Biography
Timothy Webster, an English-born operative of Pinkerton's detective agency, was one of the Union's most effective secret agents, moving through the South disguised as a secessionist courier. Betrayed after two fellow agents sent to check on him were recognized in Richmond, he was tried by the Confederacy as a spy and hanged there on 29 April 1862 — the first execution of a spy by either side in the Civil War.
Note: Pinkerton's institutional history gives April 30, 1862; this record uses April 29, 1862.
