If you are tired, keep going; if you are scared, keep going, if you are hungry, keep going; if you want to taste freedom, keep going.These are the words of Harriet Tubman, called the "Moses of her people" for leading slaves northward to freedom. After successfully escaping when only in her twenties, she put herself in danger again and again in order to help other slaves achieve liberty. And when the Civil War began, this freedom fighter not only spied for the Union, but became the first American woman to plan and direct a battle. Her compelling story is beautifully told here, along with a rich store of information about slave life, the Underground Railroad, and famous abolitionists.
