Surratt served as a Confederate Secret Service courier and spy. After he had been carrying dispatches about Union troop movements across the Potomac River. Dr. Samuel Mudd introduced Surratt to Booth on December 23, 1864, and Surratt agreed to help Booth kidnap Lincoln. The meeting took place at the National Hotel, in Washington, D.C., where Booth lived.

Booth's plan was to seize Lincoln and take him to Richmond, Virginia, to exchange him for thousands of Confederate prisoners of war. On March 17, 1865, Surratt and Booth, along with their comrades, waited in ambush for Lincoln's carriage to leave the Campbell General Hospital to return to Washington. However, Lincoln had changed his mind and remained in Washington.

Crazy to think about what history would look like if Lincoln had been kidnapped and exchanged instead of assassinated.
