Harriet Tubman escaped slavery in 1849 and then went back to Maryland about 13 times, bringing out some 70 people. Her work depended on a chain of Quakers, free Black ministers and abolitionists who hid and moved people north.
The route follows that chain from the Eastern Shore through Wilmington and Philadelphia to Niagara and Salem Chapel in St. Catharines, then to her farm at Auburn. Real routes were kept secret, so most pins are approximate.
In 1973 Paul Theroux set out from London Victoria on a four-month railway loop through Europe, the Middle East, the Indian subcontinent and Southeast Asia, then came back on the Trans-Siberian Railway. His travelogue, published in 1975, became a classic of the genre.
This route follows episodes the book's reviewers single out, from the Direct-Orient Express to Istanbul, Calcutta, Burma, Vietnam and Tokyo. The book's own text could not be checked, so some pins mark a city's station rather than a scene, and some places are not safe to visit now.
On the night of 14 April 1865 John Wilkes Booth shot President Abraham Lincoln at Ford's Theatre in Washington and escaped on horseback. Lincoln died the next morning in a house across the street; Booth was hunted down twelve days later in a Virginia barn, in what was then the largest manhunt in US history.
The route follows both threads in turn: the theater and the room where Lincoln died, then Booth's road south through the Navy Yard Bridge, a Maryland tavern, a doctor's farmhouse and a swamp, to the farm where it ended.
