And as I said, neither the Official Record or any of the other books on Sumter that I've read include the Atlantic or the Illinois in any attempt to resupply Sumter. The Atlantic did bring troops to Pickens after the Sumter attack, but fewer than half the number you mention. So you can repeat Klein's summary all you want, it is not supported by any evidence I've seen. And you're summary also neglects to mention that the Baltic was also loaded with food and supplies destined for Sumter.
ust by itself, the Sumter supply fleet consisted of eight warships carrying 26 guns and 1,400 troops. (Rise and Fall of the Confederate Government by Jefferson Davis Volume 1 p284).
Davis' claims are even less accurate than your's are. There weren't 1400 troops available in New York to send to Sumter even if Lincoln had wanted to. He was scraping the bottom of the barrel to round up the few hundred that actually went.

And your source for that, that will refute both the Official Records, and Davis, and the US Naval Records?
