How big was the price on Harriet Tubman’s head?

The reward for the capture of Harriet Tubman (c. 1820-1913), an ex-slave who became famous for helping southern slaves escape to freedom in Canada, went as high as $40,000.

Even so, she eluded bounty hunters, returning 19 times to the South and bringing over 300 slaves to freedom on what was called the Underground Railroad.

Tubman also served as a Union nurse, scout, and spy in the Civil War.
