What was to be done for the South, what treatment should be accorded the Southern leaders, engrossed the President and his Cabinet at the meeting on the 14th of April, which was destined to be their last. Secretary Welles has preserved the spirit of the meeting in a striking anecdote. Lincoln said that no one need expect he would "take any part in hanging or killing those men, even the worst of them. Frighten them out of the country, open the gates, let down the bars, scare them off;" said he, throwing up his hands as if scaring sheep. "Enough lives have been sacrificed; we must extinguish our resentments if we expect harmony and union."

While Lincoln was thus arming himself with a valiant mercy, a band of conspirators at an obscure boardinghouse in Washington were planning his assassination. Their leader was John Wilkes Booth, an actor, brother of the much abler Edwin Booth. There seems little doubt that he was insane. Around him gathered a small group of visionary extremists in whom much brooding upon Southern wrongs had produced an unbalanced condition. Only a morbid interest can attach today to the strange cunning with which Booth laid his plans, thinking of himself all the while as a reincarnation of the Roman Brutus.
