In times of slavery in the US, there was a network of friendly people and places that slaves used to migrate from the South to the North. That network was known as the Underground Railroad.
One of the most famous people to be a ‘conductor’ of the railroad was Harriet Tubman. The woman made 19 journeys and freed more than 300 slaves.
She was so wanted that there was a reward for about $1 million in today’s dollars. Why was she so successful? She had some very good techniques.
For example, she threatened to shoot people who changed their minds and wanted to go back. She knew that if they went back that would risk her entire network.
One of the most interesting, and perhaps controversial things she did is she drugged small kids. Recognizing that they might slow down the group or give them away by crying at the wrong moment, she always carried an offshoot of opium to make them sleep.
