You know very well Jefferson Davis "launched the war", just as he promised in his February Inaugural Address.
And yet you continually claim otherwise -- for what reason, except to "drip with disdain in tone" regarding Lincoln, Northerners and Republicans in general?
Corwin was simply one of several Congressional attempts to find "compromise" that would appeal to Border State & secession state Unionists.
All failed with Confederates because they would have none of it, but did help preserve Border States in the Union.
I know no such thing. I know that Lincoln sent a fleet of warships to Charleston with orders to attack. Even Major Anderson said this would trigger the war, and he also he said he was ashamed of the Union starting the war in this manner.
Lincoln sent the fleet with orders to attack the Confederates. *THAT* is what started the war.
