In Washington, Secretary of State Seward is injured quite badly when thrown from his carriage

William Henry Seward, the Secretary of State, was injured when he was thrown from his carriage when its horses were startled near Vermont Street in the capital.  He suffered a broken arm and severe bruising to his face and neck.  He was still confined to his bed at his home when Lewis Powell attempted to assassinate him nine days later.  He survived that attack, too, but with further injuries.  (By John Osborne)
