Already posted quite enough proof that it is not. You don't want it to be true, but it is true non the less. Union officials continuously misled the confederates that they were going to evacuate the fort.
H3ll, they printed it in the Washington DC newspaper! How much more proof do you need that they had deliberately lied about what they were going to do?
I'm not going to fool with the rest of your message. If someone won't acknowledge demonstrable facts, it is pointless to argue with them.
Totally false as my detailed reviews of events in posts #1,037, 1,054 & 1,055 amply demonstrate.
When the Virginia deal fell apart, so did Lincoln's willingness to withdraw from Fort Sumter, and so he advised SC Governor Pickens of the coming resupply mission.
As for what newspapers of that time reported, well... you do understand, I'd assume, the concept of "fake news"?
No, it wasn't first invented by President Trump.
