On July 5, 1865, President Andrew Johnson signs an executive order that confirms the military conviction of a group of people who had conspired to kill the late President Abraham Lincoln, then commander in chief of the U.S. Army. With his signature, Johnson ordered four of the guilty to be executed.
Confederate sympathizers David E. Herold, G. A. Atzerodt, Lewis Payne, Mary E. Surratt, Michael O’Laughlin, Edward Spangler, Samuel Arnold and Samuel A. Mudd were arraigned on May 9 and convicted on July 5 for “maliciously, unlawfully, and traitorously” conspiring with several others, including John Wilkes Booth, who had assassinated President Lincoln on April 14, 1865. In addition to targeting Lincoln, the conspirators had planned to kill General Ulysses S. Grant as he led Union armies in the Civil War against the southern states. Vice President Andrew Johnson, who succeeded Lincoln to the presidency, was also one of the group’s intended prey.
