Harriet Tubman was the "conductor" of the underground railroad and had tremendous courage. Every time she rescued a handful of slaves, she made dangerous attempts to save another handful of slaves. She was also known as "Black Moses" because she acted like a god leading slaves to freedom. The underground railroad was made up of supporters that thought slavery was wrong. Those people offered food, water, and hiding places. Harriet Tubman led more than three hundred slaves to freedom and she never lost a passenger. Slave owners sent out huge rewards to find their slaves and Tubman.
