John Wilkes Booth
On March 4, 1865, Booth attended Lincoln's second inauguration as president. Booth appears in some photographs taken that day. On March 15, Booth and most of his conspirators met at a restaurant three blocks from Ford's Theater to plan the kidnapping. Soon after, Booth heard that on March 17, the President would be seeing a play called Still Waters Run Deep at the Campbell Hospital, near Washington, D.C. Booth decided that this was the best time to kidnap him. According to John Surratt, Booth made a plan to intercept Lincoln's carriage on the way to the play.  However, President Lincoln changed his plans and decided to speak to the 140th Indiana Regiment and present a captured flag.
