United States: John Wilkes Booth is Killed
On the 14th April 1865, John Wilkes Booth assassinated the President of the United States of America at Ford’s Theatre, in Washington D.C. Booth, a Confederate sympathizer, managed to escape the scene of his crime and fled on horseback to a farm in northern Virginia. It was here, 12 days after his attack on the president that Booth was shot and killed.
John Wilkes Booth was born on the 10th May 1838, into the well known Booth family and became a well known actor in his own right. But it would be his assassination of Abraham Lincoln that he would always be remembered for.
Eight other co-conspirators were tried and convicted for their parts in the assassination and other roles in the plot that resulted in the death of the president. Four of these were hung a short time later.
