Most people are unaware that Lincoln struck at them first, and that's because they don't teach that in history, because it makes Lincoln look like the aggressor, which he was.
“The attack on Ft. Sumter would not have happened had Lincoln not sent a fleet of warships to attack the Confederates around Sumter. It was the arrival of the first of the warships that triggered the attack.”
That’s nonsense. Lincoln sent ships to resupply the Fort with food only, and notified the confederates that was his plan.
The attack on Fort Sumter was the stupidest act of statecraft until December 7, 1941 was even stupider. Confederate Secretary of State Robert Toombs warned Jeff Davis just how disastrous his planned attack would be, but to no avail.
