Abraham Lincoln [SEP] Assassination
President Johnson was sworn in the next morning. Two weeks later, Booth was tracked to a farm in Virginia, and refusing to surrender, he was mortally shot by Sergeant Boston Corbett and died on April 26. Secretary of War Stanton had issued orders that Booth be taken alive, so Corbett was initially arrested for court martial. After a brief interview, Stanton declared him a patriot and dismissed the charge.
