Once the warships were sent, the war was began.
Bombarding a fort into rubble is a pretty good indication of intent. Are you saying Davis had no control over that?
Lincoln decided to have a war, and Davis simply played the hand he had been dealt by Lincoln.
The ever popular "We were so stupid we fell right into Lincoln's trap" defense. Doesn't say a whole lot about the intellect of those running the Confederacy, does it?
davis only had all the control over whether war would come and how it would be waged. He didn’t have quite as much control over when he would surrender.
