No, the first "act of war" could be interpeted as Anderson's aggressive move to Fort Sumter or The Star of West trying to reenforce Fort Sumter or the Firing on the Star of the West or the Capture of the garrison at Pensacola Naval Yard (the first POWs of the war). Take your pick, the point is there were people in power, on both sides, who did not try to avoid war (Lincoln being worst), except for the peace delegates from the South who were snubbed by the White House, but the South did try to keep the emergency fair and legal, for the most part the North did not.
