Because the Underground Railroad had to operate in deep secrecy, many basic facts about its history are unknown. No one knows exactly how many men and women were involved in the railroad or how many fugitives were assisted by those committed to the cause. Certainly tens of thousands of slaves, aided by more than 3,200 railroad 'workers,' escaped to the northern states and Canada, and today scores of little towns from Maine to Iowa have their secrets about the railroad. This book captures beautiful photographs and stories depicting the Underground Railroad.
