Harriet Tubman has been posthumously recognized as a one-star brigadier general in Maryland’s National Guard. At a ceremony on Veterans Day, officials in the abolitionist’s home state honored her military service during the Civil War.

The legendary Underground Railroad conductor was the first woman to lead a wartime military action in the U.S.

While many learned about Tubman's work freeing enslaved people, her sophisticated military service often goes untold in history classes.
