On April 14, 1865, while picking up his mail at Ford's Theatre in Washington, D.C., Booth found out that Lincoln would be going to a play with his wife there that evening. Booth knew the play well. Booth met with his co-conspirators and made a plan to kill President Lincoln, Vice-President Johnson, Secretary of State Seward, and possibly General Grant—all around 10:15 that evening. That afternoon Booth prepared a peep hole into the balcony room the Presidential party would use. During the play, Booth quietly entered the unguarded balcony room. At 10:15 pm, following a line in the play he knew would get a laugh, Booth fired a pistol at point-blank range into the back of Lincoln's head. Booth escaped by jumping from the balcony onto the stage, where he shouted a triumphant line to the audience. He broke his leg during the jump, but escaped out the back door and onto his horse.
