John Wilkes Booth knew the shot he fired at Abraham Lincoln was fatal. He had a simple plan for his getaway. He ordered a stagehand to hold his horse at the side door and he fled Washington D.C. as fast as he could go.
Booth, meanwhile, had made good time getting out of town. He crossed the Navy Yard Bridge into Maryland, and met one of his co-conspirators, 21-year-old David Herold.
