Four days after Gen. Lee surrendered, President & Mrs. Lincoln attended a play at Ford's Theater on April 14, 1865. While watching the play, President Lincoln was shot and killed by John Wilkes Booth. Lincoln's assassination was planned to be simultaneous with the assassination of the Vice-President, Andrew Johnson, and the Secretary of State, William Seward. Booth and his co-conspirators felt that killing the president and his two successors would leave the nation in turmoil, which would leave the Union without leadership and give the advantage to the Confederacy. Booth assigned George Azterodt to kill Vice President Johnson, but lost his nerve and did not carry through his part of the plan. Lewis Powell was assigned by Booth to kill Secretary Seward, and did injure Seward, his son, and his body guard, but they all recovered. At approximately 10:15 p.m., a famous actor and Confederate sympathizer, John Wilkes Booth, entered the president's private viewing box. He shot Lincoln in the back of his head then stabbed the soldier that was attending with Lincoln and jumped from the viewing box to the stage. He broke his leg in the fall but was still able to escape and leave Washington D.C. by horseback. A doctor, Charles Leale, who was also watching the play at the Ford Theater, ran to Lincoln's aid when he heard the commotion. Leale felt that Lincoln's injuries were too severe to make it the six blocks back to the White House, so he had Union soldiers carry Lincoln to a ground floor bedroom of a Petersen boarding house across the street. At the boardinghouse is was determined that Lincoln's injuries were fatal & he would not live through the night. It was reported that Lincoln never gained consciousness after the fatal shot at the theater. Lincoln's wife, Mary, was emotionally exhausted, grief-stricken, and in shock. Lincoln spent the night surrounded by his wife, his son, and 13 Government officials. President Abraham Lincoln sadly passed away at 7:22 the next morning, April 15, he was only 56 years old at his death. Booth was able to escape Washington D.C. unnoticed and he hid out for several days along a planned escape route. Union soldiers finally found, captured, and killed John Wilkes Booth on April 26, 1865. John Wilkes Booth worked with four people to carry out the assassination plan. They were Dave Herold, George Azterodt, Lewis Powell, and Mary Surratt. Booth's accomplices were arrested and later hung for their association with Booth. Mary Surratt was the first woman hung for a federal crime.
