@WaterHopper: Lewis Powell was assigned to assassinate Secretary of State William Seward on April 14, 1865. Seward was at his residence recovering from a serious injury resulting from a carriage accident.
Powell pretended to be delivering medicine for Seward. Once he gained access to Seward’s home, he was confronted by Frederick, Seward’s son. He was told Seward was sleeping and couldn’t go in. Powell swung around and pointed the gun at Frederick’s head. His gun jammed, so he struck him over and over again in the head with the pistol.
He ran into Seward’s bedroom and stabbed him several times in the neck and chest but the injuries were not fatal due to the fact that he was wearing a neck brace from the carriage accident. He attacked another son, Augustus, a solider, nurse and a messenger while escaping. All of those attacked survived their injury’s including William Seward. Powell was hung on July 7, 1865.
William Seward died on October 10, 1872 in Auburn New York. Most likely he died from natural causes.
