But your buddy DiogenesLamp implied those order were still secret and unknown to us today, when in fact they were first published in the New York Times later in 1861.
So there is nothing "secret" about them today.
Nor is there any mystery as to what they ordered.
These "secret" orders said the same thing that Lincoln directly told South Carolina Governor Pickens at the time:
Lincoln's mission was to resupply-only Fort Sumter and no reinforcement would be attempted so long as they met no resistance.
Reinforce was the order from the President, herewith documented.
April 4, 1861
To: Lieut. Col. H.L. Scott, Aide de Camp
This will be handed to you by Captain G.V. Fox, an ex-officer of the Navy. He is charged by authority here, with the command of an expedition (under cover of certain ships of war) whose object is, to reinforce Fort Sumter.
Winfield Scott
Approved by A. Lincoln
