[Non-Sequitur]

Then what were Fox and the warships doing in Charleston harbor the night of April 11, 1861?

If they had been in Charleston harbor on April 11 then they would have been peacefully landing food and supplies. But on April 11 they were still a number of miles off shore and on April 12 they were watching the Davis regime bombarding Sumter.

Well, glad to see you finally admit to evidence of Lincoln's gunboat diplomacy when faced with the loss of the tariff base.

"...on April 11 they were still a number of miles off shore."

Not true. The Harriett Lane arrived at Charleston on the evening of the 11th, just in time to fire on shipping entering the harbor, thus earning the honor of firing the first shot of the War.
