Assassination conspirator Samuel Arnold is arrested in the morning at Fortress Monroe in Virginia
Samuel Arnold became the first of John Wilkes Booth's circle of conspirators in the Lincoln Assassination to be captured. He was held, manacled and hooded, aboard the U.S.S. Saugas. He was tried with his companions in May and was sentenced to life in prison for his role in the original plan to kidnap Lincoln. He served his sentence in Florida until President Johnson pardoned him in 1869. He died in 1906. (By John Osborne)
