Not many slaves escaped to freedom. Out of the millions of slaves in the South, there were only 1,000 to 1,500 reported as runaways each year.
The reason why most slaves didn't try to escape was because of fear of the unknown North and of getting caught and punished. Yet, people still found ways to escape. About 100,000 slaves escaped to freedom.
Harriet Tubman was a famous conductor. She made nineteen dangerous trips from the South to the free states and Canada. She helped about 300 slaves escape to freedom in the 10 year span between 1850 to 1860.
