[Non-Sequitur]

Which resulted in Buchanan failing to order him back, and the rebellion and resignation of some of his cabinet members.

Which ones? And if all this is against orders then why did Buchanan try to reinforce and resupply Sumter a month later?

With regard to resignations, I have seen several reports, but most likely, from the reports, there were 4: two because he would not order Anderson back (including Mr. Floyd) and two for not immediately ordering the US Fleet in.

And if all this is against orders then why did Buchanan try to reinforce and resupply Sumter a month later?

Several sources say that it was to please the hawks in the Republican party.

But the point being lost in your questioning is why would he order the 'Star of the West' in against the opinion of the Attorney General of the United States?
