As was Jefferson Davis, and for a longer period than Lincoln was.
It was Lincoln’s decision to call up 75,000 troops for an invasion rather than let events play out short of war.
Having bombarded Sumter into surrender then war was what the Southern states had already decided on. Lincoln's call for troops was merely in response to that.
The battlefields are in the south, not the north, a fact ignored since its meaning is obvious on its face.
I'm not sure what your obvious meaning is. The South started the war. The fact that you can't then keep your enemy off your territory is hardly your enemy's fault.
Lincoln’s decision for war, and he made this on his own Congress being out of session, pushed the wavering border states into joining the Confederacy, guaranteeing a long and bloody war.
Again, the case could be made that war was forced upon him.
” Again, the case could be made that war was forced upon him. “
He wasn’t that weak willed. The drive for war was coming from Radical Republicans like Charles Sumner and Massachusetts Gov Andrew. They had been demanding war before Lincoln even took office, before Ft Sumter. Lincoln had some of them in his Cabinet. He made the bad decision of giving them what they had been demanding.
