George Atzerodt, the the conspirator in John Wilkes Booth ring originally assigned to murder Vice-President Johnson, fled Washington after President Lincoln's assassination. He was captured before dawn at the home of a friend near Barnsville, Maryland, around twenty miles from the capital. Delaware Cavalry Sergeant L.W. Gemmill who carried out the arrest, together with his six men, shared the $25,000 reward announced that same day by Secretary of War Stanton. Atzerodt was executed on July 7, 1865. (By John Osborne)
