She was free. She had walked ninety miles through the dark to reach it. And then Harriet Tubman did something almost no one else would dare: she turned around and walked straight back into danger — not once, but again and again — to lead other people out too.
She was born around 1822 in Maryland and named Araminta Ross. She was enslaved from birth, hired out to strangers before she was six and whipped so often that she carried the scars for life. When she was about twelve, an overseer hurled a heavy metal weight at another enslaved person and struck Harriet in the head instead. The blow cracked her skull. Ever after, she suffered sudden headaches and spells of deep sleep that could seize her without warning.
In 1849, Harriet slipped away alone, following the North Star and the quiet help of the Underground Railroad — a secret chain of brave people and hidden safe houses. Traveling by night, she crossed into Pennsylvania and, at last, into freedom.
But freedom felt hollow with her family still in chains. Over the next ten years she went back to the South again and again, guiding roughly seventy people north. Folks began calling her Moses, after the Bible hero who led his people out of slavery. She was fiercely proud that she never lost a single passenger, and she was never caught.
After a cruel new law let slave-catchers hunt escapees even in the northern states, Harriet led people all the way to Canada, where they could finally be safe.
When the Civil War came, she served the Union Army as a cook, nurse, scout, and spy. She even helped lead a daring river raid that freed more than seven hundred enslaved people in a single night — becoming the first woman known to lead an armed military mission in America.
Afterward she settled in Auburn, New York, and joined the fight for women's right to vote. She died in 1913, honored ever since as one of the bravest people this country has known.
