.
