How was Harriet Tubman fearless?

Harriet Tubman was a fearless woman. One reason why she was fearless was that she survived being a slave. She had endured horrible treatment, including having been beaten several times. She eventually escaped to freedom, leaving her entire family behind as she fled. Trying to escape to freedom was a very risky thing for a slave to do.
After she got her freedom in the North, she worked very hard to help other slaves, including her own family members, escape to freedom. She was actively involved in the Underground Railroad. She went back to the South a minimum of 19 times to help other slaves escape to freedom. There were offers of big rewards for her capture, but that didn’t stop her from taking the risk to help other slaves become free.
During the Civil War, Harriet Tubman worked with the North. She served as a nurse to help soldiers of all races. She also served as a spy and as a guide.
Harriet Tubman was clearly a very fearless woman.
